Suggestions on "Accelerating the Development of Natural Eucommia Rubber Industry, a Strategic Green Emerging Industry in China".

National Development and Reform Commission:

　　The important decision of the state on "accelerating the cultivation of strategic emerging industries" is of great significance for transforming the mode of economic development, adjusting the industrial structure, integrating the urban and rural social pattern, and promoting the coordinated development of the region in a forward-looking manner. We believe that "creating strategic green emerging materials - natural rubber intensive industrial development" is an emerging industry with great development potential and in line with the "strategic" development trend. Great industry. In view of this, the following suggestions are made:

　　First, natural eucommia rubber has excellent characteristics

　　Eucommia is China's unique valuable Chinese herbal medicine, but also the development of the highest potential for high-quality rubber tree species. Eucommia fruit, leaves and skin are rich in eucommia gum, which is the second largest source of natural rubber in the world that has not been developed in large quantities. The unique structure and properties of eucommia gum enable the development of three different types of materials for different purposes: rubber elastic (high elasticity) materials, thermoplastic materials and thermoelastic shape memory materials, which can be used in the rubber industry, aerospace, national defense, shipbuilding, chemical industry, medical care, sports and other sectors of the national economy, and the field of application covers a wide range of areas.

　　1. The modification and integration function of eucommia gum can enhance the performance of rubber composites such as wear-resistant, tear-resistant, corrosion-resistant, anti-slippery, low rolling resistance, energy-saving and so on, which can not only partially replace the natural rubber, but also develop the high-performance "long-life tires", "special tires" and so on. It is also a good material for developing high-performance "long life tires" and "special tires".

　　2. The polymer alloy modified by blending of eucommia gum has excellent film-forming, bonding, sealing and radar wave permeability properties.

　　Second, the importance and urgency of the development of dulcimer rubber industry

　　China is the world's largest consumer of rubber. According to the statistics of China Rubber Industry Association, the actual consumption of rubber in 2009 amounted to 5.88 million tons, ranking first in the world for 8 consecutive years, and the total industrial output value of rubber products industry in 2009 amounted to 430 billion yuan.

　　However, the scarcity of natural rubber (i.e., Brazilian triticale rubber) resources has become the most important problem restricting the development of China's rubber industry.

　　1. Natural rubber is mainly produced in Brazil, Southeast Asia and other places within 15 degrees of latitude north and south of the equator, China's introduction area is very narrow, only in Hainan Island and Xishuangbanna and other places to cultivate 10 million mu or so, with limited production capacity.

　　2. According to the China Rubber Industry Association statistics, in 2009 China's annual demand for natural rubber amounted to 2.7 million tons, the annual output of domestic natural rubber is only about 600,000 tons, 78% dependent on imports.

　　3. At present, the Southeast Asian natural rubber producing countries have formed an "industrial alliance", basic control of natural rubber "plantations" and prices, China's natural rubber raw materials subject to the increasingly serious situation, seriously affecting the sustainable development of China's rubber industry.

　　The development of the second natural rubber resources should become an important issue for our government to solve. The development of dulcimer rubber industry is the only way to fundamentally solve the lack of natural rubber resources in China, but also to accelerate the healthy development of China's rubber industry fundamental measures.

　　Third, the huge potential of dulcimer development

　　1. Application in tire industry:

　　60% of the world's rubber for tires, tire industry is the main battlefield of the rubber industry. Chinese Academy of Sciences Institute of Chemistry Yan Ruifang researcher in the early 1990s with natural dulcimer rubber and male rubber (synthetic rubber) according to 1:1 co-mingled made of motorcycle tires, safe driving for two years, intact, the formation of our country's original innovation and intellectual property rights system. Qingdao University of Chemical Technology with synthetic dutasteride rubber and styrene-butadiene rubber co-mingled radial tires, with anti-slippery, rolling resistance and other advantages, fuel savings of 2.5%, life expectancy increased by 20%.

　　2. Application in military, aviation and aerospace:

　　Duchess rubber has low temperature plasticity and shape memory characteristics, can be used to manufacture a variety of medical functional materials and vacuum sealing materials; Duchess rubber has good radar wave permeability and strong sealing properties, is used for aviation remote sensing, telemetry radar sealing of the emerging materials.

　　3. In orthopedic external fixation, prosthetic sets, athletes on the application of protective gear:

　　By applying the characteristics of low temperature plasticity of Dulcium Chinense gum, the products of orthopedic external fixation, prosthetic sleeve and athletes' protective gears have passed the appraisal and declared patents.

　　4. Extraction of eucommia gum pre-products in the development of health care products and feed additives:

　　In addition to the richness of eucommia gum in eucommia fruits, the seed kernel can also be used to extract eucommia oil. Eucommia oil high activity linolenic acid content up to 66.4%, for olive oil, walnut oil, tea oil in the α-linolenic acid content of 8 ~ 60 times, has a significant lowering of blood lipids, lowering blood pressure efficacy; Eucommia leaf traditional Chinese medicine function of the feed can significantly improve the quality of livestock and poultry meat, reduce egg cholesterol content, the development of green and safe Eucommia function of the product has a good prospect; in addition, Eucommia male flower amino acid content of 21.88%, for the In addition, the amino acid content of eucommia male flower is 21.88%, which is more than 2 times of pine pollen.

　　In short, the rapid development of eucommia rubber industry can not only enhance China's natural rubber production and rubber industry's international status and discourse, but also form a new pattern of international natural rubber market with China's eucommia rubber emerging industry as the leader. In addition, through the cultivation and comprehensive utilization of resources, it can greatly improve the economic benefits of farmers and promote the healthy development of the whole industry.

　　Fourth, China's eucommia natural rubber unique resource advantages

　　1. Eucommia fruit rind, bark, leaves and other parts are rich in eucommia gum, of which the content of eucommia gum in eucommia fruit is as high as 12% (eucommia fruit rind has a higher content of gum, up to 17%); 2.

　　2. At present, the cultivated area of eucommia is about 350,000 hectares, accounting for more than 99% of the total cultivated area of eucommia in the world, and it has monopoly resource advantage.

　　3. Eucommia tree is cold-resistant, drought-resistant, barren-resistant, with strong adaptability, and can be planted in 27 provinces (districts and municipalities) from subtropical to temperate zone in China, with great potential for development.

　　4. According to the development scale of 3 million hectares, the annual output of eucommia gum in China can reach 1.2 million tons, which is 2 times of the current natural rubber production in China, and it can greatly alleviate the situation of lack of natural rubber resources in the country.

　　Fifth, the technical basis for the development of industrialization of eucommia gum

　　Under the strong support of relevant state departments, Chinese Academy of Forestry, Chinese Academy of Sciences and other long-term systematic research on eucommia, in the cultivation of resources, pre-industrial research and comprehensive utilization and other aspects of the important research progress, for the development of industrialization of eucommia gum provides a good foundation.

　　1. Cultivation of resources: The Chinese Academy of Forestry has led the selection and breeding of four high-yielding gum dulcimer varieties, and adopted the orchardization cultivation technology, which has increased the fruit production of dulcimer by 40 times compared with the traditional cultivation mode, and the gum production per hectare is up to 400kg.

　　2. Pre-industrial research: The Institute of Chemistry of the Chinese Academy of Sciences (ICC) is the first institute in the world to make elastomers out of eucommia gum, and has developed rubber high elasticity materials, thermoplastic materials and thermoelastic shape memory materials. From the extraction of eucommia gum to the development of eucommia gum products, it has more than 10 patented technologies.

　　3. Comprehensive utilization of eucommia: through the successful research and development of series of products such as highly active linolenic acid oil of eucommia seed kernel and eucommia androgynous tea, the Chinese Academy of Forestry, Henan University and other units have not only greatly reduced and digested the production cost of eucommia gum, but also greatly enhanced the economic benefits of eucommia orchard per unit area.

　　Sixth, benefit analysis of eucommia gum industrial park

　　1. According to the development scale of 3 million hectares of high-yield eucommia gum orchard (equivalent to the current national oil tea cultivation area), the annual output value of eucommia gum and rare biomass primary products can reach 250 billion yuan, which is 12.5 times of the current annual output value of 20 billion yuan of the national oil tea, and the prospect of industrialization is very broad.

　　2. The rapid development of eucommia gum industrial park can effectively solve the social employment problem. Among them, the cultivation of eucommia resources can provide 4.5 million jobs (100 jobs per 100 hectares), digesting a large number of rural surplus labor; eucommia gum and rare biomass primary product production can provide 1.2 million jobs (100 jobs per 100 tons of gum extraction and product development), and effectively alleviate the problem of employment in our cities and towns.

　　3. Japan's Ministry of Economy, Trade and Industry, Ministry of New Energy Industry has aimed at China's dulcimer rubber resources, and established a dulcimer rubber experimental base in our country, to China's unique dulcimer rubber industry and the rubber industry has sounded the alarm.
