Jinan conference of the hottest reclaimed rubber i

The Jinan meeting of the renewable rubber industry issued an environmental protection initiative

proposal for the production and use of environmentally friendly renewable rubber

on November 10, 2011, Xinhua reported that the export of EU tires encountered a new threshold, and the relevant departments reminded enterprises to pay attention to risks. It was learned that the second half of the EU's strict detection of polycyclic aromatic hydrocarbons can be input into the experimental set parameters, making the export of Chinese tires and rubber products to the EU hit a new environmental threshold

on October 17 this year, the European tire and Rubber Manufacturers Association (etrma) announced the results of the second batch of spot checks on the content of polycyclic aromatic hydrocarbons in tires in the EU market. A total of 10 tires of 9 brands were detected to be beyond the limit, of which 9 were produced in China. Previously, in the first batch of spot check results released on March 1, 12 unqualified tires were all produced in China. Recently, etrma once again urged the EU and its member states to strengthen the supervision and law enforcement of polycyclic aromatic hydrocarbons in tires

in order to build a strong country in the world rubber industry and promote the development of green industrialization, according to the opinions on the development strategy of a strong country in the world rubber industry, the waste rubber comprehensive utilization industry is required to provide the rubber industry with reclaimed rubber products that comply with REACH regulations

in this regard, China's waste rubber comprehensive utilization industry firmly supports, supports and responds to this. Enterprises implement ISO14001 and OHS to protect the environment. At the same time, this material also has the characteristics of light weight. As18001 standard ensures the health of employees and meets the commitments of relevant environmental protection laws and regulations. As an industrial structure adjustment, product upgrading, elimination of backward production capacity, and industrial upgrading; We will eliminate the use of coal tar as the main softener to produce high-strength reclaimed rubber in the whole industry, and use bio oil and vegetable oil to produce environmentally friendly reclaimed rubber in line with REACH regulations

using coal tar as softener, the reclaimed rubber produced by it has small elasticity, large Mooney fluctuation, poor processing performance and easy mold fouling; The finished rubber products produced with it are prone to yellowing, cyaning and other color migration phenomena. After testing, the content of polycyclic aromatic hydrocarbons (PAHs) in 18 items is as high as more than 2200mg/kg, and the content of polycyclic aromatic hydrocarbons (8 items) is as high as 638.1mg/kg, which far exceeds the requirements of relevant regulations in developed countries such as Europe and the United States

at present, the waste rubber comprehensive utilization industry has developed and promoted environmental friendly reclaimed rubber products that comply with the REACH regulations. The softeners used are mainly pine tar, wood tar, rosin, tall oil, saponin oil, cottonseed oil, rapeseed oil and other plant series. The content of 18 polycyclic aromatic hydrocarbons (PAHs) in the reclaimed rubber produced by it is determined to be within g/kg of the 100m carton compression tester Jinan testing machine factory; The content of polycyclic aromatic hydrocarbons (8 items) is within 100mg/kg; Six and fifteen substances of high concern (SVHC) in the determination of harmful heavy metals have added color to the metallographic laboratory! The measured data are in line with European and American environmental protection testing standards; In the process of use, there is no odor, no toxic and harmful gas volatilization, and no harm to human body. The processing performance of environment-friendly reclaimed rubber is better than that of polluting reclaimed rubber, which does not pollute the mold, and there is no yellowing, cyaning and other color migration phenomena. The chemical composition index also meets the requirements of relevant laws and regulations in developed countries such as Europe and the United States. At present, foreign customers and some domestic rubber products export enterprises use this kind of environment-friendly reclaimed rubber

in order to promote the green industrialization development of the rubber industry, promote the product transformation of the waste rubber comprehensive utilization industry, and promote the development and promotion of the production process of environmental friendly reclaimed rubber, the industry has started to revise the standard of reclaimed rubber, and at the same time, it is suggested that the whole industry should start from me: establish a people-oriented awareness, refuse to use coal tar as a softener to produce reclaimed rubber, and refuse to use reclaimed rubber whose product quality does not meet the requirements of REACH regulations. We need the support of the national rubber industry. Here, entrepreneurs, experts and technicians who produce and use recycled rubber tires, bicycle tires, rubber hose tapes, shoes, seals and other rubber products are responsible for their own lives and society

although the price of biological and plant softeners is higher than that of coal tar, the production cost of environmental friendly reclaimed rubber is higher than that of polluting reclaimed rubber; Although coal tar has some influence on the elongation and strength of reclaimed rubber; However, to eliminate coal tar is the need of enterprise development, industrial upgrading, and social development. It will benefit the contemporary and contribute to the future
