What is the rubber composition and function of the airplane tyres?
Ethylene propylene rubber and ethylene propylene rubber are synthesized with ethylene and propylene as main raw materials. They are resistant to aging, electrical insulation and ozone resistance. Ethylene propylene rubber can be filled with oil and filled with carbon black. The price of the product is low, and the chemical stability of the ethylene propylene rubber is good. The abrasion resistance, elasticity, oil resistance and the proximity of styrene butadiene rubber are close. Ethylene propylene rubber is widely used. It can be used as tyre, sidewall, rubber strip and inner tube, as well as parts of automobile. It can also be used as wire, cable sheath and high voltage and extra high voltage insulating material. Can also manufacture rubber shoes, sanitary products and other light colored products. It is a chloroprene rubber as the main raw material, made by homopolymerization or copolymerization of small amounts of other. Such as high tensile strength, heat resistance, light resistance, aging resistance and oil resistance properties are superior to natural rubber, styrene butadiene rubber, butadiene rubber. It has a good flame resistance and excellent resistance to burning, its chemical stability is high, water resistance is good. Chloroprene rubber is electrical insulation, cold resistant performance is poor, rubber is not stable in storage. Neoprene is widely used, such as the manufacture of transport belts and belts, wires and cables, and the manufacture of oil resistant hoses, gaskets, and chemical resistant equipment linings.
Polybutadiene rubber is prepared by the solution polymerization of butadiene butadiene rubber, with excellent cold resistance, abrasion resistance and flexibility, but also has good anti-aging properties. Polybutadiene rubber is mostly used in the production of tires, a small part for manufacturing cold products, cushioning materials and belt and rubber shoes. Butadiene rubber drawback is the tear resistance of the cross, wet skid resistance is not good. Isoprene rubber is the abbreviation of polyisoprene rubber. It is produced by solution polymerization. Isoprene rubber, like natural rubber, has good elasticity and wear resistance, excellent heat resistance and good chemical stability. Isoprene rubber (not before processing) strength was significantly lower than that of natural rubber, but the quality uniformity, processing performance is better than natural rubber. Isoprene rubber can be used instead of natural rubber to make heavy-duty and off-road tires, and can also be used to produce all kinds of rubber products.
Rubber is divided into natural rubber and synthetic rubber. Natural rubber is mainly derived from the Hevea tree. When the epidermis of this rubber tree is cut open, it will shed milky juice. It is called latex, and the latex will be natural rubber when it is condensed, washed, molded and dried. Synthetic rubber is made by synthetic methods, and different kinds of rubber can be synthesized with different raw materials (monomers). Between 1900 and 1910, chemist C.D. Harris (Harris) measured the structure of natural rubber as a polymer of isoprene, which opened the way for synthetic rubber. In 1910, Russian chemist SV Lebedev (Lebedev, 1874 - 1934) with sodium initiator 1, sodium 3 - butadiene rubber polymerization into small, then there are many new varieties of synthetic rubber, such as polybutadiene rubber, chloroprene rubber, styrene butadiene rubber and so on. The yield of synthetic rubber has greatly exceeded that of natural rubber, of which the largest yield is styrene butadiene rubber. General rubber glue refers to replace some or all use such as natural rubber, styrene butadiene rubber, butadiene rubber, isoprene rubber, mainly used in the manufacture of tyres and rubber products industry. General purpose rubber is in great demand and is the main variety of synthetic rubber. Styrene butadiene rubber styrene butadiene rubber [1] is made by copolymerization of butadiene and styrene. It is the largest synthetic rubber with milk, styrene butadiene rubber, styrene butadiene rubber and thermoplastic elastomer (SBS).
