Problems solved by technology

[0003] When rubber is catalyzed by heat, light, ozone oxidation or metal ions during processing, use or storage, it is easy to undergo autocatalytic reactions, molecular chain scission or excessive crosslinking, so that the surface will gradually change color, bloom and stick. , hardening, brittleness, cracks, etc. At the same time, its mechanical properties will also decline significantly, and even lose its use value, thus limiting the application of rubber materials

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a preparation method and application of a corrosion-resistant rubber composite material. Background technique [0002] Rubber is an elastic polymer. As an important strategic material, it is widely used in high-tech, national economy, national defense and military industries. Rubber can be divided into general-purpose rubber and special rubber according to performance and use. General-purpose rubber has good comprehensive properties and is widely used. Mainly include: Natural rubber: It is made from the latex of the Hevea trilobata tree. The basic chemical composition is cis-polyisoprene, which has good elasticity, high strength and good comprehensive performance. Isoprene rubber: High-cis synthetic rubber made from isoprene, which is also called synthetic natural rubber because of its structure and properties similar to natural rubber. Styrene-butadiene rubber: It is...
