Problems solved by technology

[0002] Natural rubber is a linear natural polymer compound, and its chemical composition is mainly cis-1,4-polyisoprene, which contains a large number of unsaturated double bonds. During processing, use or storage, when exposed to heat, light, Ozone oxidation or the catalysis of metal ions, it is easy to carry out autocatalytic reaction, molecular chain breaking or excessive crosslinking, so that the surface will gradually change color, bloom, sticky, hard and brittle, cracks and other phenomena, while its mechanical properties There will also be a significant decline, or even loss of use value. In addition, as an organic polymer material, its flame retardancy is not very ideal. The existing natural rubber composite materials often have insufficient aging resistance when used in cables, wires, and electrical appliances. Good, flame retardancy is not ideal, thus limiting the application of natural rubber composites
