Problems solved by technology

Adding a co-crosslinking agent can exert its cross-linking effect at room temperature and improve the degree of vulcanization of the material, but the effect of the co-crosslinking agent used is limited, and it cannot really ensure that the vulcanization of the material is fully carried out. Degradation of the chain segment occurs, resulting in rapid deterioration of performance, so it is not suitable for use at high temperature
Secondly, the silicone rubber foam material vulcanized at room temperature is a material with a single matrix component, which can only reflect the performance of silicone rubber, and is not as good as the comprehensive performance of the material of the alloy matrix component, such as its heat resistance and mechanical properties are not as good as the alloy matrix Component materials are not suitable for use in high temperature and environments requiring high mechanical properties
[0004] Such materials have poor high temperature resistance, low mechanical properties, and low expansion ratio

Description

Technical field [0001] The invention involves a alloy material, which is specific to a high -temperature -resistant organic plastic alloy material and its preparation methods. Background technique [0002] At present, the demand for porous plastic alloys with high thermal temperature to resist temperature is increasing day by day, but there is no corresponding product corresponding to it, so the research and development of such products is imminent.High -heat -resistant plastic alloys are rare in the domestic market. A small number of sales and good reputation are basically imported products. The market share of domestic products is less. [0003] In order to improve the heat -resistant temperature of plastic alloys, some researchers have proposed to increase the degree of sulfurization of materials by adding the addition of cross -linking agents and using secondary radiation crosslinters, thereby increasing the heat -resistant temperature of the material.Join the cross -linking ...
