Abstract

The invention provides a composition as well as a preparation method and an application thereof. The composition is prepared from the following raw materials in parts by weight: 100+0.5 parts of EPDM (Ethylene-Propylene-Diene Monomer), 6+/-0.01 parts of activated zinc oxide, 0.5+/-0.01 part of stearic acid, 3+/-0.01 parts of antiager RD, 2+/-0.01 parts of anti-fog wax, 1.2+/-0.01 parts of rubber dispersant, 30+/-0.5 parts of carbon black N330, 35+/-0.5 parts of carbon black N550, 12+/-0.5 parts of softener, 4.5+/-0.005 parts of DCP (dicumyl peroxide) and 0.45+/-0.005 parts of vulcanizing agent POM (polyoxymethylene). The composition can be used for preparing high temperature resistant and atomized materials, so that the composition has the high temperature resistant and atomized requirements, so that the defects that in the prior art, the high temperature resistant time is not long, the atomization and the temperature resistance cannot achieve simultaneously, and the performances after heat resistance are obviously reduced are solved. The composition can be widely applied to the automobile industry and the electron industry, the production efficiency is improved, and the time and resource are saved.

Description

technical field [0001] The present invention relates to the field of high-temperature-resistant atomized materials, in particular to a high-temperature resistant and atomized composition. product applications. Background technique [0002] In recent years, EPDM (ethylene-propylene-diene-terpolymer rubber) has been widely used in automobile, construction, electronics, electrical appliances and other industries, mainly because of its outstanding heat resistance, ozone resistance and weather aging resistance Performance, especially good heat aging resistance, can be used for a long time in an environment of 120 degrees, and it can reach a high temperature of 150 degrees in a short period of time. Recently, in order to study the ability to withstand higher temperatures, many researchers are constantly debugging and designing formulas. For example: 100 parts by weight of PDM, 5 parts by weight of active zinc oxide, 1 part by weight of stearic acid, 2 parts by weight of antioxid...
