Abstract

The invention discloses a preparation process of ethylene propylene diene rubber foaming materials. A rubber compounding recipe of the invention consists of ingredients of rubber base materials, an anti-aging system, a filling system, a plasticizing agent, a vulcanizing system, a foaming system and a radiation cross linking sensitizing agent. The ethylene propylene diene rubber foaming materials are prepared through vulcanization foaming and demolding after the pretreatment of compounding, sheet cutting and electronic beam radiation pretreatment. The rubber sheets of the invention after radiation pretreatment have a certain pre-cross-linking degree before the heating vulcanization foaming, the fit of the vulcanization speed and the foaming velocity can be realized, the integral performance of products can be improved, the pre-vulcanization time can be shortened, energy sources can be saved, and the production efficiency can be improved.

Description

Technical field [0001] The invention relates to the technical field of rubber foam material preparation, in particular to a preparation process of an EPDM rubber foam material. technical background [0002] Rubber foam materials have excellent characteristics such as vibration reduction, heat insulation, sound insulation, and good resilience, so they are widely used in automotive door and window sealing tapes, cushions, gaskets for building materials, heat insulation parts for low-voltage electrical appliances, and shock absorption Components, protective components for leisure or sports facilities, etc., as well as shock-absorbing components used in rail transportation. EPDM rubber compound has good ozone resistance, heat resistance, weather resistance, and low temperature flexibility. It can be used in occasions that require ozone resistance, weather resistance, and UV resistance. Therefore, it has become the most commonly used rubber hair Bubble material. [0003] At present, t...
