Beschreibung
Zusammenfassung:	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.
