Problems solved by technology

[0002] EPDM rubber is mainly used in ordinary sealing products. Since the unsaturation of EPDM rubber is much lower than that of other unsaturated diene rubbers, when vulcanized with a vulcanization system, there is a relatively low vulcanization activity. Low, slow vulcanization speed, long vulcanization time

Abstract

The invention relates to a formulation for vulcanizing ethylene propylene diene monomer and a vulcanization method thereof, in particular to a formulation for rapidly vulcanizing ethylene propylene diene monomer and a vulcanization method thereof. The invention aims at providing the formulation for rapidly vulcanizing ethylene propylene diene monomer and the vulcanization method thereof; the method adopts a vulcanization system and multiple accelerating agents and even adopts part of high-activity excessive speed accelerating agent, and part of active agent is added, thereby further improvingvulcanizing reactivity of sizing material; vulcanization speed of the sizing material is increased to a larger extent and vulcanization time is reduced; simultaneously, formulation performance is increased than ever; the product produced according to the formulation has the advantages of good appearance, middle and high hardness, high anti-compression permanent deformation, high tensile strength and elongation at rupture, has excellent ageing resistance and ozone resistance performance, can keep good performance and appearance in a harsher using environment; the proportion of the raw materials of the product is reasonable; and the process is simple.

Description

technical field [0001] The invention relates to a formula for vulcanizing EPDM rubber and a vulcanization method thereof, in particular to a formula for rapidly vulcanizing EPDM rubber and a vulcanization method thereof. Background technique [0002] EPDM rubber is mainly used in ordinary sealing products. Since the unsaturation of EPDM rubber is much lower than that of other unsaturated diene rubbers, when vulcanized by a vulcanization system, there is a relatively low vulcanization activity. Low, slow vulcanization speed, long vulcanization time. For this reason, need a kind of formula and vulcanization method of vulcanized EPDM rubber that can solve the problem, meet the needs of actual situation with this. Contents of the invention [0003] The object of the present invention is to propose a formula and vulcanization method of a rapid vulcanization EPDM rubber, which adopts the method of using a vulcanization system and a variety of accelerators, even adopts a part of...
