Abstract
The invention relates to a vulcanizing system of ethylene-propylene diene rubber. Used for vulcanizing 100 parts by weight of the ethylene-propylene diene rubber, the vulcanizing system comprises the following components in parts by weight: 15-30 parts of reactive resin used as a main vulcanizing agent, 1-2 parts of peroxide used as an auxiliary vulcanizing agent and 2-5 parts of maleic amide used as auxiliary crosslinking agent and anti-reducing agent, as well as 0.5-1 part of activator, 1-3 parts of accelerant, 10-15 parts of reinforcing agent, 2-4 parts of anti-aging agent and 10-30 parts of filling agent which are added during vulcanizing process. The vulcanizing system of the ethylene-propylene diene rubber can be used for effectively improving the high-temperature resistance of the rubber by using the reactive resin as the main vulcanizing agent, improving the crosslinking density and physical properties of the rubber by using a small quantity of peroxides as the auxiliary vulcanizing agent, further improving the crosslinking density and high-temperature resistance of the rubber by using the maleic amide as the auxiliary crosslinking agent and anti-reducing agent, and realizing a co-vulcanizing effect by using the activator and the accelerant to result in the concerted reaction of the vulcanizing system.
Description
Technical field
The present invention relates to the rubber conveyer belt production field, especially a kind of terpolymer EP rubber vulcanization system.
Background technology
Usually adopt sulphur, superoxide, reaction resin, maleinamide compounds as the mainstreaming agent to the sulfuration of terpolymer EP rubber in the industry at present, but generally all adopt independently vulcanization system.Vulcanize resulting terpolymer EP rubber like this, resistance to elevated temperatures is relatively poor, being subjected to decomposition easily under the extraneous high-temperature condition, rubber conveyer belt is damaged.The cross-linking density of simultaneously such terpolymer EP rubber is low, causes the physicals of rubber conveyer belt poor.
Summary of the invention
The objective of the invention is provides a kind of terpolymer EP rubber vulcanization system that can improve the physicals and the resistance to elevated temperatures of terpolymer EP rubber for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the terpolymer EP rubber vulcanization system that the present invention is designed, terpolymer EP rubber to 100 parts vulcanizes, with 15-30 part reaction resin as main vulcanizing agent, with 1-2 part superoxide as auxiliary vulcanizing agent, with 2-5 part maleinamide as auxiliary crosslinking agent and anti-reductive agent, and in sulfidation, add 0.5-1 part promoting agent, 1-3 part promotor, 10-15 part toughener, 2-4 part anti-aging agent and 10-30 part weighting agent, above umber is parts by weight.
Promoting agent is a lead compound.
Anti-aging agent is thiol group benzoglyoxaline or octylated diphenylamine.
Promotor is the sulfate-phosphate derivative.
Toughener is carbon black or silicate.
Weighting agent is an activated earth.
The resulting terpolymer EP rubber vulcanization system of the present invention adopts reaction resin as the mainstreaming agent, can effectively improve the resistance to elevated temperatures of rubber.Use a spot of superoxide as auxiliary vulcanizing agent, can improve the cross-linking density of rubber, improve the physicals of rubber.Adopt maleinamide as auxiliary crosslinking agent and anti-reductive agent, further improve the cross-linking density and the resistance to elevated temperatures of rubber.Adopt promoting agent and promotor to make whole vulcanization system concerted reaction in addition, and reach the covulcanization effect.
Embodiment
The present invention is further described by the following embodiment.
