Abstract
The invention provides a rubber formula. Rubber prepared according to the formula comprises the following components in parts by weight: 80-100 parts of natural rubber, 20-40 parts of ethylene-propylene rubber, 3-5 parts of coumarone resin, 1-2 parts of zinc oxide, 3-5 parts of anti-aging agent, 1-2 parts of accelerant PZ, 1-1.5 parts of white carbon black and 20-30 parts of naphthenic oil. The rubber has relatively low hardness; and in addition, the relatively strong binding power exists between the rubber and a framework so that a stable bonding effect is ensured.
Description
Technical field
The present invention relates to rubber compounding technical field, be specifically related to a kind of rubber compounding, this rubber has lower hardness, and between skeleton, has stronger bounding force.
Background technology
In order to meet the performance requriements of component, the engine support of for example being made by skeleton and rubber adhesion, the durometer level that requires natural rubber unvulcanizate is 40 ± 3, tensile strength requires to be greater than 17Mpa, the hardness ratio of this rubber is lower, tensile strength is higher, and makes to have stronger bounding force to guarantee stable bonding effect between this rubber and skeleton, thereby guarantees in process of production the stability of quality product.
Summary of the invention
The object of the invention is to solve existing technological deficiency, a kind of rubber compounding is provided, this rubber has lower hardness, and between skeleton, has stronger bounding force.
The technical solution adopted in the present invention is: a kind of rubber compounding, and in this formula, each component and content are as follows:
Natural rubber 80-100 part
Ethylene-propylene rubber(EPR) 20-40 part
Coumarone indene resin 3-5 part
Zinc oxide 1-2 part
Anti-aging agent 3-5 part
Promotor PZ 1-2 part
White carbon black 1-1.5 part
Naphthenic oil 20-30 part.
Further, described anti-aging agent is N, N'-di tolyl p phenylenediamine.
The invention has the beneficial effects as follows: this rubber has lower hardness, and between this rubber and skeleton, there is stronger bounding force to guarantee stable bonding effect.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
