Goal of the invention：In order to solve in the presence of prior art the problem of, the present invention, which proposes one kind, effectively to be changed It is apt to the product of rubber and plastic mechanical property of fire resistance, anti-high and low-temp performance, anti-wear performance, tensile resistance and the intensity of product of rubber and plastic Modifying agent.

Technical scheme：To achieve these objectives, the present invention takes following technical scheme：

A kind of product of rubber and plastic mechanical property modifying agent, the preparing raw material of following components is included according to weight meter：Resinae 15- 20 parts, 5-10 parts of polyethylene, 3-6 parts of silane coupler, 5-12 parts of carboxylic acid compound, 4-6 parts of water reducer, epoxide 3- 6 parts, 3-7 parts of phosphite ester, 1-5 parts of toughener, 3-6 parts of plasticiser, 2-5 parts of anti-wear agent.

Further, the resinae is the mixture of flame-retardant resin and phenolic resin.

Further, in the resinae content of flame-retardant resin more than 50%.

Further, the epoxide is one kind in expoxy propane, epoxy silicon oil, epoxychloropropane.

Further, the carbon atom number of the carboxylic acid compound is not less than 6.

Further, the toughener is haloflex.

Further, the plasticiser is environment-friendlyplasticizer plasticizer.

Further, silicone oil is not less than 20% in the anti-wear agent.

Beneficial effect：A kind of product of rubber and plastic mechanical property modifying agent that the present invention is provided, exists for existing product of rubber and plastic Defect, by resinae, polyethylene, silane coupler, carboxylic acid compound, water reducer, epoxide, phosphite ester, increasing Tough dose, plasticiser, the preparing raw material such as anti-wear agent constitute, product of rubber and plastic mechanical property modifying agent of the invention, it is not only nontoxic, Good weatherability, with preferable stability, be applied to gone in product of rubber and plastic obtained finished product there is preferable fire resistance, it is wear-resisting Performance, tensile resistance and intensity, and for a long time in hot environment still be able to keep good mechanical performance, be unlikely to deteriorate by Damage, service life is long, with very strong practical value.
