Problems solved by technology

[0002] The harmful gas and waste products associated with the production of plastics and rubber have a common problem in the surrounding and plastic products industry, which is the pollution of the environment where the final product is formed. When the service life of plastic products reaches the limit, the phenomenon of discarding everywhere is becoming more and more. Serious, especially the untimely disposal of waste plastics has gradually caused public nuisance

Embodiment 1

[0025] A composite material of plastic and rubber, comprising the following components in parts by weight:

[0026]

[0027] A preparation method of a composite material of plastics and rubber, comprising the following steps:

[0028] (1) Put styrene-butadiene rubber, cis-1,4-polybutadiene rubber, 30% glass fiber modified polyamide and acrylonitrile-butadiene-styrene into the internal mixer at 100°C Plasticize for 5 minutes, deglue to obtain blended rubber and plastic;

[0029] (2) Then add modified white carbon black, plant fiber, sulfenamides, triallyl isocyanurate, unsaturated fatty acid zinc, sorbitan fatty acid ester and alkyl epoxide in sequence The adduct was mixed at 130°C for 5 minutes, and the next sheet was discharged to obtain a mixed rubber;

[0030] (3) Throwing the mixed rubber, sulfur and peroxide into an open mill for refining, cutting, and cooling in a cooling bucket at -5°C for 24 hours to obtain a mixed billet;

[0031] (4) Put the mixed blank into th...

Abstract

The invention discloses a plastic and rubber composite material which comprises the following components in parts by weight: 50-70 parts of a rubber plastic material, 25-45 parts of a filling agent, 1-5 parts of a vulcanizing agent, 0.1-1 part of an accelerant, 1-5 parts of an auxiliary agent and 1-6 parts of an active agent. An addition product of a natural surfactant sorbitan fatty acid ester with a compatibilization effect and an alkyl epoxide is added in an incompatible rubber / plastic polymer blend, and the addition product is also a dispersing agent, a phase dispersion-crosslinking synergistic effect is achieved, the dosage of the vulcanizing agent, the accelerant and the processing aid can be reduced by about 20% or above, the vulcanized composite material has good elasticity, compression deformation resistance, aging resistance and wear resistance, the cost is reduced and the competitive capacity is improved.

Description

technical field [0001] The invention relates to the technical field of rubber and plastic materials, in particular to a composite material of plastic and rubber and a preparation method thereof. Background technique [0002] The harmful gas and waste products associated with the production of plastics and rubber have a common problem in the surrounding and plastic products industry, which is the pollution of the environment where the final product is formed. When the service life of plastic products reaches the limit, the phenomenon of discarding everywhere is becoming more and more. Seriously, especially the untimely disposal of waste plastic products has gradually caused public nuisance. [0003] Rubber-plastic blending means that rubber and plastic are processed through specific means and methods, so that the resulting blended material has the dual characteristics of rubber and plastic. The two phases in the blend still maintain their respective characteristics, and no n...
