Abstract

The invention relates to a rubber modified master-batch. The rubber modified master-batch comprises the following components of activated rubber powder, matrix asphalt and polycrystalline silicon wastes in the weight ratio of (90-105) : (2-38) : (1-30), wherein the activated rubber powder comprises the following components of used tires and activators in the weight ratio of (94-100) : (2-10). Therubber modified master-batch provided by the invention has the advantages of low temperature resistance, better oxidative resistance and good elasticity; the rubber modified master-batch is heated ata high temperature of 200 to 250 DEG C by the matrix asphalt, the rubber modified master-batch and the matrix asphalt are mixed, diluted and chloridized to obtain synthetic rubber asphalts with excellent performance; and the rubber modified master-batch can be mixed with other rubbers and vulcanized at high temperature by using a vulcanization section die or mixed with plastics and chloridized toprepare a rubber and plastic product.

Description

technical field [0001] The invention relates to a rubber modified master batch, in particular to a rubber modified master batch containing polysilicon industrial waste silicon tetrachloride. Background technique [0002] At present, the rubber powder processed from waste tires is mainly composed of rubber and various tire manufacturing additives, which has poor compatibility with other materials, so it affects its application range. It must be activated to regain the properties of raw rubber. To a certain extent, the viscous properties are restored; the activated rubber powder can be used in the fields of matrix asphalt modification, rubber-plastic composite materials, etc. [0003] In order to improve the adhesion performance of waste rubber particles, the current method used in the industry to activate waste rubber is to use tert-butylphenol formaldehyde resin as the vulcanizing agent and stannous chloride as the vulcanization system of the accelerator, and use the halogen...
