A kind of carbon carbon/rubber composite material preparation method

Abstract

The invention belongs to the technical field of rubber wet-method mixing, and particularly relates to a preparation method of a carbon-carbon / rubber composite material. The preparation method of the carbon-carbon / rubber composite material comprises the following three steps: preparation of rubber master batch mixed liquor, preparation of rubber master batch and preparation of the composite material. A filler is pretreated by technical means including stirring and ultrasonic atomization at first to form filler emulsion, then the filler emulsion is sprayed out through high pressure of gas by a filler pre-dispersed material sudden-temperature breaking technology, and is sprayed to the surface of a high-temperature object, filler emulsion droplets are suddenly heated and broken, secondary dispersion of the filler in a rubber matrix is realized, then a high-temperature flashing drying technology is adopted, a wet-method rubber compound prepared by sudden-temperature breakage of the filler pre-dispersed material is placed in a high-temperature environment, water in the wet-method rubber compound is evaporated instantly, the cured filler is excellently dispersed in the rubber matrix, and finally, a filler / rubber composite material is prepared by the conventional internal mixer. The principle is scientific and reliable, the preparation method is practical, simple and convenient, the preparation efficiency is high, the application prospect is wide, and the use environment is friendly.

Description

Problems solved by technology

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art, solve the problem of carbon and carbon being difficult to disperse and easily agglomerate in the wet mixing process, and at the same time solve the problem of flocculation caused by adding acidic components in the wet mixing process. In order to solve the problems of poor material performance and other problems, a new wet mixing method and process was developed and designed. Through the sudden temperature crushing technology of carbon-carbon emulsion drop pre-dispersion, the uniform dispersion of carbon and carbon in the emulsion can be achieved, reaching the nano-scale of carbon and carbon. The degree of microscopic dispersion, through the high-temperature flash drying technology to achieve rapid drying of wet compound rubber, to prevent the microcosmic aggregation of carbon and carbon, thereby preparing high-performance wet compound rubber, providing high-performance rubber products for the preparation of high-performance tires and high-end rubber products. practical way
