Abstract

The invention relates to a preparation method for a rubber composite material, belonging to the field of material preparation. The preparation method is characterized by comprising the following steps: plasticating FKM on an open mill, and preparing an FKM rubber compound according to an FKM rubber compound formula; preparing a MVQ rubber compound according to an MVQ rubber compound formula; blending the MVQ rubber compound and the FKM rubber compound so as to prepare an MVQ / FKM blended rubber; mixing the MVQ / FKM blended rubber with a compounding agent, then mixing an obtained mixture with CFtreated with a silane coupling agent, and carrying out one-stage vulcanization and two-stage vulcanization so as to prepare a CF / MVQ / FKM composite material. According to the invention, the composite material is prepared by using the MVQ / FKM blended rubber as a base phase and CF as a reinforcing phase; chemical combination between the CF treated with the silane coupling agent and the MVQ / FKM blended rubber is generated; and the silane coupling agent exerts a bridge effect between the rubber and the CF, and the CF and the rubber are firmly connected together, so the comprehensive physical properties of the composite material are reinforced.

Description

technical field [0001] The invention belongs to the field of material preparation, in particular to a method for preparing rubber composite materials. Background technique [0002] With the development of the rubber industry, the application of rubber products is becoming more and more extensive. Fluorine rubber (FKM) has good high temperature resistance, corrosion resistance, cold resistance and air permeability, can be used for a long time at 200 °C, and has good insulation and flex resistance. It has become a modern industry, especially high Indispensable basic materials in the field of science and technology. However, FKM products have disadvantages such as poor wear resistance, low strength, and poor high and low temperature resistance, which seriously affect the service life. Silicone rubber (MVQ) has excellent cold resistance, heat resistance, ozone resistance and atmospheric aging resistance, and is in a semi-fluid state at room temperature, resulting in poor physi...
