Preparation method of novel inorganic fullerene nano silicone rubber material

Abstract

The invention relates to the technical field of preparation of rubber materials, and provides a preparation method of a novel inorganic fullerene nano silicone rubber material, which traces the source, fundamentally controls the performance of silicone rubber, presents the comprehensive characteristics of the novel inorganic fullerene nano silicone rubber material by strictly controlling each process, is suitable for application in more fields, and has wide application prospects. The preparation method mainly comprises the following steps: selecting raw rubber, metering, matching, stirring and mixing, mixing by an internal mixer, extruding by an extruder, calendering by a calender, carrying out multi-stage vulcanization processing and carrying out foaming forming processing, different raw rubber materials can be selected according to the use temperature requirement in the selection of the raw rubber, and the use temperature requirement is a silicone rubber product with the temperature of-70 to 250 DEG C; vinyl silicone rubber, a silicone rubber product with the use temperature requirement of-90-300 DEG C and low phenyl silicone rubber are adopted, when the product requires high and low temperature resistance and fuel oil or solvent resistance, fluorosilicone rubber is adopted, and an additive is added during metering, matching, stirring and mixing.

Description

technical field [0001] The invention relates to the technical field of preparation of rubber materials, in particular to a preparation method of a novel inorganic fullerene nano-silicon rubber material. Background technique [0002] As we all know, silicone rubber is a polymer elastic material with both inorganic and organic properties. Its molecular main chain is alternately composed of silicon atoms and oxygen atoms (-Si-O-Si-), and the side chains are connected with silicon atoms. Hydrocarbon or substituted hydrocarbon organic groups, such groups can be methyl, unsaturated vinyl (the mole fraction generally does not exceed 01005) or other organic groups. [0003] Silicone rubber was developed in the 1940s. The earliest researched variety abroad was dimethyl silicone rubber. It was put into production by DowCorning and General Electric in the United States around 1944. In the early 1960s, my country was successfully researched and put into industrial production. Now it pro...
