Problems solved by technology

Because the composite belt described in this utility model uses high-temperature glass fiber cloth as a reinforcing layer, its tensile performance is poor, and its anti-puncture performance is not ideal. After burning at high temperature, the glass fiber cloth becomes brittle and brittle, which will affect the overall crust of the composite belt. Performance, resulting in the ceramic-like shell after burning is fragile and easy to fall off
In addition, there are fine plush fibers in glass fiber cloth, and the production and users will feel uncomfortable when touching the glass fiber plush skin

Abstract

The invention discloses ceramic fireproof and fire-resistant silicone rubber, a method for preparing the same, a ceramic compound belt with the ceramic fireproof and fire-resistant silicone rubber and a method for preparing the ceramic compound belt, and belongs to the technical field of ceramic compound belts. The ceramic fireproof and fire-resistant silicone rubber is made of, by weight, 100 parts of silicone rubber, 20-70 parts of silicon dioxide, 1-15 parts of dimethyldiethoxysilane, 20-60 parts of ceramic powder, 1-5 parts of stearic acid, 20-100 parts of flame retardants, 1-30 parts of magnesium oxide, 20-60 parts of magnesium hydroxide and 0.5-5 parts of silane coupling agents. The ceramic fireproof and fire-resistant silicone rubber and polyimide rubber belts are vulcanized and compounded with one another to obtain the ceramic compound belt with high breakdown resistance and fireproof and fire-resistant performance. The ceramic fireproof and fire-resistant silicone rubber, the methods and the ceramic compound belt have the advantages that the ceramic compound belt is excellent in breakdown-resistant performance, good in fireproof and fire-resistant performance and convenient to wind and coat, and has certain tensile properties.

Description

technical field [0001] The invention relates to ceramicized fireproof and refractory silicone rubber, a preparation method, a ceramicized composite belt having the same and a preparation method, and belongs to the technical field of ceramicized composite belts. Background technique [0002] The existing ceramicized fireproof and refractory composite belts are generally prepared by using ceramicized fireproof and refractory silicone rubber as the ceramicized silicone rubber layer and fireproof glass fiber cloth as the reinforcing layer. For example, "A Ceramic Fireproof and Refractory Composite Belt" with the Chinese utility model patent authorization announcement number CN202454356U discloses a ceramic fireproof and refractory composite belt, including two reinforcing layers and ceramic silicon between the two reinforcing layers. The rubber layer and the reinforcing layer are glass fiber cloth. The vitrified silicone rubber layer is made of silicone rubber, silicon dioxide,...
