Abstract

The invention discloses a preparation technology of a silicone rubber glass fiber ceramic duct. The preparation technology comprises the following steps that (1) glass fibers are woven into a tubularduct blank; (2) the duct blank is dewaxed to obtain a base duct for standby use; (3) a silicone rubber mixture is prepared; (4) the silicone rubber mixture is prepared into a dissolution solution, thesurface of the base duct is dip-coated with the dissolution solution, and after dip-coating, a semi-finished duct material is obtained; (5) the semi-finished duct material is dried at the high temperature of 200-250 DEG C, and the silicone rubber glass fiber ceramic duct is obtained. According to the preparation technology, the adopted glass fibers are woven into the base duct, the fire resistance effect of the silicone rubber glass fiber ceramic duct can be effectively improved, then the base duct woven from the glass fibers is dip-coated with the silicone rubber mixture, and after dip-coating, a mixture coating is formed on the surface of the base duct; the mixture coating is mainly composed of silicone rubber and ceramic powder, and therefore the mixture coating has good fire resistance performance, heat resistance performance and insulation performance, and the fire resistance effect, heat resistance effect and insulation effect of the silicone rubber glass fiber ceramic duct arefurther improved.

Description

Technical field [0001] The invention belongs to the technical field of insulated conduits, and specifically relates to a preparation process of a silicon rubber glass fiber ceramic conduit. Background technique [0002] Most of the current silicone rubber insulated conduits are made by extrusion molding. The insulation and flame retardancy of the manufactured silicone rubber insulated conduits can only meet the general requirements for heat resistance, insulation and flame resistance. In fields where insulation and flame resistance are both high, the existing silicone rubber insulated conduits cannot meet the requirements. Therefore, there is an urgent need for an insulated conduit with high heat resistance, high insulation and high flame resistance. Summary of the invention [0003] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the prior art, and provide a process for preparing a silicon rubber glass fiber ceramic c...
