Ceramic refractory cloth and preparation method thereof

Abstract

The invention provides a ceramic fire-resistant cloth, and relates to the technical field of fire-resistant materials, the ceramic fire-resistant cloth comprises a ceramic fire-resistant cloth body, the ceramic fire-resistant cloth body is formed by combining an ultra-thin glass fiber layer and a fireproof silicone rubber layer, the ultrathin glass fiber layer is prepared from the following components in parts by weight: 16-20 parts of glass fiber, 4-6 parts of a coupling agent, 10-13 parts of supplementary filler, 4-6 parts of defoaming powder and 4-6 parts of a waterborne polyurethane solvent, and the fireproof silicon rubber layer is prepared from the following components in parts by weight: 8-10 parts of an organosilicon polymer, 16-20 parts of a rubber raw material, 4-6 parts of a plasticizer and 10-13 parts of flame-retardant supplementary filler. The fireproof silicone rubber of the product is converted into a hard ceramic structure from an elastomer at high temperature or in flame, so that the fireproof silicone rubber has excellent fireproof, heat-insulating and insulating functions; the ultrathin glass fibers can greatly improve the mechanical properties of the fireproof silicone rubber, and improve the workability and convenient usability of the product.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a ceramic refractory cloth and a preparation method thereof. Background technique [0002] With the development of the production industry, it is necessary to use fire-resistant cloth to protect the required products in the production process of EV battery packs. Among them, fire-resistant cloth is used as a protective fabric for special industries and special types of work to flame-retardant products. There are many treatments to prevent burning or insulation, and the fireproof cloth is roughly divided into silicone rubber coated glass fiber cloth, basalt fiber fireproof cloth, acrylic cotton fiber fireproof cloth, Nomex fireproof cloth, SM fireproof cloth, blue glass fiber fireproof cloth , aluminum foil fireproof cloth, etc. However, the above-mentioned glass fiber cloth cannot be effectively protected in the environment of a relatively high fire source during use...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies of the prior art, the present invention provides a ceramic refractory cloth and its preparation method, which solves the problem that the above-mentioned glass fiber cloth cannot be effectively protected and treated under a relatively high fire source environment during use. And when it encounters a certain stability, the above-mentioned refractory cloth will have no thermal protection effect, which will cause damage to its products. If the product is a battery, it will also cause dangerous accidents such as explosions.
