Problems solved by technology

[0007] The present invention adopts 10-30 mesh mesh cloth as the base layer and the composite surface layer of ceramic fiber and ultrafine glass fiber to form a three-dimensional network structure, which improves the folding resistance of the material, enhances the strength of the material, and prolongs the service life of the material At the same time, it also effectively suppresses the deformation of the felt layer caused by the heavier grams; in the composite surface layer of ceramic fiber and ultrafine glass fiber, the amount of ceramic fiber is 55-100%, which increases the amount of ceramic fiber and improves the glass fiber. The problem of poor temperature resistance of fibers; at the same time, the use of ceramic fiber-based mesh cloth as the base cloth also enhances the temperature resistance of the material

Abstract

The invention relates to a composite ceramic fiber felt, a fireproof heat preservation and heat insulation material and an application thereofof the fireproof heat preservation and heat insulation material, which belongs to the technical field of fireproof materials. The invention provides a composite ceramic fiber felt. The fiber felt consists of a basic cloth layer and a surface layer, wherein the basic cloth layer is a 10-mesh to 30-mesh ceramic fiber grid cloth or ceramic fiber metal-wire twisted composite grid cloth, the surface layer is a ceramic fiber and glass fiber composite layer, and a consumption ratio of ceramic fibers to ultrafine glass fibers in the surface layer is (100 percent to 55 percent): (0 to 45 percent). The fireproof heat preservation and heat insulation material is formed by 2 to 4 composite ceramic fiber felt layers in a manner of alternately arranging the basic cloth layer and the surface layer. The fireproof grade of the fireproof heat preservation and heat insulation material reaches grade A1, the bending resistance is good, the fireproof time of a fireproof roller shutter door prepared from one layer of the fireproof heat preservation and heat insulation material reaches 3.8h, the fireproof grade reaches special grade TF3, and the fireproof heat preservation material can be used as a fireproof fabric of the fireproof roller shutter door.

Description

technical field [0001] The invention relates to a fireproof heat insulation material and its application, belonging to the technical field of fireproof materials. Background technique [0002] Ceramic fiber is a kind of fibrous lightweight refractory material, which has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and mechanical shock resistance. thermal performance. Glass fiber is a commonly used thermal insulation material at present. Compared with ceramic fiber, glass fiber is a medium and low temperature thermal insulation material with an applicable temperature below 700°C, while ceramic fiber is a high temperature thermal insulation material with a refractory temperature of 1000-1790°C. Ceramic fiber has a higher fire resistance. Glass fiber is good; however, ceramic fiber is not easy to comb and has poor linking performance. During the carding process of the product, there will be a...
