Problems solved by technology

[0002] The existing foamed cement door core board has the advantages of high compressive strength, low cost, no brine return, no softening, no water absorption, no deformation, and good fireproof effect compared with other fireproof material door core boards. Porosity increases and decreases, the more foam is introduced, the greater the porosity, the smaller the bulk density, the more obvious its light weight, thermal insulation, and sound insulation performance, but the greater the decline in strength, so the existing foamed cement door The core board generally has the disadvantages of high brittleness and easy fracture

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] refer to figure 1 , figure 2 , the overall appearance of the porcelain type fire door core board of the present invention is a cuboid, the middle layer is a foamed cement substrate (1), and a reinforcement layer (2) is arranged on both sides of the foamed cement substrate (1), and the reinforcement layer (2 ) is the mesh bar plus non-fired ceramic covering, and the mesh bar is preferably made of mesh cloth.

[0012] Because the mesh cloth has the characteristics of high strength and light weight, and it can be well combined with the non-fired ceramic cladding material, and forms a firm composite structure board with the foamed cement substrate, so it has advantages over other existing types. Fire door core panels have more and better excellent performance.

[0013] refer to image 3 , The core plate of the porcelain type fireproof door of the present invent...

Abstract

A ceramic core board of a fireproof door comprises a base board, wherein the base board is a foaming cement base board, reinforcing layers are arranged on two sides of the foaming cement base board and are formed by mesh reinforcement and burn-free ceramic coverings, and the mesh reinforcement is gridding cloth. The ceramic core board of the fireproof door has the advantages of light weight, high strength, waterproofing, fireproofing, small heat conductivity coefficient, no deformation, no efflorescence, good sound insulation effect, low cost and the like and is an upgrade product of an existing core board of the fireproof door.

Description

technical field [0001] The invention relates to the technical field of composite boards, in particular to a porcelain type fire door core board. Background technique [0002] The existing foamed cement door core board has the advantages of high compressive strength, low cost, no brine return, no softening, no water absorption, no deformation, and good fireproof effect compared with other fireproof material door core boards. Porosity increases and decreases, the more foam is introduced, the greater the porosity, the smaller the bulk density, the more obvious its light weight, thermal insulation, and sound insulation performance, but the greater the decline in strength, so the existing foamed cement door The core board generally has the disadvantages of high brittleness and easy fracture. Contents of the invention [0003] In order to solve the above-mentioned shortcomings of the existing foamed cement door core board, the object of the present invention is to provide a hig...
