Fireproof plate

Abstract

The invention discloses a fireproof plate. A method for preparing the fireproof plate comprises the following steps of: 1, preparing high-efficiency fireproof glue; 2, preparing honeycomb type dense cells on a polystyrene plate; 3, squeezing the high-efficiency fireproof glue in the dense cells on the polystyrene plate in a high-pressure mode; 4, impregnating core paper by the high-efficiency fireproof glue, and drying and shaping the core paper to prepare the fireproof core paper for standby; 5, gluing the fireproof core paper on double sides of the polystyrene plate after fireproof treatment by the high-efficiency fireproof glue; 6, coating waterproof hardening glue on the surface of the fireproof plate; 7, pressing and shaping; 8, performing the negative pressure chemical reaction on the fireproof plate to remove aldehyde; and 9 detecting adhesiveness, smoothness, fireproof performance and residue substances such as formaldehyde of the product.

Description

technical field [0001] The invention relates to a fireproof board. Background technique [0002] In a broad sense, residential fireproof materials include partition materials, ceiling materials, furniture materials, floor materials, etc. Among them, the ceiling material and compartment material are quite important, but they are often overlooked by people. Most of today's residential buildings are high-rise collective housing. In order to reduce the load-bearing weight of high-rise buildings, the compartments are often designed with lightweight design. Most of them in foreign countries use polystyrene boards without flame-retardant treatment. The barbed wire layer is covered outside, and then the cement layer is sprayed on the outermost surface. Although this kind of compartment achieves the principle of light weight, the outer cement layer is prone to peeling off when exposed to high-temperature flames, and then melts the inner polystyrene board that has not been treated f...

Problems solved by technology

Although this kind of compartment achieves the principle of light weight, the outer cement layer is prone to peeling off when exposed to high-temperature flames, and then melts the inner polystyrene board that has not been treated for fire protection, making the fire resistance precarious

Compared with the non-fireproof and insufficient stability of the above partition materials, a kind of fireproof partition material used in residential buildings or other public buildings is to use light steel frame to build its structural frame, and then place it in the frame The body is filled with fire-proof and heat-insulating materials, and then gypsum boards are nailed on both sides. Although this structure has fire-proof and heat-insulating functions, its disadvantage is that it must be constructed on site depending on the space, so its construction is more time-consuming than commonly used partition materials. It also caused the high cost, so that the willingness of the consumers to undertake the installation has not been able to improve

Due to the troublesome installation and high cost of the existing partition materials, the residents are hesitant, and the improvement of the fireproof ability of the house is so urgent. Based on the manufacture and development of the relevant fireproof materials, the factory and the inventor therefore decided to Developed this type of fireproof board as a residential partition and ceiling material
