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 an

Embodiment 1

[0017] Depend on figure 1 It can be seen that the production and preparation process of the fireproof board of the present invention includes: preparation of the fireproof core paper and processing of the polystyrene board, and then pasting the fireproof core paper on both sides of the treated polystyrene board, pressing dry, and setting the shape , carry out negative pressure chemical reaction aldehyde removal treatment on the fireproof board, and then carry out the inspection of product adhesion, flatness, fire resistance, and residual formaldehyde harmful substances, and then put it into the warehouse for storage. After that, it is provisioned to users on demand.

[0018] The specific structure of the fireproof board of the present invention is as follows: figure 2 As shown, the fireproof board of the present invention is pasted with fireproof core paper on the upper and lower two ends of the modified flame-retardant polystyrene board 1 . The contact surface between the ...

Embodiment 2

[0021] The preparation of the fireproof board has the following steps: 1. Make high-efficiency fireproof glue; 2. Make honeycomb dense cells on the polystyrene board (such as figure 2 (shown) the residue in the aperture must be cleaned, so that the high-efficiency fireproof glue can be squeezed in smoothly and reach the standard content; 3. Use high pressure to squeeze the high-efficiency fireproof glue into the dense nest holes on the polystyrene board; 4. Use high-efficiency fireproof glue to impregnate the core paper, dry and set it to make fireproof core paper, and set aside; 5. Use high-efficiency fireproof glue to seal the fireproof core paper figure 2 The shown fireproof core paper A side) is pasted on both sides of the polystyrene board that has been treated with fireproofing; 6. The surface of the fireproof board (such as figure 2 Surface B of the fireproof core paper shown) is coated with waterproof hardening glue; 7. Carry out pressure drying and shaping; 8. Perf...

Embodiment 3

[0025] The preparation steps of the high-efficiency fireproof adhesive are as follows: firstly, put the melamine resin base material into the reaction kettle, heat, stir, and raise the temperature to 86.5 degrees Celsius, add the phosphorus nitrogen flame retardant resin base material, keep the heat for 90 minutes, and vacuum the temperature to 86.5 degrees Celsius. Drop to 70 degrees Celsius, start cooling, add 5% smoke suppressant and 5% foaming agent at 55 degrees Celsius, add carbohydrates and soluble starch at 50 degrees Celsius, continue stirring to 35 degrees, add inorganic powder and pass through the colloid mill. into high-efficiency fireproof glue, and then discharged.

[0026] Preparation of fireproof core paper: impregnate the core paper with high-efficiency fireproof glue, and dry it at 60 degrees Celsius for 45 minutes to set it up for later use.

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...
