Problems solved by technology

[0014] In the above scheme, the purpose of stabilizing chloride ions and preventing the glass magnesium board from absorbing moisture and returning to halogen is achieved by reducing the content of magnesium chloride and combining stabilizers. Under the joint action of the glass magnesium board, the overall performance of the glass magnesium board is greatly improved, but because there is still magnesium chloride in the formula, it is impossible to fundamentally solve the situation of returning halogen and absorbing moisture, especially in the rainy season when the air humidity is high, returning halogen and absorbing moisture The situation is more significant

Embodiment 1

[0065] For the new anti-return halogen fireproof board, first mix the following raw materials by weight to obtain the fluid:

[0066] 7 parts of alum;

[0067] 20 parts of anhydrous magnesium sulfate;

[0068] 4.7 parts of trisodium phosphate;

[0069] 0.4 parts of fly ash;

[0070] 53 parts of water;

[0071] The obtained fluid is sequentially added to the following raw materials to form a slurry:

[0072] 55 parts of magnesium hydroxide, its magnesium content ≥ 85%, active magnesium > 65%;

[0073] 16 parts of woodworking powder, which is made by drying and refining pine wood;

[0074] 6.5 parts of straw;

[0075] Perlite 10 parts, fineness ≤ 45 mesh;

[0076] 3.8 parts of light calcium carbonate, fineness ≥ 400 mesh, whiteness ≥ 85;

[0077] Finally add 0.1 part of sodium fluorosilicate;

[0078] The obtained slurry and two layers of glass fiber mesh cloth are mechanically rolled, cut, and cured to obtain a finished product of 2440×1220×9 (mm). The specification of...

Embodiment 2

[0089] The difference between Embodiment 2 and Embodiment 1 of the new anti-halogen fireproof board is that the weight fraction of anhydrous magnesium sulfate is increased from 20 parts to 25 parts.

[0090] The prepared product is sent to the National Building Materials Industry Wall Roofing Material Quality Supervision, Inspection and Testing Center for testing, and the results are as follows:

[0091] Anti-halogenation: no water drops, no moisture return, in line with JC688-2006 standard;

[0092] Factory moisture content: 5%, better than the highest standard value of JC688-2006 8%;

[0093] The screw holding force is 30N / m, which is better than the minimum standard value of 20N / m in JC688-2006;

[0094] Chloride ion content 0%, better than the highest standard value of JC688-2006;

[0095] Non-flammability: meet the requirements of Class A in GB8624-1997.

Embodiment 3

[0097] The difference between the third embodiment and the first embodiment of the new anti-halogen fireproof board is that the weight fraction of anhydrous magnesium sulfate is increased from 20 parts to 28 parts.

[0098] The prepared product is sent to the National Building Materials Industry Wall Roofing Material Quality Supervision, Inspection and Testing Center for testing, and the results are as follows:

[0099] Anti-halogenation: no water drops, no moisture return, in line with JC688-2006 standard;

[0100] Factory moisture content: 5%, better than the highest standard value of JC688-2006 8%;

[0101] The screw holding force is 30N / m, which is better than the minimum standard value of 20N / m in JC688-2006;

[0102] Chloride ion content 0%, better than the highest standard value of JC688-2006;

[0103] Non-flammability: meet the requirements of Class A in GB8624-1997.

Abstract

The invention discloses a novel halogenide-resistant and fireproof plate. The novel halogenide-resistant and fireproof plate aims at solving the problem of no fundamental solving of the halogenide moisture absorption condition due to the existence of magnesium chloride in a formula, especially the severe halogenide moisture absorption condition in plum rain seasons having a large air humidity. The novel halogenide-resistant and fireproof plate comprises a forming agent, a reinforcing material, a lightweight filler, a modifier and water, wherein the forming agent includes alum, magnesium hydroxide and sodium fluorosilicate, the reinforcing material is a glass fiber gridding cloth or other reinforcing materials, and the modifier includes a brightener, a stabilizer and a color toner. No magnesium chloride is used in the invention, so the halogenide phenomenon is thoroughly solved, and people's demands are met.

Description

technical field [0001] The invention relates to the field of fireproof boards, more specifically, it relates to a novel anti-return halogen fireproof board. Background technique [0002] Glass magnesium fireproof board is one of the most widely used fireproof boards at present. It is a new type of non-combustible building compounded with magnesite cementitious material as base material, medium alkali glass fiber cloth as reinforcement material and light material as filler. sheet. It can be used as thermal insulation building wall panels, door core panels, ceiling panels, packing boxes, etc., and can replace wooden plywood to make dado, door and window frames, furniture, etc. It can also be painted with blending paint and clear water paint according to needs, and can be processed into various types of board surfaces. It can also be used in simple fire protection projects in damp environments such as basements and mines. [0003] In the prior art, the magnesia cementitious ...
