Problems solved by technology

[0003] Since a certain amount of sodium chloride inevitably remains in the raw material of magnesium chloride, the perlite flame-retardant board made will return to moisture when it encounters rainy weather, causing water droplets to overflow from the nail holes of the wooden door, and the door will be damp. Afterwards, distortion and deformation occur, the surface of the plywood becomes discolored due to damp, and the plywood cannot be bonded with the perlite flame-

Embodiment 1

[0026] The composition weight ratio of the auxiliary filler is: 15kg of the expanded perlite, 32kg of magnesium chloride, 18kg of magnesium oxide, 250ml of phosphoric acid solution, 18kg of talcum powder, 1kg of emulsifier, 88kg of binder, 4kg of ferrous sulfate solution, organic silicon Waterproof agent 28kg.

[0027] The ferrous sulfate solution is uniformly mixed with 1kg of ferrous sulfate and 3kg of water.

[0028] The preparation method of perlite flame retardant board comprises the following steps:

[0029] 1) According to the composition and weight ratio of the flame retardant layer, expand perlite 15kg, magnesium chloride 32kg, magnesium oxide 18kg, phosphoric acid solution 250ml, talcum powder 18kg, emulsifier 1kg, binder 88kg, ferrous sulfate solution 4kg, organic 28kg of silicon waterproofing agent is prepared.

[0030] 2) Take 18kg of magnesium chloride in step 1 and use water to make magnesium chloride into a liquid with a density of 23%.

[0031] 3) Mix the l...

Abstract

The invention discloses a perlite flame-retardant plate and a preparing method of the perlite flame-retardant plate. The perlite flame-retardant plate comprises a door leaf door core and auxiliary packing, wherein the auxiliary packing is placed in the door leaf door core and consists of the following ingredients in proportioning by weight: 10 to 20kg of expanded perlite, 26 to 39kg of magnesium chloride, 11 to 24kg of magnesium oxide, 200 to 300ml of phosphoric acid solutions with the concentration of 5 percent, 15 to 20kg of talcum powder, 0.1 to 2.0kg of emulsifying agents, 51 to 115kg of bonding agents, 4kg of a ferrous sulfate solution and 25 to 30kg of waterproof agents. The perlite flame-retardant plate has the advantages that flame-retardant and heat-insulation properties and non-toxicity are achieved; the flexural and compressive strength is high; aging is avoided; and the hydrophobicity under the high-humidity condition is high, so the perlite flame-retardant plate does not get damp.

Description

technical field [0001] The invention relates to a method for manufacturing a flame-retardant board, more specifically, it relates to a perlite flame-retardant board and a preparation method thereof. Background technique [0002] The fire protection of wooden materials has always been an important topic in the field of construction. In recent years, although different types of fireproof boards, fireproof doors and other fireproof products have appeared, some of these products do not meet the fireproof requirements and cannot solve the actual problem of fireproofing. Some consume a lot of high-quality wood, and some It is the treatment of the material. Once it is not handled properly, it will cause pests, especially some of the adhesives in it can not meet the requirements of environmental protection and safety performance, which will pollute the environment. [0003] Since a certain amount of sodium chloride inevitably remains in the raw material of magnesium chloride, the p...
