Problems solved by technology

[0003] Among the existing external wall insulation materials, polystyrene board occupies a high market proportion due to its low thermal conductivity, good acid and alkali corrosion resistance, unfavorable warping, and easy production. Because the material is a flammable material, it is flammable in case of fire. When a fire occurs, the flame spreads quickly, accompanied by a large amount of molten droplets, smoke and harmful gases, which not only pollutes the environment, but also causes certain harm to people's daily life. hazards, so the existing technology is to modify the polystyrene board, in order to overcome the traditional polystyrene board is flammable, shrinkage when burning, melting, dripping and other shortcomings
[0004] In the prior art, the patent CN104031325B "polystyrene foam board, its production method and its curing agent" discloses a biomass-modified polystyrene foam board and its preparation method, and its preparation raw materials include expandable Polystyrene particles, thermosetting resin, curing agent, and flame retardant. The thermosetting resin is a biomass-modified furan resin, mainly made of formaldehyde, urea, furfuryl alcohol, and lignin. The production process is complicated and inconvenient. Workers operate, and there is a certain degree of instability in the production process, which is not conducive to the use of this method in mass production of modified polystyrene boards
[0005] The polystyrene board products currently produced all have a certain degree of production defects. Therefore, how to produce and develop a new type of polystyrene board to make it more excellent in performance and more stable in production is a difficult problem that needs to be solved urgently.

Abstract

The invention relates to an organically modified polystyrene board and a preparation method thereof. Raw materials comprising expandable polystyrene, magnesium oxide, magnesium chloride, a reinforcingagent, a curing agent, an efflorescence agent and a color paste undergo the steps of weighing according to a formula, color paste mixing, pre-expansion, molding, fireproof curing enhancement solutionpreparation, adsorption and high-temperature maintenance to prepare the organically modified polystyrene board. The novel fireproof curing enhancement solution is used to improve the toughness of themodified polystyrene board and the flame retardant property and the board strength of the product, so the advantages of small heat conduction coefficient and high heat storage coefficient of traditional polystyrene foam boards are reserved, the heat insulation and energy saving effects of the modified polystyrene board is better than that of common modified polystyrene boards, the inflammable disadvantage of the traditional polystyrene boards is overcome, and the modified polystyrene board has a high safety performance, and reaches the prescribed class A fireproof standards of heat insulationmaterials; and the preparation method is mature, is easy for workers to construct, is safe and reliable, and avoids the system instability defect of other novel materials.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an organically modified polystyrene board and a preparation method thereof. Background technique [0002] The full name of polystyrene board refers to polystyrene foam board. Polystyrene board is mainly made of expandable polystyrene beads. of a white solid. [0003] Among the existing external wall insulation materials, polystyrene board occupies a high market proportion due to its low thermal conductivity, good acid and alkali corrosion resistance, unfavorable warping, and easy production. Because the material is a flammable material, it is flammable in case of fire. When a fire occurs, the flame spreads quickly, accompanied by a large amount of molten droplets, smoke and harmful gases, which not only pollutes the environment, but also causes certain harm to people's daily life. Therefore, the prior art has modified polystyrene boards to overcome the shortcomings of traditio...
