Fireproof material for protective building materials and preparation method thereof

Abstract

The invention discloses a fireproof material for protective building materials and a preparation method thereof. The fireproof material is processed and prepared from the following raw materials in parts by weight: 0.3-0.8 parts of modified airgel, 20-40 parts of magnesium oxide, and 8 parts of calcium carbonate powder -12 parts, 0.2-0.5 parts of mortar concrete fiber, 0.5-2 parts of redispersible latex powder, 25-30 parts of magnesium sulfate solution, 2-6 parts of photocurable resin; Processing, avoiding a large amount of air mixing, so that the slurry is quickly leveled, and by adding light-curable resin into the slurry as a raw material, after the slurry in the mold is leveled and defoamed, the slurry is sent to the preliminary setting device through the conveyor belt , through the ultraviolet LED lamp to emit ultraviolet light to promote the curing of the slurry, so that the surface of the slurry in the mold has a certain strength and will not be deformed due to transfer, thus facilitating the batch transfer of the mold and the maintenance and shaping of the slurry, so that the slurry The places for pouring and maintenance can be separated, which is conducive to the high efficiency of industrial production.

Description

Technical field [0001] The present invention belongs to the technical field of building materials, and in particular, a fire prevention material for protective material and its preparation method thereof. Background technique [0002] Because of the frequent building fire, people are more concerned about the fire prevention performance of building materials, especially many insulation materials have flammable, combustion, produce toxic gases, when practical, combustion, and toxic gas, affect construction safety Therefore, in the prior art, while ensuring the insulation performance of the material, the fire prevention performance of the material is required. [0003] However, in order to ensure the nature of fireproof, many fire prevention materials have a large density, which limits the range of fire prevention materials, and during the drying of fire prevention, the anti-shrinkage is affected, and the molding fire prevention material is prone to cracking phenomenon, which seriou...

Problems solved by technology

[0002] Due to the frequent occurrence of building fires, people pay more attention to the fire performance of building materials. In particular, many insulation materials are flammable and produce toxic gases when burned. In actual use, they burn and produce toxic gases, which affect building safety. , so in the prior art, while ensuring the thermal insulation performance of the material, it is also necessary to improve the fireproof performance of the material

[0003] However, in order to ensure fireproof properties, many fireproof materials have relatively high density, which will limit the scope of use of fireproof materials. The quality of molded products; in the process of producing fireproof boards with slurry raw materials, due to the fluidity of the slurry, it is necessary to avoid moving the mold after adding the raw materials into the mold, so as to avoid the appearance of the product after curing and setting due to the shaking of the slurry Deformation, but this will greatly increase the difficulty of production, resulting in restrictions on the site for pouring raw materials and curing and shaping, and also directly increases the difficulty of pouring slurry. In order to solve the above problems, the present invention provides the following technical solutions
