Efficient fireproofing sealant for constructions

Abstract

The invention provides efficient fireproofing sealant for constructions. The sealant is prepared from the following raw materials in parts by weight: 2-4 parts of allyl alcohol, 0.8-2.3 parts of stearic acid, 0.5-1.5 parts of diacetyl peroxide, 0.6-1.2 parts of an anti-aging agent, 8-16 parts of rutile titanium dioxide, 4-7 parts of ground calcium carbonate, 1-3 parts of sodium hexametaphosphate, 6-12 parts of a thickening agent, 10-16 parts of rutile titanium dioxide, 18-35 parts of polyacrylic emulsion resin, 7-14 parts of flexibilizer, 2-4 parts of a thixotropic agent, 3-8 parts of nitrile rubber, 1-4 parts of illite powder, 1-2 parts of bamboo charcoal fibers and 4-7 parts of nano-calcium carbonate. The efficient fireproofing sealant has the beneficial effects of excellent elasticity, abrasion resistance, good flame-retardant and fireproofing performance, small corrosion for matrix, excellent adhesion and no pollution.

Description

technical field [0001] The invention relates to a high-efficiency fireproof sealant for buildings. Background technique [0002] The sealant is a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of cohesion. It is an adhesive used to fill the gaps in the configuration to play a sealing role. Due to the building structure or the exterior walls of important high-rise and super high-rise buildings, the fire risk is relatively high, especially the fire protection requirements for large public buildings with dense crowds are getting higher and higher, and the fire protection requirements of buildings are directly related to the safety of people and property. . However, in some special occasions of construction, it is also required to have excellent fireproof ability, but the existing fireproof function is not good, and the adhesion needs to be improved.
