Abstract

The invention discloses a flame-retardant polyurea waterproof coating which is prepared from a prepolymer A and resin R, wherein the basic formula of the prepolymer A comprises 35-55% of N220, 40-55% of liquefied MDI and 15-10% of a liquid additive flame retardant 1; the basic formula of the resin R comprises 30-50% of N330, 10-30% of flame retardant resin, 5-20% of a liquid additive flame retardant 2, 15-25% of an amine chain extender, 3-10% of nano-aluminum trihydrate and nano-magnesium hydroxide, 3-5% of a catalyst, 3-5% of a coupling agent, 3-5% of a dispersant, 3-5% of a water absorbent, 3-5% of a defoamer, 3-5% of a light stabilizer and 3-5% of an ultraviolet light absorber. The coating disclosed by the invention is excellent in waterproof, corrosionproof and aging-resistant performances and fast setting and short in construction period.

Description

[0001] technical field [0002] The invention belongs to waterproof coatings, in particular to a flame-retardant polyurea waterproof coating. [0003] Background technique [0004] In recent years, due to frequent fire accidents caused by problems with exterior walls and roofing materials, it is imperative to improve the fire performance of building materials. The GB 8624 "Classification of Combustion Behavior of Building and Decoration Materials (Products)" standard currently being revised and the "Test Method for Combustion Performance of Roofing System Materials" standard under formulation intend to conduct combustion tests on roofing materials according to the system or product method, and stipulate relevant Judgments based. GB 8624 The relevant classification standards for roofing systems or products will be quoted in the revised GB 50016 "Code for Fire Protection Design of Buildings". Once the above standards are formally implemented, there will be rigid requirement...
