Problems solved by technology

However, once the waterproof and flame-retardant coating burns, as the heat transfers to the base layer, the base layer or the underlying structure will heat up, and the combustion will spread to the base layer and structure, resulting in structural failure.

Abstract

The invention belongs to the technical field of organic high-molecular composite materials and particularly relates to polymer-modified asphalt-based intumescent flame-retardant and waterproof coating and a preparation method. The technical scheme of the invention is as follows: the polymer-modified asphalt-based intumescent flame-retardant and waterproof coating comprises the following materials in parts by weight: 10-20 parts of modified polymer, 10-30 parts of petroleum asphalt, 4-10 parts of reinforced resin, 2-8 parts of plasticizing and softening agent, 60-80 parts of solvent, 10-15 parts of thermal expansion agent, 8-15 parts of dewatering and carbonizing agent, 10-20 parts of sintering carbon-forming agent and 15-30 parts of flame-retardant filler. By adoption of the technical scheme disclosed by the invention, a soft and compact hydrophobic coating layer can be formed, so that the sealing and waterproof performances are reliable.

Description

technical field [0001] The invention belongs to the technical field of organic polymer composite materials, and in particular relates to a polymer-modified asphalt-based intumescent fire-retardant waterproof coating and a preparation method thereof. Background technique [0002] Due to its excellent waterproof function and simple construction method, the application of organic polymer waterproof coatings has developed rapidly and can be applied to almost all waterproof projects. One of the most widely used types is polymer-modified asphalt-based waterproof coatings, which are especially suitable for use. It is suitable for the waterproof layer of the application part where the thickness is required to be large. The modified polymers of the existing polymer-modified asphalt waterproof coatings include polyurethane, SBS, styrene-butadiene rubber, neoprene, chlorinated rubber, perchlorethylene, etc., among which SBS and several rubbers have better adhesion. Low, the strength o...
