Problems solved by technology

However, the compatibility of flame retardants and matrix resins is usually poor, which leads to poor dispersion of flame retardants in rubber asphalt emulsions, which affects the amount of flame retardants added and the flame retardant effect.
Therefore, the flame retardant effect of rubber asphalt waterproof coating needs to be further improved

Abstract

The invention relates to a flame-retardant waterproof coating sprayed with quick-setting rubber asphalt and a preparation method of the flame-retardant waterproof coating, and belongs to the technicalfield of waterproof coatings. The waterproof coating includes a component A and a component B, the component A is prepared from the components in parts by weight: matrix asphalt, an anionic emulsifier, water, a high-molecular polymer rubber latex, a silicate stabilizer, polyvinyl alcohol and a fire retardant, and the component B is prepared from the components in parts by weight: a curing agent and water. The preparation method includes the steps that the matrix asphalt is heated, the high-molecular polymer rubber latex is added for swelling, then an anionic emulsifier aqueous solution is added, then the mixture is heated, a colloid mill is used for grinding, then the mixture is heated and stirred, the temperature is lowered, and the silicate stabilizer, the polyvinyl alcohol and the fireretardant are added for mixing to prepare the component A; and the curing agent and the water are mixed to prepare the component B, and the component A and the component B are mixed to prepare the flame-retardant waterproof coating sprayed with the quick-setting rubber asphalt. The waterproof coating has the excellent flame retardant performance.

Description

technical field [0001] The invention relates to the technical field of waterproof coatings, more specifically, it relates to a spray-coated quick-setting rubber asphalt flame-retardant waterproof coating and a preparation method thereof. Background technique [0002] The quality of building waterproofing projects directly affects the normal use and life of buildings and structures, and waterproof materials are an important factor affecting waterproofing projects. Among them, rubber asphalt waterproof coatings are widely used in waterproof construction in my country due to the advantages of wide source of raw materials, low cost, fast construction and excellent waterproof effect, such as housing construction, pipe corridors, subway tunnels and other areas. However, because the rubber asphalt waterproof coating is a flammable material, it cannot meet the fire protection requirements of some special buildings such as wooden buildings, so its application range is limited. At th...
