Problems solved by technology

Another example is the Chinese patent CN101405353B, which uses latex particles whose gel ratio is controlled within a specific range to produce baked and dried water-based damping coatings, which are basically free of defects, but have higher requirements for emulsions.
Moreover, these traditional water-based damping coatings have poor impact resistance and low strength.

Abstract

The invention provides high-strength damping paint. The high-strength damping paint comprises raw materials in parts by weight as follows: 145-155 parts of vinyl acetate-ethylene copolymer emulsion, 145-155 parts of waterproof acrylic acid emulsion, 145-155 parts of pure acrylic emulsion, 195-205 parts of a flame retardant, 4-6 parts of a defoamer and 195-205 parts of functional filler. The high-strength damping paint is good in impact resistance, adhesion and flexibility.

Description

Technical field [0001] The invention belongs to the technical field of damping paint, and specifically relates to a high-strength damping paint. Background technique [0002] Because water-based damping coatings mainly use water as a dispersant, they have low VOC and are green and environmentally friendly, and are now gradually replacing traditional organic solvent-based damping coatings and asphalt-based damping sheets. At the same time, due to the characteristics of the coating, it can be easily coated on more complex interfaces without cutting. Therefore, it has more advantages in construction than the traditional butyl rubber damping film. Due to the disadvantages of water-based damping coatings, their wider applications are also limited. [0003] Traditional water-based damping coatings dry slowly, which affects the construction progress. In terms of fast-drying water-based damping coatings, the published Chinese patent CN102850888A uses A and B two-component emulsions to i...
