Abstract

The invention provides non-combustible grade damping paint. The paint comprises, by weight, 290-310 parts of acrylic acid waterproof emulsion, 95-105 parts of anti-rust emulsion, 45-55 parts of plasticization acrylic acid emulsion, 45-55 parts of pure acrylic emulsion, 13-17 parts of a coalescing agent, 285-315 parts of functional filler, 195-205 parts of fire retardant and 45-55 parts of anti-corrosive filler. The damping paint solves the problems that existing damping paint is low in flame retardancy, and potential fire hazards exist, has a wide temperature range and is low in compound damping factor.

Description

technical field [0001] The invention belongs to the technical field of damping coatings, in particular to a non-combustible damping coating. Background technique [0002] Water-based damping coatings mainly use water as a dispersant, have low VOC, and are environmentally friendly, and are gradually replacing traditional organic solvent-based damping coatings and asphalt-type damping sheets. At the same time, due to the characteristics of its coating, it can be easily coated on more complex interfaces without cutting. Therefore, it has more advantages in construction than the traditional butyl rubber type damping film. Due to some disadvantages of water-based damping coatings, their wider application is also limited. [0003] Traditional water-based damping coatings dry slowly, affecting construction progress. In terms of quick-drying water-based damping coatings, the published Chinese patent CN102850888A adopts the method of A and B two-component emulsion to improve the c...
