Abstract

The invention provides a high-crack-resistance damping coating. The high-crack-resistance damping coating comprises the following raw materials in parts by weight: 290 to 310 parts of an acrylic acid waterproof emulsion, 95 t 105 parts of an anti-rust emulsion, 45 to 55 parts of a plasticized acrylic acid emulsion, 13 to 17 parts of a film-forming aid, 90 to 110 parts of functional fillers and 45 to 55 parts of corrosion-resistant fillers. The damping coating has high flexibility, impact resistance and high stone crash resistance, and solves the problem that the profile 90-degree transitional coating is susceptible to cracking.

Description

technical field [0001] The invention belongs to the technical field of damping coatings, and in particular relates to a highly crack-resistant damping coating. Background technique [0002] At present, there are many types of damping coatings at home and abroad, but from the solvent of the coatings, there are mainly two types: solvent-based and water-based. Most of the former contain organic solvents and asphalt, which are highly toxic, highly volatile, pollute the environment, and have poor workability, so they are rarely used now. The latter damping coating uses water as a solvent, has low toxicity, low odor, low cost, easy construction, and environmental protection, and is the first choice for damping coatings for urban rail vehicles. [0003] my country has developed and produced damping coatings since the 1960s, and has formed a relatively mature development and production system so far, among which was authorized on May 13, 1998: Patent No. CN1039342C, the invention n...
