Abstract

The invention relates to a sound proofing and noise reducing damping coating and a production process thereof, and belongs to the technical field of chemical industry. The damping coating comprises the following raw materials in part by weight: 22 to 25 parts of acrylic emulsion, 15 to 20 parts of deionized water, 44.5 to 54.5 parts of silicate packing, 0.1 to 0.2 part of polysiloxane assistant, 0.5 to 0.8 part of sodium mercaptide assistant, 4.5 to 5 parts of antimonous oxide assistant, and 3 to 3.5 parts of chlorinated paraffin assistant. The damping coating has the advantages that: the sound proofing and noise reducing damping coating belongs to an environmental protection product without any solvent, and has good physical properties and chemical stability, good sound proofing damping performance, corrosion resistance, abrasion resistance, waterproofing, impact resistance, good adhesive force to steel, concrete and the like, quick curing and adjustable curing time; and the sound proofing and noise reducing damping coating can meet the requirements after once spraying, can be sprayed on any curved surfaces, inclined planes and special parts and cannot generate a phenomenon of sagging.

Description

technical field

[0001] The invention belongs to the technical field of chemical industry and relates to the improvement of a paint production technology. Background technique

[0002] With the development of modern industry and transportation, the problem of vibration and noise is becoming more and more serious. It endangers people's physical and mental health, affects the precision of mechanical products, and shortens the working life of machinery. The International Organization for Standardization and many countries have formulated and promulgated environmental sanitation standards for noisy operations to strictly control noise. No matter from prolonging the life of mechanical structure system or from protecting and improving people's living and working environment, vibration and noise have become a major issue that needs to be solved urgently.

[0003] The current civil and metal surface coatings do not have a unified standard for sound insulation and noise reduction, an...
