Problems solved by technology

At present, the improvement of the sound insulation performance of wall paint is mainly achieved by adding inorganic fillers. The porous adsorption properties of inorganic fillers are used to reduce the noise decibel level. Good, but the noise reduction and sound insulation effect is still not ideal

Abstract

The invention discloses soundproof wall paint. The soundproof wall paint is prepared from the following materials: polymer emulsions, composite fillers, flame retardants, mould inhibitors, dispersants, defoamers, thickeners and deionized water. Through special processing and preparing operations, the finally prepared wall paint has excellent soundproof property and is higher in temperature resistance, impact resistance and coating performance, high in comprehensive usage quality and high in market competitiveness.

Description

technical field [0001] The invention belongs to the technical field of paint processing, and in particular relates to a sound-insulating wall paint and a preparation method thereof. Background technique [0002] Coatings are materials that are coated on the surface of an object and can be well bonded to the base material and form a complete and tough protective film. Paint and paint are the same concept, and paint is a customary name that people have used for a long time. After being introduced into our country, it has been used in the construction industry. The role of coatings can be summarized into three aspects: protection, decoration, and special functions. The general composition of coatings is: including film-forming substances, solvents, additives, etc. [0003] Architectural coatings have the functions of decoration, protection and habitability improvement. The proportions of various functions vary depending on the purpose of use. Architectural coatings are call...
