Abstract

The invention discloses a sound absorption coating and a production method thereof. The sound absorption coating is prepared from the following raw materials: polyurethane, emulsion, slag wool fiber,water, a composite coupling agent, diatom ooze, expanded perlite, a levelling agent and a defoamer. The sound absorption coating has good sound absorption property; the coating is free of joints, highin decoration performance, excellent in hardness, finish degree, water resistance and cracking resistance, excellent in stability, and high in hardness; the mechanical property of the coating is enhanced; the usage performance of the coating is more excellent; the adhesion and the friction resistance of the coating are improved; the density and the strength of the coating are increased; the condition that the coating is pulverized, cracked and stripped after being constructed is avoided; the coating is non-toxic and harmless, is free of adverse effects on the human body and the environment, is applicable to reverberation control spaces such as theaters, lecture rooms, conference rooms, swimming pools and gymnasiums, is also applicable to sound improvement environments such as restaurants,dining rooms, offices, airport waiting halls, station waiting rooms, ship waiting rooms, shopping malls and exhibition halls, and can be used as a decorative sound absorption material applied to houses, villas, hotels, guesthouses and entertainment venues.

Description

technical field [0001] The invention relates to a building coating, in particular to a sound-absorbing coating and a production method. Background technique [0002] Driven by real estate, automobiles and ships, my country's coatings industry is growing day by day. As one of the important categories, architectural coatings have also achieved rapid development. Architectural coatings have the functions of decoration, protection and habitability improvement. Compared with decoration materials such as stone and ceramic tiles, they have obvious advantages in terms of energy consumption and cost. Therefore, in the field of interior and exterior wall decoration of buildings, the popularity of architectural coatings is gradually increasing. improve. The past 10 years have been called the "golden 10 years" of the real estate industry, and the paint industry has also taken the opportunity to achieve rapid development. At present, my country's paint industry has become the world's l...
