Problems solved by technology

These sound-absorbing panels are not easy to store, transport, and assemble due to size limitations, and some materials need additional protection and decorative layers on the surface
Moreover, the rock (mineral) wool material is harmful to the human body, and there is a risk of carcinogenesis if it is used improperly; the polystyrene foam sound-absorbing panel has poor air permeability and heat resistance, and will release harmful gases in case of fire; Permanent metal plate sound-absorbing materials and micro-perforated structure sound-absorbing panels are too expensive and have not been widely used
[0004] However, the currently published patented technology has the following problems: NRC is not high, and the sound insulation effect is limited; the flame retardancy of the product is not good; the adhesive emulsion emits irritating and harmful gases during the drying process, etc.
Patent CN1425720A (Application No. 03118445.6) discloses a sound-absorbing and environmentally friendly coating. The coating uses fly ash floating beads as light aggregates to improve the sound insulation effect. However, the pores of the fly ash floating beads are closed and impermeable, making the coating Poor sound insulation
Patent CN1429869A (Application No. 01145015.0) discloses a special flashing and sound-absorbing coating for concert halls, which adds light perlite and foam polystyrene particles to produce a certain sound-absorbing and sound-insulating effect; but its heat-insulating effect is relatively poor

Abstract

The invention discloses a heat-insulating sound-insulating coating used for an exterior wall of a residential house and a preparation method thereof. The coating is prepared from the following raw materials in parts by weight: 10 to 15 parts of a polymer emulsion, 5 to 10 parts of ethyl cellulose, 5 to 13 parts of waterborne amino resin, 6 to 9 parts of a benzoperoxide flame retardant, 4 to 7 parts of isocyanate, 5 to 9 parts of gypsum powder, 9 to 12 parts of basalt fiber, 13 to 18 parts of an inorganic heat-insulating filling material, 6 to 9 parts of a dispersant, 5 to 8 parts of an adhesive, 4 to 7 parts of polyvinyl alcohol, 7 to 9 parts of a flexibilizer, 5 to 8 parts of hollow nanometer silicon oxide, 6 to 10 parts of toluene diisocynate, 6 to 9 parts of a swelling agent and 26 to 39 parts of ionized water. According to the invention, components like styrene block copolymer resin, polyvinyl chloride resin, the basalt fiber and the hollow nanometer silicon oxide with good physical properties are compounded, and performances of the formula components are combined, so the heat-insulating sound-insulating coating has the advantages of good heat-insulating and damping effects, high sound-insulating performance, air-purifying and humidity-adjusting effects, and capability of adsorbing toxic and harmful gases in the air.

Description

technical field [0001] The invention relates to a heat-insulating and sound-insulating coating for residential exterior walls and a preparation method thereof. Background technique [0002] At present, the existing traditional sound insulation materials for residential exterior wall decoration are mainly made of glass fiber. Its disadvantages are that the glass fiber material has poor sound absorption effect at low frequencies, has no flame retardant effect, and cannot prevent mosquitoes. Harmful, it will produce harmful gas when burning. [0003] The noise pollution in modern society, especially the harm of indoor noise pollution to health and daily life has gradually attracted people's attention. Therefore, many modern residential exterior walls need to consider the internal sound insulation effect when designing. Sound insulation materials can not only improve the indoor sound quality environment, but also play a very important role in noise control. There are many kind...
