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
However, the current NRC of sound insulation coatings 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.
At the same time, due to the closed and impermeable pores of the fly ash floating beads, the sound insulation effect of the coating is not ideal
And it will release poisonous gas in case of fire, so the coating has potential safety hazards

Abstract

The invention discloses a sound-insulation coating and a preparation process thereof. The sound-insulation coating is prepared from the following raw materials: glycerol, a catalyst, a nonionic chainextender, an ionic chain extender, a neutralizer, a silane coupling agent, a silica powder, bentonite, a dispersant, carbonized fibers, foam polystyrene, isocyanate, titanium oxide, a polyacrylamide solution, a thickener, an acrylic emulsion, bamboo charcoal, a flame retardant, a wetting agent, a ceramic powder, a toughening agent, a cleaning agent, a puffing agent and water. The preparation method comprises the steps of preparing a component A, preparing a component B and mixing to prepare the coating. The prepared sound-insulation coating has the thermal insulation and sound insulation properties improved by addition of the silica powder and the carbonized fiber, has the advantages of good comprehensive application performance, reasonable components and low cost, has the abilities of sound insulation and sound absorption, is not easy to volatilize in a hot environment, has small harm to human bodies, and is suitable for use in various public occasions; and the preparation method is scientific and reasonable.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a sound-insulating coating and a preparation process thereof. Background technique [0002] The sound absorption, appearance, and mechanical properties of the sound-proof coating are suitable for the ceiling of the hall with a large indoor surface and a high roof and walls above a certain height. Such as the sound absorption treatment of indoor ceiling parts such as theaters, conference venues, shopping malls, and corridors. Sound-absorbing coatings are most suitable for places with strong decoration and sound absorption; at the same time, 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 Buildings need to be designed with sound insulation in mind. Sound insulation materials can not only improve the indoor sound quality environment, but also play a ve...
