Heat and sound insulation material and preparation method thereof

Abstract

The invention discloses a heat and sound insulation material and a preparation method thereof. The coating in the heat and sound insulation material is prepared from the following materials in parts by weight: 10 to 15 parts of carboxylic styrene-butadiene latex, 12 to 20 parts of amorphous Alpha-olefin polymer, 5 to 13 parts of alkyd resin, 6 to 9 parts of benzoyl peroxide flame retardant, 14 to22 parts of ethylene-vinyl acetate copolymer, 5 to 9 parts of vinyl acetate, 9 to 12 parts of ethylene-butylene copolymer, 22 to 28 parts of polyacrylamide, 6 to 9 parts of dispersant, 5 to 8 parts ofbinder, 4 to 7 parts of silicate mineral, 7 to 9 parts of toughening agent, 5 to 8 parts of hollow nano-silica, 6 to 10 parts of nano-graphene, 6 to 9 parts of swelling agent and 26 to 39 parts of ionized water. According to the invention, the amorphous Alpha-olefin polymer, the polyacrylamide resin, the alkyd resin, polyacrylamide, nano-graphene and the like with good physical properties are integrated for compounding, the coating has good heat insulation, sound insulation and damping effects, can also achieve the objective of energy saving and environment protection, meets the requirement of energy saving and environment protection, and has high economic benefit.

Description

technical field [0001] The invention relates to a heat-insulating and sound-insulating material and a preparation method thereof. Background technique [0002] At present, the existing traditional sound insulation materials for architectural 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, cannot prevent mosquitoes, and not only the material itself is harmful to the human body, It also produces harmful gases during combustion. [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 buildings need to consider their 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 kin...

AI Technical Summary

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
