Sound insulation and noise reduction composite waved plate tile and production process thereof

Abstract

The invention discloses a sound insulation and noise reduction composite waved plate tile which is of a two-layer composite structure and comprises a PC layer and a sound absorption layer. The PC layer is prepared from the following raw materials in parts by weight: 60 to 70 parts of PC resin, 15 to 20 parts of polyacrylonitrile-butadiene-styrene copolymer, 0.8 to 1 part of an ultraviolet light absorber, 2 to 3 parts of a composite filler and 0.5 to 0.7 part of a compound flame retardant; thesound absorption layer is made of a polyurethane rigid foam material blended with modified expanded graphite; the invention further discloses a production process of the sound insulation and noise reduction composite waved plate tile. According to the sound insulation and noise reduction composite waved plate tile, the PC layer is prepared by takingPC resin as a polymer matrix, ABS copolymer is adopted for blending modification, the compound flame retardant and the composite filler are used as auxiliary materials, and the PC layer has good heat insulation, mechanical and sound insulation properties; the sound absorption layer has excellent sound-absorbing and sound-insulating effects and flame-retardant performance; the obtained sound insulation and noise reduction composite waved plate tile has good sound insulation, noise reduction and flame retardant properties, and is a high-performanceroof material product.

Description

technical field

[0001] The invention belongs to the field of corrugated boards, and in particular relates to a sound-insulating and noise-reducing composite corrugated board tile and a production process thereof. Background technique

[0002] The wave board is also called the tile board, and the traditional wave board includes asbestos tiles and glass steel tiles. In recent years, the production of asbestos tiles has attracted more and more attention due to the pollution to the environment and the harm to the health of workers, and many places are gradually closing down these asbestos tile manufacturers. However, due to the shortcomings of brittleness and poor tear resistance, FRP tiles cannot meet the actual needs of the market. On this basis, a kind of plastic corrugated board has emerged at the historic moment. Compared with asbestos tiles or fiberglass tiles, plastic corrugated panels have the characteristics of better strength, convenient construction, and better deco...
