Warm sound-proof decorative materials and prepn. method

Abstract

This invention is attributed to the field of building materials, concretely speaking, relates to a kind of decoration materials with heat preservation and sound absorption functions and its preparation method. The heat-preserving and sound-absorbing decoration materials comprise a hear-preserving layer, a decoration layer and a mask layer. The heat-preserving layer is made of polybenzene particles, water glass, cement, silica fume, slag powders, fly ash and sand. The decoration layer is made of polybenzene, rubber powders, pigment, cement, silica fume, slag powders and sand. The mask layer is made of organosilicon series of waterproof materials. By the technique of spray stir, layered moulding, compression molding and vapor conservation, the polybenzene particles and the porous structure can help realize highly effective heat preservation. The sound-absorbing structure can be fabricated by compression molding. Fascinating stereo patterns can be organized by alternation of mould shape and pigment. Besides, thanks to the mask layer, wear and decoration properties can be promoted. The product performs excellent heat-preserving, sound-absorbing and decorative functions.

Description

technical field

[0001] The invention belongs to the technical field of building materials, and in particular relates to a heat-preserving and sound-absorbing decorative material of multifunctional building materials and a preparation method thereof. Background technique

[0002] At present, the area of ​​houses built in my country every year reaches 1.6 billion to 2 billion square meters 2 , but more than 95% of new buildings are still high-energy buildings. The energy consumption of heating or cooling per unit building area is about three times that of developed countries with similar climates. my country's building energy consumption has accounted for nearly 30% of the country's energy consumption. If the building The level of energy consumption remains the same. By 2020, building energy consumption will reach 1.089 billion tons of standard coal, and the peak load of air conditioners alone will be equivalent to the full-load power generation of 10 Three Gorges Power Station...
