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...

AI Technical Summary

Problems solved by technology

Generally speaking, the adoption of various polystyrene heat preservation and heat insulation measures will increase the construction cost. At the same time, there are still some technical defects in the implementation of various measures. Among them, the problem of cracking on the surface of heat preservation and heat insulation layers has not been effective. Solved, which affects the decorative appearance and is the main obstacle to the promotion of this type of technology

In addition, although the government has issued various systems and regulations to strengthen the prevention and control of urban noise pollution, it is difficult to avoid various noises due to economic development and modern production and life, and the diseases caused by urban noise are on the rise.
