Manufacturing process of novel environment-friendly sound-insulating plate

Abstract

Disclosed is a manufacturing process of a novel environment-friendly sound-insulating plate. The manufacturing process comprises the following steps that 1, after fly ash, glazed hollow beads, water, light-burned magnesium oxide, anti-crack and anti-leakage agents, a tackifying agent, Kaolinite powder and lime putty powder are fully and evenly mixed and stirred, sawdust powder is added, secondary stirring is conducted, and a first mixture is obtained; 2, the first mixture is poured into a mould, the mould is filled, the first mixture is flatly laid, the mould with the first mixture is put into a high-temperature sintering furnace to be sintered, and a base material plate is obtained after sintering; 3, magnesium chloride brine and talc powder are mixed, a pulp material is obtained after uniform stirring, the pulp material is poured on glass-fiber cloth, drying treatment is conducted in a high-temperature and high-pressure environment, and a film material is obtained; 4, the base material plate is wrapped with the film material, high-temperature and high-pressure compression molding is conducted, decorating, grinding and polishing are conducted after compression molding, and a product is obtained. The novel environment-friendly sound-insulating plate has good heat insulation property, sound insulation property and water-proof performance, materials are environmentally friendly and save energy, and the cost is low.

Problems solved by technology

[0002] Panels are widely used in all walks of life. At present, the insulation effect of the existing sound insulation panels is not ideal, or the insulation effect is acceptable but the sound insulation effect is not ideal.

It is impossible to take into account the two performances of heat preservation and sound insulation at the same time

[0003] At present, there are many building panels with thermal insulation and sound insulation used in wall construction. Most of these building panels are made of organic materials. People often feel The sound insulation effect is acceptable, but the thermal insulation performance is not good, or the thermal insulation performance is acceptable, but the sound insulation effect is not good. In short, the thermal conductivity and sound absorption rate are not ideal.

Moreover, thermal insulation and sound insulation panels made of organic materials, such as mineral wool sound-absorbing panels, will cause changes in the shape of the panels once they absorb moisture, and partially or completely lose their performance.

At the same time, due to the board with this performance, it is generally laid on the inner wall of the building wall during construction. However, in terms of the effect of thermal insulation, traditionally people generally believe that the effect of external thermal insulation is better than that of internal thermal insulation. Therefore, in In actual construction, on the one hand, in order to ensure the temperature inside the building, an insulation layer has to be added to the outer layer of the concrete wall. Compared with the insulation materials used in the insulation layer, the thermal insulation coefficient of concrete is extremely high, so the only way to add insulation layer If it is set very thick, the temperature inside the building can be guaranteed, and the construction cost will increase accordingly, which is not conducive to the stress of the structure and the safety of construction and use. On the other hand, in order to achieve the sound insulation effect, people lay sound insulation panels on the inner wall. increased construction costs
