Vitrification micro-sphere heat-preservation sound-insulation board and manufacturing method thereof

Abstract

The invention relates to a vitrified microsphere thermal insulation acoustical board, which has components as follows: vitrified microsphere, expanded perlite, cement, re-dispersible latex powder, water, methyl hydroxyethylcellulose ether, blended fiber, motor micropore plasticizer and water reducer. The preparation method includes the following steps: the components are evenly mixed; the mixed material is rolled by a roller press and is parched and cut after standing. Through inspection, thermal insulation performance of the vitrified microsphere thermal insulation acoustical board is much better than the prior organic product. Little cement consumption can directly cause reduction of thermal insulation coefficient; at the same time, dead weight is greatly lightened so that the formed sheet with lightened dead weight can improve the stress performance of building structure and is in favor of structural anti-seismic. Furthermore, as the vitrified microsphere and expanded perlite have fireproof, high and low temperature resistant and anti-aging performance, the fireproof performance and durability of the thermal insulation acoustical board can be improved. The vitrified microspherethermal insulation acoustical board can meet the need of structural element for strength and also greatly reduce energy consumption of the building to meet the need of building energy-saving standardof our country.

[0002] 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 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 only the insulation layer It is very thick to ensure the temperature inside the building, which increases the construction cost, 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. In this way, Undoubtedly increased construction costs
