Technical Field

The invention relates to a preparation method of foam glass, in particular to a preparation method of foam glass integrating color sound absorption and decoration.

Background

Building energy conservation is an extremely important policy of the country, and is a system engineering which benefits the nation and the people and benefits descendants. The functions of strengthening the heat preservation and heat insulation of buildings on improving the working and living environmental conditions of people and saving energy are direct and practical, in the heat preservation and heat insulation engineering of buildings in China, the high water absorption rate and the poor durability of heat preservation materials are two major problems, the heat preservation performance of the materials is greatly reduced, the heat preservation and heat insulation effect is influenced, and the energy consumption of an air conditioning system is increased. And after absorbing water, the heat-insulating layer becomes a water storage layer, so that the waterproof layer is bulged and damaged, leakage is caused, and water leakage still occurs for a long time after rain. In the structure of the external wall, because of the requirement of heat preservation and heat insulation, the wall body needs to be thickened to meet the requirement of use function, because no heat preservation material can replace the original red brick as the wall body material at present, and only the external heat preservation material can be adopted for heat preservation and heat insulation, the material which has light weight, good heat preservation performance, aging resistance, no water absorption and easy bonding is needed, and the foam glass is the most ideal heat preservation material. The foam glass is an excellent heat-insulating material for roofing or external wall.

The foam glass is prepared by adding auxiliary raw materials such as a foaming agent, a modifier, an accelerant and the like into cullet, and performing processes such as fine grinding, uniform mixing, roasting, foaming and the like. The foam glass has a large amount of uniform bubbles with the diameter of 1-2 mm inside, and the density of the bubbles is only 150-300 kg/m³1/7-1/15 of common glass. The structural and material properties of foam glass determine its many advantageous properties such as: light weight, heat insulation, sound absorption, chemical corrosion resistance, no oxidation, no combustion, no aging and the like, and is an excellent heat-insulating material. The foam glass is used for wall heat preservation and insulation, replaces red bricks, reduces the thickness of the wall, saves energy, indirectly enlarges the using area of a building and reduces the self weight of the building. When in construction, the common cement mortar or the polymer cement mortar is used for pasting, and the pasting force is strong. If the coating is used as an external wall coating surface layer, a layer of cement mortar is only needed to be smeared outside the foam glass layer for leveling.

With the development of society, the improvement of the quality of life of people and the enhancement of environmental awareness, the demand of people on the aspect of reducing environmental noise in work, study and life is higher and higher, the application of sound absorption materials is wider, and the use amount is increased year by year.
