Light flame-retardant thermal-insulation energy-saving building material and preparation method thereof

Abstract

The invention discloses a light flame-retardant thermal-insulation energy-saving building material. The energy-saving building material is prepared from the following raw materials in parts by weight: 20-25 parts of 425# high-alumina cement, 3-5 parts of epoxy rubber powder, 10-16 parts of glass hollow bodies, 4-8 parts of calcined gypsum powder, 5-9 parts of an inorganic bonding agent, 15-25 parts of modified mineral substance powder, 7-9 parts of reinforced fibers, 2-5 parts of aluminum silicate powder, 10-20 parts of potassium methyl silicate and 8-12 parts of a flame retardant. The energy-saving building material has relatively good properties such as compressive strength, impact resistance and thermal insulation property and, is light, economic, high in strength, capable of insulating heat, energy saving and environment friendly, simple and convenient to construct, good in processability and applicable to water seepage prevention, sound insulation and efficient thermal insulation and energy saving of various building wall surfaces; and meanwhile, the raw materials of the energy-saving building material are safe, reliable, harmless to the environment and easily available, so that the energy-saving building material is relatively low in cost and has a simple process, relatively high practical values and good application prospects.

Description

technical field [0001] The invention relates to the technical field of energy-saving thermal insulation materials, in particular to a lightweight flame-retardant thermal insulation energy-saving building material and a preparation method thereof. Background technique [0002] The essence of building energy conservation is to scientifically and rationally improve the thermal performance of the outer envelope according to the characteristics of different climate zones. Building insulation is a measure to reduce the heat emitted from the building indoors to the outside, and plays an important role in creating a suitable indoor thermal environment and saving energy. At present, polystyrene foam board and polyurethane foam board are used as the main insulation materials in the world, and this method is also used as the main construction technology for wall insulation in my country. However, there are many disadvantages in the use of polystyrene foam boards and polyurethane foam ...

AI Technical Summary

Problems solved by technology

[0004] In addition, in the north of my country, in order to keep the building wall insulated and meet the national energy-saving target of 50%, a layer of 110mm thick benzene board, 80mm thick polyurethane foam board or extruded board is added to the wall structure, although it can To a certain degree of heat preservation effect, but there are various problems such as flammability, toxicity, short service life, complicated construction, easy slipping, poor bonding strength, etc.

At present, it is difficult to achieve the target of 65% energy saving. Even if it can be achieved, the construction is cumbersome and difficult, and the thickness above 110mm will bring great difficulties to the exterior decoration.
