Abstract

An inorganic fireproof lightweight aggregate expanded perlite heat-preservation board is composed of the following raw materials in parts by weight: 32-39 parts of expanded perlite, 1.1-1.6 parts of rock wool, 15-17 parts of a flame retardant, 2.6-4.6 parts of an alkali stain removing agent, 0.3-0.7 part of a preservative, 45-48 parts of water glass, 11-13 parts of a film-forming auxiliary agent, 13-17 parts of a lightweight aggregate, 16-19 parts of distilled water, and 5-7 parts of a re-dispersible emulsion powder. Because the rock wool is formed by adopting high-quality basalt, dolomite and the like as main raw materials, carrying out high temperature melting at the temperature of 1450 DEG C or more and then carrying out high speed centrifugation to obtain fibers, with addition of the rock wool in the expanded perlite, the fibers can effectively make the near expanded perlite connected together, therefore, the strength of the expanded perlite heat-preservation board after forming is effectively improved, and the expanded perlite heat-preservation board is not easy to crack. At the same time, the heat insulation and preservation ability and the waterproof ability of the expanded perlite heat-preservation board also can be improved, the frost resistance also is greatly enhanced, and the expanded perlite heat-preservation board is allowed to be not prone to frost cracking.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an inorganic fireproof light aggregate expanded perlite insulation board and a preparation method thereof. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's living standards, energy consumption is also increasing. In my country's total energy consumption, building energy consumption is one of the main aspects of my country's energy consumption. According to relevant reports, most of the newly added housing construction area in my country is high-energy-consuming buildings, and nearly 90% of existing buildings are high-energy-consuming buildings. The annual power consumption of buildings in the country accounts for more than 20% of my country's power generation, and the power consumption per unit building area is several times that of developed countries. The main reason is that my country's building insul...
