Problems solved by technology

However, the existing preparation process and mixing ratio obviously cannot meet the increasing requirements of the construction industry for energy saving and environmental protection as well as the performance of the material itself. The heat insulation and fire resistance performance is poor, and the strength is not high.
At present, the fiber-reinforced fireproof boards that are widely used in the market use relatively cheap plant fibers, which are mixed with glue or resin, gypsum, magnesium compounds and other inorganic substances or cement, and finally pressurized into a board shape. However, the above When the plant fiber board absorbs water for a long time, it will produce water seepage deformation and disintegrate its shape, and its fire resistance, weather resistance, corrosion resistance and output will be affected to a certain extent, which cannot meet the actual market demand, so it cannot be widely accepted by the market
[0003] It can be seen that the current fiber-reinforced fireproof insulation board still has many shortcomings, which cannot meet the growing market demand, and an excellent solution is urgently needed

Abstract

The invention discloses a fiber-reinforced fireproof insulation board. The fiber-reinforced fireproof insulation board is prepared from the raw materials in parts by weight: 80-100 parts of fly ash, 30-50 parts of expanded perlite, 10-20 parts of ceramsite, 10-20 parts of plant fiber, 5-10 parts of floating bead, 5-8 parts of meerschaum, 3-5 parts of sodium fluosilicate, 3-5 parts of calcium formate, 3-5 parts of flame retardant, 0.1-0.5 part of oleic triisopropanolamine and 0.1-0.3 part of glycol dimethyl ether. According to the fiber-reinforced fireproof insulation board, industrial production wastes are adopted as main raw materials, so that the production cost is reduced; through the organic combination and generated synergism of the fly ash, lightweight aggregate and additives, the defects in the existing building insulation boards can be effectively overcome.

Description

technical field [0001] The invention belongs to the technical field of building thermal insulation materials, and in particular relates to a fiber-reinforced fireproof thermal insulation board and a preparation process thereof. Background technique [0002] In the field of thermal insulation materials, fireproof insulation boards are a type of building materials developed in recent years. However, the existing preparation process and mix ratio obviously cannot meet the requirements of the building industry for energy saving, environmental protection and the performance of the material itself. The heat insulation and fire resistance performance is poor, and the strength is not high. At present, the fiber-reinforced fireproof boards that are widely used in the market use relatively cheap plant fibers, which are mixed with glue or resin, gypsum, magnesium compounds and other inorganic substances or cement, and finally pressurized into a board shape.
