Abstract

The invention belongs to the technical field of novel flame-retardant heat-insulation materials, and in particular, relates to a basalt fiber composite heat insulation board and a preparation method thereof; the basalt fiber composite heat insulation board is prepared from the following raw materials: polystyrene, basalt fibers, silica fume fibers, poly aluminum chloride, a cryolite powder, waterborne alkyd resin, a coconut shell powder, a fluorocarbon emulsion, sodium anthraquinone sulfonate, a nano hydroxyapatite powder, propylene glycol methyl ether acetate, and a modifier. Compared with the prior art, the basalt fiber composite heat insulation board has the following advantages: with cooperative use of the basalt fiber and the silica fume fiber, the prepared composite heat insulation board has excellent mechanical properties and processability, and can work stably for a long term in a condition of high temperature of 600 DEG C; through cooperative effect with other raw materials, the composite heat insulation board keeps relatively good physical properties in an environment having the temperature increased gradually, reduces costs, and has wider application range.

Description

technical field [0001] The invention belongs to the technical field of novel flame-retardant and heat-insulating materials, and in particular relates to a basalt fiber composite heat-insulating board and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the use of heat insulation boards in buildings is increasing. In the current market, glass fiber heat insulation boards occupy a large share. Due to the low temperature resistance of glass fibers and the cost of production High, pollute the environment; and carbon fiber is expensive, and imports are restricted; so a new type of alternative product is needed to meet market demand. Contents of the invention [0003] The object of the present invention is to provide a basalt fiber composite heat insulation board and a preparation method thereof in view of the existing problems. [0004] The present invention is achieved through the following technical solutions: a b...
