Abstract

The invention provides a flame-retardant inorganic compound EPS (Expanded Polystyrene) insulation board and a preparation method thereof. The flame-retardant inorganic compound EPS insulation board is prepared from the following components in parts by weight: 15 to 25 parts of volatile polystyrene, 100 to 150 parts of inorganic gel material, 15 to 30 parts of inorganic filler, 5 to 20 parts of graphite, 2 to 8 parts of ammonium polyphosphate, 1 to 5 parts of zinc borate, 1 to 5 parts of cellulose ether, 0.1 to 1 part of organic silicon water repellent, 5 to 10 parts of gelatine powder, and 0.1 to 1 part of foaming agent. The flame-retardant inorganic compound EPS insulation board is subjected to inorganic composite modification, so that A2-grade fire resistance is reached, superior heat-preserving performance is realized, the heat conductivity coefficient is up to about 0.05W(m.K), and the water absorption is less than or equal to 10 percent; moreover, the flame-retardant inorganic compound EPS insulation board has the characteristics of easiness in preparation, low cost and the like. The flame-retardant inorganic compound EPS insulation board meets the requirement on flame retardance of outer-wall insulation boards in Code for Fire Protection Design of Buildings (GB50016-2015), and can be suitable for external thermal insulation projects of building outer walls, so that the flame-retardant inorganic compound EPS insulation board has a wide application prospect and a good market potential.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a flame-retardant inorganic composite EPS thermal insulation board, and also to a preparation method of the flame-retardant inorganic composite EPS thermal insulation board. Background technique [0002] Under the background of vigorously promoting building energy conservation in our country, all buildings must meet the corresponding energy-saving standards, but about 80% of the insulation materials currently used are organic combustible materials, and the external wall insulation system has poor fire performance. The thin plaster organic insulation system material is the main material. Judging from the current situation of fire protection technology for external thermal insulation systems of external walls and the frequency of fires, it is a major issue to improve the fire safety of external thermal insulation systems of various buildings. [0003] With the gradual improvement o...
