Abstract
The invention discloses an exterior wall insulation board and relates to the field of building engineering materials. The exterior wall insulation board is made from, by weight, 40 to 60 parts of polystyrene, 20 to 30 parts of boron fiber, 12 to 18 parts of magnesium hydroxide, 2 to 4 parts of antimonous oxide, 1 to 3 parts of white carbon black, 1 to 2 parts of defoamer, and 0.8 to 1.2 parts of lubricant. By the use of the exterior wall insulation board, the problem that the existing extruded exterior wall insulation board is poor in flame retardance is solved.
Description
Technical field
The present invention relates to architecture engineering material technical field, especially a kind of thermal insulation plate for external wall.
Background technology
Thermal insulation thermal insulation board is the common materials in building trade, is used for the roofing of buildings, the heat insulating of body of wall, to reduce indoor heat loss, realizes environmental protection and energy saving.The mixed slurry of traditional thermal insulation plate for external wall mainly cement and heat-insulating granules material, is poured in metope and forms thermal insulation layer, this warming plate quality weight, after duration of service is long, easily comes off from metope.Existing thermal insulation plate for external wall is toward lighting future development, a kind of lightweight thermal insulation plate for external wall that extrusion moulding type thermal insulation thermal insulation board is common, this thermal baffle has light weight, intensity is high, resistance to compression good, thermal conductivity is low, the advantage such as good, corrosion-resistant, anti-aging, the easy carrying of moisture resistance and cutting, but the flame retardant properties of existing extrusion moulding type thermal insulation plate for external wall is poor.
Summary of the invention
The object of this invention is to provide a kind of thermal insulation plate for external wall, it can solve the poor problem of existing extrusion moulding type external wall insulation flame retardant properties.
In order to solve the problem, the technical solution used in the present invention is: a kind of thermal insulation plate for external wall is made up of the raw material of following parts by weight: polystyrene 40-60 part, boron fibre 20-30 part, magnesium hydroxide 12-18 part, antimonous oxide 2-4 part, white carbon black 1-3 part, defoamer 1-2 part, lubricant 0.8-1.2 part.
In the technical scheme of above-mentioned thermal insulation plate for external wall, technical scheme can also be more specifically: polystyrene 48 parts, boron fibre 25 parts, magnesium hydroxide 16 parts, antimonous oxide 3 parts, white carbon black 2 parts, defoamer 1.5 parts, lubricant 1 part.
Further, described polystyrene is foaminess drama ethene particle.
Further, boron fibre is nanometer boron fibre.
Further, the fineness of white carbon black is more than 1300 orders.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: this thermal baffle has high temperature resistant, withstand voltage, bending resistance, resistance to shrinkability, the feature of acid and alkali-resistance, organic solvent, and its thermal conductivity is low, burning grade reaches more than B level.
