A kind of insulation sandwich board
Technical field
The utility model relates to a kind of heat-insulation and heat-preservation sheet material, especially relates to a kind of insulation sandwich board.
Background technology
Along with the continuous development of society, the pattern, structure that are used for the heat preservation plate material of building decoration purposes are all in continuous variation, and at present, the insulation sandwich board of selling on the market has foam glass board; Calcium silicate board with microporous, rock cotton board etc., its weak point is, foam glass board; Calcium silicate board with microporous, rock cotton board density is bigger, causes weight big, and cost is high; Coefficient of thermal conductivity is big, does not reach the purpose of heat-insulation and heat-preservation efficiently, and energy-saving effect is not satisfactory.
The utility model content
The purpose of the utility model is exactly to provide a kind of in light weight, the insulation sandwich board that heat preservation and insulation is good for the defective that overcomes above-mentioned prior art existence.
The purpose of the utility model can realize through following technical scheme: insulation sandwich board; Comprise surface layer and laminboard layer; Described surface layer is the non-woven fabric compounded plate that glass strengthens thermoplastic resin sheet material and nonwoven composition; Described laminboard layer is a polyurethane foam board, and surface layer is provided with two-layer, is bonded in the two sides up and down of laminboard layer respectively through adhesive.
As preferably, described surface layer is that glass fiber strengthens thermoplastic resin sheet material and the hot-forming non-woven fabric compounded plate of nonwoven.
As preferably, described laminboard layer is for adding the polyurethane foam board of fire retardant, thereby makes sandwiched plate have fire-proof function.
As preferably, described adhesive is any in polyurethane, combined polyether or the isocyanates.
As preferably, the described laminboard layer thickness of the surface layer of two sides up and down equates.The polyurethane foam board thickness of the surface layer of two sides up and down equates.
As preferably, the thickness of described surface layer is 2~10mm, and the thickness of described laminboard layer is 30~120mm.
As preferably, the thickness of described surface layer is 5mm, and the thickness of described laminboard layer is 75mm.
Surface layer and laminboard layer are designed to above-mentioned thickness, are to take into account to have considered insulation, intensity and financial cost, if the thickness of surface layer and laminboard layer increases, insulation, stability can not significantly improve, but the insulation stability can not get guaranteeing; Draw through test of many times, surface layer and laminboard layer are designed to above-mentioned thickness, not only make it have excellent insulating, stability, and have remarkable economical property.
Obvious superiority such as compared with prior art, the utility model heat insulation effect is very good, is applicable to-30~70 degrees centigrade, has sound-insulating and heat-insulating, and is moistureproof corrosion-resistant, fire-retardant; And weight alleviates greatly; And take into account and considered insulation, intensity and financial cost, surface layer and laminboard layer are designed to suitable thickness, not only make it have excellent insulating, stability, and have remarkable economical property.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1 is that surface layer, 11 is that nonwoven, 2 is laminboard layer for glass strengthens thermoplastic resin sheet material, 12.
