Abstract
The utility model relates to a kind of building exterior wall heat preserving polyurethane thermal insulation board, comprise polyurethane foam, the first flame retardant coating is provided with above polyurethane foam, the second flame retardant coating is provided with below polyurethane foam, be provided with the first glass fibre cement cloth above first flame retardant coating, below the second flame retardant coating, be provided with the second glass fibre cement cloth.The utility model structure is simple, design ingenious, after polyurethane thermal insulation board adds flame retardant coating between glass fibre cement cloth and polyurethane foam, increase the adhesive property between glass fibre cement cloth and polyurethane foam, adhesion strength brings up to 150KPa by 100KPa, improves the fire resistance of polyurethane thermal insulation board.
Description
Technical field
The utility model relates to a kind of building exterior wall heat preserving polyurethane thermal insulation board, belongs to heat insulation plate for building material technical field.
Background technology
Along with the requirement of country to building energy conservation is more and more higher, polyurethane thermal insulation board, because the heat-insulating property of its excellence uses more and more extensive as external-wall heat-insulation material, particularly takes into account heat-insulating property with the warming plate of glass fibre cement cloth and the integrated sandwich structure of polyurethane because of it and fire resistance is widely used.But in actual use, glass fibre cement cloth bad situation bonding with between polyurethane foam can be encountered, the risk come off after existing installation, also affect its overall flame performance.
Summary of the invention
The purpose of this utility model is the problem in order to solve existing polyurethane thermal insulation board fire resistance poor effect, provides the simple building exterior wall heat preserving polyurethane thermal insulation board of a kind of structure.
The utility model adopts following technical scheme: a kind of building exterior wall heat preserving polyurethane thermal insulation board, comprise polyurethane foam, the first flame retardant coating is provided with above described polyurethane foam, the second flame retardant coating is provided with below described polyurethane foam, be provided with the first glass fibre cement cloth above described first flame retardant coating, below described second flame retardant coating, be provided with the second glass fibre cement cloth.
Further, the thickness of described first flame retardant coating and the second flame retardant coating is 0.4 ~ 0.6mm.
Further, described first flame retardant coating and the second flame retardant coating adopt melamine class amino resins to be base-material, and TCPP and expanded graphite are that fire retardant is made.
The utility model structure is simple, design ingenious, after polyurethane thermal insulation board adds flame retardant coating between glass fibre cement cloth and polyurethane foam, increase the adhesive property between glass fibre cement cloth and polyurethane foam, adhesion strength brings up to 150KPa by 100KPa, improves the fire resistance of polyurethane thermal insulation board.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral: polyurethane foam 1, first flame retardant coating 2, second flame retardant coating 3, first glass fibre cement cloth 4, second glass fibre cement cloth 5.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, a kind of building exterior wall heat preserving polyurethane thermal insulation board, comprise polyurethane foam 1, the first flame retardant coating 2 is provided with above polyurethane foam 1, the second flame retardant coating 3 is provided with below polyurethane foam 1, the thickness of the first flame retardant coating 2 and the second flame retardant coating 3 is 0.4 ~ 0.6mm, the first glass fibre cement cloth 4 is provided with above first flame retardant coating 2, the second glass fibre cement cloth 5 is provided with below second flame retardant coating 3, first flame retardant coating 2 and the second flame retardant coating 3 adopt melamine class amino resins to be base-material, TCPP and expanded graphite are that fire retardant is made.
Preparation method: first uniform application anti-flaming dope forms the first flame retardant coating 2 below upper strata first glass fibre cement cloth 4, then on the second glass fibre cement cloth 5, uniform application coating forms the second flame retardant coating 3, then utilize the self bonding function of polyurethane foam material to couple together the first glass fibre cement cloth and the second glass fibre cement cloth of smearing flame retardant coating, form the polyurethane thermal insulation board of sandwich construction.
