Abstract
The utility model improves the polyurethane composite insulated board, in particular to a polyurethane composite board of high intensity of flex, bending and compression resistance, which is characterized in a neutralized polyurethane foaming layer or a reticular reinforcement layer on the surface. Due to the provided reticular reinforcement layer, the utility model not only highly improves the structural intensity of the polyurethane foaming plate, but also increases the anti-flex intensity by more than 5 times and the compression resistant intensity by more than 3 times through testing, which greatly extends the use of the polyurethane foaming plate, such as the vent tube of an air-conditioner, other decoration and furnishing materials, and light wall materials, etc. The reticular reinforcement layer is adopted to help the permeating and cross linkage of the polyurethane, which is uneasy to be stratified with homogeneous, high and good integral intensity.
Description
Technical field
Utility model is the improvement to polyurethane composite insulating board, relates in particular to a kind of anti-folding, bending resistance, Rigid foam polyurethane material that compressive strength is high.
Background technology
Chinese patent 97230945,98228503 disclosed two surface layers are aluminium foil, and the centre is the composite insulating board of hard polyurethane foam layer, as the air-conditioning system airduct.This heat preservation plate material of mainly forming by the polyurethane foam layer, intensity and hardness are relatively low, and the scope of application is narrow, can only make air conditioning wind pipe and use.Chinese patent 01254296 disclosed foam heat-insulating board, employing strengthens the magnesium oxychloride cement plate at polystyrene foam warming plate or polyurethane foam insulation plate two sides composite glass fiber, though improved timber intensity, but the bigger panel weight that increased is used for building, has increased load, in addition because the surface layer plate is a cement board, in use easily produce dust pollution, the surface layer plate is coarse, can not be used as decorative sheet.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of structural strength big, the polyurethane foam composite plate that hardness is high.
Another purpose of utility model is to provide a kind of surface layer attractive in appearance, the polyurethane foam composite plate that structural strength is big.
The utility model purpose realizes that main the improvement is that netted enhancement Layer is set in the polyurethane foam layer, thereby improves foaming slab integral structural strength.Specifically, utility model polyurethane foam composite plate is characterized in that in the said polyurethane foam layer and/or surface layer has netted enhancement Layer.
The said netted enhancement Layer of utility model can be a staggered net such as plastic deeping, wire lath sheet, glass fiber mesh sheet, nylon wire, papery net.It can be arranged in the polyurethane foam layer, also can be arranged on the foaming surface layer.Be excellent in the foaming layer to be arranged on especially wherein, in the polyurethane foam process, can form integral body, and can not cause delamination to have permanent structural strength.According to the intensity needs, lamina reticularis can be one deck, also can be multilayer.
Utility model second purpose realizes that can be compounded with flexible cladding again at the polyurethane foam laminar surface, said flexible cladding can be thin layer flexible materials such as aluminium foil, cloth, facing paper, plastic sheeting.
Utility model is because at the netted enhancement Layer of the middle and/or surperficial increase of polyurethane foam layer, not only improved the structural strength of polyurethane foam board greatly, rupture strength can improve more than 5 times after tested, compressive strength can improve more than 3 times, widened the scope of application of polyurethane foam board greatly, can make ventilation duct of air conditioner, also can do other and decorate decoration, furniture material, light wall material etc.; And adopt the grid enhancement layer, and help the osmotic crosslink of the polyurethane on grid two sides, be difficult for layering, intensity is even, intensity height, good integral strength.
Below in conjunction with three specific embodiment, further specify the utility model structure, but embodiment not the qualification to the utility model concrete structure.
Description of drawings
Fig. 1 is the utility model first example structure schematic diagram.
Fig. 2 is the utility model second example structure schematic diagram.
The specific embodiment
Embodiment 1: referring to Fig. 1, utility model Rigid foam polyurethane 1 has one (or two) layer glass fiber mesh 2 in foaming layer.
Embodiment 2: referring to Fig. 2, as described above, on the polyurethane foam board two sides, be compounded with aluminium foil finish coat 3 respectively.
Embodiment 3: as described above, two surface materials can also be other flexible finish materials.
Embodiment 4: as embodiment 1, netted enhancement Layer can also be arranged on surface layer.
Claims (4)
1, a kind of polyurethane foam composite plate is characterized in that in the said polyurethane foam layer and/or surface layer has netted enhancement Layer.
2,1 described polyurethane foam composite plate as requested is characterized in that said netted enhancement Layer is located in the middle of the foaming plate.
3,1 or 2 described polyurethane foam composite plates as requested is characterized in that said polyurethane foam surface layer has flexible finish coat.
4,3 described polyurethane foam composite insulation boards as requested is characterized in that said flexible finish coat is decorations paper or aluminium foil.
