A kind of fire-retardant wall insulated board
Technical field
The utility model relates to a kind of warming plate, and specifically a kind of fire-retardant wall insulated board, belongs to warming plate field.
Background technology
At present, when using polyurethane material, often adopt the method for in-situ spraying, on the body of wall that needs to be out of doors incubated, spray polyurethane material liquid, after foaming, form heat insulation protecting layer.But: the impact that in-situ spraying method is subject to weather is larger, in rainy day or snow day, is unsuitable for adopting in this way; And when polyurethane material liquid is sprayed on body of wall, due to the effect of gravity, liquid can glide, heat insulation protecting layer unevenness that final foaming is formed; In addition, polyurethane material liquid is in the process of foaming, and some organic solvents can evaporate, thus contaminated environment.Afterwards, people generally adopted at factory building polyurethane were processed into individual layer sheet material, were then affixed on and on metope, formed heat insulation protecting layer.Name is called " a kind of novel flame-retardant foamed material wall insulated board " application number provides a kind of wall insulated board for the Chinese utility model patent of " CN201120555808.8 ", comprise two layers of foam cement flaggy, between two layers of foam cement flaggy, be provided with a layer of polyurethane, on the surface of foamed cement flaggy, scribble anticracking grout and alkaline-resisting grid layer of cloth, together with described foamed cement flaggy is closely poured in polyurethane layer.Although heat insulation effect, sound insulation value and fireproof performance have obtained certain lifting,, intensity is lower, and bonding is fixing and insecure, easily occurs fracture disrepair phenomenon, has affected product quality, and application life is lower.
Utility model content
In order to address the above problem, the utility model has designed a kind of fire-retardant wall insulated board, and heat insulation effect, sound insulation value and fireproof performance further promote, and intensity is high, and bonding fixation, is not prone to fracture disrepair phenomenon, and product quality is high, long service life.
The technical solution of the utility model is:
A kind of fire-retardant wall insulated board, comprise upper and lower two layers of foam cement flaggy, between described upper and lower two layers of foam cement flaggy, be provided with one deck layer of polyurethane, together with described foamed cement flaggy is closely poured in layer of polyurethane, described layer of polyurethane inside is provided with metal sheet, improved the intensity of product, on described metal sheet, be evenly equipped with some through holes, connect described layer of polyurethane, thereby it is more firm that layer of polyurethane is combined with metal sheet, described foamed cement flaggy inside is provided with corrugated grid layer of cloth, grid layer of cloth is corrugated when having improved intensity, also make it have certain toughness, be not prone to fracture disrepair phenomenon, described grid cloth is glass fabric.
Further, in described polyurethane insulation coating, be evenly distributed with chopped glass fiber, the surface density of described chopped glass fiber is 150g/m
2, the length of described chopped glass fiber is 5cm, diameter is 10 μ m, by described polyurethane insulation coating inside, chopped glass fiber being set, when realizing heat-insulating property, can reach the increase of vertical and horizontal hot strength and modulus, improves the quality of products.
Further, on described upper foam cement flaggy, be also provided with calcium silicates layer, between described upper foam cement flaggy and calcium silicates layer, be also provided with melamine layer, further improved erasure effect.
Further, described foamed cement flaggy density is 100kg/m
3, described layer of polyurethane density is 60kg/m
3.
Further, the surface of described metal sheet scribbles anticorrosive coat, improves antiseptic property.
Further, described metal sheet is positioned at body of wall one side and is also provided with fixing suspension member, and described fixing suspension member is Z-shaped structure, has improved the adhesion firmness of product and body of wall.
The utility model has the advantage of: heat insulation effect, sound insulation value and fireproof performance further promote, and intensity is high, bonding fixation, is not prone to fracture disrepair phenomenon, and product quality is high, long service life.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
