The production method includes: firstly producing the high-density high-hardness weather resistance self breadcrust polyurethane foam plastic plate, and then using adhesive or directly foaming for compounding the a low density polyurethane foam plastic plate on the high-density high-hardness weather resistance self breadcrust polyurethane foam plastic plate. The invention has light weight of the product, and simple technology; is safe and reliable; and can achieve industrial production and assembly construction.
Description
Technical field:
The present invention relates to a kind of constructional materials, is polyurethane thermal insulation board and production technology.
Background technology:
The method site operation that polyurethane heat-insulation technology in the past adopts spraying usually utilizes the polyurethane high adhesive property, is bonded in the surface of wall of insulation, to reach the effect of energy-saving heat preserving.Polyurethane is the good binding material of a kind of adhesive property, can carry out good bonding with a lot of object surfaces.But the resulting insulation layer of the method for such site operation is because not protection of surface suffers hard thing collision back cracky, thereby lost heat preservation effect.And site operation is difficult to guarantee construction quality for vertical wall construction difficulty.Simultaneously, site operation gained insulation layer surface is not attractive in appearance.
In addition, because the uvioresistant of conventional polyurethanes foamed material and weather resistance are undesirable, so can not directly expose in outdoor environment.So the practical value of common pure polyurethane foam insulation plate is undesirable.
Therefore, another is the polyurethane heat-insulation decorative board material that batch production is produced, and in order to adapt to the needs in market, reaches the requirement of attractive in appearance and weather resistance, this class polyurethane heat-insulation decorative board material usually will be at its surface adhesion or applying ceramic tile or cement board when producing, perhaps aluminium alloys etc.But this technique for manufacturing decorative boards or post-processed complex process.For example a kind of decorative panel is chosen in its external surface decoration ceramic tile, and its complex manufacturing is wanted present polyurethane sheet surface applied polymer mortar, and then added alkali-resistant glass fibre cloth, and then adds the one layer of polymeric mortar, and last surface could the applying ceramic tile.The applying of ceramic tile and polyurethane realizes by adhesive like this, though solved the weatherability problem of polyurethane thermal insulation board, because the about 10mm of the thickness of ceramic tile itself, its weight is heavier, 1 square metre about about 20 kilograms, therefore cause easily to come off.In the future safety is impacted.While production and construction complexity.
Summary of the invention:
The object of the present invention is to provide a kind of in light weight, safe and reliable, technology is simple, can realize suitability for industrialized production, construction assemblingization weather resistant polyurethane insulation composite slab and production method.
