Description
Technical field
The utility model relates to the prefabricated Rigid foam polyurethane of a kind of wall thermal insulating.
Background technology
Present general wall thermal insulation technology; mainly make heat insulating material with polystyrol plastic foam plate; adopt after loading to be fixed in surface of wall with the mode of pasting, anchoring combines; the polymer mortar that strengthens with the alkali-resistant glass fibre grid cloth is a topping again; outside implementing, decorates the topping lateral surface again; there is following shortcoming in this heat preservation technology: first polystyrol plastic foam plate is a kind of non-polar polymeric material; and adopt organic adhesion agent between the body of wall of traditional inorganic material, sticking to put (adhesive surface＞30%) fits with body of wall.Like this, adhesive surface is little, and bond strength does not reach requirement, and and body of wall between easily form cavity, easily cause the high-altitude pull out force and destroy, so must be aided with mechanical fixation; It two is generally should not surpass 4～5mm with the thickness of mortar coverage that grid cloth is strengthened, and the screed thickness of grid cloth both sides is answered basically identical, but on-the-spot artificial wet construction is difficult to guarantee that whole bodies of wall all meet the requirements, and therefore, the metope cracking is difficult to avoid; It is three because operation is various, and therefore long construction period, and based on on-the-spot manual work is difficult to the Control Engineering quality.
Summary of the invention
The purpose of this utility model is, provides a kind of wall thermal insulating prefabricated Rigid foam polyurethane, and this composite plate integrates thermal insulation, waterproof and decorates outward, easy construction, and quality and safety improve.
Realize the technical scheme of the utility model purpose: the prefabricated Rigid foam polyurethane of a kind of wall thermal insulating, once being bondd by exterior trim surface layer, polyurethane rigid foam plastic insulation layer, wire lath enhancement Layer and waterproof setting course successively to bottom from the top layer constitutes; Described waterproof setting course is to strengthen the sheet material that top layer hot pressing constitutes by the continuous yarn non-woven fabrics tackify of resin film waterproof sandwich layer and two sides of waterproof sandwich layer.
Above-mentioned prefabricated Rigid foam polyurethane, described exterior trim surface layer are any in microporous polyurethane facing concrete board, aluminium sheet or aluminium alloy plate, color steel, plastic plate, natural or artificial stone's plate, facing tile, coating ornamental surface plate, the color sand finish plate.
Above-mentioned prefabricated Rigid foam polyurethane is that the microporous polyurethane layer of concrete in the one side constitutes by waterproof setting course and hot press molding as the microporous polyurethane facing concrete board of exterior trim surface layer.
Above-mentioned prefabricated Rigid foam polyurethane is to be made of waterproof setting course and the dope layer that is coated in the one side as the coating ornamental surface plate of exterior trim surface layer.
Above-mentioned prefabricated Rigid foam polyurethane is to be made of waterproof setting course and the color layer of sand that is coated in the one side as the color sand finish plate of exterior trim surface layer.
The beneficial effects of the utility model: the wall thermal insulating of technical solutions of the utility model is the precast composite slab that disposable bonding constitutes with prefabricated Rigid foam polyurethane, the function that has decoration, thermal insulation, enhancing and waterproof combination simultaneously, once mount and to make body of wall have above-mentioned multiple function, thereby overcome the shortcoming of implementing wall thermal insulating technological operation complexity at present usually with on-the-spot paving successively; Because prefabricated profiled composite plate can guarantee that each layer of sheet material quality meets design standard, reduced the unsettled shortcoming of the construction quality that manually-operated brought; Because the insulation layer of composite plate of the present utility model is a polyurethane rigid foam plastic, therefore, when polyurethane foam forms insulation layer, have mobile and close-burning foam, the precast composite slab that each layer of constituting composite plate once is bonded to one, adhesive fastness is good between each layer, has overcome manually paving successively, each interlayer easily forms cavity, thereby causes the shortcoming of the easily separated and poor stability of interlayer; Because being positioned at the waterproof setting course of the utility model composite plate bottom is as the waterproof sandwich layer with resin film, its two sides are as strengthening the sheet material that the hot pressing of tackify top layer constitutes with continuous yarn non-woven fabrics, waterproof setting course rough surface and roughness are even, friction factor is big, cement and polyurethane material all there is good caking property, therefore, bonding between waterproof setting course and the polyurethane rigid foam plastic insulation layer is good, when composite plate of the present utility model and body of wall were pasted, only need fit with common plain cement (but also admixture is built glue in right amount) full sticking (adhesive surface 〉=90%) got final product.Omitted the method for attaching that interface processing must be arranged at present and use special-purpose adhesive, construction is simple, and construction costs is lower.
