Abstract
The utility model relates to a polycarbonate sheet, i.e. a solid sheet. The polycarbonate sheet is characterized in that the polycarbonate sheet comprises a main body, and an UV absorbent protection layer formed on the surface of the main body by the co-extrusion method; and the UV absorbent protection layer has a thickness of 30-50 micrometers. The polycarbonate sheet manufactured by the co-extrusion method is prevented from being damaged, being layered and falling off, and can sufficiently exert the effect of the absorbent and reduce the cost.
Description
Technical field
The utility model relates to a kind of sunlight force-bearing plate, promptly a kind of sunlight board force-bearing plate (solid slab).
Background technology
The sunlight board formal name used at school is a polycarbonate plate.All there is the problem that is subjected to the ultraviolet light irradiation and quick aging takes place in plastic plate, and each manufacturing enterprise all adopts diverse ways to address this problem, in the hope of prolonging the service life of product.The most practical and effective method is to add ultra-violet absorber in product, but the difference of adding technology can cause the world of difference of practical effect again.
Everybody adopts the surface-coated method at first; promptly be coated with the last layer ultra-violet absorber on the surface of sheet material; but because the compatibility of PC and other materials is very poor; so the back rainwater is installed to be dashed the coating on surface fall with regard to being easy to; consider product contingent damage in storage and transport process in addition; during production just the two sides at product be covered with diaphragm; this diaphragm must be torn after end is installed; and because the diaphragm toughness; so can glue the ultra-violet absorber of a large amount of surface-coated in the process of tearing, so actual effect is very poor.
Now a lot of producers adopt mixes additive process, promptly in the PC major ingredient, sneak into a certain amount of ultra-violet absorber (about 5%), extrude through high-temperature fusion together, this has solved the layering problem that comes off, but because the very most of of plate surface still exposes under sunshine, therefore the aging of plate surface still taken place inevitably, because ultraviolet radiation absorption dosage costs an arm and a leg, adds the rising significantly that a high proportion of absorbent like this has also caused product cost in addition.
The utility model content
Order of the present utility model is to propose a kind of new sunlight force-bearing plate, to solve the problem that the ultra-violet absorber layer is impaired easily, layering comes off that present Merlon solid slab exists.
A kind of sunlight force-bearing plate is characterized in that, comprising: the sunlight force-bearing plate body, by one deck ultra-violet absorber protective layer of coetrusion in described sunlight force-bearing plate body surface formation; 30 microns～50 microns of described ultra-violet absorber protection bed thickness.
That sunlight force-bearing plate described in the utility model is not easy is impaired, layering comes off, and has given full play to the effect of absorbent, and has reduced cost.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of a kind of embodiment of sunlight force-bearing plate described in the utility model.
