Abstract

The invention discloses an extruded acryl composite foam board and a preparation method thereof. The extruded acryl composite foam board comprises polymethyl methacrylate, a titanium dioxide color master batch, a benzotriazole ultra-violet absorber and an acrylonitrile-polystyrene copolymer. The raw materials are dried firstly, and then the extruded acryl composite foam board is produced by special four-layer co-extrusion and secondary compound methods. The invention has the advantages that the thickness of the prepared acryl composite foam board can be controlled within the range of 0.8-10 mm; the acryl composite foam board is more widely applied; and in performance, acryl composite layers have better homogeneity and cohesiveness. Because an arabesquitic, colored and uvioresistant polymethylmethacrylate layer is adopted as a second layer, the color of a product can be kept stable throughout the year, and the product has the function of ultraviolet resistance.

After b, above-mentioned sheet material raw material are squeezed in the same distributor through extruding machine, are extruded into four rollers through a T shape die head and prolong in the pressure equipment, being extruded to shape forms the three-decker on wounded in the battle lamina surface;
C, on the flower-pattern layer surface also fully in the process of cooling; Through the 4th extruding machine; Body temperature is set in 200-250 ℃, measuring pump rotating speed 10-50r/min scope, UV, PMMA compound fusion plastification are clamp-oned the 2nd T shape die head after, be towed to four rollers and prolong pressure equipment; Promptly at the flower-pattern layer surface of three-layer co-extruded structure, the compound one deck PMMA of secondary layer.
Described four rollers prolong and comprise three mirror rollers and a patterned roll in the pressure equipment, wherein, are followed successively by little mirror roller, large mirror roller, large mirror roller, big-pattern roller according to arranging from the top down.
A described T shape die head is extruded corresponding position between second large mirror roller and patterned roll, and the 2nd T shape die head is extruded pairing position between first large mirror roller and second large mirror roller.
A described T shape die head and the 2nd T shape die head prolong the heteropleural relative direction of pressure equipment and extrude from four rollers.
Advantage of the present invention:
(1) can be controlled in 0.8-10mm on the extruded acryl composite foam board thickness through the present invention's preparation, suitable purposes is more extensive;
(2) this extruded acryl composite foam board can make sheet material acryl composite bed have uniformity and caking property preferably because of its unique four layers of co-extrusion and secondary complex technique;
(3) the present invention has adopted decorative pattern and pattern all inner at sheet material, makes sheet material in the process of using, have more aesthetic property and easy spatter property, and anti-ultraviolet function can make product all keep colour stable throughout the year, and outdoor use can nondiscolouring in 10 years;
(4) the present invention is unique four layers of co-extrusion and secondary complex technique have improved production efficiency of products than the production of traditional secondary casting method, the mechanization degree height.
