Second purpose of the present invention provides the preparation method of above-mentioned acryl composite foam board, comprises the steps:
A, at first above-mentioned raw materials is stirred in mixed-hopper separately respectively, simultaneously the drying of carrying out 1-7 hour in temperature is 60-90 ℃ scope is handled, an extruding machine body temperature is set in 200-250 ℃ of scope, with PMMA, the titanium dioxide color masterbatch, be expressed into distributor as the sheet material second layer behind the benzotriazole ultra-violet absorber fusion plastification, second extruding machine body temperature is set in 200-260 ℃ of scope, ABS, be expressed into behind PMMA and the benzotriazole ultra-violet absorber fusion plastification in the distributor as the 3rd layer of sheet material, the 3rd extruding machine body temperature is set in 200-250 ℃ of scope, with UV, be expressed into distributor behind the PMMA fusion plastification as the 4th layer of sheet material;
After b, above-mentioned sheet material raw material are squeezed in the same distributor by 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, by the 4th extruding machine, body temperature is set in 200-250 ℃, measuring pump rotating speed 10-50r/min scope, after UV, PMMA compound fusion plastification clamp-oned the 2nd T shape die head, be towed to four rollers and prolong pressure equipment, promptly on 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 by 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 the four layers of co-extrusion and the secondary complex technique of its uniqueness;
(3) the present invention has adopted decorative pattern and pattern all in sheet material inside, makes sheet material have more aesthetic property and property easy to clean in the process of using, and anti-ultraviolet function can make product all keep colour stable throughout the year, and outdoor use can nondiscolouring in 10 years;
(4) four of uniqueness of the present invention layers of co-extrusion and secondary complex technique, more traditional second casting method are produced and have been improved production efficiency of products, mechanization degree height.
Description of drawings
Fig. 1 is the arrangement mode and the T pattern head location drawing that four rollers prolong four rollers in the pressure equipment.
Wherein: 4 is the big-pattern roller; 1 is little mirror roller; 2 is the large mirror roller; 3 is the large mirror roller; A is a T shape die head; B is the 2nd T shape die head.
