Abstract

The invention relates to the production technology of a mirror surface black decoration film. The production technology comprises the following steps that 1, black master batches are prepared, EVA resin with the melt index being 0.5 g/10 min-5 g/10 min at the temperature of 190 DEG C is adopted as a master batch base material, an ultraviolet absorber, an antioxidant and superfine carbon black are added into the base material, macromolecule wax is adopted as a dispersing agent and extruded and formed on a double-screw extruder, and the specific area of the superfine carbon black is 2500 m<2>/g-3000 m<2>/g; 2, the black master batches, the EVA resin and a coupling agent are mixed uniformly, and the melt index of the EVA resin ranges from 5 g/10 min to 15 g/10 min at the temperature of 190 DEG C; 3, the mirror surface black decoration film is generated, and the extrusion temperature is controlled to range from 90 DEG C to 110 DEG C; and 4, embossing forming is carried out, rubber roller water temperature of embossing forming equipment is controlled to range from 8 DEG C to 12 DEG C, a rubber roller is made of an integral silica gel material, hardness is controlled to range from 60 A to 80 A, roughness of sand meshes of the rubber roller is 14-18 meshes, steel roller water temperature is controlled to range from 10 DEG C to 15 DEG C, and the pattern depth ranges from 0.06 mm to 0.15 mm.

Description

technical field [0001] The invention relates to a production process of mirror black decoration. Background technique [0002] In the field of architectural decoration, laminated glass has been more and more widely used due to its excellent characteristics such as beauty and firmness. Laminated glass includes a glass film layer in the center and glass on both sides. The existing glass film is generally monochromatic, and the laminated glass produced is generally transparent and monochromatic. When it is necessary to show the combined color effect, laminated glass of multiple colors is generally used in combination. However, with the improvement and transformation of people's aesthetic ability, monochrome laminated glass can no longer meet people's aesthetic needs, and people are in urgent need of film products with mirror black effect. The above-mentioned production process does not exist in the prior art. There are many defects in the existing black decorative EVA film: (1...
