the bottom sealing ink is formed by mixing 60-75% of modified acrylic resin, 10-20% of cellulose and 15-25% of terpineol in percentage by mass.
The UV gloss oil is a transparent coating, and is converted from a liquid state to a solid state by irradiation of an LED lamp after being rolled on the surface of a substrate. After the UV gloss oil is coated on the surface of the glass in a rolling mode, a polyurethane transparent film with drawn wires is covered, the LED lamp irradiates and solidifies the polyurethane transparent film to form a drawn wire coating, then the polyurethane transparent film is peeled off, the pattern lines on the polyurethane transparent film are transferred to the surface of the glass, and the solidified UV gloss oil is clear in lines, bright, attractive and mellow in texture. After the polyurethane transparent film is peeled off, high-brightness metallic paint is printed on the wire-drawing coating through silk screen printing, so that the metallic luster of the glass surface is increased, and the metallic texture is enhanced.
