Abstract

The invention discloses a composite resin film with good light screen printing effect and a preparation method thereof. The film comprises a light screen-printed layer, a core layer and a heat-sealing layer. The light screen-printed layer comprises the following raw materials: isotactic polypropylene, aliphatic polyimide, polyurethane, polyarylsulfone and polycaprolactam. The core layer comprises the following raw materials: isotactic polypropylene, polyphenyl ether, polyethylene naphthalate and an antistatic agent. The heat-sealing layer comprises the following raw materials: polycarbonate, amino resin, polyhydroxybutyrate-pentanoate, polyvinyl chloride and a slipping agent. According to the preparation method, a three-layer co-extrusion process is employed; production speed and screw speed are controlled; the light screen-printed layer is extruded from an auxiliary extruder 1 at a temperature of 225 DEG C; the core layer is extruded from a main extruder at a temperature of 250 DEG C; and the heat-sealing layer is extruded from an auxiliary extruder 2 at a temperature of 225 DEG C. The light screen-printed film prepared in the invention has improved polarity and anti-static property and presents better light screen printing effect in printing.

Description

technical field [0001] The invention relates to the field of layered products, in particular to a composite resin film with good shallow screen printing effect and a preparation method thereof. Background technique [0002] Shallow screen printing technology has outstanding advantages such as good formability, rich colors, and high combination precision, and is especially suitable for application in exquisite printed products with strict quality requirements and high control levels. Shallow screen printing technology overcomes the problems of fading and blurring of printed products produced by flat film printing technology, and promotes the quality of printed products to a higher level. Nevertheless, shallow screen printing technology often degrades the quality of printed products due to problems such as uneven coloring, board blocking, and dry board during actual operation. Therefore, it is necessary to optimize and improve the properties of the substrate film used in shal...
