High-scintillation pearlized film produced by tape casting method and preparation method of high-scintillation pearlized film

Abstract

The invention discloses a high-scintillation pearlized film produced by a tape casting method and a preparation method thereof, and belongs to the field of decorative materials. Comprising a three-layer structure formed by co-extruding a surface layer, a middle layer and a bottom layer, the surface layer comprises PMMA (polymethyl methacrylate) resin, the middle layer comprises polyvinyl chloride resin and mica pearlescent pigment, and the bottom layer comprises polyvinyl chloride resin and MBS (methyl methacrylate-butadiene-styrene) resin; the particle size of the mica pearlescent pigment is 10-300 [mu] m. The high-flicker pearlized film produced by the tape casting method is formed by co-extrusion of three layers of different materials, has good cohesiveness and high stability, and has the effects of high gloss and high flicker; the problem of direct adhesive force fastness between the high-flicker pearlized film and a plate and a metal piece can be solved; the co-extruded high-flicker pearlized film is free of VOC (volatile organic compounds), environment-friendly and nontoxic. According to the preparation method, three layers of different materials are extruded through three-layer co-extrusion casting equipment, the cohesiveness and stability between different layers are improved, production procedures are reduced, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the field of decorative materials, and in particular relates to a high-scintillation pearlescent film produced by a casting method and a preparation method thereof. Background technique [0002] Pearlescent film has the functions of packaging, decoration and protection. Because of its certain pearlescent effect, gorgeous color and good decorative performance, it will be prepared by different production methods for different scenes. It is used for furniture decoration materials. Currently, the following are used Two production methods are prepared: (1) spraying method; this production method is a three-stage process method, namely spraying primer first, then spraying pearlescent paint layer, and finally spraying transparent topcoat protective layer. (2) Coating method: first produce a transparent mask and a solid-color base film, then coat the base film (or mask) with a pearlescent glue layer, and finally the pearlescent glue la...

AI Technical Summary

Problems solved by technology

[0003] The production method of spraying has the following problems: the paint contains a large amount of organic solvents, which pollutes the environment and causes great harm to the employees; moreover, the production cost is high and the production efficiency is low;

[0004] However, the production method using the coating method has the following problems: long production process, high difficulty in product quality control, long production cycle, high production cost, heavy product odor, and VOC, which is harmful to human health
