Abstract

The invention relates to a pearlescent PVC (Polyvinyl Chloride) thin film. The pearlescent PVC thin film is prepared from the following components in parts by mass: 60 to 80 parts of 5 type PVC, 10 to30 parts of 7 type PVC, 8 to 10 parts of fiber powder, 2 to 3 parts of ESO, 3 to 5 parts of calcium carbonate, 1.5 to 2.5 parts of BS-105, 0.5 to 1 part of 1203, 0.1 to 0.2 part of 8775, 0.005 to 0.01 part of 2147, 0.2 to 0.4 part of 736A, 1 to 2 parts of titanate, 1 to 2 parts of ACR-401 and 1 to 3 parts of CPE. According to the preparation method of the pearlescent PVC thin film disclosed by the invention, by adding the fiber powder, the pearlescent PVC thin film has the advantages of environment friendliness, health, low cost and capability of effectively improving the matte effect of thePVC thin film, so that the product is more upscale and beautiful; in addition, the pearlescent PVC thin film cooperates with a pearlescent material, so that the reflection of the pearlescent materialunder light irradiation is more dazzling; and furthermore, the pearlescent PVC thin film is worthy of being promoted.

Description

technical field [0001] The invention belongs to the technical field of polymer compounds, and in particular relates to a pearlescent PVC film and a preparation method thereof. Background technique [0002] The main component of PVC film is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc. PVC film is a kind of synthetic material that is loved, popular and widely used in the world today. The global usage of PVC film ranks second among various synthetic materials. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material. [0003] In the prior art, the production process of pearlescent PVC film is to add pearlescent powder, but this method is not environmentally friendly, and the dispersion of raw materials is poor, the product quality is difficult to control, and the high-end market competitiveness is not strong. Contents of the invention [0004] In order to solve t...
