Abstract

The invention relates to the technical field of PVC base materials, and discloses a PVC base material with high gloss and low transmittance. The PVC base material comprises following components in parts by weight: 50 to 300 parts of PVC resin with a polymerization degree of 700 to 800, 1 to 4 parts of a zinc-based tin mercaptide stabilizing agent, 0 to 3 parts of epoxy soybean oil, 1 to 3 parts ofcopolymer of methyl methacrylate and butyl acrylate, 3 to 6 parts of methyl methacrylate polymer, 4 to 9 parts of high-strength MBS, 0.1 to 2.5 parts of an ultraviolet light absorber, 0.6 to 1.5 parts of a lubricating agent and 0.1 to 0.5 part of a pigment. The invention also discloses a preparation method of the PVC base material with high gloss and low transmittance. The preparation method comprises the following steps: S1, hot mixing; S2, cold mixing; and S3, extrusion. The PVC base material is uniform in overall thickness distribution, high in surface gloss, low in transmissivity, durable, and long in shelf life.

Description

technical field [0001] The invention relates to the technical field of PVC base material production, in particular to a PVC base material with high gloss and low transmittance and a preparation method thereof. Background technique [0002] At present, the commonly used pharmaceutical packaging materials in the market include glass, rubber, plastic, and metal materials. Among them, polyvinyl chloride pharmaceutical packaging materials have the advantages of light texture, strong plasticity, beautiful appearance, and easy transportation. They are widely used in tablets, Packaging of solid preparations such as capsules, pills, and granules. However, during the circulation process, drugs are easily decomposed and deteriorated due to the influence of the surrounding environment such as light. After the drugs are processed and shaped, appropriate packaging must be selected to maintain the efficacy of the drugs, improve the stability of the drugs, delay the deterioration of the dru...
