Abstract

The invention relates to a mildew-proof PVC film and a production method thereof. The mildew-proof PVC film is specifically prepared from the following components in parts by mass: 60-80 parts of PVC,10-30 parts of 7 type PVC, 10-15 parts of calcium powder, 2-5 parts of ESO, 35-45 parts of DPHP, 1-2 parts of BS-105, 1-2 parts of a special mildew preventive, 1-2 parts of R-666, 0.002-0.005 part of5007, 0.005-0.01 part of 3214, 0.02-0.03 part of 8793, 0.2-0.5 part of 736A and 0.5-1 part of a flame retardant. Compared with a commercially available mildew-proof PVC film, the mildew-proof PVC film disclosed by the invention has the advantage of long-term mildew prevention and has high market competitiveness.

Description

technical field [0001] The invention belongs to the technical field of polymer compounds, and in particular relates to a mold-proof PVC film and a production 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 anti-mold PVC film is to add common anti-mold agent, but this method is easily affected by the dispersion effect of anti-mold agent, and long-term use will lead to the decline of its anti-mold effect. Contents of the invention [0004] In order to solve the above problems, the invention provides a mi...
