Abstract

The invention provides an environment-friendly anti-bacterial PVC (Polyvinyl Chloride) thin film. The environment-friendly anti-bacterial PVC thin film is prepared from the following raw materials in parts by weight: 90-110 parts of PVC resin powder, 0.1-0.2 part of lavender essential oil, 20-25 parts of acetyl-tri-n-butyl citrate, 4-8 parts of heat stabilizer and 0.2-0.6 part of lubricant, wherein the heat stabilizer is one or more than one of calcium ricinoleate, calcium stearate, zinc stearate or magnesium stearate, and the lubricant is one or more than one of glyceryl stearate, octadecanamide, paraffin wax and polyethylene wax. The environment-friendly anti-bacterial PVC thin film can be used for inhibiting the breeding of bacteria around the thin film. Compared with a common commercially available thin film, the environment-friendly anti-bacterial PVC thin film has an obvious inhibitory effect on trichoderma viride, escherichia coli and staphylococcus aureus. As the lavender essential oil is a natural plant extraction anti-bacterial agent, the environment-friendly anti-bacterial PVC thin film can be used for a long term and is safe and non-toxic. The acetyl-tri-n-butyl citrate and tri-n-butyl citrate are used as the plasticizers, so that the health problem caused by use of phthalic acid ester-containing plasticizer products can be effectively avoided.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an environment-friendly antibacterial PVC film. Background technique [0002] PVC film is widely used on the surface of floors, ceilings and leather. The top layer of this surface film is paint, the main component of the middle layer is polyvinyl chloride, and the bottom layer is back-coated adhesive. Compared with ordinary veneer films, It can be tightly fused with other boards, and the glue will not be opened for ten or even fifteen years, so it is very popular and has become a widely used synthetic material. [0003] At present, the plasticizers commonly used in the industrial production of PVC films are mainly phthalates. Although this type of plasticizer has good performance, its use has been greatly restricted because of its potential carcinogenic danger. my country has also formulated relevant laws and regulations. The regulations will phase out its application...
