Embodiment 1

[0025] Environmentally friendly PVC film, including the following raw materials in parts by mass: 90 parts of PVC resin powder, 0.1 part of lavender essential oil, 30 parts of synthetic vegetable ester, 4 parts of calcium ricinoleate, and 0.2 part of glyceryl stearate.

[0026] The preparation method of the lavender essential oil is as follows: take 20g of lavender flowers, crush them and pass through a 60 mesh sieve, place them in a 250mL beaker, add 150mL of n-hexane, soak for 30min, place them in an ultrasonic instrument, ultrasonicate for 60min at 40°C, and cool to room temperature.

[0027] Temperature, distillation under reduced pressure, the concentrated solution is lavender essential oil.

[0028] The preparation method of the present invention: add 90 parts of PVC resin powder, 0.1 part of lavender essential oil, 30 parts of synthetic vegetable ester, 4 parts of calcium ricinoleate and 0.2 part of glyceryl stearate into a high-speed mixer and heat up to 80 °C according...

Abstract

Environmentally friendly PVC film, including the following raw materials in terms of parts by mass: 90-110 parts of PVC resin powder, 0.1-0.2 parts of lavender essential oil, 20-25 parts of synthetic vegetable ester, 4-8 parts of heat stabilizer, and 0.2-0.6 parts of lubricant part, the heat stabilizer is one or more kinds of monostearic acid in calcium ricinoleate, calcium stearate, zinc stearate or magnesium stearate, and the described lubricant is glyceryl stearate, One or more of amine, paraffin, polyethylene wax. The present invention can inhibit the growth of bacteria around the film. Compared with ordinary commercially available PVC films, it has a significant inhibitory effect on Trichoderma viridans, E. It is safe and non-toxic, and the present invention uses synthetic vegetable esters and tributyl citrate as plasticizers, which can effectively avoid health problems caused by using products containing phthalates plasticizers.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an environment-friendly PVC film. Background technique [0002] PVC film is widely used in floors, ceilings and leather surfaces. 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 these plasticizers have good performance, their use has been greatly restricted because of their potential carcinogenic risks. my country has also formulated relevant laws and regulations. The regulations will phase out its application in food packaging mat...
