Problems solved by technology

[0003] At present, the plasticizers commonly used in the industrial production of PVC films are mainly phthalates. Although these plasticizers have good performance, they are harmful to the human body due to their potential carcinogenicity.
Moreover, the traditional PVC film lacks antibacteria

Embodiment 1

[0014] A bacteriostatic PVC film, comprising the following raw materials in parts by weight: 100 parts of PVC resin powder, 0.1 part of Angelica dahurica essential oil, 22 parts of acetyl tri-n-butyl citrate, 2 parts of mercaptan methyl tin stabilizer, hard Zinc fatty acid 0.5 part.

Embodiment 2

[0016] A bacteriostatic PVC film, comprising the following raw materials in parts by weight: 120 parts of PVC resin powder, 0.5 part of Angelica dahurica essential oil, 28 parts of acetyl tri-n-butyl citrate, 5 parts of mercaptan methyl tin stabilizer, hard Zinc fatty acid 1 part.

Embodiment 3

[0018] A bacteriostatic PVC film, comprising the following raw materials in parts by weight: 110 parts of PVC resin powder, 0.3 parts of Angelica dahurica essential oil, 25 parts of acetyl tri-n-butyl citrate, 4 parts of mercaptan methyl tin stabilizer, hard Zinc fatty acid 0.8 part.

[0019] Detection and analysis of antibacterial performance of this product:

[0020] Place 100 films of the present invention whose specifications are 0.5cm×1cm in the bacterium liquid of mucormycetes, and after shaking and cultivating at room temperature for 3 hours, take 2 drops of the culture solution to measure the number of spore germination with a microscope, and calculate the spore germination rate; under the same conditions, With common PVC film as contrast, obtain the bacteriostasis effect of embodiment 1~3, the results are shown in Table 1.

Abstract

The invention relates to a bacteriostatic PVC film, and belongs to the field of polymer materials. The bacteriostatic PVC film comprises the following raw materials: by weight, 100-120 parts of PVC resin powder, 0.1-0.5 parts of angelica essential oil, 22-28 parts of acetyl-tri-n-butyl citrate, 2-5 of a heat stabilizer, and 0.5-1 part of a lubricant. The bacteriostatic agent used in the bacteriostatic PVC film is a pure natural plant-extracted bacteriostatic agent, can inhibit breeding of bacteria around the film, to provide a healthy environment for people. At the same time, the bacteriostatic PVC film uses the acetyl-tri-n-butyl citrate as a plasticizer, health problems caused by the use of plasticizer products containing phthalate esters can be effectively avoided.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a bacteriostatic PVC film. Background technique [0002] The essence of PVC film is a vacuum blister film. The top layer of PVC film surface is paint, the main component of the middle layer is polyvinyl chloride, and the bottom layer is back-coated adhesive. Compared with ordinary veneer film, it can be compared with other The boards are tightly fused together, and the glue will not be opened for ten or even fifteen years, so it is deeply loved by people and has become a widely used synthetic material for the surface packaging of various panels, so it is also called decorative film. , Attached film. [0003] At present, the plasticizers commonly used in the industrial production of PVC films are mainly phthalates. Although these plasticizers have good performance, they are harmful to the human body due to their potential carcinogenicity. Moreover, the traditional PV...
