Embodiment 1

[0038] At first, carry out step (1): add the DINP of 20 mass parts, the epoxy soybean oil of 2 mass parts, the liquid stabilizer of 2 mass parts and the ultramarine blue pigment of 0.01 mass part in every 100 mass parts of polyvinyl chloride; Oxygenated soybean oil has an epoxy value≧6.6 and an iodine value≦3.0. The DINP and epoxy soybean oil used in this embodiment are to make the prepared cold lamination film have higher tensile properties and wear resistance. The preferred epoxidized soybean oil used in this embodiment is hydroxyl epoxidized soybean oil. Hydroxylated soybean oil is obtained by reacting epoxy soybean oil with adipic acid under the action of N,N-dimethylbenzylamine. Compared with ordinary epoxy soybean oil, hydroxyl epoxy soybean oil can improve the tensile performance and wear resistance of the prepared cold lamination film. After calculation, the number of wear resistance can be increased by 20%.

[0039] Furthermore, the liquid stabilizer used in this embo...

Embodiment 2

[0051] The difference between the production process of a transparent cold-mounted PVC calendered film involved in this embodiment and Example 1 is that in step (1), 23 parts by mass of DINP, 4 parts by mass of Epoxidized soybean oil, 3 parts by mass of liquid stabilizer and 0.03 parts by mass of ultramarine blue; the epoxy value of the epoxidized soybean oil is ≧6.6, and the iodine value≦3.0. Step (2) The raw materials of each component were first stirred at a high speed of 95°C for 330s, and then stirred and mixed evenly at room temperature.

Embodiment 3

[0053] The difference between the production process of a transparent cold-mounted PVC calendered film involved in this embodiment and the first embodiment is that in step (1), 25 parts by mass of DINP, 5 parts by mass of Epoxidized soybean oil, 5 parts by mass of a liquid stabilizer and 0.05 parts by mass of ultramarine blue; the epoxy value of the epoxidized soybean oil is ≧6.6, and the iodine value≦3.0. Step (2) The raw materials of each component are first stirred at a high speed at 100°C for 300-350s, and then stirred and mixed evenly at room temperature.

Abstract

The invention relates to a production process of a transparent cold laminating PVC calendering film. The preparation method comprises: uniformly mixing PVC, DINP, a liquid stabilizer, epoxidized soybean oil and other raw materials, carrying out plasticizing treatment on the cooled mixture, filtering, carrying out calendering forming by adopting a five-roller calender, embossing, and cooling to obtain a transparent cold laminating PVC calendering film by combining with proper process parameters, so that the plasticizing effect of the surface of the cold laminating film is improved, the uneven phenomenon of the surface of the cold laminating film is reduced, and the transparency of the cold laminating film is improved. According to the invention, the mounting film has good combinability withwater-based ink.

Description

technical field [0001] The invention relates to the technical field of PVC calendered film production, in particular to a production process of transparent cold-mounted PVC calendered film. Background technique [0002] Cold lamination film is made of transparent PVC through adhesive processing. According to the texture of the film surface, it can be divided into light film, matte film, frosted film, star illusion film, laser film and protective film with special texture. It is widely used in advertising production. The most popular are glossy film, matte film and frosted film. The cold lamination film is laminated on the picture printed by hand or by a cold laminator to prevent the picture (printing surface) from being scratched, polluted or wet, and to protect the picture. The surface of the cold lamination film usually needs to be sprayed on the surface to improve the display effect of the picture. However, the cold lamination film in the prior art has the problem of poo...
