Problems solved by technology

The migration of plasticizer will reduce the physical properties of the product, make the product hard and brittle, and obviously damage the surface properties of the product, seriously affecting the performance and service life of the product
On the other hand, when the plasticizer in PVC products migrates outward, it will also cause harm to human health and the ecological environment.
[0006] All in all, plasticizers, formaldehyde absorbents and other substances added to traditional PVC products are easy to migrate, and their performance is unstable, and the products cannot maintain their mechanical properties for a long time.

Abstract

The invention relates to a preparation process of a PVC (Polyvinyl chloride) decorative film. The preparation process comprises the following steps: mixing PVC resin, a polyurethane elastomer, a plasticizer, a stabilizer, pigments, titanium dioxide, light calcium carbonate and dicumyl peroxide, and performing internal mixing, open milling, extrusion filtering, four-roll calendaring, pulling, embossing, cooling, trimming and coiling, thereby obtaining the decorative film. The decorative film has an excellent formaldehyde absorption effect, and the plasticizer is less in migration and stable inperformance.

Description

technical field [0001] The invention relates to the field of PVC, in particular to a preparation process of a decorative PVC film. Background technique [0002] With the gradual improvement of people's living standards and the rise of the real estate industry, surface decoration materials have entered a period of rapid development. Among them, film materials such as PVC film, PET film and composite film have simple production processes, various surface decoration patterns and effects, and use methods. Simple and cost-effective, it occupies a dominant position in the new surface decoration material market. PVC film has good wear resistance, good corrosion resistance, high quality and low price, and is developing rapidly. It is widely used in indoor and furniture decoration, decoration industry, aircraft interior membrane, cabin membrane and other fields. It can make the surface of the decorated object obtain higher hardness, prevent the surface from being artificially scratc...
