Abstract

The invention discloses a production process of a PVC decorative film. The production process comprises the specific steps that a PVC surface layer is pressed and attached to a PVC substrate coated with mixed liquid, the used mixed liquid is prepared with, by weight, 28-32 parts of amino modified acrylic acid, 2-4 parts of sodium fatty alcohol sulfate, 5-8 parts of an acrylate leveling agent with the molecular weight being 10, 000 or below, 3-5 parts of PEG-4 isostearate and 3-5 parts of water, and the weight of the amino modified acrylic acid is 2.5-3.5 times of the sum of the weight of the acrylate leveling agent with the molecular weight of 10, 000 or below and the weight of the PEG-4 isostearate. Due to coating with the mixed liquid, the rolling effect and interaction force between the PVC substrate and the PVC surface layer can be improved, and the friction resistance of the PVC decorative film is improved.

Description

technical field [0001] The invention relates to the technical field of PVC decorative film preparation, in particular to a production process of PVC decorative film. Background technique [0002] PVC decorative film can be widely used in home decoration, home appliances, furniture, automotive interiors and other fields because of its advantages of easy use and replacement, various colors, and low cost. However, it has been found in the long-term use of PVC decorative films that PVC decorative films are easily damaged after being wiped many times. In the prior art, the surface treatment agent is often used to improve the adhesion of PVC decorative film and improve the friction resistance. However, after reference and trial of the existing technology, the products prepared by the process equipment in the factory have no effect after testing. Ideal. Therefore, it is necessary to develop a preparation process that is suitable for the factory's own production and can improve th...
