Abstract

The invention discloses an environment-friendly PVC (polyvinyl chloride) decorative film which comprises an environment-friendly PVC substrate, a water-based ink printing layer printed on the environment-friendly PVC substrate, and an environment-friendly PVC mask attached to the water-based ink printing layer. The water-based ink is an inorganic nano modified acrylate composite paint which is mainly prepared from 18-22 parts of nano silicon dioxide acrylate composite emulsion, 42-55 parts of self-crosslinked styrene-acrylic emulsion, 20-32 parts of high-solid-content pigment filter cake, 0.3-1 part of anionic surfactant and the like. The environment-friendly PVC decorative film has the advantages of favorable staining power, high drying speed, favorable film forming property, high adhesive force, no toxicity or smell, favorable heat stability and the like. The invention also discloses a preparation method of the environment-friendly PVC decorative film. The preparation method has the advantages of simple production technique and high practicality, and is beneficial to industrial production.

Description

technical field [0001] The invention relates to a PVC decorative film, in particular to an environment-friendly PVC decorative film and a preparation method thereof. Background technique [0002] As people's demand for home decoration is increasing, more and more attention is paid to environmentally friendly materials. The traditional decorative film in the household industry uses PVC film as the base material, and uses solvent-based ink to print the decorative layer. In order to improve the performance of PVC film as a printing substrate and laminating mask, if the PVC film is required to have high transparency, high strength, low and high temperature resistance, good self-adhesiveness, and certain oxygen and moisture permeability, etc., it is necessary to add a large amount of Plasticizers, stabilizers, and a certain amount of monomers and decomposition products will remain during the production of PVC film. These decomposed chlorinated products will form unpleasant odors...
