AI Technical Summary

Technical Problem

The existing decorative layer manufacturing methods for decorative materials pattern have the waste of using alcohol organic solvents and carrier layers in watermarking technology, and the skinning technology leads to environmental pollution and poor water resistance of the product.

Method used

A water-soluble polyvinyl alcohol pattern film is used, which includes a carrier layer, a pattern layer and a pattern protective layer. Through the combination of gel reversible polyvinyl alcohol film, aqueous polyvinyl alcohol pattern ink and transparent printing liquid, no pattern decoration without harmful gas release and wastewater and waste residue are achieved.

Benefits of technology

The pattern decoration process is realized completely with water as the solvent, which reduces the cost of use and environmental pollution, increases the thickness of the pattern layer and anti-corrosion and scratch resistance, and solves the waste problem of the carrier layer.

Abstract

The present invention discloses a water-soluble polyvinyl alcohol pattern film, which is characterized in that: the pattern film comprises a carrier layer, a pattern layer and a pattern protection layer; the carrier layer is made of a gel reversible polyvinyl alcohol film; the pattern layer is made by printing polyvinyl alcohol pattern ink; and the pattern protection layer is made by printing polyvinyl alcohol transparent printing liquid. The water-soluble polyvinyl alcohol pattern film of the present invention uses water as a solvent during use and has no harm to the environment. The method of use is simple, the labor cost is low, and the equipment investment is small. The application range is wide, and it is suitable for artificial marble manufacturing, glass products and military equipment camouflage mapping. It solves the environmental pollution caused by adhesives and pasting patterns in the building decoration industry.
