Water-based degradable plastic-replacing gloss oil and preparation method thereof

Abstract

The invention provides water-based degradable plastic-replacing gloss oil and a preparation method thereof. The water-based degradable plastic-replacing gloss oil is prepared from 74%-80% of water-based polyurethane resin, 5%-8% of deionized water, 5%-8% of a water-based coalescing agent, 0.5%-1% of a wetting flatting agent, 3%-5% of polytetrafluoroethylene wax, 1%-2% of an associative thickening agent and 1%-2% of a cross-linking agent; water-based polyurethane resin is taken as a base material, the product is obtained by mixing and blending the water-based coalescing agent, the wetting leveling agent, polytetrafluoroethylene wax, the associative thickening agent and the cross-linking agent in deionized water, and has the characteristics of wear resistance, folding resistance and explosion prevention, is good in adhesion with a base material, free of after-tack and good in cohesiveness, has good glossiness after being oiled, is good in yellowing resistance of a film surface, can be widely applied to medical treatment, electronic equipment, cosmetics and education packaging, and can replace non-degradable products such as film lamination and plastic lamination in the traditional OPP light film process.

Description

technical field [0001] The invention belongs to the technical field of water-based varnish, and in particular relates to a water-based degradable plastic-replacement varnish and a preparation method thereof. Background technique [0002] In the packaging and printing industry, the coating process on the surface of the product makes the product scratch-resistant, waterproof and burst-proof, and is widely used in medical, electronic equipment, cosmetics, and educational packaging. Post-press processing technology, and then non-degradable such as film and plastic in the past, increase the environmental burden. With the implementation of the global plastic restriction order, plastic restriction and ban have become important measures in the process of promoting sustainable development globally. Therefore, at present It is a common expectation in the field of packaging and printing materials to develop an environmentally friendly varnish that can replace plastic films and meet pro...

[0002] In the packaging and printing industry, the coating process on the surface of the product makes the product scratch-resistant, waterproof and burst-proof, and is widely used in medical, electronic equipment, cosmetics, and educational packaging. Post-press processing technology, and then non-degradable such as film and plastic in the past, increase the environmental burden. With the implementation of the global plastic restriction order, plastic restriction and ban have become important measures in the process of promoting sustainable development globally. Therefore, at present It is a common expectation in the field of packaging and printing materials to develop an environmentally friendly varnish that can replace plastic films and meet the performance requirements of product packaging.
