Production method of environment-friendly water-soluble gum electrochemical aluminothermic transfer printing film

Abstract

The invention relates to a production method of an environment-friendly water-soluble gum electrochemical aluminothermic transfer printing film. The production method comprises the following steps: a PET film of 6 to 15 micron is adopted as a carrier film; the carrier film is sequentially provided with four coatings such as a releasing layer, a color layer, an aluminum layer and an adhesive layer; wherein the releasing layer, the color layer and the adhesive layer coat the coating materials on a PET basal membrane substrate by a smooth roll or an anilox roll in a forward coating mode or backward coating mode; the aluminum layer is spray-plated in a vacuum spray-plating mode; the invention adopts the environment-friendly material and the production technique to produce the aluminothermic transfer printing film product, and the key points are as follows: solvent based acrylic resin, ethylene-vinyl acetate resin, ketone resin and cellulosic resin hot melt adhesive are changed into cellulose acetate and products made by cellulose acetate; and vinyl cellulose, polyvinyl butyral and powdery silicon dioxide are synthesized by water and a mixed solvent in a mode of wetting and dispersing. The production method has the characteristics of having no solvent residue harmful to human body and being beneficial to environmental protection and the like.

Description

technical field [0001] The invention relates to an environment-friendly water-soluble self-adhesive anodized aluminum thermal transfer film and a production method thereof. Background technique [0002] Most of the anodized aluminum products on the market now use organic solvent-based adhesives, mainly composed of one or more of acrylic resins, ethylene vinyl acetate resins, ketone resins, and cellulose resins. The characteristics of their use are: use organic solvent-based adhesives There is a certain amount of solvent residues in the electrochemical aluminum products; these solvent residues are not good for human health; they also do not meet the needs of the current situation where the whole society is calling for "green" and "environmental protection". Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide an environmentally friendly water-soluble self-adhesive anodized aluminum heat transfe...
