Water-based alkali-resistant aluminum foil gloss oil and preparation method thereof

Abstract

The invention discloses a water-based alkali-resistant aluminum foil gloss oil. The aluminum foil gloss oil is formed by mixing a component A and a component B according to a weight ratio of 1:1, wherein the component A is prepared from, by weight, 35 to 57 parts of epoxy resin, 16 to 25 parts of urea-formaldehyde resin, 12 to 23 parts of glycerol, 4 to 9 parts of mica powder and 5.6 to 8.8 partsof xanthan gum; and the component B is prepared from, by weight, 29 to 41 parts of polypropylene, 17 to 31 parts of dioctyl phthalate, 11 to 23 parts of tetraisooctyl pyromellitate and 16 to 24 partsof polyether sulfone. The aluminum foil gloss oil is formed by mixing the component A and the component B, under the synergistic effect of various raw materials, the overall alkali resistance can be effectively improved, the environment-friendly characteristic of the water-based gloss oil is reserved, and the aluminum foil gloss oil has high use value and market prospects.

Description

technical field

[0001] The invention relates to the field of coatings, in particular to a water-based alkali-resistant aluminum foil varnish and a preparation method thereof. Background technique

[0002] Aluminum foil varnish is also called aluminum foil varnish. It is essentially a kind of paint, which is to apply varnish on the surface of aluminum foil that has completed all color registration or a single color. It can make the surface of printed products have good gloss, beautiful appearance, and acid and alkali resistance. etc., it can protect the graphic surface and increase the hardness of the product surface.

[0003] Water-based varnish is a new type of environmentally friendly coating, mainly composed of main agent, solvent and auxiliary agent. It is colorless, odorless, transparent, non-toxic, free of organic volatiles, and low in cost. The features such as wide source are unmatched by other solvent-based varnishes. If other main ingredients and auxiliary agents...
