Abstract

The invention relates to the field of ink and in particular provides mirror surface silver ink as well as a preparation method and a product thereof. Due to adoption of an aqueous acrylic acid modified polyester resin in the mirror surface silver ink, the chemical resistance of a mirror surface silver ink coating can be improved; due to adoption of an aqueous stoving varnish epoxy resin, the alkali resistance of the mirror surface silver ink coating can be improved; due to adoption of an aqueous sealed isocyanate curing agent and an aqueous benzene amino resin, the crosslinking density of rawmaterials can be improved; a modified silane coupling agent can be directly used in the mirror surface silver ink, storage stability of the mirror surface silver ink is not affected, and meanwhile thewater resistance and the binding force of the ink coating with a substrate can be improved; the mirror surface silver ink is harmless to human bodies and environments, a protection layer is not needed, and effects that no silver is peeled, adhesion is not affected and a mirror surface effect is not affected can be achieved when a single coating layer is washed with 4% NaOH at 70 DEG C.

Description

technical field [0001] The invention relates to the field of inks, in particular to a mirror silver ink, a preparation method and a product thereof. Background technique [0002] Mirror silver ink is made of mirror silver, a small amount of resin and a special thinner as the basic material. It is screen-printed on the back of the transparent sheet, and has the glossy effect of a mirror or bronzing surface when viewed from the front. Mirror silver ink has excellent covering property, and has the same mirror effect as silver vapor-deposited sheet. [0003] Since most of the mirror silver on the market at this stage is an oily system, the resins, diluents and additives in the ink are all solvent-based. Screen printing requires the ink to be as thin as water, so a large amount of diluent needs to be added, resulting in high VOC content and great pollution to the environment. At the same time, there are steps such as boiling water, alkali treatment and ultrasonic cleaning in th...
