Problems solved by technology

However, the adhesion of the transfer film on the artificial stone is not very good, and it is prone to problems such as falling off, cracking, and wrinkling. In order to improve the decorative effect on artificial stone products, a layer of transparent protective paint must be sprayed on the surface of the artificial stone with a graphic layer

Abstract

The invention relates to an ultrahigh-water-resistance coating varnish for artificial stone water transfer printing, and preparation and application methods thereof. The main paint comprises the following components in parts by weight: 50-60 parts of synthetic fatty acid modified alkyd resin, 20-25 parts of lauric acid modified alkyd resin, 5-8 parts of aldehyde ketone resin, 2-5 parts of nano vapor-phase silicon dioxide slurry, 4-8 parts of solvent, 0.3-0.5 part of defoaming agent, 0.05-0.3 part of drying agent, 0.2-0.5 part of leveling agent and 1-3 parts of adhesion promoter. The application method comprises the following steps: weighing the coating varnish, uniformly stirring the auxiliary paint, main paint, curing agent and diluter in a weight ratio of 1:(0.8-1.0):(0.8-10), spraying on a substrate, and naturally drying.

Description

technical field [0001] The invention relates to a paint, in particular to a super water-resistant finish varnish for artificial stone water transfer printing and a preparation method and application method thereof. Background technique [0002] With the continuous development of science and technology and people's demand for the beauty of product appearance, the application of water transfer printing technology in various automotive supplies, electronic products, daily necessities, handicrafts, and interior building doors and windows, floors, bathrooms, etc. bigger and bigger. Many of these products are made of artificial stone. However, the adhesion of the transfer film on the artificial stone is not very good, and it is prone to problems such as falling off, cracking, and wrinkling. In order to improve the decorative effect on artificial stone products, a layer of transparent protective paint must be sprayed on the surface of the artificial stone with a graphic layer. ...
