Abstract

The invention relates to a photosensitive water-soluble coating and a preparation method thereof, belonging to the technical field of coating. The photosensitive water-soluble coating comprises the following active ingredients in parts by weight: 100-120 parts of photosensitive novolac epoxy acrylic resin, 2-5 parts of photoinitiator EDAB, 1-2 parts of isopropylthioxanthone, 18-25 parts of ethoxylated trimethylolpropane triacrylate, 3-6 parts of ammonium hydroxide, 2-5 parts of thickener, 1-3 parts of zinc stearate, 0.5-2 parts of antibacterial agent, 5-8 parts of acetone, and 30-50 parts of water. The preparation method is simple, the prepared photosensitive water-soluble coating is strong in adhesive force, good in high temperature resistance property, and excellent in antibacterial property; by mainly taking water as a solvent, the pollution of the solvent type coating on the environment can be overcome, thus the photosensitive water-soluble coating is a green and environment-friendly coating and is worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a photosensitive water-soluble coating and a preparation method thereof. Background technique [0002] After more than half a century of development of ultraviolet (UV) curing coatings, UV curing coatings have become a relatively mature technology, especially with the improvement of people's environmental awareness, production and researchers pay more attention to the development and application of UV curing coatings. UV curing coating is a kind of green and environment-friendly coating, which fully complies with the "4E" principle. Generally, the energy consumption of UV curing is 1 / 5 of that of thermal curing, and UV curing coating contains less volatile components and less pollution. It is most attractive to researchers. And the developer's advantage is that UV curing coatings can reduce raw material consumption, which is beneficial to reduce economic costs. [0...
