Abstract

The invention discloses a water-based glass high-temperature baking varnish and a preparation method thereof. The water-based glass high-temperature baking varnish comprises a component A, a component B and deionized water in a weight ratio of 100:2:(30-40). The component A comprises the following raw materials in percentage by weight: 40-50 parts of water-based thermosetting acrylic resin, 10-15 parts of amino resin, 0.10-0.50 part of water-based defoaming agent, 0.20-1.00 part of water-based dispersing agent, 0.05-0.20 part of vapor-phase silicon dioxide, 3.3 parts of phthalocyanine blue BGS pigment, 2.86 parts of blue ultramarine pigment, 0.10-0.50 part of substrate wetting agent, 10-20 parts of ethanol, 5-10 parts of propylene glycol monomethyl ether and 1-10 parts of deionized water. Compared with the prior art, by performing the raw material selection and proportioning and the reasonable matching control on parameters in the preparation method, the prepared water-based glass high-temperature baking varnish has the advantages of favorable adhesive force, favorable leveling property, high water resistance and high alcohol resistance.

Description

technical field [0001] The invention relates to the field of coating preparation, in particular to a water-based glass high-temperature baking varnish and a preparation method thereof. Background technique [0002] The coating protection and decoration of glass and glass products have a wide range of needs in industrial and civil fields, such as lighting, wine bottles, perfume bottles, lenses and glass instruments, etc., all need to be coated with protective and decorative coatings on the surface. [0003] Due to the tightening of national environmental protection, the improvement of people's awareness of environmental protection, and the soundness of environmental protection laws and regulations, the original use of epoxy resin for coating the glass surface has been eliminated. In response to market demand, the use of water-based coatings in food packaging and other fields will be irreversible. Replace the original epoxy system. [0004] The single-component water-based gl...
