Problems solved by technology

[0003] Powder coatings or liquid coatings are usually used for coating on the surface of hardware and furniture. Since hardware and furniture are people’s daily contact, it is required to limit the content of heavy metals in coatings to prevent people from being poisoned by heavy metals. However, most of the existing powder coatings and Liquid coatings basically contain a small amount of heavy metals, which are closely related to the strength, flexibility, adhesion, abrasion resistance and alcohol resistance of the coatings. Therefore, many existing coatings have the risk of heavy metal poisoning. Potential hazards, and there are also potential pollution hazards to the environment

Abstract

The invention relates to environment-friendly water-borne acrylic-modified epoxy baking varnish. The backing varnish consists of the following components in parts by weight: 15-18 parts of dipropylene glycol methyl ether, 0.5-0.7 part of isopropanol, 6-8 parts of amino resin, 42-44 parts of water-borne acrylic-modified epoxy resin, 0.6-1.1 parts of dispersant, 0.2-0.5 part of defoaming agent, 0.45-0.55 part of flatting agent, 0.35-0.45 part of PH regulator, 30-36 parts of white slurry, 2-4 parts of deionized water and 0.1-0.2 part of thickening agent. The environment-friendly water-borne acrylic-modified epoxy baking varnish has the advantages of high modulus, high strength, high toughness, excellent wear resistance and alcohol resistance and the like, so that the performances of the baking varnish are changed; in addition, the prepared environment-friendly water-borne acrylic-modified epoxy baking varnish does not contain any heavy metals harmful to a human body and the environment and is innocuous and harmless; the body health of people is protected, and meanwhile, the surrounding environment is protected from being polluted.

Description

technical field [0001] The invention relates to a baking varnish, in particular to an environment-friendly water-based acrylic modified epoxy baking varnish. Background technique [0002] Baking varnish is a new method (process) of spraying paint in furniture manufacturing. The method is: spray several layers of paint on a substrate (usually a high-density board) that has been polished to a certain degree of roughness, and bake it at a high temperature to finalize the shape. . At present, this process has higher requirements on paint and good color rendering. The baking varnish process has been widely used in furniture products such as sliding doors, cabinets and desks, and it has also begun to penetrate into surface processing processes of other materials. Baking varnish is divided into two categories, one is low-temperature baking varnish with a curing temperature of 90°-100°, and the other is called high-temperature baking varnish with a curing temperature of 230°-240°....
