Problems solved by technology

According to daily life, small metal surfaces such as clothing zippers, zipper pullers, buckles, shoe buckles, etc. will be sprayed with a layer of paint on the surface for aesthetics and anti-rust, but these small hardware decorations will touch the skin. Paint spraying will not only cause adverse effects such as skin allergies, but also damage the environment during the paint production process. Therefore, a water-based hardware paint that is harmless to the human body is needed

Abstract

The invention relates to a waterborne automatically spraying paint for ironware and a preparation method thereof. The waterborne automatically spraying paint comprises a component A and a component B.The component A comprises, by weight, 1.5-2.5 parts of waterborne fatty amine, 0.05-0.15 part of a waterborne pH adjusting agent and 0.4-1.2 parts of purified water. The component B comprises the following components by weight: 0.2-0. 8 part of a waterborne epoxy resin emulsion, 1-1.5 parts of a waterborne acrylic emulsion, 0.02-0.1 part of a waterborne dispersion, 0.02-0.1 part of a waterborne leveling agent, 0.01-0.03 part of a waterborne antifoaming agent, 0.1-0.2 part of a filling material and 0.5-1.5 parts of purified water. In use, the component A and the component B is uniformly mixedaccording to a mass ratio of (1-5): 1 before construction. The waterborne automatically spraying paint of the invention has the beneficial effects of no harm to human beings and friendliness to environment.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a water-based hardware automatic spray coating and a preparation method thereof. Background technique [0002] Paint refers to a continuous film that is coated on the surface of the object to be protected or decorated, and can form a firm adhesion with the object to be coated. It is usually based on resin, oil, and emulsion, with or without adding pigments and fillers. Additives, viscous liquids prepared with organic solvents or water. At present, oily epoxy two-component coatings are used for spraying at home and abroad. Because oily epoxy coatings contain harmful components such as bisphenol A and chloropropane, they cause skin allergies and have carcinogenic effects. During the production process, the discharge of volatile organic compounds (VOCs) in wastewater seriously exceeds the standard, which is flammable and explosive, and there are potential safety hazard...
