Abstract

The invention relates to an aqueous metal antirust paint and its application method. According to the invention, aqueous epoxy hybrid resin and acrylic acid hybrid resin are used as main materials, and a wetting agent, a leveling agent, an antifoaming agent, a thickening agent, water, an epoxy hardener, triethylamine and the like are used as auxiliary materials. All the above materials undergo stirring, dispersion, mixing, spraying, self-drying, cooling, examination and packaging so as to prepare the aqueous metal antirust paint. In comparison with a traditional oil metal antirust paint, the aqueous metal antirust paint provided by the invention has characteristics of excellent comprehensive performance, good antirust property and waterproofness, strong adhesion, high hardness, great impact resistance and the like. By the adoption of the antirust paint, anticorrosion performance of metal surface is greatly improved. The antirust paint provided by the invention has stable quality, is easy to package, transport and store, is moistureproof and antifreezing, will not breed bacteria or microbes, and is applicable to metal antirust spare and accessory parts in ship industry, automobile industry and the like.

Description

technical field [0001] The invention relates to an antirust paint, in particular to a novel environmental-friendly water-based metal antirust paint that can be sprayed, rolled and brushed and its application method. Background technique [0002] Traditional oil-based metal antirust paint also contains a large amount of toxic carcinogens such as formaldehyde and benzene, which has become the "number one killer" that pollutes the environment and damages the health of consumers. Experts pointed out that in order to minimize the highly toxic pollution of paint in home decoration, you should try to avoid using solvent-based paint, and you should choose more environmentally friendly and safer water-based paint. [0003] my country has also formulated some laws and regulations since the 1980s. Such as: "Environmental Law", Shanghai local standard "Healthy Building Interior Wall Coatings" (DB31 / T15-1998), national mandatory standards (indoor decoration materials, limit of harmful s...
