Problems solved by technology

[0003] Water-based industrial coatings are mainly used in automobiles, railway vehicles, bridge pipes, steel structures, containers and other fields. At present, there is a big gap in the water-based level and technology of domestic industrial coatings compared with industrial developed countries. Water-based paints have insufficient film hardness. High, easy to scratch, poor chemical resistance, low solid content, etc.

Embodiment

[0024] Industrial anti-corrosion water paint is a two-component water-based paint, which is composed of A component and B component. The first two components are stored separately. During construction, the A component and B component are in a weight ratio of 3 to 5:1 Mix and serve.

[0025] Component A is mainly composed of base material, additives and pigments and fillers. The base material is water-based polyurea resin, using polyaspartate resin of model F420 from Shenzhen Feiyang Industrial Co., Ltd. and polyurethane polyurea resin of model Desmophen N1420 from Bayer, Germany, mixed according to the weight ratio of 2:1 be made of.

[0026] Component B is an aliphatic polyisocyanate-type solvent-free curing agent, which is a product of Desmodur N 3300 from Bayer, Germany.

[0027] Weigh the base materials, additives and pigments and fillers in different proportions by weight to produce component A, and the specific proportions are shown in Table 1 below.

Abstract

The invention relates to the technical field of coatings, in particular to the technical field of water-based anti-corrosive coatings and discloses a chemical-resistant industrial anti-corrosive water paint. The chemical-resistant industrial anti-corrosive water paint is prepared by mixing a component A and a component B; the weigh ratio of the component A to the component B is (3-5):1; the component A comprises the following components in parts by weight: 30-50 parts of water-based polyurea resin, 2-8 parts of an environment-friendly solvent, 0.5-1 part of a neutralizing agent, 0.5-2 parts of a wetting and dispersing agent, 0.1-0.5 part of a de-foaming agent, 15-25 parts of titanium dioxide, 5-10 parts of precipitated barium sulphate, 3-8 parts of talcum powder and 3-5 parts of nano diatomite; the component B is a solvent-free curing agent. The anticorrosive water paint disclosed by the invention is excellent in chemical resistance, has the advantages of being high in solid content, good in scratch resistance, high in hardness and low in organic volatile matter content and has a small impact on environment and physical health of construction personnel.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to the technical field of water-based anticorrosion coatings. Background technique [0002] Water-based coatings use water as a solvent or as a dispersion medium, and have developed rapidly in recent years. The pollution caused by volatile organic compounds (VOC) released during the production and use of traditional solvent-based paints has become the main source of pollution in cities after cars. Water-based paints, as one of the alternatives to traditional solvent-based paints, can Reduce VOC emissions, waste generation, and reduce workers' exposure to toxic emissions. In the future, my country plans to strengthen the control of the total amount of VOC, and carry out coordinated emission reduction of nitrogen oxides and VOC. [0003] Water-based industrial coatings are mainly used in automobiles, railway vehicles, bridge pipes, steel structures, containers and other fields. At ...
