Water paint formula

Abstract

The invention discloses a water paint formula, belongs to the technical field of anticorrosive paints, and particularly relates to an environment-friendly water paint formula which comprises the following raw materials in parts by weight: 16 to 20 parts of water-based alkyd resin; 4 to 8 parts of ethylene glycol monobutyl ether; 1 to 5 parts of 1-methoxy-2-propanol; 1.6 to 2 parts of dimethylethanolamine; 0.5 to 1 part of a drier; 0.3 to 0.6 part of an antirust agent; 30 to 40 parts of water; 0.3 to 0.6 part of a defoaming agent; 0.1 to 0.5 part of a wetting agent; 0.2 to 0.5 part of a defoaming agent; 4-8 parts of iron oxide red powder; 11 to 15 parts of ferrotitanium powder; 11 to 15 parts of high-gloss barium sulfate; 0.3 to 0.6 part of a flash rust inhibitor; and 1 to 2 parts of triethylamine. Paint sprayed and coated according to the water paint formula is good in stability, flat and smooth in surface, high in hardness, free of toxic metal compounds, low in VOC content and excellent in physical and chemical performance, and has the advantages of being high in adhesive force and adhesive force, good in waterproof effect, non-toxic, environmentally friendly, low in cost and widein application range.

Description

technical field [0001] The invention belongs to the technical field of mechanical coating anticorrosion paint, in particular to a water paint formula. Background technique [0002] Water-based paint is a paint that uses water as a thinner. It has the characteristics of energy saving and environmental protection, non-flammable and non-explosive, ultra-low emission, low-carbon health, etc., and the paint film is full, good flexibility, water resistance, wear resistance, aging resistance, yellowing resistance, easy to use, and can be widely used in wood, metal, Industrial coating, plastic, glass, building surface and other materials. Water-based paint is an updated product that gradually replaces paint, and the promotion of water-based paint is a revolution in the paint field. [0003] Now there are endless water paints on the market, with more and more varieties, and various performances and functions. There are two main categories: water-based and oil-based. The oily type...

Problems solved by technology

Solvent-based paints for mechanical equipment have problems such as high content of volatile organic compounds, serious pollution, and certain fire hazards.

The VOC of existing water-based paint products still cannot meet the requirements, and the product’s chemical properties such as heat and humidity resistance and salt spray resistance are inferior to those of solvent-based paints. The large-scale industrialized continuous production required is limited in scale, and in order to improve anti-corrosion performance, it is often necessary to add some anti-rust pigments with heavy metals, which reduces environmental protection and safety, and lower international competitiveness

[0005] The existing domestic high-corrosion and high-weather-resistant mechanical equipment special water-based paints are difficult to meet the requirements of weather resistance, safety performance, and anti-corrosion performance.
