Waterborne alkyd enamel paint and preparation method thereof

Abstract

The invention provides waterborne alkyd enamel paint and a preparation method thereof. The waterborne alkyd enamel paint mainly comprises, by weight, 18-45 parts of waterborne alkyd resin, 2.1-8.3 parts of waterborne auxiliaries, 1.9-6.5 parts of pigment, 5-10 parts of fillers and 5-70 parts of water. The waterborne alkyd enamel paint takes water to serve as a thinning agent, different types of waterborne alkyd resin is reasonably blended, the waterborne auxiliaries and the fillers serve as scientific components and are added, the raw materials are mixed, so that high-molecular linear polymers are cross-linked into a meshed macromolecular structure, anti-rusting properties, water tolerance and mechanical properties of the waterborne alkyd enamel paint are improved, the waterborne alkyd enamel paint is low in odor, organic solvents such as benzene and dimethyl benzene are omitted, hazards on human health are avoided, organic matters are less in volatilization in the construction process, and potential safety hazards such as fire disasters are avoided.

Description

technical field [0001] The invention relates to the technical field of coating chemicals, in particular to a water-based alkyd enamel and a preparation method thereof. Background technique [0002] With the enhancement of people's awareness of environmental protection and the improvement of health attention, the requirements for the safety of coatings are becoming more and more stringent. Most steel structure manufacturers in the market still use traditional oil-based alkyd enamel. It contains benzene, xylene and other organic solvents, which will cause great damage to the environment and human health. Therefore, using water-based resin as the main film-forming material and using water as a diluent, the water-based alkyd enamel prepared has low volatile organic content, low odor, low toxicity, and excellent performance. It is currently the largest type of coating in China. Widely used in steel structures, automobile chassis parts, steel pipes, metal mechanical equipment, fu...

AI Technical Summary

Problems solved by technology

The water-based alkyd enamel uses water as the diluent, and uses different types of water-based alkyd resins for reasonable deployment, and adds scientific components of water-based additives and fillers. After mixing and stirring, the high-molecular linear polymers are cross-linked into network-like macromolecules structure, improve its rust resistance, water resistance, mechanical properties, etc., and solve the problems that the water-based alkyd enamel in the prior art is slow to dry, and the water resistance and mechanical properties after coating are not easy to meet higher requirements.
