Problems solved by technology

On the one hand, most water-based alkyd products in the market are water-soluble, that is, on the basis of traditional alkyd resins, use trimellitic anhydride or maleic anhydride to control the acid value at 40-60 mgKOH / g, and then add 30-40% glycol ether or Diluted with butanol organic solvents, and finally neutralized with toxic amines, resulting in high resin viscosity, slow drying of the coating film, low hardness, resistance to hydrolysis, and storage stability of the finished paint; on the other hand, organic The health hazards of volatile substances to people are increasing day by day, causing the haze weather to increase gradually. With the progress of society, the continuous improvement of people's environmental requirements and the continuous improvement of environmental protection standards and regulations, environmentally friendly green coatings with low VOC and air pollutants It has increasingly received people's attention and has developed rapidly

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an alkyd phase-inversion emulsion and its preparation method and application. Background technique [0002] Alkyd coatings have excellent technological properties, mechanical properties and physical properties, and are widely used in the fields of mechatronics, aviation, transportation and construction. [0003] Currently, traditional alkyd resins are water-insoluble or solvent-based coatings. On the one hand, most water-based alkyd products in the market are water-soluble, that is, on the basis of traditional alkyd resins, use trimellitic anhydride or maleic anhydride to control the acid value at 40-60 mgKOH / g, and then add 30-40% glycol ether or Diluted with butanol organic solvents, and finally neutralized with toxic amines, resulting in high resin viscosity, slow drying of the coating film, low hardness, resistance to hydrolysis, and storage stability of the finished paint; on the ot...
