Problems solved by technology

[0003] Water-based alkyd resin has the characteristics of using water as a solvent, easy to obtain raw materials, low price, and excellent comprehensive performance of paint film. It is an ideal resin for preparing environmentally friendly long-lasting luminescent coatings; In addition, the luminescent powder is easily hydrolyzed with water and loses its luminous function.
Therefore, there is no literature report on the use of water-based alkyd resin as a film-forming substance for long-lasting luminescent coatings.

Embodiment Construction

[0028] The preparation method of the long-lasting water-based alkyd resin coating of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The preparation method operating steps of the long afterglow water-based alkyd resin coating of the present invention are as follows:

[0030] (1) Preparation of water-based alkyd resin

[0031] The first step, material preparation: put soybean oil oleic acid, tung oil, glycerin, and trimethylolpropane into a four-necked flask containing a stirrer, a thermometer, an oil-water separator, and a nitrogen pipe according to the designed formula ratio, and feed nitrogen into the flask. Under stirring, heat up to 120°C;

[0032] The second step, alcoholysis: add lithium hydroxide, continue to heat up to 230 ° C, keep warm for 1.5 hours, and then detect the degree of alcoholysis every 20 minutes, the detection method is according to the test substance in the...

Abstract

The invention discloses a preparation method of a long-lasting water-based alkyd resin paint, which introduces a long-lasting luminous powder into a water-based alkyd resin system, and first uses soybean oil, tung oil, glycerin and other biomass oils to undergo alcoholysis with lithium hydroxide. , through xylene, phthalic anhydride, maleic anhydride esterification, and then through neutralization and dilution to obtain water-based alkyd resin, and then fully react with titanium dioxide, talc powder and long-lasting luminous powder mixture, through three Adjust pH=8.0-8.5 with ethylamine and keep warm to obtain an environment-friendly long-lasting water-based alkyd resin coating with fluorescent properties. The long-lasting luminous coating product prepared by the method for preparing the long-lasting water-based alkyd resin coating has the advantages of good water resistance and dryness, low production cost, excellent product performance and environmental protection.
