Abstract

The invention provides a weather-proof reflective paint used for labels, and a preparation method thereof. The weather-proof reflective paint used for labels is prepared from a light reflective powder, acrylic acid emulsion, ethylene-vinyl acetate copolymer emulsion, sodium tripolyphosphate, calcium nitrate, ethyl orthosilicate, sodium hexametaphosphate, modified zeolite, modified glass microbead,rosin resin, guar gum, ethanol, an antifoaming agent, polyurethane thickening agent, and water. The weather-proof reflective paint is green, is friendly to the environment, possesses excellent adhesive force on substrate, excellent flexibility and weatherability, is better than conventional paint, and is wide in application range; and no pollution is caused.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a weather-resistant reflective coating for signs and a preparation method thereof. Background technique [0002] With the development of the coatings industry, various functional coatings have emerged, and reflective coatings are one of them. Reflective coatings are bright in color and high in brightness, and are widely used in outdoor decoration and emergency indication signs. However, due to the humidity and precipitation outdoors, the existing reflective coatings generally do not have waterproof effect, resulting in poor stability of reflective coatings, easy to fall off, and long service life. short. [0003] The main raw materials used in reflective coatings include resins, pigments, glass beads, etc., and any raw material is crucial to the performance of reflective products. Among them, the bonding resin must have good construction performance and excellent b...
