Abstract

The invention discloses a flame-retardant steel surface coating material and a preparation method thereof. The flame-retardant steel surface coating material is prepared from the following components in parts by weight: 35-48 parts of polyacrylamide, 5-9 parts of zinc oxide, 0.05-0.2 part of ammonium polyphosphate, 0.05-0.1 part of dibutyltin maleate, 0.03-0.1 part of diazolidinyl urea, 0.02-0.04 part of silane coupling agents, 0.01-0.2 part of antioxidants and 15-20 parts of 1,2-pentanediol. The invention also provides the preparation method of the flame-retardant steel surface coating material. The flame-retardant steel surface coating material prepared through the method disclosed by the invention not only has good flame-retardant property, but also has good scraping resistant property and antibacterial property. The flame-retardant steel surface coating material prepared through the method disclosed by the invention can be widely applied to the surfaces of a household appliance, an instrument, a meter, air purifying equipment and water purifying equipment.

Description

technical field [0001] The invention belongs to the field of coating materials, in particular to a flame-retardant steel surface coating material and a preparation method thereof. Background technique [0002] Steel surface coating is a coating material used on the surface of steel materials to change the characteristics of the steel surface. The steel surface coating material can play a good role in protecting the steel surface, and by adding color paste materials, it can change the color and play a decorative effect. At the same time, the coating material on the steel surface can improve the surface tension of the steel and play the role of isolating the air, reducing the oxidation rate of the steel surface and increasing the service life of the material. [0003] Chinese patent CN102585574A discloses a method for preparing a UV-curable flame-retardant coating material, mainly by preparing a functional sol, wherein the functional sol is produced by the co-hydrolysis of a ...
