Abstract

The invention belongs to the field of coatings, and in particular relates to a UV-cured flame-retardant coating. The coating includes the following components according to mass percentages: 30 to 50 percent of a compound which can produce acids in situ when burned, 5 to 15 percent of an organic compound with a plurality of hydroxyls, 20 to 40 percent of UV photo-cured resin, 20 to 35 percent of a reactive diluent, and 1 to 3 percent of a photoinitiator. The invention aims to provide the UV-cured flame-retardant coating to overcome defects in the prior art; the UV-cured flame-retardant coating has remarkable flame-retardant performance, and undergoes foam expansion to form a honeycomb fireproof and heat-insulating layer when burned, so as to effectively protect materials and achieve remarkable flame-retardant effect; the traditional flame-retardant system in which melamine is used as a nitrogen source is abandoned, and the prepared highly-transparent UV-cured flame-retardant coating is applicable to wood floors, fiberboards, plywood, and cement boards for interior and exterior walls, so that the application range is enlarged.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a UV curing flame retardant coating. Background technique [0002] Fire is one of the major hazards to human beings. In order to prevent the occurrence of fire accidents, it is an effective measure to apply fire retardant coatings to buildings and combustible materials. Fire retardant coatings, also known as flame retardant coatings, not only have decorative functions, but also have the function of fire retardant and flame retardant. [0003] The commonly used fire retardant coatings are mostly water-based or oil-based fire retardant coatings, but there are some common problems. Ordinary fire retardant coatings generally need to be applied 2-3 times, with an interval of 6-8 hours, and it takes several days to dry; during the drying process, volatile organic compounds will endanger people's health; there is adhesion to different substrates Not good enough, low hardness, etc. ...
