Problems solved by technology

UV-curable coatings are one of the commonly used fire-resistant coatings, but with the development of society, people put forward higher requirements for the performance of UV-curable coatings. The flame-retardant properties of UV-curable coatings currently used are not very ideal. And the service life is short, which can no longer meet the requirements of the society and needs to be modified

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a highly flame-retardant ultraviolet light curing coating. Background technique [0002] Fire is one of the hidden dangers of daily life. Due to the use of a large number of decorative materials in furniture, a variety of toxic gases are produced when a fire occurs, threatening personal safety. At present, almost all the surfaces of furniture used in furniture are coated with paint. These The coating can form a thin film under certain conditions to protect, decorate or other liquid or solid materials with special functions, such as insulation, rust prevention, mildew resistance, heat resistance, etc. Among them, the flame retardant coating can be used when it is painted with a certain thickness. Let the object be fireproof for a long time, protect the object from being damaged by the flame, and at the same time make the plate itself not easy to catch fire, thereby reducing the t...
