Abstract

The invention belongs to the field of coatings, and particularly relates to an environment-friendly aqueous UV coating and a preparation method thereof. The environment-friendly aqueous UV coating isprepared from the following raw materials in parts by weight: 40 to 90 parts of UV-cured aqueous polyurethane dispersion, 10 to 60 parts of acrylate emulsion, 0.1 to 3 parts of a photoinitiator, 0 to2 parts of a silane coupling agent, 0.1 to 1 part of a surfactant, 0.5 to 12 parts of an auxiliary agent, 0 to 4 parts of a light stabilizer and 0 to 50 parts of water. The environment-friendly aqueous UV coating has high weather resistance and adhesiveness, meanwhile, the viscosity is adjusted with water, the viscosity does not need to be adjusted with the help of an active diluent, the problemsof VOC, toxicity and irritation can be solved, the coating can be used immediately after being opened, a curing agent does not need to be added, and meanwhile the coating can be recycled.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an environment-friendly water-based UV coating and a preparation method thereof. Background technique [0002] With the enhancement of human awareness of environmental protection, countries have successively formulated environmental protection regulations on VOC emissions, and the emission standards have become increasingly strict, aiming to promote new products that are green, environmentally friendly, energy-saving and emission-reducing. Therefore, in the field of paint coating, the development and application of safe and pollution-free paint is imperative. [0003] UV coatings are also called Ultra-Violet Ray curing coatings, which are mainly irradiated by ultraviolet lamps to cure the coatings to form films. The industrial ultraviolet wavelength is 200nm-450nm as its application range. UV coatings can be applied by roller coating and curtain coating. , spraying and other ...
