Abstract
The invention relates to water based UV clear primer and a preparation method and application thereof. The clear primer is prepared from, by weight, 70-90 parts of an water based UV emulsion, 0.4-1 part of an antifoaming agent, 0.3-0.8 part of a wetting agent, 1-3 parts of an water based photoinitiator, 0.2-1 part of a thickener and 1-5 parts of a filming aid; the pH value is 7-9; the solid content of the water based UV emulsion is not less than 50%; the water based UV emulsion is an aliphatic urethane acrylate and/or urethane acrylate emulsion; the solid content of the clear primer is 40% orabove. The clear primer has excellent transparency, fullness, high filling property and other excellent paint film performance after film formation, makes up for the disadvantages that the paint filmof the water based paint is dry and thin and the construction frequency is high, and the pollution resistance, chemical resistance and liquid resistance of the paint film are excellent; direct construction is carried out, or water is taken as a diluting agent, and the clear primer can be applied to roller painting, spraying and other construction modes, and can be applied to coating in the fieldsof panel furniture, solid wood furniture, floors and the like.
Description
technical field [0001] The invention relates to a water-based UV high-volume and high-transparency primer and a preparation method and application thereof, belonging to the technical field of coatings. Background technique [0002] At present, there are mainly two kinds of clear primers for wood coating, oily UV clear primers and water-based clear primers. Due to the high viscosity of oligomers in traditional oil-based UV coatings, diluents must be added to adjust the rheology and viscosity to improve the performance of the coating film. The added diluents include reactive diluent monomers or cross-linking agents, which have a strong irritating effect on the eyes, and skin contact can easily lead to allergies and affect the health of the operator. Residual monomers have side effects such as plasticization and are permeable, directly affecting the long-term performance of the cured film. [0003] Water-based clear primers include one-component, two-component and water-based...
