Abstract

The invention provides a dual-curing coating. The coating comprises a light-cured resin prepolymer, a heat-set resin prepolymer, an active diluted monomer and an initiator, wherein the light-cured resin prepolymer is a multi-functional-group modified acrylic resin prepolymer, and the molecular structure of the multi-functional-group modified acrylic resin prepolymer comprises multiple ethyoxyl groups and / or epsilon-caprolactone groups. The two kinds of modified groups can obviously improve the flexibility of the multi-functional-group modified acrylic resin prepolymer, so that the stretching performance of the coating is improved, and coating has the high extensibility and elasticity after film forming. Meanwhile, the heat-set resin prepolymer is introduced, the phenomenon that a film is thermally expanded in the high temperature state or deforms under the effect of external force can be further avoided, the film appearance character changes under the high temperature condition and the external force are prevented, and the phenomenon that the coating is fractured and peeled under the high temperature after film forming is avoided. Meanwhile, due to addition of the heat-set resin prepolymer, the coating film can have the high hardness and abrasion performance.

Description

technical field [0001] The invention relates to the technical field of UV curing coatings, in particular to a dual-curing coating. Background technique [0002] Traditional UV curable coatings can meet the requirements of abrasion resistance, high temperature resistance, high rigidity and high tensile strength in actual use. However, for emerging furniture decoration products or furniture products (such as furniture with curved surfaces, or decorative products with certain radians, chamfers, and concave corners), traditional light-curing coatings have lost their advantages. Because the UV-curable coating required for this type of product not only requires abrasion resistance, high temperature resistance, high rigidity and high tensile strength, but also needs to have high elongation and high elastic modulus. These requirements are difficult to meet with traditional UV curing coatings. The main performance is that the traditional UV curing coating is prone to breakage or be...
