Abstract

The invention relates to a UV-light solidifying paint having decorative effect and preparation method thereof, in particular to a light solidifying paint containing mica coated with metallic oxides as a paint. The paint is composed of the followings in proportions: the content of low polymer is 30-70wt%; the content of reactive diluent is 25-65wt%; the content of light trigger is 0.5-10wt%; the content of pearlescent pigment is 3-30wt%; the content of accessory ingredient is 0.2-8wt%; the content of solvent is 0-50wt%. As added pearlescent pigment has strong metallic performance, the prepared light solidifying paint has the character of strong pearl effect and also has very good water resisting property, higher rigidity and abrasive resistance. The paint can be applied to decoration on the surfaces of motor vehicles, electric appliance, furniture, articles for daily use, toys, walls, leather products, etc.

Description

Technical field [0001] The invention relates to an ultraviolet light curing paint with decorative effect and a preparation method thereof. It is characterized in that the light curing paint is prepared by using pearlescent pigments and has the characteristics of strong metallic texture, high hardness, wear resistance and the like. Background technique [0002] Pearlescent pigments are based on the principles of physical optics to produce elegant luster and colors similar to those of natural pearls, shells, butterflies, birds and metals. They are a class of pigments classified according to their functions. It consists of a natural mica sheet with a flat surface and a low optical refractive index as the core, and is covered with transparent high refractive index titanium dioxide or iron oxide to form a sandwich wafer. It relies on the refraction and transmission of light to create hue and luster, thereby making it It creates a deep layering and special pearl luster effect in a tran...
