Description

201231570 VI. Description of the Invention: [Technical Field] The present invention relates to an ultraviolet light OJV) curable pigmented aqueous coating composition, and more particularly to an ultraviolet curable pigmented aqueous coating composition for primary application. [Prior Art] In today's information age, various electronic products are widely used in people's lives, such as digital cameras, notebook computers, mobile phones, handheld digital assistants (PDAs), home appliances, etc. The plastic material has the advantages of easy molding, low cost, light weight, and non-corrosion. However, it is inferior to the metal material in terms of aging and mechanical properties, and is also inferior to the performance of the metal material in appearance. Therefore, in order to overcome the above problems, the currently used process is to form a protective and/or decorative coating on the surface of the plastic part by coating baking. In the past, most of the coatings used for substrates were solvent-based coatings. However, volatile organic solvents (VOCs) emitted by solvent-based coatings into the atmosphere had a bad environmental impact. In recent years, due to human attention to environmental protection and energy, countries around the world have strictly controlled the content of V0C in coatings, which has led to the transfer of coating materials from conventional solvent-based coatings to water-based coatings. Compared with solvent-based coatings, water-based coatings have the advantage of not containing VOC or V0C, and have low environmental pollution. Conventional coating on the surface of plastic parts generally requires two-baked or three-baked three-baked procedures. In the case of two-coating and baking, the primer is first applied. The primer serves to provide the desired color on the surface of the substrate and because of its adhesion to the substrate and the 201231570 topcoat, the substrate can be sealed and enhanced. The adhesion of the painted topcoat to the substrate, and the like. After the primer is baked, the top coat is sprayed, and the top coat and the primer are combined to make the overall coating exhibit various colors and luster, and the coating has high hardness, high wear resistance and high chemical resistance. characteristic. Since it has to undergo two operations of two coatings and two baking processes, not only the amount of coating material is large, but also the labor time is very high, thereby increasing the cost. Therefore, the industry is committed to developing coating compositions that achieve a combination of aesthetics and performance through a single coating. For example, Taiwan Patent No. 1290566 discloses a pearl paint ultraviolet light coating composition for one-time spraying, although the pearl paint ultraviolet light coating composition can be obtained on a plastic part by a one-coating one-time construction process. Coating, however, such a composition is limited to the use of translucent pearlescent pigments. If the pearlescent pigment is replaced by a solid pigment that does not have transparency, the light absorption properties of the solid pigment will cause ultraviolet light to be on the surface of the coating. It is absorbed and cannot penetrate the coating. Therefore, during the curing process of the coating, the monomer or oligomer cannot be effectively polymerized, and the problem that the coating film is not dry or semi-dry is easy to occur. It cannot be guaranteed. The main object of the present invention is to provide an ultraviolet curable pigmented aqueous coating composition comprising the following components: (a) an aqueous oligomer containing at least one unsaturated double bond, said aqueous oligomerization The object is selected from the group consisting of aqueous epoxy acrylate oligomers, aqueous polyurethane acrylate oligomers, aqueous polyester acrylate oligomers, aqueous polyacrylate oligomers, aqueous acrylate oligos a group of aqueous thiol acrylate oligomers and mixtures thereof; 201231570 (b) aqueous medium; (c) photoinitiator; (d) aqueous thermoplastic resin, if desired; The component (c) is 3 parts by weight based on 100 parts by weight of the total of the component (a); and the component (d) is 0 to 3 parts by weight based on 100 parts by weight of the total of the component (a); (e) The content is 2 to 50 parts by weight based on the total of (10) parts of the components (4) and (4). The application of the ultraviolet curable pigmented water-based coating composition of the present invention is the same as that of the sub-supplement method, when the spray is applied, the appearance and the highness can be obtained, and the coating film is compared with the conventional second.
