Abstract

The invention provides a colorful graphene quantum dot coating and a preparation method and application thereof, and relates to the technical field of coatings. The colorful graphene quantum dot coating is mainly prepared from the following raw materials in parts by mass: 5-40 parts of graphene quantum dots, 3-10 parts of pigment, 90-120 parts of matrix resin, 330-370 parts of deionized water and 450-550 parts of filler; and the sum of the raw materials is 1,000 parts. The technical problem that an existing coating is single in color, is lack of colorfulness, and easily causes visual aesthetic fatigue of people is solved. The antibacterial performance is good, colors with a wide chromatography range can be shown, therefore, visual aesthetic fatigue of people is relieved effectively, and demands of people to diversity of colors of coatings are met.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a colorful graphene quantum dot coating and its preparation method and application. Background technique [0002] At present, all kinds of existing paints, whether they are water-based paints or solvent-based paints, as well as powder paints, high-solid paints, etc., all have one variety and one color, and the color of the paint can only be adjusted according to the existing pigments, so that the color tone of the paint Single, lack of colorfulness, easy to make people visual fatigue. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] One of the objectives of the present invention is to provide a colorful graphene quantum dot paint, to relieve the existing paint that only has one color in one variety, and the color of the paint can only be adjusted according to the existing pigment, so that the color tone of the paint is single and...
