Environment-friendly ultraviolet color-changing color paste, and preparation method and application thereof

Abstract

The invention discloses environment-friendly ultraviolet color-changing color paste, and a preparation method and application thereof. The color paste comprises the following raw materials in parts byweight: 55-68 parts of ultraviolet color-changing powder, 30-38 parts of polyvinyl chloride (PVC) paste resin, 8-16 parts of diatomaceous earth, 15-30 parts of an environment-friendly plasticizer, 16-23 parts of PVC resin powder, 15-22 parts of white oil, 26-43 parts of deionized water, 11-19 parts of light calcium carbonate, 2-3 parts of an ultraviolet absorbent and 7-12 parts of nano silicon dioxide. According to the invention, through double grinding, the particle size of the color-changing color paste is reduced, the specific surface area is increased, and the coloring force is higher. The color-changing color paste has small fineness, high glossiness, excellent dispersing effect and excellent storage stability. The environment-friendly plasticizer is adopted to synthesize plant ester, so that when being dissolved in an injection molding medium of plastic sandals and foam sandals, the color-changing color paste has excellent bonding performance with the plastic sandals. In addition, the color-changing color paste is free of aromatic compounds, has good safety, is capable of achieving automatic color changing function under ultraviolet irradiation through ultraviolet color-changing powder, and thus has a wide application prospect.

Description

technical field [0001] The invention relates to an environment-friendly ultraviolet color-changing color paste, a preparation method and application, and belongs to the technical field of color-changing color paste. Background technique [0002] The color paste is a mixed paste obtained by adding fillers and some additives to the pigment. The color paste is dispersed in the paint to form a colored paint. According to the different solvents used in the color paste, the color paste is divided into water-based Color paste, oil-based color paste, water-oil general color paste, etc.; according to the different uses of color paste, it is divided into paint color paste, tape color paste, papermaking color paste, textile color paste, mechanical color paste, toy color paste, latex product color paste Color paste, etc.; According to the different tools for using color paste, people simply divide color paste into factory color paste and machine color paste, etc. [0003] With the diff...

[0005] In the prior art, the Chinese patent with the patent application number CN 201621379032.8 discloses "an ultraviolet invisible color-changing shoe, including a shoe upper and a sole, the shoe upper is fixedly connected to the top of the shoe sole, the shoe upper includes a shoe upper inner layer, and the shoe upper The outer surface of the inner layer is fixedly connected with the surface of the corium layer, the surface of the corium layer away from the inner layer of the upper is fixedly connected with invisible materials, the upper surface of the sole is in contact with the lower surface of the insole, and the lower surface of the insole is in contact with The top of the support block is fixedly connected, the bottom of the support block is inserted into the empty slot and extends to the inside of the empty slot, and the empty slot is opened on the sole; the ultraviolet invisible color-changing shoes, through the setting of invisible materials, make the shoes stand in the sunlight Patterns can appear under the light, which solves the problem that the existing shoes are too monotonous, so that the shoes can change the pattern according to the change of sunlight, so that the shoes are more individual and fashionable, and the shoes can be more suitable for young, fashionable, individual and trendy people. Consumers", but there are still defects, the invisible material has poor bonding ability with shoes, easy to fall off, and poor stability
