CN-122011824-A - Black coloring material based on natural photosensitive substance self-enhancement and preparation method thereof

Abstract

The invention discloses a black coloring material based on natural photosensitive substance self-enhancement, belonging to the technical field of fine chemical engineering and coloring materials. The material is prepared by compounding base resin serving as a base material with black coloring agent, natural photosensitive active components, functional additives and a solvent, wherein the natural photosensitive active components undergo oxidative polymerization and deep color development under the action of illumination and oxygen, so that the system is continuously deepened and continuously improved in gloss, a compact crosslinked structure is formed, and the coloring effect and the protective performance are self-enhanced along with time. The invention is not limited by application forms, can be widely used in the whole fields of paint, pigment, coating, colorant, chemical industry, automobile, machinery, daily products and the like, and has strong stability, environmental protection and extremely high commercial value.

Description

Black coloring material based on natural photosensitive substance self-enhancement and preparation method thereof Technical Field The invention belongs to the technical field of fine chemical engineering, in particular to the technical field of black coloring materials, and particularly relates to a black coloring material which is self-reinforced based on oxidation of a natural photosensitive substance and can realize that the longer the color is, the darker the brighter the color is, and a preparation method thereof, and the black coloring material can be widely applied to various coloring and protection scenes such as paint, pigment, coating, printing ink, chemical industry, automobiles, machinery, hardware, plastics, woodware, buildings, equipment and the like. Background The black coloring material is a core base material in industries of fine chemical engineering, pigment, paint, coating, plastic products, hardware, automobiles, daily products and the like. The existing black coloring system has the problems of easy fading, whitening, light loss, aging, performance attenuation and the like, the active improvement of color and protective performance cannot be realized, part of chemically modified materials have poor environmental protection, the natural photosensitive color development system does not form a standardized black coloring product which can be applied in large scale, and huge technology and market blank exist. Disclosure of Invention The invention aims to provide a black coloring material based on natural photosensitive substance self-enhancement, which breaks through the traditional black industry pain points which are easy to fade and easy to lose light by utilizing the characteristics of natural substances such as automatic oxidation, deep color development and continuous blackening and brightening in a photo-oxygen environment, realizes double self-enhancement of coloring effect and protective performance, can be compatible with various product forms such as paint, pigment, coating, colorant and the like, and is suitable for large-scale industrial application in the whole field. The technical scheme is that the black coloring material based on natural photosensitive substance self-enhancement comprises the following components in parts by weight: 30-60 parts of base resin, namely one or more of epoxy resin, polyurethane resin, acrylic resin and fluorocarbon resin; 5-15 parts of black coloring components and carbon black coloring agents; 2-8 parts of natural photosensitive active components which are one or a combination of more of polyphenols, tannins, flavonoids, anthraquinones, alkaloids, lignin, melanin precursors and plant extract photosensitive color development components; 1-5 parts of functional auxiliary agent, dispersing agent, leveling agent, antirust agent and curing agent; 10-30 parts of solvent, namely one or more of ethyl acetate, dimethylbenzene and deionized water. FIG. 1 is a schematic diagram of the composition of coloring material The drawings only express the structural relation of the components and do not represent the actual weight proportion, and are used for explaining the composition system of the black coloring material of the present invention. The preparation method comprises 1. Stirring base resin and solvent to form base solution; 2. adding black coloring components and dispersing agents, dispersing at high speed, and grinding; 3. Adding natural photosensitive active components, flatting agents and rust inhibitors, and uniformly mixing; 4. Adding a curing agent, stirring and filtering to obtain the self-reinforced black coloring material. FIG. 2 is a flow chart of the preparation process The diagram is a complete preparation flow, and is suitable for industrialized mass production. The beneficial effects are that: 1. Natural photosensitive self-blackening and brightening, namely automatic oxidation and color development under the conditions of illumination and oxygen, wherein the longer the black is, the thicker the black is, the longer the luster is, and the higher the luster is, so that the problems of fading, whitening and light loss are thoroughly solved. 2. The performance self-enhancement is that the crosslinking density of the system is continuously improved, and the weather resistance, salt fog resistance, corrosion resistance and adhesive force are continuously improved. 3. The coating is not limited to paint, and can be used as pigment, colorant, coating, colorant, ink and dyeing material. 4.
