Description
Technical Field
The invention relates to a coating, and in particular relates to a high-shading black laser etching non-discoloring coating and a preparation method thereof.
Background
In the field of coatings used for automobile interior function buttons, computer keyboard buttons, buttons with indication functions of various devices and the like, most of the coatings adopt a process of spraying black paint and then laser engraving to expose indication characters or patterns. The existing black laser etching paint on the market has a common fault, the color of the character graph line after laser etching obviously changes, the character graph line is not the color of the substrate, and the character graph line is probably more yellow, more blue or more red than the substrate, and the batch is also very unstable. The appearance design of the product is influenced, the color matching and the aesthetic feeling of the product are influenced, the standardized production of the product is obviously influenced, and the impression of the product quality in the heart of a client is reduced. The reason is that the black laser etching coating used by the products meets the requirement of standard colors by adding red, yellow, blue, green and other color pastes when researching, developing and producing and adjusting red-green (a value) and yellow-blue (b value) color phases of the products, and the color pastes are unknown, are burnt by high energy of laser when the products receive laser etching, and generate oxidation reaction, so that the appearance color is changed, and color migration along the downward direction of laser etching is generated and attached to a substrate, so that the color of the character pattern edge engraved by the laser is obviously different from the color of the original substrate, and the degree of color change is influenced by the film thickness, the laser etching energy, the proportion of the color pastes and the like, and obvious difference exists among batches.
The invention aims to solve the industrial problem of laser etching color change caused by adding color paste to the laser etching black coating due to color adjustment.

The invention firstly develops and manufactures three types of color black paste: pretreated blue-green black color paste, pretreated yellow black color paste and pretreated red black color paste. The blue-green phase black paste is pretreated to obtain a unique blue phase by using a micro-blue transparent system formed by mixing resin and a dispersant in a micro-incompatible manner, and a dispersion multiplying agent is matched, so that the blue-green phase (b value) is greatly improved under the condition that the blackness of a prepared paint coating film is not lost, and the black paste with a blue-green phase is prepared; the pretreated yellow-phase black paste and the pretreated red-phase black paste are both prepared by screening the most suitable dispersing agent and black powder to realize the yellow-phase black paste and the red-phase black paste. The black pastes with three hues are matched with each other for use, so that different hue requirements can be realized, different hue standards or production toning requirements can be met, and the use of color pastes is avoided. The pigment in the paint is only black powder, namely carbon black in a scientific name, the carbon black is a product obtained by insufficient combustion or thermal decomposition of an organic matter, the performance is stable, no further reaction is usually carried out when the paint is heated, even if high-energy laser is encountered, partial reaction only can generate carbon monoxide or carbon dioxide gas to volatilize out, and substances with other colors cannot be generated, so that the problem of color change of characters and graphs after laser engraving is avoided.
In the coating, the color matching requirement is met by originally researching and manufacturing three types of black slurry with different colors, the use of color paste is avoided, and the problem of laser etching color change existing in the industry all the time is solved.
