Description
Technical Field
The invention relates to the technical field of powder coatings, in particular to a powder coating with a moire effect and a preparation method thereof.
Background
Powder coatings represent a rapidly growing area in the overall coating technology. Because the VOC emission is almost zero, the rapid development of the VOC is driven by the environmental protection requirement. The requirements of global and Chinese environmental protection laws and regulations are more and more strict, and the development of the environmental protection powder coating industry is effectively promoted.
The powder coating with the moire effect is a coating type similar to the appearance of a tortoise shell as the name suggests, and has strong touch and visual sense. The tortoise-pattern decorative paint is a new product developed in the early nineties of Japan. The early developed coating is acrylic acid series water-based emulsion paint, which consists of bottom, middle and top three layers of coatings. The main two base materials are copolymerized by using a unique cross-linking agent, and the coating film is fine and smooth, tough and strong in adhesive force. After the paint prepared by the two base materials is constructed on the wall surface, double-color and regular pattern can be naturally formed, the stereoscopic impression is strong, and the color is various. The paint can also be applied to the surfaces of wood, metal, plastic and the like. The coating is suitable for decoration of inner walls and suspended ceilings of buildings such as hotels, shopping malls, villas, entertainment places, modern office buildings, family rooms and the like, and is a medium-high grade inner wall decorative coating which has better social benefits and is worth popularizing and applying.
As people no longer satisfy the decoration of monotonous gloss or color change for various home appliances, equipment and the like to be coated, the art type powder coating obtains the decoration effect which is difficult to achieve by the common decorative powder coating because the surface of a coating film has beautiful and clear patterns.
Therefore, there is a need for a powder coating with moire effect and a method for preparing the same based on the prior art to solve the above problems.
