Description

Technical Field

[0001] The invention relates to the technical field of coatings, and in particular to a high-hardness multi-color coating and a preparation method thereof. Background Art

[0002] With the continuous advancement of colorful imitation stone coating technology, various products with excellent effects have emerged and are widely used in building exterior wall decoration, adding unique charm to the building appearance. Its decorative effect is not inferior to traditional high-end decorative materials such as granite. Under this development trend, colorful imitation stone coatings with flamed and litchi surfaces are particularly eye-catching, but they each have some limitations.

[0003] The colorful imitation stone paint with a flamed surface effect has a high degree of color point integration, which can excellently show the color effect of the stone and bring a unique visual experience to the exterior wall decoration. However, the texture of its color points is relatively flat, resulting in a slightly insufficient touch feel and three-dimensional visual effect, which may be a great pity in occasions that pursue delicate touch and three-dimensional visual effects. On the other hand, the colorful imitation stone paint with a lychee surface effect is highly favored due to its strong color point texture. It can well show the three-dimensional sense and touch feel, adding a unique texture charm to the exterior wall decoration. However, its color point integration is relatively poor, and the overall color effect may look stiff and unnatural. For this reason, a colorful paint with high hardness, high color integration, strong texture, color point effect like stone, clear and ethereal, and natural overall effect is needed to solve the above problems.
