[0095] According to a second aspect of the present invention, the present invention provides the preparation method of the above-mentioned sand-in-sand colorful coating, comprising the steps of:
[0096] (c) adding the base material containing sandy colored grains into the granulation liquid, and granulating to obtain sandy colored grains;
[0097] (d) Add the sand-containing colored particles into the real stone paint and mix evenly to obtain a sand-in-sand colorful paint.
[0098] The preparation method of the sand-in-sand multi-color paint provided by the invention has simple process and convenient operation, is applicable to large-scale production, improves production efficiency and reduces production cost.
[0099] In a preferred version of the present invention, in step (a), water-based iron oxide series colorants are used to color the base material containing sand-colored particles and then added to the granulation liquid, so that the prepared sand-containing color The...
Embodiment 1
[0116] This embodiment provides a sand-in-sand multi-color paint, which is prepared from sand-containing colored particle base material, granulation liquid and real stone paint. The mass ratio of the three is 10:5:85, wherein the sand-containing colored particle base Materials include the following raw materials in parts by mass:
[0117]
[0118] The above-mentioned 7% protective glue refers to an organically modified nano-lithium magnesium silicate solution in which the mass ratio of the organically modified nano-lithium magnesium silicate is 7%, and the balance is water.
[0119] The granulation liquid includes the following raw materials in parts by mass:
[0120]
[0121] Real stone paint includes the following raw materials in parts by mass:
[0122]
Embodiment 2
[0124] Embodiment 2 provides a sand-in-sand multi-color paint, which is prepared from sand-containing colored particle base material, granulation liquid and real stone paint, and the mass ratio of the three is 40:20:40, wherein the sand-containing colored particle base The raw material composition of material, granulation liquid and genuine stone paint is all identical with embodiment 1, repeats them no longer here.

Abstract
The invention provides a sand-in-sand multi-color coating and its preparation method and application, and relates to the technical field of coatings. The sand-in-sand multi-color coating includes sand-containing color grain base material, granulation liquid and real stone paint. The mass ratio of the three is Be (10-40): (5-20): (40-85), wherein, comprise the colorful base material emulsion that contains diacetone acrylamide in the described sand color particle base material, include acyl acrylamide in the described granulation liquid Hydrazine compounds, the real stone paint includes diacetone acrylamide containing real stone paint emulsion. In the sand-in-sand multi-color paint provided by the invention, the ketone carbonyl group introduced by the multi-color base material emulsion containing diacetone acrylamide in the sand-containing color particle base material is cross-linked with the hydrazide compound in the granulation liquid, and granulated at the same time The hydrazide compound in the solution cross-links with the ketone carbonyl group introduced by the real stone paint emulsion containing diacetone amide, and forms a three-dimensional network structure, thereby significantly enhancing the film strength of the sand-in-sand colorful paint.
Description
technical field [0001] The invention relates to the technical field of coatings, in particular to a sand-in-sand multi-color coating and its preparation method and application. Background technique [0002] Nowadays, with the improvement of living standards, people's architectural decoration is not limited to simple imitation stone pattern decoration, but also requires realistic stone texture effect and high-strength performance. However, the current colorful imitation stone coatings have the following problems: water-in-water multi-color coatings can only imitate the pattern of stone, and to achieve a concave-convex effect, it is necessary to add a real stone paint / texture coating, and water-in-sand multi-color coatings are not enough to imitate the strong concave-convex feeling of stone Obviously, the existing sand-in-sand coating is physically bonded between the color particles and the continuous phase, causing it to become soft and whitish after being soaked in water, an...
