Embodiment 1
[0020] In Example 1, waste tire rubber particles are directly used as black imitation stone particles.
Embodiment 2
[0021] The processing methods of Examples 2 and 3 are as follows: firstly, the plastic paint and the dispersant are mixed evenly, then pearlescent pigments, gold powder or silver powder are added, and the mixture is evenly stirred. Then, centrifuge to remove excess plastic paint. After drying to form a film, the imitation stone particles of the desired color can be obtained. Embodiment 2 obtains light imitation stone particles with a small amount of pearl luster. Embodiment 3 obtains light imitation stone particles with a small amount of silver and gold.
[0022] The processing method of embodiment 4 and 5 is, select the plastic paint of certain color according to required color, then mix solidified epoxy resin or carbonate waste granule with plastic paint, stir, centrifuge and remove excessive plastic paint. After drying to form a film, the imitation stone particles of the desired color can be obtained.

Abstract
The invention provides a light stone-imitating particulate matter and a water-based stone-imitating coating prepared by adopting same, and belongs to the technical field of water-based architectural coatings. The preparation method comprises the following steps: smashing or cutting waste or a leftover material of rubber, resin and engineering plastics or reclaimed rubber into particles, coating a colored film on the surface to prepare the light stone-imitating particulate matter. The water-based stone-imitating coating prepared by adopting the stone-imitating particulate matter comprises the following ingredients in percentage by weight: 8-30% of emulsion, 30-80% of a light stone-imitating particulate matter, 1-40% of an inorganic pigment filler, 1-8% of a wetting dispersant, 0.5-8% of a thickening agent, 0.1-5% of an antifoaming agent, 0.5-5% of a film coalescing aid, 0.1-1% of a mildew inhibitor, 1-10% of an anti-freezing agent, and proper amount of water, wherein the pH value is regulated to be 8-9.5 with a pH regulator. The imitated stone is life-like, and presents strong artistic feeling. As the specific weight of the light stone-imitating particulate matter is low, the flexibility is good, and the abrasiveness to a mixing plant is low; a lot of thickening agents or anti-setting agents are not required to be added, and the prepared stone-imitating coating has high stability, long storage life, and convenience in construction. Moreover, the technology avoids black pollution such as waste tires, and is beneficial to environment protection.
Description
technical field [0001] The invention relates to a building material, in particular to a stone-like particle and a water-based stone-like paint prepared therefrom, belonging to the technical field of water-based architectural paint. Background technique [0002] Imitation stone coating is a hot spot in architectural coating at present, and the research and development and market of related products are very active. There are three main types of imitation stone paints that are currently on the market or found in patent documents: the first type is the so-called real stone paint that adds natural colored sand, the second type is the imitation stone paint that adds artificial color blocks or rock flakes, and the third type is the use of water-based paint. Preparation of gel blocks of different colors from emulsion (a high-solid water-in-water-in-water multi-color granite coating and its preparation method, 201110188800.7; environmentally friendly water-based imitation stone coat...
