Environment-friendly stone-like coating and preparation method thereof

The invention relates to environment-friendly stone-like coating and a preparation method thereof. The environment-friendly stone-like coating is prepared from the following components in parts by weight: 20 to 40 parts of silicone acrylic emulsion, 80 to 150 parts of natural quartz sand, 10 to 15 parts of glass fibers, 0.5 to 1 part of a thickening agent, 0.2 to 1.5 parts of a dispersing agent, 5to 7 parts of a coalescing agent, 0.5 to 1.5 parts of a defoaming agent and 30 to 50 parts of water. According to the invention, the glass fibers are added into the stone-like coating, and the sterichindrance effect of the glass fibers is utilized, so that the stone-like coating has better storage stability during storage. The compactness of the stone-like coating can be enhanced, so that the weather resistance, the water resistance, the stain resistance, the impact resistance and the cracking resistance of the stone-like coating are improved. The glass fibers are cheap, so that the stone-like coating has certain eco
