Problems solved by technology

[0003] However, at present, in the actual construction of real stone paint for exterior walls of construction projects, due to the influence of various uncertain factors and changes in the external environment, there are many problems in the application of real stone paint for exterior walls, such as: blooming phenomenon will occur after soaking in rainwater, Major quality problems such as large color difference, yellowing when exposed to water, and shedding of bulges. The existence of these problems not only affects the actual decorative effect of real stone paint, but also affects the quality of the entire project and the use effect of buildings.

Abstract

The invention relates to the technical field of building decoration materials, in particular to a waterproof stone-like coating. The stone-like coating is prepared from the following ingredients in parts by weight: 15 to 35 parts of waterborne epoxy resin, 3 to 15 parts of a waterborne curing agent, 5 to 18 parts of graphene, 80 to 120 parts of aggregates, 15 to 20 parts of organic modified bentonite, 10 to 25 parts of hydroxyethyl cellulose, 0.5 to 2 parts of modified siloxane, 0.5 to 1.5 parts of a wetting dispersant, 1 to 4 parts of a coalescing agent, 0.5 to 0.8 part of a defoaming agent, 0.5 to 1.2 parts of a thickening agent, 0.5 to 1.5 parts of a mildew preventive, 0.5 to 3 parts of a pH regulator and a proper amount of water, wherein the aggregate is composed of natural colored sand and quartz sand according to a weight ratio of (1-3): (1-2), the particle size of the natural colored sand is 40-80 meshes, and the particle size of the quartz sand is 80-120 meshes. The invention also provides a preparation method of the waterproof stone-like coating. The waterproof stone-like coating is greatly enhanced in water resistance, weather resistance and stain resistance, so the development and application of the stone-like coating are promoted.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to waterproof genuine stone paint and a preparation method thereof. Background technique [0002] Real stone paint has rich colors and strong colorability, which can create a harmonious and elegant architectural atmosphere. It has strong adhesion, fire resistance and corrosion resistance. Compared with traditional architectural coatings, it has wider environmental adaptability, making it widely used. For use on exterior walls. As one of the fastest-growing exterior wall paints in the current market demand, real stone paint is more and more favored by the market. [0003] However, at present, in the actual construction of real stone paint for exterior walls of construction projects, due to the influence of various uncertain factors and changes in the external environment, there are many problems in the application of real stone paint for exterior walls, such as...
