Problems solved by technology

However, in the actual application of most real stone paints at present, there are often some problems affecting the construction quality of the coating and the decorative effect in the later period, especially in the north and south of my country. During construction, it often occurs that the coating will become white when it encounters water in the early stage after construction, that is, the initial water resistance after coating construction is poor; Erosion of pollutants, real stone paint is polluted and affects the appearance and decorative effect of the coating, that is, poor stain resistance

Abstract

The invention relates to real-stone paint and a preparation method thereof and belongs to the technical field of building decorative materials. Firstly, an inorganic mineral rheological agent and a nonionic water-soluble cellulose ether are combined, so that the two components have the synergistic effect of guaranteeing viscosity of the real-stone paint and excellent constructability, and on the basis hereinabove, the usage amount of cellulose ether, which has water retention effect, in the real-stone paint is reduced, so that a paint film is reduced in the water retention effect and moisture volatilization is improved; secondly, alcohol ester-12 is combined with any one of four film forming additives, comprising ethylene glycol monobutyl ether, propylene glycol butyl ether, diethylene glycol butyl ether and benzyl alcohol, which have high volatile speed, thus accelerating film forming. For solving of a problem of poor antifouling performance of the real-stone paint, through reasonable combination of particle size of color sands and usage of a hydrophobic agent, the real-stone paint can form a compact film and a nano hydrophobic coating layer, which is completely composed of nano hydrophobic particles, is formed on the surface of the paint film, so that the paint film is reduced in surface energy and water absorbency, and is improved in antifouling performance.

Description

technical field [0001] The invention relates to a real stone paint and a preparation method thereof, belonging to the technical field of building decoration materials, in particular to a real stone paint with good initial water resistance and stain resistance and a preparation method thereof. Background technique [0002] Real stone paint is made of acrylic emulsion as the main film-forming substance, stone crushed stones of various colors and particle sizes as aggregate, and various additives are used to form a building with a stone decorative effect on the surface of the building. coating. Because of its low resource consumption, easy construction, no safety hazards, rich colors and varieties, it is more and more widely used in construction. However, in the actual application of most real stone paints at present, there are often some problems affecting the construction quality of the coating and the decorative effect in the later period, especially in the north and south ...
