A kind of temperature-resistant real stone paint and preparation method thereof

Abstract

The invention relates to the technical field of stone-like coatings, in particular to a stone-like coating resisting temperature variation construction and a preparation method thereof. The stone-like coating is prepared from, by weight, 1-3 parts of hydroxyethyl cellulose, 0.1-2 parts of a rheological agent, 0.1-2 parts of a pH regulator, 5-9 parts of an antifreezing agent, 3-9 parts of a coalescing agent, 90-120 parts of emulsion, 0-3 parts of a preservative, 600-900 parts of natural colored sand in reasonable granular composition and a proper amount of water. By reasonably controlling the fineness and use amount of the natural colored sand and introducing the rheological agent, flowing of the fine sand is greatly hindered, the construction temperature range is widened while good texture is maintained, the problem that the color of the colored sand varies at different temperatures is solved, all-day construction of the stone-like coating can be achieved, and thus working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of real stone varnish, in particular to a real stone varnish for temperature-resistant construction and a preparation method thereof. Background technique [0002] Real stone paint is a kind of paint with a decorative effect similar to marble and granite. It is mainly made of natural stone powder of various colors, and it is applied to the imitation stone effect of building exterior walls, so it is also called liquid stone. The buildings decorated with real stone paint have natural and real natural color, which gives people elegant, harmonious and solemn aesthetic feeling. It is suitable for indoor and outdoor decoration of all kinds of buildings. Especially when it is decorated on curved buildings, it is vivid and lifelike, and has an effect of returning to nature. Real stone paint has fire protection, waterproof, acid and alkali resistance, and pollution resistance. Non-toxic, tasteless, strong adhesion...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, one of the main problems in the use of real stone paint is the color difference. The real stone paint containing more than two kinds of different sands will appear uneven spots on the surface of the coating film after application. The root cause is this. Due to the different fluidity of different sands, finer sands are more fluid and easy to float on the surface to form the base color, and under the influence of temperature, the fluidity of sand will also be greatly different, construction at different temperatures, The color difference of real stone paint can be greater than 2 grades

Therefore, the current construction time is generally limited to the morning and evening when the temperature is low, while the construction is stopped during the daytime when the visibility is high but the temperature is high, which not only greatly prolongs the construction time, but also increases the difficulty of construction.
