Mixed mortar for stone-like coating and preparation method thereof

Abstract

The invention discloses mixed mortar for a stone-like coating. The mixed mortar is prepared from the following raw materials in parts by weight: 800 to 1,200 parts of colored stone sand, 960 to 1,450 parts of river sand, 20 to 30 parts of silicon ash, 10 to 20 parts of preservative, 4 to 6 parts of thickening agent, 80 to 100 parts of pure acrylic emulsion, 20 to 30 parts of gypsum and 250 to 350 parts of water. By adopting the mixed mortar, the colored stone sand and the river sand are mixed, so that the stone-like coating can achieve higher color fidelity; by adopting the colored stone sand, the color effect can be improved greatly, and meanwhile the situation of fading after a long time can be avoided; meanwhile, the perception fidelity of the stone-like coating can be improved greatly by the river sand; meanwhile, the river sand is prepared from coarse river sand and fine river sand, so that the stone-like coating has greater concave-convex sense, and the using effect of the stone-like coating is improved greatly.

Description

technical field

[0001] The invention relates to the technical field of genuine stone paint, in particular to a mixed mortar for real stone paint 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, never fade and other ...
