Problems solved by technology

[0003] General hydrophobic materials use non-polar surface materials so that water molecules cannot be firmly attached to the surface of the material; use protrusions and burr structures to reduce the contact area between water and the film; use non-polar materials to increase the film thickness as much as possible , to reduce the influence of charges between the subst

Abstract

The invention discloses a multi-composite modified hydrophobic stone-like coating and a preparation method thereof. The feed multi-composite modified hydrophobic stone-like coating is prepared from the following raw materials in parts by weight: 100-200 parts of an organic silicon modified acrylic emulsion, 1-5 parts of a hydrophobic side chain type water-based poly-nitrogen vinegar associative thickener, 400-650 parts of natural stone powder, 1-5 parts of a lotus leaf hydrophobic agent, 50-100 parts of a long-chain silicon oxynitride emulsion, 5-20 parts of a coalescing agent, 1-5 parts of ap-hydroxybenzoate preservative, 1-10 parts of a defoaming agent and 50-100 parts of deionized water. The wear resistance of the hydrophobic layer is improved by compounding multiple hydrophobic layers, and traditional hydrophilic additives such as thickeners and preservatives are changed into hydrophobic additives, so that the water resistance of the coating is improved.

Description

technical field [0001] The invention specifically relates to a real stone paint, in particular to a multi-composite modified hydrophobic real stone paint. 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. It is applied to the imitation stone effect of building exterior walls. The emulsion content is low, and the coating is not tight enough due to the existence of a large amount of sand and stones during film formation, so that the real stone paint is not easily adsorbed tightly with the substrate, and it is easy to take off the paint. Moreover, the traditional real stone paint coating will fade after every rain Whitening, the coating becomes loose, and after the rain stops, the coating returns to its original color after being exposed to the sun. In fact, this is caused by the poor water resistance of the coating and the absorption of water. ...
