Corrosion-resistant epoxy modified silicone-acrylic stone-like coating

Abstract

The invention discloses a corrosion-resistant epoxy modified silicone-acrylic stone-like coating, and belongs to the technical field of building coatings. The coating comprises a base material servingas a component A and natural colored sand serving as a component B, component A: component B = 25-35: 65-75 according to weight ratio, wherein the component A is prepared from the following raw materials: 46%-50% of epoxy modified silicone acrylic emulsion, 42.05-47.25% of water, 0.7-0.8% of cellulose ether, 0.15-0.2% of clay, 2.7%-3% of 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate, 2.5%-3%of an anti-freezing agent, 0.3%-0.4% of a PH regulator, 0.3%-0.4% of a sterilizing agent and 0.1%-0.15% of a thickening agent, wherein the percentage is weight percentage. The stone-like coating hasthe advantages that the stone-like coating is high in adhesiveness, chemical corrosion resistance and thermal stability, a wall can be effectively protected after the stone-like coating is mixed withnatural colored sand for construction, and the stone-like coating belongs to high-performance environment-friendly products and is simple in construction and smooth in spraying.

Description

【Technical field】 [0001] The invention relates to the technical field of architectural coatings, in particular to a corrosion-resistant epoxy modified silicon acrylic genuine stone paint. 【Background technique】 [0002] In recent years, real stone paint is the preferred product type in the architectural coating industry for exterior wall decoration. The production technology is relatively mature. The products are mainly based on pure acrylic emulsion, styrene modified acrylic emulsion and silicone modified acrylic emulsion. The real stone paint made by mixing natural colored sand of various colors according to the sand gradation ratio has a high degree of similarity with marble, and has a beautiful decorative effect, and has excellent durability and resistance in terms of performance. Cracking performance, among which the minimum film-forming temperature of pure acrylic emulsion is high, and water resistance is poor. High temperature, UV aging resistance and stain resistanc...

[0002] In recent years, real stone paint is the preferred product type in the architectural coating industry for exterior wall decoration. The production technology is relatively mature. The products are mainly based on pure acrylic emulsion, styrene modified acrylic emulsion and silicone modified acrylic emulsion. The film-forming material of the material, the real stone paint made by mixing natural colored sand of various colors according to the sand gradation ratio, has a high similarity with marble, and has a beautiful decorative effect, and has excellent durability and resistance in terms of performance. Cracking performance, among which the minimum film-forming temperature of pure acrylic emulsion is high, and water resistance is poor. High temperature, UV aging resistance and stain resistance, but its adhesion and chemical corrosion resistance are poor, especially with the rapid development of industrialization, the emission of harmful gases is difficult to control, and the emitted gases form acid rain. It is getting more and more serious, so the corrosion resistance performance of real stone paint is put forward higher requirements
