Multi-composite modified hydrophobic stone-like coating and preparation method thereof
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.
本发明公开了一种多复合改性疏水真石漆及其制备方法，包括如下重量份的原料制备而成：包括有机硅改性丙烯酸乳液100‑200份、疏水侧链型水性聚氮醋缔合型增稠剂1‑5份、天然石粉400‑650份、荷叶疏水剂1‑5份、长链硅氧氮烷乳液50‑100份、成膜助剂5‑20份、对羟基苯甲酸酯类防腐剂1‑5份、消泡剂1‑10份、去离子水50‑100份；本发明通过复合多层疏水层提高疏水层的耐磨性，将传统亲水性的增稠剂、防腐剂等添加料改为疏水性的添加料，提高涂层的耐水性。
