Natural stone imitated stain-resistant water permeable brick and preparation method thereof
The invention relates to a natural stone imitated stain-resistant water permeable brick and a preparation method thereof. The natural stone imitating stain-resistant water permeable brick comprises a brick body, wherein the surface of the brick body is coated with stone imitating paint; the stone-like coating is prepared from the following raw materials in parts by weight: 20-30 parts of phenolic resin powder; 10-14 parts of a fluorocarbon emulsion; 6-8 parts of polylactic acid; 4-5 parts of modified magnesium aluminum hydrotalcite; 3-4 parts of 2-methoxy ethyl acetate; 8-9 parts of an inorganic pigment; 5-7 parts of deionized water; 1-2 parts of a coalescing agent; the invention relates to a preparation method of a natural stone imitating stain-resistant water permeable brick. The preparation method comprises the following steps: preparing a stone imitating coating; preparing a brick body; and spraying a stone-like coating to finally obtain the stone-like water permeable brick. The pollution-resistant stone-like coating prepared by mixing the phenolic resin powder and the fluorocarbon emulsion is adopted; particles of the modified magnesium-aluminum hydrotalcite improve the regularity of the coating and the flatness of the surface, increase the contact angle between a pollution source and the coating, and are mixed with polylactic acid to form a uniform physical net structure, so pollutants are not easy to adhere, and the pollution resistance of the water permeable brick is improved.
本申请涉及一种仿天然石材的耐污透水砖及其制备方法；一种仿天然石材的耐污透水砖，包括表面涂覆仿石材涂料的砖体；仿石材涂料的原料包括如下重量份数的组分：20‑30份酚醛树脂粉；10‑14份氟碳乳液；6‑8份聚乳酸；4‑5份改性镁铝水滑石；3‑4份2‑甲氧基乙基乙酸酯；8‑9份无机颜料；5‑7份去离子水；1‑2份成膜助剂；一种仿天然石材的耐污透水砖的制备方法，包括制备仿石材涂料；制备砖体；喷涂仿石材涂料，最终得到仿石材透水砖。本申请采用酚醛树脂粉和氟碳乳液混合的耐污染仿石材涂料；改性镁铝水滑石的粒子提高涂层的规则度和表面的平整性，增加污染源与涂层的接触角，并与聚乳酸混合形成统一的物理网状结构，污染物不易沾黏，提高透水砖的耐污性。
