Water-based environment-friendly waterproof coating and preparation method thereof
The invention discloses a water-based environment-friendly waterproof coating and a preparation method thereof. The waterproof coating is formed by mixing a liquid material and a powder material, wherein the liquid material is composed of the components in percentage by weight: 85%-90% of a fluorocarbon emulsion, 1%-2% of a modifier, 0.3%-0.5% of a catalyst, 3%-8% of a coalescing agent, 0.1%-0.5%of a surfactant, 0.1%-0.3% of a defoaming agent, 3%-8% of deionized water and 0.3%-0.8% of cellulose ether; the powder comprises the components in percentage by weight: 50%-70% of silicate mineral powder, 10%-30% of quartz powder and 10%-30% of bentonite. The problems that an existing polymer emulsion waterproof coating is not high in mechanical property strength, poor in weather resistance and ultraviolet resistance, poor in pollution resistance (self-cleaning property), poor in stability and prone to precipitation after being stored and transported in a high-temperature environment for a long time, and an existing waterproof coating filling material and a film forming material are structurally separated are solved.
本发明公开了一种水性环保防水涂料及其制备方法，所述防水涂料由液料和粉料混合而成，所述液料包括重量比例85%‑90%的氟碳乳液、重量比例1%‑2%的改性剂、重量比例0.3％‑0.5％的催化剂、重量比例3％‑8％的成膜助剂、重量比例0.1%‑0.5%的表面活性剂、重量比例0.1%‑0.3%的消泡剂、重量比例3％‑8％的去离子水、重量比例0.3%‑0.8%的纤维素醚；所述粉料包括重量比例50%‑70%的硅酸盐矿粉、重量比例10%‑30%的石英粉、重量比例10%‑30%的膨润土。本发明解决了现有聚合物乳液防水涂料力学性能强度不高、耐候性能、抗紫外性能差、抗污性能(自洁性)差、稳定性差，长期高温环境储存和运输容易产生沉淀的问题，以及现有防水涂料填充材料与成膜材料结构分离的问题。
