摘　　要：优选氟碳弹性乳液作为氟碳弹性涂料的成膜物质,以碳酸钙、钛白粉等填料增加涂膜硬度,同时按功能需求搭配适量消泡剂、增稠剂、pH调节剂、润湿剂等助剂,研制出一种具有良好耐沾污、透气性及弹性性能的高性能氟碳弹性涂料。研究了乳液、填料、遮盖聚合物、硅藻土等用量对氟碳外墙涂料性能的影响,并对其性能进行了检测。结果表明:选用氟碳弹性乳液60份、气相二氧化硅1份、遮盖聚合物3份、硅藻土4份,按此配方可研制出具备优异性能的氟碳涂料,该涂料的拉伸强度、断裂延伸率、耐沾污性、耐洗刷等性能均符合JG/T 172-2005标准的要求。A high-performance new fluorocarbon elastomeric coating with excellent anti-staining, anti-aging and elastic properties was prepared by the fluorocarbon elastic emulsion as a film-forming substance, and the hardness of the paint film increased by fillers such as calcium carbonate and titanium white powder, and at the same time, an appropriate amount of defoaming agent, thickener, pH detecting agent and wetting agent matched according to functional requirements. The effects of the amount of raw materials such as emulsion,filler, cover polymer and diatomaceous earth on the properties of fluorocarbon exterior wall coatings were investigated and their properties were tested. The results showed that 60 parts of fluorocarbon elastic emulsion, 1 parts of vapor phase SiO2 filler, 3 parts of polymer cover, and 5 parts of diatomite were added.According to this formula, a fluorocarbon coating with excellent properties can be developed. Strength,elongation at break, stain resistance, artificial aging resistance, etc., in line with JG/T 172-2005 standard requirements.
