一种耐沾污涂层及其制备方法
摘要：
本发明公开了一种耐沾污涂层及其制备方法，包括PE胶底部涂层和耐沾污涂层，所述PE胶底部涂层为在基底涂刷，用于基底与耐沾污涂层的粘接；所述PE胶底部涂层的制作原料包括PE胶20-30份、消泡剂1-3份、成膜助剂5-10份、二甲苯65-76份；耐沾污涂层的制作原料包括氟碳乳液40-45份、氟改性有机硅树脂12-18份、重质碳酸钙5-8份、消泡剂1-3份、成膜助剂4-8份、耐沾污助剂3-8份。本发明的优点在于排水管材的内壁涂刷了PE胶底部涂层和耐沾污涂层，使得排水管材具有良好的耐沾污性能，延长了排水管材的使用寿命。
摘要（英）：

The invention discloses a stain-resistant coating and a preparation method thereof. The stain-resistant coating is prepared from a PE glue bottom coating and a stain-resistant coating, wherein the PEglue bottom coating is applied to a substrate and is used for bonding the substrate with the stain-resistant coating; the PE glue bottom coating is prepared from 20-30 parts of PE glue, 1-3 parts of an anti-foaming agent, 5-10 parts of a coalescing agent and 65-76 parts of xylene; the stain-resistant coating is prepared from 40-45 parts of fluorocarbon emulsion, 12-18 parts of fluorine-modified organic silicon resin, 5-8 parts of heavy calcium carbonate, 1-3 parts of an anti-foaming agent, 4-8 parts of a coalescing agent and 3-8 parts of a stain-resistant auxiliary. The stain-resistant coatingdisclosed by the invention has the following advantages that the inner wall of a drain pipe is coated with the PE glue bottom coating and the stain-resistant coating, thus the drain pipe has high stain resistance, and the service life of the drain pipe is prolonged.
