PPS纤维拒水防油针刺毡
摘要：
本实用新型公开一种PPS纤维拒水防油针刺毡，该针刺毡为层状结构，在PPS基布的上下表面分别对称粘贴PPS纤维层，在PPS纤维层的表面设置一层聚四氟乙烯保护膜。本实用新型的优点是采用PPS纤维制成针刺非织造材料，耐高温，使用温度可达110-170℃；表面采用聚四氟乙烯混合乳液浸渍镀膜处理，增强抗氧化性和耐酸碱腐蚀性。
摘要（英）：

The utility model discloses a PPS (polyphenylene sulfite) fiber water-repellent oil-proof punched felt, which is in a layered structure. The upper surface and the lower surface of PPS base cloth are respectively symmetrically stuck with a PPS fiber layer, and one layer of polytetrafluoroethylene protection film is arranged on the surface of the PPS fiber layer. The PPS fiber water-repellent oil-proof punched felt has the advantages that the punched non-woven material is made of the PPS fiber, so that the PPS fiber water-repellent oil-proof punched felt resists high temperature, and the use temperature of the PPS fiber water-repellent oil-proof punched felt is 110-170 DEG C. The surface of the PPS fiber water-repellent oil-proof punched felt is dipped and coated by polytetrafluoroethylene mixed emulsion to enhance oxidation resistance and acid and alkali corrosion resistance.
