植物油滤纸及其制备方法和应用
摘要：
本发明提供了一种植物油滤纸，包括原纸和对原纸进行浸渍的浸渍剂，所述的原纸用到的纤维按重量份数计包括玉米秸秆纤维30‑50份，聚丙烯纤维5‑12份和无碱玻璃纤维短切丝8‑15份，原纸制备中用到两性聚丙烯酰胺0.05‑2份，改性淀粉轻质碳酸钙0.2‑0.8份，具有250万～300万分子量的聚氧化乙烯0.05‑3份，消泡剂0‑0.2份；所述的浸渍剂为改性的酚醛树脂。该植物油滤纸具有耐磨、耐腐蚀、耐高温、平均空隙率高、过滤吸收性能好、使用寿命长、干湿强度高及纸质均匀的特性。
摘要（英）：

The present invention provides vegetable oil filtration paper, which comprises raw paper and an impregnating agent for impregnating the raw paper, wherein the fibers used in the raw paper comprise, by weight, 30-50 parts of corn straw fibers, 5-12 parts of polypropylene fibers, and 8-15 parts of alkali-free glass fiber short-cutting fiber, 0.05-2 parts of amphoteric polyacrylamide, 0.2-0.8 part of modified starch light calcium carbonate, 0.05-3 parts of polyoxyethylene having a molecular weight of 2500000-3000000, and 0-0.2 part of a defoamer are used in the raw paper preparation, and the impregnating agent is a modified phenol formaldehyde resin. The vegetable oil filtration paper of the present invention has characteristics of abrasion resistance, corrosion resistance, high-temperature resistance, high average porosity, good filtration absorption performance, long service life, high wet and dry strength, and uniformity.
