摘　　要：食品防油纸是食品包装纸中的一大类,食品防油纸要求具有防油性能,同时对物理强度、抗水性能、防黏性能、印刷适应性和卫生指标都有一定要求。不同于覆膜防油纸和含氟防油纸,本文通过研究不同种类的环保防油剂,制备出丙烯酸酯类复配环保防油剂,并将其应用到食品防油纸生产中。确定优选丙烯酸酯类环保防油剂(丙2)为防油涂层的主要原料,丙烯酸酯类环保防油剂(丙2)和淀粉的最优配比为1∶1,此时纸张的防油等级为12级。成功应用于中试生产,中试环保防油纸和含氟防油纸相比,防油等级和耐热油性能达到最高要求,抗张指数和撕裂指数优于含氟防油纸,吸水性、透气率、生产成本和含氟防油剂相近,证明了环保防油剂复配的可靠性。其性能指标:抗张指数(纵向)91.35 N.m/g,撕裂指数(横向)8.86 m N.m^(2)/g,平滑度(正面/反面)38 s/23 s,吸水性(正面)10.2 g/m^(2),透气率1.65 mm/s。Greaseproof paper is a widely used packaging material in food packaging industry.Greaseproof food wrap paper requires a certain grease resistant performance,physical strength,waterproof properties,anti-peeling properties,printability and health indicators.The environmental greaseproof food wrap paper discussed in this paper is different from coated and fluorinated greaseproof paper.It is degradable and does not contain fluorine greaseproof agent.This paper mainly studies the effects of the types and dosage of environmental greaseproof agent on the properties of greaseproof paper.Acrylic ester compound environmental greaseproof agent was prepared and applied to the production of greaseproof food wrap paper.Experimental results showed that the acrylic ester environmental greaseproof agent(Propylene 2) can be used as the main raw material of greaseproof coating.Greaseproof paper can obtain 12 grades of oil grade when the optimal ratio of acrylic ester environmental greaseproof agent(Propylene 2) and starch is 1:1.Acrylic ester compound environmental greaseproof agent has been successfully applied in pilot production.Compared with fluorinated greaseproof paper,the greaseproof grade and heat-resistant oil performance of the environmental greaseproof food wrap paper reach the highest requirements.The tensile index and tear index of the environmental greaseproof food wrap paper are better than those of fluorinated greaseproof paper.Water absorption,air permeability,production cost of the environmental greaseproof food wrap paper is similar with fluorinated greaseproof paper.It proved that the acrylic ester compound environmental oilproofing agent is reliable in the production of greaseproof paper.The tensile index(MD) is 91.35N·m·g~(-2),the tear index(CD) is 8.86mN·m^(2)·g~(-1),the smoothness(front/back) is 38/23s,the absorption value is 10.2g·m~(-2) and the air permeability is 1.65mm·s~(-1).
