摘要:采用磷系阻燃剂制备内燃机用阻燃型空气滤纸，并用三聚氰胺甲醛树脂替代部分苯丙乳液进行增强，研究其对阻燃剂用量的影响。结果表明，15%的三聚氰胺甲醛树脂和85%的苯丙乳液进行复配后，阻燃剂的留着率在14%时即可获得优异的阻燃性能，可节约22%的阻燃剂用量，且不会降低滤纸的力学性能。

Abstract:The fire-retardant air filter paper for internal-combustion engine was prepared by using phosphorus flame retardant, part of styrene-acrylic emulsion was replaced by melamine formaldehyde resin, and the role played by melamine formaldehyde resin was studied in this paper. The results showed that: when the emulsion was replaced by 15% melamine formaldehyde resin, the flame retardant properties was excellent when the retention rate of the flame retardant was 14%, 22% flame retardant was saved, while the mechanical properties of the filter paper would not reduced.
