The preparation method of described filter of automobile engine air paper, comprises the following steps:
(1) first modified zeolite molecular sieve, kaolin, nano-sized carbon, milk of lime are uniformly mixed, then add silane coupler DL171, after fully stirring 10-20min, leave standstill 5-8min, then dry at 100-120 DEG C, obtain powder body material;
(2) hardwood pulp, cotton pulp, modified polyester fibre are weighed by proportioning respectively, put into pulper, adding appropriate sulfuric acid water size degradation is the slurry of 5-6% to solid content, adds dialdehyde starch and continues size degradation 1-2h, make mixed slurry;
(3) powder body material that step (1) makes is added in mixed slurry, add hydrotalcite powder, sldium lauryl sulfate, sldium lauryl sulfate, be heated to 70-80 DEG C, stir, after fluffer is discongested, then defibrination, add appropriate water size mixing to solid content be 2-3%, the slurry mixed up, after forming web is shaping, carries out suction dehydration to the l Water Paper after shaping under the vacuum condition of 0.05-0.08Mpa;
(4) dilution 10-20 after acrylic emulsion and polyvinyl acetate emulsion mixing is doubly made maceration extract, the paper after dehydration is dipped in maceration extract and floods 2-3h, then remove excessive maceration extract with pressure roll;
(5) paper after dipping is dried to mass dryness fraction 95-98% at 180-200 DEG C, press polish and arrange and obtain filter of automobile engine air paper of the present invention.
The present invention and prior art have following beneficial effect:
The present invention, by the modification to polyster fibre and modified zeolite molecular sieve, improves the absorption property of filter paper, strainability, thus improves the filtering efficiency of filter paper, and modified polyester fibre also improves the mechanical property such as tensile strength, bursting strength of filter paper simultaneously.The filter paper that the present invention prepares has good water permeability, filter area is large, maximum diameter of hole is little, filtering accuracy is high, resistance to water is high, bursting strength is strong, high temperature resistant, etc. advantage, filter efficiency reaches 99.98%, under normal temperature and worst hot case, there are stable performance indications, there is good resistance to gentle filter effect.
