Preferably, the method for modifying of the modified attapulgite clay is as follows：
Step（1）：The purification of attapulgite：Take attapulgite to crush, be crushed to granular size for 2-11 mesh, will be recessed after crushing Convex rod soil is added to the clear water of 10-13 times of attapulgite quality, is stirred, after soaking 12 hours, centrifugal treating 10- 20min, after centrifugation, the first finished product of attapulgite is obtained by filtering, drying steps；
Step（2）：The modification of attapulgite：, will be described using the sodium carbonate liquor that sodium carbonate configuration concentration is 2.5-3.0% The first finished product of attapulgite is put into sodium carbonate liquor, and is stirred and is heated, and described heating-up temperature remains 100-200 ℃；During stirring, sodium acid carbonate and potassium hydroxide pellet are added while stirring, described is added in sodium carbonate liquor Sodium acid carbonate and the quality of potassium hydroxide account for the 2.8-3.5% of sodium carbonate liquor quality；
Step（3）：The processing of attapulgite：
By step（2）The attapulgite of gained obtains modified attapulgite clay by filtering, dry and pulverization process.
Preferably, attapulgite is again modified：
After step（3）Heating operation is carried out to modified attapulgite clay afterwards, described heating-up temperature remains 80-85 DEG C, and stirring makes the pH value of the modification environment of attapulgite remain in 6.2-6.5, described heating process maintains 1.2-2h.
Preferably, attapulgite is again modified：
After step（3）Heating operation is carried out to modified attapulgite clay afterwards, described heating-up temperature remains 80-85 DEG C, and stirring makes the pH value of the modification environment of attapulgite remain in 6.2-6.5, described heating process maintains 1.5h.
On the one hand a kind of preparation method of the air purification filter paper containing attapulgite clay provided, it is described glutinous containing concave convex rod The preparation method of the air purification filter paper of soil is as follows：
Step（1）：Slurrying：Average diameter is beaten for 0.35-4.5um glass fibre cotton in the aqueous solution for add hydrochloric acid It is scattered, and the mass concentration of slurry is controlled for 3.0-3.3%；
Step（2）：Wet moulding：By step（1）Obtained pulp dilution is to mass concentration is 0.3-0.35% and removes the gred, then Wet moulding is carried out with paper machine, l Water Paper is obtained；
Step（3）：Spray antimicrobial gluing liquid：Quaternary ammonium salt, halogenated amine, chitosan are sprayed to wet paper surface using spraying equipment and is changed Property attapulgite clay composition antibacterial gluing solution；
Step（4）：Suction dehydration：First to step（3）The l Water Paper of spraying gluing liquid is sucked by vacuum so that antibiosis rubber mucus Above and below being distributed between two fibre layers；So that two layers of fibre compact is combined, the moisture content ＜ 35% of l Water Paper；Vacuum degree control exists 0.05-0.1MPa；
Step（5）：Two-sided applying glue：Simultaneously to step（4）The outer surface of dewater treatment l Water Paper is glued；
