9. the preparation method of Wall paper adhesive of the one kind according to any one of claim 1 ~ 8, it is characterised in that including following step
Suddenly：
（1）, prepare modified starch
First, starch, sodium citrate and sodium ethylene diamine tetracetate are weighed according to proportioning, is added to the water and heats, heating-up temperature control
40 ~ 50 DEG C are made as, dissolving 10 ~ 40min of stirring is cooled to 15 ~ 20 DEG C and obtains starch milk；
Secondly, weigh aqueous slkali and be slowly added in the foregoing starch milk for obtaining, the pH for adjusting starch milk is 12.0 ~ 12.2, then
Sodium trimetaphosphate is added, 1 ~ 4h of reaction under the conditions of 20 ~ 40 DEG C is well mixed, acetic anhydride is so added dropwise, by the pH value of starch milk
Being adjusted to 8.2 ~ 8.3 carries out acetylization reaction, after completion of dropping, continues to react 30 ~ 60min, obtains modified starch slurry；
Finally, by the foregoing modified starch slurry for obtaining it is scrubbed, dehydration, dry, obtain the modified starch；
（2）, prepare camphortree leaf leaching liquor
Camphortree leaf is taken out according to proportioning, 120 ~ 130 mesh sieves was crushed and is obtained camphortree leaf, add 6 ~ 10 times of distilled water of weight portion,
It is subsequently adding acid-base modifier to adjust to 4 ~ 6 pH value, is put into 6 ~ 8h of extraction in 60 ~ 110 DEG C of thermostat water baths, uses gauze mistake
Filter, retain filtrate, filter residue is extracted again in the same way, is filtered, will twice extract gained filtrate conjunction and obtain camphortree leaf extraction
Liquid, it is standby；
（3）, raw material mixing
Surplus stock is weighed, step is mixed into（1）The modified starch and step for obtaining（2）In the camphortree leaf leaching liquor for obtaining, put
In entering reaction vessel, 40 ~ 60min of dispersed with stirring, after will to be heated up in temperature be 90 ~ 95 DEG C, continue to stir with 300 ~ 400r/min
20 ~ 30min, stirring obtains colloid discharging after naturally cooling to 20 ~ 35 DEG C after terminating, pulse strong-light technology is used simultaneously in discharging
Surface disinfection is carried out to colloid, is packed, obtain the Wall paper adhesive.
