Stir process 5-10 minutes, then ferrous sulfate is added into agitator tank, and continue to stir 2-3 minutes；
2）Sodium hydroxide is put into agitator tank, is stirred when adding, 0.9-1 hours is carried out in stirring reaction, adds
Tributyl phosphate defoamer, the moisturizing in agitator tank after foam largely disappears；
3）The borax into reaction pot is added during the moisturizing into agitator tank, agitator tank device temperature is warming up to 65-75 DEG C, entered
Row stirring 15-20 minutes, survey its viscosity of mixed liquid for 60 seconds when；
4）Sodium thiosulfate is added in most backward agitator tank, is added under agitation in above-mentioned reaction mass, so that reaction terminating, system
It is standby to terminate.
Beneficial effect is：Add cornstarch in the adhesive prepared in the present invention, and by cornstarch and peroxidating
Hydrogen carries out oxidation processes in sodium hydroxide solution, so as to improve the bonding force of starch and anti-corrosion, mould proof ability；The opposing party
Face, oxidation can reduce the degree of polymerization of starch molecule, its strand is shortened again, make obtained adhesive flow good.
