10. a kind of preparation method of multi-functional environment-protection water treatment agent as claimed in any one of claims 1 to 9, feature exist
In: the following steps are included:
Step a, the preparation of modified nanometer cellulose quaternary ammonium salt mixed liquor:
First nano-cellulose is dispersed in tetrahydrofuran-sodium hydroxide mixed solution, is heated to 50-60 DEG C, stirring pretreatment
Then chloroacetic acid is added in 1-2h, 4-6h is reacted at 60-80 DEG C, hydrochloric acid solution tune pH to 7 is added, then in stirring condition
Lower addition initiator, then it is gradually added into polyquaternium, and react 3-6h at 60-80 DEG C, obtain modified nanometer cellulose quaternary ammonium
Salt mixed liquor；
In the step, the nano-cellulose: chloroacetic acid: the mass ratio of polyquaternium is 1:(0.5~2): (1~5), it is described
Initiator amount is the 0.01-0.2% of nano-cellulose gross mass；
Step b, the preparation of oxidation nanometer cellulose mixed liquor:
Nano-cellulose, isopropyl alcohol and water are added in a kettle, is heated to 70-90 DEG C of stirring 0.5-1h, then under stiring
After ferrous sulfate is added, it is slow added into hydrogen peroxide, 1-3h is reacted, obtains oxidation nanometer cellulose mixed liquor；
In the step, the mass ratio of the hydrogen peroxide and nano-cellulose is (20~75): 100, the ferrous sulfate and nanometer
Cellulose mass ratio is (0.8~2.6): 100；
Step c, the preparation of alkylamine emulsion:
It first by alkylamine and emulsifier heating melting and stirs evenly, is slow added into water, after mixing evenly, obtains alkylamine cream
Change liquid；
In the step, the mass ratio of the alkylamine, emulsifier and water is (3~50): (1~10): (40~96)；
Step d, it mixes:
By formula ratio, the modified nanometer cellulose quaternary ammonium salt mixed liquor prepared, oxidation nanometer cellulose are mixed respectively
Liquid, alkylamine emulsion and betaine type amphoteric surfactant are placed in reaction kettle, and 0.5-1h is stirred at 15-35 DEG C, and stirring is equal
After even to get arrive the multi-functional environment-protection water treatment agent.
