Foaming type degradable water surface oil spill dispersant and preparation method thereof

[0025] (1) Get tartaric acid (acid agent) 150g, cross 40 mesh sieves, add the starch slurry (binder) 15g that mass fraction is 10%, granulate with granulator, cross 10 mesh sieves, air-dried at 45 ℃ 5h, to obtain dry acid agent granules;

[0026] Take 125g of sodium bicarbonate (alkaline agent), pass through a 50-mesh sieve, add 15g of starch slurry (adhesive) with a mass fraction of 10%, granulate with a granulator, pass through a 10-mesh sieve, and air-dry at 45°C for 5 hours , to obtain dry alkaline agent granules.

[0027] (2) Add 35g of alkyl glycoside APG0810 (nonionic surfactant) to the dried alkaline agent granules, 50g of sodium lauryl sulfate (anionic surfactant), 110g of sodium sulfate (filler), mix well, and dry, Add dry acid agent granules, and mix evenly again to obtain a foamable degradable water surface oil spill dispersant according to the present invention.

[0029] (1) Take 50g of citric acid (acid agent), pass through a 80-mesh sieve, add 10g of polyethylene glycol 6000 (binder), granulate with a granulator, pass through a 12-mesh sieve, and air-dry at 40°C for 18 hours. Obtain dry acid agent granules;

[0030] Take 25g of sodium bicarbonate (alkaline agent), mix and pass through a 50-mesh sieve, add 10g of polyethylene glycol 6000 (binder), granulate with a granulator, pass through a 10-mesh sieve, and air-dry at 45°C for 5 hours. Obtain dry alkali agent granules.

[0031] (2) Add dimethyl-9-decenamide (nonionic surfactant) 60g, α-olefin sulfonate sodium (anionic surfactant) 120g, sodium sulfate (filler) 225g in the dry alkaline agent granule , after mixing evenly, drying, adding dry acid agent granules, and mixing evenly again to obtain a foamable degradable water surface oil spill dispersant according to the present invention.

[0033] (1) get tartaric acid (acid agent) 60g and citric acid (acid agent) 40g to mix, cross 50 mesh sieves, add 15g mass fraction and be 10% polyvinylpyrrolidone ethanol solution (binding agent), granulate with granulator , passed through a 10-mesh sieve, and air-dried at 45°C for 8 hours to obtain dried acid agent granules;

[0034] Take 80g of sodium bicarbonate (alkali agent), pass through a 50-mesh sieve, add 8g of polyethylene glycol 6000 (binder), granulate with a granulator, pass through a 10-mesh sieve, and air-dry at 45°C for 8 hours to obtain dry alkaline agent granules.

[0035] (2) Add dimethyl-9-decenamide (nonionic surfactant) 50g to the dry alkaline agent granules, rhamnolipid (anionic surfactant) 160g, sodium chloride (filler) 150g, After mixing evenly, dry it, add dry acid agent granules, and mix evenly again to obtain a foamable degradable water surface oil spill dispersant according to the present invention.
