Embodiment 1
[0039] A bagasse-based water-retaining agent comprises the following components in parts by weight:
[0040] 80 parts of bagasse, 20 parts of waste silk, 15 parts of bagasse biochar, 5 parts of bentonite, 15 parts of sludge, 60 parts of potassium acrylate, 2 parts of crosslinking agent, 1 part of initiator, and 3 parts of polymerization agent.
[0041] The sludge is farm sludge. The crosslinking agent is glycerol. The initiators are hydrogen peroxide and potassium persulfate. The polymerization agent is ammonia water.
[0042] A preparation method of bagasse-based water-retaining agent, comprising the following steps:
[0043] S1. Preprocessing
[0044] 1) Weigh bagasse, crush and pass through a 100-mesh sieve to obtain bagasse powder; add 0.7% H to the bagasse powder 2 o 2 and 4% NaOH mixture, the H 2 o 2 The liquid-to-solid ratio of the mixed solution of NaOH and bagasse is 30:1; stir and react at 85°C for 3-5 hours, then suction filter and dry; then add 31ml / LCH 3 ...
