Embodiment 1
[0023] The preparation method of water-retaining agent, concrete steps are as follows:
[0024] 1. After dedusting the crop straws, use a pulverizer to crush them, and pass through a 40-mesh sieve to obtain coarse powder;
[0025] 2. Slowly add 60g of acrylic acid to 117ml of 30% potassium hydroxide solution in an ice-water bath for neutralization, and stir at room temperature for 30 minutes to prepare an acrylate solution with a neutralization degree of 75%;
[0026] 3. Mix 66g of wheat flour and 34g of pretreated straw powder, add 750ml of water to make slurry, heat up to 80°C, gelatinize for 30min, cool down to 60°C, slowly add acrylate with a neutralization degree of 70% Solution, after mixing evenly, add initiator-ammonium persulfate 3g, after stirring for 5min, add cross-linking agent-N,N-methylenebisacrylamide 5g, polymerize for 15min, form a mesh structure, immerse in 300ml 0.9% Soak in salt water for 30 minutes to get water retaining agent;
[0027] 4. Wash the wate...
