Embodiment 1
[0022] The specific preparation process of hydrophobic antibacterial coating agent is as follows:
[0023] ①Add 10g of diphenylsilanediol to 170mL of acetone solution, raise the temperature to 100-110°C and stir for 20-30min, then add 2.1g of p-toluenesulfonic acid and 7.2g of cis-aconitic anhydride, and raise the temperature to 250- Reflux at 260°C for 20-22 hours to obtain a polymer solution;
[0024] ②Then lower the temperature in the reaction vessel to 90-95°C, add 7.6g of azobisisobutyronitrile and 15.7g of allyl mercaptan into the reaction vessel at the same time, stir and reflux for 1-2h, then raise the temperature to 120-130°C Reflux for 4-5 hours to obtain a hydrophobic antibacterial coating agent.
Embodiment 2
[0026] The specific preparation process of antibacterial finishing agent is as follows:
[0027] Step 1: Add 11g of resorcinol to 150mL of water, and at the same time add hydrochloric acid to adjust the pH of the solution to 1, then add 8.1g of 37% formaldehyde solution and 16.7g of acetylhydrazide trimethyl chloride to the reaction vessel Ammonium chloride, heated to 60-70°C and stirred for 10-12h, then evaporated to remove the solvent and washed to neutral to obtain phenolic hydroxyl ammonium chloride;
[0028] Step 2: Add 10 g of phenoxyammonium chloride prepared in Step 1 into 80 mL of water and stir to dissolve, then adjust the pH of the solution to 13, then add 3.5 g of formaldehyde solution with a mass fraction of 37% to it, and heat up to 50-60°C Stir the reaction for 2-3h, then add 6.2g of formaldehyde solution with a mass fraction of 37% to the reaction vessel, raise the temperature to 100-110°C for reflux reaction for 5-6h, and then carry out vacuum distillation to ...
