Embodiment 1
[0033] A preparation method of an antibacterial and easy decontamination finishing agent, comprising the following steps:
[0034]Step 1: Mix octamethylcyclotetrasiloxane, octadecyl acrylate, hydroxyethyl methacrylate, butyl acrylate, and 2-hydroxyethyl acrylate in a molar ratio of 1:2:0.7:1.5:0.1 Sequentially add to the container, pass nitrogen gas to deoxygenate, heat and stir, the heating temperature is 60°C, the stirring speed is 600 rpm, and the reaction time is 15 minutes;
[0035] Step 2: Add ethyl acetate and NP-6 in the NP, OP, and TX series of alkylphenol polyoxyethylene ethers, stir and heat up for 3 hours, the stirring speed is 1000 rpm, and the reaction temperature is 120°C;
[0036] The addition amount of ethyl acetate and alkylphenol polyoxyethylene ether is 2% and 10% of the mixed solution quality after the first step reaction
[0037] The third step: naturally cool to room temperature, add an aqueous solution of propylene glycol methyl ether (mass concentrati...
