Embodiment 1
[0037] (1) Method (1) Preparation of siloxane haloamine compound / nano-titanium dioxide finishing solution:
[0038] Add 5,5-dimethyl-3-(3'-triethoxysilylpropyl)-hydantoin to the mixed solution of ethanol and water with a mass ratio of 1:0.8 to make it dissolve in the mixed solution of ethanol and water The final concentration in the solution is 6wt%; or add 5,5-dimethyl-3-(3'-triethoxysilylpropyl)-hydantoin polymer to make its final concentration in the mixed solution of ethanol and water The concentration is 4wt%; stir to form a transparent liquid; then add nano-titanium dioxide so that the final concentration in the mixed solution of ethanol and water is 3wt%, and ultrasonically vibrate for 10 minutes to obtain the product;
[0039] The preparation method of the 5,5-dimethyl-3-(3'-triethoxysilylpropyl)-hydantoin is:
[0040] Mix equimolar amounts of 5,5-dimethylhydantoin and sodium hydroxide in absolute ethanol, react at 90°C for 8 minutes, remove the solvent ethanol and dry ...
