The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
The method that the present invention adopts butyl titanate that nylon fabric is carried out modification, specifically implement according to following steps:
Step 1: the nylon fabric that will treat modification temperature be under 60～90 ℃ of conditions respectively with deionized water and concentration be 95% absolute ethyl alcohol repeatedly sonic oscillation clean dry for standby then.
Step 2: take by weighing nylon fabric and butyl titanate after the processing that step 1 obtains according to mass ratio 1～3:1, volume ratio with 1:20～100 is dissolved in deionized water with the butyl titanate that takes by weighing, obtain butyl titanate solution, then the nylon fabric that takes by weighing is immersed in 5～10min in the butyl titanate solution, subsequently the butyl titanate solution that is impregnated with nylon fabric is added in the high-temperature high-pressure reaction kettle, and be filled to 60～80% of reactor volume with deionized water, sealing, reactor constant temperature under 110～140 ℃ of conditions of good seal is handled 3～6h, and question response finishes the back and takes out nylon fabric.
