preparation example 1
[0058] A microencapsulated reinforcing agent is composed of gelatin and dimethicone.
[0059] The microencapsulated reinforcing agent is prepared by the following method:
[0060] S1, add 10kg of dimethylsilicone oil to 20kg of dichloromethane, and stir for 1 hour to obtain a dimethylsilicone oil mixed solution.
[0061] S2, add 25kg polyvinyl alcohol and 15kg sodium dodecyl benzene sulfonate in 90kg water, heat up to 60°C, stir for 40min, cool down to 20°C, then add dimethyl silicone oil mixture, ultrasonically disperse for 20min, stir 9h, and then ultrasonically treated for 20min to obtain an aqueous suspension.
[0062] S3, add 30kg gelatin in 450kg water, now the weight ratio of dimethyl silicone oil and gelatin is 1:3, be warming up to 50 DEG C, stir and process 20min, then add glacial acetic acid and adjust pH value to be 3, obtain gelatin mixed solution.
[0063] S4, adding an aqueous suspension to the gelatin mixture, ultrasonically dispersing for 10 minutes, and sti...
