[0029] Example 1
[0030] The preparation of non-adhesive skin care antibacterial microcapsule finishing agent includes the following steps:
[0031] (1) Take 5g of aloe vera extract, 5g of squalene and 1g of Tween-20 respectively, add them to 500g of deionized water, and ultrasonically stir at 50°C for 30min to obtain a core material emulsion, control the ultrasonic frequency to be 300W, and the stirring rate to be 1500r / min ;
[0032] (2) prepare a TEOS aqueous solution of 20% concentration, adjust the pH to 3 with 2 mol / L hydrochloric acid, and stir at 30° C. for 25 min to obtain a wall material hydrolyzate, and the stirring rate is 300 r / min;
[0033] (3) 50g of wall material hydrolyzate was slowly added dropwise to 500g of core material emulsion, the pH was adjusted to 9 with 2mol / L NaOH solution, stirred at 50°C for 4h, filtered and washed, and dried at 60°C to obtain white microcapsule solids. The acceleration is 20 drops / min, and the stirring rate is 500 r / min;
