Embodiment 1
[0025] a. Preparation of coupling agent hydrolyzate
[0026] Mix 20 parts of KH602 and 18 parts of water in a closed four-necked flask and stir at a constant speed for hydrolysis, the hydrolysis temperature is 10°C, and the hydrolysis time is 2 hours; then maintain at -0.09MPa for 1 hour to remove low-molecular compounds; the viscosity obtained after standing still is 300mPa·s (25°C) KH602 hydrolyzate mainly composed of silicon glycol.
Embodiment 2
[0028] a. Preparation of coupling agent hydrolyzate
[0029] Mix 18 parts of KH602 and 13.5 parts of water in a closed four-necked flask and stir at a constant speed for hydrolysis, the hydrolysis temperature is 15°C, and the hydrolysis time is 1h; then maintain at -0.09MPa for 1h to remove low-molecular compounds; the viscosity obtained after standing still is 200mPa·s (25°C) KH602 hydrolyzate mainly composed of silicon glycol.
Embodiment 3
[0031] a. Preparation of coupling agent hydrolyzate
[0032] Mix 17 parts of KH602 and 9 parts of water in a closed four-necked flask and stir at a constant speed for hydrolysis. The hydrolysis temperature is 12°C and the hydrolysis time is 1.5h; then maintain at -0.09MPa for 1h to remove low-molecular compounds; stand still to get the viscosity It is KH602 hydrolyzate mainly composed of silicon glycol at 100mPa·s (25°C).
