Example Embodiment
[0024] Example 1:
[0025] First, dissolve 3 parts of triethanolamine borate in 65 parts of water, then add 5 parts of dipropylene glycol, 2 parts of tripropylene glycol, and 5 parts of N-methyldiethanolamine in sequence, mix and stir, then add 20 parts of crude glycerin ( The glycerin content is 80%, which produces biodiesel by-product), and the composite organic grinding aid is obtained after uniform mixing.
Example Embodiment
[0026] Example 2:
[0027] First take 3.5 parts of triethanolamine borate and dissolve in 59 parts of water, then add 6 parts of dipropylene glycol, 4 parts of tripropylene glycol, 5.5 parts of N-methyldiethanolamine in sequence, mix and stir well, then add 22 parts of crude glycerin ( The glycerin content is 80%, which produces biodiesel by-product), and the composite organic grinding aid is obtained after uniform mixing.
Example Embodiment
[0028] Example 3:
[0029] First dissolve 4 parts of triethanolamine borate in 54 parts of water, then add 7 parts of dipropylene glycol, 3 parts of tripropylene glycol, and 6 parts of N-methyldiethanolamine in sequence, mix and stir well, then add 26 parts of crude glycerin ( The glycerin content is 80%, which produces oil by-products), and the composite organic grinding aid is obtained after uniform stirring.
