Embodiment 1
[0020] Embodiment 1: described defoamer is formulated by the raw material of following mass parts: 30 parts of glycerine type dendritic polyethers, 40 parts of octadecyl alcohol stearates, 25 parts of coking wax oils, 5 parts of isooctyl alcohols share. The above raw materials are mixed and stirred at 80°C for 2 hours, and the finished product is obtained after cooling.
Embodiment 2
[0021] Embodiment 2: described defoamer is formulated by the raw material of following mass parts: 40 parts of glycerol type dendritic polyethers, 15 parts of ethylenediamine bisstearamides, 15 parts of ethylenediamine monooleic acid amides, coking 30 parts of wax oil. The above raw materials are mixed and stirred at 100°C for 2 hours, and the finished product is obtained after cooling.
