Embodiment 1
[0059] A kind of non-foaming, low surface tension surfactant, calculated by mass percentage, its raw material composition and content are as follows:
[0060] Active Ingredient A 60%
[0061] Active ingredient B 40%;
[0062] The active component A is PEG400MO, and the PEG400MO is polyethylene glycol monooleate with an average molecular weight of 400;
[0063] The active component B is NP-4, and the NP-4 is nonylphenol polyoxyethylene ether with an average EO number of 4.
[0064] The preparation method of above-mentioned a kind of foam-free, low surface tension surfactant, specifically comprises the steps:
[0065] Add active component A and active component B into the reaction kettle in sequence, control the rotation speed to 80-100r / min and stir evenly to obtain a surfactant with no foam and low surface tension.
