The invention belongs to the technical field of surfactants, and relates to a Gemini type surfactant as well as a preparation method and application thereof. The molecular structural formula of the Gemini type surface active agent is as follows: the Gemini type surface active agent is prepared from the following raw materials in molar ratio: cocoyl propyl dimethyl tertiary amine, octadecylamine, an alcohol solvent, acrylamide, epoxy chloropropane and hydrochloric acid in the molar ratio of 1: (1.00 to 1.05): (21.0 to 35.0): (2.00 to 2.20): (1.00 to 1.15): (1.00 to 1.15). The Gemini type surfactant provided by the invention can be applied as a foam inhibitor, a low-foam surfactant and/or an emulsifier. 本发明属于表面活性剂技术领域，涉及一种Gemini型表面活性剂及其制备方法与应用，所述Gemini型表面活性剂的分子结构式为：该Gemini型表面活性剂是由以下摩尔配比的原料制备而成：椰油酰基丙基二甲基叔胺、十八胺、醇类溶剂、丙烯酰胺、环氧氯丙烷、盐酸的摩尔比为1：(1.00～1.05)：(21.0～35.0)：(2.00～2.20)：(1.00～1.15)：(1.00～1.15)。本发明的Gemini型表面活性剂可作为抑泡剂、低泡性表面活性剂和/或乳化剂应用。
