[0043] The second aspect of the present invention provides the preparation method of described nonionic surfactant, comprises the following steps:
[0044] Put the polymer containing EO group into the reaction kettle and heat up to 70-90°C to melt. After completely melting, heat up to 110-130°C and vacuum for 1-3 hours, then cool down to 70-90°C and add isocyanate and chain extender. After reacting for 3-5 hours, add a dialkylamine with 24-44 carbon atoms to continue the reaction for 4-6 hours, add an auxiliary agent and a catalyst, and react for 1-3 hours.
[0045] The catalyst is selected from one of organic bismuth, organic tin and organic zinc; preferably, the weight of the catalyst is 0.1-0.5% of the weight of the nonionic surfactant.
[0046] The third aspect of the present invention provides an emulsion comprising the nonionic surfactant, wherein, calculated by weight percentage, the nonionic surfactant is 4-8%; hydrocarbon resin is 40-70%; quantity.
[0047] The emul...
