Polypropylene spinning oil agent and manufacturing method thereof

The invention discloses a polypropylene spinning oil agent, which consists of the following formulation raw materials in percentage by weight: 65 to 75 percent of smoothing agent, 2 to 8 percent of dispersant, 15 to 25 percent of bundling agent and 2 to 8 percent of additive. The dispersant is one or a mixture of castor oil polyethenoxy ether and lauryl alcohol polyethenoxy ether; and the dispersant also comprises not less than 20 percent of fatty acid alkylolamide in percentage by weight. A manufacturing method comprises the following steps: firstly pumping the bundling agent and the dispersant into a reaction kettle, heating the mixture to between 40 and 80 DEG C, stirring the mixture evenly, pumping the smoothing agent into the reaction kettle, stirring the mixture for 30 to 50 minutes, then adding the additive into the mixture, stirring the mixture evenly, and cooling, filtering and packing the mixture. Because the fatty acid alkylolamide is added into the dispersant, the polypropylene spinning oil agent avoids adopting alkylphenol polyoxyethylene, the cohesive force of the oil agent is ensured, and the requirement of ecological environment on the oil agent is met.
