Environment-friendly polypropylene filament yarn oil agent and production method thereof

The invention discloses a preparation method of an environment-friendly polypropylene filament yarn oil agent, comprising the following steps of: weighing 40 to 60 parts by weight of fatty alcohol ether phosphate potassium salt, 2 to 8 parts by weight of polysiloxane polyether copolymer, 3 to 12 parts by weight of pentaerythritol oleate, 4 to 10 parts by weight of fatty alcohol polyoxyethylene ether, 2 to 12 parts by weight of ethylene oxide-epoxypropane block polyether, 20 to 45 parts by weight of polyethylene glycol laurate, 10 to 20 parts by weight of butter alcohol amine phosphate salt and 5 to 10 parts by weight of high-carbon heterogeneous alcohol phosphate potassium salt, heating to 40 to 80 DEG C, reacting under the stirring condition, then adding 20 to 40 parts of emulsifying agent EL-40, 1 to 5 parts of methyl-1-hydroxyethyl-2-stearyl imidazoline ammonium methosulfate, 5 to 15 parts of dimethyl silicon oil, 2 to 40 parts of deionized water and 0.001 to 0.02 part of preservative, reacting under the stirring condition at 50 to 70 DEG C, and separating to obtain the environment-friendly polypropylene filament yarn oil agent.
