Abstract
The invention discloses a production method of a polytetrafluoroethylene anti-dripping agent. The production method comprises the following steps of (1) adding ethylenediamine-polyoxyethylene-polyoxypropylene block polyether, 2-hexyl-1-decanol, kaolin, potassium persulfate, calcium carbonate, benzoyl peroxide, deionized water, ammonium peroxydisulfate, butyl methacrylate, maleic anhydride, tartaric acid and triethanolamine in a reaction kettle, heating to 72 DEG C, and reacting by stirring; (2) adding potassium persulfate, deionized water, benzoyl peroxide, butyl methacrylate, maleic anhydride and ammonium peroxydisulfate in the reaction kettle, heating to 80 DEG C, and reacting by stirring; (3) adding polytetrafluoroethylene dispersion liquid and deionized water into the reaction kettle, blending and compounding by heating, and adding a flocculant solution at the temperature of 55 DEG C to obtain a sediment; and (4) centrifugally separating the sediment, washing the sediment with water, centrifugally separating the sediment again, drying and smashing to obtain the anti-dripping agent. The polytetrafluoroethylene anti-dripping agent prepared by using the production method is good in stability.
Description
Technical field
The present invention relates to the production method of tetrafluoroethylene anti-dripping agent.
