Abstract
The invention discloses a preparation process of an anti-dripping agent with high stability. The preparation process comprises the following steps of (1) adding polyoxyethylene monolaurate, sodium pyrophosphate, calcium carbonate, benzoyl peroxide, kaolin, deionized water, ammonium peroxydisulfate, butyl methacrylate, maleic anhydride, potassium persulfate, laurinol and methyltriethoxysilane in a reaction kettle, heating to 58 DEG C, and reacting for 65 minutes by stirring; (2) adding benzoyl peroxide, butyl methacrylate, potassium persulfate, maleic anhydride, deionized water and ammonium peroxydisulfate in the reaction kettle, heating to 75 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 48 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 preparation process is good in stability.
Description
Technical field
The present invention relates to the preparation technology of high stability anti-dripping agent.
