Abstract
The invention discloses a production method of an anti-dripping agent. The production method comprises the following steps of (1) adding cocoanut fatty acid diethanolamide, N-methylpyrrolidone, benzoyl peroxide, potassium persulfate, calcium carbonate, kaolin, deionized water, ammonium peroxydisulfate, butyl methacrylate, maleic anhydride, triethanolamine and triethoxy ethyl silane into a reaction kettle, heating to 63 DEG C, and reacting while stirring; (2) adding benzoyl peroxide, butyl methacrylate, potassium persulfate, deionized water, maleic anhydride and ammonium peroxydisulfate into the reaction kettle, heating to 75 DEG C, and reacting while stirring; (3) adding a polytetrafluoroethylene dispersing solution and deionized water into the reaction kettle, heating to blend and compound, and adding a flocculant solution at the temperature of 49 DEG C to obtain a sediment; and (4) carrying out centrifugal separation on the sediment, washing, then, carrying out centrifugal separation 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 anti-dripping agent.
Background technology
Existing tetrafluoroethylene anti-dripping agent stability has much room for improvement.
Summary of the invention
The object of the present invention is to provide a kind of production method of anti-dripping agent, its tetrafluoroethylene anti-dripping agent good stability prepared.
For achieving the above object, technical scheme of the present invention designs a kind of production method of anti-dripping agent, comprises the steps:
1) 2 weight part cocoanut fatty acid diethanolamides, 1 weight part N-Methyl pyrrolidone, 4.1 weight part benzoyl peroxides, 3.2 weight part two sulphur eight oxygen acid potassium, 7.5 weight parts of calcium carbonate, 8.6 weight part pavilion soil powder, 44 parts by weight of deionized water, 2.7 acid of weight part peroxo disulfate ammonium, 5.4 weight parts of methacrylic acid butyl esters, 1.8 parts by weight maleic anhydride, 2 weight part trolamines, 1 weight part ethyl triethoxysilanes are dropped in a kettle., be warming up to 63 DEG C, stirring reaction 50 minutes;
2) 3.1 weight part benzoyl peroxides, 18.6 weight parts of methacrylic acid butyl esters, 1.5 weight part two sulphur eight oxygen acid potassium, 17.3 parts by weight of deionized water, 12.4 parts by weight maleic anhydride, 2.8 weight part peroxo disulfate acid ammoniums are dropped into again in a kettle., be warming up to 75 DEG C, stirring reaction 55 minutes;
3) drop into 11.4 weight part polytetrafluoroethyldispersion dispersions, 28.6 parts by weight of deionized water more in a kettle., composite is carried out in heating, adds coagulant solution, be precipitated at 49 DEG C;
4) centrifugation is carried out to precipitation, washing, then centrifugation, dry and pulverize, obtain anti-dripping agent.
Advantage of the present invention and beneficial effect are: the production method providing a kind of anti-dripping agent, its tetrafluoroethylene anti-dripping agent good stability prepared.
