Description
Technical field
The present invention relates to a kind of chemical industry macromolecular material and manufacture field, particularly the non-stick pan coating preparation method of PTFE/PPS micro mist.
Background technology
Tetrafluoroethylene in non-stick pan coating is surrounded by the fluorine atom that electronegativity is extremely strong due to the carbochain in molecule, define stable C-F key, make its excellent heat resistance, the extreme inertia in surface, nearly all viscous substance all can not stick to its surface, can not bond by usual way.Different from general additive PTFE micro mist, will contain certain bonding component in non-stick pan PTFE raw material, its Main Function is that PTFE is attached on base material effectively.Only in this way could strengthen the various performances of non-sticky metallic coating, the non-stick pan coating property of PTFE is given full play to.In prior art, generally the process such as alligatoring are carried out to base material, promote chemical adhesion by mechanically link, PTFE non-sticky metallic coating is attached on base material.The non-stick pan coating PTFE/PPS micro mist that this method obtains can produce harmful, the product of contaminate environment.
Summary of the invention
The object of the invention is to provide a kind of safety, environmental protection, pollution-free, preparation method to human body inert non-stick pan coating PTFE/PPS micro mist to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the preparation method of PTFE/PPS micro mist of the non-stick pan coating designed by the present invention, concrete steps are as follows:
A), tetrafluoroethylene and polyphenylene sulfide raw material are carried out radiation with radioactive rays in radiation environment;
B), by the powder after irradiation carry out comminution by gas stream with micronizer mill at normal temperatures, regulate the size classification device of micronizer mill to obtain tetrafluoroethylene and polyphenylene sulfide micro mist;
C), the tetrafluoroethylene obtained is mixed with polyphenylene sulfide micro mist and auxiliary agent.
Above-mentioned steps c) in auxiliary agent be inorganic nanometer powder, and tetrafluoroethylene: polyphenylene sulfide: mass ratio=1 of inorganic nanometer powder: 0.1 ~ 0.4: 0.1 ~ 0.3.Described inorganic nanometer powder can be nanometer zirconium phosphate, and median size is less than 150 nanometers.
The preparation method of described non-stick pan coating PTFE/PPS micro mist, is characterized in that described PTFE and PPS mass ratio is adjustable.Step a) in radiation environment be air or rare gas element, radioactive rays are r ray or electron beam, and this gamma ray source is 60Co or 137Cs, and the radiation dose of radioactive rays is at more than 80KGy.Step b) in the pressure of micronizer mill be 800KPa ~ 1200KPa, the particle diameter of non-stick pan coating PTFE/PPS micro mist prepared by micronizer mill is less than 2 μm.Step c) in auxiliary agent be inorganic nanometer powder, and tetrafluoroethylene: polyphenylene sulfide: mass ratio=1 of inorganic nanometer powder: 0.1 ~ 0.4: 0.1 ~ 0.3.
The preparation method of the non-stick pan coating PTFE/PPS micro mist that the present invention obtains, the non-stick pan coating PTFE/PPS micro mist of production has not viscosity, province's oiliness, and to the nothing harm performance of human body, and production efficiency is high.
