Abstract
The invention discloses a method for preparing PTFE (polytetrafluoroethylene)/PPS (polyphenylene sulfite) micro power for the coating of the non-stick pan, including the following steps: a) exposing the raw materials of PTFE and PPS to radioactive rays in radiation environment; b) pulverizing the postirradiation powder by jet mill and adjusting the size grading device of the jet mill to produce PTFE and PPS micro powder; c) mixing PTFE and PPS micro powder with the additive. The PTFE/PPS micro powder for the coating of the non-stick pan produced by the method is non-adhesive and oil-saving and does no harm to the human body and is productive.
Description
Technical field
The present invention relates to a kind of chemical industry macromolecular material and make the field, particularly non-stick pan coating is used the PTFE/PPS micropowder preparing process.
Background technology
Tetrafluoroethylene in the non-stick pan coating is owing to the carbochain in the molecule is surrounded by the extremely strong fluorine atom of electronegativity; Formed stable C-F key, made its excellent heat resistance, the extreme inertia in surface; Nearly all viscous substance all can not stick to its surface, can not carry out bonding with usual way.Different with the PTFE micro mist with general additive, non-stick pan is with containing certain bonding component in the PTFE raw material, and it mainly acts on is to make PTFE effectively attached on the base material.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 the prior art, generally base material is carried out processing such as alligatoring, promote chemical adhesion, the PTFE non-sticky metallic coating is attached on the base material through mechanically link.The non-stick pan coating that this method obtains can produce harmful with the PTFE/PPS micro mist, the product of contaminate environment.
Summary of the invention
The objective of the invention is to provide for the deficiency that solves above-mentioned prior art a kind of safety, environmental protection, pollution-free, the inert non-stick pan coating of human body is used the PTFE/PPS micropowder preparing process.
To achieve these goals, the non-stick pan coating that the present invention designed is used the PTFE/PPS micropowder preparing process, and concrete steps are following:
A), tetrafluoroethylene and polyphenylene sulfide raw material are carried out radiation with radioactive rays in radiation environment;
B), the powder behind the irradiation is carried out comminution by gas stream with micronizer mill at normal temperatures, the size classification device of regulating micronizer mill makes tetrafluoroethylene and polyphenylene sulfide micro mist;
C), the tetrafluoroethylene that obtains is mixed with polyphenylene sulfide micro mist and auxiliary agent.
Above-mentioned steps c) auxiliary agent in is an inorganic nanometer powder, and tetrafluoroethylene: polyphenylene sulfide: the mass ratio of inorganic nanometer powder=1: 0.1～0.4: 0.1～0.3.Described inorganic nanometer powder can be the nanometer zirconium phosphate, and median size is less than 150 nanometers.
Described non-stick pan coating is used the PTFE/PPS micropowder preparing process, it is characterized in that said PTFE and PPS mass ratio are adjustable.Radiation environment in the step a) is air or rare gas element, and 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 more than 80KGy.The pressure of the micronizer mill in the step b) is 800KPa～1200KPa, the non-stick pan coating of micronizer mill preparation with the particle diameter of PTFE/PPS micro mist less than 2 μ m.Auxiliary agent in the step c) is an inorganic nanometer powder, and tetrafluoroethylene: polyphenylene sulfide: the mass ratio of inorganic nanometer powder=1: 0.1～0.4: 0.1～0.3.
The non-stick pan coating that the present invention obtains is used the PTFE/PPS micropowder preparing process, and the non-stick pan coating of production has not viscosity, province's oiliness with the PTFE/PPS micro mist, and to the nothing harm performance of human body, and production efficiency is high.
