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 [0001] The invention relates to the field of manufacturing chemical polymer materials, in particular to a method for preparing PTFE / PPS micropowder for non-stick pan coatings. Background technique [0002] Polytetrafluoroethylene in non-stick pan coatings has a stable C-F bond because the carbon chain in the molecule is surrounded by highly electronegative fluorine atoms, making it excellent in heat resistance and extremely inert on the surface. Almost all viscous substances are It cannot be adhered to its surface, nor can it be bonded by ordinary methods. Different from PTFE micropowder for general additives, PTFE raw materials for non-stick pans must contain certain bonding components, and its main function is to make PTFE adhere to the substrate effectively. Only in this way can the various properties of the non-stick coating be strengthened, so that the performance of PTFE non-stick pan coating can be fully exerted. In the prior art, roughening and othe...
