Technical field
The present invention relates to filling-modified thin-film material of a kind of novel nano and preparation method thereof, be specifically related to a kind of nano-ZnO filling-modified PE EK new film material and preparation method thereof, belong to modified PE EK technical field.
Background technology:
PEEK (polyetheretherketone) is the superpolymer that repeating unit constituted that in backbone structure, contains a ketonic bond and two ehter bonds, belongs to the speciality polymer material.Have physical and chemical performances such as high temperature resistant, chemical resistance corrosion; It is one type of crystallization macromolecular material; 334 ℃ of fusing points, 168 ℃ of softening temperatures can be used as high-temperature-resistant structure material and electrically insulating material; PEEK except can with spun glass or the compound preparation strongthener of thomel, can also prepare film forming.The PEEK film has character such as high heat resistance, excellent electric characteristics, particularly chemical proofing, hydrolytic resistance, radiation resistant property, flame retardancy.Even also be quite outstanding in the performance resins film.
The outstanding feature of nano level ZnO is that product pellet is a nano level, has the dual nature of nano material and traditional Z nO simultaneously.Compare with traditional Z nO product, its specific surface area is big, chemically reactive is high, and product fineness, chemical purity and particle shape can be adjusted as required, and has Photochemical effects and cover ultraviolet performance preferably, and its UV-preventing rate is up to 98%; In addition, this special material of nano-ZnO filling-modified PE EK film did not appear in the newspapers so far.
Summary of the invention:
The object of the present invention is to provide a kind of novel material is nano-ZnO filling-modified PE EK film, and a kind of preparation method of technology simple possible is provided.
For realizing above purpose, technical scheme of the present invention provides a kind of preparation method of nano-ZnO filling-modified PE EK film, and starting material are made up of following weight part raw material:
Nano-ZnO 0.1～15%
PEEK virgin resin 85～99.9%
Described nano-ZnO is the Industrial products level, can select the different trades mark for use according to different requirement.
The PEEK virgin resin powder that described PEEK virgin resin is external or the domestic various trades mark, CoPEEK that produces like the Jinlin University spy center of moulding etc.
Technical scheme of the present invention can also provide a kind of preparation method of nano-ZnO filling-modified PE EK film, comprises the steps:
