The invention relates to a method for improving the temperature resistance of a fluorine polymer. In the method, white filaments of which the diameters are between 1 and 2 microns are added appropriately in a preparation process so that the temperature resistance is improved, the range of application is expanded and using temperature grade is lifted.
Description
technical field [0001] The invention relates to a measure for enhancing the temperature resistance of fluoropolymers. Background technique [0002] Perfluoropolymer is a kind of electrical insulation material with high temperature resistance and chemical corrosion resistance, which is widely used in defense industry and civilian industry, but it is prone to cold flow and cracking, which affects the wide use of this material. Contents of the invention [0003] In the invention, when the perfluoropolymer is made, a kind of fine-diameter filaments are properly added into a polymer with a network structure, so that the temperature resistance is achieved, and the creep performance and cracking resistance are improved. detailed description [0004] When making perfluoropolymers, white filaments with a diameter of 1-2 microns made of fly ash are properly added to transform linear molecules into network-like molecules, which improves the product’s service temperature rating and ...
