Abstract

The invention discloses a fluorescent polytetrafluoroethylene material modified with carbon fibers and steel fibers and a preparing method of the fluorescent polytetrafluoroethylene material. The fluorescent polytetrafluoroethylene material modified with carbon fibers and steel fibers and the preparing method of the fluorescent polytetrafluoroethylene material are characterized in that steel fibers and carbon fibers are used for improving the tensile strength and the friction performance of polytetrafluoroethylene; meanwhile, an improved melting method is used for sintering fine filler such as SiO2 powder and Al powder to the surface of polytetrafluoroethylene at a high temperature, the surface sintered state of polytetrafluoroethylene is improved, and the joint strength is obviously improved. Besides, fluorescent powder is added in a matched mode, and the material can absorb energy after being illuminated by light and can automatically emit light in dark places.

Description

technical field [0001] The invention relates to the fields of carbon fiber and steel fiber surface modification and polytetrafluoroethylene modified materials, in particular to a fluorescent carbon fiber and steel fiber modified polytetrafluoroethylene material and a preparation method thereof. Background technique [0002] Polytetrafluoroethylene (PTFE) is resistant to high and low temperatures, chemical corrosion, no water absorption, low coefficient of friction, excellent dielectric properties, known as the "King of Plastics". But because of the low surface energy (surface tension is (31 ~ 34) ×10 -3 N / m), high crystallinity and molecular chain structure symmetry and non-polarity, making it difficult to be bonded, restricting its application in the field of valve sealing materials. For this reason, scientists have adopted various methods to try to solve the surface bonding problem of PTFE, among which there are many studies on changing the surface structure or properties ...
