Abstract

The invention discloses an antibacterial polytetrafluoroethylene composite material and a preparation method thereof. The antibacterial polytetrafluoroethylene composite material is characterized in that the tensile strength and friction performance of polytetrafluoroethylene are improved by using steel fibers and carbon fibers, fine packing such as SiO2 and Al powder are sintered on the surface of the polytetrafluoroethylene at the high temperature by utilizing an improved melting method, a surface sintering state of the polytetrafluoroethylene is improved, and the bonding strength is obviously improved. In addition, silver zeolite is further added, so that the composite material has antibacterial and mildew-proof functions.

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 an antibacterial polytetrafluoroethylene composite 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 of PTFE. The main ones ar...
