Abstract

The invention discloses a sterilization and deodorization carbon fiber and steel fiber modified polytetrafluoroethylene material and a method for preparing the same. The sterilization and deodorization carbon fiber and steel fiber modified polytetrafluoroethylene material and the method have the advantages that the tensile strength and the friction performance of polytetrafluoroethylene can be improved by steel fibers and carbon fibers; fine fillers such as SiO2 and Al powder are sintered on the surfaces of the polytetrafluoroethylene by the aid of improved melting processes at the high temperatures, accordingly, surface sintered states of the polytetrafluoroethylene can be improved, and the bonding strength can be obviously enhanced; surrounding environments can be sterilized owing to characteristics of high adsorption capacity of diatomaceous earth, the humidity can be regulated, and deodorization effects and the like can be realized by the sterilization and deodorization carbon fiber and steel fiber modified polytetrafluoroethylene material.

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 carbon fiber and steel fiber modified polytetrafluoroethylene material for sterilization and deodorization 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 ...
