Abstract

The invention belongs to the technical field of needle felts, and in particular relates to a high performance PTFE coated needle felt and a preparation method thereof, and the high performance PTFE coated needle felt comprises a PTFE mesh base layer, heat insulating cotton layers disposed on both sides of the PTFE mesh base layer, and PTFE coating layers disposed on the heat insulating cotton layers, wherein each PTFE coating layer is provided with a heat dissipating copper plate, the heat dissipating copper plate is interspersed with connecting iron strips, the connecting iron strips pass through the PTFE mesh base layer and the heat insulating copper layers, the heat dissipating copper plate is provided with a magnetic fixing unit for fixing the connecting iron strips by magnetic attraction, and the PTFE coating layers are further provided with heat sink units. The connecting iron strips have high connection strength between the layers of the needle felt, the magnetic fixing unit hasa large fixing strength to the connecting iron strips, the fixing operation and the fixing removal operation of the connecting iron strips are convenient and quick, and the heat dissipation speed ofthe needle felt is fast, and finally the PTFE fiber filtration dust removal ability is improved.

Description

Technical field [0001] The invention belongs to the technical field of needled felt, and particularly relates to a high-performance PTFE coated needled felt and a preparation method thereof. Background technique [0002] PTFE needle felt is a filter material with superior performance. It mainly includes a PTFE mesh base layer and a PTFE fiber coating layer set on it. The two-layer structure can achieve an effective dust filtering and interception effect. On the other hand, the existing PTFE needled felts generally add a high-temperature cotton layer and / or an iron wire reinforcement layer to cope with various filtering practical environments, but the above-mentioned multilayer needled felt structure has insufficient structural strength and is easy to be separated in layers. , And the problem of poor heat dissipation effect, and high temperature use environment will reduce the filtering and dust removal ability of PTFE fiber, so there is an urgent need for a multi-layer structure ...
