Abstract
A PTFE composite TPU solvent resistance conveying belt comprises boned fabric and a TPU surface layer; a PTE thin film is composited on a TPU conveying belt surface layer, and the PTFE composite TPU solvent resistance conveying belt is obtained. A manufacturing method for the solvent resistance conveying belt comprises the steps that a single face of the PTE thin film is treated through a sodium naphthalene solvent, and the sodium treatment PTFE film is obtained, so that the PTFE film and the TPU conveying belt surface layer have stickiness, and a finished product is obtained through compositing. By the adoption of the PTFE/TPU composite surface layer, the solvent resistance of the conveying belt surface layer is improved; the sodium treatment PTFE film and the TPU conveying belt surface layer are composited, certain sticking force exists between the PTFE film and the TPU conveying belt surface layer, and layering is not prone to happening.
Description
Technical field
The present invention relates to the manufacturing technology field of load-transfer device, especially a kind of PTFE compound TPU solvent resistant load-transfer device and manufacture method thereof.
Background technology
TPU light-type conveyer belt is generally framework material with polyester textile, mainly for delivery of light, middle quality material.TPU light-type conveyer belt is lightweight with it, the life-span long, easy for installation, not easily produce the advantage such as friction, be widely used in the industries such as logistics, airport, postal service, entertainment body-building.
TPU light-type conveyer belt due to Facing material be TPUE (TPU), it is a kind of thermoplastic material, therefore be poor-performing in solvent, various organic solvent all can cause corrosion to it, use under the environment of organic solvent for a long time, belt body surface cracking, aging, layering can be caused, larger impact is caused on the use of load-transfer device.
Polytetrafluoroethylene (Polytetrafluoroethylene) is a kind of synthesized polymer material employing fluorine and replace all hydrogen atoms in polyethylene.This material structure is stablized, and has the feature of antiacid alkali resistant, anti-various organic solvent, is dissolved in all solvents hardly.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of solvent-proof PTFE compound TPU solvent resistant load-transfer device.
Another object of the present invention is to provide the manufacture method of above-mentioned PTFE compound TPU solvent resistant load-transfer device.
The object of the invention is achieved through the following technical solutions: a kind of PTFE compound TPU solvent resistant load-transfer device, comprises skeleton fabric, TPU surface layer, and compound one deck PTFE film on TPU load-transfer device surface layer, obtains PTFE compound TPU solvent resistant load-transfer device.Significantly improve the solvent resistance of load-transfer device, extend the service life of load-transfer device.
Because PTFE surface energy is lower, quite difficult with the bonding of other materials, for this reason, the invention provides a kind of manufacture method of PTFE compound TPU solvent resistant load-transfer device, step is: first process PTFE film one side naphthalene sodium solvent, obtain sodium PTFE film, make to produce viscosity between PTFE film and TPU load-transfer device surface layer, obtain finished product by compound.
Need first to carry out sodium process to PTFE film before compound, use naphthalene sodium solvent to process PTFE film one side, the part fluorine atom on its surface is replaced by other polar groups, makes to produce viscosity between PTFE film and TPU load-transfer device surface layer, obtain finished product by compound.
On such scheme basis, production procedure is sequentially: fabric sizing, the primary coat of fabric face glue, the primary coat of envers glue, calendering TPU layer obtain TPU load-transfer device, and then, compound sodium PTFE film obtains finished product.
Concrete steps are:
The first step, polyester textile carries out drying and qualitative through Far-infrared Heating, and baking temperature is at 180 ~ 200 DEG C;
Second step: the primary coat of fabric face PU glue, baking temperature 150 DEG C;
3rd step: the primary coat of envers PU glue, baking temperature 150 DEG C;
