The weight percent respectively formed is as follows: nylon resin 69.5%~95%, toughener 2%~9%, anti-wear agent 0.5%~20%,
Processing aid 1%~2%, the sum of above-mentioned proportion respectively formed are 100%；The toughener is maleic anhydride grafted polymer,
The anti-wear agent is molybdenum disulfide or ptfe micropowder.The patent solve wear resistant nylon under cold conditions normally make
Use problem.
Chinese patent application CN106995608A discloses a kind of low abrasion nylon 66 composition of high temperature resistant and its preparation side
The mass percent of method, composition and each component is as follows: nylon66 fiber 40~80%；Glass fibre 10~45%；Molybdenum disulfide
0.5~5.0%；Graphene 0.2~5.0%；Heat-resistant agent 0.5~5.0%；Antioxidant 0.2~1.0%；Lubricant 0.1~
5.0%.The low abrasion nylon 66 composition of the high temperature resistant that the patent is prepared has high barrier to hot oxygen, steam, intermolecular
There is mantoquita complexing to prevent nylon66 fiber dehydrogenation, dehydration, can be used in 180 DEG C or less high temperature for a long time, and maintain low-friction coefficient
With low abrasion loss.
It is above-mentioned in the prior art, a series of modifications have been made to nylon66 fiber, have improved nylon material to a certain extent
Wearability, thermal stability and mechanical performance.But when above-mentioned nylon material is in textile equipment, to nylon material
Performance requirement will be higher, and current material is still unable to satisfy demand.
Summary of the invention
In view of the deficiencies of the prior art, that the object of the present invention is to provide a kind of wear-resisting properties is good, thermal stability is high, mechanical strong
The low modified abrasion resistant nylon of height, long service life, production cost is spent, which is mainly used for the oil-free of textile machinery
On bearing holder (housing, cover).
The technical proposal for solving the technical problem of the invention is: a kind of modified abrasion resistant nylon, the modified abrasion resistant Buddhist nun
Dragon mainly by nylon66 fiber, glass fibre, molybdenum disulfide, polytetrafluoroethylene (PTFE), silicone, antioxidant are blended, squeeze out, it is cooling, be granulated
It forms；The content of each component, by weight percentage are as follows:
Further, the content of each component, by weight percentage are as follows:
Further, the content of each component, by weight percentage are as follows:
Preferably, the antioxidant is antioxidant 1098, antioxidant 727.
The preparation method of above-mentioned modified abrasion resistant nylon, the preparation method mainly comprise the steps that
1) desired amount of nylon66 fiber is first dried, is then handled with silane coupling agent；
2) nylon66 fiber handled well is blended with molybdenum disulfide, polytetrafluoroethylene (PTFE), silicone, antioxidant by high-speed stirred,
Mixing speed is 400~600r/min, and premix is made；
3) above-mentioned steps 2 are added in the main feed mouth of extruder) in the premix for preparing, heating temperature is in extruder
250~280 DEG C, in heating process, glass fibre is added in the side feed inlet of extruder, glass fibre squeezes together with premix
Out, cold cut, pelletizing molding, obtain product.
Further, in the step 1), nylon66 fiber is surface-treated using silane coupling agent 560, and the silane is even
