Description
Technical field
The present invention relates to a kind of thrust washer material compositions and preparation method, belong to technical field of polymer materials.
Background technology
At present, most of thrust washer for using metal, have it is using cast iron, also to use copper, cast iron pad and copper
The features such as not wear-resisting all be present in pad；And copper backing can chemically react with lubricating oil, cause the replacement cycle of lubricating oil
Shorten.So people have focused on the thrust washer of plastics；General high temperature resistant wear-resisting plastics again, such as polyether-ether-ketone and
The special plastic energy work such as polyimides meets the needs of this thrust washer, still, due to the factor of cost；Can not be by high-volume
Use, popularization limited.
As thrust washer, wear-resistant is essential, therefore the material of selection high abrasion is in the selection of material
It is very necessary；This province of common plasticses is athermanous；, can not be by heat derives in high speed rotary grinding, and cause common
Plastics cause the decline and thermal expansion of mechanical strength with the rise of temperature, further cause the mistake of plastics thrust washer
Effect；In addition, the impact being subject in the case of thrust washer in general is all very big.Therefore, material needs very high mechanical strength.
The content of the invention
It is an object of the invention to provide a kind of brand-new high intensity, high abrasion and the thrust washer material of heat conduction and preparation
Method, by material made from the method for adjustment and the preparation of formula, meet the wear-resistant of thrust washer, high intensity and can and
When by heat derives.
The present invention is achieved by the following technical solutions：
The invention provides a kind of thrust washer material compositions, and it includes the following component counted in parts by weight：
Preferably, the polyamide compound includes at least one of PA6, PA66, PA6T, PT9T, PT46.
Preferably, the monofilament number of share of stock of the carbon fiber is 3000~6000 strands.
Preferably, the kollag is in molybdenum disulfide, polytetrafluoroethylene (PTFE), heat curing-type polyimides
It is at least one.
Preferably, the auxiliary agent is one or two kinds of in antioxidant, stabilizer.
A kind of preparation method of thrust washer material compositions as the aforementioned, it comprises the following steps：
Polyamide compound, kollag and auxiliary agent are extruded into plastic melt；
Long carbon fiber is passed through in the plastics in body, coextrusion, through cooling, pelletizing, obtains the thrust washer material
Composition.
Compared with prior art, the present invention has following beneficial effect：
1st, the plastic formula of the mechanical strength higher than common plasticses is obtained, there is very high impact strength and rigidity；
2nd, the length due to carbon fiber and distribution, the material of acquisition have more preferable thermal conductivity；
3rd, the good high-abrasive material that the present invention obtains.
