It is high.
The raw material of nylon 46 and different ratio is used cooperatively by sliding bearing of the present invention with composite material, explores each raw material
Influence to bearing friction coefficient and abrasion loss, by the cooperation between each raw material, it is particularly viscous to solve nylon 46, and when rolling is viscous
Roller leads to not the problem normally produced.Wherein, Nano titanium nitride does crystallization nucleating agent use, by way of polymerization
It is scattered in it preferably in nylon 46 engineering plastics, the crystalline rate of nylon 46 can be greatly speeded up, if not adding nitridation
Titanium bear compared with energetically in the case where abrasion loss it is larger.Fanglun slurry cake can increase the binding force between each material, be changed with enhancing
The plastic deformation of property nylon 46；If common polytetrafluoroethylene (PTFE), glass fibre, graphite these types material are added, by larger
Abrasion loss is larger when power, is unfavorable for the service life of bushing；And the additive amount of magnesium carbonate, graphite is excessive or too small can all lead to bearing
Abrasion loss becomes larger.

The ratio of each raw material of 1 surface composite layer of table
In order to sufficiently verify the performance of sliding bearing composite material of the present invention, will be said below by testing result
It is bright, and probe into the influence of raw material type and dosage to bearing performance.
1, friction-wear test:
After finished sleeve plate is made, according to Q/YH-3 (PA46) type composite material sliding shaft sleeve technical conditions (tentative)
5.4 requirement load 24.5MPa, 180 minutes time carry out friction-wear test using the method for grease lubrication.

Data can see from table 2, and axle sleeve plate wear-resisting property of the present invention is excellent.
The influence of 3 raw material type of table and dosage to axle sleeve plate property
It can be seen from the data in Table 3 that adding the coefficient of friction for matching comparison material and the abrasion of different raw material and raw material
Amount has direct influence.Since nylon 46 is particularly viscous, and roll banding when rolling, it can not normally be produced, if addition is normal
Polytetrafluoroethylene (PTFE), glass fibre, graphite these types material, when by more energetically, its abrasion loss is again bigger, is unfavorable for
The service life of bushing.If in the case that glass fibre is changed to Fanglun slurry cake, material abrasion loss is just obviously reduced.Single addition carbonic acid
When magnesium, its ratio 3% be it is best, 5% cannot be greater than, otherwise abrasion loss becomes larger；With polytetrafluoroethylene (PTFE), Fanglun slurry cake, nanometer
It is big when the abrasion loss of 3% magnesium carbonate is than addition 1% after titanium nitride mixing.It is poly- with addition 5% when graphite addition 3%
The Fanglun slurry cake of tetrafluoroethene and addition 5% is big when its abrasion loss is than addition 1%.If not adding titanium nitride bearing
Abrasion loss is also bigger in the case where more energetically.Finally obtained by repetition test the raw materials used in the present invention no matter it is larger and compared with
In the case where small power, abrasion loss is all the smallest.
2, bonding strength test
Axle sleeve plate obtained by embodiment 1-4 needs that 120mm × 20mm × plate is made referring to GB/T 27553.2-2011
The sample of actual (real) thickness clamps on special fixture shown in Fig. 2, and sample is then pressed 60 ° of angular distortions towards plastics direction first,
