Description
Technical field
The present invention relates to a kind of material of making bearing inner-core, specifically a kind of special-purpose material of engineering plastic bearing inner core.
Background technology
Plastic bearing is unique in light weight, and simple installation is corrosion-resistant, avoids safeguarding, has the vibration shock isolation that cast iron seat commonly used or punching press seat do not had simultaneously and hits performance.Along with continually developing just more and more of novel material is used widely on engineering.
Traditional plastic bearing inner core adopts PE (polyethylene), and HDPE (high density polyethylene(HDPE)) can satisfy general applications.The flat plastic bearing that automobile is used requires under high-load condition, realizes ultra-low friction coefficient and low abrasive wear, and traditional PE and HDPE can not meet the demands, and needs could realize with ultrahigh molecular weight polyethylene(UHMWPE).Ultrahigh molecular weight polyethylene(UHMWPE) can satisfy working conditions, but ultrahigh molecular weight polyethylene(UHMWPE) is processed not easy-formation, and traditional Shooting Technique can't realize that common medium and small manufacturing enterprise is difficult to produce.
Summary of the invention
The object of the present invention is to provide a kind of special-purpose material of engineering plastic bearing inner core, during part that the requirements such as flat plastic bearing that utilize this material produce automobile to use are worked under high-load condition, can reduce frictional coefficient and reduce wear.
According to technical scheme provided by the invention, it is 35～55 ultrahigh molecular weight polyethylene(UHMWPE) that described special-purpose material of engineering plastic bearing inner core contains weight part, weight part is 30～40 parts a high density polyethylene(HDPE), weight part is 5～20 parts a comprehensive lubricant, weight part is 5～8 superfine silicon dioxide, weight part is 1～5 silane coupling agent, weight part is 0.5～3.5 organotin, weight part is 0.4～0.6 dispersion agent, and weight part is that 0.1～0.4 antioxidant 1010 and weight part are 0.1～0.4 oxidation inhibitor 168.
Described comprehensive lubricant is the mixture of ptfe micropowder and organic silicone oil, and wherein the amount of organic silicone oil is 0.5～2 weight part, and the amount of ptfe micropowder is 98～99.5 parts.
Also add the auxiliary material of 0.5～1 weight part at described comprehensive lubricant, described auxiliary material is silicone powder, silicone compounds, Zinic stearas, MoS
2In the combination of any one or a few material.
Traditional PE and HDPE have good processing properties, but can't satisfy low-friction coefficient and the low frictional dissipation of automotive plastic bearing under high-load condition; Ultrahigh molecular weight polyethylene(UHMWPE) can satisfy low-friction coefficient and the low frictional dissipation of automotive plastic bearing under high-load condition, and but processing difficulties can't be implemented on the common injection moulding machine and produce.In order to overcome this contradiction, the invention provides a kind of special-purpose material of engineering plastic bearing inner core, by in HDPE and ultrahigh molecular weight polyethylene(UHMWPE) mixed plastic, adding comprehensive lubricant, can effectively reduce the frictional coefficient under the material high-load condition; Add the vulcanization crosslinking auxiliary agent, realize that its frictional dissipation is lowered in the cross-linking vulcanized back of material.
The invention has the beneficial effects as follows: 1,, guaranteed the low friction of material and the performance of low frictional dissipation owing to contain the comprehensive lubricant that 35～50 ultrahigh molecular weight polyethylene(UHMWPE) and weight part are 10～20 parts in this material component; Contain simultaneously weight part again and be 30～40 parts high density polyethylene(HDPE), guaranteed the injection moulding performance of material.2, because to contain weight part in this material be 1～5 silane coupling agent, weight part is 0.5～3.5 organotin, as crosslinked and vulcanization aid, the consistency of ultrahigh molecular weight polyethylene(UHMWPE) in the material of assurance and high density polyethylene(HDPE) and comprehensive lubricant keeps the material component homogeneity.3, because to contain weight part in this material be 5～8 superfine silicon dioxide, improved the heat-drawn wire of material monolithic, physical strength guarantees under the condition that runs up, and can not be out of shape because temperature raises; , improved the physical strength of material monolithic, guaranteeing under high-load condition not can be by the pressure distortion of collapsing.4, weight part is the dissemination that 0.4～0.6 dispersion agent mainly plays each constituent materials in this material.Weight part is that oxidation inhibitor 168 that 0.1～0.4 antioxidant 1010 and weight part are 0.10.1～0.4 acts on and prevents the macromolecular material oxidative degradation in the process of manufacture.
