Compared with the prior art, the environmentally-friendly plastic thrust bearing bush and the production method provided by the invention have the advantages of short molding cycle, outstanding environmental performance, uniform elastic modulus and the like.
Description
Technical field
The present invention relates to a kind of thrust bearing shoe and preparation method thereof, especially relate to a kind of environmentally-friendly plastic thrust bearing shoe and preparation method thereof.
Background technique
Traditional elastic metal-plastic thrust bearing bush is primarily of 3, steel tile base, elasitic layer and polytetrafluoroethylplastic plastic layer part composition, mainly contain 2 kinds of preparation methods at present, a kind of is be sprinkling upon by molding powder uniform spreading in the elasitic layer space of spring composition, shaping under pressure, again after high temperature sintering, with leypewter, itself and steel tile base are carried out soldering; Another kind is that elasitic layer and polytetrafluoroethylplastic plastic layer manufacture separately, elasitic layer with plastic layer compound after need to carry out the process of immersed solder material, subsequently composite bed and steel tile base are carried out soldering, and solder is generally leypewter liquid.Therefore, all use heavy metal lead in these two kinds of processing method processes, and under the high temperature conditions, leypewter steam can be produced, simultaneously plumbous containing plurality of heavy metal in its obtained product.As everyone knows, heavy metal lead can impact environment and health, does not meet the requirement of society to environmental protection.
Summary of the invention
Object of the present invention is exactly the plumbous pollution on the environment in order to solve in traditional elastic metal-plastic thrust bearing bush, provides a kind of novel environment friendly plastics thrust bearing shoe and preparation method thereof.
Object of the present invention can be achieved through the following technical solutions:
A kind of environmentally-friendly plastic thrust bearing shoe, comprise steel tile base and surface plastic materials layer, this surface plastic materials layer is directly bonded on steel tile base through solventless adhesive, forms thrust bearing shoe, do not need to arrange spring pad between steel tile base and surface plastic materials layer, do not need to carry out brazing yet.
The raw material that described surface plastic materials layer adopts following component and done percentage composition prepares:
The mixture 0 ~ 10% of the mixture 0 ~ 30% of polyether-ether-ketone 60% ~ 100%, carbon fiber and glass fibre, graphite and molybdenum disulfide.
As preferred embodiment, surface plastic materials layer adopts the raw material of following component and weight percent content to prepare:
The mixture 3% of the mixture 17% of polyether-ether-ketone 80%, carbon fiber and glass fibre, graphite and molybdenum disulfide.
Described polyether-ether-ketone is commercially available polyether-ether-ketone resin.
Described carbon fiber is ground carbon fiber, and glass fibre is milled glass fiber, fiber diameter 5 ~ 30 μm, slenderness ratio 5:1 ~ 10:1.
Described graphite is aquadag, particle diameter≤2 μm, and described molybdenum disulfide is colloid molybdenum disulfide, particle diameter≤1.5 μm.
Described solventless adhesive is epoxyn or polyurethane resin adhesive.
The making method of environmentally-friendly plastic thrust bearing shoe, adopts following steps:
(1) by formula mixed material, utilize mechanical agitation that uniform filling is distributed, and the material mixed is put into mould, hotpress is hot pressed into sheet material;
(2) solventless adhesive is prepared;
(3) solventless adhesive is coated in uniformly on the steel tile base crossed by solvent clean and shaping sheet material;
(4) control temperature and pressure bonding steel tile base and shaping sheet material;
(5) with surface grinding machine, bonding environmentally-friendly plastic thrust bearing shoe blank is machined to required size, namely makes and obtain environmentally-friendly plastic thrust bearing shoe.
In step (1), the temperature of hot pressing is 360 ~ 380 DEG C, and pressure is 10 ~ 30MPa, is incubated 1.5 ~ 3h during thermoforming.
In step (4), control temperature is 80 ~ 120 DEG C, and pressure is 1 ~ 3MPa, insulation 2 ~ 3h.
Compared with prior art, the elastic metal-plastic thrust bearing manufactured by the present invention does not need to arrange spring pad, does not need to carry out brazing yet.Former spring pad mainly provides the intensity of elastic metal-plastics bearing top layer plastics, elasticity and dimensional stability in whole thrust-bearing system, polyether-ether-ketone sheet material is adopted to exceed a lot as itself intensity of surface layer, Young's modulus all more original top layer plastics teflon, and its dimensional stability is high, the intensity needed for thrust-bearing, elasticity and dimensional stability can be provided.In addition, the present invention also has the following advantages:
1, molding cycle is fast.Its molding cycle of conventional fabrication techniques is substantially at about 20 days, it is more that the establishment of its spring takies man-hour, and the quality of spring arrangement is related to the uniformity of plastic thrust bearing bush surface elastic modulus, what traditional thrust bearing shoe adopted simultaneously is that teflon is as top layer plastics, its sintering time comparatively polyether-ether-ketone plate forming time length is a lot, and the plastic thrust bearing bush prepared by the present invention eliminates spring establishment and immersed solder material treating process, molding cycle can be increased to 10 days;
2, environmental-protecting performance is given prominence to.Conventional fabrication techniques uses heavy metal lead in a large number in the process of immersed solder material, soldering operation, and is all in high temperature environments, and this not only impacts the healthy of production operation workman, and can pollute ambient atmosphere, soil.The technology used in the present invention all round process heavy metal free is plumbous, bonding used be solventless adhesive, can not impact human body and environment;
3, Young's modulus is even.No matter traditional elastic metal-plastic thrust bearing bush leaching solder process is in atmospheric conditions or under vacuum, gap between spring layer all can not be completely filled in, portion gap can be left, the randomness of its interstitial site causes top layer Young's modulus and may occur uneven phenomenon, the present invention adopts modified polyetheretherketonefiber sheet material to be directly bonded on steel tile base, can effectively avoid this problem.
