Description
Technical Field

Background
The traditional self-lubricating bearing is made of laminated sintered composite plates, such as composite plates of steel-copper powder or woven copper mesh-nonmetal materials, and the general manufacturing process of the composite plates is as follows: cutting a steel plate, spreading copper powder on the surface of the steel plate, sintering, leveling, spreading non-metal antifriction material on the surface, sintering, rolling and leveling by a roller to a plate with a specified thickness to prepare a blank used as a sliding bearing, and forming a part according to requirements, wherein the part is easy to wrinkle or separate from a material joint surface when working at a high temperature due to the inconsistency of the physical properties of steel and non-metal materials, such as different thermal expansion coefficients; during the bending process of the flat plate material, the separation between the joint surfaces of the material can be caused due to the different curvatures of the inner layer and the outer layer of the material. Therefore, in the production process, spherical copper powder is generally paved on the surface of the steel material base and sintered to increase the roughness of the surface of the steel material base and form gaps, so that the adhesion between the non-metal antifriction material and the surface of the steel material base is improved, and the non-metal antifriction material and the steel material base are not easy to separate. The copper powder sintering process is complex, the quality is difficult to control, a large amount of energy is consumed, and certain ecological environment influence exists; in addition, in the traditional manufacturing process, the wear-resistant material is in a powder structure and is manufactured by rolling, the process causes the bearing composite layer to be thin, the load capacity is low, the service life is short, the wear-resistant material can be peeled off and separated from metal or cracked along a flange in the using process, and has higher requirements on the assembly environment,

An organic structural formula:
the method for bonding the composite self-lubricating composite material with high performance, wherein the composite material is prepared by bonding and compounding a metal support, an adhesive layer and a composite sliding layer under pressure and by heating and conduction, comprises the following steps:
the method comprises the following steps of firstly, performing surface treatment on the metal support 100 before using the metal support 100, wherein the surface treatment comprises the following steps: 1. ultrasonic degreasing of the metal plate; 2. pickling with hydrochloric acid; 3. washing with hot water; 4. washing with cold water; 5. passivating trivalent chromium; 6. and (5) cleaning. The adhesive force of the adhesive is larger than that of the surface mechanical structuring process under the same condition of adopting the surface upgrading process;
step two, preparation of the adhesive layer 110, 1, mixing and extruding the mixture by using a screw-driven extruder to form the adhesive layer 110. 2. And (3) compounding: continuously compounding at high speed by a twin-screw compounder to be uniformly mixed together.
After the polymers are proportioned according to the proportion, the polymers are added and continuously compounded for not less than 25 minutes at a high speed by a double-screw compounding machine so as to be uniformly mixed together; and then compounded and extruded using a twin screw driven extruder to form the adhesive layer 110.
The prepared adhesive is subjected to plasma cleaning, so that the polar components of the adhesive are increased, and the adhesive force is obviously improved;
step three, surface pretreatment of the composite sliding layer 120, because of the extremely low surface energy of the composite sliding layer 120, the adhesive layer 110 can have enough bonding strength with the metal support 100, but the bonding strength with the composite sliding layer 120 is far from meeting the requirement, and particularly, when the composite sliding layer is processed into a bearing, the adhesive layer 110 and the composite sliding layer 120 must keep higher bonding strength in the face of a complex working condition environment; therefore, the surface of the composite sliding layer 120 is pretreated, and the surface pretreatment of the composite sliding layer 120 comprises the following methods:
first, high temperature melting method
The basic principle of the method is that the crystal form of the surface of the composite sliding layer 120 is changed at high temperature to embed some substances with high surface energy and easy adhesion, such as SiO2, AL powder, etc., and after cooling, a modified layer embedded with adhesive substances is formed on the surface of the composite sliding layer 120, and the molecules of the easy adhesion substances enter the molecules of the surface layer of the composite sliding layer 120 to damage, which is equivalent to intermolecular damage, so that the bonding strength is high.
Method II, radiation grafting method
The method needs a Co-60 radioactive source to place the composite sliding layer 120 film in polymerizable monomers such as styrene, fumaric acid, methacrylate and the like, and chemical graft polymerization is carried out on the monomers on the surface of the PTFE film by Co-60 radiation, so that a layer of graft polymer easy to bond is formed on the surface of the PTFE film.
Method III, chemical treatment of sodium-naphthalene complex
The fluorine-containing material is chemically treated by reacting the corrosive liquid with the surface of the composite sliding layer 120, thereby tearing off part of the fluorine atoms on the surface and leaving a carbonized layer and some polar groups on the surface.
Method IV, corona plasma method
The plasma treatment is to expose the material to non-polymerizing gas plasma, utilize plasma to bombard the material surface, cause various changes of the polymer material structure to carry on various interactions with active material in the plasma and polymer material surface modification of the polymer material, the plasma treatment polymer surface has different mechanisms, the general way is to put the fluorine-containing material in the glow discharge tube or plasma generator, first pump the system to the vacuum of 1.33Pa, then let in the micro inert gas and adjust the vacuum degree to about 133.32Pa, when the high frequency coil is energized, the activated inert gas and polymer surface act for more than 15 minutes, can produce tough and tough skin layer adhesive strength on the surface and increase from 0.52MPa to 5.2MPa, the contact angle to water is reduced from 111 to 91, several parameters of the plasma treatment such as gas pressure, plasma pressure, The frequency, power, action time and the like of the electric field are easy to adjust, and ideal control can be obtained to generate good effect. If the composite sliding layer 120 is surface-modified at a high electric field/gas density ratio, the surface energy of the modified PTFE is significantly increased as compared to the conventional process.
Method five, ARF laser method
The ARF is used as excimer laser processing, PTFE is a new method adopted abroad at present, the basic principle is that a certain substance is irradiated by a laser to react with the surface of PTFE, and the method can be divided into the following parts according to different reaction types:
(1) carrying out radical reaction;
(2) carrying out grafting reaction;
(3) the improvement of the adhesion property of the polytetrafluoroethylene can also be started from the forming process, and before the polytetrafluoroethylene film is formed, a light absorber is added into the polytetrafluoroethylene film, and the polytetrafluoroethylene film is sintered and then irradiated by ultraviolet laser, so that the wettability can be improved, and the heat resistance and the illumination resistance are greatly improved.
In the present invention, the corona plasma method is preferred, and has the following advantages:
(1) the range of treatment materials is wide, and the treatment materials can be used for polyethylene, polypropylene, polyvinyl chloride, polyamide polyester, polycarbonate, fluoroplastic, various corresponding copolymers and the like;
(2) the treatment time is short, the speed is high, and the treatment can be carried out on a production line;
(3) the operation is simple, and the control is easy;
(4) the corona treatment only relates to the extremely shallow range of the plastic surface layer, generally only has the nanometer order of magnitude, and basically does not influence the mechanical property of the product;
(5) no waste liquid is discharged, and the environment is basically not polluted;
