Description

Technical Field

[0001] The invention relates to the technical field of automobile control, in particular to a method for preparing a durable rubber bushing. Background Art

[0002] Automobile rubber bearing sleeve is a bearing combination made of polymer materials such as rubber or synthetic rubber. It is mainly used for speed reduction, shockproof and other sealing functions between reduction gears and sleeves. Rubber sleeves can absorb and damp the vibration between bearings and other components, reduce small noises, provide good dustproof sealing effect, and prevent external dust from entering. Rubber materials have certain elasticity and can withstand certain axial displacement. The rubber material of rubber sleeves can provide certain friction and play a role in deceleration. Rubber bearing sleeves can reduce wear and extend the service life of bearings to a certain extent. Based on the above characteristics, rubber sleeves are mainly used in motor steering, drive shafts, guide wheels and other application scenarios that require shock absorption, deceleration and sealing. However, traditional rubber sleeves have short service life and are prone to aging, cracking, hardening and other problems. They need to be replaced frequently, which increases maintenance costs. Therefore, the research and development of a durable rubber sleeve is a hot issue in the industry.

[0003] At present, some researchers have proposed to improve the durability of rubber tire sleeves by modifying the batching method of rubber materials. However, this method has a defect, that is, changing the batching will affect the physical properties of the rubber material, resulting in unstable quality and performance. Therefore, a new manufacturing method is needed to improve the durability of the layer rubber bearing sleeve while maintaining the physical properties of the rubber material. Summary of the invention

[0004] The present invention aims at the deficiencies in the background technology and provides a method for preparing a durable rubber bushing.

[0005] In order to solve the above-mentioned problem, the present invention adopts the following technical scheme, a method for preparing a durable rubber bushing, and the method steps include the following:

[0006] S1, Improved rubber: When selecting rubber materials, the application scenarios and requirements of the actual hardware need to be considered to determine the most suitable rubber material. Elasticity, wear resistance, chemical stability, heat resistance, high temperature resistance, oil resistance and corrosion resistance need to be considered. When selecting rubber materials, various factors need to be considered according to specific needs, and materials suitable for the actual finished product size and application requirements should be selected;

[0007] S2, raw material mixing processing: adding the selected improved rubber material to a mixer, adding a suitable amount of vulcanizing agent, activating agent, etc., and mixing. The vulcanizing agent and activating agent added to the mixer are key factors, which can sufficiently promote the vulcanization reaction of the rubber material, thereby realizing the crosslinking and curing of the rubber material. The vulcanizing agent needs to be a commonly used vulcanizing agent such as hydrogen sulfide, hydrogen oxide, hydrogen sulfide salt, etc., and the activating agent needs to be a chemical substance that promotes the vulcanization reaction, such as sulfide, sulfide acid salt, dithiol, etc.;

[0008] S3, extrusion molding: put the mixed rubber material into the extruder for extrusion molding. The extruder is responsible for molding the mixed rubber material. The extruder usually consists of two rotating shafts, one of which has raised teeth and the other has grooves. The two shafts move in opposite directions and contact the rubber to extrude the required shape;

[0009] S4, vulcanization treatment: put the extruded rubber shaft into a vulcanization box for vulcanization treatment. The vulcanization box is a device used to vulcanize the rubber sleeve. The purpose of vulcanization treatment is to heat the rubber material under a certain temperature, pressure and time to produce a cross-linking reaction, thereby increasing the strength and temperature of the rubber material and improving its durability and heat resistance;

[0010] S5, special corresponding treatment: The vulcanized rubber sleeve is subjected to special corresponding treatment, which can be surface treatment, coating treatment, filling treatment and other methods to improve the durability of the rubber sleeve.

[0011] As a further preferred embodiment of the present invention, in step S1, natural rubber has good elasticity and wear resistance, but is highly sensitive to temperature, light, grease, etc., and is suitable for low temperature environments and occasions with low friction and wear. Synthetic rubber has good chemical stability and heat resistance, and is suitable for high temperature environments and occasions with strong chemical corrosion. Modified rubber provides specific properties such as high temperature resistance and oil resistance by changing the structure or adding other substances on the basis of natural rubber and synthetic rubber. Therefore, improved rubber is required to achieve various performance requirements.

[0012] As a further preferred embodiment of the present invention, in step S2, the process parameters of the mixer such as temperature, time, rotation speed, etc. also need to be adjusted according to the specific situation to ensure the quality and performance of the rubber material. When it is necessary to modify a certain ability of the rubber material, such as improving anti-aging ability, wear resistance, etc., it is necessary to add a suitable amount of additives during the mixing process.

[0013] As a further preferred embodiment of the present invention, in step S3, during the extrusion molding process, it is necessary to adjust the process parameters of the ejector according to the specific molding requirements, such as the rotation speed of the shaft, the spacing between the shafts, the temperature and pressure, etc. In addition, in order to ensure the quality and molding effect of the product, the extruder needs to be regularly maintained to ensure its normal operation and stable extrusion effect.

[0014] As a further preferred embodiment of the present invention, in step S4, during the vulcanization process, it is necessary to adjust parameters such as vulcanization temperature, pressure and time according to specific rubber materials and molding requirements to ensure the quality and performance of the finished product. At the same time, in order to avoid the adverse effects of gases and steam generated during the vulcanization process on the rubber sleeve, it is also necessary to set a ventilation device and an exhaust system that are composite to the actual production environment in the vulcanization box.

[0015] As a further preferred embodiment of the present invention, in step S5, special treatment is performed to further improve the performance and durability of the rubber bearing sleeve. The specific treatment method is selected according to the use environment and requirements of the rubber bearing sleeve. The surface treatment can be performed by spraying or electroplating to form a protective layer on the surface of the rubber sleeve to improve wear resistance. The coating treatment uses a coating of polymer anti-corrosion materials to improve chemical corrosion resistance. The filling treatment can fill the inside of the rubber sleeve with fiber materials or metal materials to increase the strength and durability of the rubber sleeve. At the same time, a certain proportion of nanomaterials, such as ingot oxide, aluminum oxide, etc., are added to the rubber material to enhance the aging resistance, wear resistance and other properties of the rubber material. Because the nanomaterial has a relatively large specific surface area and special physical and chemical properties, it can form a network structure in the rubber material to increase the strength and stability of the rubber material. In summary, special treatment can be selected according to the use environment and requirements of the rubber sleeve to further improve its performance and durability.

[0016] The present invention provides a method for manufacturing a durable rubber bearing, which can provide high-level rubber bearings with durability and extend their service life while maintaining the physical properties of the rubber compound. The rubber bearing kit manufactured by the method has the following advantages: strong durability. After special treatment, the wear resistance and aging resistance of the rubber material can be greatly improved, so that the rubber bearing equipment has a longer service life. The physical properties are stable. The manufacturing method will not affect the physical properties of the rubber material, so that the rubber bearing kit has more stable quality and performance. The manufacturing process is simple. The process adopted by the manufacturing method is simple and easy to operate, suitable for mass production, and has low production cost. The production method does not require expensive raw materials and equipment, and has low production cost. The durable rubber bearing prepared by the preparation method has a comprehensive improvement with a longer service life and more stable performance, that is, improved durability. It can be widely used in mechanical equipment to provide service life and stable durability for advanced equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1

[0020] The present invention provides a technical solution: a method for preparing a durable rubber bushing, the method steps comprising the following steps:

[0021] The first step is to improve rubber: when selecting rubber materials, it is necessary to consider the application scenarios and requirements of the actual hardware to determine the most suitable rubber material. It is necessary to consider elasticity, wear resistance, chemical stability, heat resistance, high temperature resistance, oil resistance and corrosion resistance. When selecting rubber materials, it is necessary to consider various factors according to specific needs and select materials suitable for the actual finished product size and application requirements; natural rubber has good elasticity and wear resistance, but it is highly sensitive to temperature, light, grease, etc., and is suitable for low temperature environments and occasions with low friction and wear. Synthetic rubber has good chemical stability and heat resistance, and is suitable for high temperature environments and occasions with strong chemical corrosion. Modified rubber provides specific properties such as high temperature resistance and oil resistance by changing the structure or adding other substances on the basis of natural rubber and synthetic rubber. Therefore, improved rubber is needed to achieve multiple performance requirements.

[0022] The second step is raw material mixing and processing: add the selected improved rubber material into the mixer, add appropriate amounts of vulcanizing agent, activating agent, etc., and mix. The vulcanizing agent and activating agent added to the mixer are key factors. They can sufficiently promote the vulcanization reaction of the rubber material, thereby realizing the crosslinking and curing of the rubber material. The vulcanizing agent needs to select commonly used vulcanizing agents such as hydrogen sulfide, hydrogen oxide, hydrogen sulfide salts, etc. The activating agent needs to select chemical substances that promote the vulcanization reaction, such as sulfide, sulfide acid salt, dithiol, etc.; the process parameters of the mixer such as temperature, time, rotation speed, etc. also need to be adjusted according to the specific situation to ensure the quality and performance of the rubber material. When it is necessary to modify a certain ability of the rubber material, such as improving anti-aging ability, wear resistance, etc., it is necessary to add appropriate corresponding amounts of additives during the mixing process.

[0023] The third step is extrusion molding: put the mixed rubber material into the extruder for extrusion molding. The extruder is responsible for molding the mixed rubber material. The extruder usually consists of two rotating shafts, one of which has raised teeth and the other has grooves. The two shafts move in opposite directions and contact the rubber to form the required shape. During the extrusion molding process, it is necessary to adjust the process parameters of the ejector according to the specific molding requirements, such as the rotation speed of the shaft, the spacing of the shafts, the temperature and pressure, etc. In addition, in order to ensure the quality and molding effect of the product, the extruder needs to be regularly maintained to ensure its normal operation and stable extrusion effect.

[0024] The fourth step is vulcanization treatment: put the extruded rubber shaft into a vulcanization box for vulcanization treatment. The vulcanization box is a device used to vulcanize the rubber sleeve. The purpose of vulcanization treatment is to heat the rubber material under a certain temperature, pressure and time to produce a cross-linking reaction, thereby increasing the strength and temperature of the rubber material, and improving its durability and heat resistance. During the vulcanization process, it is necessary to adjust the vulcanization temperature, pressure, time and other parameters according to the specific rubber material and molding requirements to ensure the quality and performance of the finished product. At the same time, in order to avoid the adverse effects of gases and steam generated during the vulcanization process on the rubber sleeve, it is also necessary to set up ventilation devices and exhaust systems in the vulcanization box that are composite of the actual production environment.

[0025] The fifth step is special corresponding treatment: the vulcanized rubber sleeve is subjected to special corresponding treatment, which can be surface treatment, coating treatment, filling treatment and other methods to improve the durability of the rubber sleeve. The special treatment is to further improve the performance and durability of the rubber bearing sleeve. The specific treatment method is selected according to the use environment and requirements of the rubber bearing sleeve. The surface treatment can be sprayed or electroplated to form a protective layer on the surface of the rubber sleeve to improve wear resistance. The coating treatment adopts the coating of polymer anti-corrosion and other materials to improve chemical corrosion resistance. The filling treatment can fill the rubber sleeve with fiber material or metal material to increase the strength and durability of the rubber sleeve. At the same time, a certain proportion of nanomaterials, such as ingot oxide, aluminum oxide, etc., are added to the rubber material to enhance the aging resistance and wear resistance of the rubber material. Because the nanomaterial has a relatively large specific surface area and special physical and chemical properties, it can form a network structure in the rubber material to increase the strength and stability of the rubber material. In summary, the special treatment can be selected according to the use environment and requirements of the rubber sleeve to further improve its performance and durability.

[0026] In summary, the manufacturing method of a durable rubber bearing provided by the present invention can provide high-level rubber bearings with durability and extend their service life while maintaining the physical properties of the rubber compound. The rubber bearing kit manufactured by this method has the following advantages: strong durability. After special treatment, the wear resistance and aging resistance of the rubber material can be greatly improved, so that the rubber bearing equipment has a longer service life. The physical properties are stable. The manufacturing method will not affect the physical properties of the rubber material, so that the rubber bearing kit has more stable quality and performance. The manufacturing process is simple. The process adopted by this manufacturing method is simple and easy to operate. It is suitable for mass production with low production cost. This production method does not require expensive raw materials and equipment, and has low production cost. The durable rubber bearing prepared by this preparation method has a comprehensive improvement with a longer service life and more stable performance, that is, improved durability. It can be widely used in mechanical equipment to provide service life and stable durability for advanced equipment.
