Nitrile reclaimed rubber is made of waste nitrile rubber products as raw materials through crushing, desulfurization, rolling and other processes, which retains the basic performance characteristics of nitrile rubber, excellent oil resistance, wear resistance, aging resistance, and has a certain plasticity and viscosity, which can replace nitrile rubber to produce oil-resistant and wear-resistant products, effectively reducing the cost of raw materials. In actual production, what occasions can nitrile reclaimed rubber be used? What problems should I pay attention to during use?
1. Application of nitrile reclaimed rubber in auto parts
Automobile tire lining, engine oil seals and all kinds of gaskets will be exposed to a large amount of oil and wear during the operation of the car, nitrile reclaimed rubber has excellent oil resistance and wear resistance, can effectively resist oil erosion and mechanical wear, prolong the service life of parts, is an ideal material for the production of auto parts. When using nitrile reclaimed rubber alone or in combination with nitrile original rubber to produce auto parts, it is necessary to strictly control the molding process conditions, such as temperature, pressure and time, to ensure the dimensional accuracy and physical properties of the finished product and meet the high standard requirements of auto parts.
2. Application of nitrile reclaimed rubber in industrial rubber products
Nitrile reclaimed rubber has good oil resistance, wear resistance, heat resistance and air tightness, and is often used in industrial rubber products such as rubber conveyor belts, seals, and shock absorbing blocks to ensure that rubber products maintain good performance in harsh working environments. For example, the rubber conveyor belt produced by the combination of nitrile rubber/nitrile reclaimed rubber can effectively resist the erosion of chemicals and the friction of heavy objects. When using nitrile reclaimed rubber to produce industrial rubber products, the design of the formula is very important, and it is necessary to reasonably select fillers and additives, such as reinforcing agents, antioxidants, etc., according to the requirements of its working environment for physical properties, so as to achieve the best use effect.
3. Application of nitrile reclaimed rubber in the production of shoe materials
Nitrile reclaimed rubber has excellent oil resistance and good abrasion resistance, and can be used to produce rubber soles, heels, insoles and other parts, especially suitable for making work shoes, labor protection shoes and other footwear that need to be frequently exposed to grease and bear large friction. Adding nitrile reclaimed rubber to the rubber sole can improve the wear resistance and anti-slip performance of the sole; Nitrile reclaimed rubber is used in combination with other materials to prepare the upper material, which can improve the strength and durability of the upper. The rational use of nitrile reclaimed rubber in the processing of shoe materials and the strict control of the vulcanization parameters of rubber compounds can effectively reduce the manufacturing cost of shoe materials and improve the market competitiveness of products on the premise of ensuring the performance indicators of shoe materials.
4. Application of nitrile reclaimed rubber in rubber sheets
Nitrile reclaimed rubber sheet has good elasticity and impact resistance, and is suitable for all kinds of mechanical gaskets, shockproof pads, etc., to meet the different needs of machinery, construction and other fields. When using nitrile reclaimed rubber as the main raw material to produce rubber sheets, the strength and wear resistance of the plates can be improved by appropriately adjusting the variety and dosage of fillers in the formula; Strictly control the mixing and vulcanization process parameters to ensure the uniformity of the quality of nitrile reclaimed rubber sheets.
5. Application of nitrile reclaimed rubber in rubber sealing strips
Nitrile reclaimed rubber has a large oil resistance coefficient, good elasticity, heat resistance and wear resistance, which is an ideal raw material for the production of oil-resistant rubber sealing strips, such as door and window sealing strips, mechanical sealing strips, etc., especially the oil-resistant sealing strips used in oil media for a long time. When using nitrile reclaimed rubber for rubber sealing strips, choose sulfur or peroxide vulcanization system, use carbon black reinforcement, calcium carbonate and talc filling, and use plasticizers to pay attention to the influence of plasticizers on the oil resistance and heat resistance of nitrile reclaimed rubber vulcanized rubber.
6. Application of nitrile reclaimed rubber in rubber gasket and sheath
The rubber gaskets and topics produced with nitrile rubber as the main raw material have good oil resistance and wear resistance, and are widely used in the protection of various machinery and equipment. When using nitrile reclaimed rubber to replace part of nitrile primary rubber to produce rubber gaskets and sheaths, it is necessary to reasonably design the formula, strictly control the vulcanization temperature, E4LYY425 and pressure to ensure that the vulcanization degree and physical properties of rubber products reach the best state, so as to improve the sealing and durability of the gasket; In the production of nitrile rubber sheath, it is recommended to use ultra-fine nitrile reclaimed rubber to better ensure the uniform wall thickness and smooth surface of the sheath, and improve the protective performance and aesthetics of the sheath.
As a typical recycled rubber resource, nitrile reclaimed rubber has low price and excellent oil resistance, wear resistance and aging resistance, and is widely used in auto parts, industrial rubber products, shoe materials, rubber sheets, rubber sealing strips, rubber gaskets and sheaths and other fields, and can be used alone or in combination with nitrile rubber, neoprene, etc., to reduce production costs. In actual production, nitrile reclaimed rubber can also be used for the processing of oil-resistant hoses, cable sheaths, chemical equipment linings, and waterproof materials.
