The oil-resistant cloth hose is made of rubber as the main body and the cloth as the reinforcing layer, which is mainly used to transport gasoline, kerosene, diesel, lubricating oil, mineral oil and other oil substances at room temperature, including the inner rubber layer, the adhesive cloth layer and the outer rubber layer. In actual production, oil-resistant cloth cloth hoses are mostly processed with oil-resistant nitrile butadiene rubber as the main raw material, and the performance requirements of different adhesive layers are different. However, the price of nitrile rubber is high, and the appropriate use of reclaimed rubber can alleviate the cost pressure of oil-resistant cloth hose manufacturers.
1. The performance requirements of the inner and outer adhesive layers of the oil-resistant cloth hose
The rubber layer in the oil-resistant cloth hose is in direct contact with the conveyed oil medium, which plays a sealing and protective role. The outer layer of the oil-resistant cloth clamping hose is the outer protective layer of the hose, which can prevent damage to the cloth layer by external objects, resist the influence of external chemicals and ultraviolet rays on the hose, and improve the wear resistance and aging resistance of the hose.
2. The oil-resistant cloth hose uses nitrile reclaimed rubber to reduce costs
Nitrile reclaimed rubber is made of waste nitrile rubber products such as nitrile gloves and nitrile bottle stoppers as raw materials, and is processed by crushing, desulfurization, rolling and other processes, which retains the basic performance characteristics of nitrile rubber, excellent oil resistance, good elasticity, wear resistance and aging resistance, etc., and has good compatibility with nitrile rubber, and can be used alone or combined with nitrile rubber to produce oil-resistant cloth hose inner and outer rubber layers, effectively reducing the cost of raw materials.
3. The oil-resistant cloth hose uses neoprene reclaimed rubber to reduce costs
Neoprene reclaimed rubber is processed from waste rubber products with high neoprene content, with good oil resistance, heat resistance, ozone resistance, weather resistance, etc., oil resistance is slightly lower than that of nitrile rubber and nitrile reclaimed rubber, and nitrile rubber and nitrile reclaimed rubber are used in an appropriate proportion to produce oil-resistant cloth hoses, reduce the cost of raw materials on the premise of maintaining the oil resistance of finished products, and further improve the flexural and aging resistance of oil-resistant cloth hoses.
4. The oil-resistant cloth hose uses tire reclaimed rubber to reduce costs
Tire reclaimed rubber is the largest output of reclaimed rubber products, processed from waste tires as raw materials, with the basic performance characteristics of rubber, but the oil resistance is weak, generally used in the outer layer of the oil-resistant E4LYY118 cloth hose. Tire reclaimed rubber can be used in combination with nitrile rubber, nitrile reclaimed rubber, neoprene, etc. to produce the outer layer of oil-resistant cloth cloth hose to ensure the overall good oil resistance of the hose.
The oil-resistant cloth hose can also use sub-brand nitrile rubber to replace nitrile rubber, which can effectively reduce the cost of raw materials. When using reclaimed rubber to reduce the cost of oil-resistant cloth hoses, rubber product manufacturers must reasonably design the hose formula, select appropriate vulcanizing agents, accelerators, reinforcing agents, fillers, softeners, plasticizers, antioxidants, etc., so as to further optimize the mechanical strength, oil resistance and aging resistance of the finished hose while reducing costs.
