Problems solved by technology
Spinning cots are affected by various factors such as high temperature and high speed operation, super large draft ratio, heavy pressure, electrostatic effect and other factors during the spinning process. The number of roller deformation increases, the hardness of the rubber roller decreases, and the surface of the rubber roller is concave, which leads to the decline of spinning quality
The existing spinning cot formula, the raw materials used are 100 parts of nitrile rubber, 3 to 5 parts of sulfur, 1 to 3 parts of accelerator CZ, DM, 5 to 10 parts of zinc oxide, 5 to 10 parts of titanium dioxide, 1 ~3 parts of anti-aging agent, 10~30 parts of white carbon black, 1~3 parts of electrostatic agent, but the rubber roller has poor wear resistance and is easy to be concave when running at high speed and high temperature, and the short service life affects the spinning quality

Abstract
The invention relates to a production formula of a high-temperature high-speed high-wear resistant spinning rubber roll. The spinning rubber roll comprises a roll core and a rubber composite material layer coated on the roll core, wherein, the rubber composite material layer comprises 100 weight portions of hydrogenated nitrile-butadiene rubber, 6-17 weight portions of ternary copolyamide, 3-3.5 weight portions of promoter TAIC, 5-10 weight portions of zinc oxide, 1.5 weight portions of stearic acid, 1.5-2 weight portions of antioxidant, 8-15 weight portions of antistatic plasticizer, 10-25 weight portions of reinforcing agent, and 4-5 weight portions of vulcanizing agent. The produced spinning rubber roll can be applied in ultra-high drafting, high-temperature and high-speed operation conditions, and has high wear resistance and long service life.
Description
technical field [0001] The invention belongs to textile equipment technical machinery, and in particular relates to a production formula of high-temperature, high-speed, high-wear-resistant spinning rubber rollers applied under the conditions of ultra-large draft, high-temperature and high-speed operation. Background technique [0002] The rubber roller is an important component of textile machinery and an important drafting element in the spinning drafting device. During the drafting process, the fiber strands are drawn between the rubber roller and the roller. The quality of the rubber roller and The use performance directly affects the yarn quality, so the surface of the rubber roller is required to have good elasticity, wear resistance and appropriate hardness, which is beneficial to control the movement of fiber strands during the drafting process. The rollers are drawn and twisted step by step to form yarns, so the spinning rubber rollers have a direct impact on the qu...
