Abstract

The invention relates to a rotor spinning rubber roller which comprises a roller core and a rubber composite material layer wrapping the roller core. The rubber composite material layer comprises, by weight, 70-80 parts of carboxyl acrylonitrile-butadiene rubber, 15-30 parts of hydrogenated acrylonitrile-butadiene rubber, 5-10 parts of magnesium methylacrylate, 5-10 parts of liquid acrylonitrile-butadiene rubber, 4-8 parts of antistatic plasticizing agents, 2-3 parts of promoting agent DM, 0.2-0.4 part of promoting agent, 5-10 parts of zinc peroxide, 1-1.5 parts of stearic acid, 1-2 parts of anti-aging agents, 20-30 parts of reinforcing agents, 1-3 parts of functional aids and 5-9 parts of vulcanizing agent. The manufactured rotor spinning rubber roller can be applied to high-speed operation conditions larger than one hundred thousand revolutions per minute, the surface of the rotor spinning rubber roller does not need to be chemically treated, and the rotor spinning rubber roller can be used and is antistatic under high-speed and high-temperature conditions, small in hardness change rate, resistant to abrasion and oil and long in service life.

Description

technical field

[0001] The invention relates to a production formula of a rotor spinning rubber roller, which belongs to the technical field of manufacturing textile rubber rollers. Background technique

[0002] Rotor spinning is one of the high-speed spinning machines in the world at present. The highest rotor speed has reached 160,000 rpm, which is 20 times that of the ring spinning machine. The rubber roller is one of the important parts of the rotor spinning machine and an important drafting element in the spinning drafting device. The rotor spinning completes the fiber conveying, cohesion, and drying through the high-speed rotating cup and the negative pressure in the cup. A new spinning method that combines, drafts with rubber rollers, and twists into yarn. The quality and functional performance of cots directly affect the quality of yarn. Therefore, cots are required to have excellent antistatic properties, wear resistance, heat resistance and suitable hardness in sp...
