Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of the poor antistatic effect of the spinning cots in the existing rotor cup spinning at high speeds, which are prone to entanglement, cannot operate normally, the oil resistance decreases at high temperatures, the wear increases, and the hardness of the cots decreases. The disadvantage of short life is to provide a rotor spinning cot with good wear resistance and antistatic properties and long service life

Embodiment Construction

[0015] The present invention will be further described below in conjunction with specific examples.

[0016] Table 1 shows the parts by weight of each component in the rotor spinning cots in Examples 1-3. The raw materials are accurately weighed according to the ratio of the raw materials, and then the open mill is used for masticating and gluing. The rubber mixer is mixed to make rubber products.

[0017] Table 1 Formulas of three kinds of rotor spinning cots

[0018]

[0019] Using the rotor spinning cots of the traditional formula in the prior art as a comparative example, the three kinds of rubber products for preparing rotor spinning cots obtained in Examples 1 to 3 were prepared in accordance with "GB / T528-2009 ", "GB / T531.1-2008", "GB / T1689-1998", "GB / T3512-2001" testing standards were respectively tested for tensile stress-strain properties, hardness, thermal aging, etc. The results are shown in Table 2 Show:

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 uses the high-speed rotating rotor and the negative pressure in the cup to complete the fiber transportation, cohesion, and 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 spin...
