Embodiment Construction

[0013] The present invention will be further described below in conjunction with embodiment.

[0014] In the present invention, hydrogenated nitrile rubber, carboxylated nitrile rubber and phenolic resin are ternally blended and modified, and liquid nitrile rubber is used for plasticization, so that the existing nitrile rubber formula is not wear-resistant at high temperature and has a large change in hardness. Insufficient, by using hydrogenated nitrile and carboxylated nitrile rubber as the main material, the oil resistance and wear resistance of the rubber roller are improved, and the combination of antistatic plasticizer and antistatic, liquid nitrile rubber is plasticized, and the rubber roller is improved. Antistatic performance under high speed and high temperature operation, and little change in hardness.

[0015] Examples 1-3 The raw materials were weighed according to the proportions by weight shown in Table 1, and then plasticized and glued with an open mill, and mi...

Abstract

The invention relates to a vortex spinning rubber roll; the spinning rubber roll comprises a roll core and a rubber composite material layer coating the roll core; the rubber composite material layer comprises the following raw constituent in parts by weight: 50-70 parts of hydrogenated nitrile-butadiene rubber, 30-50 parts of carboxy terminated nitrile rubber, 5-10 parts of phenolic resin, 8-15 parts of liquid nitrilo rubber, 1.5-2 parts of an accelerating agent H, 2.5 to 3 parts of an accelerating agent CZ, 0.3 part of an accelerating agent TMTD, 5-10 parts of zinc peroxide, 1-1.5 parts of stearic acid, 1-2 parts of an anti-aging agent, 4-10 parts of an antistatic plasticizer, 6-18 parts of a reinforcing agent, 1-2 parts of an antistatic agent, and 5-9 parts of a vulcanizing agent. The spinning rubber roll made by the formula provided by the invention can be applied to conditions of super draft and high-speed running; the spinning rubber roll has high wearing resistance and oil resistance, is antistatic at a high temperature and has a small rate of hardness change and a long service life.

Description

technical field [0001] The invention relates to the technical field of manufacturing textile cots, in particular to a production formula for vortex spinning cots. Background technique [0002] Vortex spinning is currently the world's fastest spinning machine, with a maximum spinning speed of 500 m / min, 20 times that of ring spinning frame and 4 times that of air spinning. The rubber roller is one of the important parts of the vortex spinning machine and an important drafting element in the spinning drafting device. The sliver is directly fed into the drafting device in the vortex spinning, and the sliver is output from the nip of the front roller and is spun immediately. The negative pressure generated by the vortex in the nozzle is inhaled to form the core fiber. When the end of the fiber is separated from the front roller (the strand passes through the rubber roller and is drawn step by step for many times), it expands due to the vortex and covers the surface of the hollow...
