Production formula for spinning rubber roller with high oil resistance and compression resistance

Abstract

The invention relates to a production formula for a spinning rubber roller with high oil resistance and compression resistance. The spinning rubber roller comprises a roller core and a rubber composite layer coated on the roller core; the roller core is made of an aluminum tube with inner diameter surface roughness Ra less than 0.09; the rubber composite layer comprises the following raw materialsin parts by weight: 60-80 parts of carboxy nitrile rubber, 20-40 parts of butyronitrile pre-crosslinked rubber, 5-20 parts of carboxyl-terminated liquid nitrile butadiene rubber, 1.5-4 parts of functional wear-resisting agent, 1.5-3 parts of accelerant, 3-8 parts of cross-linking active agent, 5 parts of titanium dioxide, 1.5 parts of stearic acid, 1-2 parts of anti-aging agent, 1-3 parts of antistatic agent, 6-20 parts of fortifier and 4-8 parts of colloidal sulfur. The invention is capable of improving the current situation that the present nitrile rubber formula is not oil-resisting and iseasy to concave and deform under the running conditions of spinning cellulosic fiber, siro spinning, large drafting and no spinning stroke.

Description

technical field [0001] The invention belongs to the technical field of manufacturing textile rubber rollers, in particular to a production formula of high oil resistance (tencel fiber) pressure-resistant spinning rubber rollers. Background technique [0002] Spinning cots are one of the important drafting components in the drafting device of textile machinery spinning frame. During the spinning process, the sliver is drafted by the upper and lower aprons, and its function is to control the fiber elongation and effectively control Fiber movement, control floating area, improve yarn evenness quality. Spinning cots contain a large amount of spinning oil in the cellulose fiber (especially Tencel) during the spinning process, and the spinning process requires no yarn guide stroke (less than 4 mm), so the cots have been in the super large traction for a long time. Elongation, high-speed operation under heavy pressure, and the influence of various factors such as spinning oil, res...

Problems solved by technology

Spinning cots contain a large amount of spinning oil in the cellulose fiber (especially Tencel) during the spinning process, and the spinning process requires no yarn guide stroke (less than 4 mm), so the cots have been in the super large traction for a long time. Elongation, high-speed operation under heavy pressure, and the influence of various factors such as spinning oil, resulting in a decline in the oil resistance, antistatic, and pressure denaturation of the rubber material, resulting in swelling of the rubber roller surface, poor wear resistance, and concave. The grinding cycle of the rubber roller is shortened, the overall service life is short and the spinning quality is affected
