High-speed antistatic spinning rubber roller

Abstract

The invention discloses a high-speed antistatic spinning rubber roller. The roller is characterized in that the roller comprises a roller core and a polyurethane rubber coating layer wrapping the roller core, and the polyurethane rubber coating layer is a coating layer which is prepared from an antistatic polyurethane coating synthesized from polymer polyether polyol (POP), 4,4-diphenylmethane diisocyanate and a conductive substance and has good hardness, elasticity, antistatic property, wear resistance and heat resistance. According to the spinning rubber roller, through experimental detection, compared with an existing rubber roller, the spinning rubber roller has the advantages that the hardness, elasticity, antistatic property, wear resistance and heat resistance of the spinning rubberroller are remarkably improved, the service life of the spinning rubber roller can be remarkably prolonged, and the spinning quality and efficiency of spinning machinery can be remarkably improved.

Description

technical field [0001] The invention relates to the field of textile equipment, in particular to a high-speed antistatic spinning rubber roller. Background technique [0002] The rubber roller is one of the important parts in the spinning drafting area. It can form a drafting jaw with the roller to form a certain frictional force, so as to effectively hold and draft the fiber strands, so that the fibers in the spinning triangle area are evenly affected. Therefore, the quality of the cots seriously affects the yarn quality and production efficiency of spinning. With the advancement and development of textile technology, more and more high value-added products such as blended spinning, chemical fiber, color spinning, and siro spinning are being produced. Due to the serious static electricity of raw materials during the production process, there are obvious windings in the drawing, combing and roving processes. The phenomenon of top roller greatly reduces the production effici...

Problems solved by technology

[0005] Although the above two patent documents disclose the process of making rubber rollers with rubber, and mention the need to increase the wear resistance and antistatic properties of the rubber rollers, the main raw materials of these two solutions are limited to natural rubber and nitrile butadiene Rubber, although antistatic agents and reinforcing agents are added, the rubber rollers made only have certain strength and wear resistance, but the elasticity is relatively poor, and the antistatic effect is not good. In production, due to static electricity The reason is that the phenomenon of yarn wrapping around the top roller is easy to occur, which greatly reduces the production efficiency. At high spinning speed, the surface of the rubber roller generates a lot of heat due to friction, coupled with the influence of external factors such as large draft multiple and heavy pressure, the glue The hardness of the roller is greatly reduced, and the number of deformations of the rubber roller per unit time increases, resulting in a serious decline in spinning quality and other problems
