Production formula of high-abrasion high-draft high-speed spinning rubber ring

Abstract

The invention relates to a production formula of a high-abrasion high-draft high-speed spinning rubber ring which comprises an inner rubber composite material layer, an outer rubber composite material layer and a middle framework layer. the spinning rubber ring is characterized in that the inner and outer rubber composite materials are prepared from components of, by weight, 50-80 parts of carboxylated nitrile rubber, 20-50 parts of nitrile rubber, 30-60 parts of polyvinyl chloride 2500, 20-40 parts of EVM, 1.5-3 parts of a promoter MDB, 5-10 parts of zinc peroxide, 5 parts of titanium dioxide, 1.5 parts of stearic acid, 1-2 parts of an anti-aging agent, 10-15 parts of an antistatic plasticizer, 10-20 parts of a reinforcing agent and 4-8 parts of a vulcanizing agent. The spinning rubber ring prepared by the production formula can be applied under high-draft, high-pressure and high-speed running conditions, is oil resistant, has high abrasion resistance and has long service life.

Description

technical field [0001] The invention belongs to textile equipment technical machinery, in particular to a production formula of a high wear-resistant large draft high speed spinning apron suitable for application under the conditions of large draft, high pressure and high speed operation. Background technique [0002] The apron is an important component of textile machinery and an important drafting element in the spinning drafting device. During the drafting process, the fiber strands are drawn between the upper and lower aprons, rubber rollers and rollers. The quality and performance of the apron directly affect the yarn quality, so the surface of the apron is required to have good elasticity, oil resistance, wear resistance and appropriate hardness, which is beneficial to control the movement of fiber strands during the drafting process, and the spinning process The fiber strands are drawn and twisted into yarn through the spinning upper and lower aprons, so the spinning ...

AI Technical Summary

Problems solved by technology

In the spinning process, due to the influence of various factors such as high temperature and high speed operation, super large draft multiple, heavy pressure, electrostatic effect, etc., the abrasion of the apron under super large draft multiple and heavy pressure increases. The deformation of the apron increases per unit time, causing the surface of the apron to be concave and poor in oil resistance and wear resistance, resulting in a decline in spinning quality

The existing spinning apron formula, the raw materials used are 100 parts of nitrile rubber, 60-100 parts of polyvinyl chloride, 3-5 parts of sulfur, 1-3 parts of accelerator DM, 5-10 parts of zinc oxide, 5-10 parts of Titanium dioxide, 1-3 parts of anti-aging agent, 0-20 parts of white carbon black, but the wear resistance of the apron is poor under the conditions of large draft, high wear resistance and high speed operation, easy to be concave, short service life affects spinning quality
