Anti-entangling and anti-damage rubber covered roller formula for spinning production and rubber compound preparation process thereof

Abstract

The invention provides an anti-entangling and anti-damage rubber covered roller formula for spinning production and a rubber compound preparation process thereof. The rubber covered roller comprises an aluminum tube roller core and a rubber composite material layer for coating the aluminum tube roller core. The rubber composite material layer is prepared from the following raw materials in parts by weight: 40-60 parts of carboxyl hydrogenated nitrile rubber, 40-60 parts of nitrile rubber, 5 parts of zinc oxide, 10 parts of titanium dioxide, 1.5 parts of an antiageing agent, 3-4 parts of an accelerant, 1-3 parts of an antistatic agent, 8-14 parts of an antistatic plasticizer, 1-3 parts of a functional auxiliary agent, 6-12 parts of white carbon black and 1-3 parts of a vulcanizer. The anti-entangling and anti-damage rubber covered roller formula can improve the oil resistance of the spinning rubber covered roller, prevent permeation of an oiling agent and prevent migration of a dye frompolluting the surface of the rubber covered roller. In the preparation process, a rubber plasticizing process in a conventional preparation process is canceled. A novel process of directly putting rubber (blocky rubber) into an internal mixer to be mixed to form a rubber compound is adopted, so that the process flow is shortened, the operating strength is reduced and the production efficiency isimproved.

Description

technical field [0001] The invention belongs to the technical field of textile processing, and in particular relates to the formulation of an anti-winding and anti-damage rubber roller and a preparation process for its mixed rubber in the production and manufacture of colored spinning fibers. Background technique [0002] Color spun yarn, also known as colored fiber spun yarn, is a yarn with a unique color mixing effect that is spun by fully mixing two or more fibers of different colors. Because of its multiple advantages such as environmental protection, fashion, and technology, it is very popular among consumers. [0003] During the production of chemical fibers, appropriate colorants need to be added during polymerization or spinning. After spinning and forming, the colorants are evenly dispersed in the fibers, which is called pre-spin dyeing or dope dyeing. The fibers are colored spinning fibers. . This process is a physical change, and its advantages are continuous co...

AI Technical Summary

Problems solved by technology

[0005] In the existing technology, a large number of imported rubber rollers are used, which is expensive and increases production costs. The surface of domestic rubber rollers is prone to superficial swelling, resulting in poor swelling and anti-winding stability, poor oil resistance and wear resistance, and poor surface anti-pollution ability, resulting in a substantial increase in loss. , the spinning process is unstable, not suitable for multi-batch, multi-variety (color change) production, the yarn quality decays quickly, and the evenness CVB value is poor, resulting in difficult control of spinning quality and difficult maintenance; moreover, preparation The technological process is cumbersome and complicated, and the processing and production efficiency is low, which seriously affects the normal spinning production
