Injection molding method of high-temperature-resistant rubber roller

Abstract

The invention relates to an injection molding method of a high-temperature-resistant rubber roller. In the method, natural rubber is used as a main material, carbon black is used as a reinforcing filler, acrylic rubber is used for enhancing high temperature resistance of the rubber roller, and the high-temperature-resistant rubber roller is prepared by an injection molding technique. The method for producing the textile drafting rubber roller solves the problem of degumming, and obviously improves the high temperature resistance of the rubber roller.

Description

technical field [0001] The invention relates to a high-temperature-resistant rubber roller, especially a drafting rubber roller in textile equipment, and an injection molding method thereof. Background technique [0002] In the spinning process, the yarn is changed from thick to thin through the drafting device in the spinning equipment. The rubber roller is the key component in the drafting device. In the drafting device, the fiber bundles During the drafting operation, the quality and performance of the yarn will directly affect the yarn evenness, yarn defect, strength, broken end rate and flower return rate. With sufficient holding force, the spinning machine adheres and drafts the fibers many times through the spinning cots, twists them into yarn, and the spinning cots have a direct impact on the quality and output of the yarn. At the same time, it is also noticed that the yarn is repeatedly pulled on the rubber roller at high speed, and the friction between them will ...

Problems solved by technology

The current research direction is mainly focused on the surface quality of rubber rollers, such as patents 01131719.1, 02112811.1, 200410053380.1, etc., although the surface quality of rubber rollers has been improved to a certain extent, but the holding force between rubber rollers and fiber bundles has not been fundamentally improved. , and did not improve the heat resistance of the rubber roller

In addition, there are few studies on improving the surface quality of rubber rollers from the perspective of rubber roller processing technology.

The existing technology for producing textile drafting rubber rollers generally adopts the process of steam vulcanization after extrusion. This original process has the following problems: 1. The vulcanization time is relatively long, and the vulcanization medium is water vapor, which is easy to cause product damage during the vulcanization process. 2. The production process is complicated, various consumption is high, and the rubber is easy to burn; 3. The operation is difficult, and it is difficult to fully combine with the skeleton material, and the ideal holding force cannot be obtained.
