Formula for in situ preparing rolled high brightness shoe side rubber and preparation method thereof

Abstract

The invention discloses a formula for in situ preparing rolled high brightness shoe side rubber and a preparation method thereof. By parts by weight, the formula comprises 75-100 parts of natural rubber, 0-25 parts of synthetic rubber, 1.7-2.5 part of vulcanizer, 2.6-5.5 parts of vulcanization accelerator, 3.0-5.0 parts of vulcanization activating agent, 10-26 parts of softening system, 80-160 parts of reinforcing rubber and 9.5-11.0 parts of colour masterbatch. The product prepared by the invention is high brightness rubber prepared by high temperature vulcanization. The method utilizes molecular action of compounding agent instead of special brightener, in situ preparing is adopted to prepare high brightness rubber, and the method has the characteristics of simple operation, safe process and low production cost. The obtained product has good properties, thus fully meeting the requirement of consumer.

Description

technical field [0001] The invention relates to a rubber processing technology, in particular to a formula and a preparation method for calendering in-situ high-gloss shoe edge rubber. Background technique [0002] The shiny rubber parts of rubber shoes products is a demand trend. The higher the brightness of the rubber parts of shoes, the more they are favored by consumers. Among the rubber shoes products with the same internal performance, the higher the brightness of the rubber material, it represents the product quality. higher. Under normal circumstances, the brightness of the outsole of rubber shoes of model products can meet the high brightness requirements by polishing the pattern surface of the mould. However, rubber shoes produced by calendering process have a semi-bright or dull appearance of the rubber parts, which gives people a rigid and dull appearance. obsolete. In order to obtain higher brightness, one method is to apply a layer of liquid brightener on the...

Problems solved by technology

However, the brightness of the rubber shoes produced by this method makes people feel unnatural and uncomfortable. At the same time, this production method has complicated processes, high production costs, and low product competitiveness. The product brightness is greatly affected by the quality of the liquid brightener. The aging crack of the brightener on the surface of the rubber part will be caused by the quality change of the brightener, which will affect the product image and the qualified rate of product production

Another method is to add a large dose of brightener to the rubber in the form of raw materials to increase the surface brightness of vulcanized rubber products. In this method, due to the high cost of the brightener, and the need to add a large dose to meet the brightness requirements, so Product cost is relatively high and competitiveness is low
