Abstract

The invention discloses a method for producing a rubber protecting wax. According to the method, on the basis of a common sweating technology, air flow is utilized to carry liquid oil by a wax layer so as to forcefully separate the wax from the oil in a sweating process, and meanwhile, optimally, the raw material wax and aqueous solutions of more than two matters capable of reacting and generating gas are respectively emulsified and then sweated and the quick emission of the oil also is benefited, so that unsuitable components for the rubber protecting wax in paraffin can be quickly and effectively removed and then the rubber protecting wax product is blended and produced. The method disclosed by the invention has the advantages of low equipment investment, simple preparation process, low operation cost, no solvent pollution, long-term effective protection effect of the product for the rubber and the product thereof, and the like.

Description

technical field [0001] The invention belongs to the technical field of special wax production, in particular to a method for producing rubber protection wax. Background technique [0002] The existence of unsaturated double bonds in some rubber can make the rubber in a high elastic state, but its chemical activity makes the rubber products in the process of processing, storage and use, such as oxygen, ozone and other chemical substances in the air, as well as light, heat, radiation, mechanical Under the action of force and other factors, double bond breakage or crosslinking will occur, resulting in surface cracking, whitening, and mechanical performance degradation of rubber products. These phenomena are collectively referred to as "aging", and ozone is the main factor causing rubber aging. Rubber products, such as tires, undergo accelerated aging processes during dynamic use. As the aging process progresses, the performance of rubber and its products will gradually decreas...
