Abstract

The invention discloses a method for producing novel rubber protecting wax. The method is based on common sweating and de-oiling processes, in a sweating process, air-flow passes through a wax layer for carrying liquid state oil in order to compulsively separate wax and oil; at the same time, gas generated by decomposition of inorganic salt forms micro spaces in the wax layer, so that components which are not suitable for the rubber protecting wax in goods paraffin are rapidly and effectively removed; components obtained by sweating and alpha-olefin are blended in order to produce the rubber protecting wax product. The method has the advantages of simple production process, low operation cost, long-term and effective protection effects for rubber and products 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 novel rubber protective wax. Background technique [0002] During the processing, storage and use of rubber products, under the action of ozone and other chemical substances in the air and other factors, the surface of rubber products will be cracked, whitened, and mechanical properties will decline. These phenomena are collectively referred to as "aging". As the process progresses, the performance of rubber and its products will gradually decrease so that it will completely lose its use value. Ozone is the main factor causing rubber aging. Rubber products, such as tires, undergo accelerated aging processes during dynamic use. [0003] In order to prolong the storage period and service life of rubber and its products, it is necessary to add some substances that can inhibit the aging process to the rubber. These substances are called anti-ag...
