Abstract

The invention discloses a method for producing novel rubber protecting wax. 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, a solid weight is placed on the wax layer in order to exert pressure intensity on the wax layer for accelerating separating speed of wax and oil and ensuring passing of the air-flow through the wax layer, and method can be used for rapidly and effectively removing components which are not proper for the rubber protecting wax in goods paraffin; 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, and in particular relates to a production method of a 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 ...
