Abstract

The invention discloses a method for producing 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 paraffin, and producing the rubber protecting wax product by blending. The method has the advantages of low apparatus investment, simple production process, low operation cost without solvents for polluting environment, 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 production method of rubber protective 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...
