AI Technical Summary

Technical Problem

Existing rubber protective wax production has high requirements for raw material properties, low product yield, and requires the addition of other additives. Furthermore, the chemical composition of petroleum wax fluctuates greatly, resulting in unstable protective effects of rubber protective wax.

Method used

Rubber protective wax is prepared by refining ketone-benzene triple-line deoiling wax and ketone-benzene quadruple-line deoiling wax with bleaching clay to remove unsuitable components, and then precisely controlling the proportions through static mixing and self-circulating sedimentation processes.

Benefits of technology

The increased content of effective ingredients in rubber protective wax extends the protective time of rubber products, meets quality standards, reduces production costs, and improves economic efficiency.

Abstract

This invention provides a method for preparing rubber protective wax, comprising the following steps: refining ketone-benzene triple-oiled wax and ketone-benzene quadruple-oiled wax with bleaching clay to obtain triple-oiled wax blending raw material oil and quadruple-oiled wax blending raw material oil; blending the triple-oiled wax blending raw material oil and quadruple-oiled wax blending raw material oil, followed by static mixing, to obtain a first oil product; circulating the first oil product to obtain a second oil product; allowing the second oil product to settle and removing water to obtain a third oil product; and molding the third oil product to obtain rubber protective wax. The ketone-benzene triple-oiled wax and quadruple-oiled wax used in this invention are refined with bleaching clay to remove unsuitable components for rubber protective wax from the raw materials. After being blended using a precisely controlled proportioning system, the produced rubber protective wax product exhibits superior performance and meets the requirements of NB / SH / T 0871-2021.
