Embodiment 1

[0053] This embodiment includes: A sweating and B deployment.

[0054] A: sweating

[0055] This part includes three parts: A1 soap wax sweating, A2 low melting point paraffin wax sweating and A3 high melting point paraffin wax sweating.

[0056] A1: Soap wax sweats

[0057] This part includes: (1) preparation work, (2) crystallization, (3) sweating, (4) refining and other processes.

[0058] (1) Preparation

[0059] Connect the sealing system of the sweating dish (the inner wall is a square of 1m×1m) with the pressurized buffer tank and the compressor; install the decompression buffer tank at the lower part of the sweating dish and connect the vacuum pump; connect the jacket of the sweating dish and the movable coil with the The circulation system is connected, with water as the medium; start the heating function of the circulation system to raise the temperature of the circulation water to 53°C. Put water under the sweating dish plate.

Abstract

The invention discloses a method for preparing 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 as well as 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 raw materials, and preparing the rubber protecting wax product by adjusting carbon number distribution with blending. The method has the advantages of low apparatus investment, simple preparation process, low operation cost without solvents for polluting environment, long-term and effective protection effects for rubber and products thereof, simplified formula determination process, and the like.

Description

technical field [0001] The invention belongs to the technical field of special wax preparation, in particular to a preparation method of rubber protective wax. Background technique [0002] During the processing, storage and use of rubber and its products, double bonds are broken or cross-linked under the action of ozone and other factors, causing rubber products to have surface cracks, whitening, and mechanical performance degradation. These phenomena are collectively referred to as "aging". , with the progress of the aging process, the performance of rubber and its products will gradually decrease so that it will completely lose its use value. [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-aging agents. Rubber antioxidants are divided into chemical antioxidants and physical antioxidants. Rubber protective ...
