Example Embodiment

[0052] Example 1

[0053] This embodiment includes two parts: A sweating and B blending.

[0054] A: sweating

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

[0056] A1: Soap and wax sweat

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

[0058] (1) Preparation

[0059] Connect the sealing system of the sweat dish (with an inner wall of 1m×1m square) to the pressurized buffer tank and compressor; install a decompression buffer tank under the sweat dish and connect the vacuum pump; connect the sweat dish jacket and the movable coil to the The circulation system is connected with water as the medium; the heating function of the circulation system is activated to heat the circulating water to 53°C. Pad water under the sweat pan 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 ...
