Abstract

The invention discloses an accessory ingredient pre-dispersed masterbatch and a preparation technology thereof. Powdery or granular accessory ingredient is dispersed into a rubber matrix to form a new evenly-mixed flaky accessory ingredient form which has small possibility of flying. The preparation technology has the beneficial effect that the accessory ingredient is pre-dispersed in the rubber matrix. Compared with the traditional powder or granules, the accessory ingredient pre-dispersed masterbatch is characterized in that the flaky masterbatch does not have flying and scattering loss in the using process to guarantee the accuracy of the formula and improve the quality and the stability of the sizing material; because the accessory ingredient is subjected to the pre-dispersed mixing process, the accessory ingredient masterbatch can be quickly and easily dispersed into the sizing material in the using process, and the dispersibility of the accessory ingredient as well as the uniformity and the production efficiency of the sizing material are improved; the flaky accessory ingredient pre-dispersed masterbatch is more suitable for automatically or semi-automatically weighing, the automation degree of the whole production system is improved, and the production efficiency is improved.

Description

technical field

[0001] The present invention relates to a new form of raw materials in the manufacture of tires and other rubber products, in particular to a new form of auxiliary agents used in rubber compounding process and its preparation method. Background technique

[0002] The rubber mixing process is the first link in the production process of rubber products, especially tires. The quality of the rubber mixing effect is directly related to whether the following processes can be carried out smoothly and the final quality of the product.

[0003] The rubber mixing process is the process of fully mixing natural rubber, synthetic rubber or other types of rubber with various fillers, plasticizers, anti-aging agents, vulcanizing agents and other chemical additives. The rubber mixing is carried out in an internal mixer or on an open mill.

[0004] The traditional rubber mixing process is generally divided into two steps, master mixing and final mixing. Masterbatch is the p...
