AI Technical Summary

Problems solved by technology

Traditional powder-type rubber additives (accelerators, vulcanizing agents, active agents, etc.) produce a lot of dust during the application process, which is difficult to disperse in the rubber efficiently and evenly, so there are a series of quality and energy consumption problems; Dispersed masterbatch can solve this series of problems
[0003] The traditional pre-dispersed masterbatch is prepared by using 70%-80% powder rubber additives, adding softening oil and rubber mixing, but it will have disadvantages such as poor processing performance and high energy consumption.

Embodiment 1-6

[0017] Embodiment 1-6, comparative example 1-3

[0018] Embodiments 1-6 and Comparative Examples 1-3 all provide a kind of pre-dispersed masterbatch, and its composition is as shown in Table 1:

[0019] Table 1 embodiment 1-6, the composition of comparative example 1-3

[0020]

[0021] From Table 1, it can be found that the Mooney viscosity can be significantly reduced by adding silicone additives, and the Mooney viscosity at 50°C can be reduced by more than 10, which can effectively improve the processing performance of pre-dispersed masterbatch particles, reduce energy consumption, and make the masterbatch The grains are smooth in appearance.

[0022] It can be seen from Table 1 that when the processing oil is 8%, the raw rubber is 10%, the silicone additive is 4%, and the powder rubber additive is 80%, the effect is the best.

Embodiment 7-12

[0024] Embodiment 1-6, comparative example 1-3 all provide a kind of pre-dispersed master batch processing method,

[0025] The materials of Examples 1-6 were mixed uniformly and granulated respectively.

Abstract

This application relates to a pre-dispersed masterbatch, including the following components by mass percentage: powder rubber additives: 70%-80%, processing oil: 8%-13%, raw rubber: 4%-10%, silicon Ketone builders: 4%‑8%. It can effectively improve the processing performance of pre-dispersed masterbatches, reduce energy consumption, and make the appearance of masterbatches smooth.

Description

technical field [0001] The application belongs to the technical field of rubber preparation, and in particular relates to a pre-dispersed masterbatch and a processing method. Background technique [0002] Rubber additive pre-dispersion, also called rubber additive masterbatch. Pre-dispersed rubber additives use polymers as carriers, add rubber additives and softeners, and pre-disperse traditional rubber additives into polymers through special processes to obtain a uniform pre-dispersion with a certain concentration (extrusion granulation). Pre-dispersed rubber additives are an upgraded product of traditional rubber additives. They have the advantages of no dust, easy dispersion, suitable for automatic weighing and automatic continuous low-temperature mixing, improved mixing efficiency, and good storage stability. They have been increasingly valued by the industry and have become It is widely used in rubber products. Traditional powder-type rubber additives (accelerators, v...
