Rubber material production process for adjusting charging sequence of formula containing high-part and high-structure carbon black

Abstract

The invention relates to a rubber material production process for adjusting the charging sequence of a formula containing high-part and high-structure carbon black. The rubber material production process for adjusting the charging sequence of the formula containing high-part and high-structure carbon black comprises the following steps: selecting natural rubber, carbon black and a plurality of compounding agents as raw materials according to the proportion of the formula; carrying out plastication; carrying out rubber milling; carrying out secondary rubber milling; and carrying out final rubber milling. The rubber material production process for adjusting the charging sequence of the formula containing high-part and high-structure carbon black has the advantages that the conception is skillful, the design is reasonable, the carbon black is added in two steps, part of the carbon black is added during rubber milling, the other part of the carbon black is added during secondary rubber milling, the problems that plates are discharged difficultly and broke materials are excessive when the plates are discharged are solved effectively, the production capacity can be increased by about 5%,part of secondary rubber milling is relieved effectively, production energy consumption is reduced, and the production efficiency is improved; and meanwhile, the tensile strength, the heat generationproperty and the rubber tearing property of the rubber material produced by the process are higher than those of the rubber material produced by a traditional production process, and the rubber deflection properties and the adhesion properties of two formulas are equivalent.

Description

technical field [0001] The invention relates to the field of tire manufacturing, in particular to a production process for adjusting the feeding order of a compound containing high-volume high-structure carbon black formula. Background technique [0002] In the modern tire industry, the cords of tires are all formulated with high-volume high-structure carbon black. At present, the cord formula is mainly based on N375 carbon black. The cord formula is designed to ensure its high rubber tear performance and high strength elongation, so it is necessary to add a high proportion of carbon black to the formula. The structure of N375 is as figure 1 . [0003] Due to the large number of carbon blacks in the formula, in order to ensure that its performance reaches the ideal value, N375 high-structure carbon black is added, which will cause greater difficulty in mixing. [0004] In the past, the cord fabric formulation process was plastic, section rubber, re-refining, and final rub...

AI Technical Summary

Problems solved by technology

[0004] In the past, the cord fabric formulation process was plastic, section rubber, re-refining, and final rubber compounding. All carbon black was added at one time during re-refining. In order to ensure easy sheet production, the mixing speed was reduced, but the uniformity of the rubber material in each car was relatively low. Poor, if the uniformity of the same vehicle is guaranteed to be in an ideal state, the carbon black is highly dispersed, the rubber is difficult to release, the rubber is broken, the labor intensity is increased, and the rubber is wasted, etc.
