Intelligent rubber mixing process of open mill

Abstract

The invention discloses an intelligent rubber mixing process of an open mill. The intelligent rubber mixing process comprises the following steps: according to different rubber materials, setting target values of Mooney viscosity and carbon black dispersion degree rubber mixing quality, and setting rubber mixing process procedures; in a rubber mixing process, performing random detection on rubber mixing process parameters, and performing computation by virtue of an established mathematical model to obtain a Mooney viscosity value of rubber material final mixing rubber so as to achieve the purpose of predicting the Mooney viscosity of rubber open mill mixing rubber online; selecting an online prediction mathematical model of the Mooney viscosity and the carbon black dispersion degree of a required formulated rubber material; performing correlation analysis on independent variables and dependent variables by using correlation analysis software, and establishing the mathematical model; comparing with a set target value, and judging whether the rubber material can be charged; if unqualified, automatically making an optimization scheme of the process parameters in real time according to the rubber mixing degree; and then adjusting the process parameters and continuously performing rubber mixing until the target value of the rubber mixing quality is achieved, and then discharging rubber. The intelligent rubber mixing process disclosed by the invention can achieve online control of the rubber mixing quality, and is less in investment, simple to control and significant in effect.

Description

technical field [0001] The invention belongs to the field of rubber processing, and relates to a rubber mixing method with an open mill, in particular to an intelligent rubber mixing process with an open mill. Background technique [0002] my country's rubber industry, especially the tire industry, has become the country with the largest rubber consumption in the world by 2010, and it is a veritable tire production country. However, the grade of tire manufacturing products is not high, the product quality uniformity and stability are poor, the production efficiency is low, and the energy consumption is high. . The main reason is that the advanced core technology of rubber processing has not been fully mastered, and the research on rubber processing theory and methods is still relatively backward, and rubber mixing is one of the important aspects. [0003] At present, the rubber tire industry mainly adopts a multi-stage high-temperature internal mixing process using an inter...

Problems solved by technology

There are two disadvantages: first, high-temperature rubber mixing leads to serious oxidative cracking of rubber molecular chains at high temperatures (above 140°C), which significantly reduces the physical and mechanical properties and wear resistance of rubber materials; second, the multi-stage high-temperature rubber mixing process is a continuous process. The process of heating and cooling wastes a lot of energy

For example, the Chinese patent application with the application number 200910256550.9 discloses a "production method for low-temperature rubber mixing" and the Chinese patent with the authorized announcement number 102092106B discloses a "rubber mixing and conveying device and its control system and method" , the above-mentioned existing technologies all determine the rubber mixing process parameters first, and then carry out rubber mixing under fixed parameters, but these parameters are not necessarily the optimal parameters in the rubber mixing process

China Invention Patent Authorization Announcement No. 100592972 "Open Mill Automatic Rubber Mixing Process", discloses a process for automatic rubber mixing on the open mill by using an automatic rubber turning device, an automatic rubber stamping device and an automatic feeding device to improve The efficiency of rubber mixing is improved, and labor resources are saved. The disadvantage of this patent is: because the rubber mixing process cannot be guaranteed to be carried out under the optimal rubber mixing conditions, the quality of the final rubber mixing cannot be guaranteed.
