Embodiment 1

[0015] Follow the steps below:

[0016] (1) Mastication: Under the condition of 50°C, use an open mill to masticate for 10 minutes; during the thin pass process, adjust the roller distance to 1.0mm, control the roller temperature at 45°C, and put the film into the gap between the rollers for thin pass 10min;

[0017] (2) Mixing: The temperature of the front roller is maintained at 60°C, and the rear roller is at 55°C. Put plasticized rubber into the roll gap, wrap it evenly on the front roller, remove the glue, adjust the roller distance to 1.5mm, and wrap the rubber on the Put the compounding agent into the front roller; the order of adding the compounding agent is: natural rubber plastic glue - anti-aging agent - zinc oxide - carbon black - 30# engine oil - sulfur, during the process of adding the compounding agent, pound the rubber for 2 Second; adjust the roller distance to 0.5mm, turn over for 10min; adjust the roller distance to 3mm, and release the film; park the rolle...

Abstract

The invention relates to a method for manufacturing truck tire rubber. The method comprises the following steps of plasticating, mixing, calendering, vulcanizing, molding and the other steps, wherein in the mixing process, the plasticated rubber is put into a roll gap and evenly wrapped on a front roller, after the rubber is removed, the roller distance is adjusted to be 1.5mm, the rubber is again wrapped on the front roller and a compounding agent is put in the sequence of natural plasticated rubber, an auxiliary material, zinc oxide, carbon black, No.30 engine oil and sulfur, and the auxiliary material can be one of a promoting agent, an anti-aging agent and stearic acid. The tire prepared from the rubber composition disclosed by the invention is environment-friendly and safe and has excellent flexibility resistance and fatigue resistance.

Description

technical field [0001] The invention relates to a rubber processing technology, in particular to a method for making rubber for truck tires. Background technique [0002] There are multiple environmental pollution factors in the existing tire rubber formulations, such as polycyclic aromatic hydrocarbons, which are internationally recognized as carcinogenic chemicals. The content of polycyclic aromatic hydrocarbons in certain operating oils in rubber is very high, which has brought health risks to processors and users. Secondly, many additives in rubber and some synthetic rubbers will produce nitrous acid substances during processing and production. Nitrous acid substances are also recognized carcinogens and also threaten people's health. [0003] In addition, during the use of truck tires, due to the longer driving time compared with other specifications of tires, the heat accumulation of tires is relatively large, so the heat generation and heat resistance of each part of ...
