Production method of carbon black for green tire with high wear resistance and low rolling resistance

Abstract

The invention relates to a production method of carbon black for a green tire with high wear resistance and low rolling resistance, which comprises the steps of adopting 100% high-quality anthracene oil as a production raw material, carrying out secondary treatment by a slag, oil and water three-phase separator to remove moisture and impurities, keeping the high temperature of 1950-2050 DEG C in a multi-section reaction furnace to generate carbon black reaction, adding a novel non-metal ion filler, terminating the reaction by adopting desalted softened water as quenching water, recycling waste heat of carbon black flue gas, obtaining powdery carbon black for tires with high wear resistance and low rolling resistance through collection of a bag filter box, a pipeline foreign matter removal device and the like, and finally obtaining finished carbon black through granulation of a granulator, drying, screening, magnetic cleaning, packaging and the like. The product produced by the invention has better stress at definite elongation and stronger wear resistance, which indicates that the carbon black has excellent wear resistance and low rolling resistance, and is low-rolling-resistance wear-resistant carbon black required by the current green tire industry.

Description

technical field [0001] The invention relates to a production method of carbon black for green tires with high wear resistance and low rolling resistance. Background technique [0002] In recent years, the domestic tire industry is facing various problems such as tire labeling law and other technical barriers and trade frictions. Many countries have also proposed more and more requirements on the performance of tires, and more and more countries are also constantly brewing or have implemented tire labeling regulations. [0003] At present, my country's tire industry has reached a consensus on promoting the development of green tire industrialization, and combined with my country's energy-saving and consumption-reducing requirements, formulates green tire industrialization regulations that meet national conditions.

Problems solved by technology

[0003] At present, my country's tire industry has reached a consensus on promoting the development of green tire industrialization, and combined with my country's energy-saving and consumption-reducing requirements, formulates green tire industrialization regulations that meet national conditions. One of the topics is that the tire product structure is transforming towards tubeless, wide-section, wear-resistant, wet-skid resistant, low-noise, lightweight, and high-end. However, the biggest problem currently existing in tubeless radial tires is insufficient wear resistance. Disadvantages such as high heat resistance, poor wet skid resistance, and high noise

The tire company's technicians are constantly changing the formula, such as using N134, N115, N121 and other super wear-resistant carbon blacks, but the effect is not obvious. The main reason is that these carbon blacks are traditional process carbon blacks, carbon black reaction furnaces The design is unreasonable. The combustion chamber of the traditional reaction furnace has a single air inlet and one fuel oil spray gun. The reaction inside the combustion chamber is too concentrated, resulting in unstable reaction flow rate of carbon black, uneven temperature in the combustion chamber, and the structure and particle size of carbon black. The distribution does not meet the requirements of green tires, and the additives produced by carbon black are too solidified; in the actual production of carbon black, the impurity content and moisture content in raw oil are too high, which also restricts the reaction structure of carbon black, and raw oil and Impurities such as iron filings will inevitably be produced in the production device, but the existing device has fewer links for cleaning the magnetic field and removing foreign matter, resulting in unstable product quality

Moreover, the mixing time is long, the mixing temperature is high, the energy consumption of mixing is high, the processing safety cannot be guaranteed, and the wet skid resistance is not good, the noise is large, and the hysteresis performance is obvious
