Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Examples and comparative examples are given only to further illustrate the present invention, and the present invention is not limited to the following examples.

[0029] The low hysteresis carbon black of the present invention can be prepared by using a carbon black reaction furnace. The carbon black reaction furnace is a common equipment in the prior art. It generally includes a combustion section, a throat section, a reaction section and a quenching section; wherein the throat section is provided with a raw material oil spray system (main raw material oil spray system), which can be used to spray into The main raw material oil. In order to inject auxiliary raw material oil, an auxiliary raw material oil spray system is added at the rear of the combustion section in front of the main raw material oil spray system.

[0030] Such as figure 2 As shown,...

Abstract

The invention provides low-hysteresis carbon black and a production method thereof. The low-hysteresis carbon black has the characteristics that the oil absorption value is 131-145 ml / 100 g, the compression oil absorption value is 102-114 ml / 100 g, the iodine absorption value is 115-131 mg / g, and the nitrogen adsorption specific surface area is 119-130 m < 2 > / g. A tire manufactured using the low-hysteresis carbon black has low rolling resistance and low heat accumulation under use conditions.

Description

technical field [0001] The invention relates to carbon black and a preparation method thereof, in particular to hard carbon black which balances wear resistance and low heat generation and a production method thereof. Background technique [0002] Carbon black is currently known as the blackest material in the world. It is widely used in rubber, ink, plastic, colorants and other products to endow the products with the required reinforcement, dyeing or electrical conductivity. Carbon black is produced by incomplete combustion or cracking of hydrocarbon compounds, and its basic composition is elemental carbon (accounting for 95% to 99%). It is in the form of very fine powder and has a high specific surface area. [0003] As a rubber reinforcing material, carbon black has been widely used in the rubber industry. However, there are still many problems to be solved in the current commercial carbon black, such as how to further reduce its rolling resistance, improve its wet skid ...
