Problems solved by technology

Among them, white smoke dispersant-450 is a mixture of high-boiling alcohol and amine, which has a certain inhibitory effect on the adsorption of amine accelerators and anti-aging agents by white carbon black in rubber formulations. Therefore, adding such active agents is beneficial to the rubber compound. The quality is stable, but it has little effect on the dispersing function of silica

Abstract

The invention discloses a preparation method of a white carbon black high-activity dispersing agent composition. The preparation method comprises the following steps: weighing the following materials in percentages by weight: 20%-60% of at least one of hydrazide and sulfohydrazide, 25%-50% of long-chain fatty acid, 1%-15% of octadecanol, 1%-15% of diethylene glycol, 1%-15% of monoglyceride, 1%-20% of hexadecyl trimethyl ammonium chloride and 1%-20% of C9 resin; putting the long-chain fatty acid, octadecanol, diethylene glycol, monoglyceride, hexadecyl trimethyl ammonium chloride and the C9 resin into a negative-pressure reaction kettle; increasing the temperature; adding at least one of hydrazide and sulfohydrazide into the reaction kettle, thus obtaining the white carbon black high-activity dispersing agent composition after the reaction is finished. The preparation method is simple in technology and easy to operate; in a formula of rubber filled with white carbon black, the added composition is capable of increasing the activity of the white carbon back and improving the dispersing effect of the white carbon back in the rubber, and then enhancing the physical mechanical property of vulcanized rubber.

Description

Technical field [0001] The invention relates to a white carbon black high-activity dispersant composition and a preparation method thereof. Background technique [0002] White carbon black is an inorganic powder material. Because of its fine particles and large specific surface area, it can improve the physical and mechanical properties of tires such as puncture resistance when used in rubber tires. It can also greatly reduce tire heat generation and rolling resistance. Tire manufacturers White carbon black has been used to produce green tires that can save fuel by 10%. The range of raw materials for silica production is very wide, mainly inorganic silicate ore, straw, and coal gangue. The raw materials used for the production of carbon black are mainly non-renewable resource petroleum. Therefore, the replacement of silica for carbon black production tires will be The general trend not only saves oil resources and reduces costs, but also purifies the urban air. However, because...
