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] Silica is an inorganic powder material. Due to its fine particles and large specific surface area, its application in rubber tires can improve the physical and mechanical properties of tires such as puncture resistance, and can also greatly reduce tire heat generation and rolling resistance. Tire manufacturers Green tires with 10% fuel saving have been manufactured with white carbon black. The range of raw materials for white carbon black production is very wide, mainly inorganic silicate ore, straw, and coal gangue, and the raw materials for carbon black production are mainly non-renewable resource petroleum. Therefore, the production of tires produced by carbon black replaced by white carbon black will be The trend of the times not only saves oil resources and reduces costs, but also purifies the urban ai...
