Problems solved by technology

[0005] The invention mainly solves the problem caused by uneven dispersion of white carbon black in the mixed rubber when adding a large amount of white carbon black to the existing semi-steel car radial tires and other light-colored, bright-colored, and white rubber products for rubber reinforcement. The problem that the strong effect cannot meet the technical requirements

Embodiment 1

[0016] Example 1, 45Kg of C16-C18 natural fatty alcohol after accurate metering is first thrown in the interlayer tank with heat conduction oil, and C16-C18 natural fatty alcohol begins to melt when the heat conduction oil heats up to 50°C after power-on; in C16-C18 When the natural fatty alcohol is melted to 2 / 3 of the mass, 55Kg of dodecyl hydroxystearic acid after accurate measurement is placed in the C16-C18 natural fatty alcohol semi-liquid that has mostly melted for blending; in C16-C18 During the mixing process of natural fatty alcohol and lauryl hydroxystearic acid, start the stirring paddle (slow speed) every 30 minutes to stir for 3-5 minutes to promote uniform mixing, and so on, until all the mixing is completed, strictly control the tank during the mixing process The internal temperature is within 75°C; discharge the uniformly mixed liquid of C16-C18 natural fatty alcohol and lauryl hydroxystearic acid from the discharge pipe into the holding tray (this tray should ...

Embodiment 2

[0017] Example 2, 50Kg of the accurately measured C16-C18 natural fatty alcohol is first placed in a jacketed tank with heat conduction oil, and the C16-C18 natural fatty alcohol begins to melt when the heat conduction oil heats up to 50°C after power-on; When the C18 natural fatty alcohol is melted to 2 / 3 of the mass, 50Kg of dodecyl hydroxystearic acid after accurate measurement is placed in the C16-C18 natural fatty alcohol semi-liquid that has mostly melted for blending; During the mixing process of C18 natural fatty alcohol and lauryl hydroxystearic acid, start the stirring paddle (slow speed) every 30 minutes to stir for 3-5 minutes to promote uniform mixing, and so on until all the mixing is completed, and the mixing process is strictly controlled The temperature in the tank is within 75°C; the uniformly mixed liquid of C16-C18 natural fatty alcohol and lauryl hydroxystearic acid is released from the discharge pipe into the holding pan (the pan should be made of stainles...

Abstract

The invention discloses a white carbon black dispersant for rubber products. The white carbon black dispersant is characterized by being prepared from the following raw materials in parts by weight: 45-50 parts of C16-C18 natural fatty alcohol and 50-55 parts of 12-hydroxystearic acid. A preparation method of the white black dispersant comprises the following steps: partially melting, co-melting, blending, cooling, crushing and packaging. According to the white carbon black dispersant, white carbon black is uniformly dispersed in mixed rubber, so that the agglomeration caused by adhesion is solved, the product quality is improved, energy sources are saved, and meanwhile, the cost is reduced.

Description

Technical field: [0001] The invention relates to the technical field of rubber products reinforced with white carbon black, in particular to a white carbon black dispersant for rubber products and a preparation method thereof, especially suitable for semi-steel car radial tires and other light-colored, bright-colored, white rubber products. Background technique: [0002] As a filling material with high reinforcement and low specific gravity, white carbon black is widely used in some rubber products. The number of parts (the number of parts refers to the weight of raw materials, the same below) is between 45-55 parts; for light-colored, bright-colored, and white rubber products, carbon black is extremely polluting, so it is relatively more filling with white carbon black. universal. The dispersion performance of silica in the rubber compound is extremely poor. This is because the silica material itself has a certain viscosity, and the agglomeration phenomenon in the rubber ...
