Problems solved by technology

Adding the dispersant obtained in this invention can improve the dispersion performance of carbon black, but the self-adhesiveness of the mixed rubber is poor, the vulcanization speed is slow, and the lubricating performance is poor. If it is used improperly, the mechanical properties of the product will also be reduced.

Embodiment 1

[0017] Precipitate, filter and heat the collected waste oil or waste engine oil to remove particulate matter and moisture, add a certain proportion of activated carbon to decolorize and deodorize during the heating process, further wash with water, and conduct evaporation and dehydration to obtain waste oil products and Refined motor oil. Pump refined gutter oil and refined engine oil into a mixer at a mass ratio of 1:1 to obtain standard raw material oil. Mix 20 parts of the above-mentioned standard raw material oil with 100 parts of calcium terephthalate, then add 120 parts of carbon black and mix thoroughly.

Embodiment 2

[0019] Precipitate, filter and heat the collected waste oil or waste engine oil to remove particulate matter and moisture, add a certain proportion of activated carbon to decolorize and deodorize during the heating process, further wash with water, and conduct evaporation and dehydration to obtain waste oil products and Refined motor oil. Pump refined waste oil and refined engine oil into a mixer at a mass ratio of 1:3 to obtain standard raw material oil. Mix 10 parts of the above standard raw material oil with 20 parts of zinc terephthalate, then add 80 parts of carbon black and mix thoroughly.

Embodiment 3

[0021] Precipitate, filter and heat the collected waste oil or waste engine oil to remove particulate matter and moisture, add a certain proportion of activated carbon to decolorize and deodorize during the heating process, further wash with water, and conduct evaporation and dehydration to obtain waste oil products and Refined motor oil. Pump refined gutter oil and refined engine oil into a mixer at a mass ratio of 1:2 to obtain standard raw material oil. Mix 15 parts of the above-mentioned standard raw material oil with 25 parts of magnesium terephthalate and 25 parts of aluminum terephthalate, and then add 100 parts of carbon black and mix thoroughly.

Abstract

The invention discloses a modified carbon black and a preparation method thereof. Gutter oil and waste engine oil are refined to be made into standard raw oil, and the standard raw oil is fully mixed with terephthalic acid metal salt and carbon black according to a certain proportion. The method adopts the gutter oil and the waste engine oil as raw materials, not only realizes the comprehensive utilization of wastes, but also solves the utilization problem of the gutter oil and the waste engine oil, turns waste into wealth, and brings good social benefits. As the standard raw oil, which is low in cost, is used, the production cost of an enterprise can be reduced, and the modified carbon black has a considerable economic value. The prepared carbon black is convenient to use, and tests prove that the mechanical property of a product can be improved after the carbon black is added into the product. The carbon black is applied to natural rubber, and can improve the vulcanization reversion resistance and heat resistance of rubber materials.

Description

technical field [0001] The invention relates to a modified carbon black and a preparation method thereof. Background technique [0002] Carbon black is a material used as a performance-enhancing filler in rubber and other polymers. Due to the particularity of the surface properties of carbon black, it is difficult to disperse evenly during tire processing, which will affect the mechanical properties. Therefore, it is a major problem in the tire processing industry to make carbon black well dispersed in rubber. [0003] In order to solve this problem, people have developed some carbon black dispersants containing fatty acid soaps or surfactants. Invention patent 201310264101.5 discloses a new carbon black dispersant for rubber and its preparation method, which is composed of polyethylene wax or oxidized polyethylene wax, zinc stearate, stearic acid, polyethylene glycol, and pentaerythritol stearate. Due to the reactivity of fatty acid soaps or surfactants with other additiv...
