Embodiment 1

[0015] Example 1, 28kg of pentaerythritol, 20kg of oxidized polyethylene wax, 15kg of zinc stearate, 21kg of talcum powder, and 4kg of anti-aging agent 998-A after accurate metering were placed in the slow speed agitator successively. Anti-aging agent 998-A has Active dispersion, the first uniform mixing and stirring, while stirring, use a wooden spoon to paddle the material towards the center. The stirring time is 10-12 minutes at room temperature; Put 12kg (this product is the mother oil for making engine oil) into the primary mixing material, turn on the slow open mixer for secondary mixing, and crush the lumpy material produced during the mixing process with a wooden spoon. Stirring time at room temperature is 10-15 minutes, until the generated lump materials are completely uniformly mixed; discharge the completed secondary mixing materials into the material box, and then measure and pack them. The two times of stirring are all at room temperature conduct.

Embodiment 2

[0016] Example 2, 25kg of pentaerythritol, 15kg of oxidized polyethylene wax, 12kg of zinc stearate, 18kg of talcum powder, and 1kg of anti-aging agent 998-A after accurate metering were placed in the slow speed agitator successively. Anti-aging agent 998-A has Active dispersion, the first uniform mixing and stirring, while stirring, use a wooden spoon to paddle the material towards the center. The stirring time is 10-12 minutes at room temperature; Put 8kg (this product is the mother oil for making engine oil) into the primary mixed material, start the slow open mixer for secondary mixing, and crush the lumpy material produced during the mixing process with a wooden spoon. Stirring time at room temperature is 10-15 minutes, until the generated lump materials are completely uniformly mixed; discharge the completed secondary mixing materials into the material box, and then measure and pack them. The two times of stirring are all at room temperature conduct.

Embodiment 3

[0017] Example 3, 35kg of pentaerythritol, 25kg of oxidized polyethylene wax, 18kg of zinc stearate, 25kg of talcum powder, and 5kg of anti-aging agent 998-A after accurate metering were placed in the slow speed mixer in turn. The anti-aging agent 998-A has Active dispersion, the first uniform mixing and stirring, while stirring, use a wooden spoon to paddle the material towards the center. The stirring time is 10-12 minutes at room temperature; Put 15kg (this product is the mother oil for making engine oil) into the primary mixing material, start the second mixing in the slow open mixer, and crush the lumpy material produced during the mixing process with a wooden spoon. Stirring time at room temperature is 10-15 minutes, until the generated lump materials are completely uniformly mixed; discharge the completed secondary mixing materials into the material box, and then measure and pack them. The two times of stirring are all at room temperature conduct.

Abstract

The invention discloses a carbon black dispersing agent for rubber products and a preparation method thereof. The invention is characterized in that the carbon black dispersing agent is prepared from the following raw materials in parts by weight: 25-35 parts of pentaerythritol, 15-25 parts of oxidized polyethylene wax, 12-18 parts of zinc stearate, 18-25 parts of talcum powder, 8-15 parts of third-line oil and 1-5 parts of anti-aging agent 998-A. The preparation method comprises the following steps: primary mixing, secondary mixing, metering and packaging. The materials with certain activity capable of enhancing high-speed flowability of carbon black in the compounding process are supplemented to solve the actual state that the flowability of the existing carbon black dispersing agent can not satisfy the technical requirements of users; and the consumption of the carbon black in the rubber is low (only 2-3 parts), and the carbon black can be uniformly dispersed in the compounded rubber, thereby enhancing the production efficiency and rubber extrusion ratio and saving the labor cost and product rejection loss.

Description

Technical field: [0001] The invention relates to the technical field of fillers for rubber products, in particular to a carbon black dispersant for rubber products and a preparation method thereof. Background technique: [0002] Existing rubber products add a large amount of carbon black in the rubber compounding (adding different types of carbon black according to technical requirements). On the one hand, the purpose of adding a large amount of carbon black is to reduce the rubber content of the rubber, so as to reduce the production cost of the tire. On the other hand, carbon black is a reinforcing material for rubber, which can improve the reinforcing performance of the tire, such as reducing the wear coefficient of the tire. , Reinforce the crack resistance of sidewall rubber and improve the hardness of some rubber products. However, a large amount of carbon black filling also brings the problem of difficulty in dispersion and uneven dispersion in rubber compound mixin...
