Embodiment 1

[0025] Embodiment 1 preparation of white carbon black dispersant

[0026] Add 300kg of 12-hydroxystearic acid into the reactor, stir and heat to 100-110°C, then add 25kg of 58# wax and 140kg of pentaerythritol tetrastearate. After the material is completely melted, continue to stir for 15 minutes, add 30 kg of calcium carbonate and 5 kg of 2,6-di-tert-butyl-4-methylphenol and continue to stir for 15 minutes. Cool to room temperature and discharge to obtain a white carbon black dispersant. The whole process produces no waste residue and waste water.

Embodiment 2

[0027] Embodiment 2 preparation of white carbon black dispersant

[0028] Add 260kg of mixed C8-C22 fatty acids into the reactor, wherein the mixed C8-C2 fatty acids include 130kg of palm oil fatty acid and 130kg of tallow fatty acid, stir and heat to 100-110°C, then add 125kg of 58# wax and pentaerythritol tetrahard Fatty acid ester 50kg. After the material is completely melted, continue stirring for 15 minutes, add 40 kg of calcium carbonate and 25 kg of 2,6-di-tert-butyl-4-methylphenol and continue stirring for 15 minutes. Cool to room temperature and discharge to obtain a white carbon black dispersant. The whole process produces no waste residue and waste water.

Embodiment 3

[0029] Embodiment 3 preparation of white carbon black dispersant

[0030] Add 250kg of mixed C8-C22 fatty acids into the reactor, wherein the mixed C8-C22 fatty acids include 150kg of palm oil fatty acids and 100kg of soybean oil fatty acids, stir and heat to 100-110°C, then add 75kg of mixed protective wax and 150kg of palm wax, wherein , The mixed protective wax includes 50kg58# wax and 25kg polyethylene wax. After the materials are completely melted and continue to stir for 15 minutes, add 40kg of mixed inorganic fillers of calcium carbonate and calcium sulfate and 5kg of 2,6-di-tert-butyl-4-methylphenol and continue to stir for 15 minutes, wherein the mixed inorganic fillers include 35kg Calcium carbonate and 5kg calcium sulfate. Cool to room temperature and discharge to obtain a white carbon black dispersant. The whole process produces no waste residue and waste water.

Abstract

The invention discloses a white carbon black dispersant. The white carbon black dispersant comprises, by mass, 40 to 60% of C8-C22 fatty acid, 5 to 25% of protection wax, 10 to 28.8% of fatty acid ester, 6 to 10% of an inorganic filling material and 0.96 to 5% of an anti-oxidant. The invention also discloses a preparation of the white carbon black dispersant having a good white carbon black dispersion effect. The white carbon black dispersant is an environmentally-friendly high-dispersibility zinc-free white carbon black dispersant, can improve dispersibility of a filling material and rubber chemicals in rubber in rubber mixing, is suitable for improvement of dispersibility of rubber containing high-activity white carbon black, avoids re-condensation, improves wet-skid resistance of a tyre surface, and avoids the pollution produced heavy metal zinc on the environment.

Description

technical field [0001] The invention relates to the field of dispersants, in particular to a white carbon black dispersant and a preparation method thereof. Background technique [0002] In modern society, the concept of energy conservation and emission reduction has become increasingly popular. According to relevant data, 10% of global carbon dioxide emissions (2.6×106 tons) come from vehicles, which is equivalent to 1.1×1012 liters of fuel. The average fuel efficiency of global vehicles is only 10.4 liters / 100km. The main factors affecting vehicle energy consumption are: load, tire rolling resistance, driving friction, braking, engine energy consumption and air resistance. Among them, the main influencing factor of tires is tire rolling resistance, which has 15% to 30% impact on vehicle energy consumption in different degrees. The main reason for energy consumption is that tire rubber is viscoelastic, which is easy to deformation thereby increasing rolling resistance. ...
