preparation example Construction

[0029] The preparation of carbon black particle dispersant of the present invention and the method for dispersing carbon black particle thereof:

[0030] 1) Configure mixed solution: mix sodium taurocholate or sodium dodecylbenzenesulfonate and sodium taurocholate with ethylene glycol at a mass ratio of 1:1, and then mix with ethanol at a mass ratio of 1:9 Mix to obtain the carbon black particle dispersant;

[0031] 2) Add carbon black powder: add 1g carbon black powder to 50ml mixed solution;

[0032] 3) Ultrasonic oscillation: put the mixture obtained in step 2) into an ultrasonic oscillator for oscillation, the temperature of the ultrasonic oscillation is controlled as an ice bath, and the oscillation time is 4 hours;

[0033] 4) Sample preparation: drop the solution of step 3) on the carbon support membrane with a pipette. Put the prepared carbon support membrane into a desiccator, and it can be detected after 24 hours;

[0034] 5) Image acquisition: use a transmission ...

Embodiment 1

[0036] 5 parts by mass of sodium dodecylbenzenesulfonate, 5 parts by mass of ethylene glycol, and 90 parts by mass of ethanol were mixed to obtain the carbon black particle dispersant 1 of the present invention. The electron micrograph of the carbon black particle dispersed through the present embodiment formula is as follows figure 1 and figure 2 shown.

Embodiment 2

Abstract

The present invention provides a carbon black particle dispersing agent, a preparation method and an application thereof. The carbon black particle dispersing agent is formed by mixing sodium dodecylbenzene sulfonate and/or sodium taurocholate, ethylene glycol and an organic solvent. With the carbon black particle dispersing agent, the dispersion of the carbon black aggregate can achieve the small state, the number of the carbon black particles in each aggregate is less, and the guarantee can be provided for the quality of the polyethylene mixing material. The carbon black particle dispersing agent can be used for preparation of high performance polyethylene pipes.

Description

technical field [0001] The invention relates to a dispersant and its preparation method and application, in particular to a carbon black particle dispersant and its preparation method and application. Background technique [0002] Polyethylene pipes have replaced steel pipes and cast iron pipes, and have been widely recognized by the society as urban gas transmission and distribution pipelines. Due to the flammability, explosiveness, and toxicity of gas, if there is a quality problem in the gas transmission system, or even gas leakage, it is extremely dangerous. It is prone to fire, explosion, poisoning and other accidents, which not only directly affect the normal life of residents, but also pose a great threat to people's lives and properties. The safety of polyethylene pipes as urban gas transmission and distribution pipelines is particularly important. As the most important part of the piping system, polyethylene pipes must be guaranteed to meet the standard requirements...
