Problems solved by technology

However, the solution proposed by the author to add an appropriate dispersant has the following disadvantages: (1) the antistatic agent with a huge specific surface area can have an oil absorption value several times that of its own weight, and cause the viscosity of the system to increase significantly and make it difficult to stir. Lead to uneven distribution of antistatic agent in multifunctional paste products, antistatic instability and other defects
(2) The addition of a dispersant can indeed reduce the viscosity of the multifunctional paste dipping solution. However, if you want to obtain a uniform multifunctional paste dipping solution under relatively simple conditions (such as simple mechanical stirring), you must add a large amount of dispersant for Due to the dispersion of the antistatic agent, this will inevitably lead to the softening of the multifunctional paste product and the decline in mechanical properties

Embodiment 1

[0065] 50 DOTP plasticizers were mixed with 0.1 parts of polyether silicone emulsifier, slightly stirred, and transferred to an emulsified pump for strong emulsification for 3 min. After the mixing was completed, it was poured into a 5L container having 200 parts of ethanol to form a coarse dispersion emulsion. The high-speed dispersing machine is opened, maintaining the rotational speed at 1500r / min, using high-speed mixing pad to cut the coarsely dispersed emulsion to disperse 10 min to obtain a micro-nanotic emulsion. After reaching the predetermined mixing time, stop stirring, add 10 multi-walled carbon nanotubes to the emulsion GT300, continued to stir at high speed to disperse 20 min, stop stirring again. The transfer of free ethanol was separated from the mixed liquid transfer after the secondary dispersion to obtain a concentrated paste. The concentrated paste was transferred to an oven at 110 ° C, baked for 8 h. After collecting the fully dried material, transfer to th...

Abstract

The invention belongs to the technical field of materials, and particularly relates to multifunctional paste and a preparation method thereof. The multifunctional paste comprises the following components in percentage by mass: 50-70% of PVC paste resin powder, 20-40% of a paste resin plasticizer and 0.1-10% of a high-dispersion carbon nanotube composition. The preparation method comprises the steps of preparing a plasticizer emulsion; shearing and dispersing the carbon nanotubes; concentrating and drying the dispersion; and preparing the multifunctional paste. The multifunctional paste has the beneficial effects that the high-dispersion carbon nanotube composition used in the preparation process of the multifunctional paste forms a high-dispersion carbon nanotube-emulsion dispersion under the promotion of high-speed shearing and interaction force between micro-nano emulsion-carbon nanotube bundles and environment-friendly plasticizer molecules. The high-dispersion carbon nanotube composition does not pulverize, does not leak oil, is high in dispersion, is convenient to use, and is especially suitable for the fields of low-toxicity, healthy, environment-friendly and safe permanent antistatic, conductive and electromagnetic shielding.
