preparation example Construction

[0028] Another aspect of the embodiment of the present invention also provides a preparation method of easily dispersible high-content filler masterbatch, comprising:

[0029] (1) The carrier, filler, dispersant, coupling agent, surfactant, antibacterial agent and solvent are mixed uniformly according to the composition of the aforementioned easily dispersible high-content masterbatch to form a slurry, and then the slurry is dried to form a paste shape;

[0030] (2) subjecting the paste to single-screw cutting granulation and drying to obtain easily dispersible and high-content masterbatches.

[0031] Further, the solvent includes any one of water and ethanol, and is not limited thereto.

[0032] Further, the solvent is preferably water.

[0033] In some specific embodiments, the preparation method includes: dispersing the carrier in a solvent, then adding a dispersing agent, a coupling agent, a surfactant, and an antibacterial agent at 25-80° C. and stirring until completel...

Embodiment 1

[0042] Heat 2000ml of deionized water to 80°C, add 20g of PVP K30 in batches, until it is completely dissolved, the solution is pale yellow; 20g of dispersant sodium dodecylbenzenesulfonate, 1g of coupling agent DN-8311W, 10g of fatty acid Ethanolamide and 10g vanillin were dissolved in the above-mentioned solution successively. To be completely dissolved, 950g of graphene was accurately weighed and placed in a container, poured into the above-mentioned solution in batches, and stirred by hand until all the powders were wetted; Stir continuously for 30 min at / min to obtain graphene slurry; place the above slurry in a blast drying oven at 120 ° C, and dry it to a paste; open the single-screw granulator, adjust the rotation speed to 500 rpm, and dry the paste Orderly and slowly put it into the single-screw feeding port for granulation; place the prepared granules in a blast drying oven at 120° C. to completely dry to obtain graphene antistatic masterbatches.

Embodiment 2

[0044] Heat 1500ml of deionized water to 50°C, add 100g of PVP K60 in batches, until it is completely dissolved, the solution is pale yellow; 20g of dispersant sodium dodecylbenzenesulfonate, 10g of coupling agent DN-8311W, 10g of fatty acid Diethanolamide and 10 g of vanillin were dissolved in the above solution in turn. After they were completely dissolved, 900 g of carbon nanotubes were accurately weighed and placed in a container, poured into the above solution in batches, and stirred by hand until all the powders were wetted; Continue stirring at 800 rad / min for 40 min to obtain carbon nanotube slurry; place the slurry in a blast drying oven at 120°C and dry it to a paste; turn on the single-screw granulator, adjust the rotational speed to 500 rpm, and put the The paste is slowly and orderly put into the single-screw feeding port for granulation; the obtained granules are completely dried in a blast drying oven at 120° C. to obtain carbon nanotube antistatic master batches...

Abstract

The invention discloses an easily dispersible high-content master batch and a preparation method and application thereof. The master batch includes the following components calculated in parts by weight: 2-20 parts of carriers, 80-98 parts of fillers, 2-5 parts of dispersants, 0.1-2 parts of coupling agents, 0.1-2 parts of surfactants and antibacterial agents 1-9 parts of agent; wherein, the carrier comprises polyethylene glycol and / or polyvinylpyrrolidone, and the size of the filler is micron and / or below micron. The preparation method of the present invention has the advantages of simple process, extremely low energy consumption, low cost, low processing temperature and the like, and at the same time, the master batch of the present invention has a high content of active ingredients and can be well integrated with most polymer resins.

Description

technical field [0001] The invention belongs to the technical field of plastic master batch preparation, and particularly relates to an easily dispersible high-content master batch and a preparation method and application thereof. Background technique [0002] With the development of society, people's diverse needs increase, and the requirements for plastic functions are also increasing. Most of the traditional methods are to control the structure of plastics, prepare plastic alloys, and add functional fillers to improve the properties of plastics. Among them, the structural control technology can achieve performance enhancement without increasing the number of plastic phases, but its development is difficult, has a great impact on the performance of the plastic body, has a long development cycle, a high failure rate, and a high development cost. High-end materials, it is difficult to quickly solve existing problems. Plastic alloys can synthesize the excellent properties o...
