preparation example Construction

[0030] Another aspect of the present invention provides a method for preparing a liquid crystal polyester resin compound with antistatic adsorption, comprising the steps of:

[0031] Provide a wholly aromatic liquid crystal polyester resin, glass fibers and carbon nanotubes, mix the wholly aromatic liquid crystal polyester resin, the glass fibers and the carbon nanotubes uniformly, then melt and knead, and extrude, obtaining the liquid crystal polyester compound;

[0032] Wherein, based on a total of 100 parts by weight, 50-89 parts of the wholly aromatic liquid crystal polyester resin, 1-10 parts of the carbon nanotube, and 10-40 parts of the glass fiber.

[0033] In the example of the preparation method of the above-mentioned liquid crystal polyester resin compound, each component is mixed according to the proportion and melted, kneaded and extruded, so that the carbon nanotubes and glass fibers can be fully dispersed in the base resin of the wholly aromatic liquid crystal p...

Embodiment 1

[0042] This embodiment provides a liquid crystal polyester resin compound with antistatic adsorption, and its preparation method specifically includes the following steps:

[0043] S11, material preparation

[0044] Weigh 69 parts by weight of a wholly aromatic liquid crystal polyester resin (purchased from Jiangsu Water Special Material Manufacturing Co., Ltd.) and 30 parts by weight of glass fibers, and dry them at 130°C for 4 hours to obtain a wholly aromatic liquid crystal polyester resin and glass fiber. fiber dry matter.

[0045] S12. Melt mixing and extrusion

[0046] Weighing 1 part by weight of carbon nanotubes, putting the carbon nanotubes and the above dry matter into an automatic mixer to mix evenly, then putting the mixture into a twin-screw extruder for melting and mixing, and then extruding, drawing, cooling, and making pellets to obtain the liquid crystal polyester composite.

Embodiment 2

[0048] The difference between this embodiment and Embodiment 1 is: 67 parts by weight of a wholly aromatic liquid crystal polyester resin, 3 parts of carbon nanotubes, and 30 parts of glass fibers. The rest are basically the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention belongs to the technical field of high molecular composite materials, and particularly relates to a liquid crystal polyester resin compound having antistatic adsorption effect and a preparation method thereof. The liquid crystal polyester resin compound comprises, by 100 weight parts in total, 50-89 parts of wholly-aromatic liquid crystal polyester resin, 1-10 parts of carbon nanotube and 10-40 parts of glass fiber. Compared with the prior art, the liquid crystal polyester resin compound has the advantages that by adopting the wholly-aromatic liquid crystal polyester resin as a basic resin component and adopting the carbon nanotube and the glass fiber to modify the wholly-aromatic liquid crystal polyester resin, the liquid crystal polyester resin compound is endowed with goodantistatic adsorption effect, and the technical problem that conventional liquid crystal polyester resin materials are prone to adsorbing dust is solved.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a liquid crystal polyester resin compound with antistatic adsorption function and a preparation method thereof. Background technique [0002] Liquid crystal polyester resin (LCP) is widely used in electronics, electricity, automobiles, aerospace and other fields because of its excellent electrical insulation, heat resistance, dimensional stability, and good fluidity when melted. Supplies, printed circuit boards, food packaging, satellite electronic components, electrical and electronic and automotive components, etc., and even as exterior panel materials for spacecraft. However, this type of material has a certain degree of electrostatic adsorption. In the actual application process, the surface of the material will absorb the dust existing in the environment. As time goes by, it will lead to a large amount of dust accumulation, which will affect t...
