[0045] On the other hand, the embodiment of the present invention also provides a preparation method of the light liquid crystal polyester resin compound of the embodiment of the present invention described above. In one embodiment, the preparation method of the light liquid crystal polyester resin compound of the embodiment of the present invention includes the following steps:

[0046] S01. According to the components contained in the light-weight liquid crystal polyester resin compound described in the embodiments of the invention above, the raw materials of each component are weighed respectively;

[0047] S02. Drying the weighed liquid crystal polyester resin, additives, first filler, and second filler;

[0048] S03. Mixing the dried liquid crystal polyester resin, first filler, second filler, and additive to obtain a mixed material;

[0049] S04. Melting and extruding the mixed material.

[0050] Specifically, in the above-mentioned step S01, the components of the liqu...

Embodiment 1

[0061] This embodiment provides a light-weight liquid crystal polyester resin compound with low specific gravity and a preparation method thereof. Among them, the components of the lightweight liquid crystal polyester resin compound are: 64.5 parts of fully aromatic liquid crystal polyester resin (Jiangsu Water Special Material Manufacturing Co., Ltd.), 0.5 parts of dodecylphenyl POSS, 25 parts of glass fiber, talc Powder 10 parts.

[0062] The preparation method of the lightweight liquid crystal polyester resin compound is as follows:

[0063] S11. according to the ratio in the following table 1, the whole aromatic liquid crystal polyester resin, dodecaphenyl POSS, glass fiber and talcum powder are dried;

[0064] S12. Put the dried wholly aromatic liquid crystal polyester resin, glass fiber, talcum powder, and dodecaphenyl POSS into an automatic mixer for uniform mixing to obtain a mixed material;

[0065] S13. Putting the mixed material into a twin-screw extruder for melt...

Embodiment 2

[0067] The proportions by weight of the wholly aromatic liquid crystal polyester resin, dodecaphenyl POSS, glass fiber, and talcum powder selected in Example 1 were changed to 64:1:25:10, as shown in Table 1. Except for this, a wholly aromatic liquid crystal polyester resin composite was produced in exactly the same manner as in Example 1.

Abstract

The invention discloses a liquid crystal polyester resin compound and a preparation methodthereof. The liquid crystal polyester resin compound disclosed by the invention is prepared from the following components in parts by weight: 50 to 80 parts of liquid crystal polyester resin, 0.5 to 5 parts of additive, 10 to 40 parts of a first filler, and 5 to 30 parts of a second filler. The liquid crystal polyester resin compound disclosed by the invention is low in specific weight, and excellent in mechanical property, heat resisting property and machinability. The preparation method comprises the steps of firstly mixing the liquid crystal polyester resin, the additive, the first filler and the second filler, and secondly performing fusion and extrusion treatments. The preparation method can effectively ensure the property stability of the prepared liquid crystal polyester resin compound; meanwhile, the preparation method is mature in process, simple and controllable, and easy to realize industrialization.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and in particular relates to a light liquid crystal polyester resin composite and a preparation method thereof.
