Abstract

The invention discloses a method for preparing a liquid crystal nylon alloy. The method comprises the following steps: grinding liquid crystal oligomer and high temperature nylon oligomer, adding in a reactive screw extruder, adding a compatilizer, reacting, performing extrusion, pelletizing and tackifying solid aggregate to ensure that the relative viscosity is 2.0-3.0. By adopting the preparation method in the invention, the dosage of liquid crystals is reduced and the cost is lowered. In addition, as the compatilizer is used in the preparation method, the prepared liquid crystal nylon alloy has good surface compatibility, heat resistance, melt liquidity and processing stability and can not corrode moulds.

Example Embodiment

[0021] Example 1:
[0022] After crushing 8.5kg of liquid crystal oligomer and 1.5kg of high temperature nylon oligomer, add them to the reactive screw, add 100g of trimesic acid, react for 3 hours, extrude and cut into pellets, increase the viscosity of the pellets in solid phase for 10 hours, and complete reaction.

Example Embodiment

[0023] Example 2:
[0024] After crushing 5.0kg of liquid crystal oligomer and 5.0kg of high temperature nylon oligomer, add them to the reactive screw, add 100g of trimesic acid, react for 3 hours, extrude and cut into pellets, increase the viscosity of the pellets in solid phase for 16 hours, and complete reaction.

Example Embodiment

[0025] Embodiment 3:
[0026] After crushing 1.5kg of liquid crystal oligomer and 8.5kg of high temperature nylon oligomer, add them to the reactive screw, add 100g of trimesic acid, react for 3 hours, extrude and cut into pellets, increase the viscosity of the pellets in solid phase for 12 hours, and complete reaction.
[0027] The properties of Examples 1-3 are shown in Table 1.
