Abstract

The invention discloses a poly phthalimide amide composite material and a preparation method thereof. The poly phthalimide amide composite material comprises components of the following weight portions: 45-68 portions of poly phthalimide amide, 1-20 portion(s) of heat-set liquid crystalline polymer, 1-25 portion(s) of zirconia and 10-30 portions of titanium dioxide. The components of appropriate contents interact during fusion and extrusion, so the poly phthalimide amide composite material has high whiteness, thermal stability and mechanical properties. In the preparation method of the poly phthalimide amide composite material, all the components are molten and extruded via side feeding, the preparation can be implemented on a conventional fusion extruder, no special equipment is needed, the operation and the process are simple, the efficiency is high, and the cost is low. Therefore, the preparation method is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polyphthalamide composite material and a preparation method thereof. Background technique [0002] Polyphthalamide (PPA) is a semi-aromatic nylon made of phthalic acid, and is a semi-crystalline thermoplastic functional material. PPA composite materials have excellent comprehensive physical properties, excellent high temperature resistance, high rigidity, high strength, excellent dimensional accuracy and stability and low warpage, good chemical resistance, and are resistant to heat, electricity, physics and chemicals. Good performance in terms of sex. This makes PPA composite materials have broad application prospects in the fields of electronics, electrical, and mechanical engineering. [0003] High whiteness PPA materials are more and more widely used in LED brackets and other fields. However, it is found in actual production that the existing PPA mat...
