POLYAMIDE COMPOSITE MATERIAL, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF

WIPO Patent Application WO/2023/109458

A1

Disclosed in the present invention are a polyamide composite material, a preparation method therefor, and an application thereof. The polyamide composite material comprises the following components in parts by weight: 85-95 parts of a polyamide resin; and 5-15 parts of melamine cyanurate, wherein the sum of the parts by weight of the polyamide resin and the melamine cyanurate is 100 parts, and the pH of the melamine cyanurate is 5.0-7.5. According to the present invention, by selecting melamine cyanurate within a certain pH range and selecting proper process conditions in the material preparation process, the TVOC content of the material and the particle size distribution of melamine cyanurate in the material can be controlled, so that the IPT performance (an IPT value can reach 1500 V) of the polyamide material is effectively improved, the use requirements of products having high electrical property requirements can be satisfied; and the polyamide material is especially suitable for electronic products having a rated voltage of 1000-1500 V, and the application range of the polyamide material in the field of electronic appliances is further widened.
