Abstract

The invention discloses a high temperature nylon PPA reinforcing material and a preparation method thereof. The high temperature nylon PPA reinforcing material comprises the following components in part by weight: 30 to 50 parts of polyphthalamide, 8 to 20 parts of polyamide, 10 to 15 parts of main fire retardant, 3 to 5 parts of assistant fire retardant, 30 to 45 parts of filling reinforcing agent, 0.2 to 0.6 part of antioxidant, 0.2 to 0.8 part of lubricant, and 0.3 to 0.6 part of nucleating agent. The invention overcomes the defects of lower liquidity and difficult processing of the PPA because a polyamide material is introduced; the polyamide material has the characteristics of high liquidity and similar molecular structure, and can be well fused with the PPA material, so that the liquidity is improved, the processing temperature is greatly reduced, and the processing procedure is simplified; and a modified material with excellent performance after being reinforced by a glass fiber is equal to foreign brand materials, and plays a role in laying the foundation for domestic volume production and future quantity demand in the domestic market.

Description

[technical field] [0001] The invention relates to the technical field of polymer materials, in particular to a high-temperature nylon PPA reinforcing material and a preparation method thereof. [Background technique] [0002] Polyphthalamide (referred to as PPA) is a new type of high-temperature-resistant, high-performance special engineering plastic that was first developed and mass-produced by Solvay. It has the advantages of high rigidity, high heat resistance, high strength and excellent electrical properties. Polyphthalamide is a semi-crystalline thermoplastic aromatic polyamide, commonly known as aromatic high-temperature nylon. It is a high-temperature-resistant material with a melting point of 310-325°C and a heat distortion temperature of 260°C. Between -280°C, its melting point is higher than that of PA46 and PPS; under high temperature and high humidity, the tensile strength of PPA is 20% higher than that of nylon 6, and higher than that of nylon 66; the flexural ...
