Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a mineral-reinforced high-performance PPA material and a preparation method thereof. Background technique [0002] Polyphthalamide (PPA) is a semi-aromatic polyamide made from terephthalic acid or phthalic acid. PPA 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 between 310 and 325°C. PPA has the following basic characteristics: 1. Stronger and harder than aliphatic polyamides such as PA66; 2. Less sensitive to moisture and better thermal performance; 3. Excellent creep resistance, fatigue and chemical resistance; 4. Glass-reinforced PPA resin has a high heat deflection temperature (Heat Deflection Temperature, HDT) value, which can withstand the short-term effect of very high temperature; 5. Under normal environmental conditions, PPA resin is u...
