Problems solved by technology

[0002] Polyethylene terephthalate (PET) is a crystalline polymer with high melting temperature and glass transition temperature, which maintains excellent physical and mechanical properties in a certain temperature range, and its fatigue resistance , friction resistance, aging resistance, and electrical insulation are extremely prominent, relatively stable to most organic solvents and acids, and have low production energy consumption, so they are widely used in the fields of synthetic fibers, films, and engineering plastics; but PET is There are disadvantages such as low toughness, poor flame retardancy, slow crystallization speed, high mold temperature and long molding cycle, which will greatly limit its application range
Polytrimethylene terephthalate (PTT) is a crystalline polymer with fast crystallization speed, low melting temperature and glass transition temperature. It has particularly excellent softness, elastic recovery, processability, electrical properties, and mechanical properties. and dimensional stability; however, PTT has defects such as low notched impact strength, high notch sensitivity, low dimensional stability, poor heat resistance, and poor flame retardancy, which will limit its application field

Abstract

The present invention discloses a high-fire-retardant, high-impact-grade, low-grass and functionalized PET / PTT alloy, which comprises the following components in mass percentage: 32-62% of PET, 20-30% of PTT, 2-4% of SMA, 8-15% of modified calcium carbonate particles, 5-12% of composite flame retardant, 1-3% of matting agent, 0.5-2% of composite light stabilizer, 0.1-0.5% of composite nucleating agent, 0.1-0.5% of anti-oxidant, and 0.1-1% of lubricant. The matting agent is in the form of a cross-linking type butadiene-acrylonitrile polymer or a cross-linking type styrene-acrylonitrile polymer. According to the invention, the original advantages of PET and PTT materials are realized, while the alloy has the high-fire-retardant, high-impact-grade, high-heat-resistance, high-strength and low-grass application effect at the same time. The alloy is good in machining performance and low in cost, thus being suitable for industrial production, deployment and application.
