Poly-terephthalic acid butanediol ester (PBT)/ poly-terephthaloyl hexamethylenediamine (PA6T) alloy material capable of enhancing inflaming retarding and production method thereof

Abstract

The invention relates to the field of organic polymer, in particular to a poly-terephthalic acid butanediol ester (PBT) / poly-terephthaloyl hexamethylenediamine (PA6T) alloy material capable of enhancing inflaming retarding and a production method thereof. PBT, PA6T, magnesium sulfate whisker, compatilizer, DBDPE, fire retardant antimonous oxide, fire retardant tripolycyanamide urate and antioxygen are adopted as raw materials and are dried, mixed, extruded and cut into particles so that the magnesium sulfate whisker inflaming retarding enhancing PBT / PA6T alloy material is produced. The PBT / PA6T alloy material capable of enhancing the inflaming retarding and the production method thereof are characterized in that weight percentage of composition of the raw materials comprises: the 40%-45% of PBT, the 5%-10% of PA6T, the 22%-30% of magnesium sulfate whisker, the 5%-8% of compatilizer, the 6%-10% of DBDPE, the 3%-5% of fire retardant antimonous oxide, the 3%-5% of fire retardant tripolycyanamide urate and the 0.3%-0.5% of antioxygen. The PBT / PA6T alloy material capable of enhancing the inflaming retarding and the production method thereof have the advantages that the magnesium sulfate whisker inflaming retarding enhancing PBT / PA6T alloy material produced is good in liquidity, high in glowing filament performance and mechanical property and simple in production technology.

Description

technical field [0001] The invention relates to the field of organic polymer materials, in particular magnesium sulfate whisker-reinforced, high-glow wire flame-retardant polybutylene terephthalate (PBT) / polyhexamethylene terephthalamide (PA6T) alloy Materials and their methods of production. Background technique [0002] We know that for many years, the flame retardant safety evaluation of electronic and electrical plastic materials or plastic parts has been based on the US UL94 that burns directly. However, in recent years, with the frequent occurrence of fire incidents caused by internal plastic parts catching fire during the use of household appliances, another flame retardant evaluation method of the European Union's International Electrotechnical Commission (IEC) - glow wire flame retardant test standard (IEC 60695) increasingly attracting attention. [0003] According to the standard of IEC 60695-2-12:2000, if the glow wire time is less than 30S, it is qualified. H...

AI Technical Summary

Problems solved by technology

After the traditional flame-retardant reinforced PBT raw materials are made into finished products, they can basically meet the test of vertical burning performance, but they do not perform well in the glow wire test. Therefore, PBT products that can meet both vertical burning performance and glow wire performance requirements are developed very necessary
