The application belongs to the field of
engineering plastics, and particularly relates to long-chain
polyamide resin with easy
processing and high tensile property, and a preparation method and application thereof. The long-chain
polyamide resin comprises the following
raw material components: component a: aliphatic
carboxylic acid compound component; component b:
polyamine compound component; and component c: a compound with a structure shown in the following formula (1), wherein n and m can be any number between 1 and 10. The long-chain
polyamide resin of the application introduces structural diacid with an asymmetric
benzene ring structure, utilizes the asymmetric structure to reduce the
crystallinity of the material, and introduces the
benzene ring structure to improve the
mechanical property of the polyamide material, so that the low
processing temperature is realized from the polyamide material component itself, the
energy consumption is reduced, and the
mechanical property of the polyamide material is ensured. The problem that the
processing temperature and
mechanical property of the polyamide material and the processing
energy consumption are difficult to be considered in the prior art is solved.
