Abstract

The invention provides a polyamide composition as well as a preparation method and application thereof. The polyamide composition comprises the following components: polyamide resin, polyethylene naphthalate (PEN) resin, a reinforcing phase, a modified molecular sieve, polyquaternium and an auxiliary agent, the modified molecular sieve is a gold bromide modified molecular sieve. According to the polyamide composition, the PA is blended with the PEN resin, and the gold bromide modified molecular sieve and the polyquaternium are added, so that the ion barrier property and the gas barrier property of the polyamide composition can be improved, the volatility of small molecular substances in the composition is reduced, the small molecular substances are not easy to desorb, the precipitation of impurities is effectively reduced, and the service life of the composition is prolonged. In addition, by adding the polyquaternium, impurity ions such as sulfate ions in a resin system are fully reacted, and ion precipitation is reduced. The polyamide composition disclosed by the invention has the advantages of low impurity, low ion precipitation and low TVOC (Total Volatile Organic Compound).

Description

technical field [0001] The present invention relates to the technical field of polymer materials, and more particularly, to a polyamide composition and a preparation method and application thereof. Background technique [0002] For the automotive industry, fuel cells powered by hydrogen energy have become a popular direction. Among them, the hydrogen fuel cell assembly generally includes a reactor stack, a hydrogen supply system, an air intake and exhaust system, a thermal management system, and a hydrogen storage tank. For the sake of light weight, polyamide material solutions are mostly used for hydrogen supply system and air intake and exhaust system components, such as hydrogen supply valve, ejector, water-air separator, joint, air filter, intake pipeline, middle Coolers, humidifiers, manifolds. Such components either deliver hydrogen or oxygen to the stack. During the electrochemical reaction, some impurity ions and gases will be adsorbed on the surface of the cataly...
