Abstract

The invention discloses a nylon alloy plastic pipe and a preparation technology thereof. The nylon alloy plastic pipe is prepared from PA66, PA610, PA1010, PA12, a fire retardant, a lubricant, a waterproof agent and an antioxidant. The preparation technology comprises the steps that raw material resin is weighed accurately, and then drying treatment is performed; the dried raw material resin is subjected to mixing, the fire retardant, the lubricant, the waterproof agent and the antioxidant are added to obtain a mixed melt; the mixed melt is extruded from a hopper, molded at a machine head mouth mold to obtain a continuous body and extruded out of a machine through a screw, and cooling, sizing, traction and stretching are performed to obtain the nylon alloy plastic pipe. The prepared nylon alloy plastic pipe has the excellent water resistance, shrinking resistance, lubricating property, high pressure bearing capacity and thermal stability.

Description

technical field [0001] The invention relates to the field of polyamide compositions, in particular to a nylon alloy plastic pipe and a preparation process thereof. Background technique [0002] Nylon (PA), also known as polyamide, is a general term for thermoplastic resins containing repeated amide groups—[NHCO]—in the main chain of the molecule, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Plastic pipes made of nylon materials have excellent wear resistance, heat resistance, mechanical strength, elasticity, toughness and bending fatigue resistance. However, due to the characteristics of the molecular structure of polyamide, it has strong hydrophilicity and high water vapor sensitivity. It must be dried before application, which limits the application range of nylon pipes, and the shrinkage of nylon materials is large. , the lubricating performance is poor, the ability to withstand high pressure is low, and the thermal stability is poor. If the nylon pipe ...
