Embodiment 1

[0010] Embodiment 1 provides a green, environment-friendly, cold-resistant and flexible nylon 66 material, which consists of the following components by weight: nylon 66: 75.5%; nylon softener: 15%; compatibilizer: 8%; antioxidant: 1.0%; others Additives: 0.5%.

[0011] Dry nylon 66 first, then weigh it with nylon softener, compatibilizer, antioxidant and other additives according to the proportion, and then mix it in the mixer at low speed for 10 minutes. The wall gap is less than 0.5 cm, and the mixing effect of raw and auxiliary materials should be visually observed that the various particles, powders, and liquids are basically uniform, without obvious agglomerates or agglomerations; the twin-screw extruder uses a 40 aspect ratio and medium-strength shear; water-cooled pull bars are used The pelletizing method (or underwater pelletizing method), after sieving and dehydration, can produce green, environment-friendly, cold-resistant and flexible nylon 66 material.

Abstract

The invention relates to a process of a green environment-friendly flexible nylon 66 material. The green environment-friendly flexible nylon 66 material is composed of the following components in percentage by weight: 49.5-90% of nylon 66, 3-35% of nylon softener, 3-35% of compatibilizer, 0.3-1.5% of antioxidant and 0.3-5.5% of other assistants. According to the invention, the green environment-friendly anti-freezing flexible nylon 66 material can resist a low temperature of minus 40 degrees; the cantilever notch impact strength is almost 10 times higher in comparison with the common nylon 66; both the production and the procurement are convenient; and the raw materials, auxiliary materials and production equipment are all made in China. Thus, the competitive power is greatly improved.

Description

technical field [0001] The invention relates to an organic polymer composite material, and more specifically relates to a green and environment-friendly flexible nylon 66 material technology. The invention also relates to a method for making the green and environment-friendly flexible nylon 66 material. Background technique [0002] Nylon 66 is one of the most widely used engineering plastics. It has a high melting point, good physical and mechanical properties, wear resistance and self-lubricating properties. These comprehensive characteristics are not available in other plastics. However, the impact strength of pure nylon 66 is low, and this shortcoming is more prominent at lower ambient temperatures. The nylon 66 material used in films, sheets, pipes and rods in many places needs to have certain flexibility and grease resistance under the premise of maintaining the original tensile strength and temperature resistance of the nylon 66 material, and can It still maintains ...
