Problems solved by technology

[0003] At present, in the market, the prices of related products of large foreign companies are extremely high, while the products of domestic manufacturers have sacrificed some of the advantages of nylon 6 itself, or due to insufficient craftsmanship or technology, the stability of product quality is not well controlled, and the scale cannot be achieved. production use

Embodiment 1

[0010] Embodiment 1 provides a green, environment-friendly, cold-resistant and flexible nylon 6 material, which is composed of the following components by weight: nylon 6: 78.5%; nylon softener: 12%; compatibilizer: 8%; antioxidant: 1.0%; others Additives: 0.5%.

[0011] Dry nylon 6 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 environmental protection cold-resistant flexible nylon 6 material.

Abstract

The invention relates to a green, environmentally-friendly, cold-resistant and flexible nylon 6 material, which consists of the following components in percentage by weight: 49.5 to 90 percent of nylon6, 3 to 35 percent of nylon softener, 3 to 35 percent of bulking agent, 0.3 to 1.5 percent of antioxygen and 0.3 to 5.5 percent of other additive. The green, environmentally-friendly, cold-resistant and flexible nylon 6 material of the invention can tolerate the low temperature of 40 DEG C below zero, has a cantilever beam gap impact strength which is about 10 times higher than that of the common nylon 6. In addition, the production and purchase are convenient, and raw and auxiliary materials and production equipment are China-made, so the competitiveness is greatly improved.

Description

technical field [0001] The invention relates to an organic polymer composite material, and more specifically relates to a green, environment-friendly, cold-resistant and flexible nylon 6 material. The invention also relates to a method for making the green, environment-friendly, cold-resistant and flexible nylon 6 material. Background technique [0002] Nylon 6 is a polyamide resin, one of the most widely used engineering plastics. Its amide group is polar and has a strong hydrogen bond in its structure, which makes nylon 6 have a high melting point and good Excellent 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 6 is low, and this shortcoming is more prominent at lower ambient temperatures. The nylon 6 material used in films and pipes in many places needs to have certain flexibility and grease resistance under the premi...
