Problems solved by technology

[0005] However, all types of high-temperature-resistant plastic materials currently on the market have a common disadvantage: low impact and obvious brittleness, especially in sub-zero low temperature environments, they are more brittle
This disadvantage greatly limits the application range of high temperature plastics to replace metal and wood

Embodiment 1

[0012] Embodiment 1 provides a green, environmentally friendly, cold-resistant, flexible and high-temperature-resistant nylon material, which is composed of the following components by weight: high-temperature nylon: 60%; nylon 66: 7%; cold-resistant agent: 7%; softener: 15%; Antioxidant: 8%; Antioxidant: 1.0%; Heat stabilizer: 1.5%; Other additives: 0.5%;

[0013] First, weigh high-temperature nylon, nylon 66, cold-resistant agent, softener, compatibilizer, antioxidant, heat stabilizer, and other additives according to the proportion and mix them in the mixer at low speed for 10 minutes. The mixer adopts low-speed mixing, The gap between the mixing blade and the cylinder wall should be less than 0.5 cm, and the mixing effect of raw and auxiliary materials should be visually observed that the various particles and powders are basically uniform, without obvious agglomeration or agglomeration; the twin-screw extruder uses a combination of 42 length-to-diameter ratios and medium-s...

Abstract

The invention relates to a green, environment-friendly and flexible nylon material for resisting cold and high temperature, comprising the components in percentage by weight: 49.5-90 percent of high-temperature nylon, 1-10 percent of nylon 66, 3-35 percent of cold-resistant agent, 3-35 percent of softener, 1-10 percent of bulking agent, 0.3-1.5 percent of antioxidant, 0.3-3.5 percent of thermal stabilizer and 0.3-5.5 percent of other assistants. The green, environment-friendly and flexible nylon material for resisting cold and high temperature can resist the low temperature of -40DEG C; the impact strength of a cantilever beam notch is near ten times higher than that the general high-temperature nylon; and the material is convenient to produce and purchase, so that 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, flexible and high-temperature-resistant nylon material. The invention also relates to a method for making the green, environment-friendly, cold-resistant, flexible and high-temperature-resistant nylon material. Background technique [0002] At present, the application of replacing natural materials with plastics continues to expand internationally. Scientists around the world are actively looking for new high-performance thermoplastics to replace metal and wood through various experiments. important parts of. [0003] The development of high-temperature plastics has made it possible for industrial, agricultural and civil facilities to be miniaturized, lightweight and powerful. High-temperature-resistant plastics can bring higher temperature resistance to certain components, or simply replace metal raw materia...
