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 manufacture process of a cold-resistant flexible high temperature resisting nylon material. The cold-resistant flexible high temperature resisting nylon material is composed of the following components in percentage by weight: 49.5-90% of high temperature nylon, 1-10% of nylon 66, 3-35% of cold-resistant agent, 3-35% of softener, 1-10% of bulking agent, 0.3-1.5% of antioxidant, 0.3-3.5% of heat stabilizer and 0.3-5.5% of other auxiliaries. A green environmental-protection flexible nylon material disclosed by the invention can resist to a low temperature of -40 DEG C, cantilever notch impact strength is about ten times higher than that of common nylon, and moreover, the cold-resistant flexible high temperature resisting nylon material is convenient to produce and purchase, and competitive capacity is greatly improved.

Description

technical field [0001] The invention relates to an organic polymer composite material, and more specifically relates to a manufacturing process of a cold-resistant, flexible, and high-temperature-resistant nylon material. The invention also relates to a method for making the cold-resistant flexible 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 materials to produce these components. Th...
