Abstract

The invention relates to a low-temperature-resistant flexible nylon material preparation method, and belongs to the technical field of new materials. According to the invention, a silane coupling agent is used as a polymer surface treatment agent, such that the long-term weather resistance, the water resistance and the chemical corrosion resistance of the prepared low-temperature-resistant flexible nylon material are improved; by using polyurethane as an elastomer to toughen the low-temperature-resistant flexible nylon material, when the material is impacted, the toughener elastomer particlesas the stress concentration center can induce a large amount of crazes and shear zones, the toughener elastomer particles can further control the development of the crazes and terminate the crazes soas not to cause the generation of destructive cracks, and the stress field occurring at the front edge of the craze can induce the formation of the shear zone while the shear zone can slow the growthof the craze, such that the development of the craze and the shear zone consumes a lot of energy during the change so as to significantly improve the impact strength of the composite material.

Description

technical field [0001] The invention relates to a preparation method of a low-temperature-resistant flexible nylon material, which belongs to the technical field of new materials. 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. There is also a trend to replace metal and thermoset materials with high-temperature resistant plastics for devices and components of new equipment. All of these wil...
