Embodiment 1

[0009] Embodiment 1 provides an electromagnetic shielding nylon 6 raw material, which is composed of the following components by weight ratio, nylon 6: 65%, halogen-free and alkali-free glass fiber: 10.5%; thermosetting resin: 7.5%; conductive graphite: 12%; Stabilizer: 3%; filler: 1.0%; activated carbon: 1%.

[0010] Make nylon 6 into an aqueous solution of about 30%, add it to the reaction kettle, slowly add a certain proportion of halogen-free and alkali-free glass fiber, thermosetting resin, conductive graphite, heat stabilizer, Filling material, in addition, after the reaction is completed, purify and filter with activated carbon to obtain a 50% nylon 6 salt solution. The salt-forming reaction is an exothermic reaction, so the heat of reaction must be removed by cooling the circulating water, and at the same time, in order to prevent the nylon 6 salt from being oxidized in contact with air, the production system is filled with nitrogen protection. Under vacuum, the 50% n...

Abstract

The invention relates to an organic high-molecular composite material, and specifically relates to nylon 6 with an electromagnetic screening function. The material comprises components of, by weight: 49.5 to 90% of nylon 6, 10 to 45% of halogen-free alkali-free glass fiber, 5 to 15% of thermoset resin, 2 to 30% of conductive graphite, 2 to 5% of a thermal stabilizer, 0.2 to 1.0% of a filling material, and 0.3 to 5.5% of active carbon. The nylon 6 with the electromagnetic screening function is advantaged in that: the nylon 6 can be used for replacing metal materials for producing replacement parts or housings; the nylon 6 has both high mechanical properties of nylon 6 and the electromagnetic screening function of metal materials; and the nylon 6 is convenient to produce and purchase, and related costs are greatly reduced. Therefore, competitive strength of the nylon 6 with the electromagnetic screening function is comprehensively improved.

Description

technical field [0001] The invention relates to a nylon 6 with electromagnetic shielding. Background technique [0002] Shielding is the isolation of metal between two spatial regions to control the induction and radiation of electric fields, magnetic fields and electromagnetic waves from one region to another. Specifically, it is to surround the interference source of components, circuits, assemblies, cables or the whole system with a shield to prevent the interference electromagnetic field from spreading outward; to surround the receiving circuit, equipment or system with a shield to prevent them from being affected by the outside world. The influence of electromagnetic fields. Because the shield absorbs energy (eddy current loss), reflects energy (interface reflection of electromagnetic waves on the shield) and counteracts energy (electrical Magnetic induction generates a reverse electromagnetic field on the shielding layer, which can offset part of the effect of interf...
