Abstract
The invention relates to an organic polymer composite material, in particular to a process for producing electromagnetic polymer nylon 66 material. The electromagnetic polymer nylon 66 material comprises the following components by weight: 49.5-90% of nylon 66, 0-45% of metal fiber, 0-35% of carbon fiber, 0-30% of conductive graphite, 2-5% of heat stabilizer, 0.2-1.0% of coupling agent and 0.3-5.5% of other additives. The electromagnetic shielding polymer nylon 66 material can replace the metal raw materials, can be used for producing spare parts or shells, has the high physical and mechanical properties of nylon 66 and the electromagnetic shielding function of the metal material, is convenient to produce and purchase and has greatly reduced related cost and comprehensively improved competitiveness.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly relate to a kind of electromagnetism macromolecule nylon 66 material manufacture crafts.
Background technology
The application that at present substitutes the natural mineral raw metal with plastics in the world constantly enlarges, and scientist all over the world actively seeks new functional thermoplastics by various tests, also becomes enterprise and strives for more families and the important component part of extending volume growth.
But the electroconductibility of metal material and capability of electromagnetic shielding are that common plastics is not available.And at present in civil electronic electrical equipment/toy/communication/cable/many fields such as military project, all relate to the part that need to have electro-magnetic screen function, needing simultaneously has higher physical strength, and certain temperature resistant capability is arranged again.This series product market substantially all has to use raw material metal production at present, is standing the process for processing difficulty large, and link is many, and cost is high, a series of shortcomings that production efficiency is low etc.These are the problem to be solved in the present invention just.
The invention of nylon 66 makes the plastic raw materials alternative metals produce product and becomes a reality.It has excellent physical strength, good outward appearance, and higher thermotolerance, in engineering plastics commonly used, it is best a kind of of over-all properties.Complete processing by uniqueness, add related component, under the associated advantages prerequisite that keeps nylon 66, give the function of its electromagnetic shielding, thereby at the more multi-field raw metal that substituted, so that the technology of related products is not subjected to the restriction of the conditions such as raw-material processing and production/cost, the development of being jumped.
Series product of the present invention fully meet European Union's " waste and old electric electric installation " (WEEE) and " objectionable impurities limits the use of instruction " (RoHS) rules and other environmental regulations, and strict Application Areas can both be used.
Summary of the invention
The object of the invention is to effectively overcome the defective of prior art, a kind of electromagnetic shielding nylon 66 material of can the alternative metals starting material producing spare and accessory parts or shell is provided.
Technical scheme provided by the invention is as follows: electromagnetic shielding nylon 66 material forms nylon 66:49.5-90% by following composition, steel fiber: 0-45% by weight; Carbon fiber: 0-35%, electrically conductive graphite: 0-30%; Thermo-stabilizer: 2-5%; Coupling agent: 0.2-1.0%; Other auxiliary agents: 0.3-5.5%.
The preparation method of electromagnetic shielding nylon 66 material of the present invention, comprise the steps, first with nylon 66, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, in proportion add steel fiber and carbon fiber and electrically conductive graphite mixing extrusion by the side through twin screw extruder in the screw combinations situation that medium tenacity is sheared again, the water cooling bracing pelletizing makes electromagnetic shielding nylon 66 material through screening and dewatering.
The present invention has effectively overcome the defective of existing nylon material, has the following advantages:
A kind of electromagnetic shielding nylon 66 material of the present invention can be produced spare and accessory parts or shell by the alternative metals starting material, he namely has the higher physical and mechanical properties of nylon 66 simultaneously, the electro-magnetic screen function that has again simultaneously metal material, thereby production procurement is convenient, relevant cost declines to a great extent, comprehensive like this competitive power that improved.
Embodiment
Below be the most preferred embodiment of electromagnetic shielding nylon 66 raw material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of electromagnetic shielding nylon 66 raw material is provided, and is made of by weight nylon 66:63% following composition; Steel fiber: 10%; Carbon fiber: 10%; Electrically conductive graphite: 13%; Thermo-stabilizer: 2%; Coupling agent: 0.8%; Other auxiliary agents: 1.2%;
First with nylon 66, thermo-stabilizer, coupling agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, mixer adopts low speed mixing, paddle should with the barrel gap less than 0.5 centimetre, the supplementary material mixed effect should visual various particles and powder substantially even, do not have obvious agglomerate or gather; Twin screw extruder uses 36 length-to-diameter ratios, and medium tenacity is sheared; Steel fiber/carbon fiber and electrically conductive graphite are added in proportion by the side; Adopt water cooling bracing pelletizing mode, namely make electromagnetic shielding nylon 66 material through screening and dewatering.
