Abstract
The invention relates to an organic polymer composite material, in particular to a technology for manufacturing an electromagnetic organic shielding polypropylene material; and the material comprises the components by weight percent: 49.5-90% of polypropylene, 5-35% of carbon fiber, 2-30% of electric conduction graphite, 0.2-1.0% of antioxidant, 0.2-2.0% of coupling agent and 0.3-5.5% of other auxiliary agents. The electromagnetic organic shielding polypropylene material can be used for replacing metal raw materials and producing parts or shells, and has good convenient processing performance of thermoplastic plastics and the electromagnetic shielding function of the metal material, thus being convenient in production and purchase and greatly reducing the related cost; meanwhile, the material also has the characteristic of acid-base corrosion resistance and a certain mechanical strength and temperature endurance, so that the competitiveness is comprehensively improved.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of electromagnetism organic screen polypropylene material manufacture craft.
Background technology
At present, the application with the plastics alternative metals constantly enlarges in the world, 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 and capability of electromagnetic shielding are that common plastics are 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.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.Without the need for higher heatproof requirement, have simultaneously when requiring in certain intensity and heatproof and work-ing life, can use and of the present inventionly have the electro-magnetic screen function polypropylene and carry out injection moulding or extrusion as starting material, the cost decrease, the raising of production efficiency several times contributes for the lightweight of product and returnability simultaneously; Also has advantages of simultaneously the not available acid-alkali-corrosive-resisting of raw material metal.
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 just be used.
Summary of the invention
The object of the invention is to effectively overcome the defective of prior art, a kind of environmental protection electromagnetic shielding polypropylene starting material of can the alternative metals starting material producing spare and accessory parts or shell are provided.
Technical scheme provided by the invention is as follows: electromagnetic shielding polypropylene material is made of polypropylene (powder and pellet all can): 49.5-90%, carbon fiber: 5-35% by weight following composition; Electrically conductive graphite: 2-30%; Antioxidant: 0.2-1.0%; Coupling agent: 0.2-2.0%; Other auxiliary agents: 0.3-5.5%.
The preparation method of electromagnetic shielding polypropylene material of the present invention; comprise the steps: first with polypropylene, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes; in proportion add 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, water cooling bracing pelletizing (die face cutting or water ring pelletizing all can) makes the anti-polypropylene material of electromagnetic shielding through screening and dewatering.
The present invention has effectively overcome the defective of existing polypropylene material, has the following advantages:
A kind of electromagnetic shielding polypropylene material of the present invention can be produced spare and accessory parts or shell by the alternative metals starting material, he namely have simultaneously thermoplastics good be convenient to processing characteristics, the electro-magnetic screen function that has again simultaneously metal material, thereby production procurement is convenient, relevant cost declines to a great extent, also have simultaneously the characteristics of acid-alkali-corrosive-resisting and certain physical strength and temperature tolerance, comprehensive like this competitive power that improved.
Embodiment
Below be the most preferred embodiment of electromagnetic shielding polypropylene raw material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of electromagnetic shielding polypropylene raw material is provided, and is made of by weight polypropylene following composition: 65%; Carbon fiber: 25%; Electrically conductive graphite: 8%; Oxidation inhibitor: 1%; Coupling agent: 0.5%; Other auxiliary agents: 0.5%;
First with polypropylene, oxidation inhibitor, 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; Carbon fiber and electrically conductive graphite are added in proportion by the side; Adopt water cooling bracing pelletizing mode, namely make the environmental protection electromagnetic shielding polypropylene material through screening and dewatering.
