Abstract
The invention relates to an environmental-friendly heat-conduction nylon material which comprises the following components in percentage by weight: 5-70% of nylon, 3-45% of heat-conduction fiber, 20-70% of heat-conduction powder, 2-5% of lubricant, 0.2-1.0% of coupling agent and 0. 3-5.5% of other assistants. The environmental-friendly heat-conduction nylon material can be used to replace metal raw materials to produce spare parts or shells and has the higher physical and mechanical properties of nylon and heat conduction and radiation function and thermal stability of metal materials simultaneously, can be produced and purchased conveniently with greatly reduced relative cost, thereby the competitiveness is improved comprehensively.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of environmental protection heat conduction nylon material, the invention still further relates to the method for making this heat conduction nylon material.
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 thermal conductivity of metal is that common plastics is not available.And, all relate to the part that need have certain heat conduction or heat sinking function at present in civil electronic electrical equipment/toy/communication/cable/many fields such as military project, and need higher physical strength simultaneously, certain temperature resistant capability is arranged again.This series product market substantially all has to use raw material metal production at present, and it is big to stand the process for processing difficulty, and link is many, cost height, a series of shortcomings that production efficiency is low or the like.These are the problem to be solved in the present invention just.
The invention of nylon makes the plastic raw materials alternative metals produce product and becomes a reality.It has excellent physical strength, good surface appearance.Pass through unique processing process, add related component, under the associated advantages prerequisite that keeps nylon, give the function of its heat conduction, heat radiation, thereby at the more multi-field raw metal that substituted, make the technology of related products be not subjected to the restriction of 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 objective of the invention is to, a kind of environmental protection heat conduction nylon material is provided, can produce spare and accessory parts or shell by the alternative metals starting material, he promptly has the higher physical and mechanical properties of nylon simultaneously, the heat conduction, heat sinking function and the thermal stability that have simultaneously metal material again, thereby production procurement is convenient, and relevant cost declines to a great extent, comprehensive like this competitive power that improved.
Technical scheme provided by the invention is as follows, nylon: 5-70%, heat conducting fiber: 3-45%; Conductive powder: 20-70%; Lubricant: 2-5%; Coupling agent: 0.2-1.0%; Other auxiliary agents: 0.3-5.5%;
The preparation method of environmental protection heat conduction nylon material of the present invention, comprise the steps: earlier with nylon, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, add at main spout through twin screw extruder; Conductive powder and heat conducting fiber, lubricant also in proportion after the weighing high-speed mixer and mixing 3 minutes, add in proportion by the side under the screw combinations situation that certain intensity is sheared through twin screw extruder again, mixing extruding, water-cooled tie rod pelletizing (or die face ring cutting) makes environmental protection heat conduction nylon material through screening and dewatering.
Environmental protection heat conduction nylon material of the present invention can be produced spare and accessory parts or shell by the alternative metals starting material, he promptly has the higher physical and mechanical properties of nylon simultaneously, the heat conduction, heat sinking function and the thermal stability that have simultaneously metal material again, 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 environmental protection heat conduction nylon material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of environmental protection heat conduction nylon material is provided, and forms nylon by weight by following composition: 44%; Heat conducting fiber: 5%; Conductive powder: 45%; Lubricant: 4%; Coupling agent: 0.8%; Other auxiliary agents: 1.2%.
Earlier with nylon, coupling agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, conductive powder and heat conducting fiber, lubricant also in proportion after the weighing high-speed mixer and mixing 3 minutes, the supplementary material mixed effect should visual various particles and powder even substantially, do not have obvious agglomerate or gather; Twin screw extruder uses 36 length-to-diameter ratios, and medium tenacity is sheared; Conductive powder and heat conducting fiber, lubricant are added in proportion by the side; Adopt water-cooled tie rod pelletizing mode, promptly make environmental protection heat conduction nylon material through screening and dewatering.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
