Abstract
The invention relates to a manufacturing process of a heat conduction nylon material. The heat conduction nylon material is composed of 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. According to the invention, the green environment-friendly heat conduction nylon material can be used instead of a metal raw material for the production of spare parts or shells, and simultaneously has higher physical and mechanical properties of the nylon as well as heat conduction and heat radiation functions and heat stability of the metal material; both the production and the procurement are convenient; and the relevant cost is greatly lowered. Thus, the competitive power is greatly improved.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly relate to a kind of heat-conduction nylon material manufacture craft, 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 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 certain heat conduction or heat sinking 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, and it is large to stand the process for processing difficulty, 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 makes the plastic raw materials alternative metals produce product and becomes a reality.It has excellent physical strength, good outward appearance.Complete processing by uniqueness, 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, 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, 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 namely has the higher physical and mechanical properties of nylon simultaneously, the heat conduction, heat sinking function and the thermal stability that have again simultaneously metal material, 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: first 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, added in proportion by the side in the screw combinations situation that some strength is sheared through twin screw extruder again, mixing extrusion, water cooling bracing pelletizing (or die face ring cutting) makes the 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 namely has the higher physical and mechanical properties of nylon simultaneously, the heat conduction, heat sinking function and the thermal stability that have 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 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 is made of by weight nylon following composition: 44%; Heat conducting fiber: 5%; Conductive powder: 45%; Lubricant: 4%; Coupling agent: 0.8%; Other auxiliary agents: 1.2%.
First 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 substantially even, 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 cooling bracing pelletizing mode, namely make the 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 to this; 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.
