Abstract
Plastic industry is developed so far because it has high corrosion resistance and insulating properties, so as to instead of conventional metals in some fields, polyamide 6 (PA6) engineering plastics have excellent mechanical property and electrical property, also have the advantages that wear-resisting, oil resistant, self-lubricating, corrosion-resistant and good processing characteristics；Also more and more extensively, range of application is including automobile, plant equipment, electronic apparatus, chemical industry equipment, building, daily necessities, communications and transportation etc. for its purposes.The present invention provides a kind of mechanical property for not influenceing material, enhances the material modified preparation method of the polyamide heat-conducting of polyamide material heat conductivility.
Description
Technical field
The invention belongs to polyamide PA6 material production technologies, specifically a kind of polyamide heat-conducting is material modified
And preparation method thereof.
Background technology
Plastic industry is developed so far because it has high corrosion resistance and insulating properties, so as to be substituted in some fields
Conventional metals, polyamide 6 (PA6) engineering plastics have excellent mechanical property and electrical property, also with it is wear-resisting,
The advantages of oil resistant, self-lubricating, corrosion-resistant and good processing characteristics；Its purposes is also more and more extensive, using model
Enclose including automobile, plant equipment, electronic apparatus, chemical industry equipment, building, daily necessities, communications and transportation etc..
The content of the invention
It is material modified and preparation method thereof it is an object of the invention to provide a kind of polyamide heat-conducting.
The material modified raw material of polyamide heat-conducting matches and is by mass percentage：Polyamide PA6：50th, magnesia (10-12um)：
50th, antioxidant (copolymer of ethylene-octene)：1.5th, colouring agent：1.0th, dispersed lubricant (TAS-2A)：1.0.
The material modified preparation method of the polyamide heat-conducting is：Various raw materials are dry-mixed 15-20 minutes in super mixer, then
It is placed in double screw extruder through melting extrusion, cooling, pelletizing, packed products；Wherein, the area's temperature of double screw extruder one
It is 160-180 DEG C to spend, and 2nd area are 230-250 DEG C, and 3rd area are 255-275 DEG C, and 4th area are 250-270 DEG C；5th area are 230-250
DEG C, the residence time is 1-2 minutes, and pressure is 10-15Mpa.
Specific embodiment
Embodiment
(1) the material modified raw material of the polyamide heat-conducting matches and is by mass percentage：Polyamide PA6：50th, magnesia
