Abstract
The invention aims to provide a material for improving the heat-conducting property of a polyamide (PA) 6 material, and a preparation method of the material. With the development of the polyamide plastic industry, the polyamide plastic, due to its high corrosion resistance and insulating property, has replaced traditional metals in certain fields; the polyamide 6 (PA6) engineering plastic has good mechanical properties and electrical properties and also has the advantages of wear resistance, oil resistance, self-lubricating property, corrosion resistance and good processability and the like; and the PA6 engineering plastic is applied more and more widely, and the scope of application comprises automobiles, mechanical equipment, electronic electric appliances, chemical equipment, construction, articles for daily use, transportation and the like. The mechanical properties of the PA6 material obtained by the method provided by the invention can reach a use standard, and moreover, the heat-conducting property of the polyamide material is improved.
Description
Technical field
The invention belongs to polymeric amide PA6 material produce technology, improve the deficiency of original material, produce the product meeting need of social production.
Background technology
Plastic industry is developed so far because it has high corrosion resistance and insulativity, thus conventional metals is instead of in some fields, polyamide 6 (PA6) engineering plastics have excellent mechanical property and electrical property, also have the advantages such as wear-resisting, oil resistant, self-lubricating, corrosion-resistant and good processing characteristics; Its purposes is also more and more extensive, and range of application comprises automobile, mechanical means, electronic apparatus, chemical industry equipment, building, daily necessities, communications and transportation etc.
Summary of the invention
The object of this invention is to provide a kind of mechanical property not affecting material, improve the method for material property.
This polymeric amide PA6 thermally conductive material is made up of following weight ratio raw material:
