Abstract
The invention discloses polyethylene plastic with excellent heat conductivity, which significantly increases the heat conductivity of HDPE material through modifying high density polyethylene (HDPE) material with heat conductivity ceramic material. The proportion (weight ratio) of material is that 100 parts of high density polyethylene (HDPE), 45-55 parts of silicon carbide (SiC), 5-15 parts of ethylene-vinyl acetate copolymer (EVA) and 3-8 parts of lubricating agent (PE wax). Heat conductivity ceramic material silicon carbide powder is added in high density polyethylene, thereby increasing the heat conductivity of material, simultaneously ethylene-vinyl acetate copolymer is added, which increases shock resistance.
Description
Technical field
The present invention relates to vinyon, particularly a kind of polyethylene with high thermal conductivity.
Background technology
Vinyon is because corrosion-resistant, ageing-resistant, good impact resistance are widely used in manufacturing pipeline, tubing.Some pipeline, achieves the goal by underground heat and ducted medium energy exchange as the underground pipeline of geothermal space conditioning in order to heat exchange, needs thermal conductivity good.But polythene material is the poor conductor of heat, and the common polythene material is in the utilization process, and heat transfer efficiency is low, needs to reduce pipeline wall thickness, causes intensity to reduce like this, perhaps increases length, the surface-area of pipeline, has increased cost.
Summary of the invention
The polyethylene that provides a kind of thermal conductivity good is provided the object of the invention, in order to make pipeline, is beneficial to use.
The present invention adopts the thermal conductive ceramic material that low pressure polyethylene (HDPE) material is carried out modification, and the thermal conductivity of HDPE material is significantly improved.Material mixture ratio of the present invention (weight ratio) is:
Low pressure polyethylene (HDPE): 100 parts
Silicon carbide (SiC): 45-55 part
Ethene-vinyl acetate copolymer (EVA): 5-15 part
Lubricant (PE wax): 3-8 part
Advantage of the present invention is: owing to added thermal conductive ceramic material silicon carbide powder in low pressure polyethylene, improved the thermal conductivity of material, added ethene-vinyl acetate copolymer simultaneously, improved shock resistance.
Embodiment
The invention will be further described according to embodiment below.
Each material mixture ratio that embodiment adopts is (weight ratio):
Low pressure polyethylene (HDPE): 100 parts
Silicon carbide (SiC): 50 parts
Ethene-vinyl acetate copolymer (EVA): 10 parts
Lubricant (PE wax): 5 parts
During manufacturing, the material of above-mentioned prescription is mixed by high-speed mixer, with the dual-screw pelletizer granulation, again through the single screw extrusion machine extruding pipe material.
Tubing heat conductivility after this modification reaches 0.5656W/mk, and more common HDPE tubing 0.4123W/mk is significantly increased.
Polyethylene pipe after the employing modification is applied in the geothermal air conditioning system, and the outer rate of energy transfer of medium in the pipeline and pipeline has improved 10%, provides cost savings, and has improved efficient.
