Embodiment 1

[0016] The polyolefin uses PE-RT, 100 parts, the heat transfer agent uses graphite, 30 parts, the compatibilizer uses PE grafted maleic anhydride 5 parts, the coupling agent uses titanate coupling agent 1.5 parts, and the lubricant uses white oil 3 copies.

[0017] Material mixing method: Add graphite dried at 100°C for two hours into the high-speed mixer, then gradually add the coupling agent solution diluted with white oil into the high-speed mixer, and stir for 5 minutes. Then add the measured amount of PE-RT resin and compatibilizer, and stir at high speed for five minutes. The mixed raw materials are extruded and granulated through a twin-screw extruder, and the material temperature of the extruder is controlled between 128-178°C.

Embodiment 2

[0019] 100 parts of PP-R is used for polyolefin, 30 parts of graphite is used as heat transfer agent, 5 parts of PP grafted maleic anhydride is used as compatibilizer, 1.5 parts of titanate coupling agent is used as coupling agent, and white oil is used as lubricant 3 copies. The material mixing method is the same as in Example 1, but the difference from Example 1 is that the material temperature of the extruder is controlled between 185-220°C.

Embodiment 3

[0021] The polyolefin uses PP-R, 100 parts, the heat transfer agent uses aluminum oxide, 100 parts, the compatibilizer uses 50 parts of PP grafted maleic anhydride, the coupling agent uses 2.5 parts of titanate coupling agent, and the lubricant uses white Oil 5 parts. The material mixing method is the same as in Example 1, but the difference from Example 1 is that the material temperature of the extruder is controlled between 185-220°C.

Abstract

The invention relates to a formula of a multi-component plastic material for preparing a plastic pipeline with high thermal conductivity. The material comprises the following components in part by weight: 100 parts of polyolefin, 10 to 200 parts of heat transfer agent, 1 to 100 parts of compatilizer, 0.5 to 5 parts of lubricant and 0.5 to 10 parts of coupling agent. The plastic pipeline made of the material of the invention has the advantages of high heat conduction coefficient, capability of meeting the using requirement of a product, convenient processing, low cost and suitability for popularization and application.

Description

technical field [0001] The invention belongs to the field of manufacturing high thermal conductivity plastic pipes, in particular to a material for preparing high thermal conductivity plastic pipes. Background technique [0002] Compared with metal and concrete pipes, plastic pipes have many advantages such as light weight, corrosion resistance, sanitation and safety, small water flow resistance, long service life, and convenient installation. my country's plastic pipe industry is a product system represented by PVC plastic pipes and polyolefin plastic pipes. Polyolefin plastic pipes (PE, PP, PB) are the largest type of plastic pipe products. Due to their good product performance, they have a wide range of applications in industries including construction, municipal engineering, agriculture, industry, electric power, and communications. application. [0003] In recent years, with the continuous progress of polyolefin resin synthesis technology and composite material modifi...
