Problems solved by technology

However, these components will generate a lot of heat when they are in operation. If the heat is not transferred out in time, the life of the components will be greatly shortened.
However, the thermal conductivity of plastics has always been considered low, and its thermal conductivity is between 0.1 and 0.5W / mK.

[0029] Comparative example 1 preparation method comprises the steps:

[0030] According to Table 1, add the weighed PP, PE, PET, compatibilizer and other additives into the high-speed mixer and mix for 2 minutes, so that the components are fully stirred and dispersed evenly, and then the mixed materials are added to the twin-screw In the extruder, the processing technology is: the temperature of the first zone is 245±5°C, the temperature of the second zone is 250±5°C, the temperature of the third zone is 260±5°C, the temperature of the fourth zone is 245±5°C, the temperature of the fifth zone is 240±5°C, the extruder The head temperature is 250±5°C, and the screw host speed is 350-400 rpm.

Embodiment 1～6

[0031] Embodiment 1~6 preparation method comprises the steps:

[0032] MgO (or Al 2 o 3 ) were baked at 105±5°C for 3 hours, and the moisture content was controlled below 0.1%; and the MgO (or Al 2 o 3 ) of the mass of 1% of the coupling agent is sprayed in, heated and stirred for 20 minutes, taken out and baked at 105±5°C for 4 hours, sealed and stored for later use;

[0033] According to Table 1, add the weighed PP, PE, PET, compatibilizer and other additives, heat conduction agent system, light stabilizer and other additives into the high-speed mixer and mix for 2 minutes, so that the components are fully stirred Disperse evenly. Then put the mixed material into the twin-screw extruder. The processing technology is: the temperature of the first zone is 245±5°C, the temperature of the second zone is 250±5°C, the temperature of the third zone is 260±5°C, the temperature of the fourth zone is 245±5°C, The temperature in the fifth zone is 240±5°C, the temperature of the ma...

Abstract

The invention discloses a weatherproof thermal-conductive PP-PE-PET composite material and a preparation method thereof. The main points of the technical scheme comprise that the composite material iscomposed of the following components by the weight percentage: 26-44.5% of PP resin, 5-10% of PE resin, 8-15% of PET resin, 3-6% of a compatibilizer, 30-50% of a thermal-conductive agent system, 0.5-1.5% of a light stabilizer, and 0.5-2.5% of other auxiliary agents. The weatherproof thermal-conductive PP-PE-PET composite material meets new technical requirements and has good weatherability and thermal conductivity.

Description

【Technical field】 [0001] The invention relates to the technical field of polymers, in particular to a weather-resistant and heat-conducting PP-PE-PET composite material and a preparation method thereof. 【Background technique】 [0002] At present, plastics are widely used in electronic components, LED lighting, radiators, integrated circuits and other fields. However, these components will generate a lot of heat during operation. If the heat is not transferred out in time, the life of the components will be greatly shortened. However, the thermal conductivity of plastics has been considered low, and its thermal conductivity is between 0.1 and 0.5W / mK. Therefore, there is an urgent need to prepare high thermal conductivity polymer composites with excellent comprehensive properties. 【Content of invention】 [0003] The weather-resistant and heat-conducting PP-PE-PET composite material of the invention meets new technical requirements and has good weather-resistant and heat-c...
