Embodiment 1

[0134] Example 1 (Ex 1)

[0135] Mix 3.2g of NPEL 128, 0.8g of HELOXY TM Modifier 48 and Hypox 2g TM RA840 was added to Speedmixer DC600 and mixed at 2000rpm for 2 minutes. Then, 4.6g of BAK-5 and 0.1g of R974 was added to the mixer and mixed for 3 minutes at 2000 rpm. Next, 18.4 g of BAK-20 was added to the mixer and mixed at 2000 rpm for 3 minutes. The mixture thus obtained was mixed under vacuum at 2000 rpm for 2 minutes. Then, 0.1 g of DMP 30 and 3.54 g of MHHPA were added to the mixture and mixed. Afterwards, the composition thus obtained is placed in a container for curing.

Embodiment 2

[0136] Example 2 (Ex 2)

[0137] 3.2g of NPEL 128, 0.8g of HELOXY TM Kane Ace with Modifier 48 and 2g TM MX267 was added to Speedmixer DC600 and mixed at 2000rpm for 2 minutes. Then, 4.6g of BAK-5 and 0.1g of R974 was added to the mixer and mixed for 3 minutes at 2000 rpm. Next, 18.4 g of BAK-20 was added to the mixer and mixed at 2000 rpm for 3 minutes. The mixture thus obtained was mixed under vacuum at 2000 rpm for 2 minutes. Then, 0.1 g of DMP 30 and 3.74 g of MHHPA were added to the mixture and mixed. Afterwards, the composition thus obtained is placed in a container for curing.

Embodiment 3

[0138] Example 3 (Ex 3)

[0139] Mix 3.2g of NPEL 128, 0.8g of HELOXY TM Modifier 48 and Hypox 2g TM RA840 was added to Speedmixer DC600 and mixed at 2000rpm for 2 minutes. Then, 4.6g of BAK-5 and 0.1g of R974 was added to the mixer and mixed for 3 minutes at 2000 rpm. Next, 18.4 g of BAH-20H4 was added to the mixer and mixed at 2000 rpm for 3 minutes. The mixture thus obtained was mixed under vacuum at 2000 rpm for 2 minutes. Then, 0.1 g of DMP 30 and 3.54 g of MHHPA were added to the mixture and mixed. Afterwards, the composition thus obtained is placed in a container for curing.

Abstract

This invention relates to a thermal conductive potting composition. In particular, the present invention relates to a thermal conductive potting composition having a low viscosity, a high thermal conductivity, a high toughness and excellent thermal shock performance for new energy vehicles.

Description

technical field [0001] The invention relates to a thermally conductive packaging composition. In particular, the present invention relates to a thermally conductive packaging composition for new energy vehicles having low viscosity, high thermal conductivity, high toughness (ie, excellent bond strength), and excellent thermal shock performance. Background technique [0002] In order to reduce oil dependence, air pollution, and carbon emissions, in recent years, new energy vehicles (NEVs) such as battery electric vehicles (BEVs) and plug-in hybrid The Internet is developing very rapidly, especially in China. For example, the cumulative sales of new energy vehicles in China in 2011 was only 8,159 units, while it increased to 1,728,447 units in 2017. [0003] As the new energy vehicle industry develops, high horsepower will require high power density from its electrical components such as batteries, motors and generators. Smaller, lighter and cheaper components will become m...
