Abstract

The invention discloses a low-density heat insulation pouring sealant for a new energy power battery module. The invention relates to the field of new energy automobile accessories. The low-density heat insulation pouring sealant comprises a component A and a component B, wherein the component A comprises the following components in percentage by weight: 30%-50% of vinyl silicone oil, 1%-3% of a platinum catalyst and 47%-69% of a modified heat-conducting filler, and the component B comprises the following components in percentage by weight: 30%-50% of vinyl silicone oil, 2%-4% of hydrogen-containing silicone oil, 1%-2% of a delay agent and 44%-67% of a modified heat-conducting filler. The low-density heat-insulation pouring sealant is prepared from the component A and the component B, theheat conductivity coefficient is about 0.1 W / (mK), after 10000 times of compression resilience tests, the compression resistance is kept at 90%, the density is only 0.55 g / cm < 3 >, the low-density heat insulation pouring sealant is very suitable for being used as a heat insulation material of a power battery pack, full-automatic potting can be achieved in the working process, manual assembly is not needed, and the assembly efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of new energy auto parts, more specifically, the invention relates to a low-density heat-insulating potting glue for new energy power battery modules. Background technique [0002] New energy vehicles are one of the important industries for the country to promote clean travel and smart cities, and the market for new energy vehicles is huge. The core component of new energy vehicles is the power battery. The battery pack obtained by connecting thousands of power batteries in series and in parallel has a high power density during operation. When working in summer, the outdoor ambient temperature is as high as 50°C. The heat from the air is conducted to the inside of the battery, which can easily cause thermal runaway of the battery. Therefore, it is extremely important to adopt a suitable heat insulation scheme to prevent the ambient heat from entering the battery. [0003] Insulation materials include heat i...
