Abstract

The invention discloses a filling foaming potting silicon rubber for a new energy power battery. The silicon rubber is prepared from the following raw materials in percent by mass: 25%-35% of vinyl silicone oil; 5%-15% of alpha,omega-dihydroxylpolydimethylsiloxane; 12.5%-15% of a crosslinking agent; 5%-7.5% of aluminum hydroxide; 20%-30% of a flame-retardant powder; 10%-15% of antimony hydroxide;0.5%-0.7% of a treatment agent; 0.1%-0.18% of a delay agent; 0.2%-0.6% of a catalyst; 0.1%-0.18% of ethynyl cyclohexanol; and 0.1%-0.15% of a dyeing filler. The above-mentioned material is subjected to rubber potting into a paper battery pack, and thereby the entire space in the battery pack can be well filled. At the same time, the obtained filling foaming potting silicon rubber for a new energypower battery has excellent performance.

Description

technical field [0001] The invention relates to the technical field of new energy power batteries, in particular to a filling foaming potting silica gel for new energy power batteries, a preparation method and an application thereof. Background technique [0002] Power battery new energy vehicles are based on the principle of converting electrical energy provided by batteries into mechanical energy to achieve clean and environmentally friendly transportation. Therefore, there are high requirements for hard indicators such as battery storage, fast charging and discharging, and energy density. At the same time, the safety and stability of batteries performance, long life and other necessary requirements for use. [0003] In practice, the electrodes of the battery are easy to be damp and short-circuited, the electrodes are easy to loosen and disconnect during the bumping process of the car, and the discharge current is very large. These factors are likely to cause thermal runaw...
