Abstract

The present invention relates to the technical field of UV-curable coatings, in particular to a UV-curable leakage protection coating, a preparation method and its application, comprising the following components in parts by weight: 10-20 parts of epoxy acrylate, polyurethane acrylate 5‑15 parts, 20‑30 parts of monofunctional acrylate, 15‑25 parts of difunctional acrylate, 5‑15 parts of multifunctional acrylate, 5‑15 parts of pigment and filler, 3‑8 parts of photoinitiator, silane coupling 1-5 parts of additive and 0.5-3 parts of auxiliary agent can be applied to the surface of aluminum and other metal surfaces on the battery cell in the battery pack to form an insulating protective coating. The present invention solves the problem that in the prior art, the surface of the aluminum shell of the lithium battery is coated with a blue film, the bonding is not firm, hollowing is easy to occur when the temperature changes, and the insulation of the battery pack is affected.

Description

technical field [0001] The invention relates to the technical field of ultraviolet light-curing coatings, in particular to an ultraviolet light-curing leakage circuit breaker protection coating, a preparation method and applications thereof. Background technique [0002] New energy vehicles have the advantages of energy saving, emission reduction and environmental protection. They are of great significance to ensure national energy security, solve environmental pollution, and achieve sustainable social and economic development. It is an inevitable trend to achieve sustainable development. As the core components of new energy vehicles, power batteries are an important focus for the development of the new energy vehicle industry. The composition of the power battery of different models may be different, but on the whole it is a process from a single cell to a module, and a module to a battery pack. The lightweight of battery packs has become a market trend. Therefore, the use...
