Abstract

The invention relates to an insulating protective glue, a preparation method and application thereof, and belongs to the technical field of chemical materials. The insulating protective adhesive is mainly prepared from the following raw materials in parts by weight: 40-55 parts of oligomers, 45-60 parts of active monomers, 3-8 parts of photoinitiators, and 0-10 parts of additives , the oligomer is polybutadiene acrylate; the active monomer is at least one of monofunctional acrylate and difunctional acrylate. The insulating protective adhesive can be applied by screen printing or spraying, and it can be quickly cured by UV light, without lamination, and not limited by shape and size; it can withstand electrolyte and various acids and alkalis for a long time, and prevent leakage; insulation Good, can withstand voltage above 1000V, prevent leakage; good adhesion and wear resistance, long-term use will not cause colloid shedding or severe wear. It can be used for insulation and isolation protection on the surface of the aluminum casing of the power battery, and can also be used in other similar applications, and has the advantage of a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to an insulating protective glue and a preparation method and application thereof. Background technique [0002] With the increasing energy crisis and environmental pollution, the development of high-efficiency, energy-saving, zero-emission clean pure electric vehicles has become an inevitable trend in the development of the domestic and foreign automobile industries. In recent years, with the development of technology and the vigorous promotion of the system, China has become the commanding height of the development of electric vehicles in the world. In 2016, the total sales of buses (excluding tourist buses) in China was about 100,000 units, of which about 70,000 were pure electric buses and 17,000 were plug-in hybrid buses, accounting for 87% of the total sales. At the same time, foreign countries are also ushering in a boom in development. Norway and the Netherlands ...
