Problems solved by technology

However, this modified saturated polyester adhesive can only be used for laminated busbars with an operating temperature of 105°C. As the temperature rises, the high-temperature bonding strength of the saturated polyester adhesive decreases rapidly, which cannot meet the requirements for higher operating temperature lamination. Application requirements for busbars

Abstract

The invention provides a flame-retardant resin composition, which comprises, by mass part, 40-110 parts of a saturated polyester resin, 5-40 parts of a phenolic resin, 1-20 parts of a curing agent, 10-100 parts of a fire retardant, 0.01-1 part of an anti-oxidant and 0.01-5 parts of a coupling agent. A small amount of phenolic resin is added in the flame-retardant resin composition, so that aromatic rings are introduced to the flame-retardant resin composition and thermal resistance and flame resistance of the flame-retardant resin composition are improved. Both of the phenolic resin and the saturated polyester resin contain hydroxyl groups, which react with the curing agent for a cross-linking curing reaction, so that interpenetrating polymer networks are formed and a condensate excellent in thermal resistance, flame retardance and high-temperature bonding performance is obtained. The invention further provides an adhesive prepared from the flame-retardant resin composition, an insulation adhesive film used for a laminated busbar, and a preparation method of the insulation adhesive film.

Description

technical field [0001] The invention relates to the field of insulating adhesive films for laminated busbars, in particular to a flame-retardant resin composition and an adhesive prepared therefrom, an insulating adhesive film for laminated busbars, and a method for preparing the insulating adhesive film. Background technique [0002] Laminated busbars are also called composite busbars, composite busbars, laminated busbars, composite copper bars, low-inductance busbars, etc., and their English name is called Laminatd Busbar. As a connection bar with a multi-level composite structure, the laminated busbar can be regarded as the expressway of the power distribution system. Compared with the traditional complex, bulky, time-consuming and labor-intensive wiring methods, laminated busbars can provide a high-tech and easy-to-design power distribution system with a clear structure. It has the characteristics of repeatable electrical performance, low inductive impedance, strong ant...
