Abstract

The invention provides a halogen-free resin composition. The halogen-free resin composition comprises the following components in parts by mass: 40-110 parts of saturated polyester resin, 5-40 parts of phenolic resin, 1-20 parts of a curing agent, 10-150 parts of a halogen-free flame retardant, 0-100 parts of a filler, 0.01-1 part of an antioxidant and 0.01-5 parts of a coupling agent. In the halogen-free resin composition, the phenolic resin has good flame retardance and excellent heat resistance, and both the saturated polyester resin and the phenolic resin contain hydroxyl groups and can react with the curing agent to form an interpenetrating polymer network, so that the obtained cured product system has excellent high-temperature adhesion and flame retardance. The invention further provides an adhesive and a laminated busbar insulating adhesive film prepared from the halogen-free resin composition, and a preparation method of the laminated busbar insulating adhesive film.

Description

technical field [0001] The invention relates to the field of insulating adhesive films for laminated busbars, in particular to a halogen-free 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 anti-i...
