Problems solved by technology

Adding a curing agent makes the saturated polyester resin form a partially cross-linked network structure, which can certainly improve the high-temperature bonding performance of the saturated polyester adhesive, but the saturated polyester adhesive forms a partially cross-linked network structure before pressing, although the overall retention Thermoplastic, but it has formed a certain three-dimensional network structure, has no obvious melting point, and the fluidity and wettability at high temperatures are also greatly redu

Abstract

The invention provides a thermoplastic resin composition. The thermoplastic resin composition comprises the following components in parts by mass: 50-85 parts of thermoplastic polyurethane resin, 5-20 parts of saturated polyester resin, 0.5-8 parts of a compatilizer, 0.1-1 part of an antioxidant and 20-100 parts of a flame retardant, wherein the thermoplastic polyurethane resin has excellent flexibility and high and low temperature resistance; and the saturated polyester resin has low melting point, poor high temperature resistance, good aging property and excellent adhesive property with metal and an insulation film. The thermoplastic polyurethane resin and the saturated polyester resin are blended and modified, a small amount of the compatilizer is added, polymer alloy with excellent compatibility can be obtained, and the polymer alloy has good high and low temperature impact property, aging property and adhesive property. The resin composition does not contain a curing agent, has good high temperature liquidity and can meet low temperature lamination requirements. The invention also provides an adhesive made by adopting the thermoplastic resin composition, an insulation adhesive film used for a laminated bus bar 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 thermoplastic 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, laminated busbars, composite copper bars, composite busbars, etc., and the English name is Laminated Busbar. It is mainly based on the electromagnetic theory, and the wide and thin copper bar is hot-pressed with a very thin insulating material. The opposite current passes through the adjacent wires, and the magnetic fields cancel each other, which can reduce the parasitic inductance. As the bonding between the conductors in the laminated busbar and the insulating film of the insulating material, its performance has a crucial impact on the safety and reliability of the laminated busbar. The ins...
