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 the following components in parts by mass: 50 to 110 parts of a saturated polyester resin, 15 to 40 parts of a polyurethane resin, 5 to 20 parts of a curing agent, 30 to 200 parts of a flame retardant, 0.01 to 1 part of an antioxidant and 0.01 to 5 parts of a coupling agent. A small amount of polyurethane resin is added into the flame-retardant resin composition, and then carboxy groups can be introduced into the flame-retardant resin composition to increase functional groups capable of performing a crosslinking reaction with the curing agent in the flame-retardant resin composition and improve the crosslinking density of the flame-retardant resin composition, so that the heat resistance of the flame-retardant resin composition is improved. Moreover, the carboxy groups in the polyurethane resin and hydroxyl groups in the saturated polyester resin can both perform a crosslinking reaction with the curing agent, and an interpenetrating polymer network can be formed after curing, so that the compatibility of the polyurethane resin and the saturated polyester resin is improved. The invention also provides an adhesive and laminated busbar insulating adhesive film prepared from the flame-retardant resin composition, and a preparation method for the laminated busbar insulating adhesive film.

Description

technical field [0001] The invention relates to the field of laminated busbar insulating adhesive films, in particular to a flame-retardant resin composition and an adhesive prepared therefrom, a laminated busbar insulating adhesive film, 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-interfere...
