Abstract

The invention relates to the technical field of material projects, in particular to a halogen-free flame-retardant resin composition. The halogen-free flame-retardant resin composition is used for a laminated busbar and is prepared from, by weight, 0-30 parts of saturated polyester resin A, 20-80 parts of saturated polyester resin B, 1-10 parts of curing agents, 10-100 parts of phosphorus containing fire retardant, 0-50 parts of nitrogenous fire retardant, 0-100 parts of filler, 0.01-1 part of antioxidant and 0.01-5 parts of coupling agents. All the components are mixed with an organic solvent, and a halogen-free flame-retardant adhesive with the solid content of 20%-60% by weight is obtained. The invention further relates to an insulation adhesive film for a laminated busbar and a preparation method of the insulation adhesive film for the laminated busbar, and the insulation adhesive film is prepared from the halogen-free flame-retardant adhesive. The insulation adhesive film for the laminated busbar is free of halogen, the flame retardant property can reach the UL94 VTM-0 stage, and excellent electrical insulation performance, high high-low-temperature peeling strength and excellent size stability, bending performance, damp-heat aging resistance, cold and hot impact performance and processing performance are achieved.

Description

technical field [0001] The invention relates to the technical field of material engineering, in particular to a halogen-free flame-retardant resin composition, a halogen-free flame-retardant adhesive containing the resin composition, and a laminated busbar made using the adhesive. Insulating adhesive film and its preparation method. Background technique [0002] Laminated busbars are also called composite busbars, laminated busbars, laminated busbars, composite copper bars, composite busbars, low-inductance busbars, etc. It is based on the electromagnetic field theory and makes the connection into a thin and wide flat section. It can make the parasitic inductance smaller, and has the advantages of low inductance, low impedance, anti-interference and compact size. Compared with traditional, bulky, time-consuming and troublesome discrete busbars and cable connections, the use of laminated busbars can provide a modern, easy-to-design, quick-installation and clear-structured po...
