Abstract

The invention provides a halogen-free resin composition, comprising a large equivalent weight isocyanate modified epoxy resin, a large molecular weight dicyclopentadiene phenol epoxy resin, a curing agent, plasticized end epoxy acrylate rubber, a curing accelerator, and thermally conductive fillers. The invention also provides RCC, laminated board, adhesive film and metal foil-clad laminated board prepared by using it. The halogen-free resin composition has excellent toughness, and the thermal conductivity of the aluminum-based copper-clad laminate made of it can reach more than 2.2W / m.k. The peel strength of the folded surface (T288°C, 10s)≥1.8N / mm, the thermal stress of the bent surface is 288°C dip soldering≥60min, after bending 360° spirally, the breakdown voltage of the bent surface after heat treatment is ≥7kV, at Cycle treatment 1000 times under certain conditions, breakdown voltage ≥ 6kV.

Description

technical field [0001] The invention belongs to the technical field of metal foil-clad laminates, and in particular relates to a halogen-free resin composition, RCC, adhesive film and metal foil-clad laminates. Background technique [0002] LED is more and more applied to landscape lighting, architectural lighting, indoor lighting, and stage lighting due to its advantages of environmental protection, low energy consumption, and long life. Conventional LED substrates are planar. With the development of the lighting industry, LED lighting tends to develop in a 3D direction. [0003] Compared with conventional LED lighting, 3D-LED lighting requires the base aluminum substrate to have excellent toughness and flexibility under the conditions of ensuring excellent heat dissipation, heat resistance, insulation, and peel strength, so as to meet the needs of the board during PCB processing and bending. There is no breakage or delamination of the insulation layer. [0004] In order ...
