Abstract

The invention discloses a halogen-free resin composition. The halogen-free resin composition comprises the following components dispersing in an organic solvent, by weight: 5-10 parts of polyurethanemodified epoxy resin, 20-30 parts of multifunctional epoxy resin, 40-60 parts of a polyurethane and polyamide block copolymer, 10-20 parts of MQ resin, 5-10 parts of a curing agent, 0.2-0.5 part of acuring accelerator, and 15-20 parts of a phosphorus-containing flame retardant. The invention also discloses a flexible copper clad laminate prepared by using the halogen-free resin composition. The flexible copper clad laminate has excellent flexibility and folding resistance, low ion content, no dendritic crystallization during an ion migration test and good insulation property. Moreover, sincea toughening agent does not contain a saturated double bond, the flexible copper clad laminate has excellent aging resistance and can be applied in the field of high reliability requirements.

Description

technical field [0001] The invention relates to the field of polymer composite material manufacturing, in particular to a halogen-free resin composition and a flexible copper-clad laminate prepared therefrom. Background technique [0002] Flexible copper-clad laminate refers to a bendable sheet-like composite material made of insulating base film covered with copper foil. It is a large category of copper-clad laminates second only to rigid copper-clad laminates. In addition to the three major functions of insulation, mechanical support, flexible copper clad laminates can be bent, either statically or dynamically, which is very suitable for three-dimensional space installation. In recent years, the lightness, thinness and miniaturization of electronic products have directly promoted the rapid development of flexible copper clad laminates. [0003] At present, the common adhesives in adhesive flexible copper-clad laminates are mainly epoxy adhesives, and the epoxy adhesives u...
