Abstract
Description
technical field
[0001] The invention belongs to the field of electronic packaging materials, in particular to a phosphorus-containing polyester flame retardant epoxy resin composition. Background technique
[0002] Epoxy resin is one of the most widely used matrix resins in polymer matrix composites. It has excellent adhesion, chemical resistance, electrical insulation properties, mechanical properties, as well as easy processing, low shrinkage, and low coefficient of linear expansion. It has the advantages of low cost and low cost, and is widely used in the packaging of electronic components such as varistors, ceramic capacitors, diodes, and triodes. Since the limiting oxygen index (LOI) of epoxy resin is low, only 19.5, it is a flammable substance, so it needs to be flame-retardant. Usually, the method to improve the flame retardancy of epoxy resin is to introduce halogen-containing flame retardant into the epoxy resin, and mix it with flame retardant auxiliary such as an...
