A kind of resin composition and its application

Abstract

The invention discloses a resin composition. The resin composition is prepared from the following components in parts by weight: 10-30 parts of epoxy soybean oil modified epoxy resin, 70-90 parts of phosphorus modified phenolic epoxy resin, 15-20 parts of biphenyl type phenolic resin, 5-20 parts of nonyl phenol modified benzoxazine, 70-103 parts of silicon dioxide, 20-50 parts of boehmite, 0.08-0.85 part of diphenyl imidazole, 30-80 parts of acetone and 30-80 parts of ethylene glycol monomethyl ether. The resin composition is used for preparing a copper-clad plate. According to the resin composition, the problems that a copper-clad plate is poor in dimensional stability and heat resistance after being solidified by an existing adhesive resin system are solved; the heat resistance and dimensional stability of CEM-3 are improved; and the coefficient of thermal expansion of the plate is also improved, so that the production technology of the CEM-3 reaches the advanced level at home.

Description

technical field

[0001] The invention belongs to the technical field of copper-clad laminates, in particular to a resin composition, and also relates to a copper-clad laminate made of the resin composition. Background technique

[0002] With the rapid development of electronic integration technology and assembly technology, printed circuit board (Printed circuitboard, PCB) manufacturers also have higher requirements for the dimensional stability and thermal expansion coefficient (Coefficient of Thermal Expansion, CTE) of CCL. Copper Clad Laminate (CCL) prepared by epoxy resin-based composite materials with phenolic resin as curing agent has good heat resistance, medium resistance, CAF (ion migration) resistance, etc., but there are some problems after curing. There are problems such as poor dimensional stability and high brittleness of the plate. However, although the epoxy resin-based composite material cured with dicyandiamide has good dimensional stability, it has poor he...
