Problems solved by technology

[0005] The above existing patents have proposed that the use of active ester curing agent to cure epoxy resin can reduce the dielectric constant, dielectric loss factor and water absorption rate of the cured product. The disadvantage is that it is difficult to further reduce the dielectric constant while maintaining the adhesive force. constant, dielectric loss value and water absorption and increase storage modulus and flexural strength

Abstract

Disclosed is a halogen-free resin composition. The halogen-free resin composition comprises: (A) 10-60 parts by weight of dicyclopentadiene benzoxazine resin; (B) an epoxy resin; (C) an active ester curing agent; and (D) a phosphorus-containing flame retardant, based on 100 parts by weight of the total amount of organic solids of (A), (B), (C) and (D). A prepreg and a laminate that are manufactured from the halogen-free resin composition have low dielectric constant, low dielectric loss, low water absorption rate, high dimensional stability, and excellent heat resistance, fire resistance, processability and chemical resistance.

Description

technical field [0001] The present invention relates to a halogen-free resin composition and a prepreg and a laminate using the same, which have low dielectric constant, low dielectric loss factor, low water absorption, high dimensional stability, high heat resistance and good Flame retardancy, processability, chemical resistance. Background technique [0002] Traditional printed circuit laminates usually use brominated flame retardants to achieve flame retardancy, especially tetrabromobisphenol A epoxy resin, this brominated epoxy resin has good flame retardancy, but it is in Combustion produces hydrogen bromide gas. In addition, in recent years, carcinogens such as dioxin and dibenzofuran have been detected in the combustion products of electronic and electrical equipment wastes containing halogens such as bromine and chlorine, so the application of brominated epoxy resins is limited. On July 1, 2006, the EU's two environmental protection directives "Directive on Waste E...
