Problems solved by technology

Although the copper-clad laminate composition uses cyanate resin and styrene maleic anhydride and its derivatives to improve the glass transition temperature of the epoxy resin system and has excellent high-frequency dielectric properties, but the system used There are acid anhydride groups in the molecular structure of the styrene-maleic anhydride copolymer, which can generate carboxyl groups with poor thermal stability and heat and humidity resistance; Used together, it will further deteriorate the heat and humidity resistance
Although the resistance to heat and humidity has been improved to a certain extent by adding epoxy resin, the improvement is limited and cannot be fundamentally eliminated. In this way, during the PCB manufacturing process, the board is easily corroded by moisture and delaminated and exploded, and the product is qualified. very low rate

Abstract

The invention discloses a thermosetting resin composition which comprises epoxy resins except brominated epoxy resin, an styrene maleic anhydride copolymer and an additive flame retardant, and further comprises an active ester. The thermosetting resin composition can be used for preparing resin sheet materials, resin compound metal copper foils, prepregs, laminates, copper clad laminates, printed circuit boards, etc. The thermosetting resin composition substantially reduces probability of delamination of PCB substrate, overcomes disadvantages of deterioration of system dielectric properties due to introduction of tetrabromobisphenol A, and has advantages of good heat stability and heat and humidity resistance, low dielectric constant and dielectric loss tangent, and good flame resistance.

Description

technical field [0001] The present invention relates to a kind of resin composition, specifically, the present invention relates to a kind of thermosetting resin composition and its application in resin sheet, resin composite metal foil, prepreg, laminated board, metal foil clad laminated board and printed circuit board in the application. Background technique [0002] In recent years, with the development of high-performance, high-functionality and networking of computers and information communication equipment, in order to transmit and process large-capacity information at high speed, the operating signal tends to be high-frequency, so the circuit substrate is moving towards high-layer, high- The development of wiring density puts forward new requirements for the substrate materials used. These requirements include: 1. Good dielectric properties (that is, low dielectric constant and low dielectric loss factor), and can be used in a wide range of It remains stable under te...
