Abstract

The present invention relates to resin composition and its application. Specifically, the present invention relates to a resin composition, which contains: 20 to 35 parts by weight of multifunctional epoxy resin; 8 to 15 parts by weight of isocyanate modified epoxy resin; 5 to 15 parts by weight of difunctional epoxy resin 10 parts by weight; 40-65 parts by weight of polyphenylene ether resin; and 8-16 parts by weight of cyanate resin. The present invention also relates to products of the resin composition, including resin films, adhesive sheets, prepregs, composite materials, laminates and printed circuit boards. Through the combination of different resins, this application realizes the superimposition of product performance, so that the product not only has a good appearance, but also has the comprehensive effects of heat resistance, low dielectric loss and easy processing.

Description

technical field [0001] The present invention relates to resin composition and its application. Background technique [0002] Polyphenylene ether resin has excellent dielectric properties due to its symmetrical molecular structure and low molecular dipole moment, and is favored by many workers engaged in new material development. The resin matrix with modified polyphenylene ether as curing agent has been widely used in composite substrates and high-frequency circuit boards. [0003] The resin composition of the prior art is: high molecular weight polybutadiene resin, containing more than 70wt% of vinyl, the weight average molecular weight MW is greater than 100000, accounting for 0-15wt% of composition weight; low molecular weight polybutadiene resin, containing More than 70wt% of vinyl groups have a weight-average molecular weight MW of 1000-10000, accounting for 10-40wt% of the weight of the composition; modified polyphenylene ether resins have a weight-average molecular w...
