Problems solved by technology

[0004] At present, the conventional high-frequency resin composition is mostly made of cyanate ester, polyphenylene ether and other materials to prepare high-frequency copper-clad laminates, and the cost is relatively high.
However, the application of benzoxazine resin to the resin composition will affect the stability of the resin composition due to the halogen in the flame retardant, which will greatly reduce the heat resistance of the copper clad laminate, and cannot achieve the lead-free process in the PCB manufacturing process. requirements

Abstract

The invention relates to a halogen resin composition and an application thereof. The halogen resin composition is prepared from the following raw materials in parts by weight: 20-50 parts of dicyclopentadiene epoxy resin, 10-40 parts of styrene-maleic anhydride copolymer, 10-30 parts of benzoxazine resin, 20-40 parts of halogenous fire retardant, and 5-20 parts of multi-functional group epoxy resin, wherein the halogenous fire retardant is at least one of the decabrominated dipheny ethane, tri(tribromophenyl) triazine, brominated polyolefin, brominated polystyrene, ethyl-di(tetrabromobenzene o-dicarboximide), decabromodiphenyl ether, hexabromocyclododecane, eight bromo ether, tetrachlorophthalic anhydride, Hexachlorocyclopentadiene and perchlorinated cyclopentyl decane. A metal foil substrate made of the halogen resin composition has the advantages of low dielectric constant and dielectric loss, excellent heat resistance, good machinability and low swelling coefficient and can be well applied to a composite board.

Description

technical field [0001] The invention relates to a resin composition, in particular to a halogen-containing resin composition and its application. Background technique [0002] At present, the electronics industry is developing rapidly, and the requirements for the performance of copper clad laminates are getting higher and higher, especially in the three major portable electronic products, satellite transmission and communication electronic products. The factors that can directly affect the performance of the above products are basically attributed to the dielectric coefficient (Dk) and dielectric loss tangent (Df) of the substrate. The smaller the dielectric coefficient of the substrate, the faster the signal transmission speed and the dielectric loss. The smaller the tangent value, the more complete the transmission of the signal, and the higher the authenticity of the signal. Especially the current electronic products are small, light and thin, and the transmission frequ...
