Abstract

The invention relates to an adhesive for a halogen-free high-Tg and low-dielectric type copper-clad plate, and a preparation method thereof. The adhesive is prepared from, by weight, 2-80 parts of a phosphonitrile flame retardant, 5-80 parts of isocyanate modified epoxy resin, 20-70 parts of modified polymeric anhydride, 5-50 of an active ester curing agent, 5-80 parts of biphenylphenol modified epoxy resin, 0.005-1.0 part of a metal type catalyst, 0.005-1.0 part of an imidazole catalyst, 10-60 parts of an inorganic filler, 0.1-5.0 parts of silane, 1-10 parts of a toughener and 10-60 parts ofan organic solvent. The epoxy glass cloth-based copper-clad plate produced by using the adhesive prepared in the invention has a Tg value of 180 DEG C or above and a Z-axis CTE of 3.0%, or less has aTD of 360 DEG C or above and a T288 of 60 min or above in the heat resistance field, and has a copper foil peel strength (1 OZ) of 1.2 N/mm or above.

Description

technical field [0001] The invention relates to an adhesive, in particular to an adhesive for a halogen-free high Tg low dielectric copper clad board and a preparation method thereof. Background technique [0002] The 21st century has entered a highly informationized society. Computers, mobile communications, and networks have gradually penetrated into every corner of society and people's lives. Human life is steadily developing in the direction of high informationization. Information processing and information communication constitute Two technical pillars in the development of highly informationized science and technology. In order to meet the ultra-large-capacity information transmission brought about by the rapid development of information technology, as well as the rigid requirements of ultra-fast and ultra-high-density information processing, higher requirements are put forward for printed circuit boards and copper-clad laminates. The specific requirements of its produ...
