Problems solved by technology

Commonly used synergists are mainly some inorganic metal salts such as ammonium tripolyphosphate, molybdenum oxide, magnesium hydroxide, etc. The addition of these synergists is relatively high, which not only makes the system processing difficult, but also affects the quality of the product. Other properties are adversely affected, such as reducing the mechanical properties of the product, etc.

Abstract

A smoke-suppressing benzoxazine resin composition and a preparation method thereof. The invention discloses a benzoxazine resin composition with good smoke-suppressing effect, and its components include: (A) benzoxazine resin; (B) epoxy resin; (C) smoke suppressant; (D) Curing agents and accelerators, and other fillers and / or additives. The present invention includes specific smoke suppressant components to make the produced substrate achieve the effect of suppressing smoke, and further achieve the purpose of producing copper foil substrates and printed circuit boards with low smoke production.

Description

technical field [0001] The invention relates to a polymer composition, in particular to a benzoxazine resin composition with excellent smoke suppression effect applied to copper foil substrates and printed circuit boards. Background technique [0002] At present, in the technical field of printed circuit boards, researches on two different systems, bromine flame retardant and halogen-free flame retardant, exist at the same time, so as to make corresponding choices according to the different needs of the terminal. However, halogen-free is currently a trend in the global electronics industry. Countries around the world and related electronics manufacturers have successively formulated mass production schedules for halogen-free electronic products for their electronic products. Environmentally friendly halogen-free electronic products are always the general trend, and the demand for halogen-free products suitable for low, medium and high fields is increasing. Therefore, the hal...
