Problems solved by technology

But in fact, phosphorus-based flame retardants are still not considered the most ideal environmental protection materials, because phosphorus-based flame retardants will cause oxidation of lakes and rivers due to hydrolysis, which will lead to another environmental issue; on the other hand, phosphorus-based flame retardants Due to its high water absorption and thus dissociation characteristics, the reliability of electronic products will decrease or fail, and it may produce toxic gases (such as methylphosphine) during combustion
Therefore, phosphorus-based flame retardants are likely to be completely banned in the future

Abstract

The invention provides a halogen-free non-phosphorization flame-retardant epoxy resin composition and a preparation method thereof. The preparation method comprises the following steps of: premixing the common epoxy resin, flame-retardant epoxy resin, a curing agent, a curing accelerator, a flame-retardant synergistic agent and an inorganic filler; melting, mixing and extruding; and crushing and sieving to prepare the halogen-free non-phosphorization flame-retardant epoxy resin composition. The flame-retardant epoxy resin composition does not contain harmful substances such as halogen, diantimony trioxide, phosphorus and the like, has excellent fire resistance which can reach UL94V-O grade flame-retardant standard and high electrical property, can be applied in the fields of electronic packaging and copper-clad laminate.

Description

Technical field [0001] The invention belongs to the field of polymer materials, and relates to an epoxy resin composition, in particular to a non-halogen, non-phosphate flame-retardant epoxy resin composition and a preparation method thereof. Background technique [0002] Epoxy resin is a product prepared by the condensation reaction of a compound with an epoxy group and a polyhydric hydroxyl or polyol compound. It is one of the most widely used matrix resins in polymer matrix composites. It has high strength and excellent adhesion. Junction, chemical resistance, electrical insulation properties, mechanical properties, as well as easy processing, low shrinkage, low linear expansion coefficient and low cost, are widely used in electronic components such as varistors, ceramic capacitors, diodes, and triodes Package. [0003] However, since the limiting oxygen index (LOI) of epoxy resin is low, only 19.5, it is a flammable substance, so it needs to be flame-retardant. Generally, the...
