Problems solved by technology

Boron-based flame retardants are also divided into two categories: additive type and reactive type. Zinc borate is a representative of additive type flame retardants and is widely used, but it also has the defects of additive type flame retardants.

Embodiment 1

[0039] A preparation method of an epoxy resin composition with excellent flame retardancy and flame-retardant durability is as follows:

[0040] Premix epoxy resin, self-made N-B synergistic high flame retardant curing agent (A), other curing agents, curing accelerators and inorganic fillers according to the ratio of parts by mass. The premixing time is 3 to 10 minutes, and the speed is 600 ~1200r / min; melt extrusion mixing, extruder temperature 80~160°C, extruder speed 800~2400r / min, tablet cooling and crushing, crushing and sieving through ACM mill to obtain the epoxy resin combination.

[0041] Wherein, the synthetic method of N-B synergistic high flame retardant curing agent (A):

[0042] (1) After finishing the four-neck flask, stirrer, distillation column, condenser tube and temperature-controlled heating mantle, add 120g of neopentyl glycol and 168.21g of 1,3-dimethylol-5,5-dimethylhydantoin, and raise the temperature To 110~130℃, stirring and melting;

Abstract

The invention relates to an epoxy resin composition with the excellent flame resistance and flame resistant durability and a preparation method thereof. The epoxy resin composition is powdery, and prepared from the components, in parts by mass: 24-40 parts of epoxy resin, 10-26 parts of self-made N-B synergistic high flame resistance curing agent, 0-6 parts of other curing agent, 0.02-0.6 part ofcuring accelerator, 15-30 parts of flame resistant synergist and 20-35 parts of organic filler. The epoxy resin composition adopts nitrogen and boron to resist flame synergistically, the flame resistant elements are all located on the molecular chain, thus flame resistance, free of halogen and free of phosphate of an electronic packaging material are achieved, and the electronic packaging materialis endowed with the outstanding flame resistant durability. The epoxy resin composition has the multi-branched structure, and the machinability, the using manufacturability, the physical and chemicalproperty, the electrical property and the reliability of the electronic packaging material can be effectively considered.

Description

technical field [0001] The invention belongs to the field of electronic packaging materials, in particular to an epoxy resin composition which can be used in electronic packaging materials and has excellent flame retardancy and durability and a synthesis method thereof. Background technique [0002] Epoxy resin refers to a polymer containing two or more epoxy groups, with aliphatic, alicyclic or aromatic organic compounds as the backbone and formed by the reaction of epoxy groups; epoxy groups can be located in the molecular chain The end, middle or ring structure of the segment; it is one of the most widely used matrix resins in polymer matrix composites. Due to the special molecular structure of epoxy resin, epoxy resin has excellent adhesion, heat resistance, chemical resistance and excellent electrical insulation properties, and is easy to process, low shrinkage, small linear expansion coefficient and low cost. Advantages such as low cost. Widely used in the packaging ...
