Abstract

The invention discloses an epoxy electronic pouring sealant and a preparation method thereof. The epoxy electronic pouring sealant is prepared from E-51 biphenyl A epoxy resin, an epoxy diluent, an epoxy toughening agent, a curing agent, packing and additives in a mixed manner. According to the epoxy electronic pouring sealant disclosed by the invention, the biphenyl A epoxy resin is taken as main body resin, the types and the additive amounts of the accelerant and the packing are screened, and thus optimal formulae can be selected. The prepared epoxy electronic pouring sealant is good in heat conduction property, good in flame retardancy, small in internal product stress and applicable to pouring sealing of large-power electronic elements, and various properties of the epoxy electronic pouring sealant are superior to those of similar pouring sealants in China and other countries.

Description

A kind of epoxy electron pouring sealant and preparation method thereof
Technical field
The present invention relates to casting glue field, be specifically related to a kind of epoxy electron pouring sealant.
Background technology
The globality of casting glue energy strengthening electronic device prepared by epoxy resin, improves external shock, the opposing of vibrations Power, keeps the insulating properties of electronic device, the beneficially miniaturization of electronic device, lightweight, it is to avoid electronic component and circuit Directly exposing, can greatly improve the waterproof and moistureproof performance of electronic device, the service life and the reduction that extend electronic device make Use cost.But, along with the development of electric industry, the requirement to epoxy fill-sealing materials is more and more higher.Pure epoxy tree The solidfied material elastic modelling quantity that fat casting glue is formed is poor, and fragility is big, easy to crack, it is difficult to meet the use requirement of some occasion.For Ensure the reliability of embedding device, good heat-sinking capability and the electrical insulation properties of excellence, it is necessary to epoxy pouring sealant Formula is adjusted and optimizes, and to improve fire-retardant, the heat conductivity of casting glue, reduces internal stress.
Summary of the invention
Present invention aim at, it is provided that a kind of excellent heat conductivity and also there is flame retardant epoxy electron pouring sealant.
It is another object of the present invention to provide the preparation method of a kind of epoxy electron pouring sealant.
The technical solution adopted in the present invention is:
A kind of epoxy electron pouring sealant, it is characterised in that be mixed with according to percentage by weight by following components and form:
E-51 bisphenol A epoxide resin 15-25 part
Epoxide diluent 3-7 part
Epoxy toughening agent 3-7 part
Firming agent 1-4 part
Filler 50-75 part
Auxiliary agent 3-8 part.
Further, described filler includes silicon powder, aluminium oxide, ground calcium carbonate.
Further, described auxiliary agent includes defoamer, wetting agent, epoxy accelerator.
The method wherein preparing above-mentioned epoxy electron pouring sealant, its step is as follows:
(1) being proportionally added into epoxy resin, epoxide diluent, epoxy toughening agent, epoxy accelerator, defoamer is to high speed dispersor In, dispersion machine speed is 1000r/min, is uniformly dispersed, and then dispersion limit in limit adds partial filler, continues to be uniformly dispersed, finally Vacuum defoamation, prepares component A;
(2) in proportion firming agent, wetting agent joins in high speed dispersor, mix homogeneously, is subsequently adding remaining filler, continues Continue and be uniformly dispersed, last vacuum defoamation, prepare B component;
(3) respectively A, B component are heated to 30 DEG C, weigh A, B component for 1:1 in mass ratio and be uniformly mixed, then existing Deaeration 10min in vacuum drying oven, injects in encapsulating die, solidifies 3h, i.e. obtain epoxy electron pouring sealant at 120 DEG C.
The present invention provides the benefit that relative to prior art: the epoxy electron pouring sealant of the present invention, uses bisphenol A-type ring Accelerator, filling kind and addition, as matrix resin, are screened, select optimization formula by epoxy resins.The epoxy prepared Casting glue heat conductivity is good, and has anti-flammability, and product internal stress is little, and properties is superior to external similar casting glue, is suitable for Embedding in great-power electronic element uses.
