Description
Technical Field
The utility model belongs to the technical field of fire-retardant product and specifically relates to a power module's fire-retardant glue is related to.
Background
The power module usually has circuit board, electric capacity, rectifier and diode etc. in power module's assembly process, usually need adopt the casting glue to carry out the embedment to whole power module, play waterproof, insulating and buffering effect. With the evolution of power module products, the conventional insulating pouring sealant is difficult to meet the requirements, and the pouring sealant is required to have flame retardant property and good heat conduction capability in the power modules of systems such as household appliances, batteries and the like. The traditional flame-retardant pouring sealant adopts aluminum hydroxide as a flame-retardant filler, and the price of the aluminum hydroxide is high, so that the flame-retardant sealant for the power module is provided.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an it is not enough to overcome above-mentioned condition, aims at providing the technical scheme that can solve above-mentioned problem.
The utility model provides a power module's fire-retardant glue, includes fire-retardant main part and protection main part, fire-retardant main part surface forming has the protection main part, the inside packing of protection main part has the protective layer, and the protective layer constitutes for vinyl blocking silicone oil, the inside first fire-retardant layer that is provided with of fire-retardant main part, first fire-retardant layer comprises ABS, the bottom surface of first fire-retardant layer is attached to the fire-retardant layer of second, and the fire-retardant layer of second comprises modified silica micropowder, the bottom surface of the fire-retardant layer of second is attached to the fire-retardant layer of third, and the fire-retardant layer of third comprises fire retardant modified silica micropowder, the bottom surface of the fire-retardant layer of third is attached to the fire-retardant layer of fourth, and the fire-retardant layer.
Preferably, the vinyl-terminated silicone oil consists of vinyl polydimethylsiloxane (Vi-PDMS) and vinyl-terminated polymethylvinylsiloxane (Vi-PMVS).
Preferably, the ABS organically unifies various performances of PS, SAN and BS.
Compared with the prior art, the beneficial effects of the utility model are that: the flame retardant is adopted to modify the silicon micropowder, so that the flame retardant property of the silicon micropowder is improved, the aluminum hydroxide is replaced, and the cost is reduced.
