Description
Technical field
The present invention relates to a kind of liquid infiltration encapsulating material with exceptional overcoat pressure resistance, it be it is a kind of with alkyd resin, it is poly-
Based on the three kinds of resin collocation uses of urethane resin and organic siliconresin, using silica flour or aluminium oxide as main stuffing, and it is dissolved in
Liquid-type impregnation enveloping material in solvent, coating can reach 2500VAC under 0.4mm thickness after solidification, and 1min does not puncture.
Background technology
In Electronic Packaging field, mainly uses epoxy resin, phenolic resin and organic siliconresin as matrix resin, match
Curing agent, filler, auxiliary agent are closed to have the function that insulation, heat-resisting, isolation vapor, for varistor, to coating
It is required that it is also higher and higher, in addition to requiring coating that there is the pressure resistance of higher coating, while also requiring coating that there is high temperature resistant, cold-hot
Impact and high temperature resistant direct current ageing properties.
The system of currently used epoxy resin and phenolic resin can accomplish reach under 0.4mm thickness
2500VAC, 1min do not puncture, but the resin system heat-resisting quantity is poor, cannot meet the requirement being used for a long time at high temperature,
And cold-resistant thermal impact and high temperature resistant direct current ageing properties are poor.
Silicone resin system heat-resisting quantity is good, while having excellent cold-resistant thermal impact and high temperature resistant direct current aging
Can, but coating pressure resistance is poor, in order to reach 2500VAC, 1min does not puncture, and silicone resin system needs to increase coating layer thickness
It is added to about 1.0mm, this aspect can use more coating to cause cost to improve, on the other hand also be unsatisfactory for electronic component
The requirement increasingly minimized is not used to have thickness in the product strictly limited.
Currently, single resin system can not meet these requirements simultaneously substantially, the present inventor by largely studying,
It was found that by the collocation of different resins, may be implemented to meet these requirements simultaneously.
Invention content
In view of the deficiencies of the prior art, the invention discloses a kind of liquid infiltration encapsulating material with exceptional overcoat pressure resistance,
Solve the problems, such as the existing resistance to pressure difference of encapsulating material coating, meanwhile, the coating after solidification also has high temperature resistant, cold-resistant thermal shock and Nai Gao
The excellent properties such as warm direct current aging.
Technical scheme is as follows：
