It is an advantage of the invention that:Vinyl silicone oil is one of most basic composition of additional organosilicon casting glue, the present invention
Tensile strength and hardness, elongation at break are obtained by the vinyl silicone oil compounding for selecting different viscosities coefficient and contents of ethylene
With all higher organic silicon potting adhesive of elasticity, containing hydrogen silicone oil as cross-linking agent, when its active hydrogen content is higher, with organosilicon embedding
The crosslink density of glue will be larger, and stress can be made to be dispersed on more strands, higher tensile strength, hardness is shown
And elongation at break, but when active hydrogen content is too high, crosslinking rate is too fast, and strand has little time to form perfect cross-linked network
Network, and side reaction is also susceptible under the catalyst of Karst, make in organic silicon potting adhesive, to form more bubble, cause to lack
Fall into, so it is that 0.5Wt% is more suitable that the present invention selects active hydrogen content, the present invention selects vinyl polysiloxane to fill out as reinforcement
Material, be because with contents of ethylene is more, outer layer by organic team knowledge, molecular weight is little the characteristics of, and and organic silicon potting adhesive
There is good dispersion and the compatibility, preferable mobility and the transparency can be kept, and also can be occurred with containing hydrogen silicone oil
Hydrosilylation, it is possible to increase the mechanical property of casting glue, because the universal non-binding of organosilicon material, with base after solidification
There are space, the infiltration of long-time steam to cause fault occur between material, the present invention utilizes chemical reactive synthesis viscosifier, energy
The enough caking property for effectively improving organic silicon potting adhesive, tensile shear strength, do not affect viscosity and mobility, the present invention also to utilize
Filler improves the heat conductivity and anti-flammability of casting glue, but filler has pole with matrix in terms of molecular structure and physical property
Big difference, and the dispersibility of system is poorer, and the thermal conductivity of casting glue is lifted and is more difficult to, and the surface modification of filler can promote filler
Dispersion in the base, reduces the interface resistance on direction of heat flow, so as to can effectively lift the performances such as the thermal conductivity of system, receives
The characteristics of rice cell quartz powder has excellent waterproof, fire prevention, good fluidity, and there be a certain amount of hydroxyl silicon on surface itself
Alcohol, easily by coupling agent surface treatment, increases crosslinking, the effect of reinforcement, and the present invention is tied using silane coupler process, surface
Unification layer silane coupler, recycles photocrosslinking so as to form good crosslinking with acrylic resin, improves which resistance to old
Change, heat-resisting and mechanical strength, and there is in casting glue good dispersion and the compatibility, embedding adhesive curing prepared by the present invention
Hardness, resistance to compression, shock resistance are good afterwards, play insulation protection to various electronic devices and components, while rapid thixotroping after there is mixing
Performance, be particularly well-suited to the occasion that embedding device has micro gap, be worthy to be popularized.
