Advantageous effect：Object is carried out to inorganic matter by lauryl amine polyoxyethylene ether, silane coupling agent, P-hydroxybenzoic acid etc.
Reason, chemical surface treatment, other than improving dispersibility and compatibility of the inorganic material in organic system, whisker is being surface-treated
Surface is etched and organic modification in the process, by its with organic matrix it is compound after, over time, organic matrix and fibre
Molecule, the atom of dimension shape inorganic body two-phase interface are easier to interpenetrate, invade, spread, migrating, inorganic body and organic matrix two
Boundary gradually forms an interface phase all different from inorganic body and organic matrix, over time interface mutually constantly
Sprawling extension, the function of inorganic body are extended in company with sprawling, whisker can it is gradually thicker (like reinforcing bar is for a long time in concrete, by
Also can be thicker in the gradual infiltration reinforcing bar of concrete, i.e., reinforcing bar periphery generates interface phase), interface is mutually due to inorganic material-modified dose
With fully merging for organic matrix so that it has the advantages that anti-aging, long lifespan；The present invention has carried out ruler to each inorganic material
Very little optimization, wherein the calcium carbonate crystal whisker of micron level is threadiness, and adhesive (plugging material) surface after hardening forms one
Protection network to be opened, the skeleton of barrier layer is formed, whisker has acid and alkali-resistance, high temperature, high-strength, high tenacity characteristic, the skeleton formed,
It has excellent performance, not only self stability is good, and can improve the adhesive toughness after solidification, and nanoscale barium sulfate and silica are filled out
It fills in being formed by the interface phase separation that within the grid of protection network and its they are generated, further promotes the barrier of barrier layer
Ageing resistance, nanoscale barium sulfate and silica are limited by grid, it is ensured that its stability, can effectively prevent moisture,
The infiltration of light etc.；Pass through polydibromstyrol, different phenylpropyl phenyl phosphate ester, antimony oxide, triaryl phosphate so that glue
There is good flame retarding function after glutinous agent (plugging material) solidification, improve safety；Adhesive (plugging material) after solidification
Compact structure, air-tightness are good.
Specific implementation mode
Below in conjunction with specific implementation mode in specification, the invention will be further described, but the invention is not limited in
Following embodiment.
The material prepared using the present invention is sealed cable and installs the process of interporal lacuna：
First, cable is passed through and is reserved in the mounting hole of switchgear bottom, by actual installation circuit drawing by cable
It is connected and fixed with switchgear inner copper line or other connecting pins, after completing cable installation, cable stabilization is fixed, along cable
Line is toppled over mounting hole gap edge in liquid fire retardant insulating plugging material, when liquid fire retardant insulating plugging material handle
Cable is good with mounting hole gap filling, and cooperation is using ultraviolet light 6-15min until plugging material foamable gel is molded, so
The insulation sleeve sliding sleeve being set in advance on cable, which is set to, afterwards can block the position of cable and mounting hole gap.
