3-5。
Further, the castor oil modified carbide slag preparation method is：Castor oil is heated to 250 DEG C, insulation
40min, it is stand-by, use mass fraction to be soaked 2 hours at 40 DEG C for 10% acid solution carbide slag, then filtered, dried
Do to constant weight, carbide slag and castor oil are then pressed 50 again:1 mass ratio uniformly mixes, and is ground 2 hours, then adds again
Heat is incubated 30min, naturally cools to room temperature, produce to 500 DEG C.
Further, the carbide slag granularity is 950 mesh.
Further, the acid solution is the salpeter solution that mass fraction is 6.5%.
Further, the drying temperature is 120 DEG C.
Further, the inorganic nanometer powder is nano-bentonite powder, granularity 85nm.
Further, the porosity of the diatom ooze is 90%, and specific surface area is 55 ㎡/g.
The present invention has advantages below compared with prior art：Instrument plastic casing prepared by the present invention, by largely trying
Research is tested, rational compatibility is carried out to material composition, it is double hard using polypropylene, castor oil modified carbide slag, diatom ooze, vinyl
The synergy of acyl amine so that manufactured instrument plastic casing has high refractive index, there is very strong dispersion effect to light,
Ultraviolet radiation can be absorbed simultaneously, so as to protect plastic polymer, prevents its light degradation, there are long-time stability, is absorbed purple
Outer light and prevent under ultraviolet light article fade etc. performance, so as to improve the resistance to ag(e)ing of plastics meter case and chemically stable
Property, extend its service life, in addition, also improving the weatherabilities such as the cold and hot aging of meter case, hydrothermal aging and salt fog aging
Energy.
