Mixing material injection insulating sleeve of electric pipe mold is made by condensation material using Shooting Technique.
The mixing material includes that weight is 60%~70% polyvinyl chloride, 5%~10% basalt fibre, 1%~2%
Silica, 15%~30% plasticizer and 1%~2% carbon fiber, after mixing material stirs evenly, at 120 DEG C~180 DEG C
Temperature and the MPa of 90MPa~110 injection pressure under, be injected into ferrule mold, cooling forming.
When the mixing material sprue bushing mold, the temperature of ferrule mold is 40 DEG C~70 DEG C.
The basalt fibre is the chopped yarn of basalt fibre, and the length for the yarn that is chopped is not more than 1mm, and diameter is not more than 9nm.
The invention has the benefit that electrical isolation casing provided by the invention, using polyvinyl chloride and basalt fibre
Mixing material, basalt fibre are a kind of with electrical isolation, corrosion-resistant, high temperature resistance fibrous material, and it is fine that basalt is added
Dimension can increase the high temperature resistance of electrical isolation casing, increase by 30% or more than traditional electrical isolation casing high temperature resistant, increase electricity
The adaptation range of insulating sleeve；Production process is simple, and cost is relatively low, is conducive to the popularization and use of electrical isolation casing.
