Abstract

The invention discloses a rare earth wire shielded PVC cable sheath which comprises the following raw materials: 60%-70% of PVC resin, 5%-10% of dioctyl phthalate, 2%-5% of a stabilizer, 2%-5% of a plasticizer, 2%-5% of an inorganic filler, 1%-3% of a colorant, 2%-4% of a lubricant, 2%-5% of an antioxidant, and 1%-3% of other additives. The rare earth wire shielded PVC cable sheath has high high-temperature resistance and high ageing resistance, can adapt to high temperature generated due to overload or short-circuit in the use process of a power cable; the raw materials have high insulating strength and high volume resistivity; the flexibility is high, the compressive strength is high, differential settlement is resisted, and concrete does not need to be encapsulated on a construction site; the friction coefficient of the surface of the inner wall is low, the use is facilitated, and the service life of the rare earth wire shielded PVC cable sheath is long.

Description

A kind of rare-earth wires shielding PVC cable sheath
Technical field
The present invention relates to cable shoe, be specifically related to a kind of rare-earth wires shielding PVC cable sheath.
Background technology
Current engineering cable shoe is take polyvinyl chloride (PVC) RESINS as major ingredient, water-ground limestone is mixed for filler and the small powder such as chlorinatedpolyethylene, paraffin, and possess certain corrosion-resistant, high temperature resistant, fire-retardant, insulate the wear-resisting characteristic such as lightweight, pollution-free.But it is poor that its weak point is ultimate compression strength, require gap in addition with construction application, its flame retardant properties is also not ideal enough; Its vicat softening temperature is hovered at about 90 DEG C in addition, and inner and outer pipes wall friction coefficient is large, adds the difficulty of construction usage.
Summary of the invention
For the deficiency that prior art exists, the present invention seeks to the rare-earth wires shielding PVC cable sheath being to provide a kind of excellent property.
To achieve these goals, the present invention realizes by the following technical solutions: its raw material is made by other auxiliary agents of the tinting material of the inorganic filler of the softening agent of the stablizer of the o-benzoic acid dioctyl ester of the polyvinyl chloride (PVC) RESINS of 60%-70%, 5%-10%, 2%-5%, 2%-5%, 2%-5%, 1%-3%, the lubricant of 2%-4%, the oxidation inhibitor of 2%-5% and 1%-3%.
As preferably, described softening agent is phosphoric acid ester.
As preferably, described inorganic filler is mica.
As preferably, described lubricant is soybean oil.
As preferably, described stablizer is aluminium salt.
As preferably, described stablizer is dibasic hard acid aluminium.
Product of the present invention has high temperature resistant and ageing resistance is good, and can adapt to the high temperature that power cable use procedure produces because of overload short circuit, material has high insulation resistance and volume specific resistance; Flexible and ultimate compression strength is large, anti-non-uniform settling, need not pouring concrete be encapsulated at the construction field (site); Inner wall surface coefficient of friction is little, is beneficial to use, and product life is long.
The present invention is described in detail below in conjunction with embodiment.
embodiment
The technique means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
This embodiment is by the following technical solutions: rare-earth wires shielding PVC cable sheath, and its raw material is made by other auxiliary agents of the tinting material of the inorganic filler of the softening agent of the stablizer of the o-benzoic acid dioctyl ester of the polyvinyl chloride (PVC) RESINS of 60%-70%, 5%-10%, 2%-5%, 2%-5%, 2%-5%, 1%-3%, the lubricant of 2%-4%, the oxidation inhibitor of 2%-5% and 1%-3%.
It should be noted that described softening agent is phosphoric acid ester.
It should be noted that described inorganic filler is mica.
It should be noted that described lubricant is soybean oil.
It should be noted that described stablizer is aluminium salt.
It should be noted that described stablizer is dibasic hard acid aluminium.
Product of the present invention has high temperature resistant and ageing resistance is good, and can adapt to the high temperature that power cable use procedure produces because of overload short circuit, material has high insulation resistance and volume specific resistance; Flexible and ultimate compression strength is large, anti-non-uniform settling, need not pouring concrete be encapsulated at the construction field (site); Inner wall surface coefficient of friction is little, is beneficial to use, and product life is long.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
