Abstract
The invention discloses a low-temperature resistant high-strength PVC (Polyvinyl Chloride) cable protection sleeve. The low-temperature resistant high-strength PVC cable protection sleeve is prepared from the raw materials by weight: 100g of PVC SG-3, 50g of a plasticizer, 5g of epoxidized soybean oil, 8g of chlorinated paraffin, 5g of antimony oxide, 0.5g of an antioxidant, 5g of calcined argil, 10g of filler, 7g of a stabilizer, 3g of a photostabilizer, 30g of DOS and a proper volume of internal and external lubricants. The low-temperature resistant high-strength PVC cable protection sleeve disclosed by the invention has the advantages that the high-temperature resistance and ageing resistance are good, the product can adapt to high temperature resulting from overloaded short circuit during the use of a power cable, and a material has high insulation strength and volume resistivity; the product is good in flexibility and high in compressive strength and is resistant to uneven settlement, and cast concrete is not required to be enveloped at a construction site; the coefficient of friction of the surface of the internal wall is small, the use is facilitated, and the life of the product is long.
Description
Technical field
The present invention relates to cable shoe, be specifically related to a kind of PVC protective casing of low temperature resistant high-strength cable.
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 PVC protective casing of the low temperature resistant high-strength cable being to provide a kind of excellent property.
To achieve these goals, the present invention realizes by the following technical solutions: it is filled a prescription as PVCSG-3100g, softening agent 50g, epoxy soybean oil 5g, clorafin 8g, weisspiessglanz 5g, oxidation inhibitor 0.5g, calcinated argil 5g, filler 10g, stablizer 7g, photostabilizer 3g, DOS30g and appropriate inside and outside lubrication prescription are made.
As preferably, described softening agent is DOS.
As preferably, described photostabilizer is UV-5.
As preferably, described thermo-stabilizer is calcium carbonate.
As preferably, described softening agent is TOTM.
As preferably, described stablizer is calcium zinc mixture.
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: the PVC protective casing of low temperature resistant high-strength cable, and its formula is PVCSG-3100g, softening agent 50g, epoxy soybean oil 5g, clorafin 8g, weisspiessglanz 5g, oxidation inhibitor 0.5g, calcinated argil 5g, filler 10g, stablizer 7g, photostabilizer 3g, DOS30g and appropriate inside and outside lubrication prescription are made.
It should be noted that described softening agent is DOS.
It should be noted that described photostabilizer is UV-5.
It should be noted that described thermo-stabilizer is calcium carbonate.
It should be noted that described softening agent is TOTM.
It should be noted that described stablizer is calcium zinc mixture.
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.
