Abstract
The invention discloses a semi-flexible PVC elastic sheath. According to a formula, the semi-flexible PVC elastic sheath comprises 75 g of PVC SG-3, 45 g of activated carbon, 45 g of DOP, 3 g of DOS, 20 g of chlorinated paraffin, 2.8 g of a stabilizer, 0.6 g of stearic acid, 9 g of MBS, and 1 g of paraffin. The semi-flexible PVC elastic sheath has good high temperature resistance and ageing resistance, and can adapt to high temperature caused by overload or short circuit during the use of power cables, and the materials have high insulating strength and volume resistivity; the sheath is good in flexibility, high in compressive strength, and resistant to non-uniform settlement, and is not required to encapsulate concrete in a construction site; the friction coefficient of the surface of the inner wall of the heath is small, the sheath is convenient to use, and the service life of the sheath is long.
Description
Technical field
The present invention relates to cable shoe, be specifically related to a kind of half flexible PVC flexible 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 half flexible PVC flexible sheath 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 PVC tri-type 75g, gac 45g, DOP45g, DOS3g, the cured 20g of chlorine, stablizer 2.8g, stearic acid 0.6g, MBS9g, paraffin 1g are made.
As preferably, described softening agent is DINP.
As preferably, described stablizer comprises photostabilizer and thermo-stabilizer.
As preferably, described photostabilizer is UV light absorber.
As preferably, described thermo-stabilizer is calcium agent.
As preferably, described thermo-stabilizer is metal soap.
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: half flexible PVC flexible sheath, and its formula is PVC tri-type 75g, gac 45g, DOP45g, DOS3g, the cured 20g of chlorine, stablizer 2.8g, stearic acid 0.6g, MBS9g, paraffin 1g are made.
It should be noted that described softening agent is DINP.
It should be noted that described stablizer comprises photostabilizer and thermo-stabilizer.
It should be noted that described photostabilizer is UV light absorber.
It should be noted that described thermo-stabilizer is calcium agent.
It should be noted that described thermo-stabilizer is metal soap.
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.
