Abstract
The invention discloses a high-elasticity synthesized PVC cable sheath. The high-elasticity synthesized PVC cable sheath comprise the following raw materials: 60-70% of polyvinyl chloride 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 coloring agent, 2-4% of a lubricating agent, 2-5% of an antioxidant, and 1-3% of other additives. The product is good in high temperature resistance and ageing resistance, and can be adapted to the high temperature caused by overload or short circuit in the power cable using process; the materials are high in insulating strength and high in volume resistivity; the product is good in flexibility, high in compressive strength, and differential settlement resistant; the on-site concrete is not required to be encapsulated on the construction site; the high-elasticity synthesized PVC cable sheath is low in wall surface friction coefficient, facilitates being used, and is long in service life.
Description
Technical field
The present invention relates to cable shoe, be specifically related to a kind of PVC cable sheath of high-elastic synthesis.
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 cable sheath of the high-elastic synthesis 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 KM31 powder.
As preferably, described lubricant is silicone oil.
As preferably, described stablizer is metal soap.
As preferably, described stablizer is calcium laurate.
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 cable sheath of high-elastic synthesis, 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 KM31 powder.
It should be noted that described lubricant is silicone oil.
It should be noted that described stablizer is metal soap.
It should be noted that described stablizer is calcium laurate.
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.
