Abstract
The invention discloses a polyethylene framework semi-air insulating layer and high-flame-retardant PVC (Polyvinyl Chloride) cable sheath. The cable sheath is prepared from the following raw materials: 60-70% of PVC resin, 5-10% of dioctyl phthalate, 2-5% of stabilizer, 2-5% of plasticizer, 2-5% of inorganic filler, 1-3% of colorant, 2-4% of lubricant, 2-5% of antioxidant, 1-2% of impact modifier and 1-3% of other assistants. The cable sheath has good high temperature resistance and ageing resistance, can adapt to high temperature generated by an overloading short circuit in a use process of a power cable, has high insulating strength, high volume resistivity, good flexibility and high compressive strength, and is differential settlement resistant; concrete is not required to be enveloped on a construction site; and a friction coefficient of the surface of an inner wall is small, so that use is facilitated and the service life of the cable sheath is long.
Description
Technical field
The present invention relates to cable shoe, be specifically related to a kind of polyethylene backbone formula half air insulating layer, high flame retardant 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 polyethylene backbone formula half air insulating layer, the high flame retardant PVC cable sheath that are 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 lubricant 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%, 2%-4%, the oxidation inhibitor of 2%-5%, the anti-properties-correcting agent of 1%-2% and 1%-3%.
As preferably, described softening agent is phosphoric acid ester.
As preferably, described stablizer is one package stabilizer.
As preferably, described lubricant is silicone oil.
As preferably, described anti-properties-correcting agent is MBS.
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: polyethylene backbone formula half air insulating layer, high flame retardant PVC cable sheath, and its raw material is made by other auxiliary agents of the lubricant 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%, 2%-4%, the oxidation inhibitor of 2%-5%, the anti-properties-correcting agent of 1%-2% and 1%-3%.
It should be noted that described softening agent is phosphoric acid ester.
It should be noted that described stablizer is one package stabilizer.
It should be noted that described lubricant is silicone oil.
It should be noted that described anti-properties-correcting agent is MBS.
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.
