Abstract
The invention relates to a waterproof insulating rubber tape for electric cables. The waterproof insulating rubber tape comprises an ethylene-propylene rubber base layer, an insulating daub layer and release paper, wherein the lower end face of the ethylene-propylene rubber base layer and the upper end face of the insulating daub layer are laminated, the lower end face of the insulating daub layer and the release paper are laminated, and the insulating daub layer is prepared from electrical-grade daub. The waterproof insulating rubber tape for the electric cables is simple in structure and has damp-proofing and acid-base resisting properties; and through additionally arranging the insulating daub layer on the ethylene-propylene rubber base layer, the ethylene-propylene rubber base layer provides an important centripetal force for that daub flows to and fills each slit and gap of a cable sheath during the drawing of the rubber tape, so that very good damp-proofing and seal protecting actions are formed at joints or terminals.
Description
Technical field
The present invention relates to cable waterproof insulation tape, belong to insulation tape technical field.
Background technology
Insulation tape is that electrician is leaked electricity for preventing, and plays the adhesive tape of insulation effect, forms primarily of base band and pressure-sensitive adhesive layer. Base band generally adopts cotton, synthetic fabrics and plastics film etc., and glue-line is added the Synergist S-421 95s such as tackifying resin and makes by rubber, and viscosity is good, and insulating property are excellent, is applicable to the features such as electric wire is plugged into, electric insulation protection.
In the major insulation of some solid dielectric power cable connector and end; owing to its fracture or breach exist gap; make general waterproof insulation tape well cannot form the protection of good moisture sealed at joint or end, thus cause waterproof sealing effect poor.
Summary of the invention
For above-mentioned defect, it is an object of the invention to provide a kind of structure simple, there is protection against the tide and anti acid alkali performance, it is possible to play the cable waterproof insulation tape of fine waterproof insulation effect.
The technical solution adopted in the present invention is for this reason:
Comprising ethylene-propylene rubber(EPR) basic unit, insulation clay layer and separate-type paper, the upper surface laminating of described ethylene-propylene rubber(EPR) basic unit lower surface and insulation clay layer, the lower surface of described insulation clay layer and separate-type paper laminating, described insulation clay layer is electric level clay.
The thickness of described ethylene-propylene rubber(EPR) basic unit is 0.5-2mm.
The thickness of described insulation clay layer is 1-2mm.
The thickness of described separate-type paper is for being 0.5-1mm.
It is an advantage of the invention that:
Present configuration is simple; there is protection against the tide and anti acid alkali performance; by setting up insulation clay layer in ethylene-propylene rubber(EPR) basic unit; in adhesive tape drawing process; ethylene-propylene rubber(EPR) basic unit is that clay flows to and is filled to cable sheath gap, each place and breach provides important centripetal force, thus forms good moisture sealed provide protection at joint or end.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure, 1 to be ethylene-propylene rubber(EPR) basic unit, 2 be that insulation clay layer, 3 is separate-type paper.
Embodiment
Cable waterproof insulation tape, comprise ethylene-propylene rubber(EPR) basic unit 1, insulation clay layer 2 and separate-type paper 3, the upper surface laminating of described ethylene-propylene rubber(EPR) basic unit 1 lower surface and insulation clay layer 2, lower surface and the separate-type paper 3 of described insulation clay layer 2 are fitted, and described insulation clay layer 2 is electric level clay.
The thickness of ethylene-propylene rubber(EPR) basic unit 1 of the present invention is 0.5-2mm.
The thickness of insulation clay layer 2 of the present invention is 1-2mm.
The thickness of separate-type paper 3 of the present invention is for being 0.5-1mm.
