Abstract
The invention provides an insulation material for a cable joint, which comprises the following components in weight percent: 55-70% of epoxy resin, 15-23% of curing agent, 6-11% of glass fiber, 5-10% of polyethylene reagent and 1-7% of additive. The insulation material of the invention has excellent forming ability, and the material quality is uniform after the insulation material is formed. By detection, the insulation resistance between cables of a cable joint device adopting the insulation material fully meets the requirement of the insulation strength required for the power engineering, the flame resistance of the insulation material reaches V0 level, and simultaneously, the manufacturing cost is very low.
Description
Technical field
The present invention relates to a kind of insulating material, relate in particular to a kind of insulating material that is used for cable splice.
Background technology
Existing insulating material mainly contains rubber, polyethylene and Resins, epoxy.It is relatively stable that elastomeric material has chemical property, the insulation strength advantages of higher, but this material require high-temperature shaping has brought inconvenience to site operation; Polythene material has good flame resistance, and plasticity-is strong, be convenient to advantages such as in-situ casting typing, but this material insulation property is poor; Resins, epoxy has excellent chemical stability, and the performance of multiple dielectric corrosion such as alkaline-resisting, sour, salt is good, characteristics such as good flame resistance, but this material require cooperates accordingly and could finalize the design.
In actual applications, above-mentioned three kinds of materials all can not satisfy the requirement of cable connector device insulating, and therefore, seeking a kind of perfect insulating material is that those skilled in the art are devoted to one of technical problem that solves always.
Summary of the invention
Purpose of the present invention provides a kind of insulating material that is used for cable splice exactly in order to address the above problem, this insulating material can satisfy the insulating requirements of existing cable piecing devices fully.
The object of the present invention is achieved like this:
The invention discloses a kind of insulating material that is used for cable splice, form by following components in weight percentage:
Resins, epoxy 55～70%
Solidifying agent 15～23%
Glass fibre 6～11%
Polyethylene reagent 5～10%
Additive 1～7%
Described additive is a mica powder.
The shared weight percent of described Resins, epoxy is 58～61%.
The shared weight percent of described solidifying agent is 19～22%.
The shared weight percent of described glass fibre is 7～8.5%.
The shared weight percent of described polyethylene reagent is 6.5～8%.
The shared weight percent of described additive is 4.5～5.5%.
The starting material that adopted among the present invention all can be purchased from market and obtain.
Insulating material forming ability of the present invention is good, material is even after the moulding, adopts the cable connector device of this insulating material after testing, and the insulation resistance that its cable is alternate satisfies the requirement of the required insulation strength of power engineering fully, its flame retardant resistance reaches the VO rank, and cost of manufacture is very cheap simultaneously.
Embodiment
The following examples can make those skilled in the art more fully understand the present invention, but do not limit the present invention in any way.
Embodiment 1
The solidifying agent of 58 parts by weight of epoxy resin, 21 weight parts, the glass fibre of 8 weight parts, the polyethylene reagent of 6 weight parts and the mica powder of 7 weight parts are mixed, be poured in the cable splice typing after, promptly obtain required cable connector device.
Embodiment 2
The solidifying agent of 59 parts by weight of epoxy resin, 20 weight parts, the glass fibre of 8 weight parts, the polyethylene reagent of 7 weight parts and the mica powder of 6 weight parts are mixed, be poured in the cable splice typing after, promptly obtain required cable connector device.
Embodiment 3
The solidifying agent of 60 parts by weight of epoxy resin, 19 weight parts, the glass fibre of 8 weight parts, the polyethylene reagent of 6 weight parts and the mica powder of 7 weight parts are mixed, be poured in the cable splice and finalize the design, promptly obtain required cable connector device.
Adopt 2500V insulation megger to detect the insulation resistance of prepared cable connector device among the embodiment 1-3, the result of gained is as follows:
Above-mentioned test-results shows that every insulation technology index of made sample among the embodiment 1-3 all meets the demands, excellent property, and cost of manufacture is cheap, simultaneously owing to added mica powder, its flame retardant resistance has also reached the VO rank, meets cable splice necessary requirement in the power engineering fully.
