Abstract
The invention discloses a reinforced type silicon rubber self-adhesion insulated rubber tape. Cotton fiber cloth is taken as a base material and adhesive layers are respectively coated on upper and lower faces. Each adhesive layer comprises the following materials in parts by weight: 30-60 parts of silicon rubber, 10-25 parts of gas-phase white carbon black, 0-5 parts of silicone oil softening agent, 5-20 parts of silicon-boron tackifier, 0.2-0.5 part of coloring agent and 0.5-5 parts of vulcanizing agent. According to the reinforced type silicon rubber self-adhesion insulated rubber tape, the breaking strength is more than or equal to 5 MPa and the definite elongation strength is more than or equal to 3 MPa; when the reinforced type silicon rubber self-adhesion insulated rubber tape is used for an insulating, sealing and winding process of various cable connectors under 35 kV or below, the safety operation capability, the anti-cracking capability, the anti-fouling capability and the wear-resisting capability of cables are improved, the winding is more tight and the sealing waterproof effect is better; and the use is safe and reliable at a temperature rangoffing from -40 DEG C to 260 DEG C, and the anti-current-leakage capability is further improved.
Description
Technical field
The present invention relates to a kind of electric insulation material, the silicon rubber self-adhesive insulating tape that especially a kind of cable splice is used.
Background technology
Common self-adhesive insulating tape mainly contains two classes at present, one class is the High-Voltage Insulation string rubber of being fitted and being formed by two kinds of sheet rubbers, be divided into elastic insulating layer and adhesive coating, another kind of is to be the main self-adhesive rubber band of making by isoprene-isobutylene rubber, sclerosis forfeiture viscosity easily occurs in this two classes adhesive tape mostly under the long term high temperature environment, the pure silicon rubber insulation adhesive tape that occurs at present at short notice can be high temperature resistant, but the increase along with the time, its insulation level can descend, and cause insulated coil to damage, thereby work-ing life still can't prolong, the environment that a few thing temperature is higher, existing insulation tape can't meet the demands.
Summary of the invention
Purpose of the present invention is exactly in order to overcome the above problems, and provides a kind of high and low temperature environment that the reinforced silicon rubber self-adhesive insulating tape of Reliable guarantee all can be provided.
The reinforced silicon rubber self-adhesive insulating tape of the present invention is take cotton fiber cloth as base material, and upper and lower faces is coated with respectively adhesive layer.
Its mixing ratio by weight of the material of adhesive layer is as follows: silicon rubber 30-60 part, gas-phase silica 10-25 part, silicone oil tenderizer 0-5 part, silicon boron tackifier 5-20 part, tinting material 0.2-0.5 part, vulcanizing agent 0.5-5 part.
Silicon rubber is 110,110-2 or 107 methyl vinyl silicone rubbers.
The silicone oil tenderizer is hydroxy silicon oil.
Vulcanizing agent is two two or five vulcanizing agents.
As a kind of improvement, the warp direction of cotton fiber cloth is that S shape is crooked.
The production method of insulation tape of the present invention: with silicon rubber, gas-phase silica, silicon boron tackifier, vulcanizing agent by proportioning mix add carry out in the open mixing roll mixing, add silicone oil tenderizer, tinting material, drop in the glue melting box and play glue, be applied to that the base material two sides is laggard to be entered the microwave vulcanizing plant and vulcanize, then curling, cut and get final product.
The reinforced silicon rubber self-adhesive insulating tape of the present invention is take cotton fiber cloth as framework material, two sided coatings be with sticking silicone rubber compounds, form the self-adhesive insulating tape of three-decker, thereby greatly strengthened the intensity of insulation tape, tensile strength at yield 〉=5PMa, tensile modulus 〉=3MPa, in the wrapped process of insulated enclosure that is used for 35KV and following various cable splices, improved the safe operation ability of cable, the freedom from cracking ability, anti-pollution ability and wear resistance, wrapped tightr, sealed waterproof effect is better, use safety and reliability in high low temperature-40 ℃～260 ℃ of temperature ranges, anti-electric leakage ability further improves.In addition, warp direction be the bending of S shape cotton fiber cloth so that insulating tape only can stretch along warp direction, very little along weft direction deformation.
Description of drawings
Figure 1 shows that warp direction is the synoptic diagram of the cotton fiber cloth of S shape bending.
