Description
Technical field
This utility model relates to mica tape technical field, is specifically related to a kind of heat radiation fire-resistant isinglass belt.
Background technology
Fire-resistant isinglass belt is made up of Muscovitum, supporting material and silicone sealants and the big material of additive three, it is by glass fabric or plastic sheeting and mica powder or synthetic mica, through the insulating material that fire resistant resin glue dip bonding is made, its nominal thickness, from 0.05mm to 0.18mm, with banding, becomes to open or the supply of material of rolling soft condition.Wherein mica paper is made up of mica splitting or mica powder watery distension method technique.According to the difference of constituent, mica paper has white mica, phlogopite and fluorophologopite (being synthetic mica) three class.Glass fabric uses alkali-free glass wool to be made into, and has stronger pliability and tension stress, plays certain reinforcement and invigoration effect in electric wire.Silicone adhesive is a kind of colloid substance, silica flour and other Organic substances are bound up, and after solvent dilution, mica paper and glass cloth tape is produced good permeability, beneficially mica paper and the bonding of glass cloth.Under flame temperature, the Organic substance in silicone adhesive by decomposing and volatilization, eventually forms sintering shape silica flour together with part silica flour.But because phosphorus content is extremely low, even if silicone adhesive is after high temperature action, its residue still has higher electrical insulation properties, thus reaches insulation effect.
The moisture resistance of mica paper is poor, in moist environment, it is easy to water suction rotten, prior art there are some patents with the addition of thin film above mica paper, but thin film is easily degraded after long applied at elevated temperature, the bulk life time making cable reduces, and the thin film poor heat resistance of the materials such as PE, PET of using in prior art, the high heat of mica paper side distributes slower due to the cladding of thin film.Therefore, it is necessary to mica tape structure of the prior art is improved.
Utility model content
The purpose of this utility model is to overcome defect present in prior art, it is provided that a kind of hydrophobic and heat radiation fire-resistant isinglass belt of rapid heat dissipation.
For realizing above-mentioned technique effect, the technical solution of the utility model is: a kind of heat radiation fire-resistant isinglass belt, including mica paper and the first reinforcing material bed of material being arranged on mica paper at least side, passing through the first silicone resin layer between mica paper and the first reinforcing material bed of material bonding, the described first reinforcing material bed of material is dewatering microporous film layer.
In order to ensure that mica tape has excellent hot strength; preferably technical scheme is; the bonding second reinforcing material bed of material that is provided with of the second silicone resin layer is passed through in dewatering microporous film layer side, and the described second reinforcing material bed of material is selected from alkali-free glass cloth, ceramic fiber cloth, aromatic polyamide paper, dewatering microporous film layer, polyester non-woven fabric, washs the one that glass mixes in weaving cotton cloth.
Preferably technical scheme is that described dewatering microporous film layer is microporous teflon membran or hydrophobic polyimides microporous membrane.Microporous teflon membran smooth surface and hydrophobicity are good, and silicone rubber adhesive is coated in polyimides microporous membrane surface, obtain after solidification between hydrophobic polyimides microporous membrane and the first silicone resin layer bonding firmly.
Preferably technical scheme is, washs mixed the weaving cotton cloth of glass and is formed by warp thread polyester filament and the braiding of weft yarn glass fibre yarn.Wash glass to mix the pliability of warp-wise polyester filament of weaving cotton cloth and be better than weft yarn glass fibre yarn, same size wash that ripple is mixed weaves cotton cloth compared with alkali-free glass cloth, the former pliability is more suitable for the cladding of cable.
Preferably technical scheme is that described mica paper is the one in white mica paper, phlogopite paper and fluorophologopite paper.
Advantage of the present utility model and having the beneficial effects that:
This heat radiation fire-resistant isinglass belt layer structure is reasonable, and by using dewatering microporous film layer as reinforcement material layers, the micropore in reinforcement material layers contributes to increasing the radiating efficiency of mica tape, and hydrophobic material can avoid mica paper water suction rotten；Hydrophobic microporous film surface bonding interface area after treatment and between the first organic silica gel resin bed is relatively big, is not easily stripped.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model heat radiation fire-resistant isinglass belt embodiment 1；
Fig. 2 is the structural representation of embodiment 2；
Fig. 3 is the structural representation of embodiment 3.
In figure: 1, mica paper；2, dewatering microporous film layer；3, the first silicone resin layer；4, the second silicone resin layer；5, wash that glass is mixed weaves cotton cloth.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
Embodiment 1
As shown in Figure 1, the heat radiation fire-resistant isinglass belt of embodiment 1, including mica paper 1 and the first reinforcing material bed of material being arranged on mica paper 1 at least side, bonding by the first silicone resin layer 3 between mica paper 1 and the first reinforcing material bed of material, the first reinforcing material bed of material is dewatering microporous film layer 2.
Dewatering microporous film layer 2 is microporous teflon membran.Microporous teflon membran smooth surface and hydrophobicity are good, surface after treatment bonding with silicone resin layer closely.
Mica paper 1 is white mica paper.
Embodiment 2
As in figure 2 it is shown, the difference of embodiment 2 and embodiment 1 is, the bonding second reinforcing material bed of material that is provided with of the second silicone resin layer 4 is passed through in dewatering microporous film layer 2 side, and the second reinforcing material bed of material is similarly dewatering microporous film layer 2.
Two-layer dewatering microporous film layer 2 outside mica paper is hydrophobic polyimides microporous membrane.The dewatering process method of hydrophilic polyimides microporous membrane is: silicone rubber adhesive is coated in polyimides microporous membrane surface, obtain after solidification between hydrophobic polyimides microporous membrane and the first silicone resin layer bonding firmly.
