Description
Technical field
The utility model relates to a kind of mica tape, is specifically related to a kind of mica tape end connecting.
Background technology
Mica tape, claim again fire-resistant isinglass belt, is a kind of refractory insulating material, by purposes, can be divided into: mica tape, cable mica tape for motor.By structure, be divided into: double-sided belt, one-side band, three-in-one band, two film band, monofilm band etc.By mica, can be divided into again: synthetic mica tape, gold mica tape, white clouds master tape.
Fire-resistant safety cable mica tape is a kind of high performance mica insulation goods, has good resistance to elevated temperatures and flame resistance energy.There is good flexibility during the mica paper tape normality, be applicable to main refractory insulating layer in various fire-resisting cables.Substantially there do not is the volatilization of harmful smog when meeting the naked light burning, so this product is not only effective for cable, and also very safe.
Synthetic mica is to replace hydroxyl with fluorine ion, and the size synthesized under condition of normal pressure is large, the synthetic mica of complete in crystal formation.Synthetic mica tape is that synthetic mica is copied to the mica paper of making is main material, then with adhesive, glass fabric is sticked on to one or both sides and make.Glass fabric is sticked on to be called " one-side band " of mica paper one side, all paste on two sides is " double-sided belt ".In manufacture process, after several layer of structure are bonded together, then dry through stove, then rolling, then cut into the belt of different size.
Synthetic mica tape except the characteristic with natural mica band: the coefficient of expansion is little, dielectric strength is large, resistivity is high and dielectric constant evenly, its main feature is that thermal endurance class is high, can reach the fire-resistant level of A level (950 ~ 1000 ℃)
The synthetic mica tape heatproof is greater than 1000 ℃, and thickness range is at 0.08 ~ 0.15mm, and maximum is supplied width 920mm.
A, two-sided synthetic mica tape: take synthetic mica paper as base material, with glass fabric, make two-sided supporting material, bonding with silicon resin adhesive, be to manufacture the optimal preferred material of fire safe type electric wire.Fire resistance is best, recommends key project to use.
B, single face synthetic mica tape: take synthetic mica paper as base material, with glass-fiber-fabric, make the single-side reinforced material, is to manufacture the optimal preferred material of fire safe type electric wire.Fire resistance is good, recommends key project to use.
Gold mica tape: phlogopite series mica tape has good fire resistance, resistance to acids and bases and anti-corona, radiation-resistant characteristic, and fine flexibility and hot strength are arranged, and is suitable for high-speed coiling.Fire-resistant experiment shows: held the electric wire of gold mica tape, can guarantee not puncture in 90min hour under the condition of 840 ℃ of voltage 1000V of temperature.
Yet the length of mica tape is limited, be generally that mica tape is coiled into to dish, every dish only has 30 ~ 50m, and when reality is used, be wound around cable with mica tape, need tens meters of continuous windings to hundreds of rice, so just will inevitably need a few dish mica tapes are coupled together.In the prior art, the joint of mica tape is to adopt plastic adhesive tape to bond together.The joint bonding strength that adopts this connected mode to connect is low, and the thickness of linkage section is more than 2 times of mica tape self thickness, will have a strong impact on like this winding mass of mica tape.
The utility model content
The purpose of this utility model is to overcome the defect existed in prior art, provides a kind of linkage section firm, and the smooth mica tape end connecting of linkage section.
For achieving the above object, one of the technical solution of the utility model is a kind of mica tape end connecting of design, it is characterized in that, described mica tape comprises mica paper layer, layer of silica gel and glass fibre layer of cloth, one section in described mica tape end one side only retains mica paper layer, one section at described mica tape end opposite side only retains the glass fibre layer of cloth, between the glass fibre layer of cloth of described mica tape end one side mica paper layer opposite side, scribbles layer of silica gel.
In order to guarantee the adhesive strength between mica paper layer and glass fibre layer of cloth, do not waste again silica gel simultaneously, also can effectively control the thickness of mica tape, preferred technical scheme is that the thickness of described layer of silica gel is 30g/m
2.
Intensity in order to ensure the mica tape joint area, can also complete rapidly the connection work of joint simultaneously, further preferred technical scheme is, described mica tape end one side only retains the length of one section of mica paper layer, with described mica tape end opposite side, only retains the 30mm ~ 60mm that is of one section of glass fibre layer of cloth.
Have enough intensity in order to ensure mica tape, the while is the cost of reduce mica tape again, and further preferred technical scheme also has, and the warp density of described glass fibre layer of cloth is 26/cm, and the weft density of described glass fibre layer of cloth is 12/cm.
In order further to strengthen the insulation effect of mica tape, the reduction of the insulation effect of avoiding mica tape to cause through moisture, further preferred technical scheme also has, and at the one or both sides of described mica tape, is attached with plastic membranous layer.
Advantage of the present utility model and beneficial effect are: the joint design of this mica tape, by by one section of joint one end removal mica paper layer, by one section of joint other end removal glass fibre layer of cloth, and then bonds together the two ends after processing with silica gel.This joint connecting structure has and is connected firmly, and connecting portion is smooth, and after connecting, the thickness of the thickness of joint area and mica tape is basic identical.The method of attachment of this joint has the characteristics such as simple to operate, quick, firm and good looking appearance.
The accompanying drawing explanation
Fig. 1 is the utility model mica tape end connecting schematic diagram;
Fig. 2 is the structural representation before Fig. 1 does not connect.
