Mica, is a sheet of inorganic mineral material, which is characterised by insulation, high temperature resistance, glossy, stable physico-chemical properties, good thermal insulation, elasticity and toughness and non-combustibility, and has the property of being stripped into a transparent sheet with elasticity.
Mica tape is made from flakes of mica powder into mica paper, which is adhered to glass fibre cloth with adhesive.
The glass cloth pasted on one side of the mica paper is called "single-sided tape", and the tape pasted on both sides is called "double-sided tape". In the manufacturing process, several structural layers are bonded together, then dried in an oven, rolled, and slit into different sizes of tapes.
A kind of organosilicon adhesive for refractory mica tape and its preparation method. It consists of the following components reacted in mass ratio: hydroxy silicone rubber 1; organosilicone resin 1.0~3; organic solvent 1.5~3; condensation catalyst 0.00005~0.001. wherein the main chain link of the organosilicone resin is R
Fire-resistant mica tape is a kind of fire-resistant insulating material, which is wrapped on the surface of the cable to ensure the normal work of the equipment system in the special accident and make the staff escape from the scene of the accident with the fastest speed. Fire-resistant mica tape as a fire-resistant cable in the main insulation layer plays the most important role, the composition of the fire-resistant mica tape materials are mica paper, glass fibre cloth, adhesive, which mica paper is the real fire-resistant insulating role of the material, the glass fibre cloth is belong to the reinforcing material, so that the fire-resistant mica tape has enough strength, and adhesive will be the combination of the mica paper and the glass fibre cloth as a whole. The selection of adhesive must meet the high bond strength between mica paper and glass fibre cloth; mica tape has a certain degree of flexibility and edge
curvature, and the inorganic content of the adhesive, i.e., the si/r ratio should be large; the amount of charcoal residue after combustion should be low, i.e., combustion is not the principle of carbonisation, and one of the three can not do without the other. Burning is not carbonised is crucial, it directly affects the insulation resistance of the mica tape after combustion, silicone adhesive combustion generates white powder sio2, sio2 has good electrical insulation properties, so the
silicone adhesive for the fire-resistant mica tape is the most ideal adhesive.
