Summary of the invention
In order to solve the technology technical problem that not only requires to insulate but also must the fire-resistant waterproof sealing, the invention provides a kind of composite flame retardant insulation water-proof seal adhesive tape and preparation method thereof.
The invention provides a kind of is that fire retardant insulating resilient material A and internal layer are fire-retardant water-tight self adhesive material B by skin, through rolling the compound composite flame retardant insulation water-proof seal adhesive tape of making.Component and the proportioning (parts by weight) of outer fire retardant insulating resilient material A are: 30~50 parts of terpolymer EP rubber EPDM4045,40~60 parts of chlorinatedpolyethylenees (CPE), 10~20 parts in flyash, 8~15 parts in sticking machine oil, 10~15 parts of decabromodiphenyl oxides, 10~15 parts of pentabromotoluenes, 6~10 parts of weisspiessglanzs, 3~8 parts of carbon blacks, 3~8 parts in paraffin, 1~3 part of stearic acid, 0.5~2 part of anti-aging agent RD, 0.5~1.5 part of antioxidant 1010,1~3 part of TM monex TD.Component and the proportioning (parts by weight) of the fire-retardant water-tight self adhesive material of internal layer B are: 20~30 parts of polyisobutene, 18~22 parts of terpine resins, 32~38 parts of isoprene-isobutylene rubbers, 3~5 parts of carbon blacks, 10~20 parts of fine particle calcium carbonates, 0.8~2 part of stearic acid.
The preparation method of composite flame retardant insulation water-proof seal adhesive tape is:
After the constitutive material of outer fire retardant insulating resilient material A taken by weighing by proportioning, place in the mill,, mixingly repeatedly take off up to molten fully good mixing in 140~160 ℃; Place on 130 ℃ of tri-roll press machines, adjusting the roller spacing is 0.1~0.3cm again, rolls and be cut into the band of the wide 5cm of being or other specifications with the 1m/min speed drawing.
After the constitutive material of the fire-retardant water-tight self adhesive material of internal layer B taken by weighing by proportioning, under the normal temperature on the machine of beginning to pratise mixing and be cut into rectangularly, at room temperature place forcing machine to extrude then; Notice that forcing machine adopts special mouthful of mould, export the thick 0.1~0.3cm of being of sheet material to reach, wide is the band of 5cm or other specifications.Certainly, the width of cladding material A and inner layer material B and length should be consistent with each other.
At last above-mentioned cladding material A and inner layer material B are rolled compoundly on tractor, make composite flame retardant insulation water-proof seal adhesive tape.Then, can cut and grow into 300cm or other specification length, invest on the internal layer with interleaving paper again, roll up with winder.
Composite flame retardant insulation water-proof seal adhesive tape of the present invention twines cable or other electric power facility that needs processing with 1/2 or 1/3 width overlap joint when using, can stretch 30%~50% during winding.Composite flame retardant insulation water-proof seal adhesive tape of the present invention has good " conformal performance ", is easy to stretch to twine, and need not do anyly to tie up processing and can form the extruding contraction effect.Especially very convenient for the coating of the irregular joint of geometrical shape.Waterproof and dampproof, insulated enclosure.Flame retardant properties is good, can be used for no open flames and requires fire-retardant particular surroundings, and oxygen index can reach 28.Its outer substrate intensity is good, has remedied the defective of internal layer seal gum intensity difference.This composite flame retardant insulation water-proof seal adhesive tape compare with the heat-shrinkage material adhesive tape have simple to operate, without naked light, advantages such as " conformal performance " is strong have solved the flame retardant insulation water-proof seal technical problem of the following various electric power facility joints of 10KV, are with a wide range of applications.
