摘要:
Pressure sensitive tape for anticorrosion steel pipe protection used primarily in cases of repair and maintenance, comprising vinyl base-tape laminated with a nitrile rubber-based adhesive of the following composition: about 30.7 to about 34.0% (w/w) solid butadiene acrylonitrile rubber (NBR); about 0.57 to about 0.63% (w/w) antioxidant; about 9.7 to about 12.9% (w/w) hydrocarbon resin; about 1.52 to about 1.68% (w/w) zinc oxide; about 8.7 to about 9.5% (w/w) liquid butadiene acrylonitrile rubber. (NBR); about 4.0 to about 4.4% (w/w) aluminium hydrosilicate; about 5.5 to about 7.5% (w/w) diisononyl phthalate; about 0.66 to about 0.74% (w/w) carbon black; about 1.5 to about 1.7% (w/w) amorphous silica; and about 25.8 to about 38.8% (w/w) magnesium and calcium carbonate. The tape exhibits a good ability to conform to irregular surfaces, good elasticity, good impact resistance, excellent pipe adhesion and good cathodic detachment. The tape is ideally used in conjunction with a primer that improves adhesion between the pipe and the adhesive portion of the tape.
