Waterproofing agent |
摘要 |
<p>A cable grade waterproofing agent made of a crosslinked polymer produced by polymerizing a monomer mixture comprising at least one (meth)acrylic compound selected from the group consisting of (meth)acrylic acids and (meth)acrylic salts and a (meth)acrylamide in a molar ratio of said (meth)acrylic compound to said (meth)acrylamide in the range of from 1 : 9 to 5 : 5, said cross-linked polymer exhibiting a speed of absorption of not more than 8 minutes as expressed by the time required for the absorption of artificial seawater to reach 90% of the maximum, a capacity for absorption of said artificial seawater of not less than 8 times the own weight, and a gel viscosity in the range of from 0.6 x 10<5> to 2.5 x 10<5> dyne.s/cm<3>, and a composite waterproofing material carried on a substrate such as yarns and tape.</p> |
