<p>The present invention relates to a moistureproofing or moisture permeable sealing tape for windows. The moistureproofing tape of the present invention is manufactured by mixing i) 20-30 parts by weight of 2-hydroxyethyl methacrylate, ii) 30-40 parts by weight of benzyl acrylate and iii) 35-45 parts by weight of pentaerythritol triacrylate based on the whole weight of copolymers with a reaction solvent under nitrogen atmosphere, increasing temperature in order to reach 110-130°C, performing polymerization by inserting the polymerization initiator into a mixture after melting a polymerization initiator in the reaction solvent and coating a non-woven fabric with a copolymer coating solution. The moistureproofing tape is manufactured by mixing i) 45-55 parts by weight of 2-hydroxyethyl methacrylate, ii) 30-40 parts by weight of benzyl acrylate and iii) 10-20 parts by weight of pentaerythritol triacrylate based on the whole weight of copolymers with a reaction solvent under nitrogen atmosphere, increasing temperature in order to reach 110-130°C, performing polymerization by inserting the polymerization initiator into a mixture after melting a polymerization initiator in the reaction solvent and coating a non-woven fabric with 0.2-0.5 parts by weight of copolymers and foaming agents.</p> |
