(57) [Summary] [Structure] 2-Ethylhexyl acrylate 97 parts by weight, Acrylic acid 3 parts by weight, total amount of all monomers in a weight ratio to ethyl acetate, total monomer / ethyl acetate = 55/4 The resulting solution was dissolved in ethyl acetate to give 5 and 0.062 parts by weight of benzoyl peroxide was added as a polymerization initiator to the resulting solution. The mixture was refluxed under nitrogen at 80 ° C. for 8 hours. Polymerization was performed by stirring for a time to obtain an acrylic copolymer solution, and then 20 parts by weight of hydrogenated rosin pentaerythritol ester (softening point 105 ° C.), hydrogenated petroleum resin (softening point 145 C.) and finally 0.1 part by weight of HDU. [Effect] Between the existing strips for pipe lining and the metal plate that can generate marine organism repellent components by reacting with seawater, which has excellent initial adhesion properties and excellent durability after immersion in salt water. Can be suitably used as an adhesive for adhering |
