FLOATING STRUCTURE

Japanese Patent JPH01314689

A

PURPOSE:To manufacture a degradation-retardant floating body economically and to prevent contamination of ocean or lake by forming a composition composed of at least one binder for binding material having bulk specific gravity lower than 0.8 and the diameter of particle in the range of 10-2,000mu into a desired shape. CONSTITUTION:A material having bulk specific gravity lower than 0.8 and the diameter of particles in the range of 10-2,000mu and filite 200/7 are employed while epoxy resin added with denatured polyamine as hardener is employed as a binder. The filite and the binder and mixed uniformly and filled in a cylindrical mold with a foam styrole being regulated to a predetermined position, then it is cured for eight hours and taken out from the mold thus forming a composition 1 by 1-50mm around the foam styrole 2. The composition 1 has higher durability, mechanical strength and excellent weather resistance and impact resistance when compared with the foam styrole 2, and the floating force thereof increases due to decreased specified gravity. Furthermore, broken portion sinks through permeation of water thus preventing floating on the water face.
