Problems solved by technology

Therefore, when replacing the used adhesive tape with a new adhesive tape, it is difficult to easily peel it off manually.
In addition, in addition to the problem of very high adhesive force, since the base material is a metal plate, once the used adhesive tape is peeled off, the base material will be plastically deformed, and the reusability during construction is insufficient.

Embodiment

[0124] Hereinafter, the present invention will be specifically described through examples, but the present invention is not limited in any way by these examples.

[0125]

[0126] According to JIS7161, JIS7162, JIS7127, use a tensile testing machine (AUTOGRAPH AGS-X, produced by Shimadzu Corporation) and analysis software (TRAPEZIUM X, produced by Shimadzu Corporation) to measure the elongation and elongation of the substrate layer Stress at the breaking point.

[0127]

[0128] The adhesive of the adhesive layer was transferred onto a polyester film (trade name "S-10", manufactured by Toray Co., Ltd., thickness 38 μm) using a hand roller to obtain an adhesive sheet with a substrate. Cut it into a test piece size of 80mm×20mm. A plastic FRP board reinforced with a glass cloth in an epoxy resin of 30 mm × 100 mm × thickness 2 mm as an adherend was used. The test piece was reciprocated once on the adherend with a 2 kg roller to stick it on the adherend, and after leaving it at 23°C...

Abstract

Provided is an adhesive tape for preventing adhesion by aquatic organisms which exhibits favorable adhesion underwater, has favorable mechanical properties, is easily detachable, can maintain an antifouling effect for the long term, has a light burden on people and the environment, is lightweight, can retain a stable quality, and can effectively prevent adhesion by aquatic organisms. Furthermore, it is preferable for the provided adhesive tape for preventing adhesion by aquatic organisms to require little labor to detach, to exhibit minimal plastic deformation of the substrate thereof when detaching, and to exhibit excellent reworkability when being applied. This adhesive tape for preventing adhesion by aquatic organisms is an adhesive tape including an antifouling layer, a substrate layer and an adhesive layer in this order, wherein the antifouling layer contains a silicone resin.

Description

Technical field [0001] The present invention relates to an adhesive tape preventing the attachment of aquatic organisms. In detail, the present invention relates to preventing aquatic organisms from adhering to underwater structures (ships, navigation aids, harbor equipment, offshore oil field equipment, waterways for cooling water in power plants, waterways for cooling water in factories, floating passages on the water, etc.) Adhesive tape to prevent the attachment of aquatic organisms. Background technique [0002] Ships and other underwater structures are in contact with seawater. Barnacles, oysters, blue mussels, hydroids, ascidians, ascidians, bryozoans, green algae, green sea vegetables, attached diatoms and other marine organisms attach and multiply, causing A bad condition such as a decrease in the mechanical performance of the equipment such as an increase in fluid resistance or a decrease in thermal conductivity, or the spread of attached marine organisms overseas. In...
