Abstract

PURPOSE:To provide an underwater paint compsn. which has excellent antifouling properties and little toxicity and is suitable for use in marine structure, vessel, fishing facilities, etc., by dispersing a cured compsn. of an alkali metal silicate in a paint base using an org. high-molecular material as a vehicle. CONSTITUTION:An aq. soln. of an alkali metal silicate of the formula (wherein M is potassium, sodium, lithium, quaternary ammonium ; n is 0.5-8) is cured by adding a hardener such as magnesium oxide, calcium oxide or metallic zinc, dried and crushed into a powder of 150 mesh size or below, thus forming cured compsn. powder of the alkali metal silicate. 10-300wt% (based on the quantity of org. high-molecular material) said cured compsn. powder is blended with a paint base composed of an org. solvent soln. or an aq. emulsion (which may contain filler, dispersant, pigment, etc.) of an org. high-molecular material such as epoxy resin or polyurethane resin to obtain the desired underwater paint compsn.

In the field, there is a risk of a decrease in the moving area and clogging of the screen due to biological deposits on the inner surface of the pipe.

Because of this, the impact on the surrounding environment is minimal. For example, X'1. The antifouling agents that are used are toxic and dangerous, such as copper oxide and tin compounds. The inventors of the present invention have carried out various studies with the aim of providing an underwater antifouling paint composition that can solve these problems. (The present invention has been completed by deriving a high level of safety and having the ability to protect biological organisms.) The powder of the composition obtained by curing an alkali silicate aqueous solution as a curing agent is dispersed (this is an underwater coating composition).
