Abstract

Described are a method and agents designed to provide objects which come into contact with sea or brackish water with protection against fouling, the agents containing a benzothiophene-2-carboxamide-S,S-dioxide as the essential component.

Description

Benzothiophene-2-carboxamide-S.S-dioxide for antifouling use

The present invention relates to a method and means for protecting against the growth of objects, in particular hulls, screens, nets,

Buildings, quay systems, signal systems which come into contact with sea or brackish water.

Overgrowth by species from the Lepadomorpha group (barnacles), such as various Lepas and Scalpellum species, or by species from the Balanomorpha group (barnacles), such as Baianus or Pollicipes species, increases the frictional resistance of ships and consequently leads to increased resistance Energy consumption and frequent dry dock stays for a significant increase in operating costs.

In addition to the growth by algae, for example Ectocarpus sp. and Ceramium sp., vegetation by sessile Entomostraken groups, which are grouped under the name Cirripedia (tendril crayfish), is particularly important.

Benzothiophene-2-carboxamide-S, S-dioxide (BCD's), a process for their preparation and their fungicidal activity are known (DE-A-41 15 184). Above all, their effectiveness against fungi and harmful plants is described

Dermatophytes. Furthermore, it is stated that BCDs are suitable for protecting technical materials against microbial change or destruction.

EP 593 135 discloses their use for the finishing of mold-resistant emulsion paints.

It has now surprisingly been found that BCDs not only detect the types of mold that usually grow on paints, but also have an excellent antifouling effect.

The BCD's in their use in antifouling agents furthermore contain the usual constituents as e.g. in Ungerer, Chem. Ind. 37 (1985), 730-732 and Williams, Antifouling Marin Coatings 1973, Park Ridge: Noyes 1973.

Antifouling agents therefore contain, in addition to the active substances mentioned or their combinations, in particular binders.

Examples of recognized binders are polyvinyl chloride in a solvent system, chlorinated rubber in a solvent system, acrylic resins in a solvent system, in particular in an aqueous system, vinyl chloride / vinyl acetate copolymer systems in the form of aqueous dispersions or in the form of organic solvent systems, butadiene / styrene. Rubbers, butadiene / acrylonitrile rubbers, butadiene / styrene / acrylonitrile rubbers, drying oils, such as linseed oil, asphalt and epoxy compounds, resin esters or modified Hard resins in combination with tar or bitumen, small amounts of chlorinated rubber, chlorinated polypropylene and vinyl resins.

The antifouling agents may also contain inorganic pigments, organic pigments or dyes, which are preferably insoluble in seawater. Furthermore, the antifouling agents can contain materials, such as rosin, in order to enable controlled release of the active substances or the active substance combinations. The antifouling agents can also contain plasticizers, modifying agents which influence the theological properties and other conventional constituents. The compounds of the formula (I) or combinations mentioned at the outset can also be incorporated into self-polishing antifouling systems.

The BCD's are preferably present in the antifouling agent in concentrations of 1 to 20% by weight.

The means according to the invention advantageously make it possible to replace the previously available means with more effective ones. They show good stability and advantageously have a broad spectrum of activity.

example 1

A 2% solution of N-cyclohexyl-benzothiophene-2-carboxamide-S, S-dioxide is added in various dilutions to the still liquid mineral salt agar.

After the agar has solidified, an additional 1 ml of the liquid mineral salt medium is pipetted onto the agar and the plates are inoculated with the alga Oscillatoria tenuis. After 2 weeks of incubation at room temperature and light irradiation, the growth of the algae was rated.

No algae growth could be detected at concentrations above 20 ppm.
