Description

Characteristic of the known technical solutions

According to the prior art, various substances or combinations of substances are known which are intended to prevent or limit the growth of aquatic organisms, as well as the infestation by various water parasites on the underwater surface of watercraft.

The known solutions are described in DD-PS 762235, 24332,44480,44920, 82379 and 117691 described i. They include special paints to which toxic additives are added.

DD-PS 762 235 describes antifouling underwater paints whose antibacterial effect of an unspecified toxic ingredient of Crotonenöl includes. Anti-fouling ship's floor paint on the basis of post-chlorinated polyvinyl chloride using finest copper flakes is described in DD-PS 24332. Here are added in a conventional manner poisoned and substantially water-impermeable coating colors copper particles with a degree of fineness of 1 to 140 · 10 ^-3 mm.

In DD-PS 44489 highly pigmented anti-corrosion primers are called, which include zinc oxide, but also copper and mercury compounds as a corrosion and anti-fouling paint. An antifouling underwater protective paint is called according to DD-PS 44920, by a content of resistant compounds of dithiocarbamic acid and its derivatives, in particular the salts of the general formula

where R is alkyl, alkylene, aryl or hydrogen and Me metals, preferably zinc, copper, manganese, as the active ingredient, wherein the active ingredient content is preferably from 3 to 10%. Anti-foaming agent against water parasites is described in DD-PS 82 379. Here, the active substance used is at least one alkyldithiocarbamate or alkylenebis dithiocarbamate of copper or of copper and one of the metals zinc, manganese, iron, cadmium or nickel. Also in DD-PS 117691 a material for preventing growth on underwater outer surfaces is protected, consisting of a material combined with at least one anti-fouling material, which material is combined with a chlorine and / or bromine and / or iodine releasing compound.

The solutions known from the prior art have the disadvantage that in the case of the paint and lacquer coatings as well as the untreated surfaces on watercraft of all kinds, they do not provide a pore-free surface. The subsequently applied antifouling wax- and paraffin-containing protective layers are products in which the antifouling properties are based on the toxic effect of certain components and are therefore harmful to the environment.

Object of the invention

It is an object of the invention to find an anti-fouling care, mii the protection, care, preservation and cleaning of underwater outer surfaces is made possible on watercraft. In addition to these protective, care and preservation functions, the amount of possible cleaning work on the treated surfaces should be reduced and facilitated. Furthermore, in the interest of active water protection, the use of products with toxic active substances should be avoided.

Explanation of the essence of the invention

The invention has for its object to develop a anti-fouling care product for the protection, care, preservation and improvement of the cleaning of underwater external surfaces of watercraft. According to the invention, the object is achieved by a mixture consisting of 1.0 to 4.0 parts by mass in% hard wax according to TGL 23154 of 1.5.1987 and white standard M 31 578 of the VEB HydrierwerkZeitz from 1.1.1978, 1, to 5, % By weight of montan wax raffinate average hard wax content according to TGL 23294 of 1.8.1986 and according to works standard M 31 579 of the VEB hydrogenation plant Zeitz from 1.1.1988.1.0 to 3.0 parts by weight in% mixed oil fatty acids as a mixture unbranched saturated straight-chain monocarboxylic acids having a chain length of C _{) 2} to C ₂₂ , 0.5 to 2.0 parts by mass in% alkali oxides or hydroxides or carbonates or hydrogencarbonates or alkaline earth oxides or hydroxides or carbonates or bicarbonate, 1.0 to 5.0 parts by mass in% silicone oil according to TGL 8467/1 of the VEB Chemische Werke Nünchritz from 1.1.1978, 32.0 to 42.0 parts by weight in% petroleum hydrocarbons of the boiling point 100 to 200 ⁰ C, 0, 5 to 2.5 parts by mass in% of a mixture of solid high molecular weight, mainly aliphatic, hydrocarbon open the chain length C _ig to (\ ₈ , 0.5 to 1.5 parts by weight in% of a nonionic emulsifier as a combination of lower and higher oxyethylated Alkylphenylpolyglykolether, 0.5 to 5.0 parts by weight in% spruce extract resin Plant standard M 31 565 of the VEB hydrogenation plant Zeitz from 26.3.1981 or pine extract resin to works standard M 31 566 of the VEB hydrogenation plant Zeitz from 26.3.1981 or rosin to TGL 33059 from 1.6.1980 or Tallharz to factory standard with quality standard WSQ 0311/39361 -02 from 1.3 .1986 of the VEB Wittenberge pulp and wool factory, individually or mixed, and 40.0 to 52.0 parts by mass dissolved in% demineralized water. The products included in the standard M 31578, M 31579, M 31 B65 and M 31566 are commercial products of the VEB hydrogenation plant Zeitz, while the products included in the standard WSQ 0311/39361 -02 are commercial products of VES Zellstoff- und Zellwollewerk Wittenberge.

The care product according to the invention can be used both for watercraft made of sheet steel, the multi-layer applied paint and paint coatings for protection against corrosion, as well as made of wood craft, which are protected against decay either dyeing and coating or with bitumen or tar coatings used become. Particularly suitable is the care product for the treatment of watercraft plastic against unwanted algae and microorganisms.

It was surprisingly found that the treated with care agents underwater outer surfaces of watercraft are not occupied or infested by algae and water organisms. The application and subsequent polishing of the care agent film eliminates the micropore volume and surface roughness of the material.

Furthermore, it was found that in addition to the protection, care and preservation function also a significant simplification and ease in the cleaning of the underwater outer surfaces is achieved without the use of mechanically acting cleaning aids such as scrapers, scratches or sandpaper is necessary.
