Definitions
- the invention relates to a biocidal coating material and an associated production method.
- Coatings based on epoxides are widely used. These are based essentially on bisphenol A diglycidyl ether, bisphenol F diglycidyl ether, bisphenol diglycidyl ether, novolak epoxy systems and various amines as Hartem, z. Diethylenetriamine, dipropylenetriamine, isophoronediamine, 2,2,4- / 2,4,4-trimethylhexanediamine, etc.
- a biocidal effect, i. H. the prevention of the formation of biofilms on the surface of the coating and the subsequent growth of bacteria, algae, microfungi or marine organisms is usually achieved by additives.
- Such additives may include metals such as copper, tin or silver in various forms, organic chloro and sulfur compounds such as carbendazim or 2-methylthio-4-ferf-butylamino-6-cyclopropylamino-s-triazine, propioconazole, 3- (3,4 Dichlorophenyl) -1, 1-dimethylurea (diuron), 2-octylisothiazol-3 (2H) on (octhilinone), or metal compounds such as bis (tributyltin) oxide, triphenyltin hydroxide, and triphenyltin chloride.
- the active principle of all these compounds is based on the fact that small amounts are continuously released into the environment, but there can not be degraded due to their properties and accumulate.
- WO 2014/008264 A1 describes antimicrobial compositions based on polyhaloolefin polymers and cationic antimicrobial reagents as well as a carrier with plasticizer and heat stabilizer, wherein the antimicrobial compound is incorporated into the polymer structure.
- oligourea compounds are dispersed in glycols and / or polyether alcohols.
- Polyurethane urea coatings based on this have inherently biocidal activity. These oligourea compounds are due to the content of diols / polyols as hardener components for epoxy resins less or not suitable, especially in coatings in which the leaching of ingredients of the coating is to be avoided in contact with water.
- the method comprises the steps:
- a ratio of the sum of the primary and secondary amine groups to the isocyanate groups is 10: 1 to 2: 1;
- a ratio of the epoxy groups of the epoxy component to the amine groups of the urea amine component is 0.25: 1 to 1: 0.25, preferably 0.5: 1 to 1: 0.5.
- the oligoureaamines obtainable by the process according to the invention based on mixtures of monoamines and di- and / or polyamines which have been partially reacted with one or more di- or triisocyanates can form layers or films in their further reaction with epoxide compounds which have inherent biocidal activity. These layers or films also have high water, oxygen and / or carbon dioxide blocking capability.
- step (i) of the process an oligourea composite is first formed by an addition reaction of isocyanates and various amines. The latter is then reacted in step (iii) with polyfunctional glycidyl ethers to form a novel, crosslinked coating material.
- step (i) used by amines, which differ by the number of existing primary or secondary amine groups.
- a first amine has only a single primary or secondary amine group, while the second amine has 2 or more of these functionalities and may optionally include a tertiary amino group.
- Subsequent reaction with polyfunctional isocyanates produces a complex mixture of oligoureas still having free amine groups and one or more amines.
- the first amine is preferably a C 3 -C 15 -cycloamine or a compound of the formula (1)
- R 1 selected from the group consisting of C 1 -C 15 alkyl, C 3 -C 10 cycloalkyl and C 3 -C 10 heterocycloalkyl and
- R 2 selected from the group comprising hydrogen, C 1 -C 15 alkyl, C 3 -C 10 cycloalkyl and C 3 -C 10 heterocycloalkyl.
- the second amine is preferably a C 3 -C 15 -cycloamine or a compound of the formula (2)
- R 1 selected from the group consisting of C 1 -C 15 alkyl, C 3 -C 10 cycloalkyl and C 3 -C 10 heterocycloalkyl and
- R 2 and R 3 are independently selected from the group comprising hydrogen, C1 - C15 alkyl, C3-C10 cycloalkyl, and C 3 -C 0 heterocycloalkyl.
- the two amine groups (-NH 2 ) a and (-NH 2 ) b are bonded to the radical R 1 directly or via alkylene, in particular methylene bridges.
- the alkyl groups of the diamines may also be linked by an optionally substituted amino group, such as in bis-N, N- (3-aminopropyl) -N-methylamine.
- an aliphatic di- or triisocyanate is meant an acyclic or cyclic, saturated or unsaturated carbon compound having two or three isocyanate groups. Preference is given to diisocyanates of the formula (3)

- the two isocyanate groups (-NCO) a and (-NCO) b are bonded directly to the radical R 1 .
- araliphatic di- or triisocyanate is understood as meaning a carbon compound in which the two or three isocyanate groups are bonded directly to one or more aliphatic side chains of an aryl group. Preference is given to araliphatic diisocyanates of the formula (4)
- the isocyanate components may be prepolymers (prepolymers or quasi-prepolymers) of di- and / or triols and diisocyanates, diamines and diisocyanates, or triisocyanates obtained by symmetrical or asymmetric trimerization of aliphatic and / or cycloaliphatic diisocyanates.

- the ratio of the isocyanate groups to the hydroxyl groups is preferably between 2.1: 1 and 5: 1, in particular between 2.1: 1 and 2.8: 1.
- prepolymers are formed from a diol and a diisocyanate in a ratio of 2.1: 1 to 3.5: 1 and added immediately after their preparation in a mixture of mono- and diamines and split therein again with urea formation and release of the diol
- Suitable diols for this variant of the method according to the invention are, for.
