Problems solved by technology

The disadvantage of this case is that the metal ions may be transformed into their oxides, hydroxides or other salts during the ion exchange process, and they deposit in this form on the surface of the laminate, thus impairing the antimicrobial activity there
Another disadvantage from a health point of view is related to the use of heavy metals in these zeolites

Embodiment 1

[0061] Preparation of Antibacterial Melamine Formaldehyde Resin

[0062] 500 g of melamine / formaldehyde resin (Agrolinz Melamin Italia) were dissolved in 500 g of water, then 3 g of wetting agent Melpan NU02MF and 5 g of curing agent Melpan A462 (common wetting and release agent from Agrolinz Melamin Italia) were added. The precondensed mixture of aqueous amino resin was stirred until a clear solution was obtained.

[0063] Then mix into the melamine resin solution

[0064] - in the case of sample D, 10 g of industrial zinc borate are mixed, and

[0065] - In the case of sample E, 2.5 g technical zinc borate, 2.5 g technical sodium borate and 1.25 g benzalkonium chloride were mixed

[0066] The solution after addition was stirred for 10 minutes until a homogeneous suspension was formed.

[0067] Production of Antimicrobial Laminates

[0068] The antibacterial melamine resin suspension is used for white decorative paper (density: 80g / m 2) for impregnation. Subsequently, t...

Abstract

The invention relates to an anti-bacterial additive for melamine resins, in particular for melamine-formaldehyde or melamine-urea-formaldehyde resins. Said additive is characterised in that it comprises at least one borate salt and a quaternary ammonium compound as the anti-bacterial active ingredients. As a result of the small number of individual constituents, said additive can be easily incorporated into the melamine resin, is extremely compatible with the latter and has an effective, long-lasting anti-bacterial action.

Description

technical field [0001] The present invention relates to an antibacterial additive for melamine resin of claim 1, to the antibacterial melamine resin of claim 16, to the method for preparing the melamine resin of claim 17, to the antibacterial laminate of claim 21, to the antibacterial melamine resin of claim 22 Process for the preparation of an antimicrobial laminate, and use of the antimicrobial laminate according to claim 24. Background technique [0002] Melamine resins are used in various industrial applications, for example for surface coatings, or otherwise in the production of decorative laminates. The most industrially important of the melamine resins are the melamine-formaldehyde resins and the melamine / urea-formaldehyde resins. Due to their outstanding properties such as scratch resistance, flame retardancy, chemical and mechanical stability and hardness, they are ideally suited for articles under high stress, especially for surfaces in everyday use. Melamine res...
