Description

Description of the invention

The subject of the invention is a microbiologically active and insect repellent water dispersion paint for painting houses for farm animals, especially for painting houses for poultry.

Active microbiological water dispersion paints containing agents against the growth of bacteria and fungi, based on water dispersions of copolymers obtained from acrylic monomers and styrene, for painting concrete surfaces, cement-lime plasters, drywall, etc. are known and used.

From the description of the application for the invention P.407981, a paint is known, the coating of which is resistant to the action of microorganisms as a result of the addition of appropriate biocides and fungicides.

They are known from EP 0616015 and WO 9426826 whose coatings are resistant to the action of microorganisms due to the addition of suitable biocides and fungicides.

A paint with a coating against the action of microorganisms is known from the European patent description EP 0682091. The composition is intended to protect the surface of building materials against the action of microorganisms, fungi and algae.

The publication of the invention is known from the international application WO 9703135, an aqueous acrylic dispersion paint that significantly reduces the growth of bacteria in time. The publication describes a dispersion paint with increased microbiological resistance.

It is known from the patent description PL 203423 a dispersion paint with increased microbiological resistance, containing pigments and fillers, wetting and dispersing agents, coalescing and biocides, as well as acrylic and acrylic-styrene binders, rheology modifiers, as well as biocides in the form of carbendazim, diuron and octylisothiazolone, which protects the coatings against the action of microorganisms.

These compositions are water-based dispersion paints that protect the coating against the growth of microorganisms, while also maintaining a decorative appearance. The main disadvantage of commonly used dispersion paints with microbiological protection for the construction industry for decorative painting of internal and external walls is only the protection of coatings against the action of algae, fungi and bacteria.

It turns out that the intestinal bacteria Salmonella, which cause large losses in poultry farms, are a big problem in breeding rooms, especially for poultry.

It also turns out that some sectors of the construction industry require additional and more effective protection, protection against insects such as flies and spiders, but also against insects inhabiting breeding houses for poultry, such as black mites and mites, by using a second optical repellent.

As a result of the research, a microbiologically active water dispersion paint with extended protection against fungi and bacteria, especially against intestinal bacteria, Salmonelle, was developed, which also repels insects and is not harmful to farm animals and humans.

The essence of the invention is a microbiologically active and insect repellent water dispersion paint containing pigments, fillers, cellulose ethers, antifoams and dispersants, aqueous copolymer dispersions, biocides and repellants, as an anti-fungal and bacterial agent it contains zinc pyrithione in an amount of 0.08-0 12% by weight as insect repellants contain permethrin (3-phenoxybenzyl 3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropanecarboxylate) in an amount of 0.04 to 0.08% by weight or thiamethoxam in an amount of 2.00 to 4.00 wt.% Or DEET - (N, N-diethyl-M-toluamide) in an amount of 1.00 to 3.00 wt.%, Characterized in that it additionally comprises 1,2-benzisothiazole as an anti-fungal and anti-bacterial agent. 3 (2H) -one in an amount of 0.03 to 0.05% by weight and amines coco acrylic, ethoxylated 1-4.5 moles ethoxylated in an amount of 0.015 to 0.025% by weight, potassium hydroxide in an amount of 0.012 to 0.021% by weight, zinc oxide in an amount of 0.007 to 0.014 wt% and octhilinone in an amount of 0.003 to 004 wt% Ag compounds and titanium dioxide in an amount of 0.001 to 0.0025% by weight and, as insect repellants, additionally comprises a mixture of ultramarine and pigment violet 23 in a ratio of 0.3: 1 in an amount of 0.0002-0.0004% by weight.

The coatings obtained from the aqueous dispersion paint according to the invention show an activity against fungi and bacteria, and in particular against the intestinal Salmonella bacteria, preventing the formation of spores and their development.

PL 232 978 B1

Moreover, thanks to the use of two repellants (chemical - permethrin and optical - ultramarine with violet 23), it was surprisingly found that this combination of the indicated ingredients used in the paint according to the invention causes insect repellency in animal housing such as stables, pigsties, barns, sheepfolds and especially poultry houses. The coating, after being painted, provides full microbiological protection, protects the surface of farm animals against bacteria and fungi and provides protection against insects.

The subject of the invention is presented in more detail in the examples of the implementation.
