DISPERSION PAINT FOR MARKING GRASSY SURFACES

The presented innovation describes an environment-friendly dispersion painting agent on the water basis for designation, marking or colouring of grassy surfaces. The subject of patent claims are the composition of the paint and the low content of hazardous substances. The dispersion formulation contains selected polymer and copolymer dispersions, calcite, silicate and pigment fillers as basic components, while selected low-content additives such as a wetting agent, a dispersant and a defoamer impart required properties to the paint. The characteristics of the dry layer of the paint mixture are good adhesion and abrasion resistance. Further characteristics of the mixture are low content of hazardous organic volatile matter, heavy metals and other substances that might negatively influence the growth of grass sod, or endanger health protection at work and environment in general. The base for the application of the paint can be any mowed and racked, dry and clean grass-seeded surface. The basic colour of the paint is white and can be shaded by addition of pigments or pigment pastes. The colour is applied in one or two layers by spraying, on smaller surfaces also with a long-hair paint roller or paint brush. Predstavljena inovacija opisuje okolju prijazno, disperzno premazno sredstvo na vodni osnovi za označevanje, markiranje ali barvanje travnatih površin. Predmet patentnih zahtevkov je sestava premaza in nizka vsebnost nevarnih snovi. Formulacija disperzije vsebuje izbrane disperzije polimerov in kopolimerov, kalcitna in silikatna ter pigmentna polnila kot osnovne komponente, a nizka vsebnost izbranih dodatkov: omakalo, dispergator in protipenilec premazu omogočajo zahtevane lastnosti. Značilnost suhegasloja premazne zmesi je dobra oprijemljivost in odpornost na drgnjenje. Za zmes je značilna nizka vsebnost nevarnih organskih, hlapnih snovi in težkih kovin ter drugih snovi, ki bi lahko negativno vplivale na rast travne ruše, oziroma na splošno na varovanje zdravja pri delu in okolje. Podlaga za aplikacijo premaza je lahko vsaka pokošena in pograbljena, suha in čista zatravljena površina. Osnovna barva premaza je bela, ki se niansira z dodatkom pigmentov, oziroma pigmentnih past. Barva se nanaša v enemali dveh slojih z brizganjem, na manjše površine tudi z dolgodlakim pleskarskim valjčkom ali s pleskarskim čopičem.
