Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania bakteriostatycznych wyrobów higienicznych, zwłaszcza papierowych ręczników dwuwarstwowych, który polega na sklejaniu za pomocą wodorozcieńczalnego kleju syntetycznego w postaci roztworu alkoholu poliwinylowego. Do kleju dodaje się nanocząstki srebra w postaci wodnej dyspersji nanocząstek srebra w zakresie od 3 do 25 nm, pH w zakresie 5 - 7,4 i o stężeniu nanocząstek srebra od 0,001 do 0,007g/dm3 w wodzie destylowanej lub demineralizowanej, uzyskanej przez ciągłe mieszanie trwające od 0,5 h do 1 h, przy prędkości mieszania w zakresie od 200 do 900 obr/min. Klej i wodę z nanocząstkami srebra rozcieńcza się w proporcjach 1 część kleju i 3 części wody, przy prędkości mieszania od 500 do 1000 obr/min przez około godzinę w temperaturze od 15 do 36°C. Tak sporządzony klej nanosi się i rozprowadza po bibułce za pomocą wałków pokrytych korzystnie teflonem.The subject of the application is a method for producing bacteriostatic hygiene products, especially two-layer paper towels, which involves gluing with a water-borne synthetic adhesive in the form of a polyvinyl alcohol solution. Silver nanoparticles are added to the adhesive in the form of an aqueous dispersion of silver nanoparticles in the range from 3 to 25 nm, a pH in the range 5 - 7.4 and with a concentration of silver nanoparticles from 0.001 to 0.007g / dm3 in distilled or demineralized water, obtained by continuous mixing from 0.5 h to 1 h, at a mixing speed in the range from 200 to 900 rpm. The glue and water with silver nanoparticles are diluted in a proportion of 1 part glue and 3 parts water, at a mixing speed of 500 to 1000 rpm for about an hour at a temperature of 15 to 36 ° C. The adhesive prepared in this way is applied and spread on the paper using rolls preferably coated with Teflon.
