Abstract

With different nanoparticles, new properties are generated in coatings. Using the nanoparticles, it is possible to improve the resistance of products to wear and scratching, the UV resistance, the conductivity and other properties. However, it is difficult to evenly distribute the nanoparticles in the composition of paint or varnish, and, as a result, the desired properties are not always achieved, or the nanoparticles must be added in amounts that are economically unprofitable to achieve the desired properties. In the present invention, the nanoparticles are first added by mechanical mixing into a cellulose gel, which is fibrillated partly into nanofibrils, which aqueous gel is then added into the composition of paint or varnish. Due to this nanofibrillated cellulose carrier, the particles remain evenly distributed throughout the coating materials and other similar materials, such as the binder of the paint or varnish, for a sufficient period of time for the coating process.

Description

Menetelmä maalin tai lakan valmistamiseksiProcess for preparing paint or varnish

Keksinnön kohteena on patenttivaatimuksen 1 johdanto-osan 5 mukainen menetelmä maalin tai lakan valmistamiseksi.The invention relates to a process for the production of paint or varnish according to the preamble of claim 1.

Nanopartikkelit parantavat tunnetusti tuotteiden, kuten myös maalien ja lakkojen ominaisuuksia. Nanopartikkeleiden tuomia etuja pinnoitteissa ei ole pystytty täysimääräisesti 10 hyödyntämään tapauksissa, joissa nanopartikkeleiden dispergointi lakkaan tai maaliin on tuottanut ongelmia. Kun nanopartikkeleita lisätään pinnoitteeseen, pitää niiden sekoittua siihen niin, etteivät ne muodosta aggregaatteja. Lisäksi niiden tulee säilyä erillisinä partikkeleina vielä 15 pinnoitusprosessin ja pinnoitteen asettumisen (kuivumisen) aikana.Nanoparticles are known to improve the properties of products as well as paints and varnishes. The benefits of nanoparticles in coatings have not been fully utilized 10 in cases where the dispersion of nanoparticles in lacquer or paint has caused problems. When nanoparticles are added to the coating, they must be mixed so that they do not form aggregates. In addition, they must remain separate particles for a further 15 coating processes and coating deposition (drying).

Nanopartikkeleita lisätään pinnoitteisiin esim. kulutus- ja naarmuuntumiskestävyyden parantamiseksi sekä UV-suojaksi 20 (lakkapinnan ja/tai pinnoitetun tuotteen suojaksi). Useimmiten käytetään epäorgaanisia nanopartikkeleita. Toimiakseen odotetulla tavalla nanopartikkeleita joudutaan usein lisäämään pinnoitteen (maali/lakka) sekaan suhteellisen suuria määriä. Tällöin kasvaa riski, että ne aggregoituvat tai erottuvat 25 painuen pinnoitteen pohjaan eikä haluttua tehokkuutta „ saavuteta.Nanoparticles are added to coatings, for example to improve wear and scratch resistance, and to provide UV protection 20 (to protect the lacquer surface and / or coated product). Inorganic nanoparticles are most often used. In order to function as expected, relatively large amounts of nanoparticles are often added to the coating (paint / varnish). This increases the risk that they aggregate or separate, sinking to the bottom of the coating and not achieving the desired performance.

35 Keksinnössä on käytetty nanofibrilloitua selluloosaa (NFC) maalin tai lakan partikkeleiden ja/tai nanopartikkeleiden kantaj a-aineena.The invention utilizes nanofibrillated cellulose (NFC) as a carrier for paint or varnish particles and / or nanoparticles.

Keksinnön mukaisessa menetelmässä nanopartikkelit sekoitetaan ensin nanoselluloosan joukkoon. (Lisääminen voidaan suorittaa esim. mekaanisella, ultraääniavusteisella tai muulla sopivalla 5 sekoituksella.) Tämä seos lisätään maalin tai lakan koostumukseen. Tuloksena saadaan pinnoite, jossa partikkelit ja/tai nanopartikkelit ovat tasaisesti jakaantuneet matriisiin jo pienillä nanoselluloosan määrillä: jopa vain 0,1% sideaineen/pinnoitteen kuiva-aineen määrästä. Testeissä on 10 saavutettu hyviä tuloksia nanoselluloosan määrillä 0,5 - 5 % pinnoitteen kuiva-ainepitoisuudesta ja hyvään tulokseen on mahdollista päästä jo 0,1 prosentin seososuudella. Kokeita on tehty myös siten, että tuloksena on saatu koostumus, jossa partikkelit ja/tai nanopartikkelit ovat tasaisesti 15 jakaantuneet matriisiin pienillä nanoselluloosan määrillä: määrän vaihdellessa 0,2 - 2,0% sideaineen määrästä.In the process of the invention, the nanoparticles are first blended with nanocellulose. (Addition may be effected, for example, by mechanical, ultrasonic or other suitable mixing.) This mixture is added to the composition of the paint or varnish. The result is a coating in which the particles and / or nanoparticles are evenly distributed in the matrix with small amounts of nanocellulose: up to only 0.1% of the binder / coating dry matter. Tests have shown good results with nanocellulose contents of 0.5 to 5% of the dry solids content of the coating and a good result can be achieved with a 0.1% blend. Tests have also been carried out to obtain a composition in which particles and / or nanoparticles are uniformly distributed in the matrix with small amounts of nanocellulose: in an amount ranging from 0.2 to 2.0% of the amount of binder.

Eräs edullinen tapa koostumuksen valmistamiseksi on, että partikkelit ja/tai nanopartikkelit sekoitetaan ensin vähintään 20 osittain nanofibrilleiksi saakka fibrilloituun vesipohjaiseen selluloosageeliin, joka sitten lisätään maalin tai lakan koostumukseen. Tämän nanofibrilloidun selluloosakantaja-aineen ansiosta partikkelit pysyvät pinnoitusprosessiin riittävän ajan tasaisesti jakaantuneena maalin/lakan yms.One preferred way of preparing the composition is to first mix the particles and / or nanoparticles into at least 20 partially nanofibrilic water-based cellulose gels, which are then added to the paint or varnish composition. Thanks to this nanofibrillated cellulose carrier material, the particles remain uniformly distributed throughout the coating process over a sufficient period of time over the paint / varnish and the like.

Kulutuskestävyys paranee NFC:n määrän kasvaessa. Lisäksi on huomoitava erilaiset levitysmäärät. Kaikkiin on levitetty sama 5 määrä 150 g/m2 märkää lakkaa + nanopartikkeleita (0-näyte) tai lakkaa + nanopartikkeleita+ NFC . Kun todellisuudessa otetaan huomioon kuiva-aine, niin NFC-näytteissä on levitysmäärä huomattavasti pienempi kuin pelkässä lakka + nanopartikkelinäytteessä ja silti kulutuskestävyys paranee.The abrasion resistance improves as the amount of NFC increases. In addition, different application rates must be noted. The same 5 amount of 150 g / m 2 wet lacquer + nanoparticles (0 sample) or lacquer + nanoparticles + NFC have been applied. When the dry matter is actually taken into account, the application rate of NFC samples is significantly lower than that of the lacquer + nanoparticle sample alone and yet the wear resistance is improved.

Keksinnön mukaisen menetelmän etuina on mm. se, että nanopartikkelit säilyvät sekoittuneena lakka- tai maalimatriisissa eikä aggregaatteja muodostu sekoituksen aikana tai sen jälkeen. Ajan kuluessa nanopartikkelit 15 saattavat erottua seoksesta, mutta kevyesti ravistamalla ne saadaan jälleen tasaisesti maali- tai lakkakoostumuksen sekaan. Siten nanopartikkelien pysyvä sitoutuminen nanoselluloosaan ei ole välttämätöntä, mikä on huomattava etu. Pienet NFC-määrät eivät vaikuta pinnoitekoostumuksen 20 viskositeettiin haitallisesti.Advantages of the method according to the invention are e.g. the fact that the nanoparticles remain mixed in the lacquer or paint matrix and that no aggregates are formed during or after mixing. Over time, the nanoparticles may separate from the mixture, but by gentle agitation, they are again uniformly mixed with the paint or varnish composition. Thus, permanent binding of nanoparticles to nanocellulose is not necessary, which is a considerable advantage. Small amounts of NFC do not adversely affect the viscosity of the coating composition.
