Definitions

  • the present invention relates to a method for manufacturing paint or varnish
  • nanoparticles improve the properties of products, for instance paints and varnishes.
  • dispersing of nanoparticles into varnish or paint has been problematic, it has not been possible to fully exploit the advantages which nanoparticles have offered to coatings.
  • nanoparticles When nanoparticles are added into a coating, they must be mixed into it in such a way that they do not form aggregates. Furthermore, they should remain as separate particles even during the coating process and the settling (drying) of the coating.
  • Nanoparticles are added into coatings in order to improve e.g. resistance to wear and to scratching, as well as as a UV shield (to protect a varnish surface and/or a coated product). In most cases, inorganic nanoparticles are used. To allow the nanoparticles to function as desired, they must often be added in relatively large amounts into the coating
  • NFC nanofibrillated cellulose
  • the nanoparticles are first mixed into the nanocellulose. (It is possible to carry out the addition by means of e.g. mechanical, ultrasound-assisted or another suitable mixing.) This mixture is added into the paint or varnish composition.
  • This mixture is added into the paint or varnish composition.
  • the result is a coating in which the particles and/or nanoparticles are evenly distributed throughout the matrix already with small amounts of nanocellulose: even as only 0.1 % of the amount of the dry matter of the binder/coating.
  • good results have been achieved with amounts of nanocellulose of 0.5-5 % of the dry matter of the coating, and it is possible to achieve a good result even with a mixture portion of only 0.1 percent.
  • the result is a composition in which the particles and/or nanoparticles are evenly distributed throughout the matrix at small nanocellulose amounts: the amount varying between 0.2 and 2.0 % of the amount of the binder.
  • One preferred way of manufacturing the composition is to first mix the particles and/or the nanoparticles into an aqueous cellulose gel which is at least partly fibrillated into nanofibrils, which aqueous gel is then added into the paint or varnish composition. Due to this nanofibrillated cellulose carrier, the particles remain evenly distributed throughout the composition of the paint/varnish etc. for a sufficient period of time for the coating process.
  • the nanoparticles remain mixed in the matrix of varnish or paint, and no aggregates are formed during or after the mixing. Over time, the nanoparticles may separate from the mixture, but light shaking evenly redistributes them again throughout the composition of paint or varnish. Thus, it is unnecessary for the nanoparticles to be permanently adhered to the nanocellulose, which is a substantial advantage. Small amounts of NFC are not detrimental to the viscosity of the coating composition.
  • the application potential is wide for wood and metal coatings, plastics and textiles, intended for use both outdoors and indoors. The wear and scratch resistance of the coatings are important properties, among others, in wooden floors, electrical displays and coatings of the automotive industry, and in many other consumer products. Inorganic UV shields are used, among others, in suntan lotions and varnishes.

Abstract

L'invention consiste à produire de nouvelles propriétés dans des revêtements à l'aide de différentes nanoparticules. A l'aide des nanoparticules, il est possible d'améliorer la résistance de produits à l'usure et à la rayure, la résistance aux UV, la conductivité et d'autres propriétés. Cependant, il est difficile de distribuer uniformément les nanoparticules dans la composition de peinture ou de vernis et, en conséquence, les propriétés souhaitées ne sont pas toujours réalisées, ou les nanoparticules doivent être ajoutées en quantités telles qu'elles ne sont pas économiquement rentables pour réaliser les propriétés souhaitées. Dans la présente invention, les nanoparticules sont d'abord ajoutées par mélange mécanique dans un gel de cellulose, qui est partiellement fibrillé en nanofibrilles, lequel gel aqueux est ensuite ajouté à la composition de peinture ou de vernis. Du fait de ce support en cellulose nanofibrillé, les particules restent uniformément distribuées partout dans les matériaux de revêtement et autres matériaux similaires, tels que le liant de la peinture ou du vernis, pendant une durée suffisante pour le processus de revêtement.
