Research on the Influence of Wood Nitrocellulose Coatings Modified by Nano-TiO₂

Abstract:

Using nano TiO₂ nitro coating was modified, and the mechanical properties of modified wood nitro coating (wear resistance, hardness, adhesion and impact resistance performance) and optical properties of tested effects of nano TiO₂ film mechanical properties and optical properties of the inquiry. The results show that: the nanometer TiO₂ addition of different had not significant effects on the hardness and adhesion of the film, add the amount to 0.1g, the film with better wear resistance and impose on Matt state. At this time of nano TiO₂ with the coating quality than when 1.30am, further use 0.01g alkyl ketene dimer of 0.1g nano TiO₂ after surface modification and coating performance obtained at best. At this time film hardness Hb. The adhesion was grade 1 and the wear value for 0.024g and gloss was 19%. The study enriched the inorganic nanoparticles (TiO₂) change the scope of application of the nitro paint.
