New formulations of coatings by means of the utilisation of nanoaditivos

The project has developed along two years and his aim has been to study pormenorizadamente the effects of the addition of nanocompuestos to glaze them and coatings more employed of the sector of the piece of furniture and the habitat, with the object to confer them high mechanical provision, improving the quality of the product and expanding the current uses of the products recubiertos.

During his development have tackled four big phases of performance: 1) Compilation and research of relative information to the nanoaditivos with properties of mechanical resistance, analysing his characteristics and potentialities. 2) Determination and study of the nanopartículas purchased. 3) Formulation, application and characterisation of glaze them and coatings in dust aditivados with the nanopartículas purchased that better characteristic present. And 4) Optimisation of the formulations realised.

- Have prepared coatings reticulables by means of radiation UV that incorporate particles to scale nanométrica that they have improved the resistance to the abrasion, to the rayado and to the impact without modifying the aesthetic properties of original coatings. It has studied the effect of the incorporation of materials nanométricos of different nature in the mechanical properties of the coatings applied on ceramic pieces. Said coatings can be applied so much on ceramic materials, glass, wood, or other materials of construction.

- Have prepared sustratos of marble with hybrid coatings sun-gel that produce a high provision so much of resistances to the rayado as in mechanical resistances to flexión. Although it loses something of shine because of the rugosidad that generates by the training of nanopartículas of silica, what could give place to a future investigation on his applicability like pavimento antideslizante. On the other hand, the nanopartículas studied do not modify the texture of the coatings giving improvements in the properties of hardness and adhesion.

- Have formulated and applied to sustratos metallic, paintings in dust aditivadas with nanopartículas that have modified his mechanical properties, conferring them a different mechanical resistance to the initial, being evident, the parallelism found between the proofs macro and microscopic. The changes in the texture and the colour by the addition of some nanopartículas were notorious, fact that poses the need to tackle new works that allow to know the implicit chemical mechanism responsible of the changes of texture and colour obtained when adding the nanopartículas in the paintings in dust.
