Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : Nowadays smart polymers, smart materials, smart coatings are getting a lot of attention in the research field. Amongst them smart coatings are the fastest developing and the most interesting technology. Smart coatings are called as "SMART'? because they respond to environmental changes in a predictable and noticeable manner. The technology discussed in this paper is "Superhydrophobic coating". This effect, was originally observed in the nature (e.g. on lotus leaves), and is important fora wide range of scientific and technological applications, like developing coatings that possess self-cleaning properties, prevention of surface fouling and anti-corrosion. Superhydrophobic surfaces are those whose water contact angle is greaterthan 150° and have low surface energy. Water droplets do not slide, but roll down the superhydrophobic surface, carrying dust along with it and thereby cleaning the surface. The corrosion protection mechanism is related, first, to the reduction of the electrolyte—metal contact area, and second, to the reduction of the corrosion current. Such coatings are also used to reduce leakage currents on the surface of silicon insulators .This paperfocuses on superhydrophobic coatings based on silicone resins, fluoro-organiccompounds and nanomaterials.

ViscositéIndex. décimale : 667.9 Revêtements et enduits Résumé : Hydrophobically modified ethylene oxide urethanes or 'HEUR' rheology modifiers provide rheology profiles offering excellent flow and levelling, good water resistance properties and efficient ways to increase the high shear application viscosity. An enhanced technology has been developed in HEUR chemistry to offer ways to produce concentrated HEUR rheology modifiers without the need for organic solvent or additives, like surfactants, to suppress the solution viscosity. This allows one to produce HEURs with low 'as supplied' viscosity for ease of handling in production.
In addition, this technology offers materials that contribute to narrow the gap in several performance areas including increased thickening efficiency and cost in use, improved balance between levelling and sag, improve applied hide and reduced viscosity loss upon tinting.Note de contenu : - HEUR acid suppression technology

Titre : A new route for fabrication of the corrosion-resistant superhydrophobic surface by milling process Type de document : texte imprimé Auteurs : Zhu Jiyuan, Auteur ; Xiaofang Hu, Auteur Année de publication : 2019 Article en page(s) : p. 249-255 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Aluminium L'aluminium est un élément chimique, de symbole Al et de numéro atomique 13. C’est un métal pauvre, malléable, de couleur argent, qui est remarquable pour sa résistance à l’oxydation13 et sa faible densité. C'est le métal le plus abondant de l'écorce terrestre et le troisième élément le plus abondant après l'oxygène et le silicium ; il représente en moyenne 8 % de la masse des matériaux de la surface solide de notre planète. L'aluminium est trop réactif pour exister à l'état natif dans le milieu naturel : on le trouve au contraire sous forme combinée dans plus de 270 minéraux différents, son minerai principal étant la bauxite, où il est présent sous forme d’oxyde hydraté dont on extrait l’alumine. Il peut aussi être extrait de la néphéline, de la leucite, de la sillimanite, de l'andalousite et de la muscovite.
L'aluminium métallique est très oxydable, mais est immédiatement passivé par une fine couche d'alumine Al2O3 imperméable de quelques micromètres d'épaisseur qui protège la masse métallique de la corrosion. On parle de protection cinétique, par opposition à une protection thermodynamique, car l’aluminium reste en tout état de cause très sensible à l'oxydation. Cette résistance à la corrosion et sa remarquable légèreté en ont fait un matériau très utilisé industriellement.
L'aluminium est un produit industriel important, sous forme pure ou alliée, notamment dans l'aéronautique, les transports et la construction. Sa nature réactive en fait également un catalyseur et un additif dans l'industrie chimique ; il est ainsi utilisé pour accroître la puissance explosive du nitrate d'ammonium.

Traîtements de surfaceIndex. décimale : 667.9 Revêtements et enduits Résumé : Mechanical processing is promising for the preparation of superhydrophobic surfaces. But the practical application is often restricted by the cost for precision instruments or the use of sophisticated technology. A novel mechanical route is reported to prepare superhydrophobic surfaces on aluminum alloys via the milling process using self-made disk cutters. Uniform groove-like microstructures were formed on the aluminum alloy surfaces, and after modifying with stearic acid solution, the surfaces became superhydrophobic. The surface morphologies, chemical compositions, and wettability of the obtained superhydrophobic surfaces were studied. Potentiodynamic polarization curves revealed that the superhydrophobic surfaces obtained good anticorrosion resistance. A formation mechanism for the surface morphologies was also proposed. This method is significant for the industrial applications of superhydrophobic surfaces due to its low cost, simple process, and great efficiency.

Stabilité thermiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : In this paper, a series of acrylate-polydimethylsiloxane (PDMS) composite latexes was prepared and studied systematically to find the factors that affect their performances. At first, the modified PDMS was synthesized to react with acrylate monomers and participate in free radical polymerization. Then, the modified PDMS was blended with acrylate monomers, and the acrylate-PDMS composite latexes with different formulas were obtained by emulsion polymerization. Because the blending monomers were constrained in the micelle, the two components were interconnected with each other by a covalent bond and the phase compatibility between the two components could be controlled well. Chemical constitution and the morphology of acrylate-PDMS composite latexes were confirmed by using FTIR spectroscopy, TEM, and SEM measurements, respectively. Thermophysics and heat resistance of the dried coatings based on acrylate-PDMS composite latexes were studied using DSC and TGA tests, respectively. Anticorrosion properties of the cured coatings based on acrylate-PDMS composite latexes were confirmed by potentiodynamic polarization test. With low surface tension, good toughness, excellent weather-proof properties, and good high and low temperature stability, the modified PDMS component can improve the performance of the traditional acrylate latex-based waterborne resin effectively, and the prepared acrylate-PDMS composite latexes can be used in heavy-duty anticorrosion applications.
