Correlation of hardness with mfft and cpvc of latex / ceramic coatings / Ming Lei in JOURNAL OF COATINGS TECHNOLOGY (JCT), Vol. 75, N° 945 (10/2003)
[article]
Titre : Correlation of hardness with mfft and cpvc of latex / ceramic coatings Type de document : texte imprimé Auteurs : Ming Lei, Auteur ; L. E. Scriven, Auteur ; Lorraine F. Francis, Auteur Année de publication : 2003 Article en page(s) : p. 95-102 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Acétate de vinyle L'acétate de vinyle est l'ester de l'acide acétique (acide éthanoïque) avec le tautomère alcoolique de l'éthanal (acétaldéhyde) et de formule semi-développée, CH3COO–CH=CH2.
L'acétate de vinyle est préparé, en règle générale, en phase vapeur, en faisant réagir un grand excès d'acétylène sur de l'acide acétique (200 °C) en présence de catalyseurs au zinc et au cadmium). On obtient un liquide incolore à odeur très pénétrante qui ne se polymérise en polyacétate de vinyle (PVAC) qu'en présence de catalyseurs et donne des solides durs très stables à la chaleur. Il peut être copolymérisé avec d'autres composés vinyliques ou d'autres monomères.

Dureté VickersLa mesure de dureté Vickers se fait avec une pointe pyramidale normalisée en diamant de base carrée et d'angle au sommet entre faces égal à 136°. L'empreinte a donc la forme d'un carré ; on mesure les deux diagonales d1 et d2 de ce carré à l'aide d'un appareil optique. On obtient la valeur d en effectuant la moyenne de d1 et d2. C'est d qui sera utilisé pour le calcul de la dureté. La force et la durée de l'appui sont également normalisées.

Solutions aqueuses (chimie)Index. décimale : 667.9 Revêtements et enduits Résumé : Hardness, porosity, and microstructure of film-forming in polyvinyl acetate/alumina coatings from aqueous suspensions were investigated with a minimum film formation temperature (MFFT) bar, Vickers hardness tester, and scanning electron microscopy (SEM). The hardness of opaque composite coatings (alumina:latex = 1:2 by volume) increased abruptly at the MFFT of the latex, suggesting that the alumina particles did not change the latex film formation behavior and that the hardness measurement is an alterative to the optical criterion. Studies of coatings from latex particles that were smaller or larger than a common size of ceramic particles indicated that the composition of maximum hardness, called critical Vickers hardness concentration (CVHC), matched conventional critical pigment volume concentration (CPVC). More efficient polymer binding in the coatings from the smaller latex gave them higher peak hardness and CPVC. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=5563

Transports d'ionsIndex. décimale : 667.9 Revêtements et enduits Résumé : Water-based anti-corrosion coatings, which are environmentally-friendly replacements for organic solvent-based coatings, do not perform well enough for use in the most challenging corrosion environments. The high water absorption capacity of water-based latex films may reduce barrier performance by contributing to corrosive reactant/product transport. We seek to understand the coupled effects of water absorption and ion transport in hydrated latex films, and to propose mechanisms explaining these effects. Water absorption and ion transport in films immersed in deionized (DI) water were monitored by mass gain and electrical conductivity measurements, respectively. Despite very similar polymer compositions between films, large differences in water absorption and ion transport rates were observed and explained by percolating networks at latex particle boundaries which facilitate transport. A semi-continuum model with three-component diffusion and convection-like elastic relaxation supported the assumptions of the physical mechanisms governing water absorption and ion transport. The evidence of the coupled processes of water absorption and ion transport in hydrated latex films revealed in this study are useful for designing water-based coatings that provide high levels of corrosion resistance.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : With advancements in architectural coatings, the demand for antimicrobial coatings in this sector has increased significantly. The COVID-19 pandemic has also been a primary force behind the increased demand for and production of antimicrobial coatings. Typically, antimicrobial coatings are used to resist and decolonize microbial attacks such as biofilm formation, fungal contamination, and black mold formation. In this study, we synthesized a water-based antimicrobial polymer nanocomposite, I-P(MMA/BA), by blending an iodine complex with a poly (methyl methacrylate-butyl acrylate) latex with the aid of polyol and polyvinylpyrrolidone. Antimicrobial efficacy was evaluated in two habitats, namely planktonic and biofilm. Biomass studies indicated that iodinated latex nanocomposites and films show excellent antibacterial and antibiofilm activities. About 85–97% of biofilm formation was reduced by covering 15–30% of the area with iodinated latex film. The contact angle measurement of the iodinated latex-coated surface provides evidence of good hydrophobicity, which prevents stagnation of water over the surface. The developed dual-functional water-based iodinated nanocomposite displays great potential for inhibiting biofilm formation on surfaces when employed as a binder in paints.

Revêtements en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : The potentiometric titration of carboxylated methyl methacrylate latexes prepared with varying amounts of methacrylic acid showed that only very small amounts of their total acids copolymerized were neutralized at room temperature until the acid level was well above 10%. However, it was found that all the acids copolymerized were completely titrated either in a 50/50 water/ethanol mixture at room temperature or in water at high temperatures near their backbone polymer Tgs, regardless of their acid contents, as predicted from the existing theories on the alkaliswelling of carboxylated latexes. It was also found that these high-temperature alkali-swollen latex particles remained in the swollen state even after they were cooled down to room temperature and became film-forming at much lower temperatures. This discovery led to a new technology coined as a high-temperature water-extended latex technology. This new technology enabled us to develop VOC-free water-extended latexes of high-Tg polymers that would exhibit good film formation at ambient temperature and turn into hard and non-blocking latex films and latex-bound pigmented coatings upon drying. Particularly, when fugitive bases were used for neutralization at high temperatures, the resulting water-extended latexes became hard, non-blocking, and water-resistant binders upon drying.

Revêtements:PeintureIndex. décimale : 667.9 Revêtements et enduits Résumé : The real-time kinetics of film formation of a floor polish polymer latex coating has been investigated using dielectric measurements of the ionic conductance. Varying levels of ambient humidity were applied and had a dramatic effect on the drying rate, drying mechanism, and final film thermal and mechanical properties. At humidities below 30%, the drying curves followed a power law time decay with two distinguishable regions. The first region showed a drying rate dependence on the order of t^-10, while the second region showed a drying rate dependence on the order of t^-2. At higher humidities, the curves become more complex. At the highest humidities, film cracking was observed. Besides dielectric analysis, thermal analysis experiments were conducted that indicated film formation continues over very long times (months). The data also indicate that considerable residual stress remains in the dried films even after these long times.
