A stoichiometric amount of tetraethylenepentamine (TEPA) was added as a crosslinker to the blocked polyisocyanate dispersions resulting in one-package crosslinkable, waterborne urethane coatings. The samples were characterized by means of mechanical properties, chemical resistance, differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). The deblocking kinetics of the blocked polyisocyanates at different baking temperatures were studied.

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Acrylic and polyurethane aqueous dispersions have been used extensively in coating applications, both independently and as physical blends. The resulting coatings display a balance of properties from the inherent characteristics of acrylics and polyurethanes. Nonetheless, these properties often fall short of those predicted front the traditional rule of mixtures. In contrast, a process has been developed whereby acrylic monomers and urethane prepolymers are intimately mixed and mutually polymerized in an aqueous dispersion, thereby resulting in hybrid polymer dispersions. This process causes an interpenetrating network (IPN) of the polymers which subsequently display unique properties compared to standard acrylic, polyurethane, or macroscopically blended acrylic/urethane dispersions. These properties appear to be directly attributable to the acrylic-polyurethane hybrid morphology. Note de contenu : - EXPERIMENTAL : Materials - Procedures

Langues : Américain (ame) Catégories : Adénosine triphosphate L’adénosine triphosphate, ou ATP, est un nucléotide formé à partir d'un nucléoside à un triphosphate. Dans la biochimie de tous les êtres vivants connus, l'ATP fournit l'énergie nécessaire aux réactions chimiques du métabolisme, à la locomotion, à la division cellulaire, ou encore au transport actif d'espèces chimiques à travers les membranes biologiques. Afin de libérer cette énergie, la molécule d'ATP est clivée, par hydrolyse, en adénosine diphosphate (ADP) et en phosphate, réaction qui s'accompagne d'une variation d'enthalpie libre standard ΔG0′ de −30,5 kJ mol−1. Les cellules régénèrent ensuite l'ATP à partir de l'ADP essentiellement de trois manières différentes : par phosphorylation oxydative dans le cadre de la respiration cellulaire, par photophosphorylation dans le cadre de la photosynthèse, et par phosphorylation au niveau du substrat au cours de certaines réactions chimiques exergoniques, par exemple au cours de la glycolyse ou du cycle de Krebs. Ainsi, le corps humain ne contient à chaque instant qu'environ 250 g d'ATP mais consomme et régénère chaque jour de l'ordre de son propre poids en ATP.

Stabilité thermiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : In recent years, green environment protection has received widespread research interest. In this study, a green, bio-based compound, adenosine triphosphate (ATP), was introduced into the intumescent flame retardant system to improve the flame retardant properties of waterborne fireproof coatings. The flame retardant properties of the sample with 2 wt% ATP were characterized by fire resistance tests, thermogravimetric analysis, cone calorimetric analysis, and other tests. The results revealed that the 2 wt% ATP coating sample exhibited a reduced fire resistance temperature of approximately 73°C at 60 min compared with that of the blank sample (i.e., the unmodified sample), and the residual carbon increased from 28% to 36% at 800°C. Furthermore, the peak of the heat release rate and the total heat release for the sample with 2 wt% ATP were 7.87% and 14.10% lower than those for the blank sample, respectively. Additionally, the total smoke production and peak smoke release rate for the modified sample were 33.60% and 22.54% lower than those for the blank sample, respectively. Therefore, this work provides a good prospect for the application of bio-based ATP, which can be applied in the fabrication of fire-resistant and smoke-suppressive coatings for structural steel and also provides a simple and efficient strategy for green, bio-based flame retardants, which is expected to expand their application scope in fireproof coatings.

Transparence (optique)Index. décimale : 667.9 Revêtements et enduits Résumé : Synthesis, characterization, and coating performance of castor oil (CO)-based waterborne hyperbranched polyurethane acrylate (WHPUA) emulsions are highlighted in this work. Herein, a second-generation CO-based hyperbranched polyester (C20) was synthesized by introducing the renewable CO as a B3 core and dimethylolpropionic acid as an AB2 monomer via a pseudo-one-pot condensation procedure. Three types of CO-based WHPUA emulsions were prepared through the addition of the hyperbranched C20 with maleic anhydride (MA) and the isocyanate-bearing semiadduct (IPDI-HEA) at different MA/IPDI-IH molar ratios without the addition of any emulsifiers. The prepared emulsions were further formulated into UV-curable coating formulations and exposed to a medium-pressure mercury lamp. Consequently, the obtained UV-cured coatings exhibited outstanding adhesion performance, excellent transparency, and an acceptable degree of final double bond conversion. Owing to a relatively low concentration of hydrophilic units and a large number of acrylate functionalities in the waterborne oligomer, the obtained films were endowed with high crosslinking density and low hydrophilic nature, thus producing enhanced tensile strength, pencil hardness, water resistance, and chemical resistance. Due to their combination of renewable materials, a waterborne system and a UV-curing technique, these CO-based WHPUA emulsions offer promising opportunities to be used as environmentally friendly coatings.
