Surfactants
ThermoplastiquesUne matière thermoplastique désigne une matière qui se ramollit (parfois on observe une fusion franche) d'une façon répétée lorsqu'elle est chauffée au-dessus d'une certaine température, mais qui, au-dessous, redevient dure. Une telle matière conservera donc toujours de manière réversible sa thermoplasticité initiale. Cette qualité rend le matériau thermoplastique potentiellement recyclable (après broyage). Cela implique que la matière ramollie ne soit pas thermiquement dégradée et que les contraintes mécaniques de cisaillement introduites par un procédé de mise en forme ne modifient pas la structure moléculaire.Index. décimale : 668.1 Agents tensioactifs : savons, détergents Note de contenu : 1.

MélamineLa mélamine, de nom chimique 1,3,5-triazine-2,4,6-triamine, est parfois dénommée cyanuramide ou cyanurotriamine. Sa formule brute est C3H6N6.
Les "résines mélamine-formaldéhyde" ou "mélamine-formol" (sigle MF) sont appelées "mélamine" dans le langage courant. Elles font partie de la famille des aminoplastes qui regroupe des résines thermodurcissables aminées, issues d'un comonomère tel l'urée ou la mélamine, parfois le thiocarbamide, le cyanamide hydrogène ou le dicyandiamide ; le second comonomère étant le formaldéhyde.

Revêtements -- Propriétés mécaniquesIndex. décimale : 667.9 Revêtements et enduits Résumé : In this study, a new hybrid alkyd resin was formulated using melamine-based hyperbranched polymer having 24 hydroxyl groups on its structure and relatively low molecular weight alkyd. The alkyd was synthesized using an oil mixture (40% linseed + 60% sunflower). Melamine was used as the core molecule for the hyperbranched polymer due to its excellent properties such as greater hardness, alkali and solvent resistance, and thermal stability. Melamine was first hydroxylated using formaldehyde and changed into hexamethylol melamine. This product was then twice hydroxylated with dimethylol propionic acid to obtain a hyperbranched polymer with 24 hydroxyl end groups. It was then reacted with low molecular weight alkyd resin at different proportions. The product had a low viscosity and could easily flow like oil. It is a solvent-free and water-free liquid. The ‘hyperbranched polymer/alkyd’ ratio affected physical properties of the liquid polymer and also the mechanical properties of the hardened polymer, which can be used for surface coating. The viscosity of the liquid resin decreases from 148 to 8.84 Pa.s as the hyperbranched-polymer-to-alkyd ratio is decreased from 1:3 to 1:24. On the other hand, the hardness of heat-treated resin decreases from 198 Persoz to 43 Persoz, respectively. That is, the increase in the amount of hyperbranched polymer in the resin increases hardness, whereas the increase in the amount of alkyd decreases it. The mechanical tests of hardened resins showed that all specimens passed conical mandrel bending test, and they all depicted high adhesion, and high abrasion and impact resistance. The specimens also had excellent gloss properties.

First, new four-component acrylic-modified alkyd resins based on 1,3-propanediol containing 40% of the equivalent amount of acrylic copolymer to alkyd resin were synthesized using the fatty acid method. The synthesized acrylic-modified alkyd resin was then dissolved in isopropyl alcohol (IPA) at various ratios and further diluted using distilled water at various ratios to obtain by-weight percentages of 70/50, 70/60, and 80/60 of solid content to IPA and water, respectively. Films of the modified alkyd resins were prepared, and cured at 150°C for 1 h, then their physical and chemical surface coating properties and thermal behaviors were investigated. The best results were obtained for the by-weight percentages of 80/60.

ThermogravimétrieIndex. décimale : 667.9 Revêtements et enduits Résumé : Urethane-modified alkyd resins were synthesized using the depolymerization intermediates obtained from simultaneous hydrolysis–glycolysis reactions of post-consumer poly(ethylene terephthalate) (PET) bottles with dipropylene glycol (DPG) and water. For this aim, first, the synthesis of a four-component reference alkyd resin having an oil content of 50% was synthesized by using tall oil fatty acid (TOFA), trimethylolpropane (TMP), phthalic anhydride (PA), and dipropylene glycol (DPG). The PET-based alkyd resins were also synthesized using different amounts and types of purified and fractionated depolymerization intermediates (water-insoluble fraction, WIF, and water-soluble and crystallizable fraction, WSCF) under the same reaction conditions. For the synthesis of PET-based alkyd resins, the depolymerization intermediates were used partially or completely instead of dibasic acid and/or diol components in alkyd resin formulations. In order to determine the optimum modification ratio for urethane-modified alkyd resin synthesis, the reference alkyd resin was reacted with toluene diisocyanate (TDI) at different molar ratios (NCO/OH: 1/1, 1/2, and 1/3), and the optimum NCO/OH ratio was determined as 1/1, according to the surface coating properties. And, then, all PET-based urethane-modified alkyd resins were prepared by the modification reactions of the PET-based alkyd resins with TDI at an optimum ratio. At the end of the study, it was observed that the use of waste PET intermediates (WIF or WSCF) did not cause any negative effects on physical/chemical surface coating and thermal properties ; on the contrary, some properties were obtained as superior than that of the reference resin. In conclusion, it seems possible to use PET-based urethane-modified alkyd resin could be used as a cheap, environmentally friendly, and relatively economic binder component in synthetic paint formulations. In the synthesis of urethane-modified alkyd resin, using a certain amount of waste PET intermediate instead of dibasic acid and/or diol component will reduce raw material costs and also benefit the environment by re-evaluation of recycled PET. Thus, it could be both possible to recycle of post-consumer PET bottles, which are a valuable waste, and to provide cheap raw materials without compromising its features for paint formulations. These results are remarkable in terms of sustainability and waste management besides are also important for the economy and paint industry.

vision des couleursIndex. décimale : 535.6 Couleur Résumé : In our modem society, we spend much of our time in indoor atmosphere where we are surrounded by coated surfaces. Due to their inherent nature these surfaces are not able to reflect a spectrum of Electromagnetic Energies which are vital for healthy living. Such deficiencies leads to several health issues like sick building syndrome (SBS), health disorder like migraine, dizziness, chest pain, irritation to eyes, throat and nose, vomiting, joint pain, acidity and chronic lung disease. From many research studies it can be emphasised that individuals at work in indoor environment suffer from depression, poor task performance and unhealthy relationship with other people around. Apart from other environmental factors light and colour are two important constituents which have profound effect on human health and well-being. For a paint formulator this impact of colour and light scattering ability of the coated surface on human health has become a critical consideration while formulating a coating. This paper reviews the impact of natural Electromagnetic Energies (EME) on human health and well-being and the impact of some popular shades on human behaviour. We conclude, for indoor living, the interaction of available lighting conditions and inherent nature of coatings used on the surfaces has profound impact on human well-being as it governs the available spectrum of energies. An inter-disciplinary approach in partnership with 'Lighting' industries is required to device solutions essential for human well-being. Note de contenu : - Electromagnetic spectrum
