Active enzymes and other active biomolecules sequestered in paints and coatings have the potential to provide one of the more unique surface coatings yet identified. We report here the design and characterization of biological additives for latex coatings which impart catalytic detoxification or biodefensive capabilities to surfaces. The concept has been verified by the application of catalytic surfaces in the remediation of organophosphorus (OP) compounds, which include many of the commonly used pesticides as well as the most dangerous chemical warfare agents. The strategy for manufacture of these biocatalytic coatings involves the coupling of the power of biology with off-the-shelf, environmentally friendly paints. In this study, the entrapment of the biocatalyst in a latex coating is verified by analysis of the catalytic parameters for the enzyme in the coating. An estimation of the coating's operational and storage stability is also provided. Given the knowledge of the stability and activity of native and modified organophosphorus hydrolase (OPH, EC 3.1.8.1), the initial model system in the development of catalytic coatings is the OPH-catalyzed hydrolysis of paraoxon, demeton-S and diisopropylfluorophosphate, as well as neurotoxic chemical warfare agents. Success with these enzyme-substrate pairs will be used as the base for the incorporation of other biocatalysts into films and coatings.  相似文献

Coating failure through loss of adhesion is a common occurrence with latex paints especially when applied to previously painted alkyd surfaces. Wet adhesion promoters are used by the industry to overcome these deficiencies. This paper provides an overview of the technical effort at Cytec which has led to the discovery of a series of new wet adhesion monomers. Three such monomers have been under active development. At least one of these is expected to be available in developmental quantities later this year. These monomers are targeted at improving the wet adhesion performance of exterior and interior latex paints which are frequently exposed to moisture due to rain and/or high humidity. They have been incorporated into latex polymers which, when formulated into exterior latex paints, show excellent wet adhesion properties. Wet scrub test results on aged alkyd coated Laneta panels are discussed, along with comparative data on a currently available monomer.  相似文献

The estimate by differential scanning calorimetry of the enthalpy of thermal decomposition of the organic fraction in a complex material can be used, in proper conditions, for evaluating the concentration of the organic components. The application of this technique of thermal analysis to latex paints aimed at identification of binder content is discussed in this paper. On the one hand it gives good results on binder content estimate; on the other hand it highlights some aspects of the thermal decomposition of polymers enclosed in an inorganic matrix. The phenomena of thermal decomposition are studied for the main components of latex paints, i.e. for polymers, and for complete paint formulations. The materials considered include widely used binders for the manufacture of latex paints such as vinyl acetate/Versatate copolymers and styrene/acrylic copolymers, rheology modifiers such as cellulose ethers and other standard components of latex paints. Formulations representing typical latex paints with different binder content and simplified polymer/filler systems are considered. Although decomposition paths are very different for different polymers and for the same polymer in different concentrations, the overall heat output is consistent and proportional to the amount of polymer in the sample. Therefore identification by DSC measurements of the binder content in a latex paint appears as a feasible technique.  相似文献

乳胶漆的制造据笔者来看,乳胶漆是一项从实验室(从试配方到定配方)到检测室(从辅助试和定配方到检测产品)的重头戏。其制造过程比较简单,甚至是相当简单。但是,制造过程的硬、软件一定要起保障作用:保障实验室成果的准确再现。这保障有两个方面:硬件保障洁净和卫生;软件保障最大限度发挥每一个组分的作用。乳胶漆介质是水,要保障洁净,全套设备,包括容器、设备、管道和工具必须是不锈钢制成。保障卫生,要按时清理、消毒(包括厂房),防止微生物孪生,对乳胶漆构成污染并祸及产品质量。软件则指操作规程,工艺简单,规程也不会…  相似文献

Latex paints contain several types of particles including polymer binder, primary pigment, extenders, and colorants. When the paints contain associative thickeners, control of particle dispersion can be very complicated due to the interaction of the particles with dispersants, surfactants, and the associative thickener itself. In particular, dispersion of the pigments can act independently of dispersion of the binder particles. The consequences of this situation are manifested in the physical properties of the paint and of the films it forms. This paper describes these interactions in terms of their colloid chemistry and shows the consequences of additive choices on the particle dispersion and also the optical properties of model paint films. Presented at the 2006 FutureCoat! conference, sponsored by the Federation of Societies for Coatings Technology, in New Orleans, LA, on November 1–3, 2006.  相似文献

A model is developed for predicting long‐wavelength nonuniformities in the thickness of drying latex paint films. The model includes the effects of temperature, latex particle volume fraction, surface surfactant density, bulk surfactant density, and several material and environmental factors. After the model is simplified by applying the lubrication approximation, equations for spatially independent base state solutions are derived. The base state solutions describe a drying latex paint film of uniform thickness. The equations for the base states are solved numerically and a linear stability analysis is conducted. This analysis indicates that evaporation, slow surfactant kinetics, low initial surface tension, substrate permeability, and high initial latex particle volume fractions destabilize the uniform film, while fast surfactant kinetics, high initial surface tension, and high viscosity are stabilizing. © 2017 American Institute of Chemical Engineers AIChE J, 64: 1841–1858, 2018  相似文献
