Polyurethane-acrylic composite emulsion was synthesized by swelling polymerization with aqueous polyurethane dispersion as seed, and acrylic as monomers. The obtained polyurethane-acrylic (PUA) composite emulsion were characterized by means of IR spectra, and the results showed that the obtained emulsion was hybrid emulsion of polyurethane and acrylic, which had smaller particle size and higher viscosity and was more suitable for the preparation of ink. The obtained water-based PUA emulsion and alkyd resins were used as ink binder. The obtained water-based ink had good water resistance, color density, gloss and friction fastness.

And Performance

In order to study the dispersion and performance of tartrazine aluminum lake, 7 kinds of water-based resins are used to form disperse system. These systems are enviroment friendly (low VOC) and use edible yellow lake as colorant. If proper adjustment is added, these disperse systems can be made into ink and paint. The application field should be printing or coating on all the food or drug packages, toys and decorate materials, which will improve social safe level. Colorant, resin, wetting agent, co-solvent, emulsifier, and deionized water are mixed at certain ratio and pre-dispersed for 15min, then dispersed in GJ-2S high speed sanding mill for 3h. Size distribution, PDI, color characteristics (reflectance spectroscopy and color density), glossiness, abrasion performance, and stability are studied. Results demonstrate particle size of disperse system is 338.1~595.3nm (PDI<0.3) and changed to 428.6~551.2nm after 5 days or so. Reflectance spectroscopy is close to PANTONE standard yellow. Glossiness is referred as Gs(60°)≥32°. Viscosity is 0.2~2Pa·S. Relative stable disperse system is prepared.

Printing Ink

The performances of three kinds of water-based pigment inks were compared and studied, which include self-made ink, original printing ink and compatible ink. Art paper, matte paper and white card paper were used as the substrates. Testing the contact angle of ink droplets, the spreading, wetting, and drying rate of inks were investigated. The color density and CIE L*a*b* values of the printed samples were measured, to evaluate the hue error and color gamut. The water resistance was studied with corresponding experiments. The result indicates: self-made water-based pigment ink has the smallest contact angle on coated paper, showing a faster drying rate. Its color gamut is similar to the original printing ink on art paper, and the hue error is low. Through the water resistance test, the color density measured on art paper and matte paper had no changes, without color dissolving and color fading, showing good water resistance applicability.

A series of fluorine-modified acrylate resins used in water-based ink were synthesized by emulsifier-free semicontinuous seed emulsion polymerization with Hexafluorobutyl acrylate (G01) as a functional monomer and 2-Acrylamido-2-methyl propane sulfonic acid (AMPS) as a reactive emulsifier. The resins were characterized by Fourier transform infrared (FT-IR) spectra, particle size and distribution (PSD) analysis, contact angle (CA), mechanical stability, freeze-thaw stability and electrolyte stability, respectively. The fluorine-modified acrylate resin with 15% G01 and 3% AMPS had excellent water resistance, stabilities and narrow particle size distribution that it could be applied to the field of water-based ink.

Before And After

Polyurethane is a polymer adaptable to different scientific and industrial requirements; nevertheless it is also extremely susceptible to UV radiation, which compromises the physical and mechanical functionality. In this framework, our study investigated the effect of waterborne polyurethane dispersion (WPUD) applied to a polyester (PET)-based fabric, through the impregnation method, on the puncturing and water resistance of the pristine material, before and after UV weathering. Results confirmed an increment of both features in the prepared fabrics, attributed to the PUR textile treatment; but a partially loss of the gained properties in the samples due to the UV weathering. In order to improve the efficiency of the impregnating dispersions, in protecting the durability of the treated materials, the addition of different UV light stabilizers, or/and of crosslinking agent into WPUD was also tested. From the experimental data, it can be concluded that formulations based on WPUD, containing both the crosslinker and UV organic absorber, have displayed an increment of their perforation and water resistance for the treated samples with respect to the starting textile, and contemporary have preserved the features against the UV light. Finally, microscopic and spectroscopic analyses have been performed as further characterization techniques of the samples surface.

AbstractHematites obtained by heating goethite gave different IR absorption spectra depending on the temperature of formation. Hematites formed between 250–600°C consisted of lath-like crystals (average size 0.4 ×0.08 µm) and showed, in accordance with theoretical predictions, very similar IR spectra whose absorption bands could all be assigned to surface mode vibrations. However, significantly different IR spectra were given by hematites formed between 700–950°C, the differences being correlated with variations in the size and shape of the particles. Differences observed in the IR spectra of powder hematite do not therefore justify new names for the mineral, as have been proposed in the literature.

The Cross

In this paper, the cross-linked micro-gel polymer between acrylamide (AM) and N, N-Methylenebisacrylamide (MBA) was synthesized by dispersion polymerization. The initiator and crosslinking agent concentration were used to control the particle size of micro-gel polymer. The filtration property and mechanism of micro-gel were investigated comprehensively. The characteristics of micro-gel were checked by means of Fourier transform infrared spectroscopy, thermogravimetry, transmission electron microscopy, and particle size distribution, respectively. The results indicated that the cross-linked micro-gel polymer exhibited several outstanding merits, such as thermal stability (up to 200 °C), filtration control and rheological property. Microstructure analysis and particle size distribution examinations showed that the scale of micro-gel polymer was micro, which is in accord with design. Rheological tests demonstrated that the nonlinear structure of micro-gel polymer showed less impact on the apparent viscosity. The anti-high temperature property of micro-gel polymer was better than poly anioniccellulose (PAC) and asphalt widely applied in drilling fluid for anti-high temperature fluid-loss additive. As a result, the cross-linked micro-gel polymer had great potential to be applied in high temperature water-based mud.
