Abstract In order to solve weakness, undesirable abrasion resistance, and hardness of a water-based wood coating film, modified surface nano-alumina was made in the water-based wood coating. The effect of surfactant type and amount on the performance of nano-alumina slurry was investigated. How the performance of the polyacrylate wood coating was affected by the size, amount, and mixing method of nano slurry was studied, as well as the characterization of nano-alumina slurry and modified polyacrylate wood coating. The results showed that, by compounding the non-ionic surfactant polyoxyethylene octylphenol ether (OPEO) and anionic surfactant sodium polyacrylate of surface modification of nano-alumina, the nano-alumina slurry had excellent performance and good stability when the amount of nano-alumina was 0.6 wt% and 3.2 wt%, respectively. When 1.5 wt% of nano slurry was mixed with the water-based polyacrylate emulsion to a hybrid during the pre-emulsification phase, the wood coating film had high performance, and good abrasion resistance and hardness.

In the paper, the surface modification of nanotitanium and its effect on the antibacterial properties of waterborne wood coating were studied. The effect of the type and amount of surfactant (system) and the ultrasonic treatment time on the property of nanotitanium and the effect of the dosage and adding method of nanoslurry on the properties of water-based wood coating were both investigated. The nanotitanium slurry made in the optimum conditions was also characterized. The results showed that nanotitanium slurry with excellent performance was obtained when 0.5wt% polyoxyethylene octylphenol ether and 3wt% sodium polyacrylate were used and ultrasonic treated 5h. It also showed that the waterborne wood coating with excellent drying performance and antibacterial property was got when 1.5wt % nanoslurry was mixed to water-based emulsion to hybrid. Under the conditions, the antibacterial rate against Escherichia coil and Staphlococcus aureus reaches to 95%.

Water Based

A fast water-based ultraviolet light (UV) curing polyurethane-acrylate (PUA) wood coating was prepared in the laboratory, and applied on oak (Quercus alba L.) at different coating amounts. The PUA wood coating can be fast cured within 22 min, which highly improved the drying speed compared to normal water-based wood coatings (often higher than 35 min). The coating amounts affected the coating properties after curing on oak. With the increase of coating amount, the adhesion, hardness and gloss value of surface increased to different extents. Meanwhile, the surface of sample became smooth gradually because the voids of the oak were filled. Thus, higher coating amount resulted in better coating properties. However, no significant increase of penetration depth was found. During curing, the hydroxyl groups of the wood reacted with the coating. The optimal parameter in this study was the coating amount of 120 g/m2, where the adhesion reached 1 (with 0–5% cross-cut area of flaking along the edges), with the hardness of 2H and the gloss of 92.56°, which met the requirement of Chinese standard GB/T 18103–2013, and could be used for engineered wood flooring.

Different Content

Water-based polyurethane forms continuous and dense film after fully drying. Ink is lowly absorbed by PU film, affecting drying rate and color reproduction. In order to improve the absorption of ink on PU film, PU/nano alumina compound was prepared by adding nano alumina in PU and stirring at high speed. PU ink absorption coating was got by being coated on the substrate. The influences of different content of nano alumina to transmittance of coating and solid density of color blocks were researched. The influences of soft and hard segment of PU to image resolution and water resistance were also researched. It can be seen that transmittance reduces when content of nano alumina increases. Droplets spread less when using PU of hard segment and image resolution and solid density are also higher. At the same time, water resistance of solid blocks is much better when printed on PU of hard segment.

Giant magnetoimpedance (GMI) effect is a powerful technique for magnetic label detection. Co-based amorphous ribbons are cheap materials showing high GMI effect at low operation frequencies for close to zero magnitostriction compositions. In this work magnetic properties and GMI were studied for CoFeMoSiB amorphous ribbons in as-quenched and surface modified states without and in the presence of water-based ferrofluid with electrostatic stabilization of γ-Fe2O3 nanoparticles. Surface modification by ultrasound treatment resulted in appearance of round defects with average diameter of about 150 micrometers. The GMI difference for as-quenched ribbons in absence and in the presence of ferrofluid was measured for the frequency range of 0.5 to 10 MHz. Although proposed surface modification by the ultrasound treatment did not improve the sensitivity limit for ferrofluid detection, it did not decrease it either. Observed changes of GMI are useful for understanding of functionality of GMI biosensors.

Abstract This study is about preparing different paper substrates with chemically stable hydrophobic and superhydrophobic surface coatings through spraying a mixture of poly(dimethylsiloxane) (PDMS) and inorganic particles. The method is easy to implement, reproducible and requires inexpensive starting materials. Non-colored and colored types of (i) raw paper (UC), (ii) glossy coated paper (GC) and (iii) matte coated paper (MC) surfaces were selected for surface modification through the coating application. Both water-based ink (WB) and solvent-based ink (SB) formulations were used to dye substrate surfaces. Investigations including surface wetting, optical and physical properties of the coated paper substrates revealed that the coating application method proposed is a promising lacquer alternative for packaging purposes.
