Epoxy vinyl ester resin for wind turbine blade

Thermosetting Resin (2009)

Liu Zuo-zhen

The development situation of wind power generation and forming process and requirement of wind turbine blade were briefly introduced.MFE-VARIM-200 epoxy vinyl ester resin for wind turbine blade was developed.The viscosity,gel time,curing shrinkage rate and properties of cured product were tested.The results showed that the viscosity of MFE-VARIM-200 was lower than 0.2 Pa·s at 25 ℃.The gel time was longer than 2 h and the linear shrinkage was less than 0.3%.MFE-VARIM-200 met the vacuum infusion process requirement and the mechanical properties of cured resin could meet the requirement of matrix resin of wind turbine blade.

Durable, self-cleaning and anti-fouling superhydrophobic coating based on double epoxy layer

Materials Research Express (2022)

Xiang Li Hua Liu Yingbin Zhang Liu Zuo-zhen

Abstract The practical application of superhydrophobic coatings has been greatly restricted due to the complicated preparation and fragile hierarchical structures on the surface. In this study, we prepared a robust superhydrophobic coating with a double-layer structure via a low-cost and facile method, adhering the non-wettability layer composed of silica nanoparticles and fluorine-modified epoxy resin to a binder resin layer on aluminum. The fluorine-modified epoxy resin with low surface energy can fix the silica nanoparticles after curing and cross-link with the adhesive layer. When the SiO 2 content in the surface layer is 40%, the water contact angle (WCA) of the coating is 162°, and the sliding angle (SA) is 2°. In the mechanical performance test, the durable coating can remain superhydrophobic even after 260 cycles of friction or 160 cycles of tape peeling. In addition, the superhydrophobic coating with self-cleaning and anti-fouling properties also has the performance of acid-base solution resistance. Hence, the combination of the rough layer and the adhesive layer makes the practical application of artificial superhydrophobic coatings possible.

Effects of inhibitors on the storage life and curing kinetics of novolac epoxy vinyl-ester resin

Thermosetting Resin (2012)

Liu Zuo-zhen

The best complex inhibitor of novolac-epoxy vinyl-ester resin(NEVER)was determined from nitrogen heterocyclic compound,phenothiazine,hydroguinone and benzyl triethyl ammonium chloride by orthogonal test.The variety of double-bond after heat storage and curing reaction kinetics of NEVER with the complex inhibitors were investigated by DSC and FTIR.The insoluble content of the cured product was tested.The results showed that the best complex inhibitor was composed of 0.03% nitrogen heterocyclic compound and 0.03% phenothiazine(based on the NEVER mass) and the storage life of NEVER at 80 ℃ was increased from 11 h to 60 h.The residual percentage of total C==C doublebond was 63.7% after 50 h at 80 ℃.The complex inhibitor had a good role.The apparent activation energies of resin was increased from 79.00 kJ/mol to 87.44 kJ/mol.The complex inhibitor did not affect the the curing degree of the final product.

Fast fabrication of silicone-modified polyurethane/SiO₂ composite superhydrophobic coating with excellent anti-icing and self-cleaning behaviour

Materials Research Express (2020)

Huan Liu Li Xiang Lina Lv Liu Zuo-zhen Jianding Chen

Abstract The superhydrophobic coating has many excellent properties, but due to the limitation of poor surface mechanical stability and sophisticated preparation engineering, it is challenging to realize large-area application. In this study, a robust superhydrophobic coating with excellent performance was prepared by a simple and fast method. The modified silica nanoparticles was sprayed on the hydrophobic polyurethane coating, and the superhydrophobic surface with a water contact angle of 160° and sliding angle of 2° was successfully prepared after curing under UV lamp for 3 min. The coating can be applied to the surface of all kinds of substrates, and it still has a static water contact angle of 150° after 400 cycles of friction on 500 mesh sandpaper. Furthermore, the coating with verified self-cleaning and anti-icing properties exhibits superhydrophobicity to strong acid and alkali solutions. This simple, fast and environmentally friendly preparation method is expected to realize the wide application of superhydrophobic coatings.

Adsorption Characteristics of Lycopene on Macroporous Resin HZ816

Xiandai shipin keji (2009)

Lei Zhang Xu HuanXin Liu Zuo-zhen

Experiments were carried out to study the adsorption kinetics and thermodynamics of lycopene on macroporous resin HZ816,and the speed control model of the adsorption were also studied.The results showed that the adsorption fitted very well to the first order kinetics equation and intra-particle diffusion equation,and the adsorption process was affected by both film diffusion and intra-particle diffusion.The experimental isotherms data appear to follow the Freundlich isotherm equation,with ΔH0,ΔG0 and ΔS0.,which indicated that the adsorption process of lycopene on macro porous resin HZ816 was a spontaneous,entropy driven,exothermic and entropy increased process,belonging to the physical adsorption.
