Effect of Lamellar Inorganic Fillers on the Properties of Epoxy Emulsion Cement Mortar
Huabing Li,Jiandong Zuo,Biqin Dong,Feng Xing 한국콘크리트학회 2020 International Journal of Concrete Structures and M Vol.14 No.3
Lamellar inorganic fillers have been used to improve the performance of polymer composites. In this paper, five kinds of lamellar inorganic fillers, including montmorillonite (MMT), mica, talc, glass flake (GF) and lamellar double hydroxide (LDH), were selected to modify epoxy emulsion cement mortar (EECM). The research evaluated the effects of the structure characteristics of lamellar fillers on the mechanical properties, water absorption and chloride ion permeability resistance of EECM, with comparison to granular ground calcium carbonate (GCC). Results indicated that lamellar fillers had no obvious superiority than GCC in the mechanical strength of EECM, even MMT caused the decline of the mechanical strength. However, lamellar fillers had improved the chloride ion permeability resistance of EECM compared with GCC, and they had the similar effect on reducing of water absorption except MMT. Although the low aspect ratio (AR) of the lamellar fillers benefited the increase of the strength and water resistance of EECM, the lamellar fillers with higher AR could improve the chloride ion permeability resistance of EECM more efficiently.

Halogen-free flame retardant tri(acryloyloxyethyl) phosphate (TAEP) optical resin was prepared using hydroxy ethyl acrylate (HEA) and phosphorus oxychloride and the chemical structure was characterized by Fourier transform infrared spectrometer and proton nuclear magnetic resonance spectrometer. Optical resins mixed by pentaerythritol tetrathioglycolic and TAEP with different S and P contents were obtained via click chemistry curing. The curing performance, thermal stability and flame retardant performance of the optical resins were analyzed by differential scanning calorimeter, thermogravimetric analyzer, and vertical burning tester, respectively. Additionally, the burned residual morphology of samples was investigated by scanning electronic microscopy, and the refractive indices of the optical resins were measured by an Abbe refractometer. The results revealed that increasing S content could improve the refractive indices of the resins; whereas, the flame retardant performances decreased. The optical resins with S content of 2% and P contents of 7.37% had refractive indices of 1.4935 and UL 94 V-0 flame retard level, respectively. The optical resins had good thermal stability and the 5% decomposition temperature reached up to 200.1 ℃.

Rice sheath blight (SB), caused by Rhizoctoniasolani (R. solani), is a major threat to rice productionworldwide. The molecular mechanisms of the SB resistancein rice are poorly understood. The transcriptomes of the SBresistantrice cultivar YSBR1 and the susceptible cultivarLemont were analyzed after R. solani infection. A total of7624 differentially expressed genes (DEGs) were identifiedat one or more timepoints in a cultivar. 5526 and 5618 DEGswere differentially expressed in Lemont and YSBR1,respectively. YSBR1 exhibited stronger and earlier transcriptionalresponse to R. solani than Lemont. Gene ontology enrichmentanalysis revealed that genes that encode cell wall-modifyingand glycosyl-degrading enzymes or anti-microbial proteinswere specifically induced in YSBR1 at 6 hpi. MapMananalysis revealed that more DEGs related with cell wall, β-glucanses, respiratory burst, phenylpropanoids and ligninwere highly induced by R. solani in YSBR1 than in Lemont. The results also showed that receptor-like kinases and jasmonicacid signaling may play important roles in host resistance toR. solani. This study highlights potential candidate genes andsignaling pathways involved in rice sheath resistance and canhelp to further clarify the mechanistic events underlyingresistance and susceptibility to R. solani.
