Preparation and properties of waterborne polyurethaneurea consisting of α, ω-dihydroxypoly[(3,3,3-trifluoropropyl)methylsiloxane] units
关键字：waterborne polyurethaneurea consisting of α, ω-dihydroxypoly[(3,3,3-trifluoropropyl)methylsiloxane] units
A series of polyurethaneurea (PUU) aqueous dispersions modified with α, ω-dihydroxypoly [(3,3,3-trifluoropropyl) methylsiloxane] (PTFPMS) were prepared. These anionic-type aqueous dispersions were stable at ambient temperature and showed excellent high-tempe...

(Industrial & Engineering Chemistry Research) Synthesis of a Waterborne Polyurethane-Fluorinated Emulsion and Its Hydrophobic Properties of Coating Films
In this study, a novel waterborne polyurethane-fluorinated acrylic (WFPU) hybrid emulsion was synthesized and introduced. The cross-linker aziridine was used to enhance the film-forming capacity and mechanical property of WFPU. FTIR and XPS results confirmed that WFPU latex was successfully prepared. WFPU has an excellent hydrophobicity, resulting in an obvious increasing of water contact angle ...

(Prog. Org.Coat.)Synthesis of bio-based unsaturated polyester resins and their application in waterborne UV-curable coatings
In this paper, three bio-based unsaturated polyesters were synthesized from itaconic acid and different diols which could be derived from renewable resources. Their chemical structures were confirmed by FT-IR, 1H NMR and acid value as well as hydroxyl value. Waterborne UV curable networks based on these polyesters were manufactured and their mechanical properties, thermal stability and coating p...

(Prog. Org. Coat.)High Bio-based content waterborne UV-curable coatings with excellent adhesion and flexibility
A series of bio-based unsaturated polyesters was synthesized by melt polycondensation of itaconic acid with 1,4-butanediol and glycerol. Their chemical structures were confirmed by FT-IR, 1H NMR, acid and hydroxyl values. Waterborne UV curable dispersion coatings based on these polyesters and acrylated epoxidized soybean oil (AESO) were formulated. The average particle size and their stability b...

Mechanical Properties of Oil Filter Paper Impregnated by a Novel Waterborne Novolac Epoxy Emulsion
A novel cationic waterborne epoxy emulsion for oil filter paper was synthesized. Hydrophilic groups were introduced into a multifunctional bisphenol-A novolac epoxy resin (NEP) by chemical modification, while maintaining the epoxy groups as many as possible, which were neutralized to form the equably water dispersed epoxy resin. The structure of modified NEP in different rate of ring-opening was c...

An emulsifier-free core–shell polyacrylate/diacetone acrylamide emulsion with nano-SiO2 for room temperature curable waterborne coatings
An emulsifier-free core–shell polyacrylate emulsion, containing nano-SiO2 nanoparticles in the core and diacetone acrylamide (DAAM) in the shell, has been successfully prepared by emulsifier-free seeded emulsion polymerization.
The effects of reaction temperature, dropping time, nano-SiO2 and initiator contents, and variation of the composition of core monomers on the amount of coagulum, pa...
