Application of modified phytic acid as flame retardant in cellulosic paper
نویسندگان
چکیده
A flame retardant containing phosphorus and nitrogen was synthesized using phytic acid dicyandiamide, it subsequently used to prepare flame-retardant cellulosic paper via an impregnation method. Vertical limiting oxygen index (LOI) were evaluate the retardancy of paper. The modified characterized with Fourier transform infrared spectroscopy (FTIR), thermogravimetry (TG), X-ray diffraction (XRD), scanning electron microscopy (SEM). When concentration 20%, char length treated decreased from 12.5 cm 4.1 cm, LOI value increased 19.6% 41.5%, tensile only 3.66% lower than that control judged have good effects on

Graphene phosphonic acid as an efficient flame retardant.
We report the preparation of graphene phosphonic acid (GPA) via a simple and versatile method and its use as an efficient flame retardant. In order to covalently attach phosphorus to the edges of graphene nanoplatelets, graphite was ball-milled with red phosphorus. The cleavage of graphitic C-C bonds during mechanochemical ball-milling generates reactive carbon species, which react with phospho...

Lignin-Modified Carbon Nanotube/Graphene Hybrid Coating as Efficient Flame Retardant
To reduce fire hazards and expand high-value applications of lignocellulosic materials, thin films comprising graphene nanoplatelets (GnPs) and multi-wall carbon nanotubes (CNTs) pre-adsorbed with alkali lignin were deposited by a Meyer rod process. Lightweight and highly flexible papers with increased gas impermeability were obtained by coating a protective layer of carbon nanomaterials in a r...
متن کاملUrinary Tetrabromobenzoic Acid (TBBA) as a Biomarker of Exposure to the Flame Retardant Mixture Firemaster® 550
BACKGROUND Firemaster® 550 (FM550) is commonly added to residential furniture to reduce its flammability. Recent toxicological evidence suggests that FM550 may be endocrine disrupting and obesogenic. OBJECTIVES Our objectives were to develop methods to assess exposure to FM550 in human populations and to identify potential routes of exposure. METHODS Using mass spectrometry methods, we deve...
