Flame-retardant and crosslinking modification of MDI-based waterborne polyurethane

A series of flame-retardant waterborne polyurethanes were synthesized with 4,4′-diphenylmethane diisocyanate and polyethylene glycol600 (PEG600) and modified with different level of diethylbis(2-hydroxyethyl)aminomethylphosphonate (fyrol-6); besides, 1,1,1-Tris(hydroxymethyl)propane was introduced as chain extender and crosslinking agent. The...

Influence of zinc borate on flame retardant and thermal properties of polyurethane elastomer...

The effect of zinc borate (ZnB) was studied on the flame retardant and thermal properties of thermoplastic polyurethane containing huntite-hydromagnesite. The flame retardant properties of thermoplastic polyurethane-based composites were investigated using limiting oxygen index, vertical burning test (UL 94), thermogravimetric analysis, and mass...

Rigid Polyurethane Foam Fabrication Using Medium Chain Glycerides of Coconut Oil and Plastics from...

Polycarbonate and polyurethane scraps from end-of-life vehicles were converted into liquid recycled polyols with hydroxyl number around 300 mgKOH.g-1 by using medium chain glycerides of coconut oil. The obtained polyols were used for preparation of low-density rigid polyurethane foams. It was found that up to 50 wt % of the virgin petrochemical...

Organic-inorganic hybrid linseed oil-based urethane oil wood coatings

To prepare alkoxysilane-functionalized urethane oil (AFUO) using linseed oil, 3-aminopropyltriethoxysilane (APTES) was first reacted with diisocyanate to obtain an NCO-terminating oligomer. The reaction was continued by adding linseed oil glyceride to form an AFUO prepolymer. The auto-oxidative drying coating was obtained after adding a metal dryer...

Malleable and Recyclable Poly(urea-urethane) Thermosets bearing Hindered Urea Bonds

Poly(urea-urethane) thermosets containing the 1-tert-butylethylurea (TBEU) structure feature a reversible dissociation/association process of their covalent linkages under mild conditions. Unlike conventional thermosets, TBEU-based poly(urea-urethane) thermosets maintain their malleability after curing. Under high temperature (100 DEGC) and applied...

Dynamic Glass Transition of the Rigid Amorphous Fraction in Polyurethane-urea/SiO2 Nanocomposites

We report molecular dynamics in the rigid amorphous fraction (RAF) of the polymer bound at the interfaces with nanoparticles in polymer nanocomposites and calculate the glass transition temperature, Tg, for this bound layer of polymer. We follow the '3-phase-model' for semicrystalline polymers where the polymer matrix consists of the crystalline...
