“…Polyurethanes are one of the most versatile polymeric materials which can be used in wide variety of industrial applications, e.g., as insulation materials, coating materials, and as adhesives . The use of natural renewable resources as feedstock to produce polymers has attracted increasing interest because of the high demands for environmental‐friendly products.…”

A series of castor oil‐based polyurethane (PU) with and without the incorporation of Halloysite nanoclay as filler are synthesized via addition polymerization of polycaprolactone‐diol (PCL) and methylene diphenyl diisocyante (MDI) as monomers. The PUs are characterized by using attenuated total reflectance‐Fourier transform infrared spectroscopy (ATR‐FTIR), thermogravimetric anaysis (TGA), differential scanning calorimetry (DSC), scanning electron microscope (SEM), and pencil hardness test. The TGA thermogram showed that the incorporation of castor oil affected the thermal stability of the PU matrices by 7–9% in reduction of the decomposition temperature; whereas the incorporation of Halloysite nanoclay into the PU matrices increased the thermal stability by 3–5% in the detection of higher decomposition temperature. The DSC thermograms of the castor‐oil based PU and castor oil‐based PU with Halloysite nanoclay showed reduction in glass transition temperature (Tg) by 13–33 and 8–14 °C, respectively as compared to pristine PU and castor‐oil based PU. It is envisaged that the reduction in Tg is caused by the non‐uniformity of dispersion of the Halloysite nanoclay throughout the PU matrices and hence, affected the mobility of the PU chains. The SEM images further confirmed the non‐uniformity of dispersion of the Halloysite nanoclay in the PU films. Pencil hardness test indicated that the PU films coated on glass slides had lower than 1H hardness.

“…As presented in Figure , all the UV‐cured PUA resins exhibit high tensile and impact strength (respectively, above 72 MPa and 18 kJ m −2 ) as well as high modulus (above 3.6 GPa). In the previous report, the tensile strength of the UV‐cured PUA prepared by Huang et al . can only reach the maximum value of about 24 MPa.…”

In this article, aiming to develop the high performance ultraviolet (UV)-curable resin used in the polymer matrix composite, a series of polyurethane acrylate (PUA) resins with the different numbers of allyl terminal groups were elaborately designed and synthesized, in which the contents of hard segments and soft segments were also adjusted simultaneously. The effects of allyl number on properties of PUA were systemically investigated. It was found that allyl number had the negligible effect on the processability as well as positive effect on thermal performances, and all PUA resins exhibited the low viscosity and rapid UV polymerization. Besides, with the change of allyl number in the range of 2-4, PUA resin casting with three allyls possessed the preferable mechanical properties such as 85.1 MPa tensile strength, 3.94 GPa tensile modulus, and 20.7 kJ m −2 impact strength. More importantly, the high strength and high modulus of the composite further demonstrated the wide potentials of the as-prepared PUA resin as the ideal resin matrix candidate for the fiber reinforced polymer composites.

“…The organic grouting materials such as polyurethane [9,10,11], epoxy resin [12], acrylamide [13], methacrylate [14], acrylate [15], and lignin [16] have been extensively explored as well. Among the aforementioned grouting materials, polyurethane has attracted widespread attention owing to its good flexibility, high permeability, strong adhesion, and easy manipulation [17,18,19], and is regarded as one of the most promising candidates. However, polyurethane grouting material still suffers from high price, flammability, poor barrier property, and thermal stability [20,21], which limits its practical applications.…”

Polyurethane/Red Mud Composites with Flexibility, Stretchability, and Flame Retardancy for Grouting

Flexibility, stretchability, and flame retardancy are of ever increasing importance in constructing grouting materials. Herein, a simple and effective strategy to make organic-inorganic composite grouting material in a “flexible, stretchable, and flame retardant” way was based on the excellent synergistic interactions among polyurethane prepolymer, red mud, polyethylene glycol, and trimethylolpropane. The resultant polyurethane/red mud composite grouting material with three-dimensional network structure presented a favorable flexibility, desirable compressive strength of 29.2 MPa at 50% compression state, and a good elongation at 15.1%. The grouting material was mainly composed of amorphous polyurethane and crystalline red mud, and its probable formation mechanism was reaction of prepolymer with H2O, polyethylene glycol and trimethylolpropane under vigorous stirring in the presence of catalyst. Furthermore, the grouting material possessed favorable thermal stability, flame retardancy and repairment performance for roadway cracks. This work may open a simple and convenient avenue for the massive engineering application of red mud and preparation of flexible organic-inorganic hybrid grouting material.
