“…Incorporating organic thermal insulation materials with inorganic thermal insulators has brought broad interests, with the purpose of enhancing the thermal insulating property. In this research, foamed phenolic materials, as organic insulator, has been incorporated with sulphoaluminate cement-based composites due to its good thermal insulating ability, low density, high porosity, excellent alkali resistance, good fire resistance, low cost, and being commercially available [22,23,24]. But, to the best of our knowledge, the incorporation of phenolic with sulphoaluminate cement-based materials has been very little reported as yet.…”

Foamed concrete materials based on sulpoaluminate cement were prepared by the chemical foaming method. The effects of water–cement ratio, foaming agent, and foaming stabilizer on the mechanical and thermal properties of foamed concrete were studied. Meanwhile, a portion of cement was replaced with foamed phenolic particles to further optimize the performance of foamed concrete; the results show that when the water–cement ratio was 0.53, the foaming agent content was 5%, the foam stabilizer was 1%, and the substitution of phenolic particles was 20%, the performance indexes of foamed concrete were the best. Methods, describing briefly the main methods or treatments applied: dry density was 278.4 kg/m3, water absorption was 19.9%, compressive strength was 3.01 MPa, and thermal conductivity was 0.072 W/(m·K). By the pore structure analysis of the foamed concrete suing Micro-CT, it was found that when the replacement amount of phenolic particles was 20%, the pore size of foamed concrete was relatively uniform, the minimum D90 was 225 μm respectively. The combination of organic and inorganic matrix and optimized pore structure improved the performance of foamed concrete.

“…The char layer began to swell. The foamed char on the front side hampered the heat delivery to the back side and then foamed char interrupted combustion chain reaction so as to delay combustion speed of the whole materials . The temperature reduced a little, and then remained constant for a long time.…”

Polyphosphate ester (PPAE) made from poly(phosphoric acid), pentaerythritol, and 1,3‐butylene glycol has been synthesized. The PPAE reacted with dimethyldichlorosilane (DMDCS) to improve its thermal stability and flame retardancy. Four silane‐modified polyphosphate esters (SiPPAEs) were obtained. FTIR, 31P NMR, and 29Si NMR results showed that the SiCl bond of DMDCS could react with the COH and POH bonds of PPAE, producing SiOC and POSi bond in SiPPAEs. Different transparent coatings were obtained by mixing the PPAE and SiPPAEs with amino resin. The results of TGA showed that the stability of SiPPAEs was higher than that of PPAE. With the increase of silane content, the thermal stability of the coating increased. As the silane content increased within a certain range, the fire resistance and expansion coefficient increased. But too high silane content had adverse effects on the expansion and reduced the overall insulation effect. The digital photos and SEM/EDX microphotographs of coatings after combustion showed that silica segments could enriched in the surface to form a hard protective layer to prevent further degradation of the char layer. © 2018 Wiley Periodicals, Inc.

“…In addition, they are made of bromo-silicon glass, which makes them chemically inert. Due to this facts, glass microspheres have many applications in the processing of plastics, among others, to reduce the mass of products in which the content of glass microballoons reaches 40-60% creating syntactic foams [1][2][3], reduce the thermal conductivity of plastics [4,5], improve dielectric properties [6], acoustic properties [7] or as flame retardant additives [3,8]. However, the mechanical properties of polymer composites decrease, with glass microsphere loading [5,9,10].…”

Hybrid composites of unsaturated polyester resin with the addition of glass microspheres and bentonite modified with a quaternary ammonium salt were obtained. The content of bentonite in composites was 3 wt %, while glass microspheres varied in the range of 5-15 wt %. The effect of the addition of glass microspheres on the rheological and mechanical properties of unsaturated polyester resin composites containing modified bentonite was investigated. On the basis of the obtained results, it was found that the optimum content of glass microspheres in polyester composites at which a clear increase in the value of most mechanical parameters was achieved, is 15 wt %. The Young's modulus, flexural modulus, tensile strength, and Charpy impact strength increased by 14.7, 38.7, 17.7 and 25%, respectively, compared to the unmodified resin. On the other hand, with relation to the sample containing 3 wt % of bentonite, a significant improvement was achieved only in the case of the flexural modulus and impact strength, amounting to 16.5 and 36.0%, respectively. In addition, composite with 15 wt % of glass microspheres was characterized by a smaller, by about 25%, flexural strength in relation to the unfilled resin and resin with 3 wt % of bentonite. In turn, rheological studies have shown that as the content of glass microspheres increased, there was an increase in viscosity and a decrease in gelation time in relation to the reference sample and the sample with 3 wt % of bentonite.
