“…Aerogel is a new porous function material with extremely high porosity and low thermal conductivity (Reim et al , 2004). Hollow glass microsphere is a rigid porous bead containing inert gas, which has many excellent properties such as low thermal conductivity, low density, high and low temperature resistance, heat insulation, high electrical insulating strength (Zhao et al , 2020). Therefore, silica nanoparticles 5%, HGMS5% and aerogel 5% were, respectively, added into the silicone resin, and the viscosity was increased with the increasing of the concentration of fillers, as shown in Figure 1.…”

Purpose The purpose of this paper is to develop a coated glass fiber fabric which can be used as the outer shell of firefighters' protective clothing and replace aramid fabric. Design/methodology/approach The silicone resin with excellent heat resistance was selected as the base solution. Silica nanoparticles, mica powder and ferric oxide were added into the coating solution, which was coated on the glass fiber fabrics. The vertical burning, thermal protective performance (TPP) value, second-degree burn time and water repellency of the coated fabrics were characterized. Findings Results showed that the dosages of the thickening filler were in the range 4%–6%; the coating solution has good viscosity. The optimal composition of fillers added in the silicone resin is silica nanoparticles 6%, ferric oxide 5% and mica powder 6%. The TPP value of the optimum coated fabric is 413 kW·s/m2. The second-degree burn time is 4.98 s, which is obviously higher than that of the original glass fiber fabric (3.49 s) and that of the aramid fabric (3.82 s). The coated fabric has better thermal stability than aramid fabric. Originality/value The production cost of this coated glass fiber fabric was much lower than that of the aramid fabric.

“…105,106 Using slightly different processes, Chen and Jian disclosed the chemical degradation of silicones in acidic media containing formamide or dimethylformamide, and a mixture of sulfonic and sulfuric acid at 200-280°C. 107,108 In 1996, Knies developed an inexpensive method of depolymerizing addition-cured silicones into volatile siloxanes and fillers using a small amount of acid. The process consists of three steps: first, a solvent-based solution of strong Bronsted acid is introduced into the silicone rubber vulcanizate; second, the solvent is is removed; and finally, the silicone rubber vulcanisate is heated to a temperature of at least 350°C.…”

“…The introduction of HGMs has been reported to improve the fire safe performance of thermoplastic polyurethanes (TPUs) 7 . The preparation of hollow glass microsphere/silicone rubber composite material with a transition layer of silicone resin has also been reported 8,9 . The strong H‐bond interaction of silica surface with PDMS, is expected to lead to the homogenous distribution of the HGMs.…”

This work deals with the development of flexible syntactic foams based on silicone and hollow glass microballoons (HGMs) for potential application as a lightweight thermal cum vapor barrier in fire-protective ensembles. HGMs offer excellent thermal insulation and their inclusion into silicone leads to significant weight reduction, while improving the level of protection. Flexible silicone foams containing different types and loadings of HGMs were prepared and it was observed that high-density microballoons (K46) survived compression molding process, due to their superior crushing strength (6000 psi) as compared to K15 (300 psi). The specific quasi-static mechanical properties increased proportionally to the extent of loading. The inclusion of HGMs did not alter the curing behavior of silicone resin. Syntactic foams (40% HGMs) were coated onto glass fabric (GF) to prepare composites and thermal protective performance tests were performed to establish their effect on heat transfer. The protection level was higher for syntactic foam containing K46 glass microballoons, as compared to K15. The second-degree burn time increased from 6.4 s (neat GF) to 10s for syntactic foam-coated GF. Our studies demonstrate the potential of the developed syntactic foam-coated GFs as a vapor cum thermal barrier in fire protective clothing.
