This study aimed to synthesize a high-value product, silicon carbide (SiC) whickers, using carbon black from recycled tires and waste silicon dioxide obtained from the photovoltaic industry via mechanical and thermal activation (IMTA) technology. Diverse whisker morphologies, including needle-like, nanowire-like, bamboo-like, and bead-like structures, were obtained. Furthermore, the effects of the synthesis parameters, such as the ball milling time, carbon‒silicon molar ratio, pyrolysis temperature, and pyrolysis time, on the quality of the SiC whiskers were investigated. The results showed that the carbon‒silicon ratio had the greatest impact on whisker formation, followed by the pyrolysis temperature, pyrolysis time, and ball-milling time. The purity of the synthesized silicon carbide whiskers was observed in the range of 42.63%-54.84%. Both the pyrolysis temperature and time improved the properties of the SiC. Additionally, the strength, hardness, abrasion resistance of the rubber and wear-resistant paint could be improved by adding less than 4% synthesized SiC whiskers, as confirmed via commercial product testing. The excellent performance of the synthesized SiC whiskers and the competitive market advantage of improving the product quality at a low economic cost were confirmed in this study.

“…Therefore, a better dispersion method is worth studying. Kychkin studied the effect of ultra-fine silicon carbide powder on the performance of epoxy resin [26]. The study found that when adding 0.75 wt % silicon carbide, a 16% increase in flexural strength and a 5% increase in compressive elastic modulus were observed.…”

SiC was modified by fluorine-containing organic substance 1H,1H,2H,2H-trifluoro-noctyltriethoxysilane (FAS) to change its hydrophilicity from hydrophilic to superhydrophobic nanoparticles, and the optimum conditions for hydrophobicity were effectively explored. Then, different content of fluorine-modified SiC (F–SiC) nanoparticles were added to the epoxy resin (EP) matrix to prepare composite coating samples. The results showed that the surface of SiC was modified by FAS to show superhydrophobicity, and the dispersion in EP was significantly improved. After adding F–SiC, the hydrophobicity, wear resistance and corrosion resistance of the coating were significantly improved. In addition, the corrosion resistance of the composite coating containing different contents of F–SiC was analyzed through electrochemical and salt spray tests. The results showed that the corrosion resistance of the coating was the best when the addition amount was 3 wt %. In general, the composite coating with 3 wt % F–SiC had the best overall performance. Compared with the EP coating, the water contact angle of 3 wt % F–SiC/EP composite coating was increased by 62.9%, the friction coefficient was reduced by 73.5%, and the corrosion current was reduced by three orders of magnitude. This study provides a new idea for the development of ultra-wear-resistant and anti-fouling heavy-duty coatings.

In this contribution, an epoxy resin based composites which synergistically modified by carbon fiber (MCF) and silicon carbide (SiC) particles were prepared. The chemical structure of MCF and SiC before and after surface treated using silane coupling agent were analyzed by Fourier transform infrared spectroscopy and X-ray diffraction, respectively. The mechanical properties including tensile, flexural, and compression of the composites were investigated. Moreover, the friction and wear performances were studied on a ball-on-ring wear tester. The results indicated that the best tensile, compressive, and friction and wear properties of composites were obtained when SiC particles content is 3.0 wt.%. Compared to the pure epoxy resin, when the SiC particles content is 4.0 wt.%, the best flexural strength and modulus were obtained, which increased by 8.7% and 52.97%, respectively. Both the average coefficient of friction (COF) and the wear mass losses of the composites decreased significantly with the addition of the modified SiC particles. In addition, the main wear mechanism of pure EP is adhesive and fatigue wear, while the SiC/MCF/EP composites exhibit abrasive and fatigue wear.
