“…Aluminum hydroxide (ATH), as a class of inorganic halogen-free flame retardants, is commonly applied in flame-retarding polymer materials because of its low toxicity, cost benefit, good smoke suppression effects, environment-friendliness and widespread origin. As a result, the ATH has been increasingly applied in flameretardant polypropylene (PP) materials [1][2][3][4][5]. Up to now, all the flame-retardant PP materials mainly form a-crystal due to the a-nucleation on the surface of AHT on the PP crystallization.…”

In order to provide aluminum hydroxide with bnucleating surface (b-ATH) for PP crystallization, the calcium pimelate supported on the surface of ATH was prepared through chemical reaction between calcified ATH and pimelic acid in our lab. The b-ATH particles were characterized by Fourier transform infrared spectrometry, X-ray photoelectron spectroscopy and scanning electron microscopy. Effect of ATH, calcified ATH, and b-ATH on crystallization and crystalline modification of PP was investigated by differential scanning calorimetry. The results indicated that the prepared b-ATH has higher heterogeneous nucleation than ATH and calcified ATH for PP crystallization. Addition of ATH and calcified ATH has no influence on the crystalline modification of PP. The b-ATH can induce the formation of b-crystal in the ATH-filled PP composites with b-crystal content of above 90%. The transformation of surface nucleation mechanism of ATH from anucleation into b-nucleation was investigated. The effects of b-ATH content, mass ratio of calcified ATH/ pimelic acid and concentration of calcium acetate solution in the preparation of calcified ATH on the heterogeneous nucleation and b-crystal content of b-ATHfilled PP composites were discussed. The mechanical performance of the prepared b-ATH-filled PP composites were also characterized. POLYM. COMPOS., 00:000-000,

“…The performance of PP can be boosted substantially via use of reinforcing fillers, such as talc and short glass fibers. Other properties, e.g., reduction in mould shrinkage, can be improved via addition of low cost non‐reinforcing fillers such as calcium carbonate …”

Composites containing 50% wt fly ash (sourced from the UK and South Africa) in polypropylene homopolymer (manufacturer stabilized for general purpose use) have been prepared by using batch and continuous methods. The effect of the following coupling agents were investigated on the photo-and thermal-decomposition of the composite materials: Lubrizol Solplus C800 (an unsaturated carboxylic acid), c-methacryloxypropyl trimethoxy silane (c-MPS), 1,3-phenylene dimaleimide (BMI), and maleic anhydride-grafted-polypropylene (m-PP). High melt, thermal-, and photo-stability was favored when the matrix was coupled to the filler surface by monomeric coupling agents that were expected to adsorb in a close packed layer on the fly ash surface. Further improvements were observed in cases where the coupling agent could also self-polymerize. m-PP did not lead to increased stability due to its low adsorption density on the fly ash surface. The relatively high water/acid soluble transition metal ion content of the UK sourced fly ash did not appear to affect stability under the test conditions employed in this study. The South African sourced fly ash had a higher level of quartz and mullite together with a high level of group 1 and 2 metals. The latter in particular may have led to debonding of the coupled interfacial region from the filler surface and possible adsorption of stabilizers on the pristine surface. This resulted in the South African fly ash generally possessing poorer resistance to oxidation than the UK fly ash. V C 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 39974.

“…Barium sulfate is often used as additive in coatings, plastics, and paper to improve their toughness and impact strength [27,28]. Thus, barium sulfate and D-3RNL were selected for synthesizing a conjugate–BaSO 4 hybrid to treat dye wastewater and the dye-BSD sludge produced during the treatment process may have the potential to be reused as colorant fill-in coating.…”

Abstract:A new sorbent material, barium sulfate-Direct Blending Yellow D-3RNL hybrid (BSD), was synthesized and characterized by various methods. Both the anionic dyes, Reactive Brilliant Red X-3B and Weak Acid Green GS were hardly adsorbed by the BSD material, while the sorption of Ethyl Violet (EV) and Victoria Blue B were extremely obvious. The sorption of cationic dyes obeyed the Langmuir isotherm model, which depended on the electric charge attraction. The saturation amount of EV adsorbed onto the BSD material approached to 39.36 mg/g. The sorption of EV changed little with pH from 3 to 12 while it increased with increasing levels of electrolyte. A dye wastewater sampled from Jinjiang Chemicals was treated, and the color removal rate was more than the COD removal rate. In addition, the cationic dye-BSD sludge was utilized as a colorant fill-in coating. The light stability and thermal stability of the colorant was measured and exhibited good features. This work provided a simple and eco-friendly method for dye wastewater treatment with recycling of waste.
