The TGA-FTIR technique has been utilized to study the thermal degradation of poly (acrylic ester) (PAE) and its graphite oxide micro-and nano-composites. Nanocomposite formation is shown by the use of X-ray diffraction and transmission electron microscopy. The influence of graphite oxide on the degradation is followed and cone calorimetry has also been used to ascertain the role of graphite oxide in flame retardancy. 172

“…For this type of solid waste, one study has shown that its overall degradation rate in the soil is less than 1% every six months . Studies have also shown that this kind of solid waste is not suitable for the preparation of activated carbon due to its low cross-linking degree (the dosage of cross-linking agent is usually 1–5 wt % of total monomer mass), − which can be attributed to the fact that, during the pyrolysis process, more than 90% of its weight will be converted to volatile substances with high VOC content and complex components (usually containing the N element). , As a result, the widely adopted methods of disposing of PLSW by incineration or burial will inevitably cause secondary pollution and a large number of organic carbon sources and bring a heavy burden for enterprises and environment . Therefore, how to realize the green resource utilization of PLSW and avoid its secondary pollution are great challenges to the sustainable production and application of water-based coatings and inks.…”

It is a great challenge to sustainably produce and apply water-based coatings and inks in terms of realizing the green resource utilization of polyacrylate latex solid waste (PLSW) and avoid its secondary pollution. In this paper, a kind of high value-added amphoteric ion-exchange resin (AIER) was prepared by using diethylenetriamine to amidate PLSW under the optimized conditions from a Box-Behnken design. Its adsorption and regeneration properties and the universality of the method were investigated. The results suggested that AIER possessed a high removal efficiency to anionic dyes, and the batch dye adsorption processes were endothermic and spontaneous, which is consistent with a pseudo-second-order kinetic model. The penetration adsorption capacities of AIER were recorded to be 987.08 mg/g for RR239 and 1037.75 mg/g for RB5 at the optimized operating conditions of column height = 6.4 cm, flow rate = 1 mL/min, and dye solution of 500 mg/L. They were more than 200 times larger than that of commercial activated carbon when the mixture composed of AIER particle and diatomite particle (filter aid agent) was used as a fixed-bed adsorbent. Zeta potential analysis results indicated that the good adsorption and regeneration performances of AIER were mainly attributed to the presence of amino and carboxyl groups in the molecular structure of AIER. Most importantly, this method possessed excellent practicability and universality for different types of PLSW from factory wastewater. The results provide a feasible method and theoretical basis for the green resource utilization of PLSW, and the goal of “waste control by waste” was fundamentally achieved.
