Research on Processing Technology Product Design and the Application of Nano-Wood-Plastic Composite Materials

This study focused on the design of wood-plastic composite (WPC) products. In this study, recycled high-density polyethylene plastic was used as the matrix, wood powder was used as the filler, different types of nanofillers and self-synthesized nanofiller treatment agents were added, and the twin-screw extrusion granulation method was used to prepare nano-WPC materials. The effects of different types of nanofillers on the mechanical properties of nano-WPC materials were investigated, and the cross-sectional structures of the materials were analyzed by scanning electron microscopy. The results showed that nanofiller treatment agents improved the interface compatibility of the materials. When the treatment agent content reached 2.5% and the nano-montmorillonite content reached 10%, the mechanical properties of the material reach their maximum values.

Properties Of Composites

The blend composite materials of bio-ethanol byproduct-Poly(lactic acid) (PLA) were produced by a twin-screw extrusion process. Effects of bio-ethanol byproduct (BEB) contents and different compatibilizers on properties of composite materials were investigated. The research showed that with the increase of contents of bio-ethanol byproduct, the mechanical properties decreased. The mechanical properties of composites were improved by adding the compatibilizers, especially the polypropylene grafted maleic anhydride (PP-MAH). When the PP-MAH content was 2.5%, the mechanical properties of the composite materials were superior to others.

In this study, cellulolytic enzyme lignin (CEL) was blended with polycaprolactone (PCL) by twin-screw extrusion and injection molding. The thermal, mechanical properties and the morphology of the PCL/CEL blends were investigated as a function of CEL content. The results showed that the CEL in the blends acting as nucleus accelerated the crystallization of PCL when CEL was not more than 10 wt%, but retarded PCL to crystallize with more CEL addition. Thermogravimetry analysis (TGA) revealed that the thermal stability of the PCL/CEL blends was almost unaffected by increasing CEL content. Mechanical test showed that, although the elongation at break and the impact strength were decreased, the strength and the modulus of the PCL/CEL blends were significantly higher than those of the neat PCL. Scanning electron microscopy (SEM) observations indicated that the CEL and the PCL were in good miscibility and there was a good adhesion at the interface of the CEL filler and the PCL matrix, suggesting that CEL could be potential filler used in PCL-based materials to reduce the cost of the friendly material, whereas increased its strength and modulus.

Mechanical properties of wood plastic composite, prepared from acrylate-styrene-acrylonitrile (ASA) and bagasse, were investigated. In this study, 10 to 50 phr of bagasse were used in order to obtain the wood plastic composite with superior mechanical properties. The wood plastic composites in the study were prepared by melt-blending technique. All materials were mixed by using a two-roll-mill, shaped into sheets by a compression molding machine and the specimens were cut with a cutting machine. Youngs modulus, flexural strength, flexural modulus, impact strength and hardness of the wood plastic composites were investigated and found to improve with increasing bagasse content. However, some composite properties, i.e., impact strength, was decreased by adding the bagasse and then become steady when the amount of bagasse added was more than 30 phr. It was concluded that wood plastic composites with the desirable mechanical properties can be formulated using ASA as the matrix polymer and 50 phr of bagasse.

Carbon nanoplatelet and nanoalumina reinforced PEEK nanocomposites were fabricated by twin-screw extrusion followed by injection molding. The effect of the filler loading on mechanical properties, morphology, dielectric strength, and thermal stability of the composites has been analyzed. The mechanical properties were found to increase with nanoplatelet content up to 1% loading (optimum filler content) and after that, due to agglomeration of filler, slight decrease in properties were observed. For alumina-filled systems mechanical properties increased with increasing filler content due to the well-dispersed fillers in the composites. The modulus and toughness of alumina-filled composites were higher than platelet-filled composites.

This paper describes a future-oriented approach for the valorization of polyethylene-based multilayer films. The method involves going from eco-design to mechanical recycling of multilayer films via forced assembly coextrusion. The originality of this study consists in limiting the number of constituents, reducing/controlling the thickness of the layers and avoiding the use of tie layers. The ultimate goal is to improve the manufacturing of new products from recycled multilayer materials by simplifying their recyclability. Within this framework, new structures were developed with two polymer systems: polyethylene/polypropylene and polyethylene/polystyrene, with nominal micro- and nanometric thicknesses. Hitherto, the effect of the multi-micro/nanolayer architecture as well as initial morphological and mechanical properties was evaluated. Several recycling processes were investigated, including steps such as: (i) grinding; (ii) monolayer cast film extrusion; or (iii) injection molding with or without an intermediate blending step by twin-screw extrusion. Subsequently, the induced morphological and mechanical properties were investigated depending on the recycling systems and the relationships between the chosen recycling processes or strategies, and structure and property control of the recycled systems was established accordingly. Based on the results obtained, a proof of concept was demonstrated with the eco-design of multi-micro/nanolayer films as a very promising solution for the industrial issues that arise with the valorization of recycled materials.

Nanocomposites are hybrid materials that can be obtained with, three, two or bust one-dimensional in nanoscale found in particles dispersed in the matrix. By presenting a nanometric structure, this new class of materials may have only properties, different from traditional composites and their constituents, which may be established in the synthesis process. The aim of this work is prepare nanocomposites of HDPE/ bentonite clay by melt intercalation technique. Systems were evaluated for the presence of untreated clay and chemically treated (organoclay) with two different types of quaternary ammonium salts, Cetremide and Dodigen. In the preparation of nanocomposites were obtained concentrated using a high speed mixer and then the nominal percentage of clay was dispersed in a twin screw extruder corrotacional. The systems were characterized by X-ray diffraction and mechanical properties. The XRD patterns of nanocomposite of HDPE/organoclay suggest a not intercalated structure. The mechanical properties of nanocomposites presented reducing values in relation to pure polymer.
