Recycled Hdpe

In this study, coal ash/recycled plastic composite material was fabricated with post-consumer high-density polyethylene (HDPE) and coal ash particles. The main idea of using coal ash, since it is also a waste product, as reinforcing filler in recycled HDPE is to reduce the cost, develop lightweight and produce environmental-friendly materials. Coal ash/recycled plastic composite have been used in significant applications as construction materials including flooring, landscaping, fencing, railing window framing and roof tiles. Effect of coal ash loading on the mechanical properties and thermal conductivity of coal ash/recycled HDPE composite were determined. It is expected to use waste materials in new field by getting novel composite materials with developed mechanical properties. It was found that coal ash filler indicated significant improvement on the mechanical properties of composites. The results show that the impact decreased tremendously from 57.32 to 15.8[Formula: see text]kJ/m2 with only 30[Formula: see text]wt.% loading of coal ash. The filler increases the elasticity of the material and reduces its ability to absorb deformation energy.

In order to improve the flame retardancy of wood-plastic composites,a new sandwiched composite is introduced in this paper with basic magnesium sulfated whisker(MOS) filled high density polyethylene(HDPE) as skin and wood flour filled HDPE as core.The oxygen index of the skin and the mechanical properties of the whole sandwiched composite are investigated. The results show that, the flame retardancy of the skin will be improved siginicantly when much MOS is used,and the skin containing 40wt% MOS has an oxygen index of 25.6%,in addition,the sandwiched composite in which both the mass contents of MOS in the skin and wood flour in the core are 40% has better mechanical properties than the traditional wood plastic composite(WPC) without any skin,and the sandwiched WPC is more fatigue-resistant.

In this paper, red phosphorous (RP) was coated by aluminum hydroxide to prepare modified RP (MRP). MPR was blended with high density polyethylene (HDPE) to obtain MRP/HDPE composites. And the properties of MRP/HDPE composites were investigated. The effects of MRP on the flame retardancy, thermal decomposition behavior and mechanical properties of HDPE were also discussed.

In recent years, Wood Plastic Composite (WPC) has found widespread applications in the field of construction, decoration and furniture. In this work, the effect of weathering on the mechanical properties of WPC made from high density polyethylene (HDPE) and rice straw particles (RS) has been studied. Different loading of composite (20, 35 and 50% RS) were tested. Polyethylene wax (PE-wax) and UV-stabilizer were also added to assess their effect on the WPC composite.

Abstract Chicken eggshell powder (ESP) as natural source of CaCO3 was incorporated as natural filler into High Density Polyethylene (HDPE).This natural source can be considered as an effective alternative for the commercial calcium carbonate (CC) filler. Characterization of ESP and CC was investigated by FTIR and XRD analysis. HDPE composites filled with 30 phr (ESP) and (CC) were prepared using internal mixer. 2 phr maleic anhydride (MA) was added as compatibilizing agent to HDPE/ESP composite. The prepared composites were vulcanized by using γ-radiation at doses from 50 to 150 kGy. Mechanical and flame retardancy properties of all composites were investigated; composites were thermally analyzed using TGA and DSC. The results showed that, the mechanical properties of HDPE decrease by incorporation of ESP or CC into it, as it was noticed that the mechanical properties of HDPE/ESP composite were better than the mechanical properties of HDPE/CC composite. Moreover, addition of MA led to improvement in mechanical properties of the HDPE/ESP composite. As well, the thermal stability and flame retardancy of the composites increased by adding ESP or CC to HDPE. The results were proved by scanning electron microscopy (SEM).

Sawdust/recycled high density polyethylene (rHDPE) composites were prepared and their mechanical properties, flammability and morphology were investigated. Sawdust was used at contents of 30, 40 and 50 wt%. With increasing sawdust content, tensile strength and elongation at break of the composites decreased whereas tensile modulus increased. Flexural properties showed the same trend as tensile properties. Flammability of the composites enhanced with increasing sawdust content. Mechanical properties of alkali treated sawdust/rHDPE composites were higher than those of untreated sawdust/rHDPE composites at all sawdust contents. Moreover, alkali treatment improved flame retardancy of the composites. SEM micrographs showed that alkali treatment enhanced the interfacial adhesion between sawdust and rHDPE matrix.
