Hydration-active steel slag and slag micropowder were used as inorganic fillers with silane coupling agent (KH550) to prepare wheat straw/polyvinyl chloride wood-plastic composites (WPCs) by extrusion molding. A 35-day immersion and a pre-immersion test were carried out to analyze the influence of steel slag and slag micropowder on the physical and mechanical properties of the WPCs under wet conditions. Results showed the following: (1) KH-550 exhibited a good surface modification effect on the activated steel slag and slag micropowder, (2) an increase in the activated steel slag and slag micropowder content could effectively reduce the percent water absorption of the WPCs by 20% to 25% and the expansion by 20% to 24%, respectively, compared with the control group, but had a limited effect on the tensile strength retention, and (3) pre-immersion could effectively induce the synergistic reinforcement effect of the active fillers, resulting in reaching the saturated water absorption within 20 days. The water absorption and tensile strength were respectively 18% to 25% lower and 1.5% to 3% higher than those of the composites without pre-immersion. The results of this study could provide experimental data and theoretical references for the influence of hydration-active inorganic fillers on WPC properties.

We investigated the effects of amount of antioxidants variability on selected mechanical and physical properties of wood plastic composites. Recycled high density polyethylene (rHDPE) and natural fibers were compounded into pellets by compounder, then the pellets were extruded using co-rotating twin-screw extruder and test specimens were prepared by hot and cold press process. From the study, samples with 0.5 wt% of antioxidants produce the highest strength and elasticity of composites. The effect of antioxidants presence on water uptake is minimal.

This study evaluates the effects of densities and mixing ratio on the physical and mechanical properties of wood plastic composites boards at mixing ratio of 1:1 to 1:1.4 and nominal densities of 700kg/mm3 and 800kg/mm3. The quantity of High Density Polyethylene (HDPE) and saw dust used in the production of Wood Plastic Composites (WPCs) was weighed to a nominal density of 700kg/mm3 and 800kg/mm3. The materials were thoroughly mixed and fed into a neatly primed oil mould with a dimension of 300 x 300 x 10 mm. Test samples used for physical and mechanical properties determination were collected from each board produced from the mould. The results showed that WPCs board produced from mixing ratio 1:1 had the highest Modulus of Rupture (MOR) and Modulus of Elasticity (MOE) values of 6.52 mm N-2 and 564.95 mm N-2 respectively. Water absorption, thickness swelling and linear expansion of WPCs produced from wood/plastic ratio of 1:1.4 had the lowest mean values of 6.67, 0.83, 0.68% and 21.61, 1.33, 5.35% respectively after 2 hours and 24 hours of water immersion test. Analysis of variance carried out at 0.05% probability level showed that the effect of density and mixing ratio were significant on the physical and mechanical properties of wood plastic composites boards.
