Abstract
Concern for the environment, both in term of limiting the use of finite resources and the need to manage waste disposal, one of the rising environment protection materials is wood plastic composites(WPC). The study investigates the feasibility of using recycle Nylon6, Poly(ethylene terephthalate) and wood flour to manufacture experimental composite specimens. The specimens were made through extrusion, pelletised and injection molding. By adding POE-g-MA as agent into PET/Nylon (60/40、50/50、40/60), and MBS as impact- resistant agent into PET/Nylon (60/40、50/50、40/60), then discuss mechanical properties of WPC under different thermal and humid aging, thermal and humid effect and accelerate weathering. After thermal and humid aging for 200 hours and then accelerate weathering for one month, the result showed that no matter add POE-g-MA or MBS in the WPC, its tensile strength, flexure strength and flexure modulus will lose the biggest amount in the 55℃/90RH%. After accelerate weathering for one month, the result showed a decreasing trend. Besides, the impact strength in the 55℃/90RH% will enhance because the moisture absorption of Nylon6 can make WPC become more tougher. When it comes to the effect in accelerate weathering, the mechanical properties will be changed, and during exposure to UV radiation and water spray, will cause the material fade. In the end, we discuss creep of the WPC on the influence of different thermal and humid effects.
