In order to solve the problems of high preparation cost, poor toughness and heat resistance of polylactic acid (PLA) based wood-plastic composites, the biodegradable resin polybutylene succinate (PBS) with high flexibility and excellent heat resistance was selected as the modified resin. The environmentally friendly PBS-WF / PLA ternary degradable wood plastic composites were prepared by blending with Salix powder (WF) and polylactic acid (PLA). It gives full play to the performance compensation effect between the resin matrix, optimizes the performance and reduces the preparation cost.
Wood-plastic composites were prepared by compression molding. WF was modified by silane coupling agent KH550. PLA, PBS, stearic acid and modified WF were added to the two-roll mill with high and low roller temperatures of 180℃ and 170℃ in turn for uniform mixing. The mixed materials were cooled, chopped and paved into the mold cavity. After hot pressing and cold pressing, the sheet was obtained. The hot pressing temperature was 185℃, the pressure was 5 MPa, the time was 7 min, and the cold pressing pressure was 7 MPa, the time was 10 min. Finally, the mechanical properties, dynamic thermomechanical properties, heat resistance and thermal stability of PBS-WF/PLA composites were tested and analyzed, and the microstructure and interface bonding of the composites were observed by scanning electron microscopy.
From the analysis of mechanical and thermal properties, it can be seen that with the increase of PBS content in the resin system, the strength and rigidity of the composites decreased, and the static bending strength, elastic modulus, tensile strength, storage modulus and loss modulus decreased. However, the impact strength, Vicat softening temperature, thermal deformation temperature and the onset temperature of thermal decomposition in the second stage of thermogravimetric analysis increased, and the toughness, resistance to thermal deformation and thermal stability were improved. When the addition amount of PBS was 50 wt% of the total mass of the resin, the comprehensive properties of PBS-WF/PLA composites were relatively better. Compared with WF/PLA, the retention rates of static bending strength, elastic modulus and tensile strength of PBS-WF/PLA were 86.5%, 63.8% and 73.1%, respectively, and the impact strength increased by 40.1%. The vicat softening temperature, thermal deformation temperature and the initial temperature of the second stage of thermal decomposition of thermogravimetric analysis increased by 37.1℃, 53.7℃ and 4.1℃, respectively. The production cost is reduced by about 20 %. The microstructure analysis showed that when the amount of PBS was 30 wt%, it could be uniformly dispersed in the PLA matrix. The cross-section morphology of the composites was rough and the continuity was good. The interface of each component was well bonded, the phase separation phenomenon was not obvious, and the flexibility of the composites was improved. When the PBS content reached 50 wt%, the fracture surface of the composites appeared many holes and uneven, and the phase separation phenomenon appeared. The interfacial bonding ability became weak, which would lead to the decrease of mechanical properties.Conclusion: The prepared PBS-WF/PLA ternary degradable wood-plastic composites realized the performance compensation between PBS and PLA resin. The addition of PBS has a great influence on the mechanical and thermal properties of PBS-WF/PLA, and is closely related to the percentage content of PBS in the total mass of the resin. After the addition of PBS, the strength and modulus of PBS-WF/PLA composites decreased to varying degrees, but the toughness, heat resistance and thermal stability were significantly improved. Comprehensive analysis, when the addition amount of PBS is 50 wt%, the comprehensive performance of the composite material is relatively good and meets the requirements of conventional wood-based panels. At the same time, compared with WF/PLA composites, the preparation cost is reduced by about 20%. Dynamic thermomechanical properties and microstructure analysis show that PLA and PBS are thermodynamically incompatible systems. The addition of an appropriate amount (30 wt%) of PBS can achieve uniform dispersion in the PLA matrix, and the interface of each component is well bonded. When the content of PBS is too much (50 wt%), there are many holes and unevenness in the fracture surface of the composites, and the interfacial bonding ability becomes weak, which will lead to the decrease of mechanical properties.
