Research Significance Of Thermal Stability Of Wood Plastic Composite Materials
my country is a country with poor wood resources. The 8th forest resource survey results show that the forest coverage rate is only 21.63%, which is lower than the world average forest coverage level. In recent years The level is also insufficient, but the demand for wood products in the market is increasing, making my country import a large amount of wood each year to meet the demand for the domestic market. The various properties of wood plastic composite materials are similar to natural wood. The source of their raw materials is mainly wood, sawdust, wood powder, etc. The composite performance of wooden plastic composite materials produced by these raw materials is compared to wooden materials. The promotion and application of wooden plastic composite materials can not only replace some wooden materials, but also have significant economic, social and ecological benefits to my country.
The research of wood plastic composite materials is mainly concentrated in the aspects of physical performance, mechanical performance, and interface compatibility of increasing composite materials. In addition, the research of foaming WPC has also made certain progress, and there are fewer research on WPC thermal stability, and research on its oxidation induction time and oxidation inducement temperature is rare. WPC often aging, and plastic matrix is prone to heat oxidation, which directly affects the physical mechanical properties and thermal stability of the product, which will affect its use.
Therefore, in order to expand the application field of wood plastic products, it is significant to systematically study the thermal stability of wood plastic composite materials. The continuous deepening of this study can provide the necessary knowledge for the industrialization of wood plastic composite materials. At present, there are still gaps in the thermal stability test standards in the field of wood plastic composite materials, and plastic -related standards cannot objectively evaluate the thermal stability of wood plastic composite materials. Some scholars learn from plastic related standards to systematically explore the thermal stability of wood plastic composite materials, and summarize some of the existing research results related to WPC thermal stability. The thermal stability of WPC should attract the attention of people. The thermal stability research of wooden plastic composite materials can promote further breakthrough in the realization of technology and quality in my country, which is of great significance for the application field of wood plastic composite materials.
