Problems solved by technology

Talc powder filled PP composite materials have been widely used in the production of automotive parts and daily necessities. Compared with PP without talc powder, its products have good appearance quality, low shrinkage and higher heat distortion temperature. However, due to The affinity of the two-phase interface is not strong, and the direct filling of talc powder often leads to the decline of some mechanical properties, which limits the application of composite materials

Description

technical field [0001] The invention relates to a plastic film, in particular to a bionano plastic. Background technique [0002] As a general-purpose plastic, polypropylene has many excellent properties, but due to defects such as low mechanical strength, poor heat resistance, large shrinkage deformation, and poor creep resistance, its application, especially as a structural material, is greatly restricted. It cannot be used as a high-performance engineering plastic. Therefore, modifying polypropylene and engineering it has become an important research topic. [0003] Talc powder is a mineral composed of layered silicate crystals, PP filled with talc powder has good heat resistance, low shrinkage, good dimensional stability and high hardness. Talc powder filled PP composite materials have been widely used in the production of automotive parts and daily necessities. Compared with PP without talc powder, its products have good appearance quality, low shrinkage and higher he...
