Problems solved by technology

However, during the composite process of polymer organic materials and inorganic materials, there will be an interface between the two, and the size of the interface bonding force will have a greater impact on the composite material.
[0003] Typical example: Long glass fiber reinforced hot-melt polypropylene (PP) material is a light-weight, high-strength material widely used. It is the most suitable material for the automobile industry to replace steel, realize light weight, and save energy. However, the difference between long glass fiber and PP material If there is a bonding interface between the long glass fibers, the strength of the long glass fiber hot-melt polypropylene material will not meet the technical requirements, which will affect the use and sales of the product
Inorganic powder materials without organic coating treatment also exist in the form of aggregates in macromolecular organic materials, but due to the incompatibility between the particle surface and the matrix, there are obvious boundaries between the particle aggregates and the matrix, and even tiny voids When the material is brittle, the particles of the inorganic powder escape and easily form a cavity, and the filling of the inorganic powder without organic coating in the matrix is ​​uneven, which affects the product quality and appearance
