High-strength high-toughness glass fiber reinforced polypropylene material and preparation method thereof

Abstract

The invention relates to a high-strength high-toughness glass fiber reinforced polypropylene material and a preparation method thereof. The high-strength high-toughness glass fiber reinforced polypropylene material comprises polypropylene, an interface modifier A, an interface modifier B, glass fibers and a toughening agent. Through compounding of the toughening agent and the glass fibers, the toughness of the polypropylene material is greatly improved while ultrahigh tensile strength is maintained, the material performance basically exceeds the performance of long glass fiber reinforced PP, and the long glass fiber reinforced PP can be replaced with the material and the material can be widely applied to major industries such as automobiles and household appliances.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a high-strength and high-toughness glass fiber reinforced polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene material has a very wide application market. In addition to its strong plasticity and low price, it is also because polypropylene has different required properties after modification. Since the emergence of short glass fiber reinforced polypropylene technology, the technology for improving its performance has also been continuously developed, but it is difficult to overcome its bottleneck in the end. Therefore, on this basis, a technical solution of long glass fiber reinforced PP has been developed, which has greatly improved its performance. However, in the process of using long glass fiber, it faces the phenomenon of unstable processing, uneven dispersion and unstable performance. , Special treatment is required on the m...

Since the emergence of short glass fiber reinforced polypropylene technology, the technology for improving its performance has also been continuously developed, but it is difficult to overcome its bottleneck in the end

Therefore, on this basis, a technical solution of long glass fiber reinforced PP has been developed, which has greatly improved its performance. However, in the process of using long glass fiber, it faces the phenomenon of unstable processing, uneven dispersion and unstable performance. , special treatment is required on the mold structure. In addition, due to the influence of the production process of long glass fiber reinforced PP, the output cannot be greatly improved.
