Glass fiber reinforced polycarbonate material and preparation method thereof

Abstract

The invention discloses a glass fiber reinforced polycarbonate material and a preparation method thereof. The glass fiber reinforced polycarbonate material comprises the components by weight percent: 14-88.4% of polycarbonate, 5-30% of glass fiber, 3-25% of polyester, 1-8% of MBS toughening agent, 0.5-6% of talcum powder, 1-8% of grafting polyester, 1-7% of compatilizer and 0.1-2% of processing agent. Compared with the prior art, the glass fiber reinforced polycarbonate material has good surface appearance, better mechanical property as well as especially better rigidity and impact toughness and higher heat distortion temperature, thus having good application prospect in the field such as home appliances, automobiles, etc.

Description

[technical field] [0001] The invention relates to the technical field of polymer materials, in particular to a glass fiber reinforced polycarbonate material and a preparation method thereof. [Background technique] [0002] Polycarbonate is an important variety of general engineering plastics, with excellent comprehensive properties, high impact strength and good transparency, and can maintain high mechanical strength, good electrical properties, high Due to its dimensional stability and good molding performance, its application fields are also expanding, and it is currently used in various applications such as home appliances, automotive materials, and OA fields. [0003] Polycarbonate can be divided into aliphatic polycarbonate, alicyclic polycarbonate and aromatic polycarbonate according to different molecular structures, but so far, only bisphenol A aromatic polycarbonate has been industrialized Production, therefore, unless otherwise specified, polycarbonate on engineer...

Problems solved by technology

However, the mechanical properties of glass fiber reinforced PC / PBT materials are greatly reduced compared with glass fiber reinforced PC materials, especially in terms of material rigidity and heat resistance temperature; replace them with mineral fiber reinforced PC materials Glass fiber reinforced PC materials, such as silicon whiskers, greatly reduce the toughness and heat resistance of the material, and have no obvious effect on rigidity. For example, sericite and basalt fibers are used, although they are relatively strong in strength. There is not much difference between glass fiber reinforced PC, but the degree of "ugliness" on the surface is also almost the same as that of floating fiber
