PMMA COMPOSITE MATERIAL, CO-EXTRUSION MOLDED PLASTIC PRODUCT AND PLASTIC PRODUCT

摘要

The present invention relates to the field of plastics technology, and provides a PMMA composite material comprising the following components by mass percentages: PMMA 50%-95%, a toughening agent 4%-50%, and a polycyclobutylene terephthalate 0.1-20%. The present invention also provides the co-extrusion molded plastic products from the above-mentioned PMMA composite material. The present invention provides the plastic products from the above-mentioned PMMA composite material as well. The addition of polycyclobutylene terephthalate into PMMA increases flowability, and the addition of the toughening agent therein enhances the impact resistance and toughness, both of which do not influence the original excellent properties of PMMA, thereby improving the physical properties of PMMA, further expanding the range of use, and producing co-extrusion molded products having a uniform thickness.
