Description
Technical Field
The invention relates to the technical field of plastics, in particular to a modified plastic prepared from waste plastics.
Background
The modified plastic belongs to an intermediate product in a petrochemical industry chain, is mainly processed by taking five general plastics and five engineering plastics as plastic matrixes, and has the characteristics of flame retardance, impact resistance, high toughness, easiness in processing and the like. The modified plastic is a plastic product which is processed by filling, blending, reinforcing and other methods on the basis of general plastics and engineering plastics and improves the flame retardance, the strength, the impact resistance, the toughness and other properties.
The polycarbonate plastic products are widely applied in life, great convenience is brought to the life of people, but the pollution of waste plastics to the environment also exists, and people also pay more and more attention to the recycling of the waste plastic products along with the gradual enhancement of the environmental protection consciousness. The patent application No. 200710138324.1 provides a method for recycling polycarbonate resin waste, and although the recycling of polycarbonate reclaimed materials is realized, the comprehensive performance of the prepared polycarbonate product is not improved. The patent with the application number of 201410031840.4 provides a polycarbonate composite plastic and a preparation method thereof, polycarbonate is used as a main raw material, and different types of resins are added for modification, so that the modified plastic with higher tensile strength and elongation at break is obtained, but the recycling of polycarbonate waste cannot be realized. At present, the process of modifying the plastic by polycarbonate waste is still immature, so that the common polycarbonate blending modified plastic on the market has insufficient performance. Accordingly, the present invention provides a modified plastic prepared from waste plastics to solve the problems set forth in the above background art.
Disclosure of Invention
