Problems solved by technology

For example, PC / PMMA alloy, which combines the excellent mechanical strength and high temperature resistance of PC, and the high gloss and scratch resistance of PMMA, is widely used in many industries such as automobiles and home appliances; Injection molding is easy to decompose small molecules, resulting in the occurrence of injection molding abnormalities such as water streaks, and severe stress cracking in low temperature environments, and is not resistant to corrosion by chemical solvents, which limits its application.
For example, in the PC / PETG alloy, PETG not only makes up for the shortcomings of PC's poor fluidity and easy stress cracking, but also solves the problem of PC's resistance to chemical solvents, and at the same time greatly reduces the cost of materials. However, due to the soft texture of PETG, it makes Insufficient rigidity of the alloy, low flexural modulus of elasticity, and high molding shrinkage rate limit its application range

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PC / PMMA / PETG ternary alloy material and a preparation method thereof. Background technique [0002] With the development of society, the application of polymer materials is becoming more and more extensive, and the amount of use is also increasing, and the resulting plastic waste is also increasing. The molecular structure of plastic resin materials is stable, and it is difficult to decompose naturally when discarded in nature, which seriously damages the ecological environment. Therefore, the recycling of plastic resin materials has increasingly received social attention. At present, the recycling of waste plastics is mostly based on the process of melting, extruding and granulating after simple sorting. This process relies too much on the purity of sorting, and the degradation of plastic resin materials will lead to large performance differences, resulting in the p...
