Abstract

The invention discloses a high toughness PC/PMMA alloy material and a preparation method thereof. The alloy material is prepared from the following raw materials in parts by weight: 65-85 parts of PC,28-36 parts of PMMA, 3-12 parts of a toughening agent, 0.5-1 part of a lubricant, 1.5-3 parts of an antioxidant, 0.1-0.5 part of a compatibilizer, and 0.2-0.8 part of a UV stabilizer. The high toughness PC/PMMA alloy material is obtained by thoroughly mixing all the components in proportion, and then performing extrusion and granulation by a twin-screw extruder. The obtained PC/PMMA alloy material has the characteristics of high toughness, high hardness, scratch resistance, simple production process, and the like, and can be widely used in various electronic product outer shells such as mobile phones, television liquid crystal displays, and automobile instrument displays.

Description

technical field [0001] The invention belongs to the technical field of polymer processing, and in particular relates to a high-toughness PC / PMMA alloy material and a preparation method thereof. Background technique [0002] Polycarbonate (Polycarbonate, PC) has high impact strength and excellent mechanical, thermal, electrical and other comprehensive properties, and can be widely used in various electronic product casings such as mobile phones, TV LCD monitors, and automotive instrument displays. However, the current electrical housing products also have strict requirements on the surface of the material. Among them, the most difficult thing to meet is that the surface of the material must have a certain hardness and scratch resistance, that is, when the user wipes the product, it cannot be easily scratched. . In order to characterize the surface hardness of the material, the scratch-resistant surface hardness is generally measured by scratching the pencil hardness on the s...
