Abstract
The invention provides high-gloss scratch-resistant polycarbonate, and a preparation method and application thereof, and belongs to the technical field of new materials. The high-gloss scratch-resistant polycarbonate comprises the following components in parts by weight: 63.4-73.5 parts of polycarbonate (PC) resin, 5-7 parts of (methyl methacrylate-butadiene-styrene) MBS resin, 20-25 parts of a scratch-resistant agent, 1-3 parts of silicone powder, 0.2-0.6 part of an antioxidant and 0.3-1 part of a lubricant. According to the high-gloss scratch-resistant PC material provided by the invention,scratch resistance of the high-gloss scratch-resistant PC material is improved, and meanwhile, important performance such as glossiness, impact strength and the like are considered; the high-gloss scratch-resistant PC material has good and balanced mechanical performance, thermal performance and electrical performance, the melt viscosity is lower, and processing is easier. In addition, the preparation method of the high-gloss scratch-resistant PC is simple in preparation, high in operability and easy in implementation, large-scale industrial production can be realized by using a double-screw extruder in an existing mature technology, and a very wide application prospect is achieved in the spraying-free field.
Description
technical field [0001] The invention relates to the technical field of materials, in particular to a high-gloss anti-scratch polycarbonate and a preparation method and application thereof. Background technique [0002] Polycarbonate (PC) has been widely used because of its excellent mechanical properties, thermal stability, dimensional stability and surface gloss, and has developed into one of the most important engineering plastics. At present, plastic spray-free coating has become one of the development trends of the plastic industry due to its advantages of environmental protection and cost reduction, and spray-free PC is also used in it. However, its poor surface scratch resistance limits its application in this field. Generally, methods to increase surface hardness include modification, blending, and coating, among which filling modification is simpler and more economical. However, there are relatively few studies on this direction and it is easy to affect important pr...
