Abstract

The invention discloses a nanometer TiO2 / ZnO anti-ultraviolet coating for PC and a preparation method thereof. The anti-ultraviolet coating comprises 20 to 50 parts of polyester acrylate oligomer, 20 to 50 parts of active monomer, 2 to 4 parts of nanometer TiO2, 2 to 4 parts of nanometer ZnO, 1 to 10 parts of a photosensitizer and 0.5 to 1 part of a surfactant. After shaping, the coating provided by the invention has a good anti-ultraviolet function and certain transparency; and effective and firm bonding between nanometer TiO2 / ZnO and a coating substrate and between the coating and PC plastic are formed, so the coating hardly falls off.

Description

technical field

[0001] The invention relates to the field of modification and processing of polymer materials, in particular to a nano-TiO used for PC 2 / ZnO UV resistant coating and preparation method thereof. Background technique

[0002] Polycarbonate is the fastest growing general-purpose engineering plastic. It has high strength, good impact resistance, good fatigue resistance, good electrical properties, high transparency and free dyeing, and is non-toxic, harmless and tasteless, so it is widely used in glass assembly industry, automobile industry and electronic and electrical industry, etc. . However, its UV resistance is poor. Under the action of ultraviolet rays for a long time, the surface of the product will turn yellow, the size will change, the mechanical properties will decrease, and the service life will decrease. Therefore, it is very important to modify the UV resistance of PC materials.

[0003] The UV-resistant modification of PC has been deeply studie...
