Abstract

The invention provides a high hardness wear-resistant fingerprint-proof nano coating for a PC material and a preparation method of the high hardness wear-resistant fingerprint-proof nano coating. Theraw materials formula of the high hardness wear-resistant fingerprint-proof nano coating is prepared from the following components in parts by weight: 20-30 parts of matrix resin, 8-10 parts of a high-functional monomer, 3-5 parts of a low-functional monomer, 2-3 parts of a fluorine-containing functional monomer, 0.5-1.5 parts of an inorganic filler, 2-3 parts of an auxiliary agent, 1-3 parts of aphotoinitiator and 1-3 parts of a composite solvent. The matrix resin is a mixture of at least three polyurethane acrylates with different degrees of functionality, and respectively selected from 6-9functional, 9-10 and 10-15 functional aliphatic polyurethane acrylates; the high-functional monomer is 6 functional dipentaerythritol hexaacrylate, the low-functional monomer is one or two of 2 functional and 3 functional acrylate monomers; and the inorganic filler is nano-diamond particles. According to the high hardness wear-resistant fingerprint-proof nano coating, the preparation process is simple and efficient, mass production is convenient, the prepared coating is high in hardness, wear-resistant, fingerprint-proof, good in weather resistance and long in service life, and has good application prospects in the fields of automobiles and mobile phones.

Description

technical field [0001] The invention relates to the technical field of hardened coatings made of PC, in particular to a high-hardness, wear-resistant and anti-fingerprint nano-coating applicable to PCs and a preparation method thereof. Background technique [0002] PC is an engineering plastic processed with polycarbonate as the main component. It has the characteristics of high transparency, light weight, impact resistance, and aging resistance. Glass material greatly reduces product cost. However, the material's surface hardness is extremely low, it is easy to scratch, and it is easy to get fingerprints, which limits its application in the fields of automobiles and mobile phones. [0003] At present, PC material is used by more and more manufacturers in the control panels of automobiles and mobile phone display screens, so its surface hardening has become the key to its wide application. At present, most of the coatings are applied on the surface of PC by thermal curing ...
