Problems solved by technology

[0002] At present, the known printing method is a method of transferring ink (consumables), and there are many ways, all of which are printing methods that transfer ink (consumables) to the surface of the printed object. The accuracy of printing depends on the printing method, and the durability depends on The degree of surface adhesion of the ink (consumables), once the ink on the surface of the printed object falls off or corrodes, the printing will fail. In some occasions that require moisture or water resistance, scratch resistance, high temperature resistance, and super weather resistance, ordinary printing methods and materials cannot meet these special requirements at the same time

Abstract

The present invention discloses one kind of nanometer material for direct no-contact laser printing without consumed printing material. The nanometer material consists of plastic or composite base material and mixed coloring agent and photocatalyst TiO2 in the amount of 0.02-10 wt% and average granularity of 0.05-3.00 micron. The present invention also discloses the direct no-contact laser printing method, which can form moisture-proof, scrape resisting, wear resisting and weather resisting permanent patterns and writing on the nanometer material. The direct laser printing is performed through controlling the laser lighting, and has the features of high speed, high precision, no printing material consumption, lasting printed patterns and writing. The present invention may be used widely in different industries.

Description

technical field [0001] The invention relates to a nano material suitable for direct laser irradiation printing, and also relates to a non-contact laser direct printing method using the material without printing consumables. Background technique [0002] At present, the known printing method is a method of transferring ink (consumables), and there are many ways, all of which are printing methods that transfer ink (consumables) to the surface of the printed object. The accuracy of printing depends on the printing method, and the durability depends on The degree of surface adhesion of the ink (consumables), once the ink on the surface of the printed object falls off or corrodes, the printing will fail. In some occasions that require moisture or water resistance, scratch resistance, high temperature resistance, and super weather resistance, ordinary printing methods And materials cannot meet these special requirements at the same time. Contents of the invention [0003] The p...
