Problems solved by technology

The general metal printing plate includes a metal base layer and a printing composite layer set on the metal base layer. This kind of metal printing plate has the problem of insufficient hardness of the surface coating, and it is easy to be scratched by sharp objects during transportation, installation and post-maintenance. It will cause wear and tear due to scratches, which will affect the appearance and service life. For the replacement and installation of a single damaged surface, it is easy to cause unnecessary scratches on the surrounding parts, thereby increasing the cost of use.

Abstract

The invention relates to the field of preparation technology of paint with scratch-resistance and wear-resistance, and especially relates to nanometer ceramic paint for pre-painting of metal printing plates with rollers and a preparation method thereof. The paint comprises the following components in parts by weight: 70-80 parts of nanometer ceramic resin, 10-15 parts of a curing agent, 2-4 parts of a matting agent, 0.5-3 parts of a fluorocarbon surfactant, 25-35 parts of a solvent, and 1-5 parts of an additive. A special Si / O structure in the components has binding energy which reaches 101 kilocalorie / mol, a vitrescent three-dimensional net structure can be formed after high temperature roast during a later period, so that hardness of a paint film on the surface of a coating is equal to or higher than 6H; the paint film is not easy to scratch or wear, and has excellent incombustibility and insulating properties; application limitation of the prior printing decorative plates which are prepainted with rollers is broken, good compatibility to a fluorocarbon coating layer is formed, and the paint is suitable for coating metal base materials or base materials with the fluorocarbon coating layer.

Description

technical field [0001] The invention relates to the technical field of preparation of scratch-resistant and wear-resistant coatings, in particular to a pre-roller-coated nano-ceramic coating for metal printed plates and a preparation method thereof. Background technique [0002] In recent years, metal printed decorative panels have gradually been widely used in construction, transportation, and medical and health industries. This kind of metal printed decorative panels is an integrated thermal insulation board. It has a new installation method that can replace traditional wood and stone patterns, and is suitable for building interior decoration. , exterior wall decoration, airports, subways, shopping malls and other public areas. The general metal printing plate includes a metal base layer and a printing composite layer set on the metal base layer. This kind of metal printing plate has the problem of insufficient hardness of the surface coating, and it is easy to be scratche...
