AI Technical Summary

Problems solved by technology

Because the PC material will deform at high temperature, the coating cannot be baked at high temperature, and the coating dried at low temperature is generally not sufficiently cross-linked, so it is not resistant to water boiling and solvent scrubbing
At present, the adhesion and mirror effect of the existing PC mirror resins on the market are average, but they cannot meet the requirements of solvent resistance and water boiling resistance. When the ink is applied, the mirror coating is bitten off, resulting in wrinkles, swelling, and foaming. And other phenomena, which affect the application of PC mirror resin

Abstract

The invention discloses a solvent-resistant and water-resistant PC mirror resin and a preparation method thereof. The PC mirror resin comprises the following components in parts by weight: 10-15 parts of epoxy-modified acrylic resin, 60-second nitrocellulose 5-10 parts, 70-75 parts of organic solvent, 10-15 parts of aromatic amine curing agent and 1-2 parts of epoxy silane coupling agent; the preparation method of the PC mirror resin is: adding the organic solvent into the mixing tank , add nitrocellulose under stirring for 60 seconds until it is completely dissolved, then add epoxy silane coupling agent and epoxy modified acrylic resin, and disperse evenly. The aromatic amine curing agent can be added when it is used. The product of the invention has the advantages of solvent resistance and water boiling resistance, and at the same time has good silver powder arrangement effect, excellent mirror effect, coating ink does not bite the bottom, and does not damage the effect of the mirror surface of the bottom layer.

Description

technical field [0001] The invention relates to the technical field of mirror resins, in particular to a solvent-resistant and water-resistant PC mirror resin and a preparation method thereof. Background technique [0002] PC mirror resin is a special resin with a mirror-like effect for PC sheets. It is generally used with mirror silver paste. The front side is printed and the back side looks like a mirror. [0003] In recent years, with the renewal and upgrading of mobile phone application materials technology, composite materials have become more and more widely used, and there are higher requirements for coatings related to composite materials. Since the PC material will deform at high temperature, the coating cannot be baked at high temperature, and the coating dried at low temperature is generally not sufficiently cross-linked, so it is not resistant to water boiling and solvent scrubbing. At present, the adhesion and mirror effect of the existing PC mirror resins on t...
