Problems solved by technology

However, the existing mirror ink is a mirror silver paste prepared by using ultra-thin electroplated aluminum paste. After being attached to the surface of the glass, there will be a large amount of diffuse reflection (that is, the common mirror effect defect "white fog") to make the mirror effect Deterioration, so it can only be used for decoration of small-sized surfaces;
[0004] At the same time, due to the low compatibility between the aluminum-silver paste in the ink and the epoxy resin, the arrangement of the aluminum foil is poor, which leads to poor metallic luster of the plated surface. Due to the above reasons, the surface effect of the glass mirror is not good after being made. , the yield of the product is low

Abstract

The invention relates to the technical field of mirror ink, and discloses high-temperature-resistant mirror ink. The high-temperature-resistant mirror ink is prepared from the following components: 10-20 parts by weight of epoxy resin, 1-2 parts by weight of a toughening agent, 20-50 parts by weight of nano-metal of which the particle size D100 is less than or equal to 200 nm, 30-50 parts by volume of a solvent, 0.1-0.3 part by volume of a leveling agent, 1-3 parts by volume of a defoaming agent, 0.25-1.5 parts by volume of a coupling agent, 0.1-0.5 part by volume of a wetting agent, 0.05-0.2 part by volume of an anti-settling agent, 2-10 parts by volume of a dispersant, 1-5 parts by volume of a curing agent, and 0.1-0.2 part by volume of an ultraviolet light absorber. The mirror ink prepared by using the formula can be matched with different mesh numbers of gauzes for silk-screen printing, the particle size of the used nano metal powder can reach the nano level, and the nano metal powder is uniformly dispersed into the epoxy resin through the dispersant, so that the surface problem that a 'rime fog' defect is formed due to diffuse reflection on the surface can be avoided.

Description

technical field [0001] The invention relates to the technical field of mirror inks, in particular to a high-temperature-resistant mirror ink and a preparation method thereof. Background technique [0002] At present, the glass mirror technology is mainly used to attach a mirror film layer on the outer surface of the glass to achieve a mirror effect. To meet the requirements of glass products in different scenarios. [0003] However, the manufacturing process of the existing glass electroplating mirror is relatively complicated, such as the mirror ink is plated on the glass surface through the electroplating process, but this process method needs to frequently monitor the change of the electroplating solution concentration in order to prevent the uneven color of the electroplating. The process is complicated and costly. The waste water that this technological method brings is more can cause serious pollution problem. In order to overcome the above problems, most existing gl...
