Problems solved by technology

The mirror coating material described in Patent Document 2 contains a bisphenol-type epoxy resin, an ammonia-containing curing agent that reacts with the bisphenol-type epoxy resin, and a silane coupling compound having reactivity or affinity for inorganic materials and organic materials. It has strong adhesion to the silver mirror film, copper film and the side of the glass substrate. However, because only bisphenol-type solid epoxy resin is used, it requires a long drying and curing time. In other words, it is not only quick-drying Poor, and the decoration resistance is not good, there is a problem of film whitening

Embodiment 1

[0085] The water-based mirror coating in Example 1 uses an acrylic silicone resin emulsion with a TG of 20.0° C. (manufactured by Asahi Kasei Chemicals Co., Ltd., product name Polyurex G623, non-volatile content is 46.0% by weight, prepared in water), and 70% is added to the water-based coating. The mirror is modulated with the amount of the total weight of the paint. The water-based mirror coating in Example 2 uses an acrylic silicone resin emulsion with a TG of 50.0° C. (manufactured by Toa Synthetic Chemical Co., Ltd., trade name シ-ラス PC100, the non-volatile content is adjusted to 46.0% by weight), and 70% is added to the water-based coating. The mirror is modulated with the amount of the total weight of the paint. The water-based mirror paint in Example 3 was used in an acrylic silicone resin emulsion (manufactured by Asahi Kasei Chemical Co., Ltd., trade name Polyurex G620, non-volatile content: 46.0% by weight) at a TG of 20.0°C, and 20% of a silane monomer was added.

Abstract

The invention provides an edge coating solution for a mirror, which comprises (A) a bisphenol-type liquid epoxy resin (having an epoxy equivalent of 150-300), (B) a bisphenol-type solid epoxy resin (having an epoxy equivalent of 450-3,300), (C) an o-cresol-novolak-type epoxy resin (having an epoxy equivalent of 180-300), (D) an epoxy curing agent, and (E) a silane coupling agent. The present invention relates to a water-based edge coating solution, which contains an acrylsilicone resin emulsion obtained by dispersing an acrylsilicone resin into water.

Description

technical field [0001] The invention relates to a mirror in which a silver mirror film, a metal protection film made of copper for silver mirror film protection, and a back protection film are sequentially laminated on a glass substrate; or a silver mirror film and a back protection film are sequentially laminated on a glass substrate In the mirror, in order to prevent the edge of the mirror exposed from the above-mentioned silver mirror film and metal protective film from being corroded, the edge paint for mirror is applied thereon and the mirror whose edge is coated with the edge paint for mirror. Background technique [0002] In the manufacture of mirrors, when coating the exposed edges of silver mirror films and copper films, it is known that the edges are chamfered and then coated with edge paint and dried. Usually, these coatings are carried out by hand in mirror factories or mirror processing factories. [0003] For example, Patent Document 1 discloses a traditional ...
