Problems solved by technology

[0006] The present invention aims to overcome the problem of poor adhesion after the existing UV glue shrinks into raindrops, and provides a glass surface coated with metal refraction raindrops and its preparation process. The present invention makes the ring transparent by preparing an epoxy resin composition. The oxygen composition can not only shrink smoothly to form metal refraction raindrops, but also have strong adhesion ability, good scratch resistance and weather resistance, so that metal-like raindrops can be formed on the glass surface, which has a strong artistic decoration effect

Abstract

The invention relates to the technical field of glass production processes, and concretely relates to a glass coated with metal refraction raindrops on the surface, and a preparation process THEREOF. The glass coated with metal refraction raindrops on the surface comprises a glass plate, a transition layer is arranged on the glass plate, and metal refraction raindrops formed by shrinking and curing an epoxy composition are arranged on the transition layer. The epoxy composition is prepared from, by weight, 10 to 15 parts of brominated bisphenol A type epoxy resin, 8 to 12 parts of novolac epoxy resin, 5 to 10 parts of triphenylmethane triisocyanate, 7 to 12 parts of tetrafunctional epoxy resin, 8 to 15 parts of an organic solvent, 0.8 to 1.2 parts of a curing accelerator and 1 to 1.5 parts of a curing agent. By preparing the epoxy resin composition, the epoxy resin composition can be smoothly shrunk to form metal refraction raindrops, and the raindrops also have relatively strong adhesion ability and relatively good scratch resistance and weather resistance, so that metal-like raindrops are formed on the surface of glass, and a relatively strong artistic decoration effect is achieved.

Description

technical field [0001] The invention relates to the technical field of glass production technology, in particular to a glass whose surface is coated with metal refraction raindrops and a preparation process thereof. Background technique [0002] As we all know, glass is mostly transparent. In order to make the glass have a decorative effect, decorative lines are generally formed on the surface of the glass, but these lines are mostly geometric, linear or frosted. In nature, when raindrops fall on glass or lotus leaves, they will form crystal clear, three-dimensional small water droplets. The metal refraction raindrop is a special effect invented by simulating this natural phenomenon. Existing UV-materials such as coatings and inks with a large shrinkage rate can quickly shrink into the shape of raindrops under the condition of ultraviolet light irradiation, and the large volume shrinkage during the curing process will cause stress and defects that are difficult to eliminate...
