Problems solved by technology

The unsafe hidden dangers of ordinary glass have greatly limited its scope of use.
Tempered glass is more and more popular in the market due to its high strength, good heat resistance stability, and high safety factor. However, tempered glass is expensive and cannot be used repeatedly, which limits its development speed to a certain extent.
At present, most of the coatings used for glass decorative panels are single-component coatings, baking coatings and two-component coatings. Due to their slow drying speed, low production efficiency, large area occupation, and large amounts of solvents, high pollution and high energy consumption ; UV coating is an environmentally friendly green coating without volatile organic compounds, which has the advantages of fast curing speed, low energy consumption, low equipment investment, and good paint film performance; Glass decorative panels, this product uses two-component epoxy series resin varnish as the adhesion primer for glass, and then uses screen printing digital inkjet ink, this product solves the problem of UV coating on glass, which is a dense and hard material. Adhesion problem, but two-component epoxy resin curing speed is slow, production efficiency is low, construction is difficult, and the digital printing pattern is single, and the decoration is poor

Abstract

The invention relates to a novel safety glass decorative sheet and a preparation method thereof. The novel safety glass decorative sheet is characterized in that a layer of ultraviolet curing adhesive primer is coated to a common glass surface; a layer of ultraviolet curing adhesive under film is coated to the surface of the coating of the ultraviolet curing adhesive primer; a layer of ultraviolet curing transfer film is transferred to the surface of the coating of the ultraviolet curing adhesive under film; a layer of ultraviolet curing adhesive above film is coated to the surface of the ultraviolet curing transfer film; a layer of ultraviolet curing protective finishing paint is coated to the surface of the coating of the ultraviolet curing adhesive above film. The novel safety glass decorative sheet provided by the invention has the advantages that the required production site is small, the equipment investment is low, the production efficiency is high, the energy consumption is low, and no pollution is generated, can reach the strength of tempered glass, and good in weather fastness of the coatings, high in heat stability, rich in color and pattern, full in film, high in hardness, capable of resisting scratches, easy to clean, and non-inflammable; compared with traditional commonly used tempered glass decorative sheets, the novel safety glass decorative sheet has a better decorative effect and protection function.

Description

technical field [0001] The invention belongs to the field of decorative panels for building materials, and in particular relates to a novel safety glass decorative panel produced by coating the surface with an ultraviolet curing coating (UV coating for short) and a preparation method thereof. Background technique [0002] With the development of the construction industry and people's higher and higher requirements for the living space environment, glass is more and more widely used in the fields of doors, windows, curtain walls and interior decoration. The unsafe hidden danger of ordinary glass has greatly limited its scope of application. Tempered glass is more and more popular in the market due to its high strength, good heat resistance stability, and high safety factor. However, tempered glass is expensive and cannot be repeatedly processed and used, which limits its development speed to a certain extent. At present, most of the coatings used for glass decorative panels ...
