Description
Technical field
The invention belongs to glass technology field, especially a kind of preparation method of Embossing glass and goods thereof.
Background technology
For traditional Embossing glass, its manufacture method producing solid grain on glass mainly contains three kinds of modes as described below:
One, be softening under glass being utilized high temperature, through die casting, slowly cool aftershaping, its shaping manufacturing cost is high, and quality is comparatively coarse;
Its two, be utilize diamond grains clash into (sandblasting) glass back (because diamond hardness is greater than glass), make glass back therefore produce concavo-convex engraving effect, but therefore plant the making of mode, glass is not only made to be nearly opaque cloudy surface shape, and glass back can be made to form hole, countless hole and shaggy powdered glass thing, affect the quality degree of processed glass, cause dealer in order to cover up the apparent flaws of its coarse shape, often can do secondary processing process in its surface, as the process of color sprayed surface material, but because making processed glass be close in opaque shape on the contrary like this, and lower its effect and expression range thereof, especially to minute surface, or gold, silver, copper, aluminium, nickel, the various metal performance such as chromium buckle layer, shade, during the effect such as reflective, also cannot reach,
Its three, be utilize hydrofluoric acid (Hydrofluoric acid, be called for short HF) directly to be overlayed on the back side of glass, use erosion damage glass back, and produce concave-convex effect accordingly; But because this hydrofluoric acid is one have aggressive and volatile hypertoxic liquid, not only easily cause destruction, the pollution of environment, user in use also must be quite careful, otherwise it is as easy as rolling off a log injured, especially this acid solution is poor to the corrosion efficiency of glass in the use of reality, and be not easy to control, process also quite complicated, therefore this etching mode is not for user adopt simultaneously;
Its Chinese patent of four, to be Authorization Notice No. be CN2714561Y, it discloses a kind of Embossing glass, and this Embossing glass is the synthetic adhesive layer by one deck of fitting on glass with concave convex texture.Because the intensity of synthetic adhesive layer is poor, when long-time use, easily there is metaboly in the lines on it; Further, synthetic adhesive layer also easily produces aetiolation under sunlight irradiates; Meanwhile, also easy because occurring fitting insecure between synthetic adhesive layer and glass and occurring that adhesive layer comes off or the phenomenon of projection from glass surface.
In addition, traditional Embossing glass, the lines on it mostly is macroscopic lines, and mainly for the purpose of ornamental, its decorative effect is limited, and, not there is other functional result.
Summary of the invention
The present invention aims to provide a kind of preparation method and goods thereof of Embossing glass, this preparation method is easy to operation, cost is lower, safety coefficient is also high, and the glassware obtained by this preparation method is had good, the long-time use of light transmission and still can keep as new advantage.
A preparation method for Embossing glass, comprises the following steps:
(1) glass substrate and the bottom die with pattern of indentations groove is got out;
(2) one deck thermoplastic macromolecule material layer is coated with at glass baseplate surface, and thermoplastic macromolecule material layer is heated, during the glass transition temperature of the temperature around thermoplastic macromolecule material layer higher than thermoplastic macromolecule material, die is adopted to impress thermoplastic macromolecule material layer;
(3) after in the pattern of indentations press-in thermoplastic macromolecule material layer bottom die, the temperature around reduction thermoplastic macromolecule material layer is to the glass transition temperature lower than thermoplastic macromolecule material;
(4) then, remove die, thermoplastic macromolecule material layer can be formed with die bottom the pattern of indentations of pattern of indentations groove complementation, obtain Embossing glass.
