Embodiment 1

[0034] A method for manufacturing spectacle frame plates, comprising the steps of:

[0035] (a) Prepare at least two raw material layers of spectacle frame plates, including preparing an upper protective layer, a middle pattern layer and a lower substrate layer; the upper protective layer is made of transparent or translucent cellulose diacetate rubber sheet; the pattern layer is made of silk The screen-printed pattern is covered on the surface of cellulose diacetate glue board; the lower substrate layer is made of cellulose diacetate glue board.

[0036] (b) Stack the raw material layer prepared in step (a): the upper protective layer, the middle pattern layer and the lower substrate layer in sequence in a closed mold, and heat the mold to 200°C under vacuum conditions. During the process, each raw material layer is melted into a liquid state, and the raw material layer forms a three-layer layered slurry.

[0037] (c) Place the mold processed in step (b) in the cooling machi...

Embodiment 2

[0042] A method for manufacturing spectacle frame plates, comprising the steps of:

[0043] (a) Prepare at least two raw material layers of spectacle frame plates, including preparing the first protective layer, the second pattern layer, the third pattern layer, the fourth reflective layer and the fifth substrate layer; the first protective layer is made of transparent or translucent Made of cellulose diacetate plastic sheet; the pattern layer is made by printing transparent or translucent patterns on sublimation paper by digital printers, and transferring the pattern to the surface of cellulose diacetate plastic sheet by heating the sublimation paper The pattern layer is made of cellulose diacetate rubber sheet with concave or convex or perforated patterns; the reflective layer is made of pearl flakes or pearl powder layer, or pearl powder is mixed with cellulose diacetate rubber sheet Made; the substrate layer is made of cellulose diacetate rubber sheet.

[0044] (b) The fi...

Embodiment 3

[0050] A method for manufacturing spectacle frame plates, comprising the steps of:

[0051] (a) Prepare at least two raw material layers of spectacle frame plates, including preparing an upper protective layer and a lower substrate layer; the upper protective layer is made of transparent or translucent cellulose diacetate rubber sheet; the lower substrate layer is made of metal ink pattern layer Made by printing set on the surface of cellulose diacetate glue board.

[0052] (b) The upper protective layer and the lower substrate layer prepared in step (a) are stacked sequentially from top to bottom in a closed mold, and the mold is heated to 180°C under vacuum conditions. During the heating process of the mold, Each raw material layer is melted into a liquid state, and the raw material layer forms a two-layer layered slurry.

[0053] (c) Place the mold processed in step (b) in the cooling machine, lower the temperature of the mold to 50°C, then take the mold out of the cooling...

Abstract

The invention relates to the technical field of glasses rack sheet material and especially relates to a manufacturing method of a glasses rack sheet material. The manufacturing method comprises the following steps: (1) preparing at least two layers of raw material of the glasses rack sheet material, wherein at lest one raw material layer has patterns; (b) piling the raw material layers prepared in the step (a) in an enclosed die successively and heating the die to 180-250 DEG C under vacuum condition to melt each raw material layer into liquid state and form layered slurry during heating of the die; (c) disposing the die treated in the step (b) into a refrigeration machine, cooling the die to 50-65 DEG C, taking out the die from the refrigeration machine for standing and cooling the die to a room temperature to coagulate each raw material layer into glasses rack sheet material; (d) cutting and processing the glasses rack sheet material prepared from the step (c). The manufacturing method of the present invention is simple, easily operated and with a short manufacturing period; the prepared glasses rack sheet material has intelligible pattern and wear resistance.

Description

technical field [0001] The invention belongs to the technical field of spectacle frame plates, and in particular relates to a manufacturing method of spectacle frame plates. Background technique [0002] Spectacle frames generally include spectacle frames and spectacle legs. Existing spectacle frames generally use surface treatment processes such as spraying and oiling to print aesthetic patterns and patterns on the surface of spectacle frames. This relatively primitive surface treatment process Clarity is low, and not wear-resistant. Application number is 200510034185.9 Chinese invention patent discloses a kind of spectacle accessories with silk screen printing pattern and its surface treatment process, spectacle accessories include spectacle frame, bridge of the nose, Zhuangtou and spectacle legs, described process comprises the following steps : Input the selected pattern into the computer, and typesetting the pattern; make the film and silk screen mold of the pattern fo...
