Embodiment 1
[0034] A manufacturing method of a spectacle frame plate, comprising the following steps:
[0035] (a) Preparation of raw material layers for at least two layers of spectacle frame plates, including preparation of 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 sheets; the pattern layer is made of silk The screen-printed pattern is made by covering the surface of the cellulose diacetate rubber sheet; the lower substrate layer is made of the cellulose diacetate rubber sheet.
[0036] (b) The raw material layer prepared in step (a): the upper protective layer, the middle pattern layer and the lower substrate layer are sequentially stacked in a closed mold, and the mold is heated to 200 ℃ 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 stratified slurry.

Embodiment 2
[0042] A manufacturing method of a spectacle frame plate, comprising the following steps:
[0043] (a) Preparation of raw material layers for at least two layers of spectacle frame plates, including preparation of a first protective layer, a second pattern layer, a third pattern layer, a fourth reflective layer and a fifth substrate layer; the first protective layer is made of transparent or translucent It is made of cellulose diacetate rubber sheet; the pattern layer is printed on the sublimation paper by a digital printer with transparent or translucent patterns, and the pattern is transferred to the surface of the cellulose acetate rubber sheet by heating the sublimation paper. ; The pattern layer is made of a cellulose acetate rubber sheet with a concave or convex or perforated pattern; the reflective layer is made of a pearlescent sheet or a pearlescent powder layer, or the pearlescent powder is mixed with the cellulose diacetate rubber sheet made; the substrate layer is ...
Embodiment 3
[0050] A manufacturing method of a spectacle frame plate, comprising the following steps:
[0051] (a) Preparation of raw material layers for at least two layers of eyeglass frame plates, including preparation of an upper protective layer and a lower substrate layer; the upper protective layer is made of a transparent or translucent cellulose diacetate rubber sheet; the lower substrate layer is made of a metal ink pattern layer Made by printing on the surface of a cellulose diacetate rubber sheet.
[0052] (b) The upper protective layer and the lower substrate layer obtained in step (a) are stacked in a closed mold from top to bottom, 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-layered slurry.
[0053] (c) Place the mold processed in step (b) in a cooling machine, reduce the temperature of the mold to 50°C, and then take the mold o...
