Abstract

The invention discloses a multi-layered internal spray molding method for the glazed surface of a cosmetic glass bottle and the glass bottle thereof. The molding method includes raw material preparation: the raw materials used in the method are proportioned according to the following weight percentages: 60-79% lead-free glaze frit, 5-30% inorganic pigment, 15-25% Pine oil, 1‑8% cellulose resin. The invention can solve the technical problem of how to spray glaze on the inner wall of the glass bottle to form a glazed surface and improve the compatibility between the bottle body and the contents.

Description

technical field [0001] The invention relates to a surface treatment of glass using at least two coatings of different components, in particular to an internal spray molding method for spraying ink on the inner wall of a cosmetic glass bottle and sintering to form a glazed surface. The present invention also relates to a glass bottle prepared by the above method. Background technique [0002] Cosmetic bottles are generally made of plastic or glass, which material is determined according to the actual use. In order to make the cosmetic bottle have a good visual effect and user experience, and to ensure the compatibility of the bottle body and the contents, the current process mainly adopts the combination mode of low-temperature internal spraying and plastic liner. This mode will not last for a long time. Stablize. If it only needs to have a good visual effect and user experience, the current process mainly adopts the mode of spraying ink on the outer wall of the glass and t...
