Problems solved by technology

In order to meet the diverse needs of people, researchers have gradually developed decal paper paint bottles that are coated with paint on transparent bottles and pasted with decals. In this study, borrowing the existing technology of pasting decals on transparent bottles will cause paint The problem of falling and not sticking the decal paper tightly, therefore, it is necessary to develop a new manufacturing technology corresponding to the decal paper paint bottle

Embodiment 1

[0016] A method for spraying and decorating glass bottles, comprising:

[0017] Wash the glass bottle with water containing 2% hydrofluoric acid, and treat the outer surface of the glass bottle;

[0018] spraying paint on the outer surface of the glass bottle;

[0019] Baking the painted glass bottles in an oven at 150-190°C for the first time;

[0020] Cool down to 70-80°C;

[0021] Soak the flower paper to be pasted in warm water;

[0022] At room temperature, paste the soaked flower paper on the outer surface of the cooled glass bottle and let it dry naturally;

[0023] Put the glass bottle into an oven at 160-180° C. for the second baking to obtain a painted and baked glass bottle.

[0024] Washing the glass bottle with water containing 2% hydrofluoric acid by mass can improve the problem of poor tinting strength of the bottle, and the first baking of the glass bottle after spraying paint at 150-190 ° C can improve the tinting strength of the bottle and prevent the bot...

Embodiment 2

[0026] In the present embodiment, the flow process of glass bottle spray color decal method is, as figure 1 , as shown in:

[0027] Step 101, removing the stains on the outer surface of the glass bottle;

[0028] Removing stains can improve the adhesion between glass bottles and paint, and improve the uniformity of painting.

[0029] Usually, for the convenience of observation, the inner surface of the glass bottle should also be kept as clean as possible.

[0030] Step 102, clean the glass bottle with water containing 2% hydrofluoric acid by mass;

[0031] Hydrofluoric acid is a weak acid that can react with alkaline substances on the surface of the glass bottle and change the acidity and alkalinity of the surface of the glass bottle, thereby providing a prerequisite for stronger adhesion between the paint and the outer surface of the glass bottle during subsequent painting. Among them, 2% is a relatively strict control condition. At this mass percentage concentration, aci...

Abstract

The invention relates to the field of material processing and in particular relates to a glass bottle colour spraying and decoration firing method. The glass bottle colour spraying and decoration firing method comprises the following steps of: treating the outer surface of a glass bottle by cleaning the glass bottle with water containing 2% of hydrofluoric acid; spraying oil paint onto the outer surface of the glass bottle; carrying out primary baking on the glass bottle sprayed with the oil paint in an oven at the temperature of 150-190 DEG C; cooling to 70-80 DEG C; soaking a piece of decoration paper to be pasted in warm water; at room temperature, pasting the soaked decoration paper onto the outer surface of the glass bottle after being cooled, and naturally airing; and placing the glass bottle into an oven at the temperature of 160-180 DEG C, and carrying out secondary baking so as to obtain an oil-paint-sprayed and decoration-fired glass bottle. By adopting the glass bottle colour spraying and decoration firing method, oil paint can be coated outside a transparent glass bottle and then the decoration paper is baked, and adhesive strengths of the oil paint and decoration paper are greatly enhanced.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a color-spraying and embossing method for glass bottles. Background technique [0002] Bottles with decal paper are very popular, but the related technology of making decal paper bottles still stays at decal paper on transparent glass bottles, adjust the temperature at about 560 degrees, and paste the decal paper on the On a clear glass bottle. Among them, 560 degrees can solve the problem that the decal paper is not pasted when the decal paper is pasted on the transparent glass bottle, and the decal paper is incomplete. In order to meet the diverse needs of people, researchers have gradually developed decal paper paint bottles that are coated with paint on transparent bottles and pasted with decals. In this study, borrowing the existing technology of pasting decals on transparent bottles will cause paint The problem of falling and not sticking the decal paper tightly, theref...
