Problems solved by technology

[0004] Aiming at the problem of heavy metals containing lead and cadmium in high-temperature ordinary decals, the market has developed corresponding low-lead high-temperature decals pigments to improve the pigment itself, try to replace or reduce the content of heavy metals containing lead and cadmium, but for now Low-lead high-temperature decal paper is dull in color and poor in appearance, and cannot meet the needs of customers

Embodiment 1

[0025] Embodiment 1: the decal method of anti-heavy metal precipitation, comprises the following steps:

[0026] S1: Raw materials: raw materials include the following components: feldspar 24g, quartz 45g, Datong soil 30g, white glaze 45g;

[0027] S2: Raw material processing: use various colored oxides and mineralizers as ingredients; Datong soil is calcined through a tunnel kiln at a calcination temperature of 1280°C; feldspar, quartz, calcined Datong soil and ingredients according to the ingredients: ball: water = 1:1.5:1 ball milling, sieving and drying the pigment after ball milling;

[0028] S3: Rolling black: blend the pigment and varnish according to the mass ratio of 10:7, and then grind to form the printed pigment;

[0029] S4: Screen printing: screen-print the printed pigments on the goose paper to make high-temperature decal paper, and apply a layer of organic adhesive on the surface of the high-temperature decal paper;

[0030] S5: Transfer printing: transfer th...

Embodiment 2

[0044] Example 2 Compared with Comparative Example 1, the high-temperature decal paper made in Comparative Example 1 passed the surface heavy metal detection, but the color was dull. The main reason is that during the firing process of high-temperature decal paper, the firing time is relatively long, and the precipitation of heavy metals in high-temperature decal paper exceeds 45%, which makes the amount of heavy metal leaching out of high-temperature decal paper excessive, so that the color of high-temperature decal paper will change. Dimming, similar to existing low lead high temperature decals.

[0045]Example 2 Compared with Comparative Example 2, the high-temperature decal paper made in Comparative Example 2 failed to pass the detection of heavy metals on the surface, and the color was bright and bright. The main reason is that there is no cooling after firing, and the heavy metal precipitation time is short, so the amount of heavy metal dissolution is very small, making ...

Abstract

The invention relates to the technical field of printing decal, in particular to a decal method capable of preventing heavy metal from precipitating. The method includes the following steps of S1, raw material preparation; S2, raw material treatment; S3, black rolling; S4, silk-screen printing; S5, transfer printing; S6, high-temperature treatment; S7, cooling; S8, spraying; S9, cleaning and S10, adding of a cover layer. According to the scheme, the color of high-temperature decal paper can be kept to be fresh and bright; and meanwhile the mode of additionally printing the high-temperature isolation cover layer on the surface of the high-temperature decal paper is adopted so that detection can be performed smoothly.

Description

technical field [0001] The invention relates to the technical field of printing decals, in particular to a decal method for preventing heavy metal precipitation. Background technique [0002] Wine bottles are containers used to hold wine. There are various styles of wine bottles, such as glass wine bottles, ceramic wine bottles, etc. Among them, ceramic wine bottles have a gorgeous appearance, and ceramic wine bottles can also be used as exhibits. Therefore, they are welcomed by people. Some decals are printed on the surface of existing wine bottles to mark the manufacturer or trademark of the wine bottle, so that consumers can know the relevant information of the wine bottle, and the color decals are used to print the wine bottle. The aesthetics of the bottle will also be greatly improved , After drinking the wine in the bottle, it can also be displayed as a work of art. [0003] At present, decals are used on wine bottles, and high-temperature decals, over-glaze decals, a...
