Problems solved by technology

The accuracy of ceramic wine bottle mouth, especially the dimension accuracy of the outer mouth is low, resulting in poor matching accuracy with hard plastic and metal bottle caps with high precision requirements, and it is difficult to meet the anti-counterfeiting requirements through bottle caps, so it has become a major problem in the anti-counterfeiting of high-end liquor

Embodiment 1

[0021] Embodiment 1: According to the required bottle mouth molding (such as full thread), the corresponding bottle mouth pressure injection steel mold is manufactured, and the prepared ceramic raw material (sintering temperature is higher than the bottle body 20 ℃) ​​is processed into fine powder by dry ball milling, and the powder is added. 10wt% paraffin wax is used as the material, and the ceramic raw material fine powder and paraffin wax are fully mixed in a mixer at about 80°C to obtain hot-pressed grouting molding raw materials. The semi-finished molded bottle mouth molded body is obtained by hot pressing grouting method. The molded semi-finished product is buried in alumina fine powder and the paraffin is burned out in a kiln at 800°C to obtain a paraffin-free molded semi-finished product, which is then sintered in a kiln at 1190°C.

[0022] The sintered bottle mouth and the dry bottle body formed by grouting are bonded together with glaze water binder (melting point t...

Embodiment 2

[0023] Example 2: Same as Example 1, wherein the ceramic wine bottle is a sintered bottle body after grouting molding, that is, the bottle mouth and the bottle body are both sintered, bonded, and sintered again, and the final size of the bottle mouth deviates from the design size by +0.08 mm.

Abstract

The invention improves preparation method of ceramic wine-bottle and is characterized in that at least molding of the bottleneck is steel mold hot-press paraffin wax casting molding, after sintering the molded bottleneck, and cementing with a sintered or unsintered bottle body. The invention breaks through the technical problems that the precision of bottleneck of ceramic wine-bottle is low and the difficulty in solving bottleneck shaping limit; the requirement that ceramic wine-bottles have precise bottleneck dimension and diverse shaping variation like glass wine-bottles is realized; the uniformity of outer caliber dimension of the bottlenecks is high; the common difference of inner diameter and outer diameter can be less than or equal to 0.1mm; the yield, compared with the prior art, can be enhanced by at least 3%; the mold loss can be greatly reduced; the economic benefit is very obvious; the high requirements of wine market on sealing, opening, anti-counterfeiting of the wine-bottles can be completely satisfied; and matched use range of novel anti-counterfeiting bottle caps is widened, and irregular bottle caps such as full screw, fine screw and the like can be obtained, thusbeing applicable to ceramic wine-bottles, and initiating steel mold hot-press paraffin wax casting molding technique and sintering technique for at least the bottlenecks of ceramic wine-bottles.

Description

technical field [0001] The invention is an improvement to the preparation method of the ceramic wine bottle, and in particular relates to a preparation method of the ceramic wine bottle with high bottle mouth size precision and diversified outer bottle mouth shapes. Background technique [0002] Ceramic wine bottles have unique advantages, such as the function of aging and the diversity of appearance decoration. The dual-purpose function has gradually replaced the glass wine bottle, and has become the main container for dispensing wine. More and more attention has been paid to the packaging of wine, especially liquor. A large number of famous wines use ceramic wine bottles as containers. [0003] Ceramic wine bottle production, the prior art mainly adopts the grouting molding method, mainly contains three kinds: the first method: bottle body, bottleneck are formed by one-time grouting of same pair of moulds. However, due to the shrinkage rate from the semi-finished product ...
