Abstract

The utility model discloses a watchband which is made of a silica gel material, and a character pattern ink layer printed on at least one surface of the watchband is durable and wear-resisting, and difficultly falls off. The watchband comprises a baseband made of the silica gel material, a unit composite layer formed by a film and a character pattern ink layer printed on the film or a composite layer composed of a plurality of unit composite layers, and the composite layer is adhered or permeated on the surface of the baseband through a liquid vulcanization or solid vulcanization forming method in a manner that the character pattern ink layer is superposed between the inner surface of the film and the surface of the baseband. According to the utility model, the composite layer and the baseband are tightly combined together, so that the manufactured watchband is soft and has good tenacity; the character patterns printed on the watchband are durable and difficultly fall off; and furthermore, the character patterns can have the original luster and color for a long time under the protection of the film. The watchband provided by the utility model has the advantages that when the character patterns are printed on the film, large-scale printing can be adopted, so that cost is reduced, and time is saved.

Description

Watchband

Technical field

The utility model relates to the wrist-watch accessory, and particularly a kind of surface is printed on the silica gel watchband of durable wear character pattern.

Background technology

In the prior art; character pattern ink lay on the watchband all is the character pattern ink lay to be printed on the outer surface of watchband with silk-screen or water transfer printing method; and then in the coating (hereinafter referred to as protective layer) of described character pattern ink lay spraying thin layer; protect the character pattern ink lay that is imprinted on the watchband not come off with this; but because described protective layer; combination is not tight between ink lay and the watchband three; in wearing the process of wrist-watch; because watchband can often rub with cuff or clothes; protective layer on the watchband outer surface is easy to breakage; thus; the character pattern ink lay that causes being printed on the watchband outer surface comes off; thereby make watchband seem outmoded; greatly affect use value and the occupation rate of market of watchband product; in addition; in the prior art on the watchband printing of character pattern be on the watchband of having made, to print one by one; behind the ink setting of character pattern, apply one by one again protective layer; the method is not only time-consuming; effort; costly, and less very easy the coming off of the adhesion on dried character pattern printing ink and watchband surface.

Summary of the invention
