Lettering method for cable polyurethane elastic body jacket

Abstract

The invention relates to a lettering method for a cable polyurethane elastic body jacket. The specific steps are as follows: (1) after a cable is extruded out of a jacket, the cable is air-dried; (2) the cable is put into an oven for preheating; (3) a lettering wheel is chosen and arranged on a lettering machine; (4) cyclohexanone solution and printing ink are mixed for spare use by the weight ratio of 1 to 20; (5) an angle formed by an ink-scratching piece and the lettering wheel is adjusted to 45 degrees, which is the best; (6) a front guide wheel and a rear guide wheel of the lettering machine are on the same straight line with a lettering pinch wheel; (7) after the pressure of the lettering pinch wheel is adjusted, lettering can be started; and (8) ink is added. The lettering method for a cable polyurethane elastic body jacket has the benefits that characters printed on the surface of the cable polyurethane elastic body jacket are bright-colored and clear, and problems such as double images can be avoided; and the characters cannot be easily erased out, so that the characters last for a long time.

Description

Technical field [0001] The invention relates to a printing method for a cable sheath, in particular to a printing method for a cable polyurethane elastomer sheath. Background technique [0002] With the development of the cable industry in my country in recent years, the application of new cable technologies and new materials has also been greatly improved, especially the application of polyurethane elastomers in cable sheathing materials. Polyurethane elastomer sheathing materials have low temperature resistance and wear resistance. , Good water resistance, environmental protection and other characteristics, is one of the best materials for processing special cables. However, the printing technology on the surface of the polyurethane sheath has always been a difficult problem in the cable industry. The printing fonts often appear watermarks, the fonts are blurred and deformed, and they are easily erased. [0003] This greatly limits the widespread use of such materials. Summary o...
