Problems solved by technology

However, the surface of the fluoroplastic outer sheath is very smooth, the surface tension is small (only about 1 / 7 of the surface tension of the PVC outer sheath), and the adhesion is poor. Ink printing) method to print on the surface of the untreated fluoroplastic outer sheath, the adhesion fastness of the words is poor, the abrasion resistance is not good, it is easy to be wiped off, and it will cause trouble for the laying and use of the cable

Embodiment Construction

[0006] After the cable is extruded with a fluoroplastic outer sheath, the temperature reaches 360-400°C, and it is cooled and shaped by water in the heating device at a temperature of about 130°C under a pressure of 0.2Mpa. The length of the water tank in the heating device is about 1m, so that The surface temperature of the fluoroplastic outer sheath is still above 100°C after water cooling and shaping. Use a drier to dry the surface of the fluoroplastic outer sheath after the cable exits the water tank. After drying, use a plasma flame sprayer to treat the surface of the fluoroplastic outer sheath to make the surface rough, which can increase the surface tension and improve the adhesion. Then use the curved printing wheel to print on the surface of the plastic outer sheath, which can avoid the problem that the surface of the fluoroplastic outer sheath is deformed (from a circle to a flat shape) when the existing flat printing wheel is used to print. Then use another plasma ...

Abstract

The invention provides a method for printing words on the surface of a cable with a fluoroplastic sheath, which comprises the following steps: performing water-cooling sizing after extruding the fluoroplastic sheath of the cable; performing surface drying; and printing words on the surface of the fluoroplastic sheath by adopting a type wheel. During water-cooling sizing, a heating device is adopted to maintain the water temperature about 130 DEG C under the pressure of 0.2MPa; after the surface of the fluoroplastic sheath is dried, the surface thereof is treated; a plasma flamethrower ionizes the air to generate a high-concentration plasma source, and plasmas are sprayed through compressed air to treat the surface of the fluoroplastic sheath, so that the surface is roughened; the arc type wheel is used to print words on the surface of the fluoroplastic sheath; and another plasma flamethrower dries the printed words. The method for printing the words on the surface of the cable with the fluoroplastic sheath can obviously improve the adhesion firmness of the printed words, so that the printed words have good scuff resistance and are difficult to erase, and the cable is convenient to lay and use.

Description

technical field [0001] The invention relates to a method for printing on the surface of a cable, in particular to a method for printing on the surface of a cable with a fluoroplastic outer sheath. Background technique [0002] Fluoroplastics have good electrical properties, small dielectric constant, wide operating temperature range, high thermal stability, good flame retardancy, good chemical corrosion resistance and mechanical properties, and good non-stick properties on the surface of fluoroplastics. and stain resistance. Therefore, fluoroplastics are more and more widely used to make outer sheaths of various cables. After the cable is made, it is necessary to print the cable model and cable length (meter mark) on the surface of the cable to facilitate laying and use. However, the surface of the fluoroplastic outer sheath is very smooth, the surface tension is small (only about 1 / 7 of the surface tension of the PVC outer sheath), and the adhesion is poor. Ink printing)...
