Cable lettering ink

Abstract

The invention belongs to the field of printing technology, and particularly relates to cable lettering ink which is characterized by comprising the following raw materials in parts by weight: 4-6 parts of polyvinyl chloride resin, 5-9 parts of acrylate polymer, 30-40 parts of methyl ethyl ketone, 13-18 parts of toluene, 5-10 parts of isobutyl methacrylate, 10-18 parts of tetrahydrofuran, 3-5 parts of benzidine yellow or titanium dioxide or lithopone with fineness of 400-800 meshes, 6-10 parts of 2-lead ethylcaproate, 0.3-0.5 part of methylparaben or propylparaben or butylparaben and 3-4.5 parts of butyl acetate. The invention also discloses a preparation method of the lettering ink. The cable lettering ink and the preparation method provided by the invention have the main beneficial effects that the preparation method is simple and easy to master, and the qualified rate of the finished product is high; the lettering ink has the advantages of high adhesion, high drying speed, bright luster and longer shelf life.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a cable printing ink, which is suitable for jet printing on polyvinyl chloride or flame-retardant material products. Background technique [0002] With the continuous development of science and technology, the demand for cables from all walks of life is increasing. As an important basic industry, the cable industry has become the second largest manufacturing industry after the automobile industry in China. In order to achieve the purpose of identification, the surface of the cable usually needs to be printed with distinguishing marks, length, manufacturer, year of manufacture, cable model and specification, etc. At present, there are two main methods of printing on the surface of cables: one is called embossing, which is to make blocks in advance, and then use thermal transfer printing ribbons to press the blocks on the printing ribbons. The printing is completed by...

AI Technical Summary

Problems solved by technology

Since the embossing method is mechanical, it is difficult to meet the requirements of rapid production, so it is being gradually eliminated

Existing inkjet printing inks often have low adhesion, slow drying speed, and poor gloss after spraying on the surface of polyethylene-based wire and cable sheaths, which greatly affects the correct use of the product

Due to the special material composition of polyvinyl chloride, therefore, the printing ink in the prior art is used on the goods of polyvinyl chloride or flame-retardant material, and effect is bad, mainly is that adhesion is poor, and printing is easy to come off; And, printing ink It is easily oxidized; the shelf life is short
