Cable lettering ink

Abstract

The invention belongs to the technical field of printing, and in particular relates to a cable printing ink, which is characterized in that it contains the following raw materials in parts by weight: polyvinyl chloride resin: 4-6 parts, acrylate polymer: 5-9 parts Parts, methyl ethyl ketone: 30-40 parts, toluene: 13-18 parts, isobutyl methacrylate: 5-10 parts, oxolane: 10-18 parts, benzidine yellow or fineness of 400-800 mesh titanium dioxide or lithopone: 3-5 parts, lead 2-ethylhexanoate: 6-10 parts, methylparaben or propylparaben or butylparaben: 0.3-0.5 Parts, butyl acetate: 3 to 4.5 parts; the invention also discloses a preparation method of the printing ink. The invention has the following main beneficial effects: the production method is simple and easy to grasp, and the qualified rate of finished products is high; the printing ink has high adhesion, fast drying speed, bright luster and long 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
