Manufacturing method of high temperature resistant printing rotary screen

Abstract

The invention discloses a manufacturing method of a high temperature resistant printing rotary screen. The manufacturing method sequentially comprises the following steps of (1) preparing a die; (2) plating for the first time, and manufacturing a single screen; (3) preparing an additive, wherein the new additive is prepared from chloral hydrate for replacing saccharin sodium salt, 1,4-butynediol and deionized pure water; (4) plating for the second time, and adding the additive in the step (3) to a plating bath plated for the second time; and (5) processing a finished product. The manufacturing method has the advantages of simple step and convenience in operation, and a bath solution and the new additive are matched, so that the forming effect of the printing rotary screen is guaranteed, and the printing rotary screen has the characteristics of high temperature resistance, high rigidity, good toughness and durability; in addition, the new additive is prepared from the chloral hydrate for replacing the saccharin sodium salt, so that the brightness of the printing rotary screen is reduced, a frosted effect is generated, when plate making is performed on the printing rotary screen, the sizing is easy, and the phenomena of sticking and the like cannot occur.

Description

technical field [0001] The invention relates to a method for manufacturing a printing rotary screen used in the field of textile printing, in particular to a method for manufacturing a printing rotary screen with high temperature resistance, strong rigidity, good toughness and durability. Background technique [0002] Printing rotary screen, also known as printing nickel screen, is a necessary consumable equipment for rotary screen printing machines. It is a cylindrical cylinder with no joints and a specific mesh on the surface. There are 10 meshes, 20 meshes, 30 meshes, 40 meshes, 60 meshes, 80 meshes, 100 meshes, 125 meshes, 135 meshes, 155 meshes, 165 meshes, 185 meshes, 195 meshes, etc. , the circumference is 640 mm, 688 mm, 725 mm, 819 mm, 914 mm, 1018 mm, etc., and the length is 1420 mm to 3500 mm in different combinations, with hundreds of specifications. [0003] The production of printed rotary screen generally adopts the secondary electroplating method. The first ...

AI Technical Summary

Problems solved by technology

[0007] 1. Its base layer made by nickel electroplating, on the top surface and the bottom surface of the base layer, use two intermediate layers of copper electroplating, the outer layer of nickel electroplating is plated on the surface of these two intermediate layers respectively, and its preparation method is to adopt nickel electroplating The copper-nickel three-time composite electroplating method must be electroplated in three different plating tanks, the workpiece moves frequently in and out of the plating tank, the labor efficiency is low, and the actual operability is low;

[0008] 2. Using nickel-copper-nickel three-time composite electroplating method, the printed circular screen produced is composed of two layers of copper substrate and three layers of nickel substrate. When baking at high temperature, due to the different expansion coefficients of copper and nickel, it is easy to cause The delamination phenomenon of the net, the service life is short;

[0009] 3. The printed circular screen produced by nickel-copper-nickel three-time composite electroplating method has two layers of copper substrate in the middle. After recirculation at room temperature and high temperature or gluing and high temperature curing, the copper substrate is too soft and easy to produce folds. ,Affect
