Problems solved by technology

Because these two kinds of printing circular screens are made of nickel, they have good elasticity, are easy to round and wear-resistant, but they are not resistant to high temperature. When they are heated for rounding or heating and curing photosensitive adhesive, the nets will become brittle. If it is printed on the machine again, it is prone to disconnection and the service life is short

Embodiment Construction

[0017] With reference to the accompanying drawings, the high temperature resistant printing rotary screen includes an inner layer 1 made of nickel electroplating, two intermediate layers 2 of electrolytic copper plating are fixed on the top surface and the bottom surface of the inner layer 1, and the two intermediate layers 2 The outer layer 3 with nickel plating is respectively fixed on the surface, and the tapered through-hole 4 arranged according to the thickness direction is densely covered on the printed circular net composed of the inner layer 1, two middle layers 2 and two outer layers 3, as shown in the figure What the through hole 4 of the shown is biconical, and the thickness of inner layer 1, each middle layer 2 and each outer layer 3 respectively accounts for 26%-38%, 13%-16% and 17% of the total thickness of printed rotary screen -21%, the specific thicknesses of the inner layer 1, each middle layer 2 and each outer layer 3 of the printing rotary screens of four sp...

Abstract

A refractory roller screen for printing is composed of an internal plated Ni layer, two external plated Ni layers, and two intermediate plated Cu layers between internal and external layers, and has the dense conic through holes. Its preparing process features electroplating three times. Its advantages are high cold elasticity, high printing effect, long service life and low cost.

Description

technical field [0001] The invention relates to a printing rotary screen and a preparation method thereof, more specifically to a high temperature resistant printing rotary screen and a preparation method thereof. Background technique [0002] The existing printing rotary screens, including standard screens and PENTA screens, are all made of nickel, so they are also called printed nickel screens. The cross-section of the standard net is densely covered with a number of single-cone micropores, and the cross-section of the PENTA net is densely covered with a number of double-cone micropores, that is, the diameter of the micropores is the largest on the top and bottom of the PENTA net, and the diameter is the largest in the net thickness. The central part has the smallest diameter. Compared with the standard net, the PENTA net has more micropores per unit area, higher opening ratio, and better printing effect. In the preparation method, the standard mesh is to use the mesh mo...
