Problems solved by technology

[0003] Existing composite steel mesh plates generally use composite technology, using two materials, steel mesh and polyester mesh, using hot-melt or adhesive technology, combining the edge of the steel mesh with the polyester mesh, and then bonding the polyester mesh inside the interface. The polyester mesh is cut off, and only the steel mesh is kept in the c

Abstract

The invention discloses a preparation method of a composite screen printing plate. The preparation method is characterized by comprising the following steps of: providing a polyester screen printing plate, a hot-melt adhesive sheet (5) and steel wire mesh cloth (4), wherein the polyester screen printing plate comprises polyester mesh cloth; emptying the center of the polyester mesh cloth (1) to form a cavity (3); placing the hot-melt adhesive sheet (5) on the polyester mesh cloth (1) to make sure that the hot-melt adhesive sheet (5) covers the boundary of the cavity (3) and a part of the cavity (3) is exposed; placing the steel wire mesh cloth (4) on the hot-melt adhesive sheet (5) and covering the cavity (3); and combining the steel wire mesh cloth (4) with the polyester mesh cloth (1) through the hot-melt adhesive sheet (5) in a melting manner. According to the preparation method disclosed by the invention, the steel wire mesh cloth is combined with the step of the polyester mesh cloth in a hot-melting manner through the hot-melt adhesive sheet so that a gradual bevel interface is formed at the step, the quality of the screen printing plate is improved, and the defects that the plate surface is out of flatness, the coated film thickness is not uniform, explosion is easily generated and the like are alleviated.

Description

technical field [0001] The invention relates to the technical field of screen printing, in particular to a method for preparing a composite screen. Background technique [0002] At present, there are two main types of stainless steel wire mesh, one is full steel mesh, and the other is composite steel mesh. The all-steel screen is made by raising the stainless steel wire mesh to a certain tension, and then bonding it to the screen frame as a whole to form a screen. Except for the screen frame, the entire screen surface is composed of stainless steel wire. Composite steel wire mesh: First, cut the stainless steel mesh into pieces according to the size and angle requirements; then compound the stainless steel mesh in the polyester mesh; then bond the composite mesh on the screen frame to form a mesh Version. Except for the screen frame, the mesh surface is composed of polyester mesh cloth and stainless steel wire mesh cloth. Composite steel wire mesh greatly reduces the amo...
