Please refer to fig. 1. The invention firstly provides the composite material screen printing plate with low cost, which can reduce the use of expensive metal screen cloth and save the cost of the screen printing plate while meeting the reliability.
Specifically, the composite material screen printing plate comprises a screen frame 1, a polymer screen cloth 2, a composite film layer 3 and a composite metal layer; for the sake of better description, the side of each layer of the screen facing the doctor blade is referred to as a doctor surface S1, and the side facing the printing material is referred to as a receiving surface S2.
The composite metal layer comprises a metal mesh 4 and a polymer adhesive film 5 arranged on the printing surface of the metal mesh 4; the polymer mesh 2 is of a square-shaped structure, and in order to better describe the corresponding relationship between the polymer mesh, the composite film layer 3 and the metal mesh 4, the square-shaped structure is respectively a square-shaped first part 21 and a second part 22 surrounding the periphery of the first part 21; similarly, the composite film layer 3 is also in a zigzag structure, and includes a first bonding region 31 in a zigzag shape, a second bonding region 32 surrounding the first bonding region 31, and a third bonding region 33 surrounding the second bonding region 32; the composite film layer 3 can attach the metal mesh cloth 4 to the center of the first part 21 of the polymer mesh cloth 2; in order to reduce the consumption of the metal mesh cloth 4, the size of the metal mesh cloth 4 is made as small as possible, so that after the metal mesh cloth 4 is attached to the polymer mesh cloth 2, an overlapped area does not exist between the edge of the metal mesh cloth and the inner edge of the polymer mesh cloth 2; that is, the printing surface of the first portion 21 is attached to the doctor surface of the third bonding area 33; the printing surface of the first bonding area 31 is attached to the scraper surface of the metal mesh cloth 4, and the second bonding area 32 is further arranged between the first bonding area 31 and the third bonding area 33, so that the structure can be realized. In one embodiment, the width of the second bonding area 32 is not less than 0mm, and when the width of the second bonding area 32 is equal to 0, that is, in the thickness direction, the edge of the metal mesh 4 and the edge of the zigzag shape of the polymer mesh 2 are located on the same straight line, that is, just overlapped.
In order to ensure the reliability of the bonding and the minimization of the amount of the metal mesh cloth 4, the width of the first bonding area 31 is 10-15mm, that is, the edge of the composite film layer 3 is spaced from the edge of the pattern printing area by a certain width.
In order to ensure the reliability of the screen printing plate and avoid slurry leakage between the polymer mesh cloth 2 and the metal mesh cloth 4, when the polymer adhesive film 5 is attached to the printing surface of the metal mesh cloth 4, the edge of the polymer adhesive film is further attached to at least part of the second bonding area 32 and/or the third bonding area 33, as shown in fig. 1, the portion of the polymer adhesive film 5 attached to the metal mesh cloth 4 is attached to the whole second bonding area 32 and the part of the third bonding area 33.
Further, the edge of the polymer adhesive film 5 is at least partially attached to the second bonding area 32 and/or the third bonding area 33 to form an overlapping area, and the width of the overlapping area is greater than 10mm, so that a bonding force between the polymer adhesive film 5 and the composite film layer 3 is ensured.
In order to further ensure the printing quality by equalizing the pressure during printing, the printing surface of the overlapping area corresponding to the composite film layer 3 is flush with the printing surface of the metal mesh cloth 4.
Furthermore, in order to better attach the composite film layer 3 and the polymer adhesive film 5, the composite film layer 3 and the polymer adhesive film 5 are made of materials with the same or similar physical properties. In one embodiment, the composite film layer 3 and the high-molecular adhesive film 5 are made of one or more of PET, PE, PA, PI, PU, PVC, PP, PTFE, PMMA, PS, and EVOH.
As will be described in detail below, the method for manufacturing the composite material screen printing plate with low cost includes the following steps:
s1, selecting a composite film layer and a polymer adhesive film with the same or similar physical properties; the term "the same physical properties" means that the composite film layer and the polymer adhesive film can withstand the same or similar temperature without affecting their respective viscosities when baked at a high temperature.
S2, determining the size of the metal mesh cloth according to the size of the opening pattern to be printed; the edge of the metal mesh cloth is away from the edge of the opening pattern required by the metal mesh cloth by a certain distance, so that the reliability of attachment can be ensured, and the using amount of the metal mesh cloth can be reduced.
S3, preparing the polymer mesh cloth, and reserving a first part which is in a shape of a Chinese character 'hui' and is attached to the composite film layer.
S3, preparing a metal composite layer, wherein the metal composite layer comprises a metal mesh cloth with a printing surface attached or without a polymer adhesive film; namely, the metal composite layer may be a metal mesh cloth without a polymer adhesive film under one condition, or a metal mesh cloth with a polymer adhesive film attached thereto under another condition.
S4, combining the polymer mesh cloth with the metal composite layer through a composite film layer to enable a scraper surface of the metal mesh cloth to be attached to a printing surface of a first combination area of the composite film layer, and a scraper surface of a third combination area of the composite film layer to be combined with the printing surface of the polymer mesh cloth to obtain a composite net;
s5, the composite net is stretched and fixed onto a net frame through tension.
Further, when the metal composite layer comprises metal mesh cloth with a printing surface attached with a polymer adhesive film, before the metal composite layer is combined with the polymer mesh cloth, a polymer adhesive film is attached to the printing surface of the metal mesh cloth, so that the edge of the polymer adhesive film extends to the periphery of the metal mesh cloth, and the edge of the polymer adhesive film is at least partially attached to the second combination area and/or the third combination area of the composite film layer; and the metal composite layer has a formed opening pattern; when the metal composite layer is bonded with the polymer mesh cloth through the composite film layer, on one hand, a first bonding area of the composite film layer is bonded with the metal mesh cloth, and a third bonding area of the composite film layer is bonded with the polymer mesh cloth; on the other hand, the edge of the polymer adhesive film is ensured to be at least partially attached to the second bonding area and/or the third bonding area.
In other embodiments, when the metal composite layer includes a metal mesh having a printing surface without a polymer film attached thereto, the polymer mesh is bonded to the metal mesh through the composite film layer, and after S5, the polymer film is attached to the printing surface of the metal mesh, and the edge of the polymer film is at least partially attached to the second bonding region and/or the third bonding region of the composite film layer, and finally the opening pattern is obtained by processing.
Through the structure, the using amount of the metal mesh cloth can be reduced, and the attaching process can be flexibly selected, namely, one mode is that the polymer adhesive film and the metal mesh cloth are firstly combined to obtain the metal composite layer containing the opening patterns, and then the metal composite layer is attached to the polymer mesh cloth, so that a user does not need to further process, and the use of the user is simplified; the other mode is that after the metal mesh cloth is attached to the polymer mesh cloth, the polymer adhesive film is compounded to meet the requirement of a user for special opening patterns, the reliability of the screen printing plate can be guaranteed without filling joint filling glue and the like in the whole process, and the manufacturing process is simplified.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
