Description

Wear-resistant long-service-life printing screen Technical Field The utility model relates to the technical field of screen plate structures, in particular to a wear-resistant long-service-life printing screen plate. Background The screen is an important tool for screen printing, is mainly formed by weaving a screen material of Teflon fiber, nylon fiber or metal material in a crossed mode in the warp and weft directions and then fixing the screen material on a screen frame in a stretching mode through a certain tension, and can control the amount of ink penetrating through the screen printing besides forming a screen pattern, so that the screen has great influence on printing precision, printing thickness and printing penetration. In the printing process, the pressing pressure of the scraper surface and the depth of the scraper easily cause the abrasion of specific points of the screen plate, so that the service life of the screen plate is reduced, and the expenditure of the use cost is increased. Disclosure of utility model The utility model aims to provide a wear-resistant long-service-life printing screen, and aims to solve the problems that in the prior art, the pressing pressure of a scraper surface and the depth of a scraper easily cause the abrasion of a specific point position of the screen, so that the service life of the screen is reduced, and the use cost is increased. In order to achieve the above purpose, the utility model provides a wear-resistant long-life printing screen plate, which comprises a screen frame, a tension metal wire mesh, a primer layer, a PI layer, a first composite material layer, a second composite material layer, an anti-abrasion component and an auxiliary component, wherein the tension metal wire mesh is fixedly connected with the screen frame and positioned on the inner side wall of the screen frame, the primer layer is fixedly connected with the tension metal wire mesh and positioned above the tension metal wire mesh, the PI layer is fixedly connected with the primer layer and positioned above the primer layer, the first composite material layer is fixedly connected with the PI layer and positioned above the PI layer, the second composite material layer is fixedly connected with the tension metal wire mesh and positioned below the tension metal wire mesh, and the anti-abrasion component is arranged above the first composite material layer and the auxiliary component is connected with the screen frame. The wear-resistant assembly comprises a wear-resistant coating and an antistatic coating, wherein the antistatic coating is fixedly connected with the first composite material layer and is positioned above the first composite material layer, and the wear-resistant coating is fixedly connected with the antistatic coating and is positioned above the antistatic coating. The wear-resistant coating is made of ceramic components and has the main effects of resisting mechanical friction between a screen cloth bearing surface and printing stock and ink particles in the repeated printing process through a surface structure with high hardness and low friction coefficient, avoiding the reduction of printing precision caused by abrasion deformation of meshes, and prolonging the service life of the screen printing plate. The anti-wear assembly further comprises an anti-sticking coating, wherein the anti-sticking coating is fixedly connected with the wear-resistant coating and is positioned above the wear-resistant coating.
