Problems solved by technology

However, the manufacturing method using these adhesives has the following disadvantages: when applying the adhesive, in order to apply only the required part, it is necessary to spend labor and cost to paste the protective tape (hereinafter referred to as maintenance), and the operator's It is also difficult to control the adhesive coating thickness between
Therefore, the products produced are unstable and cannot be said to have no effect on the final printing
In addition, as a material issue, epoxy resin adhesives have poor workability due to the long curing time, and UV adhesives have poor workability due to the need to block ultraviolet rays from indoor lighting.
In addition, drug contact dermatitis caused by adhesives places a heavy burden on operators

Embodiment 1

[0042] see Figure 1-12 ,Such as Figures 13 to 15 As shown, firstly, the polyester screen 12 is bonded to the plate frame 11 with an adhesive in a state of being tensed up, down, left, and right, and then a sheet-shaped thermoplastic polyethylene with a thickness of 150 μm is placed on the polyester screen 12. Sheet, and the metal stainless steel wire mesh 14 is superimposed on the sheet-shaped thermoplastic polyethylene sheet, pressed on the thermoplastic sheet with the condition of 110 ℃ / 2kg f, and it can be combined in 2 minutes. The thickness of the bonded portion was measured to be 110 μm to 115 μm, with very little variation.

Embodiment 2

[0044] First, the polyester screen is bonded to the frame with an adhesive in the state of tensioning up, down, left, and right, and then a thin sheet of thermoplastic plastic with a thickness of 10 μm is placed on the polyester screen, and the metal screen is superimposed on the sheet. On the thermoplastic plastic, carry out hot pressing operation at 80°C, and then cut off the inner polyester mesh to obtain the product.

Embodiment 3

[0046] First, the polyester screen is bonded to the frame with a polyethylene derivative adhesive in a state of tensioning up and down, left and right, and then a thin sheet of thermoplastic plastic with a thickness of 300 μm is placed on the polyester screen, and the wire screen is attached to the frame. Superimposed on the sheet-shaped thermoplastic, at 150°C, heat the thermoplastic part from both sides while applying pressure to it, perform hot-pressing operation, and then cut off the inner polyester mesh to obtain the product.

Abstract

The invention relates to a method for manufacturing a silk screen printing composite plate through hot pressing, which comprises the following steps: firstly, adhering a polyester silk screen to a plate frame with an adhesive; secondly, setting a flaky thermoplastic plastic on the polyester silk screen, superposing a gauze screen on the flaky thermoplastic plastic, and performing hot pressing operation at a temperature of between 80 and 150 DEG C; and thirdly, cutting off the internal polyester silk screen to obtain the product. Compared with the prior art, the method has the characteristics of reducing the process steps, shortening the operating time, reducing the irregularity among operators, lightening the burdens on the operators and the like.

Description

technical field [0001] The invention relates to a method for preparing a combined stretched screen printing plate, in particular to a method for manufacturing a screen printing composite plate by hot pressing, which is composed of a low-rigidity support screen constituting the edge part and a high-rigidity printing screen constituting the inner peripheral part. Background technique [0002] Screen printing is a plate-making (screen printing plate) that uses screen printing to form a printing film composed of ink and paste on the surface of the object to be printed, because it can form fine patterns and has excellent mass productivity , so it is widely used in many industrial fields. Especially in the field of manufacturing electronic parts, the above-mentioned screen printing is used because of its high precision and excellent mass production. The printing screen plate used here is formed by a screen made of synthetic resin such as nylon or polyester. The supporting body sc...
