Embodiment 1

[0023] The preparation example of the screen cleaning agent for screen printing is as follows, and the present invention is not limited thereto.

Embodiment 2

[0026]Using a mechanical stretcher, a 325-mesh fabric-shaped stainless steel wire mesh with a thickness of 64.0 μm was stretched on an aluminum die-casting frame with a size of 320×320 mm to produce two stretch plates. One of the above two plates was cleaned with the cleaning solution formulated in Example 1, and the other plate was cleaned with a neutral cleaning agent (Murakami Precision Plate (Kunshan) Co., Ltd. MSP detergent) sold on the market. Clean up. The above two plates were respectively made of diazo series photosensitizer SP-9400 from Murakami Precision Plate (Kunshan) Co., Ltd. sold in the market to form photosensitive plastic films with a thickness of 15 μm. Next, prepare a 30-line 30% halftone dot image polyester positive film, stick the film surface of the positive film close to the film surface of the above-mentioned photosensitive film layer, use a 3kw metal halide lamp as a light source, and carry out the process for 90 seconds from a distance of 80cm. of U...

Embodiment 3

[0030] Using a mechanical stretcher, a 64.0 μm-thick, 325-mesh fabric-shaped stainless steel wire mesh was stretched on an aluminum die-casting frame with a size of 320×320 mm to produce four stretching plates. Among the above-mentioned 4 plates, 2 plates are cleaned with the cleaning liquid prepared in Example 1, and the remaining 2 plates are cleaned with a neutral cleaning agent (Murakami Precision Plate (Kunshan) Co., Ltd., the screen cleaning agent MSP) sold on the market. detergent) for cleaning. After cleaning, a photosensitive resin film with a thickness of 15 μm was formed on the plate with diazo series photosensitizer SP-9400 manufactured by Murakami Precision Plate (Kunshan) Co., Ltd. respectively. These plates were subjected to a storage test in a light-shielded state in an environment with a humidity of 40 to 50% and a temperature of 20 to 50°C. After cleaning the plate with the cleaning agent of the present invention and the neutral cleaning agent of the compari...

Abstract

The invention relates to a silk screen cleaning agent for silk screen printing, which consists of 100 portions of aqueous solution and 0.01 to 10 portions of phosphoric acid containing ionic compound in portion by weight, wherein the aqueous solution is prepared by mixing 12 to 50 percent of water-soluble organic solvent and 50 to 88 percent of deionized water in percentage by weight. Compared with the prior art, the silk screen cleaning agent can prevent iron ions from being separated out from the surface of a stainless steel silk screen, prevent dark reactions of diazonium series photosensitive materials, persistently obtain the most suitable picture features, and keep the hydrophilic property on the surface of stainless steel silk screen, so the adherence of the photosensitive material consisting of the silk screen cleaning agent and water-soluble resin is improved, and subtle patterns of the plate-making process step and the printing process step are prevented from being broken off.

Description

technical field [0001] The invention relates to a cleaning agent for a combined screen printing plate, in particular to a related cleaning solution for cleaning a screen before coating photosensitive materials. 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 adhesive film on the surface of the printed object, because it can form fine graphics and has excellent mass production. , so it is widely used in many industrial fields. [0003] In the field of manufacturing electronic parts, the above-mentioned screen printing is used because of its high precision and excellent mass production. With the technological trend in this field in recent years, the size of parts has become smaller and more and more It is required to produce finer printed graphics with higher precision and higher density. The state of being able to produce fine printed patterns with high precision is...
