Problems solved by technology

Obviously, the traditional screen processing method is especially not conducive to the reduction of screen production cost in small batch, multi-variety and multi-color printing production. Therefore, the technology of stripping and reusing screen printing after screen printing is discussed in order to reduce the production cost of enterprises.

Embodiment 1

[0018] The main stripping agent is one of hydrogen peroxide, sodium hypochlorite and potassium permanganate. The peeling aid is prepared according to the mass ratio of the components shown in Table 1.

[0019] The main stripping agent: the auxiliary stripping agent is configured into a stripping agent according to the above composition, and then the stripping agent: water is mixed according to the mass ratio of 80:20 to make a degumming solution, and the pH of the degumming solution is adjusted to 4-12 with HCI or NaOH, and then Submerge the printing screen in the degumming solution, and degumming the printing screen at 95°C for 15 minutes, the photosensitive adhesive can be completely removed, and the residue after removing the photosensitive adhesive can be recycled after being filtered by impurities. The degummed printing screen meets the quality requirements for reuse after testing.

[0020] According to Table 1, different embodiments can be obtained by adjusting differen...

Embodiment 2

[0025] Configure the stripping agent according to the mass ratio of the main stripping agent: auxiliary stripping agent = 100:0, and then prepare the degumming solution according to the ratio of stripping agent: water = 75:15, adjust the pH of the degumming solution to 8.5, and process the printing at a temperature of 80°C 60 minutes for the screen version, the photosensitive glue of the printing screen version is completely removed.

Embodiment 3

[0027] Prepare the stripping agent according to the mass ratio of the main stripping agent: auxiliary stripping agent = 98:2, and then prepare the degumming solution according to the ratio of stripping agent: water = 75:15, and adjust the pH of the degumming solution to 9. The mass ratio of each component of the peeling aid is anionic surfactant containing sodium sulfonate group:polyoxyethylene nonionic surfactant:alcohol=0:0:100. Process the printing screen plate for 45 minutes at a temperature of 60° C., and the photosensitive glue of the printing screen plate is completely removed.

Abstract

The invention discloses a photosensitive rubber stripping agent for a printing screen and a stripping method, which belong to the field of textile printing. The invention is characterized in that: the stripping agent comprises 45-100 percent by mass of main stripping agent and 55-0 percent by mass of auxiliary stripping agent, wherein the main stripping agent is selected from any one of an inorganic peroxide, a compound containing a chlorine element with the oxidizing capability and a high-valence metal oxidant not containing any chlorine element; and the auxiliary stripping agent is selectedfrom one or more of an anion surfactant containing a sodium sulfonate group, a polyethylene glycol nonionic surfactant and alcohol. Due to the adoption of the photosensitive rubber stripping agent disclosed by the invention, photosensitive rubber can be stripped from the printing screen without damaging the printing screen, recycling of the printing screen is realized, the production cost is saved, and the consumption of resources is lowered.

Description

Technical field: [0001] The invention relates to a printing screen photosensitive adhesive stripping agent and a stripping method, belonging to the field of textile printing. Background technique: [0002] China is a global textile printing powerhouse, with a total textile printing output of about 5-6 billion meters, ranking first in the world. Among the various printing processes of textiles, the production of screen printing including flat screen and rotary screen printing accounts for the highest proportion, among which the output of rotary screen printing alone accounts for about 59% of the total number of printing products. In terms of regional distribution, India, Japan, South Korea and Thailand in Asia, Spain, Portugal and Italy in Europe mainly use flat screen printing. [0003] As people's demand for personalized and fashionable clothing and decorative fabrics changes, the global textile trade also tends to be in the direction of small batches, multiple varieties,...
