Problems solved by technology

The interface effect between lead-free material and DFR dry film is poorer than that of lead-containing material
The photoresist dry film currently used often cannot be well bonded to it due to the rough structure of the surface layer of the barrier, resulting in defects such as barriers that are prone to collapse due to the penetration of the developer during the development process.

Embodiment 1

[0036] Mix 200 g of diethylene glycol methyl butyl ether acetate, 100 g of butyl methacrylate, and 10 g of ethyl cellulose, and stir until completely dissolved. Add 20g of glass powder, wherein, based on the total weight of the glass powder, the mass ratio of the glass powder composition is: 0.5wt% SiO 2 , 50wt% ZnO, 35wt% B 2 o 3 , 0.2wt% Na 2 O, 14wt% BaO, and 0.3wt% K 2 O. Then, 100 g of 2-hydroxyethyl methacrylate, 5 g of dibutyl phthalate, and 5 g of isopropanol were added, followed by stirring for 5 hours. Continue to stir until the bubbles disappear, set aside. Lead-free barrier ribs are then fabricated using techniques known to those skilled in the art. Brush the above prepared composition evenly on the barrier and dry it. The DFR film is pasted on the barrier layer, and the DFR film pattern is produced through the traditional exposure and development process. Sand blasting etching is used to etch the pattern, and the composition of the present invention and ba...

Embodiment 2

[0038] Mix 200 g of diethylene glycol methyl butyl ether acetate, 100 g of butyl methacrylate, and 10 g of ethyl cellulose, and stir until completely dissolved. Add glass powder 35g, wherein, based on the total weight of the glass powder, the mass ratio of the glass powder composition is: 3wt% SiO 2 , 40wt% ZnO, 35wt% B 2 o 3 , 0.2wt% Na 2 O, and 21.8 wt% BaO. 130 g of methylol acrylate, 5 g of dibutyl phthalate, and 5 g of isopropanol were added, and stirred for 5 hours. Stirring was continued until the bubbles disappeared to obtain the composition of Example 2. Then, barrier ribs were fabricated by the same method as in Example 1 using the composition prepared above.

Embodiment 3

[0040] Mix 200 g of diethylene glycol methyl butyl ether acetate, 100 g of butyl methacrylate, and 10 g of ethyl cellulose, and stir until completely dissolved. Add glass powder 10g, wherein, based on the total weight of the glass powder, the mass ratio of the glass powder composition is: 5wt% SiO 2 , 30wt% ZnO, 45wt% B 2 o 3 , 5wt% Na 2 O, 12wt% BaO, and 3wt% K 2 O. 180 g of 2-hydroxyethyl methacrylate, 5 g of dibutyl phthalate, and 5 g of isobutanol were added, and stirred for 5 hours. Stirring was continued until the bubbles disappeared to obtain the composition of Example 3. Then, barrier ribs were fabricated by the same method as in Example 1 using the composition prepared above.

Abstract

The invention provides a composite for improving interfacial effect of a photoresist dry film and a barrier and a preparation and usage method thereof, and a method for manufacturing a barrier of a plasma display panel by utilizing the composite; the composite comprises glass powder, plasticizer, alkali solubility adhesive low polymer, dispersing agent, inorganic filler and solvent; by utilizing the composite and method of the invention, the combinability of the barrier and the photoresist dry film can be improved, so as to reduce the disadvantage that the barrier is easy to incline and collapse after sand blasting is carried out, and improve the finished product ratio.

Description

technical field [0001] The invention relates to a composition for improving the interface effect between a photoresist dry film and a barrier rib. The invention also relates to methods of using the composition in the manufacture of plasma displays. Background technique [0002] Plasma displays have many unique advantages, such as high and uniform screen brightness, no bright and dark areas, no influence of magnetic fields, no image distortion, strong environmental adaptability, memory characteristics, high contrast and high resolution, grayscale It can exceed 256 levels, fast picture response, viewing angle up to 160°, pure plane, thin thickness, etc. It is currently recognized as the most promising device for realizing large-screen wall-mounted TVs. [0003] In a plasma display panel (Plasma Display Panel, PDP), the barrier ribs have two functions of ensuring a discharge gap between substrates and preventing optical crosstalk between adjacent units. Therefore, the barrier...
