Example Embodiment

[0035] Example 1

[0036] 200 g of diethylene glycol methyl butyl ether acetate, 100 g of butyl methacrylate, and 10 g of ethyl cellulose were mixed and stirred 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 and stirred for 5 hours. Continue to stir until the bubbles disappear, set aside. Then, a lead-free barrier is fabricated using a technique known to those skilled in the art. The composition prepared above is evenly brushed on the barrier wall and dried. Paste the DFR film on the barrier layer, and produce the DFR film pattern through the traditional exposure and development process. The pattern is etched by the sandblasting etching method to simultaneously etch away the com...

[0037] Example 2

[0038] 200 g of diethylene glycol methyl butyl ether acetate, 100 g of butyl methacrylate, and 10 g of ethyl cellulose were mixed and stirred until completely dissolved. Add 35g of glass powder, 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 21.8wt% BaO. Add 130 g of hydroxymethacrylate, 5 g of dibutyl phthalate, and 5 g of isopropanol, and stir for 5 hours. The stirring was continued until the bubbles disappeared, and the composition of Example 2 was obtained. Then, using the above-prepared composition, the barrier ribs were manufactured by the same method as in Example 1.

[0039] Example 3

[0040] 200 g of diethylene glycol methyl butyl ether acetate, 100 g of butyl methacrylate, and 10 g of ethyl cellulose were mixed and stirred until completely dissolved. Add 10g of glass powder, 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. The stirring was continued until the bubbles disappeared, and the composition of Example 3 was obtained. Then, using the above-prepared composition, the barrier ribs were manufactured by the same method as in Example 1.

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...
