[0004] However, the glass disclosed in Japanese Patent Application Laid-Open No. 2001-163635 contains an alkali metal oxide for the purpose of lowering the softening point of the glass. Therefore, the peelability of the dry film protective film is deteriorated, and it is difficult to use the sandblasting method. next door problem

Embodiment Construction
[0010] Partition rib forming material for plasma display panel of the present invention containing ZnO-B with low melting point 2 o 3 -SiO 2 glass-like powder as the main constituent. Because only ZnO, B 2 o 3 and SiO 2 Three components, higher melting point than PbO glass, so, in ZnO-B 2 o 3 -SiO 2 In glass-like, Li is added at a mole % of 3% or more 2 O, Na 2 O, K 2 The alkali metal oxide of O lowers the melting point of the glass. In addition, the addition of an alkali metal oxide tends to lower the peelability of the dry film protection film and make it difficult to form partition walls by the blasting method. However, by controlling the content of alkali metal oxides below 10%, and the B 2 o 3 / (Li 2 O+Na 2 O+K 2 The proportion of O) is adjusted so that the molar ratio is in the range of 2.3 to 8.0, and the fall of the peelability of the dry film protection film is suppressed, whereby the partition wall can be formed by the sandblasting method.

Abstract
The invention provides material for partition wall of plasma display panel and glass composite for the wall, which can be sintered in the same temperature with the traditional material for partition wall without containing PbO. The material is formed by sand blasting and restrains the decrease of the stripping of the dry protection film even if the material contains alkaline metal oxides. The material for partition wall of plasma display panel of the invention contains glass powders and ceramic powders, and is characterized in that: the glass powder is composed of glass containing 35-60 mol %ZnO, 15-40 mol% B2O3, 1-20 mol% SiO2, 0-5 mol% Al2O3, 0-10 mol% BaO, 0-8 mol% Li2O, 0.02-10 mol% Na2O, 0.01-5 mol% K2O, Li2O+Na2O+K2O is 3-10 mol%, B2O3 / (Li2O+Na2O+K2O) is 2.5-8.0, K2O / Na2O is less than 0.50, and without PbO.
Description
technical field [0001] The present invention relates to a partition wall forming material for a plasma display panel and a glass composition for a partition wall forming material. Background technique [0002] The plasma display panel is a self-luminous flat-panel display device, which has excellent characteristics such as thinness and wide viewing angle, and is attracting attention as one of the most promising display devices because it can realize a larger screen. [0003] In a plasma display panel, generally, a front glass substrate and a rear glass substrate are arranged facing each other, and a plurality of barrier ribs (also referred to as barrier ribs) for dividing a gas discharge portion are formed in the space between these substrates. As a method of forming partitions, sandblasting is generally used. After forming partitions on a glass substrate, a dry film protective film is formed on it, and after exposure and development, unnecessary parts are removed by sandbla...
