Abstract

Disclosed is a glass paste which is excellent in compatibility of a binder resin component, adhesion to a substrate / dry film resist (DFR), and low-temperature sinterability. This glass paste can be easily ground by sandblasting without causing a breakdown of a partition wall since it has high dried film strength. Specifically disclosed is a glass paste containing a (meth)acrylate copolymer, a cellulose resin, a glass powder and an organic solvent. The (meth)acrylate copolymer is composed of at least one (meth)acrylate monomer A selected from the group consisting of cyclohexyl(meth)acrylate, isobutyl(meth)acrylate, isobornyl(meth)acrylate, ethyl methacrylate, n-propyl methacrylate and isopropyl methacrylate, and a (meth)acrylate monomer B having one or more hydroxy groups. The composition ratio of the (meth)acrylate monomer A in the (meth)acrylate copolymer is 60-99.9% by weight, while the composition ratio of the (meth)acrylate monomer B having one or more hydroxy groups is 0.1-40% by weight.

Description

technical field

[0001] The present invention relates to an adhesive resin component that has excellent compatibility with substrates and dry film resists (DFR), excellent low-temperature sinterability, can be easily cut by sandblasting, has high dry film strength, and does not Glass paste for partition damage caused by sandblasting. Background technique

[0002] A plasma display is a type of flat display device that utilizes light emission caused by discharge. It has attracted attention as a promising color display device because of its fast response speed, wide viewing angle, good color purity, and easy enlargement of the screen.

[0003] A plasma display panel is generally provided such that a front glass substrate and a rear glass substrate face each other, and a plurality of partition walls are formed in the space between these substrates to separate the gas discharge section.

[0004] A sandblasting method is known as a typical method of forming the partition wall. Th...

Examples

Embodiment 1

[0057] In a 2L separable flask equipped with a stirrer, a cooler, a thermometer, a hot water bath, and a nitrogen inlet, 80 parts by weight of cyclohexyl methacrylate (manufactured by NOF Corporation: BLEMMER CHMA), 2,3 - 20 parts by weight of dihydroxypropyl ester (manufactured by NOF Corporation: BLEMMERGLM), mercaptosuccinic acid (manufactured by Wako Pure Chemical Industries, Ltd.) as a chain transfer agent, 100 parts by weight of ethyl acetate (manufactured by Wako Pure Chemical Industries, Ltd.) as an organic solvent , to obtain a monomer mixture.

[0058] Dissolved oxygen was removed by bubbling the obtained monomer mixture with nitrogen for 20 minutes, and then the inside of the separable flask system was replaced with nitrogen, and the temperature was raised while stirring until the hot water bath boiled. A solution obtained by diluting the polymerization initiator with ethyl acetate was added. In addition, the polymerization initiator was added several times during ...

Embodiment 2

[0063] A glass paste was prepared in the same manner as in Example 1 except that the chain transfer agent used was changed to mercaptopropylene glycol (manufactured by Wako Pure Chemical Industries, Ltd.) and the weight average molecular weight was changed to the value described in Table 1.

Embodiment 3

[0065] The chain transfer agent used was changed to dodecyl mercaptan (manufactured by Wako Pure Chemical Industries, Ltd.), and the weight average molecular weight was changed to the value recorded in Table 1, except that it was carried out in the same manner as in Example 1 to prepare a glass paste .
