Benzene ring containing compound, sealing gel, process for preparing same and use thereof
View Patent ↗The disclosure provides a benzene ring containing compound, sealing gel, a process for preparing the same and use thereof. The compound has the following Formula (I), wherein R 1 and R 2 are the same or different, and represent alkyls of 1˜4 carbon atoms, respectively. The sealing gel of the disclosure comprises one or more compounds as shown by Formula (I). The sealing gel of the disclosure not only has high binding strength to a glass substrate, but also has a good binding performance to the oriented film, thereby preventing the drop of the binding performance between the colored film substrate and the array substrate, while also decreasing the contamination of external impurities to the liquid crystals in the box.

wherein R 1 and R 2 are the same or different, R 1 represents an alkyl of 1˜4 carbon atoms, and R 2 represents an alkyl of 1˜4 carbon atoms.
2. A sealing gel comprising one or more compounds as shown by Formula (I),
wherein each R 1 and R 2 are the same or different, R 1 represents an alkyl of 1˜4 carbon atoms, and R 2 represents an alkyl of 1˜4 carbon atoms.
3. The sealing gel according to claim 2 , wherein R1 represents methyl or t-butyl, and R2 represents methyl or t-butyl, and by Formula (I), the ratio of the total mole number of methyl represented by R1 and R2 to the total mole number of t-butyl represented by R1 and R2 is 9:1˜1:1.
4. The sealing gel according to claim 3 , wherein the ratio of the mole number of methyl represented by R1 and R2 to the mole number of t-butyl represented by R1 and R2 is 7:3.
5. The sealing gel according to claim 2 , wherein the sealing gel further comprises a photoinitiator.

(1) mixing the compound as shown by Formula (II) and a polymerization inhibitor to form Mixture 1;
(2) mixing the compound as shown by Formula (III) and a catalyst to form Mixture 2;
(3) dropping Mixture 2 into Mixture 1 under agitation at 40˜100° C.; and
(4) after the completion of dropping, continuing the reaction at 80˜120° C. for another 6˜10 hours.
10. The process according to claim 9 , wherein the polymerization inhibitor is p-hydroxylanisole.
11. The process according to claim 9 , wherein the catalyst is tetraethyl ammonium bromide.
12. A method of using the sealing gel according to claim 2 in the manufacture of a display device, wherein the sealing gel is used to bind an array substrate and a colored film substrate in the display device.
