preparation example Construction

[0042] During the preparation process of the bonded sheet, the above photoinitiator can be reacted by light irradiation such as ultraviolet rays, so as to initiate the curing reaction of the bond composition.

[0043]The specific kind of above-mentioned photoinitiator is not particularly limited, and its example can enumerate α-hydroxy ketone compound (such as IRGACURE (Yan Jia solid) 184, IRGACURE 500, IRGACURE 2959, DAROCUR (De firm) 1173, Ciba Specialty Chemicals company (Ciba Specialty Chemicals)); benzoyl formate (phenylglyoxylate) compounds (for example, IRGACURE 754, DAROCUR MBF, manufactured by Ciba Specialty Chemicals); dimethyl benzyl ketones (for example, IRGACURE 651 , manufactured by Ciba Specialty Chemicals); α-aminoketones (for example, IRGACURE 369, IRGACURE 907, IRGACURE 1300, manufactured by Ciba Specialty Chemicals); monoacylphosphines (MAPO) (for example, DAROCUR TPO, manufactured by Ciba Ciba Specialty Chemicals); diacylphosphine compounds (BAPO) (IRGACURE...

Embodiment 1

[0087]Partially polymerize 95 parts by weight of 2-ethylhexyl acrylate and 5 parts by weight of acrylic acid to prepare 100 parts by weight of a polymerizable compound, and mix it with ethylhexyl peroxycarbonate as the first thermal initiator 0.2 parts by weight of ester (PX47, initiation temperature: 47°C), 0.1 part by weight of 1-chloroethane hydroxyacetophenone (Irg 184) as a photoinitiator, tert-butyl pivalate ( A curable resin composition was prepared using 0.2 parts by weight of PX 75, t-Butyl peroxypivalate, manufactured by Century College, initiation temperature: 75°C. After injecting the above-mentioned curable resin composition between glass plates with a pitch of 3.5mm for casting, the first thermal curing step was performed at a temperature of 60°C for 60 minutes, followed by irradiating ultraviolet (UV) for 0.5 minutes to perform light curing. The curing step is followed by a second thermal curing step for 2 hours after the temperature is raised to 80° C., so as t...

Embodiment 2

[0089] A cured product layer was formed in the same manner as in Example 1 except that the photocuring step based on ultraviolet (UV) irradiation was increased to 1.0 minute.

Abstract

Provided are a curable compound, a photoinitiator, and a curable resin composition comprising at least two thermal initiators having different initiation reaction temperatures. Since the curable resin composition can improve a curing rate while having a high conversion rate, the curable resin composition is suitable for manufacturing thick films.

Description

technical field [0001] It relates to a curable resin composition, a curing method and a sheet prepared by the method. Background technique [0002] The curable resin composition is prepared into a sheet through a curing step. However, in the case of preparing the above-mentioned sheet into a thick film, the curing process time greatly increases. This is because it takes a lot of time to form a polymer network in the initial stage of the thick film curing process. After the specified curing time, the curing speed will increase somewhat, but then the reaction speed will gradually decrease as time goes by. Contents of the invention [0003] The technical problem to be solved in the present invention [0004] An example of the present invention provides a curable resin composition with high conversion rate and improved curing speed. [0005] Still another example of the present invention provides a sheet using the above-mentioned curable resin composition. [0006] Anothe...
