Embodiment 1

[0144] The components of Example 1 were taken in parts by mass shown in Table 1, and were mixed at room temperature (25° C.) for 60 minutes using a mixer (device name Tornado high output power type PM-202 (manufactured by AS ONE Co., Ltd.), rotating speed: 100 rpm). Minutes, a photocurable resin composition was prepared, and various physical properties were measured as follows. It should be noted that the detailed preparation amounts are in accordance with Table 1, and all numerical values ​​are expressed in parts by mass.

Embodiment 2～9 and comparative example 1～8

[0146] The photocurable resin compositions of Examples 2 to 9 and Comparative Examples 1 to 8 were prepared in the same manner as in Example 1 using the components taken in parts by mass shown in Table 1 and Table 2, and various physical properties were measured. . It should be noted that the detailed preparation amounts are in accordance with Table 1 and Table 2, and all numerical values ​​are expressed in parts by mass.

[0148] Production of polyisobutylene polymer (a1) having acryloyloxyethoxyphenyl group

[0149] After substituting nitrogen in the container of the 5 L separable flask, 200 mL of n-hexane and 2000 mL of butyl chloride were added, and cooled to -70°C while stirring under a nitrogen atmosphere. Next, 840 mL (9 mol) of isobutene, 12 g (0.05 mol) of p-dicumyl chloride, and 1.1 g (0.012 mol) of 2-picoline were added. After the reaction mixture was cooled to -70°C, 5.0 mL (0.05 mol) of titanium tetrachloride was added to start polymerization. Three...

Abstract

The purpose of the present invention is to provide a photocurable resin composition which can be cured quickly by irradiation with active energy rays such as ultraviolet radiation and which exhibits excellent adhesive strength to an electrolyte membrane that is a poorly adhesive material. Specifically, the present invention provides a photocurable resin composition that contains components (A) to(C). Component (A): A polymer having a polyisobutylene skeleton containing -[CH2C(CH3)2]- units, which has 1 or more (meth)acryloyl groups. Component (B): A radical photopolymerization initiator. Component (C): 1 or more compounds selected from the group consisting of silicone oligomers having 1 or more alkoxy groups and 1 or more (meth)acryloyl groups, silicone oligomers having 1 or more alkoxy groups and 1 or more amino groups, and silane compounds having 1 or more isocyanate groups.

Description

technical field [0001] The present invention relates to a photocurable resin composition that is rapidly cured by irradiation with active energy rays such as ultraviolet rays and has excellent adhesion to an electrolyte membrane, which is a difficult-to-bond material. Background technique [0002] In recent years, fuel cells have attracted attention as a new energy system for automobiles and households. A fuel cell is a power generation device that generates electricity by chemically reacting hydrogen and oxygen. In addition, the fuel cell is a next-generation clean power generation device because of its high energy efficiency during power generation, and the generation of water through the reaction of hydrogen and oxygen. There are four types of fuel cells: solid polymer fuel cells, phosphoric acid fuel cells, molten carbonate fuel cells, and solid oxide fuel cells. Among them, solid polymer fuel cells have a relatively low operating temperature (80 °C) and high power gen...
