Synthetic example 1

[0223] The following were mixed to obtain a mixture: 97 parts by mass of n-butyl acrylate (manufactured by Nippon Catalyst Co., Ltd.), 3 parts by mass of acrylic acid (manufactured by Nippon Catalyst Co., Ltd.), 0.05 parts by mass of Irgacure 907 (manufactured by Nagase Sangyo Co., Ltd.), and ethyl acetate 200 parts by mass. Next, ultraviolet rays were irradiated to this mixture for 4 hours, and the adhesive resin A (acrylic adhesive A) which is an acrylic copolymer was produced. The weight average molecular weight of binder resin A was about 700,000. The obtained binder resin A has an SP value in the range of 7 to 10.5.

Embodiment 1

[0225] 100 parts by mass of the binder resin A and 567 parts by weight of ethyl acetate as a solvent were mixed. The following were mixed and processed into a film: 100 parts by mass of binder resin A (wherein, 567 parts by mass of ethyl acetate as a solvent was blended together with binder resin A), 110 parts by mass of GAP4006 (glycidyl azide polymer, manufactured by NOF Corporation), N-2-(aminoethyl)-3-aminopropylmethyldimethoxysilane as a silane coupling agent having an amino group (KBM-602 manufactured by Shin-Etsu Chemical Co., Ltd.) 0.001 parts by mass, 2 parts by mass of tripropylamine (tri-n-propylamine) as a tertiary amine, 2-isopropylthioxanthone (DKSH Japan Co., Ltd.) as a photosensitizer IPX) 3.5 parts by mass, and N,N,N',N'-tetraglycidyl-1,3-benzenedi(methanamine) as a crosslinking agent (E-AX toluene manufactured by Soken Chemical Co., Ltd. 5% liquid) 0.5 parts by mass. The film was heated at 110° C. for 5 minutes to remove ethyl acetate as a solvent. This wa...

Embodiment 2～14 and comparative example 1～6

[0229] As shown in the following Tables 1 and 2, except that the types and amounts (units are parts by mass) of the compounding components were changed, a gas generating material was obtained and a micropump was produced in the same manner as in Example 1. In addition, in Examples 2-14, the silane coupling agent which has an amino group was used. In Comparative Examples 1, 2, 4, and 6, a silane coupling agent not having an amino group was used. In Comparative Examples 3 and 6, no silane coupling agent was used.

[0230] In addition, the kind of the silane coupling agent used is as follows.

[0231] N-2-(aminoethyl)-3-aminopropylmethyldimethoxysilane (KBM-602 manufactured by Shin-Etsu Chemical Co., Ltd.)

[0232] N,N-bis[(3-trimethoxysilyl)propyl]ethylenediamine (manufactured by Gelest)

[0233] 3-Aminopropyltrimethoxysilane (KBM-903 manufactured by Shin-Etsu Chemical Co., Ltd.)

[0234] 3-Aminopropyltriethoxysilane (KBE-903 manufactured by Shin-Etsu Chemical Co., Ltd.)

Abstract

The present invention provides a gas generating material having high adhesiveness to a member to be bonded and having a large amount of gas generated per unit time even if it further contains a silane coupling agent. The gas generating material according to the present invention contains a binder resin, a gas generating agent which is an azo compound or an azide compound, and a silane coupling agent having an amino group.

Description

technical field [0001] The present invention relates to a gas generating material and a micropump provided with the gas generating material. Background technique [0002] In recent years, analysis devices using microfluidic devices have begun to be used as analysis devices that are small in size and excellent in portability. In an analysis device using the microfluidic device, liquid feeding, dilution, concentration, analysis, and the like of a sample can be performed in the microchannel. [0003] In the microfluidic device described above, a micropump is provided for liquid feeding of a sample and the like in the microchannel. For example, Patent Document 1 below discloses a micropump using a photoresponsive gas generating material (adhesive composition) containing a photoacid generator and an acid-stimulating gas generating agent. In addition, Patent Document 1 also discloses a photoresponsive gas generating material in which a photoacid generator is mixed with a binder ...
