[0095] Synthesis of α-methylstyrene-group-containing oligomers (AMSPU) >

[0096] 120.60 g of TMI and 600.00 g of JEFFAMINE (trademark) D2000 were mixed and reacted at room temperature for one day and one night without temperature adjustment. Confirmed by the results of IR spectrophotometry, the wavenumber is 2,265cm -1 The peak caused by the isocyanate disappears, and the reaction is concluded. In this way, α-methylstyrene-group-containing oligomers (AMSPU) are obtained.

[0097] Initiator >

[0098] Materials used for the initiators are shown in Table 1. Triethylborane:1,6-hexa 35% CX-100 solution of methylenediamine complex (TEB / HMDA / CX-100). Weigh 33.90 g TEB / HMDA / CX-100, 62.30 g AMSPU, 3.60 g TS 720 and 0.20 g M 460 in a 200-mL glass bottle, and use "Awatori rentarō" ARE-500 (Thinky Company, Chiyoda-ku, Tokyo, Japan) (Planetary mixer manufactured by Thinky Corporation, Chiyoda-ku, Tokyo, Japan)) was stirred at 2,000 rpm for 2 minutes to obtain an initiator.

Abstract

A two-part adhesive that enables adhesion in a wide temperature range near room temperature and exhibits an excellent adhesion strength on a poorly-adhesive substrate including a silicone rubber or the like. In some embodiments, the two-part adhesive includes: a main agent including phenoxyethyl methacrylate and tetrahydrofurfuryl methacrylate; and an initiator including an organoborane; wherein the main agent includes the phenoxyethyl methacrylate at 60 to 95% by mass with reference to a mass of a polymerizable component.

Description

technical field [0001] The present disclosure relates to binary adhesives and structures including cured materials thereof, and in particular to reactive binary adhesives for poorly adhering substrates such as substrates including silicone rubber and the like. Background technique [0002] There is a need for efficient and effective means of adhering poorly adhering substrates, such as silicone rubber, by adhesives. [0003] In the case of adhering such poorly adhesive substrates, surface treatments such as flame treatment, ITRO treatment, corona discharge, plasma treatment, ozone or acid oxidation, or sputter etching are often required. Although primers comprising high surface energy materials can be used to cover the surface of poorly adhering substrates, the surface treatments described above are sometimes required in order for the primer to adhere adequately. In this way, adhesion of poorly adhesive substrates often requires complex and expensive treatments, and even wh...
