Abstract

PURPOSE

To evaluate the effects of carboxylic and phosphate functional monomers on the bond strength and durability of an acrylic resin joined to a magnetizable stainless steel and its component metals.

MATERIALS AND METHODS

Disk specimens (10 and 8 mm in diameter and 2.5 mm thick) were prepared from SUS XM27 stainless steel, high-purity iron, and chromium metals. The specimens were ground with abrasive paper, and divided into an unprimed control group and 4 groups primed with: 1. Alloy Primer (thione and phosphate); 2. Estenia Opaque Primer (phosphate); 3. Mr. Bond (aliphatic carboxylic acid); or 4. Super-Bond C&B Liquid (aromatic carboxylic anhydride). The disks were bonded with tri-n-butylborane (TBB)-initiated resin, and the shear bond strengths were determined both before and after thermocycling (20,000 X, 5°C - 55°C). The debonded surfaces were analyzed using Xray diffraction (XRD).

RESULTS

The Alloy Primer and Estenia Opaque Primer materials containing 10-methacryloyloxydecyl dihydrogen phosphate (MDP) effectively bonded the steel (30.3 to 32.4 MPa) and iron (33.6 to 34.8 MPa), whereas the four acidic primers bonded chromium (24.6 to 32.3 MPa). X-ray diffractometry detected corroded iron at the debonded interface.

CONCLUSION

Bearing in mind the limitations of the present study, the use of two primers with MDP is recommendable for bonding SUS XM27 steel with TBB-initiated resin. Iron was considered to be a corrosive factor at the adhesive interface, although the associated bonding characteristics were adequate.

摘要

目的

评估羧酸和膦酸官能单体对可磁化不锈钢与树脂结合的粘结强度和耐久性的影响。

材料和方法

从 SUS XM27 不锈钢、高纯铁和铬金属制备直径为 10 和 8 毫米、厚 2.5 毫米的圆盘试件。用砂纸打磨试件，分为未预涂底漆的对照组和用以下物质预涂底漆的 4 个组：1. 合金底漆（硫醇和膦酸）；2. Estenia Opaque Primer（膦酸）；3. Mr. Bond（脂肪族羧酸）；或 4. Super-Bond C&B Liquid（芳香族羧酸酐）。用三丁基硼烷（TBB）引发的树脂将圆盘粘结，在热循环（20,000 次，5°C - 55°C）前后测定剪切粘结强度。使用 X 射线衍射（XRD）分析脱粘表面。
