摘要:
An adhesive cement is prepared by coating an aluminosilicate glass ionomer with an acid polymerization inhibitor of pKa between 2-3.5, and then mixing the treated glass with cyanoacrylate monomer and water. The glass is treated by dissolving the acid, typically tartaric, tartronic, malic, maleic or mellitic acid in methanol and adding the glass powder to form a slurry, then evaporating the methanol. In a further embodiment, the water can also contain a polyacid compound such as polyacrylic acid, polyvinyl phosphonic acid, a coploymer of acrylicacid with itaconic acid and/or vinylphosphonic acid, or mellitic, phytic or tannic acid. In use the cyanoacrylate polymerizes to from a binding resin, whilst the ionomer undergoes an acid-base reaction to form a compound which forms a strong adhesive bond with materials such as metals, glasses, vinyl polymers, or dental material.
