Abstract
Official abstract text for this publication.
To provide an aqueous adhesive for an inorganic material with excellent adhesiveness to the inorganic material. An adhesive improver (J) for an aqueous adhesive of an inorganic material including a (co) polymer (A) containing an unsaturated (poly) carboxylic acid (anhydride) (al) as a constituent monomer, wherein a weight-average molecular weight of the (co) polymer (A) is 6,000 to 200,000; and an aqueous adhesive for an inorganic material (X) including the adhesive improver (J) for an aqueous adhesive of an inorganic material, a saccharide (B), a polycarboxylic acid (C) having 4 to 24 carbon atoms, and water.
First claim
Opening claim text (preview).
What is claimed is: 1. An aqueous adhesive for an inorganic material, the aqueous adhesive comprising: an adhesive improver (J) comprising a (co)polymer (A) containing an unsaturated monocarboxylic acid and/or an unsaturated polycarboxylic acid and/or an unsaturated polycarboxylic acid anhydride (a1) as a constituent monomer, wherein a weight-average molecular weight of the (co) polymer (A) is from 6,000 to 200,000, a saccharide (B) that is a sugar alcohol, a polycarboxylic acid (C) having 4 to 24 carbon atoms, and water, wherein a weight ratio [(B)/(C)] of the saccharide (B) and polycarboxylic acid (C) is 25/75 to 75/25. 2. The aqueous adhesive of claim 1 , wherein the weight of the (co) polymer (A) is 1 to 20 wt. % based on the total weight of the saccharide (B) and polycarboxylic acid (C). 3. An adhesive article of an inorganic material bonded with a cured material of the aqueous adhesive of claim 1 . 4. The aqueous adhesive of claim 1 , wherein the weight-average molecular weight of the (co) polymer (A) is 8,000 to 100,000. 5. The aqueous adhesive of claim 1 , wherein the sugar alcohol is xylitol, sorbitol, mannitol, maltitol or lactitol. 6. An aqueous adhesive for an inorganic material, the aqueous adhesive comprising: an adhesive improver (J) comprising a (co)polymer (A) containing an unsaturated monocarboxylic acid and/or an unsaturated polycarboxylic acid and/or an unsaturated polycarboxylic acid anhydride (a1) as a constituent monomer, wherein a weight-average molecular weight of the (co) polymer (A) is from 6,000 to 200,000, a saccharide (B) that is selected from the group consisting of xylitol, sorbitol, mannitol, maltitol, lactitol and any proper combination thereof, a polycarboxylic acid (C) having 4 to 24 carbon atoms, and water.
