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 for an inorganic material including a copolymer (A) containing an unsaturated (poly) carboxylic acid (anhydride) (a1) and a (meth) acrylic acid alkyl (2 to 30 alkyl carbon atoms) ester (a2) as a constituent monomer; and an aqueous adhesive for an inorganic material (X) including the adhesive improver (J), 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 (X) comprising: an adhesive improver (J) comprising a copolymer (A) containing an unsaturated monocarboxylic acid and/or an unsaturated polycarboxylic acid and/or an unsaturated polycarboxylic acid anhydride (a1) and an acrylic acid alkyl ester or a methacrylic acid alkyl ester (a2) as a constituent monomer, the alkyl group having from 2 to 30 carbon atoms, a saccharide (B) that is selected from the group consisting of xylitol, sorbitol, mannitol, maltitol, lactitol, erythritol and any proper combination thereof, a polycarboxylic acid (C) of 4 to 24 carbon atoms and water. 2. The aqueous adhesive of claim 1 , wherein a weight ratio [(a1)/(a2)] of the (a1) and (a2) in a constituent monomer is 40/60 to 99/1. 3. The aqueous adhesive of claim 1 , wherein the (a1) is one selected from the group consisting of acrylic acid, methacrylic acid, maleic acid and maleic anhydride. 4. The aqueous adhesive of claim 1 , wherein a weight-average molecular weight of the copolymer (A) is 6,000 to 100,000. 5. The aqueous adhesive of claim 1 , wherein a weight ratio [(B)/(C)] of the saccharide (B) and polycarboxylic acid (C) is 25/75 to 75/25. 6. The aqueous adhesive of claim 1 , wherein the weight of the copolymer (A) is 1 to 20 wt. % based on the total weight of the saccharide (B) and polycarboxylic acid (C). 7. An adhesive article of an inorganic material bonded with a cured material of the aqueous adhesive (X) of claim 1 . 8. An aqueous adhesive for an inorganic material (X) comprising: an adhesive improver (J) comprising a copolymer (A) containing an unsaturated monocarboxylic acid and/or an unsaturated polycarboxylic acid and/or an unsaturated polycarboxylic acid anhydride (a1) and an acrylic acid alkyl ester or a methacrylic acid alkyl ester (a2) as a constituent monomer, the alkyl group having from 2 to 30 carbon atoms, a saccharide (B) that consists of a dextrin, a polycarboxylic acid (C) of 4 to 24 carbon atoms and water.
