Abstract
Official abstract text for this publication.
The object of the present invention is to provide a hot melt adhesive which is less likely to cause stringing, and has excellent thermal stability and adhesion, in particular adhesion to a paper material. The present invention relates to a hot melt adhesive comprising: (A) an olefin-based polymer, (B) a butyral resin, (C) at least one selected from the group consisting of a fatty acid and a derivative thereof, and (D) a tackifier resin.
First claim
Opening claim text (preview).
The invention claimed is: 1. A hot melt adhesive consisting of: (A) a polymer mixture of (1) copolymer of ethylene and 1-octene and/or copolymer of ethylene, propylene, and 1-butene and (2) maleic acid modified olefin-based polymer and/or epoxy group modified olefin-based polymer, (B) a butyral resin, (C) a fatty acid and a derivative thereof selected from the group consisting of salad oil, corn oil, soybean oil, epoxidized soybean oil, sesame oil, linseed oil, olive oil, lettuce oil, fish oil, butter, lard, castor oil, grease, engine oil, cutting oil, and mixtures thereof, (D) a tackifier resin, (E) a wax, and (F) optionally, a stabilizer and/or additives. 2. The hot melt adhesive according to claim 1 , wherein the derivative of the fatty acid comprises castor oil and/or hardened castor oil. 3. The hot melt adhesive according to claim 1 , wherein the fatty acid and a derivative thereof is a fluid at temperatures of about 20 to 26° C. 4. A paper product comprises the hot melt adhesive according to claim 1 .
