Claims
- 1. A method for bonding two substances together which comprises applying a two-part adhesive comprising an aqueous synthetic resin emulsion adhesive and a gelling agent selected from the group consisting of calcium pantothenate, glycine calcium salt, alanine calcium salt, serine calcium salt, threonine calcium salt, methionine calcium salt, phenylalanine calcium salt, and calcium aspartate to at least one of the substances to be adhered, disposing the substances one on the other, and then contact-pressing them together.
- 2. A method according to claim 1, wherein the aqueous synthetic resin emulsion adhesive and the gelling agent are simultaneously applied to the substances to be bonded in the form of spray.
- 3. A method according to claim 1, wherein the gelling agent is used in the form of a 0.5 to 50% by weight aqueous solution.
- 4. A method according to claim 1, wherein the aqueous synthetic resin emulsion adhesive and the gelling agent are used in the ratio of 100:0.005 to 100:5 by weight (as the solid component).
- 5. A two-part adhesive comprising an aqueous synthetic resin emulsion and a gelling agent selected from the group consisting of calcium pantothenate, glycine calcium salt, alanine calcium salt, serine calcium salt, threonine calcium salt, methionine calcium salt, phenylalanine calcium salt, and calcium aspartate.
- 6. A two-part adhesive according to claim 5, wherein the aqueous synthetic resin emulsion is an aqueous emulsion containing as the main solid component a polymer selected from the group consisting of polyvinyl acetate, vinyl acetate copolymer, polyacrylate, acrylate copolymer, ethylene/vinyl acetate copolymer, polyolefin, styrene/butadiene copolymer, methyl methacrylate/butadiene copolymer, nitrile/butadiene copolymer, polychloroprene, polyisoprene, polyurethane, polyepoxyasphalt, styrene/isoprene copolymer, maleic acid/isoprene copolymer sodium salt, polyvinyl chloride, vinylidene chloride copolymer, polyvinylpyrrolidone, polyvinyl alkyl ether, and phenol-formalin reaction mixture.
