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 comprising a combination of (a) a member 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 and (b) a member selected from the group consisting of an organic acid salt and an inorganic acid salt 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 organic acid salt is a member selected from the group consisting of calcium acetate, zinc acetate, aluminum acetate, and magnesium acetate.
- 3. A method according to claim 1, wherein the inorganic acid salt is a member selected from the group consisting of magnesium sulfate, aluminum sulfate, zinc sulfate, copper sulfate, ferrous sulfate, ferric sulfate, calcium chloride, zinc chloride, magnesium chloride, alum, calcium primary phosphate, magnesium primary phosphate, zinc primary phosphate, ammonium chloride, aluminum nitrate, aluminum chloride, and ammonium sulfate.
- 4. 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.
- 5. 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.
- 6. 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).
- 7. A two-part adhesive comprising an aqueous synthetic resin emulsion and a gelling agent comprising a combination of (a) a member 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 and (b) a member selected from the group consisting of an organic acid salt and an inorganic acid salt.
- 8. A two-part adhesive according to claim 7, wherein the organic acid salt is a member selected from the group consisting of calcium acetate, zinc acetate, aluminum acetate, and magnesium acetate.
- 9. A two-part adhesive according to claim 7, wherein the inorganic acid salt is a member selected from the group consisting of magnesium sulfate, aluminum sulfate, zinc sulfate, copper sulfate, ferrous sulfate, ferric sulfate, calcium chloride, zinc chloride, magnesium chloride, alum, calcium primary phosphate, magnesium primary phosphate, zinc primary phosphate, ammonium chloride, aluminum nitrate, aluminum chloride, and ammonium sulfate.
