Disclosed is a process for making an animal blood adhesive and the resulting adhesive composition. The adhesive is made by adding to fresh, whole animal blood, without dewatering the blood, an anticoagulant and a preservative. Lime is then added to the anticoagulated, preserved blood, and the pH is adjusted to between about 9 and about 11. A curing agent (such as potassium silicate, sodium silicate and aluminum dihydrogen phosphate) and ammonia are then added to the mixture to yield the animal blood adhesive. The adhesive can be made from any animal blood, such as bovine, porcine, or avian blood. The resulting adhesive is useful for adhering wood-based products, such as plywood and particle board. |
