Abstract
The preparation of beehives from a synthetic resinous material which is acceptable to the bees, which is not attacked by vermin, and which exhibits the requisite physical properties to provide a desirable beehive is accomplished by assembling the hives from molded urethane foam panels, the urethane foam being formulated so as to produce a product which is not rejected by the bees and which does not make the bees nervous or otherwise interfere with their normal habits in secreting honey in said beehive.
Claims4
A beehive constructed of panels molded with wall thicknesses of between about one-half inch and two inches, of closed cell polyurethane foam having a density of between 4 and 50 pounds per cubic foot, namely:
- a molded bottom, a molded cover and molded wall panels, and means for securing said panels to form a beehive which is acceptable to a bee colony, said foam having been formed by foaming a composition including:
- (a) at least one polyol;
- (b) at least one amine catalyst;
- (c) at least one foaming agent;
- and
- (d) at least one isocyanate;
- and wherein the amine catalyst is selected from the group consisting of amines exhibiting a sufficiently low vapor pressure in the foamed polyurethane product that the foamed polyurethane beehive is acceptable to the bees.
