Abstract
This invention relates to a mass preparation method of spherical natural color wax beads and according to the invention, the beads have a higher specific gravity than water so that the beads do not flow into the sea and they are biodegradable to fundamentally remarkably reduce marine ecosystem contamination, and it enables mass preparation by significantly improving the previous preparation of spherical natural color wax beads which had difficulties in their mass preparation while using expensive equipment.
Claims11
A method for preparing spherical natural color wax beads, comprising
- 1) a first step of melting wax in a reaction vessel and then defoaming it;
- 2) a second step of adding a pigment and a filler to the reaction vessel which passes through the first step so that a mixture including the wax has a higher specific gravity than 1.0;
- 3) a third step of adding water including a suspension stabilizer to the reaction vessel which passes through the second step and stirring it;
- 4) a fourth step of mixing the reactant which passes through the third step with a cold water to lower the temperature of the mixture below the melting temperature (Tm) of the wax, thereby forming spherical color beads;
- and
- 5) a fifth step of separating from the mixture the spherical color beads which are included in the mixture of the fourth step.
