Abstract
The specification discloses a borate microemulsion product. In one embodiment, the borate microemulsion includes from about 24 to about 32 weight percent emulsified sodium pentaborate; and from about 24 to about 32 weight percent particulate boric acid suspended therein. The microemulsion has a density of about 9.5 to about 10.5 pounds per gallon at about room temperature. In certain embodiments, the microemulsion has a viscosity of about 1200 to about 1520 at a temperature of from about 66° F. to about 70° F. In certain other embodiments, microemulsion has a viscosity of about 1000 to about 3000 at a temperature of from about 70° F. to about 75° F.
Claims23
A method for making a borate microemulsion, the method comprising the steps of:
- mixing one part, by weight, acidic borate with from about 0.6 to about 1.4 parts, by weight, alkali borate and from about 1.5 to about 3 parts, by weight, water to form a first mixture;
- reacting the first mixture at a temperature of from about 32° F. to about 212° F. to provide a first reaction product which comprises emulsified sodium pentaborate;
- and
- mixing the first reaction product with an additional from about 0.5 to about 4 parts, by weight, acidic borate and from about 0.5 to about 2 parts, by weight, water to provide a second product which comprises emulsified sodium pentaborate and particulate boric acid suspended therein
- wherein the acidic borate comprises a borate selected from the group consisting of orthoboric acid, metaboric acid, boric oxide, and mixtures thereof and
- wherein the alkali borate comprises at least a sodium borate.
A method for making a borate microemulsion, the method comprising the steps of:
- mixing one part, by weight, boric acid with from about 0.6 to about 1.4 parts, by weight, sodium tetraborate and from about 1.5 to about 3 parts, by weight, water to form a first mixture;
- reacting the first mixture at a temperature of from about 40° F. to about 100° F. to provide a first reaction product which comprises emulsified sodium pentaborate;
- and
- mixing the first reaction product with an additional from about 0.5 to about 4 parts, by weight, boric acid and from about 0.5 to about 2 parts, by weight, water to provide a second product which comprises emulsified sodium pentaborate and particulate boric acid suspended therein.
A method for making a borate microemulsion, the method comprising the steps of:
- mixing one part, by weight, alkali borate with from about 1 to about 15 parts, by weight, acidic borate and from about 1 to about 20 parts, by weight, water to form a mixture;
- and
- reacting the mixture at a temperature of from about 32° F. to about 212° F. to provide a reaction product which comprises emulsified sodium pentaborate and particulate boric acid suspended therein
- wherein the acidic borate comprises a borate selected from the group consisting of orthoboric acid, metaboric acid, boric oxide, and mixtures thereof and
- wherein the alkali borate comprises at least a sodium borate.
