Abstract
Preservative compositions for wood products are described. The compositions include at least one boron-containing material, such as but not limited to boric anhydride, and at least one silane-containing material, such as but not limited to methyltrichlorosilane. Optionally, at least one solvent, such as tetrahydrofuran, pentane, or water, may also be employed in the compositions. The compositions impart protection to the treated wood products, especially damage caused by exposure to water and insects.
Claims20
A penetrating solution comprising:
- at least one trichlorosilane material;
- at least one hydrocarbon solvent to penetrate and diffuse into a material contacted by the penetrating solution.
A penetrating composition comprising:
- at least one liquid trichlorosilane material;
- and
- at least one liquid hydrocarbon solvent mixed with the at least one liquid trichlorosilane material to form the penetrating composition to penetrate and diffuse into a material contacted by the penetrating composition.
A penetrating composition consisting of:
- at least one chlorosilane material;
- and
- at least one hydrocarbon solvent containing pentane, said at least one hydrocarbon solvent being mixed with the at least one chlorosilane material to form the penetrating composition to penetrate and diffuse into a material contacted by the penetrating composition.
A penetrating solution comprising:
- at least one trichlorosilane material;
- and
- at least one hydrocarbon solvent containing hexane, said at least one hydrocarbon solvent being mixed with the at least one trichlorosilane material to form the penetrating solution to penetrate and diffuse into a material contacted by the penetrating solution.
A penetrating composition comprising:
- at least one chlorosilane material;
- and
- at least one hydrocarbon solvent containing heptane, said at least one hydrocarbon solvent being mixed with the at least one chlorosilane material to form the penetrating composition to penetrate and diffuse into a material contacted by the penetrating composition.
A liquid composition comprising:
- a trichlorosilane material;
- and
- a hydrocarbon solvent.
A penetrating composition comprising:
- a trichloromethylsilane material;
- and
- a hydrocarbon solvent.
A liquid composition consisting of:
- a chlorosilane material;
- and
- pentane.
A liquid composition consisting of:
- a chlorosilane material;
- and
- hexane.
A liquid composition consisting of:
- a chlorosilane material;
- and
- heptane.
A penetrating composition comprising:
- a chlorosilane material;
- and
- one hydrocarbon solvent, wherein the penetrating composition is applied as a liquid to penetrate and diffuse into a material contacted by the penetrating composition.
A penetrating solution consisting of:
- at least one chlorosilane;
- and
- at least one hydrocarbon alkane solvent that is liquid at room temperature to penetrate and diffuse into a material contacted by the penetrating composition.
A method for treating a wood product, said method comprising the steps of:
- providing a solution comprising at least one chlorosilane material and at least one hydrocarbon solvent;
- contacting an untreated wood product with the solution and penetrating and diffusing the at least one chlorosilane material into the wood product;
- and
- wherein the at least one hydrocarbon solvent contains at least one of pentane, heptane, hexane, or combinations thereof.
A method for treating a wood product, said method comprising the steps of:
- providing a composition comprising at least one chlorosilane material and at least one hydrocarbon solvent containing heptane;
- and
- contacting an untreated wood product with the composition and penetrating and diffusing the at least one chlorosilane material into the wood product.
A method for treating a wood product, said method comprising the steps of:
- providing a liquid composition comprising at least one chlorosilane material and at least one hydrocarbon solvent;
- and
- contacting an untreated wood product with the liquid composition, wherein the wood product is contacted with the liquid composition for a sufficient period of time for the at least one chlorosilane material to penetrate the surface of the wood product to a sufficient depth.
