Claims
- 1. A process for enhancing water resistance and water tolerance of composite boards and structures by a use of water repellant material applied to fibrous plant and wood materials, said process comprising the steps of:a) providing a saturated triglyceride water repellant material having a low iodine value, said triglyceride being selected from a group consisting of vegetable oil and animal fat; b) melting said triglyceride to form a sprayable liquid; c) preparing said melted triglyceride liquid of steps a) and b) for combining with a bonding agent; d) spraying said liquid and bonding agent onto said fibrous materials preparatory to press binding; and e) subjecting said materials of step d) to a hot press cycle in order to form a bonded fibrous composition.
- 2. The process of claim 1 wherein said melted triglyceride liquid and said bonding agent of step c) are blended into a mixture prior to a time when it is applied to said fibrous mixture.
- 3. The process of claim 1 wherein said triglyceride and said bonding agent are separately applied to said fibrous material in step d).
- 4. The process of claim 1 where the low iodine value triglyceride of step a) is selected from a group consisting of hydrogenated vegetable oil, palm oil, stearine, winterized low rv fractions, soy stearine, animal fat, hydrogenated animal fat, and fractionated fats and blends of these materials.
- 5. The process of claim 1 where the low Iodine Value is in a range from about 0 to 70.
- 6. The process of claim 1 where the low Iodine Value is in a range from about 0 to about 30.
- 7. The process of claim 1 wherein the fibrous plant and wood materials are selected from a group consisting of wood, wood fibers, agricultural fibers, agricultural materials, and mixtures of these materials with plastics or polymers.
- 8. The process of claim 1 wherein the water repellant material melted in step b) has a low iodine value with a range of about 0-70 produced by a hydrogenation of a commercial oil or fat, taken from a group consisting of soybean, corn, cottonseed, rape, canola, sunflower, fish, lard, tallow, palm, palm kernel, coconut, crambe, linseed, peanut, and tall oil.
- 9. The process of claim 1 wherein said bonding agent is selected from a group consisting of an adhesive resin, an emulsion of adhesive resin and water, a conjugated triglyceride coadhesive, and combinations thereof.
- 10. The process of claim 1 wherein the bonding agent is taken from a group consisting of urea-formaldehyde, melamineurea-formaldehyde, polyvinyl acetate, phenol formaldehyde, isocyanate, di-isocyanate, resorcinol-phenol-formaldehyde, protein, tannin-formaldehyde, sulfite liquor, conjugated linseed oil, and any combinations of these.
- 11. The process of claim 1 wherein the liquid of claim 1 step b) has a co-adhesive selected from a group consisting of urea-formaldehyde, melamine-urea-formaldehyde, polyvinyl acetate, phenol formaldehyde, isocyanate, di-isocyanate resorcinol-phenol-formaldehyde, protein, tannin-formadehyde, sulfite liquor and conjugated linseed oil and any combinations of these.
- 12. A process for enhancing water resistance and water tolerance of composite boards made of fibrous plant and wood materials, said process comprising:a) providing a water repellant material comprising a saturated triglyceride having a low iodine value; b) melting said water repellant material to place said triglyceride in a sprayable liquid form; c) spraying a combination of said saturated triglyceride of steps a) and melted in step b) and a bonding agent onto said fibrous materials preparatory to press binding; and d. subjecting said materials of step c) to a hot press cycle in order to form a bonded fibrous composition board.
- 13. The process of claim 12 wherein said combination said of triglyceride and said bonding agent of step c) is blended into a mixture before it is sprayed in step c).
- 14. The process of claim 12 wherein said combination of melted triglyceride and said bonding agent are separately and sequentially sprayed onto said fibrous material in step c).
- 15. A process for enhancing water resistance and water tolerance of composite boards and structures by a use of water repellant material applied to fibrous plant and wood materials, said process comprising the steps of:a) providing a saturated triglyceride water repellant material having a low iodine value, said triglyceride being selected from a group consisting of vegetable oil and animal fat; b) melting said triglyceride to form a sprayable liquid; c) spraying said liquid onto said fibrous materials preparatory to press binding; and d) subjecting said materials of step c) to a hot press cycle in order to form a bonded fibrous composition.
