Abstract
A process uses a water repellant material in order to enhance the water resistance of composite. The process begins with a saturated vegetable or animal fat triglyceride having a low iodine value. The triglyceride is melted to form a sprayable liquid. The sprayable triglyceride and a bonding agent are applied to the fibrous materials, preparatory to a press binding. Then, the sprayed fibrous material is subjected to a hot press cycle in order to form a bonded fibrous composition. The low Iodine Value triglyceride may be selected from a group including hydrogenated vegetable oil, palm oil, stearine, winterized low IV fractions, soy stearine, animal fat, hydrogenated animal fat, and fractionated fats or blends of these materials.
Claims15
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.
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.
