Straw particle board employing bark powder modified phenolic resins as adhesives

A straw particle board employing bark powder modified phenolic resins as adhesives adopts straws as main raw materials and woodworking fragment wood shavings as secondary materials. The particle board is characterized in that the adhesives of the pressed straw particle board employ the bark powder modified phenolic resins, a large amount of renewable wood processing remained bark powders are adopted to replace parts of petrochemical phenols, the phenols are employed to directly activate the bark powders, the bark powders are applied to preparation of phenolic resin adhesives, and operation is simple. In a gluing process, CH3Si (OH) 3 organic silicon liquor with low cost is adopted to modify the adhesives so as to enable the adhesives to easily moisten, penetrate and diffuse on the surfaces of the straws, thereby being favorable for glue joint of the straws. Simultaneously, interfaces of the straws are modified so as to enable the bark powder adhesives to be applied to production of the straw particle board. The straw particle board produced by adopting the adhesives has the advantages of attaching importance to effective usage of biological materials, having low product manufacturing cost, fine performance, strong operability and bringing remarkable ecological benefits and environmental benefits after being popularized.
