Wood composition containing a 24 to 50 C alkene (alpha-olefin), use of said alkenes for rendering raw wood materials water repellent, and method for the production of wood materials

摘要

Disclosed is a wood composition, comprising wood raw materials from lignocelluloses in the form of chips, strands or fibers, and olefins with an average of 24 to 50 carbon atoms, wherein more than 50 mol% of the olefins are alpha-olefins, the olefins have a maximum of the distribution between 24 and 40 carbon atoms, and based on the dry weight of the wood materials, 0.1 to 5 wt% olefins and paraffin waxes, such that there is a minimum of 0% paraffin waxes and , where present, said paraffin waxes are in the form of long-chain saturated hydrocarbons wherein the weight ratio of the paraffin waxes to the olefins is 1:30 to 20:1, are contained in the wood material composition.
