Modified fast growing wood impregnating agent and impregnation high-temperature integrated treatment method

Abstract

The invention relates to a modified fast growing wood impregnating agent and impregnation high-temperature integrated treatment method. The method comprises the following steps: (1) preparing a modified urea-formaldehyde resin impregnating agent; (2) preparing the fast growing wood and treating at a preparation stage; (3) absolutely drying at a high temperature; (4) performing the impregnation and high-temperature integrated treatment; (5) aging, maintaining, inspecting and warehousing. The modified fast growing wood impregnating agent and impregnation high-temperature integrated treatment method has the advantages that: (1) a modified impregnating agent is made into a suspension by adding a nano material on the basis of the conventional urea-formaldehyde resin impregnating agent and ultrasonically stirring, the modification effect of the modified impregnating agent on the aspects such as hardness, abrasion resistance, size stability and the like is better than that of the conventional urea-formaldehyde resin impregnating agent, and the preparation process is simple, moderate in conditions and convenient to operate; (2) the physical and mechanical properties of the fast growing wood such as poplar and cedar can be well improved; the wide application of the fast growing wood can be realized, the consumption of top-grade wood can be reduced, the wood application range can be enlarged, the additional value and technical content of the fast growing wood can be increased, and the optimal application of poor wood can be realized.
