Abstract

The invention provides a soaking solution for enhancing the waterproofness of wood. The soaking solution is prepared from the following raw materials: water, corn starch or bentonite, polyving akohol or ethyl alcohol, E1-level urea resin rubber powder or E1-level melamine urea resin rubber powder, and a defoamer. The method also provides a preparation method of the soaking solution. The method comprises the following steps: mixing part of water with corn starch or bentonite to obtain a corn starch or bentonite mixed liquid, mixing the rest water with the polyving akohol or ethyl alcohol to obtain a polyving akohol or ethyl alcohol solution, adding the corn starch or bentonite mixed liquid into the E1-level urea resin rubber powder or E1-level melamine urea resin rubber powder, adding all the rest mixed liquid, mixing, and adding the defoamer. The invention also provides application of the soaking solution. The soaking solution provided by the invention has high bonding performance; the resin rubber powder can be fully fused with the water, and when the wood is soaked in the rubber solution, the rubber solution diffuses into the cells of the wood and are fully bonded with the walls of the cells, so that the capacity of the wood is increased, and the effects of enhancing hardness, corrosion prevention, insect prevention, moisture prevention, deformation prevention and the like can be realized.

Description

technical field [0001] The invention relates to the technical field of wood modification, in particular to an impregnating solution for wood reinforced waterproofing, a preparation method and application. Background technique [0002] In order to expand the application range of artificial forest timber and improve the economic value of artificial forest timber, people use various methods to modify the artificial fast-growing forest timber. Among them, wood impregnation refers to soaking wood in a water-soluble low-molecular-weight resin solution. The resin diffuses into the wood cell wall to increase the volume of the wood, then dries to remove moisture, and finally heats the wood modification technology to cure the resin. The wood impregnation process is divided into two stages: impregnation and drying and curing: the impregnation stage generally adopts vacuum pressure treatment, and the impregnation liquid usually uses phenolic resin, urea-formaldehyde resin, furfuryl alco...
