Embodiment 1

[0016] A method for modifying plantation wood, comprising the following steps:

[0017] (1) Pretreatment: After peeling and sawing the selected fir into the required size specifications, dry it at 50°C-80°C for 8-24 hours, and control the moisture content of the wood to no higher than 25%. , and then microwave treatment for 10 to 30 minutes;

[0018] (2) Modifier equipment: add 100 parts by mass of water, 25 parts by mass of nano-calcium carbonate, 15 parts by mass of nano-silicon dioxide, and then add 1 part by mass of fatty alcohol polyoxyethylene ether into the mixer, and shake the mixture under ultrasonic vibration and Under high-speed stirring with a rotation speed not lower than 6000r / min, treat for 20 to 50 minutes, then add 15 parts by mass of zinc borate, 8 parts by mass of ammonium molybdate, 12 parts by mass of chlorothalonil, 10 parts by mass of sodium octaborate tetrahydrate, bis-octyl 5 parts by mass of base dimethyl ammonium chloride, and stir together evenly t...

Embodiment 2

[0022] A method for modifying plantation wood, comprising the following steps:

[0023] (1) Pretreatment: After the selected poplar is peeled and sawed into the required size specifications, it is dried at 50°C-80°C for 8-24 hours, and the moisture content of the wood is controlled not to be higher than 25. %, then microwave treatment for 10-30 minutes;

[0024] (2) Modifier equipment: Add 75 parts by mass of water, 20 parts by mass of nano-calcium carbonate, 10 parts by mass of nano-silicon dioxide, and then add 0.3 parts by mass of surfactant to the mixer. Under high-speed stirring at 6000r / min, process for 20-50min, then add 10 parts by mass of zinc borate, 2 parts by mass of ammonium molybdate, 8 parts by mass of chlorothalonil, 5 parts by mass of sodium octaborate tetrahydrate, dioctyldimethyl 2 parts by mass of ammonium chloride, and stir together evenly to obtain a composite wood modifier, wherein the nano-calcium carbonate is light calcium carbonate nanoparticles with...

Abstract

The invention discloses a plantation wood modification processing method including steps of preliminary selection, drying and microwave processing; preparation of a modification agent; preparation of a modification solution; vacuum impregnation and post drying. The beneficial effect is that through use of microwave treatment, the permeability of plantation wood is improved, the modification processing effect is improved, the processed wood has flame retardant, smoke suppression, anticorrosive, moth-proofing, color distortion preventing, good erosion resistance and other advantages, and the surface hardness, wear resistance, impact strength, waterproof property and the like are significantly improved, so that the application effect and fields of the plantation wood are well improved, and the plantation wood modification processing method has the very high practical value and promotion prospects.

Description

technical field [0001] The invention relates to the technical field of wood treatment, in particular to a modification treatment method for plantation forest wood. Background technique [0002] With the continuous development of science and technology and the continuous improvement of people's living standards, wood is favored by people based on its characteristics of health, greenness, pollution-free, and renewable; It is shrinking year by year, and timber resources, especially high-quality timber resources, are increasingly in short supply. The raw material structure of the wood processing industry has changed from the original natural forests to artificial forests, secondary forests, and small-diameter timber. However, the material properties of artificial forests are poor, soft in quality, easy to dry and shrink when wet, and poor in dimensional stability, etc., which will greatly limit the use effect and application fields of artificial forest trees. Contents of the i...
