Embodiment Construction
[0014] The technical solutions of the present invention will be further described below in conjunction with specific preferred embodiments.
[0015] A method for producing modified wood containing nano-alumina, comprising the following steps:
[0016] (1) Wood pretreatment: After peeling and sawing the log into required size specifications, dry it at 50°C-80°C for 8-24 hours, and control the moisture content of the wood to 8%-25%. Then microwave treatment for 10-30 minutes; wherein, the log is suitable for any wood, including poplar, birch, nanmu, eucalyptus, fir, pine and the like.
[0017] (2) Prepare wood modifier: Add 15-25 parts by mass of nano-alumina, 2-6 parts by mass of polyethylene glycol and 0.5-1 part by mass of aluminum-titanium composite coupling agent OL-AT1618 into the mixer, and then Add 300-450 parts by mass of distilled water, start the agitator and stir at a high speed of 3000-6000r / min for 10-50 minutes, then add 10-15 parts by mass of disodium octaborate...
