2200 Pa。
Further, it sprayed in timber, painted, is glued, after grafting processing, using one step hydro thermal method in wood substrate
Upper structure super-drainage structure：
0.5-0.7 parts of deionized waters and 0.05-0.1 parts of concentrated nitric acids, magnetic agitation 10- are added into 15-17 parts of absolute ethyl alcohols
15min is slowly added to 5-10 parts of butyl titanates and 5-10 parts of vinyltriethoxysilane, and magnetic agitation 20-25min will
Timber test specimen is put into hydrothermal reaction kettle, and the mixed liquor of preparation is added, 5-6h is kept the temperature in 100-105 DEG C of air dry oven, takes
Go out and dry in the air to room temperature, timber test specimen is put into deionized water and is cleaned by ultrasonic 30-35min, is put into 58-62 DEG C of vacuum drying chamber and does
Dry 5-6h.
The present invention has the following advantages compared with prior art：
（1）Boiling boiling processing is carried out to wood single-plate using sodium hydroxide solution, alkali process can increase the crystallization of wood sample
Degree, alkali process can make timber be easier to relax, this is mainly caused by the dissolution by hemicellulose；Solvent extraction is leachable
Solable matter in timber improves dye liquor permeability, is conducive to the processing such as spray timber, paint, is glued, being grafted.
（2）Using radial compression combination high temperature steaming method, damp and hot-compression processing timber, wood-cellulose microfibrillar angle
Without significant change, wood cell wall cellulose crystallity and crystallite is wide increases is influenced, wood cell by steaming temperature
The generation crystallization of wall matrix or the quasi- crystallization art of cellulose causes the wide increase of crystallite, be conducive to spray timber, paint,
The processing such as glued, grafting.
（3）Plasma modification processing, wood surface and water, diiodo- first are carried out to timber test specimen using air as processing gas
The contact angle of alkane is obviously reduced, and surface free energy increases, and wetability significantly improves, and is handled and is carried using air plasma
The performances such as gluing, grafting between high timber and wood base composite material.
（4）It sprayed in timber, painted, is glued, after grafting processing, being built in wood substrate using one step hydro thermal method
Super-drainage structure, it is possible to increase water drop static contact angle reduces roll angle, and super-hydrophobic timber remains to protect after hydrothermal aging is handled
Higher surface water drop static contact angle is held, the super-hydrophobic timber of hydro-thermal reaction processing has good heat and moisture aging resistance
And acid resistance, the service life of timber can be improved.
