Cellulose nanocrystal that the present invention especially selects is a kind of different from increasing in routine techniques The substance of strong additive glass fibre, this substance is very flexible and durable, intensity are even more than steel product, simultaneously It or effective antioxidant, can hinder the oxidation course on woodenware surface, promote service life of the invention and protect woodenware This plastid.(5) it is different from the complete interior combination for leaning on resin itself in conjunction with the organic resins such as the glass fibre in routine techniques and PMMA Power is fixed, and peach gum of the invention, angle glue and sodium metasilicate are the adhesivity substance of high kinematic viscosity, can effectively increase matrix resin Internal bond, keep internal bond of the present invention stronger, intensity, surface hardness are higher.(6) in all compositions of the invention in addition to Outside a small amount of additive such as CNC Cellulose nanocrystal, titanium dioxide and activated carbon powder, other compositions are water-soluble substances, a side Face ring is protected, harmless to humans, applied widely, is deployed when on the other hand convenient to use, easy to use, good economy performance.(7) due to this Being higher than from adhesion intensity in the case where being added to three kinds of colloids (peach gum, angle glue and sodium metasilicate) for invention is in the prior art normal Coating is advised, the present invention function composition completely immiscible with acrylic based resin of the present invention there are also the addition of enough viscosity surpluses: It is obviously improved the CNC Cellulose nanocrystal of internal bond strength of the present invention and integral hardness, is obviously improved intensity and antibacterial of the present invention The titanium dioxide of performance, the activated carbon powder for being obviously improved self-cleaning property of the present invention and greasy property, directly improve the present invention Wearability and lubricity, and the dicoration for improving coating of the present invention is (impermeable existing for translucent multiclass colloid and disperse Bright titanium dioxide and activated carbon) it (feel and hard as a variety of cured class ambers of colloid and rubs with lubricator bring with feel Sha feel).Therefore the present invention have specially be suitable for woodenware surface, it is aqueous, do not hurt wooden, high adhesion force, high abrasion, surface from The good characteristic of lubrication, texture, there is excellent comprehensive performance.
