Add agent, but sterol, polypeptide, colloid extracted from cornu caprae hircus etc. is respectively adopted as tackifier, wood glue is extracted from peach branch
The vegetalitas surface adhesion force promotor of (peach gum) as natural nuisance-free, on the one hand takes full advantage of in routine techniques and does not answer
Waste (goat's horn be different from deer horn and ox horn, by the reason of composition in the inner substantially without medical value, cannot be such as deer
Angle, ox horn are equally used as medicine, also due to its geomery is limited, can not be processed as the objects such as craftwork or daily necessity such as horn comb
Part, therefore be typically also directly to be discarded as waste；And peach branch is different from peach trunk there are also other effects, in people day
Often plantation peach during also otherwise it is open close cross trimming branch come maintain peach shape and produce fruit rate, trim the branch to get off
One without used in, also can only waste treatment, but it is in fact also dry equally containing a large amount of Collagen materials abundant with peach in peach branch,
Only because not excessive and go out be inconvenient to pick edible) the natural free of contamination additive source of conduct, not only saved cost but also

In these substances be all water-soluble, small molecule, thus it is good with acrylic based resin binding force of the invention, also easily penetrate into wood
Device surface, thus it is very outstanding as tackifier and matching of the present invention, it is also convenient for brushing the film forming at woodenware surface and mentions film
Self-bonding power and intensity.(5) it is different from leaning on resin itself entirely in conjunction with the organic resins such as the glass fibre in routine techniques and ABS
Internal bond fix, peach gum of the invention, angle glue 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 addition to CF in all compositions of the invention
Outside a small amount of additive such as carbon fiber, aluminium borate and carborundum powder, other compositions are water-soluble substances, on the one hand environmental protection, to people
It is harmless, it is applied widely, it is deployed when on the other hand convenient to use, easy to use, good economy performance.(7) due to self-adhesion of the invention
Even intensity is higher than conventional coating in the prior art in the case where being added to two kinds of colloids (peach gum, angle glue), and the present invention is also
Enough viscosity surplus additions function composition completely immiscible with acrylic based resin of the present invention: it is obviously improved lubrication of the present invention
The CF carbon fiber of property and integral hardness, the aluminium borate for being obviously improved intensity of the present invention, the carbon for being obviously improved wear-resisting property of the present invention
SiClx powder directly improves wearability and lubricity of the invention, and the dicoration for improving coating of the present invention is (translucent
Opaque aluminium borate and silicon carbide existing for multiclass colloid and disperse) with feel (feel as a variety of cured class ambers of colloid and
Hard and stroke gently feel with lubricator bring).Therefore the present invention have specially be suitable for woodenware surface, it is aqueous, do not hurt it is wooden,
