of the invention further include peach branch (with the usual fruit tree branch trimmed or fall naturally Bifurcation, without individually felling, therefore at low cost), since to compare trunk much greater for very thin peach branch specific surface area, it is present in The natural gum (coming from peach branch) of surface and subsurface is very rich, according to related research, peach branch wooden structures and branch table It is intradermal that rich in compositions such as galactolipin, rhamnose, phlorose aldehydic acid, adhesivity is high, moisture content is high, hydrophily is high, good toughness, but Adhesive strength is slightly lower, and using biotechnology, their cell wall is decomposed using cellulase, on the one hand obtains more, living Property stronger adhesivity substance, be on the one hand polysaccharide (cell wall, cellulose, lignin etc.) by stable cell wall breakdown, be Later period tackified finish and prevent insect pest and addle (timber easily it is infested and addle on the one hand since it is in neutral environment, another party Face containing sugared object provides basic nutrients due to cell wall etc. for microorganism and polypide) it lays a solid foundation.(2) work as work Property sticky matter be sufficiently precipitated after, be added as the wooden original slurry material of matrix, silicate microbial bacterial

substance for promoted paper it is wet strong when strong (binding force the is strong) intensity of viscosity it is low (tearable), thus present invention employs do not have to use in routine techniques using liquid acetaldehyde as the cyanurotriamide modified low of raw material Aldehyde Lauxite carries out that supplement is glued, and the binding force of this adhesive and cellulose changes compared to the melamine in routine techniques Property Lauxite want poor, and the paper embrittlement phenomena after gluing is obvious, thus while being used alone does not have use value, but with this The peach branch organic gel of invention forms good and apparent complementary effect when being used cooperatively, and this material itself and peach branch are organic Glue can dissolve each other, thus reach few low aldehyde effect using chemical organic gel, and what worth one said is to be different from formaldehyde room temperature Down it is gaseous state, generally wants use soluble in water, is liquid under acetaldehyde room temperature, does not have to addition aqueous medium in the present invention, thus it is dirty Dye and consumption reduce and paper degree of purity is more preferable, improves environmental-protecting performance.(5) among other advantages, the present invention is due to having both The characteristic of toughness glue and brittleness glue, thus the paper produced also has that unit G fineness is thin, soft, color is good, toughness and resistance to Mill property is strong, has unique resilience, has stronger vertical and horizontal intensity, and stable uniform, moisture absorption is breathed freely and the skill of antibiotic rate Art effect, with technical purpose perfect matching of the invention.Therefore the
