Description
Technical field
The invention belongs to glued board technical field, and in particular to a kind of glued board with good mildew and insect proof performance.
Background technology
Glued board is to be peeled into veneer or by flitch slicing into veneer by juggle, then three layers with adhesive gluing or
The board-like material of multilayer, generally uses odd-level veneer, and form the orthogonal gluing of machine direction of adjacent layer veneer.It is glued
Plate is one of furniture common used material, is a kind of wood-based plate.
Because glued board main material is timber, and timber is during prolonged use, especially in low temperature humidity
Worked long hours under larger environment, easily corroded by mould or worm ant, destroy laminated structure, reduce the physical of glued board
Can, shorten the service life of glued board；In existing method, the mildew and insect proof processing to glued board mainly uses antimicrobial impregnated
To improve the antibiotic property of glued board, still, existing antiseptic is in the effect to mould, worm ant with poisoning, while also to people
Body health, surrounding environment produce larger threat, also, using handling timber by the way of dipping, impregnating agent consumption greatly, cost
Height, meanwhile, wood internal is penetrated into, wood internal structure can be destroyed to a certain extent, wood performance is reduced.
The content of the invention
The purpose of the present invention is that there is provided a kind of glued board with good mildew and insect proof performance the problem of being directed to existing.
The present invention is achieved by the following technical solutions：
A kind of glued board with good mildew and insect proof performance, the glued board with good mildew and insect proof performance is three layers of poplar
Wood plywood, is coated after adhesive by surface using surface treated three pieces of board using poplar boards, is bonded together, through overheat
Pressure sizing is made, and the adhesive uses semicarbazides modified starch adhesive；The surface treated board using poplar board is specifically handled
Method is：
（1）Board using poplar board is dipped into the sodium carbonate liquor that mass fraction is 5-8%, is heated to 60 DEG C, treats that board using poplar board is aqueous
Rate is reached after 80-88%, is taken out, after surface is dried, and is placed, stand-by；
（2）By step（1）Board using poplar board after processing is put into vacuum metal container, and helium is passed through into vacuum metal container,
Helium intake be vacuum metal container volume 30-35%, into vacuum metal container insert an aluminium bar, the aluminium bar with
Vacuum metal container is not contacted, and board using poplar board is positioned between aluminium bar and vacuum metal container inner wall, in aluminium bar and vacuum gold
Belong to and 400-450V DC voltages are added on container inner wall, handle 3-5min, then take out；
（3）By step（2）The board using poplar board of middle processing is immediately placed in after taking out in the poly-vinyl alcohol solution that mass fraction is 8%, so
Add the cerium chloride of poly-vinyl alcohol solution quality 0.025% immediately afterwards, ultrasonically treated 2.2-3min then takes out board using poplar board, table
Face is cleaned using deionized water, drying to constant weight, you can.
Further, described ultrasonically treated, processing power is 500W, and frequency is 30kHz.
Further, the board using poplar board thickness is 1.5-2mm.
Further, the adhesive usage amount is 140-160g/m2.
Further, the semicarbazides modified starch adhesive preparation method is：Tapioca is carried out after normal temperature gelatinization, obtained
Mass fraction is 30% starch gelatinization liquid, and the acrylamide performed polymer of its weight 0.5% is added into starch gelatinization liquid, is heated to
80 DEG C, then insulation 30s adds the semicarbazides of starch gelatinization liquid quality 4%, is stirred 2 hours, produced with 3000r/min rotating speeds.
The present invention has advantages below compared with prior art：The present invention is by the processing to board using poplar board surface, especially
By its step（2）Processing, can effectively make its surface active, board using poplar board surface produces substantial amounts of free radical, can
More preferable grafting polyvinyl alcohol, meanwhile, have also combined a certain amount of rare earth element so that its can closely with board using poplar board table
Face is combined, and is formed one layer of fine and close protecting film, board using poplar board surface is hedged off from the outer world, thus, it is possible to significantly improve
To the protective of board using poplar board, while the adhesiveness improving its interface polymer, also, due to step（2）Place
Reason, the nutritional ingredient that can be destroyed needed for the mould moth of board using poplar board top layer so that board using poplar board surface texture cell is densified,
The environment that mould, moth survive on board using poplar board top layer is eliminated, the strong safeguard procedures of glued board second have been become,
The two collective effect, can significantly improve the mildew and insect proof effect of glued board；The present invention by using semicarbazides modified starch adhesive,
Because semicarbazides has the reactivity of height, when importing in amylan, occurs strong cross-linking reaction so that in amylan
Active group be significantly improved, it is anti-to play crosslinking by the active group on active group in amylan and board using poplar board surface
Should, good bonding strength and water resistance are formed after solidification.
