Description
Technical field
The invention belongs to glued board technical fields, and in particular to a kind of glued board with good mildew and insect proof performance.
Background technology
Glued board be veneer is peeled into or by flitch slicing at veneer by juggle, then made of adhesive gluing three layers or
The board-like material of multilayer usually uses odd-level veneer, and the orthogonal gluing of the machine direction of adjacent layer veneer is made to form.It is glued
Plate is one of furniture common used material, is a kind of wood-based plate.
Since glued board main material is timber, and timber is during prolonged use, especially in low temperature humidity
It works long hours under larger environment, is 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, antimicrobial impregnated is mainly used to the mildew and insect proof processing of glued board
The antibiotic property of glued board is improved, still, existing antiseptic has the function of poisoning to mould, worm ant, while also to people
Body health, ambient enviroment generate larger threat, also, handle timber by the way of dipping, and impregnating agent dosage is big, cost
Height, meanwhile, wood internal is penetrated into, wood internal structure can be destroyed to a certain extent, reduces wood performance.
Invention content
The purpose of the present invention is for existing problem, provide a kind of glued board with good mildew and insect proof performance.
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 are three
Layer poplar plywood is bonded together after coating adhesive by surface using surface treated three pieces of board using poplar boards, is passed through
It crosses thermocompression forming to be made, the adhesive uses semicarbazides modified starch adhesive；The surface treated board using poplar board is specific
Processing 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, waits for board using poplar board
It after moisture content reaches 80-88%, takes out, after surface is dried, places, for use；
（2）By step（1）Treated, and board using poplar board is put into vacuum metal container, and helium is passed through into vacuum metal container
Gas, helium intake are the 30-35% of vacuum metal container volume, and an aluminium bar, the aluminium bar are inserted into vacuum metal container
It does not contact, board using poplar board is positioned between aluminium bar and vacuum metal container inner wall, in aluminium bar and vacuum with vacuum metal container
400-450V DC voltages are added on canister inner wall, are handled 3-5min, are then taken out；
（3）By step（2）The board using poplar board of middle processing is immediately placed in the poly-vinyl alcohol solution that mass fraction is 8% after taking out
In, the cerium chloride of poly-vinyl alcohol solution quality 0.025% is added immediately after, is ultrasonically treated 2.2-3min, is then taken out poplar list
Plate, surface are cleaned using deionized water, and drying to constant weight, you can.
Further, the supersound process, processing power 500W, frequency 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：After tapioca is carried out room temperature gelatinization, obtain
The starch gelatinization liquid that mass fraction is 30%, the acrylamide performed polymer of its weight 0.5% is added into starch gelatinization liquid, is heated to
80 DEG C, then heat preservation 30s adds the semicarbazides of starch gelatinization liquid quality 4%, with 3000r/min rotating speeds stir 2 hours to get.
The present invention has the following advantages 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 generates a large amount of free radical, can
Better 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 isolated from the outside world, thus, it is possible to significantly improve
Adhesiveness to the protective of board using poplar board, while improving its interface between polymer, also, due to step（2）Place
Reason, can destroy the nutritional ingredient needed for the mould moth of board using poplar board surface layer so that and board using poplar board surface texture cell is densified,
It eliminates mould, the environment that moth survives on board using poplar board surface layer, has become the strong safeguard procedures of glued board second,
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,
Since there is semicarbazides the reactivity of height strong cross-linking reaction occurs so that in amylan when importing 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
It answers, forms good bonding strength and water resistance after solidification.
