Abstract

The glue additive for artificial plate consists of wood dust in 70-100 wt% and talcum powder in 0-30 wt% mixed together. The wood dust has water content below 10 % and fineness below 260/300 mesh, and the talcum powder has water content below 10 % and fineness below 325/400 mesh. The wood dust may be replaced by bamboo dust, stalk powder and other plant powder; and the talcum powder may be replaced by gypsum powder, lime powder or other mineral powder. The glue additive for artificial plate can make the artificial plate possess smoothness, environment friendship and other advantages.

Description

Glue additive for artificial board
Technical field
The present invention relates to tackiness agent, particularly relate to glue additive for artificial board.
Background technology
Along with the quality product of wood-based plate improves constantly, wood-based plate is decorated in indoor and outdoor, furniture manufacturing and building field, has obtained using widely.Traditional the most common manufacturing gluing technique of wood-based plate is at present, in tackiness agent, mixes common edible flour in proportion, and on-the-spot the stirring promptly used, and its objective is: the one, increase the bonding agent viscosity, and can satisfy the spread of veneer roller coating; The 2nd, rise to add and use usefulness as, prevent that plate face drying shrinkage from subsiding; The 3rd,, play the aggregate effect, increase wood-based plate hardness, improve the planeness of wood-based plate; Above traditional technology is made wood-based plate, and gummed adds flour and has serious quality drawback and shortcoming; The one, prove that this type of wood-based plate is moisture-sensitive in use if steep its result through water logging; The 2nd, be timber 3-5 times through the under equal conditions common edible flour water ratio of experiment test, amount, the coefficient of expansion has also increased 3-5 doubly thereupon, and flour density is big in addition, and moisture is difficult for evaporation, has a strong impact on wood-based plate use properties and quality product; The 3rd, because of coefficient of expansion difference, cause the wood-based plate bulge, come unglued, ftracture; The 4th, stable poor after common edible flour makes moist, particularly building template and concrete directly touch, equal in water, to soak the same, under the saturated situation of water ratio, xylon expands, under the internal stress squeezing action, it is together excessive that the flour at wood-based plate edge is carried tackiness agent secretly, causes the building template cracking after coming unstuck; The 5th, summer temp, humidity Yi Shenggao, common edible flour makes moist and easily goes mouldy, and the bonding strength that can make tackiness agent of going mouldy descends 40%, is wood-based plate rimose one of the main reasons; Make wood-based plate gummed interpolation flour in view of above tradition and have quality drawback and shortcoming, we have developed a kind of gummed additive that can replace flour through repeatedly experiment.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of wood-based plate make moist distortion, cracking avoided, and improves the glue additive for artificial board of wood-based panel product quality.
The technical scheme that adopts is:
Glue additive for artificial board by weight percentage, is formed by the solid wood wood powder of 70-100% and the talcum powder mixing and stirring of 0-30%.
Above-mentioned solid wood wood powder water ratio is in 10%, crosses the solid wood wood powder of 260/300 mesh sieve.
Above-mentioned talcum powder water ratio is in 10%, crosses the talcum powder of 325/400 mesh sieve.
Above-mentioned solid wood wood powder can be substituted by bamboo, straw and vegetable material powder.
Above-mentioned talcum powder can be substituted by terra alba, lime powder and other mineral powder.
The making method of glue additive for artificial board comprises:
1, select for use deciduous tree linden, poplar, elm, toothed oak, the birch of nontoxic, free from extraneous odour, the wood of Qu Mu to cut (not containing softwood tree), the artificial seasoning water ratio reaches in 10%, through grinding to form the solid wood wood powder of 260/300 mesh sieve.
2, buy national standard talcum powder 325/400 order, in the artificial seasoning water ratio 10%.
The solid wood wood powder and the talcum powder that 3, will take by weighing by weight percentage, through sterilization, mixing and stirring.
Glue additive for artificial board of the present invention, solid wood wood powder in the composition is to adopt the solid wood wood of deciduous tree to cut to grind to form the solid wood wood powder, it is microscler microparticle that grinding technics can keep the granule of solid wood wood powder, replace flour, the adding of this wood powder filled effect, tenacious and persistent will and pulling force and the experiment proved that and all be better than flour.The solid wood wood powder is similar goods and materials with the veneer that wood-based plate uses, and drying shrinkage is identical with the coefficient of expansion, has solved wood-based plate, because of the difference of the drying shrinkage and the coefficient of expansion, causes wood-based plate distortion, dry and cracked; Talcum powder in the composition, its drying shrinkage, the coefficient of expansion and little, stable, add filling property and oilness all is better than flour, it is first-selected being aggregate.Select for use above two kinds of materials to make additive, its sufficient material source, cost is low, under equal conditions can reduce the wood-based plate distortion and ftracture 40%, can increase wood-based plate intensity, improves the quality of wood-based plate.The wood-based plate of this glue additive for artificial board manufacturing has smoothly, does not ftracture, does not subside, does not go mouldy, makes full use of resource, environment-protecting asepsis, cost low (be flour price 60%), storage endurance, easy advantage such as transportation.
Embodiment
Embodiment one
Glue additive for artificial board was selected the solid wood wood powder of 260/300 mesh sieve for use, accounted for 85% of weight, added 15% 325/400 order talcum powder again, stir.
This example is applicable to the hardwood wood-based plate, and is on-the-spot with special machinery stirring 5 to 10 minutes, can be according to tackiness agent (using glue) performance, and its addition (weight) is adjusted between 15-20%.
Embodiment two
Glue additive for artificial board,, selected the solid wood wood powder of 260/300 mesh sieve for use, account for 80% of weight, add 20% 325/400 order talcum powder again, stir.
This example is applicable to the soft weedtree wood-based plate, and is on-the-spot with special machinery stirring 5 to 10 minutes, can be according to tackiness agent (using glue) performance, and its addition (weight) is adjusted between 20~30%.
Embodiment three
Glue additive for artificial board was selected the solid wood wood powder of 260/300 mesh sieve for use, accounted for 95% of weight, added 5% 325/400 order talcum powder again, stir.
This example is applicable to the wood-based plate winter construction, its addition (weight) 20%.
