Abstract
The invention discloses a medium density fiberboard prepared by using a geopolymer as a cementing material. A conventional medium density fiberboard is prepared by using wood fibers as raw material and urea-formaldehyde resin or other chemical adhesives as the cementing material, and the conventional medium density fiberboard finished product contains toxic substances and is harmful to health. The medium density fiberboard disclosed by the invention is prepared by adopting a geopolymer synthetic technology, using geopolymer mineral powder as the cementing material and sawdust as a main raw material and adding water glass and calcium carbonate powder. The adopted raw materials are green and environmentally-friendly materials, non-toxic and harmless. The medium density fiberboard has the advantages that lots of geopolymer and sawdust are added in the production process, so that the resource of wood material is saved, the medium density fiberboard is low in cost, the raw materials are green and environmentally-friendly, plenty of solid wastes such as mineral powder can be used, the high temperature and the high pressure are not needed in the production process, the production is carried out at a normal temperature, the energy consumption is low, the site area occupied by production is small, and the shortcomings of toxicity, high energy consumption and the like in conventional medium density fiberboard production are effectively overcome.
Description
Technical field
The present invention relates to a kind of density board that ground polymers is gelling material of take, belong to building material technical field.
Background technology
Timber is a kind of indispensable resource, along with social development, improving constantly of living standards of the people, wood materials can not meet the needs of the people's lives of development, cause forest to have by the trend of overcut, timber resources critical shortage, timber price constantly rises and supply falls short of demand, the substitute of wood materials is also just arisen at the historic moment, and density board is exactly one of substitute of wood materials.
Density board is a kind of artificial board of nineteen nineties origin.This product is since coming out, sell well in the international market always, be active in the industrial circles such as building materials, furniture, household electrical appliance, musical instrument, vehicle and shipbuilding, use range expands year by year, whole world high-density plate year output is 8,560 ten thousand square metres at present, 13,750 ten thousand square metres of demands, and with annual more than 16% speed increment, good market prospects.At present, the density board occurring on market is all that to take wood fibre or other plant fiber be raw material, applies the artificial board that urea-formaldehyde resin or other applicable tackiness agent are made.Although these density board physicalies are fabulous, material is even, does not have the problems such as dehydration, but also there are a lot of shortcomings, be summarized as follows: 1, in production process, added trimeric cyanamide, although also added activated carbon, but can not absorb the toxic substance that density board gives out completely, be harmful to health.2, in production process, need high temperature hot pressing, energy consumption is high, waste national energy.Obviously, traditional density board has still been used a large amount of wood fibres, causes equally the shortage of wood materials.Seek a kind of material of alternative density board, the service performance of existing density board and efficacy effect, can reduce again the usage quantity of wood materials, and this,, for saving wood materials resource, is a large technical progress, is the target of pursuing in this technical field.And Here it is meaning of the present invention.
Summary of the invention
The object of this invention is to provide and take the density board that ground polymers prepared as main raw material as gelling material, the sawmilling chaff of take, overcome the shortcomings such as current density board is poisonous, production process energy consumption is high, lignocellulose raw material usage quantity is large.
The realization of foregoing invention object is to have adopted following technical measures: a kind ofly take the density board that ground polymers is gelling material, mainly the raw material by following weight parts is prepared from:
Sawmilling chaff 50-65 part, breeze 10-25 part, water glass 4-10 part, Paris white 15-30 part;
The sawmilling waste producing in described sawmilling Kang Wei wood-working factory production process;
Described breeze is fineness 300-600 object blast furnace granulated slag;
Described water glass is process modification, and modulus is 1.5-2.5, and solid content is 30% service water glass;
Described Paris white is that commercially available relative density is 2.83, and fusing point is the 200-300 order Paris white of 825 ℃;
Above-mentioned starting material are prepared by following method:
(1) proportionally take various raw materials;
(2) the sawmilling chaff taking and the breeze and the Paris white that take are joined to mixing and blending machine, under the speed of 120r/min, disperse 2min, obtain mixing dry raw material;
(3) water glass taking is joined in the dry raw material mixing and stirs and obtain base material;
(4) at normal temperatures, by base material extrusion molding in special-purpose mould, maintain after 3-7 days, then polishing is slotted and is obtained density board finished product.
Take the present invention of above-mentioned measure, employing be to take ground polymers as gelling material, take sawmilling chaff as main raw material, starting material are all green material, nontoxic.Add in a large number in process of production ground polymers and sawmilling chaffs, saved wood materials resource, not only low, the starting material environmental protection of cost, can utilize in a large number the solid waste such as breeze, production process without high temperature hot pressing, normal temperature carries out, energy consumption is low, produce the little advantage of occupied ground area, effectively overcome the shortcomings such as traditional density board is produced exist poisonous, energy consumption is high.And the waste of sawmilling Kang Shi wood-working factory production, the present invention be take sawmilling chaff as main raw material, can turn waste into wealth, and protection of the environment, reduces saw wood ash burning or piles up the pollution to environment.It is the uniqueness innovation of preparation density board.
