Description
Technical field
The present invention relates to field, floor, particularly a kind of Double-layer composite wood floor and preparation method thereof.
Background technology
Along with mankind's environmental consciousness improves and the rise of fuel price, the precious timber that China can be used for wooden floor production is fewer and feweri, causes wooden floor to hold at high price.And wooden floor is easily out of shape, shrinks, installation cost is high, easily make moist, not fire-resistant, easily damage by worms.For alleviating the situation of this anxiety, the consolidated floor that domestic production is a large amount of and composite floor board meet consumer demand.
Consolidated floor generally adopts and overlay woodgrained paper on medium density fiberboard base material, is doing the process of wear-resisting and surperficial paint, in addition, compared with wooden floor, deformation retract amount is little, not moisture-sensitive, not easily moth.And consolidated floor uses bonding adhesive in process of production, the release of its formaldehyde is inevitable, and consolidated floor is not prevented fires, and safety factor is low.
Composite floor board is floor decorative material popular in recent years; its mode of production has two kinds; one is after log is pulverized; dose glue, anticorrisive agent, additive; form through hot press HTHP compression process again; the composite floor board of this mode of production manufacture has broken the physical arrangement of log, overcomes the weakness of log poor stability; But due to the bonding adhesive used in manufacturing process, the content of formaldehyde of generation controls bad, easily transfinites, the house after finishing to continue to produce pungent smell.
Solid wooden compound floor is formed by the sheet material crosswise lamination of different tree species, and overcome the shortcoming of the unidirectional same sex of wooden floor, expand with wet and contract with dry rate is little, has good dimensional stability, and remains the natural wood veins of wooden floor and comfortable feel.Solid wood compoiste wood floor is divided into three-layer wood composite flooring, multi-layer solid wood composite floor, Novel solid wood composite floor three kinds, solve the yielding not wear-resisting defect of wooden floor, and feel is comfortable especially.But the solid wooden compound floor in currently available technology is due to the restriction of its manufacture craft, generally veneer or clamping plate are adopted to be base material, unavoidably there is Form aldehyde release, when being used under northern geothermal environment on these floors of prior art, the release of its formaldehyde is more serious.
Along with the raising of customer's environmental consciousness, customer more wish a kind of environmental protection, nonpoisonous and tasteless "dead", inexpensive, fire-proof and water-proof wood floors to beautify family.And these floors of the prior art still can not meet the needs of people.
