Description
Technical field
The invention belongs to timber floor technical fields, are related to composite floor board of cork wood, more particularly to compound as substrate cork using OSB
Floor.
Background technique
Cork is called cork, is cork actually and non-timber because its is soft and high resilience is commonly called as cork admittedly
The bark of tree species quercus suber, cork oak.Cork be it is a kind of it is pure natural, can be with regenerated natural resources.Because close among its material
Envelope space porosity accounts for 70%, this makes cork have the characteristics that density is low, quality is soft, squeezable.
Cork flooring is to form plate by crushing, hot pressing, then add by mechanical equipment using high-quality natural cork as raw material
Work forms floor.Cork flooring has health, superperformance soft, comfortable, feel is good, antifatigue, microtexture feature
Determining cork flooring has that light, elasticity is good, heat-insulated, sound insulation, water proof, the good characteristics such as moisture-proof, fire-retardant, soft, wear-resisting.
Cork flooring is mute floor board generally acknowledged in the industry, such as quiet meeting room, advanced movie theatre and music hall, is applied at this
A little places can effectively avoid noise pollution.The resilience of cork can be substantially reduced due to being stood for a long time to human body back, leg, foot
Pressure caused by ankle, while being conducive to the kneed protection of the elderly, accidental falls can be worked as a buffer, it can be to greatest extent
The extent of injury of ground reduction human body.Meanwhile cork flooring has relatively good skid resistance, anti-skidding characteristic is compared with other floors
It is also its maximum feature, old man walks above and is not easy to slide into, and increases the safety used.It is child room, Lao Renfang, dancing
The optimal selection in room.
OSB be oriented wood chipboard (abbreviation of Oriented Strand Board, be it is a kind of with log, it is undersized log, secondary small
Yule logs, wooden core, slab, brush wood etc. are that raw material through drying, is applied along grain direction slicing at the wood shavings of certain geometrical shape
Glue, by a kind of wood-based plate made of the criss-cross orienting spreading of wood shavings, molding hot pressing, saw side sanding etc. master operations compacting.
Since oriented wood chipboard uses special process and many special equipments, the natural characteristic of timber is remained substantially,
Therefore it is high with bending strength, linear expansion coefficient is small, good stability of the dimension, nail-holding ability are strong, consumption glue amount is low, is easy to carry out surface
The advantages that decoration, is easy to the machining such as sawing, drilling, planing, and substrate uses PMDI glue, and such glue is without formaldehyde and insoluble
Yu Shui, it is ensured that the environmental protection quality of product and brilliant waterproof performance.
Summary of the invention
It is an object of that present invention to provide a kind of no added aldehyde environmental protection, comfortable foot feeling, it is mute it is moisture-proof, be easy to arrange, structure is steady
It is fixed, excellent in mechanical performance, the functional form floor convenient for mating formation.
In order to achieve the above-mentioned object of the invention, it adopts the following technical scheme that
OSB composite floor board of cork wood, from top to bottom successively by aqueous painting finish coat, cork decorative layer, upper ply, OSB base
Material layer, lower ply and the mute bottom composition of cork；Wherein the upper ply and lower ply are symmetrically distributed in OSB substrate
The two sides and its grain direction of layer are parallel with the substrate layer surface wood shavings direction OSB.
Preferably, the cork decorative layer is one layer of 0.5~1.5mm virgin softwood decorative layer, density is in 0.65g/cm3
Left and right, surface texture are imitative natural cork texture, imitative precious timber, parian texture or imitative carpet texture.
Preferably, the mute bottom of cork is one layer of 2~3mm cork mute layer, density is in 0.45g/cm3Left and right.
Preferably, OSB substrate layer is with a thickness of 7~9mm, density 0.75g/cm3More than.
Preferably, aqueous painting finish coat is sealing wax coatings, coating is followed successively by aqueous tint lating, water from bottom to top
Property UV transparent underlayer, the aqueous wear-resisting bottom of UV, aqueous UV transparent surface layer.
Compared with prior art, the invention has the following advantages:
Composite floor board of cork wood feel soft comfortable provided by the invention, non-skid property is good, can absorb the function of noise,
OSB substrate layer undertakes effect interconnected between floor by mortise, slot, and floor is made to be connected to become entirety, guarantees floor peace
Fill efficiency and installation quality, upper and lower ply is balance layer, play balance, increase mechanical strength, pasted for cork layer provide it is excellent
The effect of matter cemented surface.
