Abstract
A kind of wooden floor with excellent water-fast and absorbing property, by solid wooden floor board layer, inhale wave adhesive layer, water absorption sponge layer forms.Wooden floor of the present invention with excellent water-fast and absorbing property, it is structurally reasonable, wherein the additional electromagnetic wave that home electronics can be generated in use by inhaling wave adhesive layer absorbs, and can effectively prevent the injury to human body.Furthermore water absorption sponge layer can effectively adjust water content in solid wooden floor board layer by absorbing foam, and when the water content that makes moist is excessively high, its excessive moisture can be sucked out in water absorption sponge；When indoor environment is excessively dry, when timber water content is too low, water absorption sponge layer can discharge its internal moisture to solid wooden floor board layer；To control its moisture content in OK range, extend solid wooden floor board uses the time, improves its using effect.
Description
Technical field
The invention belongs to house fitting-up technical field, be related to it is a kind of with excellent water-fast and absorbing property novel solid wood
Plate and preparation method thereof.
Background technique
Solid wooden floor board is a kind of floor decorative material made of the subsequent handlings such as natural timber drying, processing.Because of it
Texture has been increasingly becoming the ideal material of current house fitting-up naturally, using safe, can be used for bedroom, parlor, study etc.
Ground surface finishing.But traditional solid wooden floor board has been easy steam and has been entered in solid wooden floor board by pore after being laid with to floor, thus
Lead to solid wooden floor board dampness deformation.For the wood structure in actual use, timber particularly significant for the control of its moisture content
Equilibrium moisture content can change with the variation of the temperature and humidity locating for them, when water content and ambient humidity have difference
When, can be intended to will cause the bulking and drying shrinkage phenomenon of timber close to environment, this will be used for impacting, for
For the timber on floor, be easier to deform caused by the variation because of its moisture content, influence using.
Existing patent CN 207660247U provides a kind of wooden floor, which is to prevent floor from making moist
Deformation blocks the hair of solid wooden floor board by paint film using the technique of the front and back spraying paint film to solid wooden floor board main body
Hole prevents steam from entering in solid wooden floor board by pore, thus to prevent solid wooden floor board dampness deformation.But spraying paint film will affect
The using effect of solid wooden floor board reduces itself texture；With using the time to extend, the water content of floorboards of wood itself can be obvious
It reduces, it is easy to damage that too low moisture content will also result in timber itself；A large amount of VOC can be brought to remain simultaneously, not environmentally and for a long time
Contact is harmful to the human body.
