The utility model content:
The technical problem of hazardous substances releases such as the purpose of this utility model is to provide a kind of environment-friendly type composite floor board, solves composite floor board and has the walking comfort identical with single wood flooring, walks and does not have loud footsteps when it is gone up, and is simultaneously formaldehydeless again.
The technical scheme that the utility model solves the problems of the technologies described above is:
A kind of environment-friendly type composite floor board comprises the central layer of wood-based plate of panel, string compacting of high-quality wood single-plate and the base plate of common wood veneer, and it is characterized in that: the thickness of this panel is 1.5～2.5mm; With bonding agent hot pressing thickness being arranged between panel and central layer is the poplar of 0.8～1.2mm or the intermediary layer of pine veneer, and the machine direction of this intermediary layer timber is consistent with the lumber fibre direction of panel; This central layer is the formaldehydeless high-strength artificial plate of string length in 0.1～6mm size.
This technical scheme can also further be improved to: the thickness of this base plate is 1.5～2.5mm, also with bonding agent hot pressing thickness being arranged between central layer and base plate is the poplar of 0.8～1.2mm or the intermediary layer of pine veneer, and the machine direction of this intermediary layer timber is consistent with the lumber fibre direction of base plate.
The bonding agent of panel, central layer, base plate and intermediary layer is formaldehydeless different hydrogen acid ether (hydrogen acid ester) in the technique scheme.
The utlity model has following beneficial effect:
1. adopt commercially available formaldehydeless high-strength artificial plate to make central layer, and use formaldehydeless different hydrogen acid ether (hydrogen acid ester) to make cementing agent, the formaldehyde that product is not had be harmful to health discharges problem.
2. owing between surface layer and sandwich layer, increased the soft poplar of quality and the intermediary layer of pine veneer, make the people have the comfort of a kind of walking on the floor of making by wood single-plate.
3. the agronomic crop fibre length of central layer is more much shorter than general commercially available waterproof string density board, so its sound-absorbing effect is better than the latter.Therefore walking can not sent loud footsteps on environment-friendly type composite floor board of the present utility model, gives quiet environment of indoor manufacturing.
4. the lumber fibre direction of panel and intermediary layer is different with the mutual vertical interlaced of prior art, but the direction unanimity, this had both made things convenient for processing and manufacturing, had also saved consumption of wood.
5. panel and the intermediary layer thickness and the thickness of prior art panel simultaneously is suitable, therefore can further reduce the consumption of high price high-quality timber, and reduce cost.
6. intermediary layer uses the poplar that the floor industry does not adopt, and has enlarged the purposes scope of poplar.
