Outdoor bamboo floor
The present invention relates to an outdoor bamboo floor and a manufacturing method thereof, in particular, to an outdoor bamboo floor subjected to an immersion treatment using hot oil. Conduits or other capillary structures of a bamboo material in the outdoor bamboo floor of the present invention are filled with an oil medium, with an oil content of 2-10%. The manufacturing method includes immersing a plate blank of the bamboo floor in a hydrophobic organic medium at 100-300° C. for 1-10h, and are statically cooled down to a room temperature after being taken out.
1. An outdoor bamboo floor, wherein conduits or other capillary structures of a bamboo material in the bamboo floor are filled with an oil medium, with an oil content of 2-10%,
wherein the oil medium filled in the conduits or other capillary structures of the bamboo floor is one or more of an alkylbenzene typed conduction oil, mineral substance oil, alkyl biphenyl typed conduction oil, alkyl biphenyl ether typed conduction oil, biphenyl, and biphenyl ether eutectic mixture typed conduction oil or alkyl naphthalene typed conduction oil,
wherein the bamboo floor has a thickness swelling rate of water absorption greater than 2.5% and less than 3.1%, or greater than 7.5% and less than or equal to 10%,
wherein the bamboo floor is a recombined bamboo floor, the recombined bamboo floor is formed by laminating bamboo filaments or bamboo chips with an adhesive,
wherein the conduits or other capillary structures are filled by an oil immersion treatment step, wherein in the oil immersion treatment step, after the bamboo material is cold pressed and molded, the material is vertically immersed.
2. The outdoor bamboo floor according to claim 1 , wherein the oil medium is evenly distributed on each section of the bamboo floor.
3. The outdoor bamboo floor according to claim 1 , wherein a moisture content of the bamboo floor is 1-5%, a mildew and discoloration preventing performance harmed value is 0, a width swelling rate of water absorption is 1-4.5%, and a horizontal shear strength is greater than or equal to 12 MPa.
4. The outdoor bamboo floor according to claim 3 , wherein the thickness of the bamboo floor is 30-40 mm.
5. The outdoor bamboo floor according to claim 4 , wherein the thickness of the bamboo floor is 40 mm.
6. The outdoor bamboo floor of claim 1 , wherein the bamboo floor has a thickness swelling rate of water absorption of 9%.
7. The outdoor bamboo floor of claim 1 , wherein the bamboo floor has a thickness swelling rate of water absorption of 2.7%.
