Embodiment 1

[0013] Put the poplar veneer with a moisture content of 11% in a pressure tank for deep steaming and carbonization treatment, the pressure is 0.3MPa, and the time is 30 minutes. The veneer after the deep steaming treatment is balanced to an air-dry state, and the After fine repairing, heat-press the floor base material for use; use 2-4mm thick hardwood veneers that have also undergone deep steaming and carbonization treatment as the surface layer, and paste the above-mentioned floor base material with cold-pressed glue after secondary drying , to make a solid wood composite floor blank; the floor blank obtained after gluing can be grooved and painted to obtain a solid wood composite floor suitable for geothermal heating. After testing, its anti-swelling ratio (ASE) is 14.04%, the bending strength is 38.413MPa, and the modulus of elasticity is 3730.463MPa.

Embodiment 2

[0015] Put the poplar veneer with a moisture content of 14% in a pressure tank for deep steam carbonization treatment, the pressure is 0.5MPa, and the time is 15 minutes, and the veneer after deep steam treatment is balanced to an air-dry state, and After fine repairing, heat-press the floor base material for use; use 2-4mm thick hardwood veneers that have also undergone deep steaming and carbonization treatment as the surface layer, and paste the above-mentioned floor base material with cold-pressed glue after secondary drying , to make a solid wood composite floor blank; the floor blank obtained after gluing can be grooved and painted to obtain a solid wood composite floor suitable for geothermal heating. Its anti-expansion and contraction rate (ASE) was detected to be 72.33%, the bending strength was 38.55MPa, and the modulus of elasticity was 7131.94MPa.

Embodiment 3

[0017] Put the poplar veneer with a moisture content of 17% in a pressure tank for deep steam carbonization treatment, the pressure is 0.3MPa, and the time is 45 minutes. The veneer after the deep steam treatment is balanced to an air-dry state, and the After fine repairing, heat-press it into the floor base material and set it aside; use 2-4mm thick hardwood veneers that have also undergone deep steaming and carbonization treatment as the surface layer, and press the floor base material with cold-pressed glue after secondary drying. A solid wood composite floor blank is made; the floor blank obtained after gluing is grooved and painted to obtain a solid wood composite floor suitable for geothermal heating. After testing, its anti-swelling ratio (ASE) is 42.48%, the bending strength is 43.537MPa, and the modulus of elasticity is 5193.82MPa.

Abstract

The invention discloses a method for manufacturing engineered geothermic floors. The invention comprises the following procedures that: a cotton wood veneer or an imported miscellaneous tree veneer undergoes the process of deep steaming charring treatment under the pressure of 0.3 to 0.5MPa within 3 hours to obtain floor base materials; a hardwood plate with a thickness of 2 to 4mm is used as a surface course and the hardwood plate also undergoes the process of deep steaming charring treatment; the hardwood plate and the floor base material are made into a blank; after being glued, the obtained blank is made into the engineered floor suitable for geothermy after being notched and lacquered. The engineered floor suitable for geothermy has good corrosion resistance, weather resistance, stability and wearing resistance. In addition, the engineered geothermic floor accords with the modern idea of environmental protection and is easy to be maintained.

Description

technical field [0001] The invention relates to a method for steaming and carbonizing solid wood composite floors, which is especially suitable for ground heating. Background technique [0002] The geothermal floor heats the floor to a surface temperature of 18-30°C through the heating pipes buried under the floor. Therefore, the floor must be able to withstand a certain temperature for a long time. Deformation and paint deterioration will occur. At present, wood flooring can be roughly classified into: solid wood flooring, solid wood composite flooring and laminate flooring from the structure and materials. Among them, the solid wood composite floor has been pressed at high temperature, and the internal water content is very small, so it will not be deformed due to the loss of water; the internal layers are criss-crossed, interlaced, and restrained, and there are dense anti-deformation grooves on the back, which decomposes The resistance generated by the heating surface, ...
