Description

A kind of solid wooden compound floor and manufacture method thereof that is suitable for underground heat

Technical field

What the present invention relates to is a kind of ad hoc structure and manufacture method of solid wooden compound floor, is particularly useful for ground heating and uses.The manufacturing technology field that belongs to solid wooden compound floor.

Background technology

At present, known wood flooring can be divided into substantially: wooden floor, solid wooden compound floor and consolidated floor three major types.So-called wood composite floor heating floorboard is exactly to be applicable to that what lay when heating system is the ground heat supply is the floor that raw material is made with the solid wood in fact.Because the distance between heating floor and the thermal source is very little, heat source temperature may reach 70 ℃, and the heat supply phase is very long, and will transmit heat by the floor, and there is the temperature difference in the floor upper and lower surface, and these unfavorable factors are all seriously testing the quality of heating floor.Therefore in the manufacturing and use of heating floor, not only to guarantee lower moisture content, but also should have the ability that ambient humidity variation causing moisture content changes of resisting.Timber is as a kind of natural ecological environment material nd, and under conditions such as certain humiture, most timber are rotten easily and damaged by worms, and timber-work also can produce drying shrinkage, bulking phenomenon along with the difference of environment for use.This also just wood floors in use change the main cause that produces defective owing to material, structure, production technology and environment for use.

Summary of the invention

The objective of the invention is to propose a kind of solid wooden compound floor and manufacture method thereof that is suitable for underground heat, it can effectively overcome existing wood flooring and in use be prone to warpage and distortion, and the structure of existing underground heat wood flooring is unfavorable for the defective of heat transmission (mainly by heat conduction).

Technical solution of the present invention: comprise dash board and base plate, it is characterized in that dash board is arranged on the carbonized wood base material base plate, stick with glue the agent gummed and form; On carbonized wood base material base plate, offer air vent perpendicular to ground surface; Described carbonized wood base material base plate is formed through subdivision by the blank of base material base plate; The blank of described base material base plate is the individual layer jigsaw interval assembly by individual layer jigsaw and cutting, and forms along the crisscross odd-level multilayer gluing that is of machine direction, and the individual layer jigsaw of cutting is not two external surfaces of base plate; The individual layer jigsaw of described cutting is to be formed along the machine direction cutting by the individual layer jigsaw, and described individual layer jigsaw is assembled by some thin plates, and described thin plate is formed by carbonized wood blank subdivision.Described individual layer jigsaw is assembled by some thin plates, and described thin plate is formed by carbonized wood blank subdivision.

A kind of manufacture method that is suitable for the solid wooden compound floor of underground heat is characterized in that being divided into one, the preparation of solid wooden compound floor dash board; Two, the preparation of composite floor board base material; Three, the preparation of composite floor board.

Wherein one, the preparation of solid wooden compound floor dash board: the dash board blank of certain size specification is carried out drying, make its moisture content 6-12%, be split into the thick dash board finished product of 3~6mm with buck saw or splitting machine.

Two, the preparation of composite floor board base material: adopting the composite construction of fast growing wood solid wood splicing, specifically is fast growing wood carbonized wood blank to be carried out charing handle 160~240 ℃ of its treatment temperatures; Fast growing wood carbonized wood blank after charing is handled is carried out machining, and the thin plate side gluing after the machining forms the individual layer jigsaw, between the adjacent individual layer jigsaw one group of individual layer jigsaw that needs along the machine direction cutting is arranged when assembly; With the individual layer jigsaw of individual layer jigsaw and cutting along the crisscross odd-level assembly at interval that is of machine direction, adopt common press gummed, pressure 1.0-1.5MPa, hot pressing 0.8-1.0min/mm pressing time blanket is thick, the individual layer jigsaw of cutting is not two external surfaces of base plate, and then obtains base material (base plate) blank of multilayer gluing; Base material (base plate) blank of multilayer gluing is carried out subdivision by the thickness requirement of base material, obtain the base material finished product; Thickness 8~the 20mm of base material finished product; Form air vent on the base material finished product perpendicular to ground surface.

Three, the preparation of composite floor board: the dash board finished product and the floor base material finished product that prepare are glued together, adopt common press, pressure is 1.0-1.5MPa, hot pressing 0.8-1.0min/mm pressing time blanket is thick, the heating floor blank that obtains behind the gummed, carry out machining again, and handle the solid wooden compound floor finished product that obtains being suitable for underground heat through leaching paint.

Advantage of the present invention: the fast growing wood carbonized wood is used for the preparation of compoiste wood floor base material as a kind of new material, not only widen the application of artificial fast growing wood, save a large amount of hardwood resources, and made composite floor board have good biodurable, weatherability and dimensional stability; Because the machine direction of base material finished product interlacing respectively is parallel or perpendicular to ground (or plate face), being criss-cross arranged like this reduced the distortion of base material (base plate) further, base material (base plate) is gone up unique air vent design and manufacturing process simultaneously, realize heat convection local between ground and the dash board, guaranteed the quick transmission of ground heat.Compare with existing wood floor technique, this solid wooden compound floor has not only been saved precious dash board resource, and has good biodurable, weatherability and dimensional stability.In addition,, make between ground and dash board, to have formed local heat convection, further reduced the temperature difference that the floor upper and lower surface exists owing to special vent hole structure in the composite floor board base material (base plate).
