Abstract

The invention discloses a production method of a double-layer solid wood flooring. The method comprises the following steps of: radially cutting China fir into a veneer serving as a blank plate of a bottom plate; radially cutting acokanthera venenata wood or german oak wood or irko wood or castanopsis chinensis hance wood into a veneer serving as a blank plate of a faceplate; cooking and degreasing the sawed faceplate blank plate; baking and making the strength of the faceplate equal to or less than that of the bottom plate by changing the thickness of the blank plate according to the different bending strengths of the two kinds of blank plates, coating a hot pressing glue on the China fir blank plate and the faceplate blank plate with the same deflexion, and compressing and moulding the blank plates in a press, and controlling the temperature to be between 90 and 100 DEG C, wherein the pressure is 16 to 20kg per square centimeter; and planning and sanding the hot-pressed moulded plate. In the method, two kinds of different woods are adopted to mould the double-layer solid wood flooring at a high temperature under a high pressure, so that the advantages of the two kinds of woods complement each other. The double-layer solid wood flooring is fully dried through ultraviolet light irradiation. Horizontal bends and warps are removed by planning without pressure and are subjected to difference match and stress balance treatment, so that the problem which is difficult to solve by bowing deformation is effectively solved.

Description

The production method of dual-layer wood floor

Technical field

The present invention relates to a kind of timber floor production method, particularly a kind of dual-layer wood floor production method.

Background technology

Because wood floors have the untouchable many excellent specific properties of other floor decorative materials, and are comfortable like feel, fine setting environment humidity, harmless to health, thereby enjoy people to favor; At present, timber floor is broadly divided into former timber floor and multiple field timber floor two big classes.

Though former timber floor has kept self characteristics and pure natural property fully, a kind of material can not satisfy the many specification requirements to the floor; The easement distortion can't overcome, and the monolithic plank is thicker, and parching property of influence is had relatively high expectations to environment for use, and changing slightly is easy to generate distortion, influences attractive in appearance and service life.

Though the multiple field timber floor has crisscross level, unordered distortion is wayward, still can not overcome easement distortion, no matter be quarter sawing or rotary-cut, always the internal layer space has; These spaces have increased glue consumption, and harmful substance is also corresponding to be increased.

Summary of the invention

The objective of the invention is to overcome the shortcoming of prior art, provide a kind of usefulness two kinds of different timber, be bonded through HTHP, it is wear-resisting to have a panel, and negative is soft, on-deformable dual-layer wood floor of stable performance and production method thereof.

The production method of dual-layer wood floor of the present invention comprises the steps:

1, get China fir and radially be cut into veneer and make the base plate blanket and use, getting China fir, to make negative be because China fir can be finely tuned self humidity with environmental change, makes it to produce moisture-proof function; Immortal in the certain environment following centuries of condition; China fir is the length fibre structure, and bending strength is good, belongs to the less excellent material of a kind of deflection; Be commonly called as the king in the wood, China fir also has the characteristic strong with the glue adhesion; Experiment showed, China fir and chinquapin wood behind hot pressing, gummed, boiling can not be ftractureed in one hour in pressure cooker;

2, get chinquapin wood and radially be cut into veneer, it is for use to make the panel blanket, and getting chinquapin wood, to make panel be because chinquapin wood has the natural anticorrosion function, the unavoidable and boiling water as the total surface on floor, and the contact of liquid such as children's urine is so the moisture-proof anticorrosive on floor is absolutely necessary; Chinquapin wood also has density high, wear-resisting, withstand voltage, fire-retardant characteristics; Making panel with chinquapin wood is one of best material, and the certainly also iron jujube of available this locality, blue or green firm etc., or the disk beans of import etc. is cooked the panel material, but on comprehensive function, can't compare favourably with chinquapin wood;

3, will saw good panel wood blanket and carry out the boiling degreasing;

4, the panel blanket after China fir blanket and the degreasing is contained in respectively in two different drying rooms dries; Material is put and is adopted goods-shelf type built on stilts, divides three phases to heat up, and environment temperature～30 ℃ are the I stage; 30 ℃～60 ℃ is the II stage, and ultraviolet illumination is the III stage, and ultraviolet facility is 5 each ultraviolet light generators of 1 kilowatt; Be distributed in the drying room, adopting this technology is in order to let blanket fully parch, because of the water evaporates of ultraviolet illumination ability quick active deep layer; Chinquapin wood baking needed time and temperature Duo 15～20% than China fir, and the three phases time spent equates, panel blanket oven dry total time is 5～9 days; Material goes out drying room needs emphasis parching property of check and uniformity, and only the parching property of guaranteed material and uniformity could guarantee the indeformable or small deformation of product;

5, the above-mentioned blanket that will dry does not have the pressure planing, removes lateral bending (horizontal curved) and song and sticks up, and looks its degree if any the blanket of natural flaw and carries out traceless repair, and the just remaining easement of the blanket of having planed is not so handled;

6, difference coupling reaches through the thickness that changes blanket according to the different bending strength of above-mentioned two kinds of blankets that intensity equates or panel is weaker than base plate, and the thickness of base plate and panel is than being 2.5-4: 1;

7, press shown in the accompanying drawing, represent the easement deflection of two kinds of blankets with amount of deflection 1,2,3,4,5, because every compact plate all can have certain flexibility, we are defined as the A face to bandy face, and aduncate face is defined as the B face.And defining one meter long blanket, crooked arc apex is amount of deflection 1 to the distance of string for the 0-1 millimeter; Distance is an amount of deflection 2 for the 1-2 millimeter; Distance is an amount of deflection 3 for the 2-3 millimeter; Distance is an amount of deflection 4 for the 3-4 millimeter; Distance is an amount of deflection 5 for the 4-5 millimeter;

8, the B of China fir blanket that two amounts of deflection is identical and panel blanket coats hot pressing glue and in press, presses solidly moulding in the face of the B face, and temperature is controlled at 90 ℃～100 ℃; 16～20 kilograms every square centimeter of pressure, pressure is excessive or too small all unsuitable, and this method is called stress equilibrium;

9, the profiled sheeting that hot pressing is good also has a spot of easement distortion, after adjustable cast iron planes and sanding, all can eliminate.

The present invention adopts the dual-layer wood floor of two kinds of different timber through the HTHP moulding, and the mutual supplement with each other's advantages of two kinds of materials of collection fully parches through ultraviolet lighting again; No pressure planing is removed horizontal bending with song and is stuck up, and through the difference coupling, stress equilibrium is handled again, efficiently solves the problem that the easement distortion is difficult to capture.
