Abstract

A reinforced wooden floor block with groove and tongue joint is made up of pine wood or the wood of quickly growing tree through making finger joining board, splicing them to obtain core board, sticking decorative veneer layer on its surface, adhering antiwear A2O3 layer on the decorative layer, high-temp. (130-165 deg.C) treatment, sticking moisture-proof flame-retarding melamine layer to its bottom, and making groove and tongue joint.

Description

Technology for manufacturing reinforced wood floor with compound groove and tongue

The present invention relates to a kind of production method of floorboard, particularly a kind of production method of solid wood composite tongue-and-groove floor block.

Existing solid wood floor block, generally be to adopt precious wood, a large amount of rare broad-leaved woods have not only been consumed, make floorboard cost height, uneconomical, the user is difficult for accepting, main is the easy harmomegathus of solid wood floor block, buckling deformation, install sealing big, perishable, easily damage by worms, wear no resistance, bending strength is poor;

Existing reinforced composite floorboard piece because core adopts high density fiberboard or particieboard, contains the aldehyde material harmful to health, and the consumer is trusted inadequately to fibrous plate.

The objective of the invention is the problem at existing solid wood floor block and the existence of consolidated floor piece, it is good to research and develop a kind of practicality, and cost is low, does not consume the production method of the reinforced wood composite tongue-and-groove floor block of national rare timber resources.

The present invention utilizes soft timber or fast-growing woods material, makes through following production stage:

One, selection:

Select mesomorphic soft timber or artificial fast-growing woods material or multiple-plate solid wood in the hardwood for use, by required specification selection or blanking;

Two, drying:

The dimension stock of choosing is put into lumber kiln carry out vapour degreasing, eliminate internal stress and physiology moisture content, make moisture content reach 6-8%, making the moisture regain phase moisture content behind the kiln discharge is 11-12%;

Three, processing:

1, with the woollen dimension stock behind the dry kiln discharge through planer, thicknesser, refer to cut, the processing of gluing, finger process sequence, and be spliced into section bar;

2, the section bar that is spliced into after the above-mentioned processing carries out jigsaw, sanding technology is made sheet material to passing through with four side moulder;

3, be central layer with above-mentioned sheet forming, at the central layer upper surface graining layer that sticks with glue;

4, one deck alundum (Al wearing layer that on the graining layer of sheet forming, sticks with glue again;

5, to finished above-mentioned technology, had wearing layer, the sheet material of graining layer, central layer, moisture retardant balance layer carries out conventional high-temperature processing technology, temperature is controlled at 135 °-165 °, makes between each layer and combines closely, and forms one;

6, paste moistureproof, fire-retardant balance layer in the central layer bottom surface, this balance layer can adopt melamine;

7, around every floor panels, dig the convex-concave tongue and groove, require size accurate, closely cooperate each other, promptly get the reinforced wood compound floor block to guarantee the floorboard tongue and groove.

The reinforced wood composite tongue-and-groove floor block of employing aforementioned production method production has overcome the defective of existing solid wood floor block and consolidated floor piece, the advantage that integrates solid wood floor block and consolidated floor piece, the natural wood sense that had both had solid wood floor block, have again the consolidated floor piece wear-resisting, corrosion resistant, moisture-proof, fire-retardant, antistatic, beautiful texture, color good luster, bending strength is good, harmomegathus is little, long service life, installation are simple, inexpensive, the advantage of maintenance easy to clean, makes ordinary consumer spend less money can obtain enjoyment senior, luxurious solid wood floor block.

Adopt the reinforced wood composite tongue-and-groove floor block, can save the rare broad-leaved wood of wildwood in a large number, make the purposes and the value of soft timber and artificial fast-growing woods material obtain exploitation and bigger lifting again, and cost reduces 30-50% than the floorboard of rare natural broad-leaved wood, cost than consolidated floor piece reduces 20-30%, can reach the grade and the class of senior solid wood floor block fully.

Enumerate embodiment below:

One, selection:

Adopting numb willow is core material, thickness 2.2cm, and width 3.2cm, length is 60cm.

Two, the rectangular material of the specification of choosing is sent into dry kiln and dry, make moisture content reach 12%.

Three, procedure of processing:

1, with the woollen material order of the numb willow behind the kiln discharge according to planer, thicknesser, refer to cut, gluing, finger technology be spliced into section bar;

2, with four side moulder the section bar that is spliced into through above-mentioned processing technology is carried out jigsaw, sanding, make sheet material;

3, with above-mentioned sheet forming as central layer, paste the graining layer at the central layer upper surface;

4, on the graining layer, paste one deck alundum (Al wearing layer;

5, to having finished above-mentioned each operation, the sheet material with wearing layer, graining layer, central layer, moisture retardant balance layer carries out conventional high-temperature process, and temperature makes between each layer and combines closely between 135 °-165 °, forms one;

6, paste melamine moisture retardant balance layer in the central layer bottom surface;

7, around every floor panels, dig the convex-concave tongue and groove, require processing dimension accurate, closely cooperate each other to guarantee floorboard.

After above-mentioned steps is handled, promptly get required reinforced wood composite tongue-and-groove floor block.

Claims
