Description

A kind of processing method of laminated flooring

Technical field

The invention belongs to the processing method of laminated flooring, relate to laminated flooring specifically with stereoscopic visual effect.

Background technology

Chinese patent literature ZL03112761.4 " laminated flooring and manufacture method thereof " discloses a kind of manufacture method with laminated flooring of three-dimensional appearance effect, and this method has obtained patent right.

The method one of this patent has following steps: 1. by from bottom to top order balance paper (12), fiberboard (11), woodgrained paper (13) and abrasion-proof paper (14) are set on the lower-die steel plate of hot press; The last steel form of hot press has been the steel plate that has spacing distance width alternate " V " shape convex tendon on the working face, the last steel form of hot press by having " V " shape convex tendon is to balance paper (12), fiberboard (11), woodgrained paper (13) and abrasion-proof paper (14) are exerted pressure, in temperature is 190-200 ℃, pressurize 25-45 second under the condition of pressure 20-25MP, and make balance paper (12), fiberboard (11), woodgrained paper (13) and abrasion-proof paper (14) are bonding successively, simultaneously in fiberboard (11), woodgrained paper (13) and abrasion-proof paper (14) are gone up disposable mold pressing and are gone out " V " connected in star (1-22), formation has the big plate of alternate " V " connected in star of spacing distance width, and the distance between " V " connected in star of big plate width centreline both sides is narrow apart from f; 2. the big bladed saw that will have " V " connected in star with the saw board device becomes the small pieces of required size, and cuts along the center line between its each narrow distance of " V " connected in star, and each small pieces both sides respectively has " V " connected in star; 3. carry out the health of sign indicating number heap timeliness, conditioned time is at least 8 days; 4. be processed to form the tenon and the groove of vertical and horizontal in small pieces four sides, and obtain finished product; This moment, " V " connected in star of small pieces both sides only kept half, and half " V " connected in star of the every side in the left and right sides is the inclined-plane at edge, the main body left and right sides, floor.

The method two of this patent has following steps: 1. by from bottom to top order balance paper (12), fiberboard (11), woodgrained paper (13-1) and abrasion-proof paper (14-1) are set on the lower-die steel plate of hot press; Hot press is exerted pressure to balance paper (12), fiberboard (11), woodgrained paper (13) and abrasion-proof paper (14) by the mold pressing steel plate of light face or embossment, in temperature is pressurize 25-45 second under 180-200 ℃, the condition of pressure 20-25MP, and make balance paper (12), fiberboard (11), woodgrained paper (13) and abrasion-proof paper (14) bonding successively, form the big plate in plane; 2. with the saw board device big bladed saw is become the small pieces of required size; 3. carry out the health of sign indicating number heap timeliness, conditioned time is at least 8 days; 4. be processed to form the tenon and the groove of vertical and horizontal in small pieces four sides, 5. be provided with tenon and groove small pieces working face both sides are processed to form the inclined-plane, paste woodgrained paper (13-2) on the inclined-plane, surface spraying resin varnish; After the resin varnish drying, promptly make finished product.

There is the too high problem of defect rate in the method one of above-mentioned prior art.The step of method one 1. in, with four layer materials of traditional laminated flooring, balance paper, fiberboard, woodgrained paper and abrasion-proof paper, hot pressing surfacing process and inclined-plane pressing process carry out synchronously; Be provided with the convex tendon on compacting inclined-plane with last steel form with the hot pressing surfacing process.At present, its pressure of press of most of laminated flooring enterprise is at the 900-1400 ton; With method one, step 1. in, " spending in vain " usually can appear in the upper edge of the groove that is extruded by convex tendon on the big plate, medium-density plate (every cubic metre of 730-800 kilogram) can be few, high-density plate (every cubic metre of 800-1100 kilogram) can occur in a large number.There is the plate of " spending in vain " just to become substandard products.The inclined-plane of groove with on the walking hand-deliver place of converging " spending in vain " of occurring, be that a kind of woodgrained paper and fiberboard do not stick, perhaps woodgrained paper and fiberboard have sticked but abrasion-proof paper and woodgrained paper do not stick, not have mold pressing be well a reason in the part when phenomenon that the space is arranged therebetween, this and plastic mould pressing.If the pressure of press is brought up to the 1800-2400 ton, situation can be with the increasing and improve of pressure, and " spending in vain " can no longer appear in medium-density plate, and high-density plate still can't be stopped fully; Can not use and the change of pressure means original equipment, drop into every hundreds thousand of RMB again and acquire equipment.

Its on two the manufacturing expense of steel form too big.In the production of laminated flooring, last steel form in the hot pressing surfacing process usually is not the light face, but tiny convex-concave shape surface, it will process the convex-concave shape surface of non-specular surface on laminated flooring, as relief surface, quartzy face, the sheen face, milled sand surface, trade mark face or the like, many styles are arranged again in each class, and total quantity is up to hundreds of.On last steel form, have convex tendon with said method one,, will on the face type of each market demand, all will have convex tendon to reach hot pressing veneer and the one step completed purpose of compacting groove.Because the last steel form of hot pressing veneer will have very high Pingdu, the adding of convex tendon can not destroy this Pingdu, thereby also very high to the requirement on machining accuracy of convex tendon, makes the processing charges of going up steel form rise at double.High processing request like this is brought in each the last steel form that will use, and the manufacturing expense of the last steel form of enterprise is too big.

There is the low shortcoming of production efficiency in the method two of prior art.The step of method two 1. in, the hot pressing veneer of big plate does not form the inclined-plane, but in big bladed saw is become plate, therefrom bladed saw become platelet and hold tenon successfully and groove after reprocess the inclined-plane, its processing mode still cuts and sticks woodgrained paper again behind the inclined-plane and varnish.Its efficient of single inclined-plane machine-shaping of this each small pieces is not as the once working (machining) efficiency height of compacting of method one, and its cost can be not low yet; And the woodgrained paper of woodgrained paper on the inclined-plane and last walking surface also is not one, and user in use inclined-plane woodgrained paper comes off and the phenomenon that warps can occur, and the quality of product is good not as the woodgrained paper one.

The content of invention

The objective of the invention is to overcome the deficiency of above-mentioned prior art, a kind of processing method of laminated flooring is provided, the pressure that it has the processing press requires low, the yield rate height, the advantage that working (machining) efficiency is also high, thereby can under lower cost, produce high-quality timber floor with stereoscopic visual effect.

Technical scheme of the present invention is: a kind of processing method of laminated flooring, the thin layer surface lining is attached to the wooden substrate surface of bulk with hot pressing veneer method, with the saw board device bulk thick china is sawn into a plurality of small piece plates, it is characterized in that hot pressing veneer on the bulk wooden substrate, finally can form groove with compacting, implement compacting at twice with two last steel form A, B and form with stereoscopic visual effect; At first with minute surface or last steel form A hot pressing veneer on the bulk wooden substrate of tiny convex-concave is arranged, then with the last steel form B that convex tendon is arranged on the bulk thick china, suppress and finally can form groove with stereoscopic visual effect.

The processing method of aforesaid laminated flooring is characterized in that going up the steel form timesharing for two uses same press or be divided on two press.

The basic thought of processing method of the present invention is: with the press of conventional pressure, no matter remove to suppress groove behind the hot pressing veneer again, be medium-density plate or high-density plate, " spending in vain " phenomenon just do not occur, the yield rate of its product can be very high, not the influence that can be pressed and descending.With the press of existing conventional pressure, more exchange device and increase investment just can be produced the laminated flooring with stereoscopic visual effect expeditiously.

Its two, do not allow the less demanding groove of flatness, be subjected to the restriction of the exigent veneer of flatness, when suppressing groove separately, when the flatness of its convex tendon needn't reach veneer fully to the flatness requirement of last steel form.Therefore, it is very simple that the processing of last steel form B becomes, and expense is cheap.Go up steel form B owing to only need one again, just can with the last steel form A combination of original numerous hot pressing veneer, process and have laminated flooring various different surface structures, that stereoscopic visual effect is arranged, this is for the enterprise of in enormous quantities, brilliant structure, and increase of steel form expense almost can be ignored on it.
