Description
Technical field
The present invention relates to a kind of preparation method of laminated flooring.
Background technology
Laminated flooring hangs down in Solid Wood Flooring Markets and occupies a tiny space because of its surface abrasion resistance height, price.On outward appearance and function, laminated flooring is all the time at imitation and pursuit solid wooden floor board.Chinese patent 03112761.4 disclose a kind of laminated flooring with and preparation method thereof, it has disclosed laminated flooring and has formed process and the method that chamfering is located in both sides of the edge at imitated solid wooden floor board, the technical scheme that it adopted is: lay balance paper on the lower-die steel plate of hot press, fiberboard, woodgrained paper and abrasion-proof paper, the patrix steel plate of hot press adopts the steel plate with many convex tendons, make fiberboard by the convex tendon on the patrix steel plate, woodgrained paper and abrasion-proof paper are once hot-forming, go out the groove that matches with convex tendon in the big plate disposable mold pressing in surface simultaneously, in the centerline of groove big plate is divided into platelet by sawing again, and then four sides of platelet are processed to form tenon and groove, thereby obtain the laminated flooring of lateral edges chamfering.Yet through test, we find the laminated flooring that this die pressing is produced, interior bond strength at the chamfering place is low more than 10% than the place, plane, this is because fiberboard itself has been formed with stable and fine and close structure of fibrous tissue, by having the rigid pressurization of patrix steel plate of convex tendon, can destroy its original institutional framework, reduce its intensity; Also have, the employing die pressing is produced, disposable abrasion-proof paper, woodgrained paper and fiberboard are suppressed v-depression, the distortion at V-shaped groove place is excessive, the abrasion-proof paper and the woodgrained paper cracking that can cause the surface, at present in order to satisfy production requirement, manufacturer can select all that price is high for use, the good woodgrained paper of quality and abrasion-proof paper, and this causes the production cost of laminated flooring high.
In addition, because the density of density board is higher, therefore adopt die pressing to make the chamfering floor, the patrix steel plate wearing and tearing of hot press are very fast, so the chamfer angle instability of laminated flooring, precision is relatively poor; Patrix steel plate wear block also causes the production cost of laminated flooring higher.
Summary of the invention
The preparation method that the purpose of this invention is to provide a kind of laminated flooring adopts this method can guarantee that surface grain paper and abrasion-proof paper are out of shape not quite, can ftracture, and the intensity of laminated flooring is good.
The technical solution adopted in the present invention is: a kind of preparation method of laminated flooring, it comprises the steps:
A), on fiber laminin plate, process groove one, the walking surface smooth transition of the sidewall of this groove and fiber laminin plate every specific range;
B), on the lower-die steel plate of hot press, complete balance paper successively, through processing fiber laminin plate, woodgrained paper, the abrasion-proof paper of groove, the patrix steel plate of hot press adopt with fiber laminin plate on the convex tendon that is complementary of groove;
C), make the patrix steel plate and the lower-die steel plate matched moulds of hot press, and carry out hot pressing, the big plate of the timber floor that strengthened;
D), display above-mentioned big plate;
E), above-mentioned big plate is opened bar along the centerline of each groove, obtain floor strip, at last with mortice opening around the floor strip left.
The present invention more preferably technical scheme is: at described A) in the step, adopt mode machined grooves on described fiber laminin plate of numerical control milling.
Further, the two side walls of described groove is a cambered surface, and the projection of the cross section of described groove roughly is down " people " font.
The pairing central angle of the two side walls of described groove is 3 to 45 degree.
At described C) in the step, the hot pressing temperature of described hot press is that 180 degree are to 220 degree; The pressure of the hot pressing of described hot press is 18 to 24KG/CM2; The hot pressing time of described hot press is 30 to 50 seconds.
At described D) in the step, assembly time is 3 to 6 days.
At described B) in the step, the lower-die steel plate of described hot press is adsorbed described balance paper with the vacuum suction mode.
The present invention carries out numerical control milling with CNC milling machine to fiber laminin plate earlier, mill out several blanks continuous and the rectangle band arc lower limit that shape is identical onboard, with hot bindings such as fiber laminin plate and balance paper, woodgrained paper, abrasion-proof papers, timber floor is strengthened again.Removed the secondary that fiber laminin plate is suppressed into curved surface from this method and destroyed, solved in the prior art chamfering place than the low problem of plane place's internal bond strength.Can improve the interior bond strength of consolidated floor chamfering compacting, can improve floor service life, simultaneously because mould is stressed less, and stressed everywhere evenly it is less therefore to wear and tear, and the chamfering precision is improved; The use amount of mould reduces, and then reduces cost.
The present invention compared with prior art has following advantage: the chamfering precision height of the consolidated floor mold pressing that the consolidated floor that utilizes the present invention to produce is more traditional, the interior bond strength height at chamfering place, can prolong floor service life, more traditional method production is saved mould and is taken 30%, reduced product cost, basically identical in overtesting is found the interior engaging force of edges of boards and plate simultaneously, thereby the service life of having improved consolidated floor.

B), on the lower-die steel plate of hot press, complete successively balance paper 2, through processing fiber laminin plate 1, woodgrained paper 3, the abrasion-proof paper 4 of groove 7, the convex tendon 6 that patrix steel plate 5 employings of hot press and groove 7 shapes on the fiber laminin plate 1 are complementary, as shown in Figure 2;
C), make the patrix steel plate 5 and the lower-die steel plate matched moulds of hot press, and carry out hot pressing, woodgrained paper 3 and abrasion-proof paper 4 entirely are fitted on the fiber laminin plate 1, the hot pressing temperature of described hot press is 180 degree-220 degree Celsius, pressure is 18-24KG/CM
2, hot pressing time is 30-40 second, the big plate of the timber floor that strengthened, and preferably, taking hot pressing temperature is 200～210 degree Celsius, pressure is 20～22KG/CM
2, hot pressing time is 34～38 seconds;
D), the big plate of above-mentioned laminated flooring was displayed 3-6 days;
E), above-mentioned big plate is cut bar along the centerline of each groove with multi-disc, obtain the floor strip that side has arc angling, with mortice opening or snap close around the floor strip left, be used for the connection between the floor strip at last, finally obtain the finished product laminated flooring.
Wherein, this groove can be plane or the cambered surface with the walking surface smooth transition of fiber laminin plate, for improve the comfort level of user when walking as far as possible, the preferred cambered surface of the two side walls of groove, consult shown in accompanying drawing 3 and the accompanying drawing 4, the projection of the cross section of groove 7 roughly is down " people " font, and the pairing central angle alpha of the two side walls of described groove 7 is 3 to 45 degree.
At described B) in the step, the lower-die steel plate of described hot press is adsorbed described balance paper with the vacuum suction mode.
The more traditional consolidated floor of consolidated floor that the present invention produces can improve 2-3 service life.Reduce the consumption of patrix steel plate simultaneously, improved the chamfering precision.
