Description

Crematorium {omitted}

As flooring materials for living rooms and stores in houses, exhibition halls and performance halls, stone materials such as marble, vinyl floorboards, flooring materials made of solid wood, and flooring materials that are bonded to plywood are commonly used. This is a promising field.

However, the traditional stone materials do not fit well with our legislative culture, and are not suitable for residential use, and are limited to exhibitions and lobbies.

In addition, the vinyl-based, such as jangpan made of a very harmful component to the human body not only has a problem in use, but also in the summer when using the moisture did not fall out of the sticky or odor, such as hygiene problems.

In order to solve the above problems, a fur ring made of pure wood is used, which is very weak to moisture, and when exposed to moisture, warping or warping occurs, making it impossible to use it. There were also safety issues, such as damaging the socks or, if severe, getting thorns in the feet.

Moreover, since it was made of pure wood, the cost of materials and processing was inevitably high, which also undermined natural forests in order to obtain high quality materials.

Thus, similarly to the present invention, the floorboard is made of glued veneer on a plate made of plywood, but the prior art is a predetermined floorboard by adhering the veneer cut to a predetermined standard according to the short length of the plywood. It was made by cutting to the standard and finishing the coating in the middle and top.

However, in the prior art as described above, the size of the plywood for adhering the veneer is formed in a width of about 2100mm x 900mm, and in order to meet the normal floorboard standard, the veneers cut in advance so as to be 900mm in length are arranged in the lengthwise direction of the plywood. This is done.

This requires a lot of time and personnel for the bonding, and even if the pre-cut veneer is slightly cut off at the time of bonding, even if the X-axis and Y-axis do not fit a little, it is cut out of the part where the veneer is glued at the time of cutting and enters the plywood, resulting in poor image quality There has been a closure that has occurred and becomes unusable.

In addition, even in the coating that must be performed in order to add protection and aesthetics of the veneer glued to the plywood, it is conventionally performed after cutting, which also acts as an increase factor of a lot of time, manpower, and manufacturing cost.

In addition, in the prior art, when the veneer is adhered to both sides of the plate, the veneer is first adhered to one surface by hot pressing and then waited for the plate to cool, and then the above steps are repeated again to reattach the veneer to the back to hot press. It has been done as a deadline.

However, according to the above, even though the veneer having the same shrinking force on both sides of the plate, the moisture content of the surface that is bonded to the past and the surface where the adhesive is finally made is naturally different from the warpage occurs.

The present invention is to solve the above problems, by forming a decorative material on a normal plate, and after the coating on the length and width of the long plate in the state where the decorative material is formed is cut to a predetermined floorboard standard .

Therefore, the efficiency of the work and the manufacturing cost can be reduced at the time of bonding the veneer materials such as veneer and painting the floorboards.

In addition, in adhering the decorative material such as veneer to the plate, in order to minimize the conventional warpage, such as by pressing the decorative material on both sides of the plate, the heat of the upper and lower hot plate by the heat press made of the same configuration, By pressing, the decorative material is adhered to both sides of the plate to minimize time, manufacturing cost, and warping of the product.

One embodiment

In this embodiment, it is characterized by having the decorative material 20 and the coating layer on both sides of the top and back of the floorboard,

This may add to the aesthetics of the floorboard, and the floorboard may prevent bending or warping due to changes in tensile force or moisture content of the stucco 20, and may shorten working time and reduce manufacturing costs.

In order to achieve the above object,

Bonding the peeled pattern wood pieces on both sides and (S1),

Hot pressing the sheet material bonded on both sides of the veneer (S2),

(S3) the process of painting on both sides of the floor board

A step of temporarily cutting the plate (S4),

It consists of the process (S5) which forms and completes a joining groove part in the said board | plate material, and it demonstrates in detail for each process.

(Process of bonding the peeled pattern wood piece to both sides)-(S1)

First, as shown in FIG. 2A, the urea resin, the melamine resin, the emulsion resin, the flour, and the like are formed on one surface of the plate 10, that is, plywood, fibrous compression reinforcement, or wood, by the same method as in the related art. In order to apply the adhesive 30 to be mixed or the general adhesive 30 of the proper component, the adhesive 30 is pumped to one roller 32 (upper roller in the drawing) of the spray roller 31. In the state, the plate 10 enters the spreader roller 31 so that the adhesive 30 is applied to one side of the plate 10 (upper surface of the wooden board on the drawing).

Alternatively, the adhesive 20 may be sprayed and applied by spraying, and the method or method of applying the adhesive 30 to the plate 10 may be applied by other methods.

In this way, the decorative material 20 that can fully exhibit the pattern, pattern, color of the wood grain (20; veneer, printing paper, impregnated paper, impregnated wood, bamboo) on one surface of the plate 10 coated with the adhesive 30 , Cosmetics, which are made of cork, Korean paper, pattern printing, and the like, in order to impart an aesthetic sense to a normal plate, by the adhesive 30 applied to one surface of the plate 10 as shown in FIG. 2B. Make it temporary.

The temporary adhesion means that the adhesion is performed as the urea resin, which is a heat-curable resin, is hardened by Emeljohn bond, which is a naturally-dried bond, and flour, as a bonding step just before hot pressing.

In consideration of the characteristics of the adhesive 30, the adhesive 30 is first applied to the surface to be bonded is formed by the weight ratio of urea resin 5.5: Emel John Bond 0.5: wheat flour 4, such a component ratio is after The adhesive 30 is hardened quickly so that the secondary backing can be made smoothly, and during the heat press press 40, the hardened adhesive 30 reacts quickly by heat and is cured by the adhesive. ) To match the curing time.

In order to achieve the above object, the composition ratio of the adhesive 30 to be applied to the back is compounded at a weight ratio of urea resin 6.5: emulsion bond 0.75: flour 2.75, which slows down the curing time of the adhesive 30 somewhat. Anyone with knowledge of this can easily recognize and implement it.

In addition, due to the nature of the makeup flooring plate (1) is often exposed to moisture, it is possible to form an adhesive by mixing melamine resin with good water resistance.

As such, the plate 10 to which one side of the veneer 20 is temporarily bonded is loaded until the adhesive 30 hardens at room temperature, and usually about 30 minutes is the best time.

The plate 10 undergoes such a process, even if it is before the hot pressing (40), so that the veneer 20 is not damaged due to the hardened adhesive, so that the veneer 20 is undamaged or transported from the plate 10. do.

By repeating the previous process to the plate 10, the adhesive 30 is applied again and the veneer 20 is adhered to obtain the plate 10 to which the veneer 20 is temporarily bonded to both sides as shown in FIG. 2C. do.

(Heat Pressing Process-S2)

As such, after temporarily attaching the veneer 20 in which various patterns, patterns, colors, etc. are expressed on both sides of the plate 10 by the adhesive 30, spraying the veneer 20 so as to maintain sufficient moisture. By spraying using such as to prevent the overlapping or cracking phenomenon of the veneer 20 (20).

It is necessary to maintain this moisture, the normal veneer 20 obtained by peeling the solid wood will usually exhibit a water content of about 20 to 35%, in the case of the temporary glued veneer 20, the adhesive 30 is hardened while the veneer ( 20) to take away the moisture thereby the veneer 20 is dried.

This dehydration of the veneer 20 will cause the wood to shrink, which will indicate that the original veneer 20 will be reduced to a considerable width.

Although the ratio of the decrease due to the decrease in the moisture content of the veneer 20 is small in the longitudinal direction of the wood ball, the width direction of the wood ball will show a difference as much as about 10% of the total ratio.

If the pressurizing process is performed without supplementing the water content to the veneer 20, the overlapping portion where the veneer 20 and the veneer 20 meet will not be connected to each other and the plate 10 will be opened to the naked eye. In addition, even if the part is concealed, it appears to be indented by the thickness of the veneer 20, causing a problem of deteriorating the aesthetics of the product.

Therefore, during the operation of the hot pressing 40, the adhesive 30 reacts by heat, and after the solidified fluid is fluidized again, the moisture 30 must be supplied to prevent shrinkage of the veneer 20 until it is cured by heat.

In this case, the adhesive 30 of the first bonded surface is supplied with more moisture because it takes more time to melt and harden, and later, the adhesive 30 of the bonded surface will immediately react to harden. At least.

The pressurized temporary adhesive plate 10 subjected to the above process is pressed into the hot pressing press 40 as shown in FIG. 2D, and the pressing operation is performed. The configuration of the hot pressing press 40 according to the present invention consists of a plurality of hot plates 44, In the hot press 40 composed of 45, the heat supply temperature of the upper hot plate 44 and the lower hot plate 45 is configured to be the same.

That is, as the reason for bending or bending of the plate 10 occurs,

①by the contraction force of the pattern shepherd itself,

② deformation due to the components of the adhesive,

③ deformation by heat,

④ It can be largely divided into deformation due to the difference in moisture content.

The present invention is intended to prevent deformation due to the difference between the heat and the moisture content rate, and the difference in the strain rate according to the heat and moisture content rate is pointed out as the main cause of the bending phenomenon of the plate (10).

In order to increase the adhesion between the stud material 20 and the plate 10 in the conventional hot press 40, the cushioning material 43 or the stainless steel plate is provided on the top or back side of the hot plates 44 and 45,

Therefore, even if the heat source is properly supplied to the hot plates 44 and 45, the adhesive 30 is hardened by heat, and heat is transferred to the plate 10 to be bonded to each other to cause bending or banding. I did not do both sides at once.

In detail, the surface temperature of the hot plate 44 of the upper press portion 41 in the state that the cushioning material 43 of the hot press portion 40 is not attached to the hot plate 44 is maintained at 80 to 110 degrees Celsius. By the heat is transferred to one side of the plate 10,

In the hot plate 45 of the lower press portion 42, the temperature of the heat transmitted to the plate 10 by the heat conduction lowering effect of the cushioning material 43 is lowered from the heat plate 44 of the upper press portion 41. It is delivered at about 60 ° C to 80 ° C, lower than the temperature delivered to).

In this state, when the plate member 10 comes into contact with the hot plates 44 and 45 and gradually pressurizes and heats as the lower press 42 of the hot press portion 40 rises, the upper press transferring relatively high temperature Moisture contained in the upper surface side of the plate 10 which is in contact with the hot plate 44 of the (41) evaporates, so that the plate 10 is retracted and the one side of the plate 10 (that is, the surface located on the upper press side) itself The shrinkage phenomenon occurs.

On the contrary, the back side of the plate 10 which is in contact with the hot plate 45 of the lower press 42 which is relatively low temperature is transmitted by the cushioning material 43 or the like is relatively in the plate 10 by the cushioning material 43. As the effect of evaporation of moisture is less, the relatively less moisture is dehydrated. Therefore, the plate is concave immediately after hot pressing by a shrinkage ratio (ie, different moisture dehydration rates on both sides of the plate) than the shrinkage ratio of the front side of the plate 10 (Fig. 4). The bent state is added to proceed.

Therefore, the present invention, as shown in Figure 5, without installing the cushion member 43 or the stainless plate of the hot plate 44, 45, the heat of the hot plate consisting of the upper portion 44 and the lower portion 45 to the plate 10 intact By being delivered, double-sided bonding, bending and banding could be eliminated at once.

In order to do so, it is well known that both surfaces of the hot plates 44 and 45 should be formed evenly.

Therefore, heat is conducted to the hot plates 44 and 45 of the upper and lower press portions 41 and 42 of the hot press portion 40 (in this case, the conduction of the heat is supplied by the same temperature, respectively). The heat conduction is performed by steam, oil, electricity, or the like, and the surface temperature of each of the hot plates 44 and 45 of each of the heat press parts 40 is maintained such that 80 ° C to 110 ° C according to the type of adhesive member. It is desirable to.

Due to the heat conducted by the heat pressure process, the fiber and moisture of the wood constituting the plate 10 and the adhesive 30 for bonding the same are obtained by the same heat transferred to both sides of the plate 10, By the heating in a straightened state by such a work, the veneer 10, which is temporarily bonded to both sides, is made by finishing the adhesive 20 on both sides with one heat press pressing 40. You will be able to stay straight.

(Step of painting on both sides of flooring board)-(S3)

As a step of coating on one side or both sides of the floorboard decorative plate (hereinafter referred to as a makeup plate) that has undergone the step (S2) (S3), it is best to apply the coating by a known U / V method. desirable.

The painting by the known U / V method is

As the makeup plate 2 is transported along the cone bare line where the direct rollers and reverse rollers are repeatedly arranged, the paint rollers are first coated with the direct rollers and the reverse rollers which are pumped with woodsila, When the paint is dried by U / V irradiation, the dryness and smoothness are obtained by passing through the direct roller and the reverse roller, which are pumped with the wood and sanding thread, and finally, the second drying is U / V. It means that paint is dried by V irradiation.

At this time, Woodsila paint may be a soft epoxy type paint with good eyesight and swelling properties. Sandinga paint uses a soft paint with excellent abrasiveness and excellent transparency to obtain transparency and smoothness of the coating film. good.

When the above-mentioned single coating cannot obtain the desired degree of coating film or smoothness or the desired properties, the process is repeated partially or in combination.

After that, as a feature of the present invention , the finish top coating, which was conventionally performed in the last step after completing the integral processing with a predetermined floorboard, is carried out together in the state of the decorative plate 2.

This is also done by the U / V method.

At this time, the top coat is characterized by the flooring board (1) used as a flooring material, and should be characterized by its hardness and ductility, and furthermore, the dirt or graffiti is easily erased or manufactured by adding a specific fragrance. You could do it.

In addition, since the urethane and lacquer series have good transparency, the surface gloss is classified into a gloss, semi-gloss, and matte according to the consumer's taste.

If necessary, in order to express the soft and old-fashionedness of the painted surface, paint the plate (2) with the final top coat on the upper surface with a paint made of transparent color such as brown or orange on the paint, and then dry it by natural drying or heat source. Drying is done by finishing the top coat.

(Process of temporary cutting cosmetic)-(S4)

As shown in FIG. 2A, the decorative plate 2 subjected to the above process is first cut into a length corresponding to a predetermined length of the decorative parquet plate 1 (eg, 800 mm), and then the predetermined width of the floor plate (eg, 100 mm). It is made by cutting.

The specification of the cutting is to include a processing dimension for forming the coupling groove 50 in the next step (S5) is usually given equal to the side of the slope, or the female portion 51 is given a small, which is male This is because the portion 52 is formed by cutting the surface portion into the upper surface and the back surface, whereas the female portion 51 forms the groove inward by cutting the central portion of the decorative plate 2.

Usually, the processing dimension of one side is about 5 mm is most preferable.

Since the cutting process is installed on the entire sheet of material (10; eg: 1220mm X 2440mm) and the decorative material 20 and the paint as a whole, unlike the prior art method, there is almost no defect or loss when cutting It is a feature of.

(Process of forming and forming the overlap grooves on the cosmetic board)-(S5)

This process relates to the process of forming the coupling groove 50 as shown in Figure 3 on the parquet 1 after the process (S4) as the final process (S5) of the present invention.

In the known floorboard, the coupling groove 50 has a rounded shape, which causes the floorboard to be lifted or sounded due to the play of the fitting portion at the time of joining each other, so that the gap is easily visible even when the gap is slightly separated. It became a problem.

The overlap groove 50 of the crepe floor 1 of the present invention is characterized in that it constitutes a right angle groove 50 of the diagonal line to compensate for this problem.

This configuration is characterized in that the same fit is always made regardless of the inaccurate fit of the overlap groove 50 when joining the parquet floor (1).

One embodiment of the present invention is described only a part, it is possible to easily carry out other embodiments without departing from the technical configuration and spirit of the present invention, the purpose or effect of the invention is easily carried out by those skilled in the art You can see that you can.

According to the present invention, first, the entire stucco 20 is formed on the plate 10 having a large area, and if necessary, after coating, the cutting and processing are performed to obtain a plurality of decorative parquet plates 1. Reduction of time, personnel and manufacturing costs can be expected.

Also, in forming the stucco 20, the stub 20 is formed on both sides of the plate 10 in advance, and then the press 40 works once by the hot pressing 40 to which the same heat is transferred. As the double-sided adhesion is made, the effect will be greater.
