The present invention relates to a manufacturing method for producing flooring material and flooring material having a high internal combustion effect, and in particular, a method of deeply impregnating the interior of the wood flooring wood by dipping rather than applying a flame retardant material to the surface of the wood flooring wood. And the flooring material thus prepared is added to each step of the manufacturing method to facilitate the impregnation, and thus the flooring material thus prepared is a flooring material having a significantly improved flame retardancy and non-combustibility. It is flooring.

In general, floor coverings have been made of wood, which is a very old technique of prefabricated floor coverings.

However, in the case of such flooring material, when a fire occurs, a large amount of toxic gas is discharged and burned, and the cause of killing a resident's life is not caused by fire and heat, but is caused by this gas. Therefore, in the use of all building materials these days, the effects of the flame retardant and non-flammable of the material is treated essentially. As a result, these waves are being replaced with nonflammable and flame retardant materials for flooring.

Due to this tendency, the wood flooring material made of wood has a high burning property and is used by applying a flame retardant material or a non-flammable material on its surface. However, these blind flame retardant floorings are not really profitable if a big fire is actually thrown and the fire is emitted. In other words, if some surface treatment is collapsed, it is burned because it is the same as general wood flooring.

The present invention, which solves the above problems, relates to a manufacturing method for producing a flooring material and a flooring material having a high internal combustion effect. In particular, the interior of the wood flooring wood is not dipped but applied to the surface of the wood flooring wood. Using the method of deep impregnation, the process of facilitating this impregnation at each step of the manufacturing method is added, and thus the flooring material produced is a flame retardant wood flooring material, characterized in that the flooring material of the flame retardancy and non-combustibility is significantly improved. It is intended to provide a method and wood flooring thereof.

Accordingly, the present invention provides a method for producing a flooring material, the first step: enlarging the wood voids by putting the wood flooring in a vacuum; Second step: steaming the wood floor wood using steam to soften the wood grain to penetrate the flame retardant material; Step 3: lowering the temperature of the heated solid wood floor to 10-50 ° C. and vacuuming again to enlarge the voids in the wood; Step 4: dipping the wood floor wood into a flame retardant material; Step 5: pressurizing the impregnated hardwood flooring wood using high pressure; Step 6: heating the wood floor wood with steam to deeply impregnate the flame retardant material; A seventh step: a dewatering step of washing the impregnated hardwood floor and extracting water; Eighth step: drying to a temperature of 10-40 ℃ through natural drying or dryer; The ninth step is to cut and complete the shape as flooring material for assembling, so that flame retardant material is impregnated deep inside the wood flooring wood to provide flame-retardant wood flooring material manufacturing method that improved flame resistance and non-flammability even in heavy flames. I would like to.

In another aspect, the present invention is a floor covering made of solid wood, consisting of a solid wood layer located at the bottom end, a flame retardant adhesive layer applied to the top of the solid wood layer, and a solid wood layer in close contact with the top; 25-55 parts by weight of water, 25-40 parts by weight of ammonium lactate, 5-15 parts by weight of one or more ammonia and ammonia phosphate, 3-8 parts by weight of phosphate ester, TCEP 3 -6 parts by weight, 2-6 parts by weight of aluminum hydroxide, and magnesium is solid wood flooring impregnated with liquid flame retardant produced by adding a lacking part by weight in the mixture of the above materials; It is to provide a flame retardant solid wood flooring material having an insertion protrusion and an insertion groove formed on both left and right ends of the wood floor.

In addition, the flooring material made of solid wood, consisting of a plywood layer located at the bottom end, a flame-retardant adhesive layer applied to the upper plywood layer, and a solid wood layer in close contact with the top; 25-55 parts by weight of water, 25-40 parts by weight of ammonium lactate, 5-15 parts by weight of one or more ammonia and ammonia phosphate, 3-8 parts by weight of phosphate ester, TCEP 3 -6 parts by weight, 2-6 parts by weight of aluminum hydroxide, and magnesium is solid wood impregnated with a weak flame-retardant material produced by the input of a weight part deficiency in the mixture of the above materials; It is to provide a flame retardant solid wood flooring material having an insertion protrusion and an insertion groove formed on both left and right ends of the wood floor.

The present invention relates to a method for producing flooring material and flooring material produced by the method. Therefore, the unique manufacturing process and characteristics of the present invention will be described in detail with the drawings.

As shown in Figures 1 to 4, the present invention is the first step: the wood floor wood is put into a vacuum to expand the air gap in the wood. In other words, the already manufactured wood flooring wood is put into a vacuum. This expands the pores so that impurities that have penetrated the numerous pores inside the wood grain can escape. Of course, experiments proved that many impurities actually escaped from this process.

Next, the present invention is a second step: the wood flooring wood is steamed using steam to smooth the wood grain for penetration of the flame retardant material. That is, the first step is to steam at a high temperature using steam on the wood flooring wood, the pores of the wood grains are expanded. This process softens the texture of the wood and enlarges the pores to allow the impurities inside to escape. When water is supplied at a high temperature, the wood floor wood expands by itself according to the temperature change, and the expansion causes the pores inherent to be wider. Therefore, the dust and other impurities existing in the interior are released.

And the third step of the present invention is to lower the temperature of the heated solid wood flooring wood to 10-50 ℃, and then subjected to a vacuum process to enlarge the air gap in the wood. In other words, the temperature of the heated solid wood floor using natural drying or a cooler to drop. This shrinkage process is to reduce the voids once by densifying the wood grain so that the impregnated flame retardant can be densely penetrated during the impregnation of the post-processing flame retardant. At this time, the temperature is most preferably dropped to about 10-50 ℃. If it is too low, there are many problems in performing the post-processing step, and the temperature above 50 ° C is meaningless because the actual void is not narrowed. Of course, after that, the wood floor is vacuumed again to remove the impurities in the voids. When the vacuum is maintained in this way, the voids inside the wood grain are enlarged and appear to be enlarged, thereby causing the impurities inherent to escape.

Furthermore, the present invention is the fourth step: the wood floor wood is dipped in flame retardant material impregnated. In the present invention, the step of flame retardant dipping is the most important step. According to this step, the flame-retardant material is impregnated deep inside the wood grain of the parquet wood. Of course, even if the firewood is pulled by the wood floor, it does not catch fire and has the effect of non-combustible flame retardant and smoke.

Let's take a closer look at the composition of the flame retardant, a composition that produces the effects of this flame retardant and flame retardant. That is, this flame retardant material is 25-55 parts by weight of water, 25-40 parts by weight of ammonium lactate, 5-15 parts by weight of one or both of ammonia and ammonia phosphate, and 3-8 parts by weight of phosphate ester And, 3-6 parts by weight of TCEP, 2-6 parts by weight of aluminum hydroxide, and magnesium are liquid flame-retardant materials produced by adding a short part by weight in the mixture of the above materials.

About 25-55 parts by weight of the injected water is administered to facilitate penetration into the fiber of the tree and for sufficient dissolution of other components. And ammonium lactate is included in the 25 to 40 parts by weight, the material required for flame retardant and non-combustible. Wood impregnated with this material will not generate soot.

And about 5-15% by weight of ammonia and ammonia phosphate. The ammonia and ammonia phosphate also have the effect of flame retardant and nonflammable. Only 5-15 parts by weight of ammonia may be included, and 5-15 parts by weight of ammonia alone. Of course, the ammonia and ammonia phosphate may be mixed with each other in an appropriate ratio of 5-15 parts by weight.

In addition, the flame retardant material of the present invention includes a phosphate ester, which helps the flame retardant material to easily penetrate into the internal grain of the wood grain of wood. In other words, the flame retardant material can be impregnated more than when penetrating into the interior of the solid wood timber, and serves to penetrate deeper.

In addition, the present invention includes 3 to 6 parts by weight of TCEP, in the case of TCEP helps to mix well between components, and serves to facilitate the intrusion of flame retardant materials into the internal pores of wood grains, such as the lean acid ester. .

In addition, the flame retardant material of the present invention contains about 2-6 parts by weight of aluminum hydroxide. This aluminum hydroxide also has the effect of non-combustible and flame retardant, and plays a role of inducing the wood grain more densely. Therefore, the impregnation becomes more robust and see the effects of non-combustible and flame retardant.

Finally, magnesium is used in an amount by weight deficiency in the mixing of the waters. Magnesium also has the effect of maintaining the density of wood grains more densely and plays a role to penetrate very deeply into the wood binding voids.

As described above, the process of impregnating the interior of the wood flooring wood with a flame retardant material consisting of a very unusual combination is completed and the present invention is a step 5: pressurizing the impregnated wood flooring wood using high pressure. Rough This step allows the impregnated flame retardant to penetrate more stably into the interior voids of hardwood flooring, and is pressurized using pneumatic pressure to secure its position in the voids.

And the present invention is the sixth step: heating the wood floor wood with steam to go through the step of deeply impregnated with the flame-retardant material. The wood floor pressurized using pneumatic pressure is heated by using steam, and a large number of pores existing inside the wood grain are widened. Therefore, the flame-retardant material impregnated at the previous stage in this process is impregnated to a greater extent, so as to impregnate deep inside the wood grain. In other words, it penetrates the cell wall of the tree and gets into the cytoplasm very deeply. Therefore, according to this deep impregnation flooring of the present invention is excellent in the effect of flame retardant and non-combustible.

Meanwhile, the present invention is subjected to the steam heating step, step 7: washing the impregnated parquet wood and undergoes a dehydration step of draining water. That is, after the impregnation of the flame-retardant material is finished using the water flowing down the wood flooring timber is washed cleanly and then goes through the step of dehydration to drain the water. Of course, it is also possible to use the method of immersing and storing in stored water, but to avoid the additional rubbing or rubbing work by washing solid wood with flowing water, it is a method that does not damage wood grains. And the wood floor in this washed state goes through the step of dehydration to drain the water. At this time, the dehydration method can be used using centrifugal force or high temperature drying and freeze drying.

Furthermore, the present invention undergoes the eighth step: drying at a temperature of 10-40 ° C. through natural drying or a dryer. This is to facilitate the cutting operation to be continued later to dry the dehydrated wood flooring wood using a natural drying or a dryer. Natural drying is a method of random drying by leaving solid wood in an open space, which takes a lot of time, and it is preferable to dry the dryer at a temperature of about 10-40 ° C. Cases may occur.

And the present invention finally finishes the ninth step: cutting and completing the form as a floor covering for assembly. That is, the step of cutting to form the insertion protrusion and the insertion groove in the left and right sides of the flooring. Solid wood for impregnation is wide plate wood. It is difficult to assemble such wood entirely on the floor, so this wide wood is cut into a long rectangular shape. And the assembly is easy to form the insertion protrusion and the insertion groove in the left and right side in the state formed in this way.

Therefore, the present invention is to provide a flame-retardant wood flooring material in which the flame-retardant material is impregnated deep inside the wood flooring wood to improve the flame resistance and non-combustibility even in the harsh flames.

Here, the wood floor wood 50 of the first step, as shown in Figure 1, there is a wood layer 10 located at the bottom end, there is a flame-retardant adhesive layer 20 applied to the top of the wood layer (10). In addition, it consists of a solid wood layer 30 in close contact with the top. That is, the thick wood is laid at the bottom, and the top plate is made of the wood layer 10 to the top in the state where the flame-retardant adhesive is applied to the top and bonded to the top.

By the way, the wood floor timber 50 of the present invention can be produced in other forms. That is, the wood layer 10 formed at the lower end is used to change the plywood layer 40. In other words, there is a plywood layer 40 located at the lowermost end, and a flame-retardant adhesive layer 20 applied on the plywood layer 40 is formed. In addition, it refers to the wood flooring wood 50 made of a solid wood layer 30 in close contact with the top.

In the present invention, steaming conditions of the second step may be limited as follows. That is, steaming for 10-100 minutes at a temperature of 20-200 ℃. This condition is an empirical rule obtained by the applicant of the present invention, and it has been obtained that maintaining this temperature and time is a measure of impregnation.

Further, the pressurization condition of the fifth step is preferably pressurized for 2-10 hours at a pressure of 1-20kg / cm ² . The reason for defining this condition is, of course, similar to the steaming stage of the second stage described above.

Meanwhile, the present invention may further include a process of applying general UV coating or flame retardant UV coating 55 to the surface after the drying step of the eighth step. In fact, it is common to apply a separate coating to increase the durability without being injured by the wood grain formed on the surface of the floor. Therefore, the present invention is to apply a general UV coating or flame retardant UV coating 55 on the top of the top plate as shown in the figure.

In addition, the present invention in the flooring material made of solid wood, the bottom of the solid wood layer 10, the flame-retardant adhesive layer 20 applied to the top of the solid wood layer 10, and the solid wood layer 30 in close contact with the top ); 25-55 parts by weight of water, 25-40 parts by weight of ammonium lactate, 5-15 parts by weight of one or more ammonia and ammonia phosphate, 3-8 parts by weight of phosphate ester, TCEP 3 -6 parts by weight, 2-6 parts by weight of aluminum hydroxide, and magnesium is a solid wood flooring (50) impregnated with a weak flame-retardant material produced by adding a lacking part by weight in the mixture of the above. And it is a flame-retardant solid wood flooring material in the form of the insertion projections 51 and the insertion grooves 52 are formed on both left and right ends of the wood flooring wood (50). That is, the flooring material itself impregnated with the above flame retardant is also a subject of the present invention.

By the way, the important point here is that the bottom of the wood to form the wood flooring timber 50 is used for the solid wood.

And the flooring material of the second embodiment which is impregnated using the same flame retardant material as in the above-described embodiment, but the structure forming the lowest floor in forming the wood flooring 50 is somewhat different.

That is, in the flooring material made of solid wood, the bottom of the plywood layer 40, the flame-retardant adhesive layer 20 applied to the top of the plywood layer 40, and the solid wood layer 30 in close contact therewith Done; 25-55 parts by weight of water, 25-40 parts by weight of ammonium lactate, 5-15 parts by weight of one or more ammonia and ammonia phosphate, 3-8 parts by weight of phosphate ester, TCEP 3 -6 parts by weight, 2-6 parts by weight of aluminum hydroxide, and magnesium is the wood flooring material 50 impregnated with a weak flame retardant produced by adding a lacking part by weight in the water mixture. In addition, the flame-retardant wood flooring material formed with the insertion projections 51 and the insertion grooves 52 on both left and right ends of the wood flooring wood 50 is the subject of the present invention.

As described above, the present invention is useful to be used as a lining agent because it does not burn easily and does not emit smoke or odor even if exposed to a flame, because it impregnates the flame-retardant material deep inside the wood flooring wood.
