Description

Non-flammable panel and its manufacturing method {The method of incombustible panel}

  The present invention relates to a method for manufacturing a non-combustible panel, which will be described in more detail, after impregnating melamine resin-shaped paper on one or both sides of a fluorinated stone panel, cutting according to specifications, and then forming a groove and a protrusion on the side to finish the treatment. It relates to a non-combustible panel manufactured and a method of manufacturing the same.

  Non-combustible building interior materials have generally been used by attaching sheets made of veneer sheet, pattern paper, and kraft paper to a substrate such as plywood or MDF. After impregnating the pattern paper in the phenol resin and melamine resin impregnation liquid, the upper part of the substrate is dried. After settling in, thermopress molding has been carried out under constant temperature and pressure.

 Conventional building boards include wood floorboards such as wood flooring boards and blocks, and stucco floorboards that have been bonded to melamine resin cosmetics on plywood, MDF, and HDF. Multi-layer laminated flooring boards are used.

  In the conventional building plate structure constructed as described above, when the floor board is absorbed by moisture due to temperature change or cleaning or the like, the contraction and expansion phenomenon are severely generated.

  In addition, due to absorption, the durability is reduced, and the drying shrinkage causes the bending phenomenon (twist) in the vertical direction, and in the left and right directions. Especially in the case of wet construction (method attached directly to the top of the structure with an aqueous solvent) due to the corruption and dry shrinkage due to moisture. Due to the bending phenomenon, there is a closed end of durability.

And another building board is formed by attaching natural colored veneer on the surface of magnesium board made of glass fiber cloth, inorganic adhesive and other mixtures that are harmless to human body with very fine magnesium oxide, and UV coating on top of veneer layer. .

 By the way, the conventional building board as described above is not easy to adhere the veneer layer, the workability and workability is lowered, as a result of which there is a defect in product quality. There have been many studies to solve this problem.

  For example, the Republic of Korea Utility Model Registration No. 20-0263325 is a phenol resin, phenol modified resin, phenol, urea modified with a woven or non-woven fabric of inorganic fibers, or an inorganic filler mainly containing ocher on the base of paper Non-combustible composite panel comprising a backing layer of a base layer, an aluminum sheet or a galvanized steel sheet impregnated or coated with a resin compound of a thermosetting resin selected from the group consisting of resins, melamine resins, melamine modified resins and melamine urea modified resins Non-combustible makeup composite panel is described,

A semi-combustible cosmetic panel containing a liquid resin composition composed of% by weight of the substrate weight 400 ~ 2000% by dry weight is described.

  Publication Nos. 20-0342637 and 20-333951 disclose flooring boards, flooring blocks, plywood, or veneered flooring boards, plywood, MDF, HDF, mainly composed of solid wood or aggregated wood. Impervious to adhered wood light or night light and master board (magnesium board), which is a highly water-resistant non-combustible material, to the back of various floorboards such as veneer stucco flooring board and veneer laminated flooring board. The floorboard which added the nonflammable board is described,

  Korean Unexamined Patent Publication No. 2003-76482 discloses a non-linear furniture interior and non-combustible paneling product manufactured by heat-treating vermiculite powder at 8000 to 1000 ° C. and compressive heating by adding a non-flammable saturated ceramic adhesive.

  Publication No. 2003-56963 discloses a non-flammable panel in which a melamine resin-impregnated paper prepared by impregnating a shape paper on one or both sides of a fluorite stone is impregnated with a flame retardant melamine resin-impregnated liquid.

  Conventional techniques as described above have a problem that the flame retardancy is low when used as a building plate burned easily in the event of a fire, or there is a problem of strength when used as a partition, which can not be used in reality.

In order to solve the above problems, the present invention does not generate toxic gases during fire occurrence, does not burn, and excellent construction properties for use as a partition or wall, can prevent noise and moisture, and also prevent bending phenomenon. The technical problem to be achieved by the present invention to provide a non-flammable panel and a method for manufacturing the same by improving the durability.

The present invention for achieving the above object comprises the steps of impregnating the shape paper in the flame-retardant melamine resin impregnation liquid and then drying to prepare the melamine resin shape paper in order to more effectively produce the non-combustible panel; Manufacturing a non-combustible board; Laminating step of laminating the prepared flame-retardant melamine resin paper on one side or both sides of the fluorine stone panel; And thermopress molding the stacked laminates; Cutting side by side to form grooves and protrusions; It relates to a non-combustible panel and a method of manufacturing the same produced in the finishing step.

In the present invention, the non-combustible board is prepared by adding 10 g of calcium carbonate, 30 g of silicon oxide, 30 g of pumice powder, 1 g of magnesium oxide, 2 g of magnesium chloride, into a stirrer and stirring, and then adding 30 g of water, and then mixing them into a mold. After molding the board, and curing for about 20 hours, to produce a non-combustible board.

If necessary, a light non-combustible panel can be prepared by reducing the amount of silicon oxide and increasing the amount of pumice.

  In the present invention, first impregnated the paper in the flame retardant melamine resin impregnation liquid, and then dried to go through the step of producing a flame-resistant melamine resin paper. The pattern paper thus obtained may be used alone or in combination of two or more layers.

  At this time, the flame-resistant melamine resin-shaped paper is used to prepare a resin impregnated amount of 50% to 70% by impregnating the paper into the flame-retardant melamine resin impregnation liquid and then dried at 90 ℃ to 120 ℃.

  When the resin impregnation amount is less than 50% in the process of manufacturing the flame-retardant melamine resin-like paper, the adhesive strength is lowered, so that the problem of peeling easily from the fluorinated stone panel occurs, when the impregnation amount exceeds 70% when considering the impregnation and drying time It takes a long time, in particular, it has to be exposed to a long time at high temperature during drying, there is a problem that can cause deformation of the paper.

Therefore, it is preferable that the resin impregnation amount is 50% to 70% by impregnating the pattern paper in the flame retardant melamine resin impregnation liquid.

  The impregnated paper is dried according to a conventional method, in the present invention was dried at 90 ℃ to 120 ℃ to prepare a flame retardant melamine resin paper (11).

 The preferred melamine resin impregnation solution is composed of 40% by weight of melamine resin, 40% by weight of urea resin, 2% by weight of methyl ethyl alcohol, 0.5% by weight of release agent, 0.5% by weight of surfactant, 10% by weight of water, and 7% by weight of methanol. To have.

  The laminating step of laminating on one or both sides of the board is performed.

At this time, the board is used to impart nonflammability.

 After laminating the flame-retardant melamine resin-like paper on one side or both sides of the board as described above, in the present invention is subjected to a step of hot pressing the laminated laminate. In this way, after the hot pressing step and the cooling step, the non-flammable paint can be manufactured using a non-flammable painter by a spraying step according to the present invention.

  The adhesive used in the present invention uses a conventional adhesive.

At this time, the thermo-pressure molding step is to heat the laminate to a pressure of 2000kg / ㎠ at 120 ℃ to 150 ℃ for 2 hours, then cooled to room temperature over 24 hours and then demolded.

  At this time, when the molding temperature is less than 120 ℃ there is a problem that the adhesive force is reduced and peeling of the paper is generated, and if it exceeds 150 ℃ it is a high temperature, so there is a problem that the deformation of the paper is caused, it is preferable to mold at 120 ℃ to 150 ℃ Do.

  In addition, if the pressurization conditions in the step of forming the laminate is less than 2000kg / ㎠ the adhesion force is reduced, there is a problem that the peeling of the pattern paper occurs, if the exceeding 25000kgf / ㎠ may cause the panel rupture and shrinkage phenomenon Because of the disadvantages, the pressurization condition is preferably 2000kg / cm 2 to 2500kg / cm 2.

In addition, when the pressing time in the forming the laminate is less than 24 hours, there is a problem in that the adhesion force is reduced and peeling of the paper is generated, and if more than 24 hours is exposed to a long time under high temperature, deformation of the paper is caused. Therefore, it is preferable to set it as 24 hours.

After being manufactured as described above, it is manufactured by processing grooves on the side in order to save construction time after cutting by specification after construction.

 The cutting method is to use a conventional running show (a type of cutting machine using a saw) and a terona (a machine for cutting a groove or a part of a side) used in the art, and to cut and form a groove or a protrusion. Specific apparatus and operating principle will not be described in the present invention.

  The non-combustible panel according to the present invention prepared as described above has the advantage of being easy to handle because of the use of boards and flame retardant melamine-shaped papers, no burning and no toxic gas generation, and excellent cutting processability and lightness. In addition, the non-combustible panel is not burned, so it is necessary to replace flame retardant or flame-retardant building interior materials, decorative plates, LPMs, and various indoor interiors.
