Description

Non-flammability Board Treatment Difficulty Burning and Manufacturing Method Thereof}

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a flame retardant surface-treated non-combustible sheet and a method of manufacturing the same, and in particular, a flame-retardant surface-treated non-flammable for processing a surface of an inorganic or metal non-flammable sheet used to partition an interior space or to be used as a wall of an elevator. It relates to a plate and a method of manufacturing the same.

In general, non-combustible plates made of inorganic or metal materials are used for use as bulkheads or walls of elevators. These non-combustible boards cannot meet the tendency of high-end interiors by themselves. The surface was finished by applying paint or vinyl coating.

However, since the decorative effect of the paint coating or vinyl coating as described above is a simple one, it has not responded to the trend of improving the interior of the interior, and in recent years, it is a situation that additional interior materials are additionally installed on the surface of such a non-combustible plate material, which is cumbersome for additional construction. And facilities cost a lot, there is a problem that the indoor space is reduced.

In addition, when the interior of the decorative material for the decoration after the addition of the non-combustible sheet material is that most of the interior material is flammable, there is a problem such as causing suffocation by generating toxic gas in the event of fire.

In view of the above conventional problems, an object of the present invention is to heat-bond adhesive pulp kraft paper and titanium paper impregnated with a flame retardant resin to an incombustible plate made of an inorganic or metal material, thereby maintaining a non-combustible sheet material while maintaining a beautiful decorative effect. To provide a flame retardant surface-treated non-combustible sheet and a method for producing the same.

In order to achieve the above object, the present invention impregnates a pulp kraft paper in a resin solution containing alkydphenol as a main component so that the resin content is 40% to 42%, and then the temperature of 110 ° C to 130 ° C and 10m / min to 12m / min. Drying the inorganic or metallic sheet and the resin-impregnated pulp kraft paper and the resin-impregnated shape paper in a separate process, and then laminating it at a temperature of 140 ° C. to 150 ° C. and a pressure of 30 kg / cm 2 to 50 kg / cm 2. A flame retardant surface-treated non-combustible plate material and a method for producing the same, which are pressurized and heated for 40 to 50 minutes and then slowly cooled to 30 ° C. to 40 ° C. at room temperature, are proposed.

As a result, the present invention can obtain a beautiful interior decoration effect even if the interior material is not added to the inorganic plate or the metal plate.

Referring to the configuration and operation of the present invention as described above in detail as follows.

According to the present invention, a pulp kraft paper (12) impregnated with a resin solution containing alkydphenol as a main component on an inorganic or metallic plate (11) is impregnated thereon, and a shape paper (13) impregnated with a melamine resin or coated with a melamine resin. And then thermoforming by high temperature and high pressure.

That is, in the present invention, in order to enable the surface treatment to obtain the flame retardant performance and the beautiful decorative effect on the surface of the inorganic or metallic plate 11, first, the pulp kraft paper 12 of 70 g / m ² to 80 g / m ² Prepare.

Next, a resin for impregnating the pulp kraft paper 12 should be prepared. To this end, the present invention is a mixture of 50wt%-60wt% alkyd phenol and 37wt%-37.5% formalin 40wt%-50wt% in a 1.0 mol to 1.1 mol state, 2wt% to 3wt% silane, 25% to 27% 0.3% to 0.4% of ammonia water was added as a catalyst and stirred at a temperature of 60 rpm to 70 rpm at a temperature of 90 ° C to 95 ° C.

In this way, it becomes a cloudy state, and when it dehydrates by a heating method in this state, it reaches a transparent state.

At this time, 99% to 99.9% of methanol as a solvent is added so that the viscosity can be 50cps to 60cps to complete the impregnation resin for impregnating pulp kraft paper.

Subsequently, the impregnating resin is placed in an impregnation tank at 15 ° C. to 20 ° C., and the prepared pulp kraft paper is impregnated to a resin content of 40% to 42% and dried.

At this time, the drying temperature is to be 110 ℃ to 130 ℃, through a drying furnace at a speed of 10m / min to 12m / min adjusted to a flow rate of 4% to 6% and then cut to the desired specifications.

Subsequently, impregnated titanium papers should be prepared, and an impregnating resin for this purpose is prepared by the following process.

The impregnated resin solution was aged from 14wt% to 16wt%, 99% methanol to 8wt% to 10wt%, PVA 2wt% -4wt% into the reactor and stirred at 60rpm to 70rpm at 60 ℃ -65 ℃ for 60 minutes to 80 minutes. It is made into the completely dissolved state that a grain is not seen.

37% to 37.5% formalin solution 30wt% to 32wt% TEA (TRI-ETHYL AMIN) methanol 2wt% to 3wt%, DEG (DE ETHYL GRICOAL) 2.6wt% to 2.8wt%, PTSA 2wt% to 3wt% The mixture was heated and stirred at 60 rpm to 70 rpm in a state of 86 ° C. to 90 ° C., and aged for 60 to 70 minutes until it became a transparent state.

In addition, while diluting the resin sample obtained in this way with water, the reaction state is observed by making them ratio of water 1: resin 4 to water 1: resin 6. At this time, when the milk is turbid, it can be judged that the resin preparation is completed. In addition, such a resin sample reaction test may be omitted in a commercial production line, and 0.3 wt% to 0.5 wt% of phthalic anhydride, 0.7 wt% to 1 wt% of glycerin, and 0.3 wt% of oleic acid as a release agent to the resin thus obtained. To 0.5wt% is added and cooled to reach 30 ℃ to 35 ℃. The impregnated resin thus prepared was placed in an impregnating tank at 15 ° C. to 20 ° C., and the printed wood grain or various desired patterns were printed, and the resin was impregnated with a roll of titanium paper having a thickness of 60 g / m ² to 80 g / m ^2. The amount of resin is adjusted to take out 50% to 53%, and dried in a drying furnace.

The drying furnace at this time is such that the internal temperature is 110 ℃ to 150 ℃, passing through a drying furnace of 30m to 60m at a speed of 8m / min to 11m / min. The impregnated paper prepared in this way is cut to a desired pattern shape by a laser or decorated in advance by laser to obtain decorative paper in a desired shape in order to decorate using the inlay technique.

The shape paper obtained by this process is placed on a pulp kraft paper placed on an inorganic plate or a metal plate and formed by pressing and heating for 40 to 50 minutes at a temperature of 140 ° C. to 150 ° C. and a pressure of 30 kg / cm 2 to 50 kg / cm 2 in a multi-stage press. Subsequently, when it cools slowly so that it may become 30 degreeC-40 degreeC at normal temperature, the nonflammable plate material 10 will be obtained.

In fact, in order to increase productivity, the non-flammable sheet material 10, the pulp kraft paper 12, and the shape paper 13 are arranged symmetrically with the metal plate as the boundary between the upper and lower press hot plates. Heated and pressurized under the conditions, it was possible to manufacture a plurality of non-combustible sheet material in a single process, thereby improving the productivity.
