The present invention relates to a method of bonding a PVA pulp sponge to other materials, and more specifically, when manufacturing a cleaning mop using a PVA pulp sponge, the upper surface of the present invention can be smoothly fastened with a handle of a cleaner. It is characterized in that the fastening the upper plate and the lower surface is integrally bonded to the non-woven fabric so as to maximize the friction with the indoor contact surface.

Conventional cleaning rags require adsorptive power or absorptivity for the purpose of wiping out or absorbing fine dust in a state in which water or water is not applied.

Therefore, most of the routine cleaning tasks are performed by wiping the ground with a broom or by absorbing dirt with a vacuum cleaner, and then using a cloth commonly referred to as a rag.

Therefore, in order to routinely clean indoors, at least two tasks such as sweeping and wiping should be performed, which is a cumbersome task.

Therefore, in recent years, indoor cleaning, which is not severely polluted, has been marketed under the trade names of magic cleaners and home sauces such as sponges made of sponges to perform sweeping and wiping at the same time.

The mop of the sponges has an advantage that it is easy to absorb moisture and can gently clean the bottom surface.

However, in order to clean the indoor floor by using the sponge-like mop, it is necessary to attach a rod-shaped cleaner handle and a fastening plate that is easy to fasten. However, since sponges have a cushioning force, it is not easy to attach the fastening plate to the upper surface, and thus, the sponges must be fastened by forming a fastening plate having a “U” shape surrounding the upper surface of the sponge and the side of the fastening plate. "The fastening plate of the shape to be combined with the handle of the cleaner.

Therefore, in order to manufacture the cleaner using the sponges, the manufacturer attaches the fastening top plate according to a separate process after the sponge forming operation, which is not only a cumbersome work process, but also a problem that the fastening parts of the sponges and the fastening top plate are not firm. have.

Therefore, an object of the present invention for solving the above problems is to manufacture a cleaning mop using a PVA pulp sponge such that the upper surface is fused to fasten the handle of the vacuum cleaner to the handle of the cleaner and the frictional force on the inner surface of the lower surface Since the non-woven fabric is integrally fused to maximize the manufacturing process in a single process, it provides a method of adhering a PVA pulp sponge to other materials to shorten the manufacturing process and increase the cleaning power by fusion bonding.

The present invention for achieving the above object is 15 to 35 weight (g) of polyvinyl alcohol (PVA) by heating at 70 ℃ for 1 hour 30 minutes to dissolve, 15 to 35 weight (g) formalin To dissolve by heating at 70 ° C. for 1 hour and then dissolving starch, such as potato and corn flour, 3 to 15 weight (g), and heating at 80 ° C. for 1 hour to dissolve, followed by 0.5 to 5 weight (g) defoamer. PVA pulp sponge dissolved by adding 0.5 to 2 weight (g) of isopropyl alcohol, and adding 0.5 to 5 weight (g) of sulfuric acid or hydrochloric acid to the cooled mixture after addition, and heating at 50 ° C. for 20 minutes. The mixture is filled with a nonwoven fabric made of cloth or urethane on the inner bottom of a mold having a predetermined shape, and a fastening plate made of iron, wood, or plastic is laminated on the PVA pulp sponge mixture. PVA pulp sponge is bonded to other materials by placing it in a kiln or a water bath in the womb and heating it with steam at a temperature of 80 ° C. to 90 ° C. for 8 hours, and then removing it from the mold and completing the dehydration process in a single process. Provide a method.

An embodiment of the present invention will be described below.

In order to manufacture the PVA pulp sponge adhesive 1 of the present invention, a PVA pulp sponge mixture 4 is prepared, and a fastening top plate 2 that can be fastened to the handle of the cleaner can be welded to the upper surface thereof, and the PVA pulp sponge The lower surface of the mixture (4) provides a method for bonding the PVA pulp sponge mixture (4) integrally fused to the interior contact surface and the nonwoven fabric (3) to maximize the frictional force to other materials.

In order to integrally fuse the fastening top plate 4 and the nonwoven fabric 3 to the PVA pulp sponge mixture 4, first, 15 to 35 weight (g) of PVA is added to a dissolution tank, and then heated at 70 ° C. for 1 hour and 30 minutes to dissolve. do.

15 to 35 weight (g) of formalin is mixed with the dissolved PVA, and dissolved by heating at 70 ° C. for 1 hour.

The mixed dissolved PVA and formalin are thickened like porridge or potato starch flour 3 to 15 weight (g) are mixed and dissolved by heating at 80 ℃ for 1 hour.

0.5 to 5 weight (g) defoamer is added to remove the air bubbles in the thickened mixture, and 0.5 to 2 weight (g) isopropyl alcohol is added to cool after the chemical reaction.

0.5-5 weight (g) of sulfuric acid or hydrochloric acid is added to the cooled mixture, which is then dissolved by heating at 50 ° C for 20 minutes.

In order to manufacture the PVA pulp sponge adhesive 1 by the PVA pulp sponge mixture 4 dissolved by the above process, a nonwoven fabric 3 made of cloth or urethane is formed on the inner bottom of the mold 5 having a predetermined shape. ), The PVA pulp sponge mixture (4) is filled thereon, and a fastening plate (2) made of iron plate, wooden plate or plastic plate is laminated thereon, placed in a kiln or water bath, and then heated to 80 ° C to 90 ° C. When heated with steam for 8 hours at the fastening top plate 2 and the nonwoven fabric 3 is fused to the upper and lower surfaces of the PVA pulp sponge (4). The PVA pulp sponge adhesive 1, which has undergone the manufacturing process as described above, is taken out of the mold 5 and completed by dehydration.

Then, the fastening top plate 2 and the bottom surface of the nonwoven fabric 3 are integrally fused to the upper surface of the PVA pulp sponge mixture 4 so that the manufacturing process is shortened and firmly fused to increase the cleaning ability. It can be.

1 is a cross-sectional view showing a PVA pulp sponge adhesive 1 according to the present invention when dissolving the PVA pulp sponge mixture 4 to prepare a PVA pulp sponge adhesive 1 and a fastening top plate 2 on the upper surface. The nonwoven fabric 3 is integrally fused and bonded by a single process.

Although the fastening top plate 2 fused to the upper surface of the PVA pulp sponge mixture 4 is not shown in the drawing, a fastening portion that can be fastened with a handle is formed and can be fastened by various methods.

In addition, the nonwoven fabric 3 fused to the lower surface of the PVA pulp sponge mixture 4 is formed of a cloth or urethane so as to maximize friction with the bottom contact surface, and the PVA pulp sponge mixture 4 when cleaning the floor. It is a structure that can remove dust and dirt easily by showing absorption power.

As described above, the present invention manufactures a PVA pulp sponge cleaning rag and the like by fusion of a fastening top plate and a non-woven fabric maximizing frictional force when the PVA pulp sponge adhesive is manufactured and bonded by a single process. Therefore, the manufacturing process can be shortened and the manufacturing work can be improved.

In addition, since the fastening top plate can be formed wide, the area of the PVA pulp sponge can be widened, and the area of the nonwoven fabric can also be enlarged, thereby maximizing the indoor contact area and the frictional force, thereby increasing the cleaning efficiency.
