Description

Non-slip mat prepared by using the pressure process

The present invention relates to a non-slip mat manufactured by using a pressurizing process, and more particularly, after reaching a set temperature, the rubber dough and the carpet are replaced with a pressurized pressure at a set pressure to increase productivity according to manufacturing. It can also increase the sharpness of the end of the projection to improve the non-slip property of the basic nonwoven fabric of the interior floor of various transportation vehicles, and at the same time, by forming an additional projection pattern at the end of the projection, the non-slip is double The present invention relates to a non-slip mat manufactured using a pressing process that can form a high quality mat by forming a pattern.

In general, a floor mat such as an interior floor of an automobile, a home, a ship, an aircraft, a train, a floor such as a entrance entrance or a corridor of a building, in particular a floor (hereinafter referred to as a "floor") on which a basic non-woven or carpet fabric is laid mat) is installed. Although the mat may be made of a single material, a cushion sheet such as a nonwoven fabric or a carpet is mainly used for the upper layer that is generally exposed to the outside, and a pad 114 that is attached to the bottom of the cushion sheet and contacts the bottom is mainly used. In order to prevent the mat from slipping on the floor, it is necessary to form a certain form of protrusions on the pad contacting the floor to provide proper friction resistance.

1 is a block diagram showing a conventional general mat as described above in cross section. Typically, the mat is a pad 114 formed of PVC or soft rubber dough 10, a carpet 11 having a myriad of formed cilia and attached to an upper surface of the pad 114, and the pad 114 and the carpet. It consists of the suture 12 attached around the edge of (11). At this time, the non-slip protrusion 114a is formed on the lower surface of the mat at tight intervals to prevent slipping with the indoor floor surface. The projections 114a are designed to be plastically deformed during molding of the mat without attaching them for the purpose of airborne reduction. According to the conventional process, the pad 114 is cut into a predetermined shape, surface treated with a thinner and primed, and then the carpet 11 cut into the predetermined shape is attached with an adhesive. Subsequently, after passing through a heating furnace of about 15cm, it is pressed with a press and finally cut the shape is completed with a suture (12). Therefore, when using the conventional method, there is a disadvantage that a loss of material is large as a facility such as a heating furnace is required and cutting after pressure molding. In addition, in the conventional case, since the mat product to be produced has only a primary projection pattern, there is a problem in that high-quality products cannot be made because non-slip efficiency is lowered.

Therefore, an object of the present invention is to solve the above problems, and after reaching the set temperature, the rubber dough and the carpet is replaced by pressing at a set pressure and molded in one step to increase the productivity according to manufacturing and also various transportation vehicles In order to improve the non-slipness of the basic non-woven fabric of the floor, such as the interior floor of the building, the entrance of the building entrance or hallway, etc., the sharpness of the end of the protrusion is increased and an additional protrusion pattern is formed at the end of the protrusion. It is to provide a non-slip mat manufactured by using a pressing process that can make a high quality mat by forming a non-slip pattern double.
