Abstract

[Technical field to which the invention described in the claims belong]

It is not slippery when worn, and it is used as a finishing material on stairs, ramps, or floors of corridors of multi-use facilities (subway, viaducts, underpasses, public buildings, schools) to prevent the passengers from slipping and getting injured. Artificial stone easy to quench.

[Technical Challenges to Invent]

When worn down, the surface does not become smooth and the surface with high friction coefficient is continuous so that passersby does not slip and contaminants do not penetrate inside, so it is not dirty and easy to clean. Manufacture of artificial stone with an internal structure that can be prevented.

[Summary of the solution of the invention]

It is designed to prevent slippage by maintaining a large coefficient of friction even if wear progresses by filling soft and highly elastic materials in the pores of artificial or natural stones with a high coefficient of friction due to the tightness of grains and gaps between grains like artificial abrasive stones. .

If you put a knife or sickle on the artificial abrasive stone, the pores are filled with worn materials, and the foreign matters filled with the pores are washed with tying water, which is difficult to grind. Filled and hardened to prevent a decrease in the coefficient of friction.

[Important Uses of the Invention]

Non-slip floor finishes where passengers may be slipped and injured, such as stairways, ramps, or passages in underground passages in facilities used by multiple people (underground, overpasses, underpasses, public buildings, schools).

Non-slip floor finishes used in wet and slippery areas such as bathrooms and swimming pools.

It is a substitute for sidewalk blocks (interlocking blocks, etc.), which have a lot of voids and get dirty with contaminants such as dust and moisture.

Description

Non-slip artificial stone that is easy to clean because it is not slippery even if worn out and foreign substances do not penetrate

The present invention relates to the invention of artificial stone that the floor finish of the staircase or ramp is slippery to prevent the passenger from falling over and being injured.

Stairs and ramps of facilities used by multiple people (subway, overpass, underground public building, school) are often slippery due to slippery floors.

In order to prevent this, the surface of the stone used as a finishing material (stepping or roasting) is used on the floor of stairs or ramps, but it is a problem that it wears and slips after many years.

Another problem is that if the surface is roughened, cleaning is difficult.

In addition, there is a case of attaching a non-slip tape (one made of sandpaper with a 50mm dock) or a non-slip material (stair non-slip) made of metal, which has a problem of short life or difficulty in installing in stone.

It is worth trying to use materials with many voids (such as artificial abrasives, concrete blocks, and interlocking blocks, which are a type of concrete brick sidewalk blocks), which will increase the frictional force due to the large surface irregularities.

However, this method has a problem of cleaning and aesthetics because foreign matters such as dust and moisture accumulate and harden in the air gap for a long time, and the surface becomes smooth and friction coefficient is remarkably dropped. .

When worn down, the surface is not slippery and the surface with large coefficient of friction is continuous so that the passerby does not slip, and the pedestrians do not penetrate inside, so it does not become discolored and is easy to clean. To avoid injury.

The non-slip artificial stone consists of a friction material (particles such as silica, alumina, silicon nitride, silicon carbide, etc.) and a friction material (bonding cement, etc. when baking cement cement). It is composed of a filler that fills the and when manufactured in a way that the friction material itself has a bonding force, a separate binder can be omitted, and if color control is required, the pigment will be added.

The gist of the present invention is that the finishing material of stairs or ramps lacks the coefficient of friction, so as to prevent the passengers from slipping, there are many voids and fine irregularities on the surface, such as conventional artificial polished stones, so that the rubber or silicone The idea is to create a non-slip artificial stone filled with a soft and elastic material, such as King, and use it as a finishing material.

Filling the voids with a soft and elastic material filler prevents the ingress of dust and water, hardens the dust and moisture penetrating into the pores, smoothes the surface and prevents slipping. Wedges can also be prevented.

When a person's shoes touch the surface of the artificial stone, the filler, a soft and elastic material filled in the voids, contracts slightly under pressure due to the weight of the human body, but the friction material, which is a grain of artificial stone, is firmly bonded to each other with a binder. If not, only the pellets will protrude slightly and the coefficient of friction will be large and not slippery.

If the binder is harder than the friction material and the artificial stone is made to fill the voids, the strength and abrasion resistance will be excellent, but the surface will be evenly worn and slippery and the friction material will not protrude on the surface even under pressure.

If the low hardness and elastic binder is used to make no voids, the binder on the surface will wear out at a certain height before the friction material, so that the friction material can protrude and maintain the roughness. This will cause the entire artificial stone to shrink and stretch due to temperature changes, which will be a problem.

If you use adhesive bond with strong bonding force and there are many voids, it is difficult to remove the abrasive and due to the fine irregularities on the surface, it is possible to prevent slippage due to the large coefficient of friction. Spills of contaminating liquids, such as coffee or coffee, will be contaminated, hurting aesthetics and difficult to clean.

Filling the voids in the filling method is a method such as indentation and dipping. For example, if particles of high hardness, such as silicon carbide, which are touched at a high temperature of pottery, are mixed with clay, which is a raw material for tiles, beads of 1 to 3 mm in diameter are made, and the beads are brought into contact with each other to form a bottom plate or stepped shape. Beaded irregularities will also prevent slipping while preventing slipping due to friction of particles.

If the same size beads are used, 30 ~ 50% of voids are formed, which may be filled with contaminants such as dust and water, which may damage the beauty or reduce the irregularities of the beads. The surface of the resin will always be exposed and the interior and resin will be protected by the beads so that they will always remain filled without being worn beyond a certain depth.

In this case, the binder is clay, the particles or beads are friction material, and the filler is synthetic resin.

Stairs or ramps. Using this artificial stone as a floor finishing material in the aisle like a subway station floor, no matter how worn it will be, the passerby will not slip and get injured, and the cleaning will be easy without any difference from the general stone finishing material that smoothed the surface. It can be prevented from penetrating and soiling and damaging the beauty. You can also use the same effect on a wet place, such as a bathroom or swimming pool, where it is slippery and requires frequent cleaning.
