Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing a decorative surface material for road surfaces, floors, and walls.

In particular, the unique colors of natural stones, artificial stones, and similar inorganic solids are utilized as they are after assimilation to enhance their decorative properties. By taking advantage of the voids created by the size of the particles and forming a surface with characteristics ranging from water permeable to water impermeable depending on the selection,
Manufacture of materials that can be used to decorate surfaces such as floors, walls, sidewalks and passageways, stairs, crossing overpasses, poolsides, etc. inside and outside of buildings to create beautiful, soft, water-permeable to non-water permeable surfaces. It is about the method.

[Prior art] Colored concrete, bricks, concrete stone slabs, tiles, various types of stone slabs, and hardened epoxy resin plates have been used as surface decorative materials for the above-mentioned floors, roads, stairs, etc., but none of them are very effective. Because it is hard and has no elasticity, it often cracks due to impact, and it often peels off or cracks due to expansion, expansion and contraction of the base. In addition, in cases where the base material is prone to sagging, such as on the iron plate of a crossing overpass or on an asphalt surface, these materials cannot follow the sway of the base and may crumble and peel.
I couldn't say it felt good when walking because it was hard.

In addition, when artificial pigments are used, such as in colored concrete, the finish is very artificial and unnatural, and the surface color may fade due to natural conditions or the effects of chemicals, and air permeability and water permeability are poor. Therefore, depending on the environment in which it is used, there are secondary problems such as mold and moss forming on the surface.

[Problems to be Solved by the Invention] The present invention provides high flexibility and sway, which could not be achieved with any conventional material, while at the same time reducing the particle size of the inorganic solid and the amount of resin used. By adjusting the combination, it is possible to form a surface layer with properties ranging from water permeable to water impermeable, and by using beautiful colored natural stones as inorganic solids, the unique natural color of the stone can be created. can be directly expressed on the surface as a finished color. Therefore, it is possible to produce decorative surface materials for roads, floors, and walls that are resistant to fading effects caused by natural conditions or chemicals.

[Means for solving the problem] Granular solids of natural stone, artificial stone, or similar inorganic solids with a diameter of 1 m to 20 m, and 7 to 15% of their weight.
urethane resin are uniformly stirred and mixed at a temperature of 5℃ to 40℃, and this mixture is poured directly onto road surfaces, floors, and walls to solidify, or poured into a mold for molding. To produce a surface decorative material for road surfaces, floors and walls, which has excellent deflection properties and water permeability or water impermeability, and is characterized by being solidified.

Depending on the combination of the particle size of the solid and the amount of resin used, surface decorative materials suitable for various uses can be obtained. The solid used should be thoroughly dried.

For example, when using a beautiful natural stone with a grain size of 1M to 20m, we first target the substrate with a particularly large sway, such as passages inside and outside buildings, floors, and crossing overpasses, to fade the color with low water permeability and a soft walking feel. When manufacturing a surface decorative material for forming a floor surface that takes advantage of the natural color unique to hard natural stone, a material with a small particle size of 1 m to 4 # is used.

In addition, when forming a floor surface with water permeability in a similar application, 5Mr is used to create voids and exhibit water permeability.
Use large grain sizes of 4 to 20 m.

The urethane resin is in a combination that causes a normal curing reaction, and is used in an amount such that each stone grain adheres to each other to form a solidified layer or solidified plate, that is, an amount of about 7 to 15% of the weight of the solid particles. . The mixing temperature of urethane resin and natural stone particles is between 5℃ and 4℃.
Perform at 0°C.

Examples will be described in more detail below.

[Example] After solidification with the surface decorative material of the present invention, the thickness is 10 m.

In order to manufacture the materials necessary for forming the surface layer of the passageway floor, it is necessary to use urethane resin 1.7 in a combination state that causes a normal curing reaction to dry natural stone 17 Nff with a particle size of 3 to 4 m.
NN is added and the mixture is stirred and mixed under a temperature condition of 5°C to 40°C so that the natural stone particles and urethane resin are sufficiently mixed. As a result, the surface of the natural stone is completely covered with resin.

Spread this mixture directly on the surface of cement N concrete flooring, asphalt concrete flooring, iron plate flooring, etc. that will be the base of the passage, and level the surface by pressing down the unevenness with a metal gouge etc. Finish it. The stone grains are bonded to each other by urethane resin, and when the urethane resin solidifies under a temperature condition of 5°C to 40°C, a 10 m thick decorative layer can be formed on the surface.

Comparative values of the deflection properties of the surface decorative material according to this example and the deflection properties of the surface decorative material made of the No. 1 oxyresin were measured by a pottery method test and are shown below.

Size of deflection (measured actual number of each 3 specimens) Unit (#) [Effects of the Invention] The surface decorative material of the present invention is finished with a surface that takes advantage of the unique color tone of the natural stone used.

Due to the characteristics of the urethane resin used in the process, it shows much higher deflection characteristics than epoxy resins, which are commonly used among conventional resins and are said to have relatively less deflection than bricks, tiles, etc. Therefore, even in the case of iron plate floors of crossing overpasses that are prone to sagging, and asphalt substrates, it follows the sagging of the substrate and does not crack or peel.In addition, the surface is highly flexible and has high impact resistance. It is possible to form a road or floor surface that has a soft walking feel without cracking even when hit by hard objects such as iron balls.

In addition, depending on the particle size of the natural stone grains used, it can be formed from water permeable to non-water permeable, so it can be used for a wide range of purposes, and the finished color takes advantage of the natural color unique to the stone grains, so it is suitable for natural conditions and It is less likely to fade due to the effects of chemicals, etc., and the natural color of the stone grains is maintained forever, resulting in a natural-looking finish.
