Hereinafter, the non-slip coating composition according to the present invention will be described in detail.

The present invention provides a non-slip coating composition comprising a substrate of polyamide resin as a main component,

With respect to 100 parts by weight of the substrate, the polyamide resin is an acid modified polyamide resin,

120-140 parts by weight of waste aggregate powder for construction and 110-130 parts by weight of steelmaking slag powder,

When explaining the components of the non-slip coating agent composition according to the invention for each component in detail as follows.

In the present invention, the substrate uses an acid modified polyamide resin, and the acid-modified polyamide resin improves the binding force between components of the anti-slip coating composition, and has good heat resistance, mechanical strength and oil resistance. It improves the durability of the coated surface which is easily contaminated by soot, oil, etc., and is suitable for the base material of the coated surface composition.

The acid-modified polyamide resin used in the present invention is a thermoplastic aromatic polyamide resin, specifically, it is preferable that it is a terephthalic acid-modified polyamide resin, and the acid-modified polyamide resin used in the present invention is an alliance of Mitsui Chemicals, Japan. (ARLEN).

And in the present invention, by adding the powder pulverized waste resources such as construction waste aggregate and steelmaking slag to improve the performance of the slip resistance, wear resistance, durability, etc. of the coated surface.

The waste aggregate powder for construction is to improve the sliding resistance and abrasion resistance of the coated surface, it is preferable to use a pulverized to the size of about 1.5 ~ 2.0 mm.

The amount of construction waste aggregate powder added is preferably 120 to 140 parts by weight based on 100 parts by weight of the base material, and when the amount of construction waste aggregate powder is less than 120 parts by weight, performances such as slip resistance and wear resistance decrease. If the addition amount of construction waste aggregate powder exceeds 140 parts by weight, the mechanical properties of the pavement road due to the relatively insufficient amount of steelmaking slag powder or other additives due to the over addition of the construction waste aggregate powder There is a fear that the components of the anti-slip agent composition will lower or will not mix properly.

The steelmaking slag powder is a lightweight aggregate having excellent abrasion resistance to improve wear resistance of the coated surface, and it is preferable to use a pulverized powder having a size of about 1.5 to 2.0 mm.

It is preferable to add 110-130 weight part of steelmaking slag powder addition with respect to 100 weight part of base materials, and when the addition amount of steelmaking slag powder becomes less than 110 weight part, there exists a possibility that abrasion resistance performance of a coating surface may fall, steelmaking slag When the amount of the powder exceeds 130 parts by weight, the mechanical properties of the coated surface may be lowered due to the insufficient amount of the base or construction waste aggregate powder, etc., due to the over addition of the steelmaking slag powder.

And in the present invention, the filler is added to improve the durability and wear resistance of the coated surface.

It is preferable to add 50-60 weight part of addition amounts of the said filler with respect to 100 weight part of base materials. If the amount of the filler is less than 50 parts by weight, the durability and wear resistance of the non-slip coated surface may be lowered. If the amount of the filler is more than 60 parts by weight, the carbon additive or wax may be due to the excessive addition of the filler. Due to the insufficient amount of added, the components of the anti-slip agent composition may not be properly mixed or the mechanical properties of the pavement may decrease.

The filler usable in the present invention is preferably selected from one or more of silica, magnesium carbonate, talc, calcium carbonate, kaolin, mica.

The wax is then added to improve flowability during mixing of the anti-slip agent composition and during operation of the coated surface so that the components can be uniformly mixed.

It is preferable to add 15-20 weight part of addition amounts of the said wax with respect to 100 weight part of base materials. If the amount of the wax is less than 15 parts by weight, the components of the anti-slipper composition may not be uniformly mixed. If the amount of the wax is more than 20 parts by weight, the excessive amount of the wax may cause carbon fiber or glass. Components such as eggs may be separated or the performance of slip resistance after the coated surface may be degraded.

The wax usable in the present invention is preferably selected from one or more of polyethylene wax and polypropylene wax.

In the present invention, carbon fiber chop (carbon fiber chop) is a composite material of carbon fiber / phenol resin molded into a size of about 3-5 mm by mixing 65 to 75% by weight of carbon fiber and 25 to 35% by weight of the resol type phenolic resin As an ingredient, the components of the anti-slip agent composition are added to be firmly bound by the carbon fibers.

The carbon fiber chop is preferably added in an amount of 1 to 2 parts by weight based on 100 parts by weight of the substrate. If the amount of carbon fiber 첨가 is less than 1 part by weight, the bonding force between the components of the anti-slip agent composition is weakened, and the surface of the non-slip coating surface may easily crack due to the load or impact of a large truck. When the amount of the fiber 첨가 added exceeds 2 parts by weight, the coloring pigment or wax component may not be properly uniformly mixed due to the excessive addition of the carbon fiber 촙.

And glass bead (bead) in the present invention serves to prevent the traffic accident to easily identify the coated surface by emitting light in the danger zone that the driver should increase the sliding resistance at night.

It is preferable that the addition amount of the said glass bead adds 1-1.5 weight part with respect to 100 weight part of base materials. If the amount of glass eggs added is less than 1 part by weight, the amount of glass eggs added is small and there is a risk that the slippery packaging section may not be properly identified at night, and when the amount of glass eggs exceeds 1.5 parts by weight, the amount of glass eggs added There is a risk that the light of the headlights may be excessively reflected in the non-slip pavement section at night, which may obstruct the driver's vision.

And pigmented pigments can easily identify the surface of the non-slip paved road to increase the sliding resistance of the pavement in places where the slip resistance of the road surface is low for the safe driving of the car, or where the flatness and the longitudinal linearity of the road are poor. It is added to color the coating so that it can.

It is preferable that the addition amount of the said pigment pigment adds 1-1.5 weight part with respect to 100 weight part of base materials. If the amount of the coloring pigment is added below the range defined above, there is a concern that the anti-slip pavement may not show the color properly. If the amount of the coloring pigment exceeds the range defined above, the color of the non-slip pavement There is a fear that the color becomes too thick and obstructs the driver's view.

And it is preferable to add the coloring pigment within the range normally defined above, According to the color of a coloring pigment, you may adjust suitably and add it also out of the range defined above.

Therefore, the non-slip coating agent composition according to the present invention having the above components is stirred at a temperature of 230 ~ 250 ℃ at the site for the coating surface, evenly mixed and then coated surface construction, carbon fiber chop (carbon fiber chop) By strengthening the binding force between the components of the anti-slip coating agent, it is possible to suppress the crack of the coating surface due to the load and impact of a large vehicle as much as possible.
