Description

Hot melt type non-sleep coating material, method for producing thoreof and working method for road surface color coating}

 The present invention relates to a fusion-type non-slip coating material for road surface coating, a manufacturing method and a construction method thereof, and solves the problems of crack generation and road dropout, which are disadvantages of the conventional fusion-type coating and anti-slip material for road marking and landscape. Not only to make this beautiful, but also to maximize the sliding resistance to ensure the safety of vehicles, bicycle traffic and human walking, as well as high durability, crack resistance, crack resistance, adhesion, etc. To do it.

In general, in order to increase the visibility of the road and to prevent slipping, color asphalt, color concrete, fusion coating for road marking, anti-slip material and the like are used.

  However, the color ascon or color concrete should be paved with a thickness of 4 to 8 cm at the time of construction, so the construction cost is very high, and the surface of the aggregate is coated with a very thin colored coating of 50 to 100 μm. It is very difficult to preserve the color for a long time, and it is very difficult to preserve the color for a long time.In the case of the color ascon, due to the inherent adhesiveness of the color binder, foreign substances on the tires, shoes, etc. are transferred to the package and the surface is contaminated so that the color can be kept clean. There was no. In addition, due to these problems, there were problems such as maintenance costs consumed directly and indirectly, and waste of automobile fuel.

And conventionally used fusion coating agent is difficult to adhere to the road surface for a long time due to the weak adhesive force with the road surface, too low elasticity in order to have a suitable compressive strength tends to break easily at low temperature, so a large amount of cracks occur in winter, There was a problem in that the compressive strength corresponding to the increase in the traffic load due to the increase in the traffic volume was pressed and spread by the traffic load at a high temperature in summer.

In addition, the anti-slip material using the reactive material as a binder, the strength after curing is very strong but lacks the elasticity, and is weak against impact, and does not respond to shrinkage expansion according to the temperature of the road surface, poor adhesion to the road surface and cracks are generated , Due to the occurrence of cracks due to impact, etc. are detached from the road surface, and the coarse aggregate is used on the surface, so that the impact is relatively high and the dropping of the aggregate occurs, so the anti-slip effect is difficult to last for a long time. It is difficult to secure the driving stability, and the cost of repair and reconstruction due to frequent breakage and detachment, as well as the inconvenience of the driver caused by traffic control.

Therefore, the present invention has been made to solve all the problems of the conventional fusion coating or the non-slip coating material, the anti-skid coating of the road, the zone marking and anti-skid safety coating of the school zone, the color and slip of the bicycle road It is an object of the present invention to provide a fusion-resistant anti-slip coating material for road surface color coating, which is capable of preventing safety coating, inline skating landscape and safety coating, landscape and safety coating of trails and sidewalks, and a method of manufacturing and constructing the same.
In addition, when manufacturing the fusion-resistant non-slip coating material for road surface coating, by limiting the order of input of each component, uniform dispersion is performed to improve the physical properties of the product and to produce the product in a short time. There is a purpose.

In addition to the beautiful color coating as well as the beautiful scenery, it can maximize the sliding resistance to ensure the safety of vehicles, bicycles, and people walking, as well as high maintenance, heat resistance, crack resistance, adhesion, etc. To do it.

In addition, the present invention is excellent in physical properties there is almost no defects such as detachment, cracking, spreading after construction and the color is clear and advantageous to secure visibility of drivers and pedestrians, due to the aggregate contained in the coating and the color aggregate attached to the top It is to provide excellent slip resistance.

In order to achieve the above object, the method for producing a fusion-resistant slipper coating material for road surface color coating according to the present invention includes a resin for an adhesive binder, a viscosity modifier and an elastic modifier in a mixing tank, followed by stirring. And a first step of uniformly coating the surface of the elastic modifier and a dispersant and a pigment in a mixing tank in which the first step is completed, and stirring to uniformly disperse the surface of the viscosity modifier of the adhesive binder resin and the elastic modifier. And a third step of applying the aggregate and the inorganic filler to the mixing tank in which the second step is completed, and stirring the same so that the second step is uniformly dispersed. 5 minutes to 20 minutes after completion of the addition of the resin for the adhesive binder, the viscosity modifier and the elastic modifier, the second step is 10 minutes to 30 minutes, and the third step is 5 minutes Characterized in that 20 minutes.

In addition, the construction method is the step of applying a primer on the surface of the package,

Heat-melting the fusion non-slip coating material for road surface color coating at a melt tank at 160 to 190 ° C; applying the heat-melted coating material to a thickness of 1 to 2 mm with a fusion applicator; It characterized in that it comprises a step of spraying the color aggregate on the applied material.

The present invention provides an excellent anti-slip coating material for road surface color coating which exhibits excellent durability and adhesive force, shows excellent crack resistance at low temperatures, and secures excellent slip resistance and visibility due to surface spraying and adhesion of aggregates and glass beads. It is manufacturing and construction.

In addition, the existing color paving materials such as color ascon and color concrete have a very high construction cost due to the paving thickness of 4 to 8 cm, and are easily peeled off by driving or walking due to the very thin colored coating of 50 to 100 ㎛ on the aggregate surface. While it is very difficult to preserve the color for a long time, the present invention is constructed on the surface of the general road with a thickness of 1 to 2 mm and maintains color and slip resistance for a long time due to its unique durability, abrasion resistance and crack resistance. Not only is this inexpensive, but maintenance costs can also be greatly reduced.
In addition, when the fusion-type non-slip coating material for the road surface coating is limited, the order of input of each component is uniformly dispersed, thereby making it possible to produce a product in a short time because of excellent dispersion and easy dispersion. To maximize.

First, the fusion-resistant slipper coating material for the road surface color coating according to the present invention will be described. Fusion type anti-slip coating material for road surface color coating according to the present invention is 20 to 40% by weight resin for adhesive binder, 3 to 15% by weight viscosity modifier, 4 to 20% by weight elastic modifier, 20 to 40% by weight aggregate, inorganic filler It consists of 20-50 weight%, 1-10 weight% of dispersing agents, and 2-10 weight% of pigments.

The resin for the pressure-sensitive adhesive binder used in the present invention is a material that serves to improve the adhesive strength of the product and combines the respective constituent materials, the types thereof include C9 petroleum resin, C5 petroleum resin, C9-C5 copolymer petroleum resin, rosin, Rosin ester, coumarone resin, polybutene, etc. can be used individually or in mixture of 2 or more types. At this time, the resin for the adhesive binder is used as 20 to 40% by weight in the non-slip coating material, when the amount is less than 20% by weight of the adhesive binder is too small to play a role as a binder enough to the strength of the product and This is because the adhesive strength is lowered, and when the amount exceeds 40% by weight, the amount of use is so great that the adhesive strength is increased, but the modification effect by the elastic modifier is relatively low, so that the durability and crack resistance are weakened and the cost of the product is increased, thereby reducing the economic efficiency.

In addition, the viscosity modifier improves the construction performance by adjusting the viscosity of the product, and improves the adhesive performance, the kind of process oils, vegetable oils, synthetic oils and plasticizers, etc., the process oil is an aromatic , Naphthenic and paraffinic oils. Vegetable oils include linseed oil, soybean oil, lean seed oil, rice bran oil, etc., and synthetic oils and plasticizers include polyethylene glycols, polypropylene glycols, di-octyl phthalate (DOP), DBP (di-butyl phthalate) may be used alone or in combination of two or more. At this time, the viscosity modifier is used as 3 to 15% by weight in the non-slip coating material, if the amount is less than 3% by weight the amount is too small to perform the function of viscosity control enough to increase the viscosity of the product Due to the poor construction, there is a high risk of construction defects. If it exceeds 15% by weight, the amount of use is so high that the viscosity of the product is too low, making it difficult to secure sufficient thickness during construction, and the durability is also weakened. This is because the jungle cannot be prevented.

In addition, the elastic modifier is a material for improving the durability, heat resistance and crack resistance of the product, the type of polyethylene (PE), polypropylene (PP), ethyl vinyl acetate (EVA), APAO (Amorphous Poly- α-Olefine), APP (Atatic Polypropylene) or the like may be used alone or in combination of two or more thereof. At this time, the elastic modifier is used as 4 to 20% by weight in the non-slip coating material, if the amount is less than 4% by weight, the amount is too small, the modification effect is lowered, the durability and crack resistance of the product is weakened and the physical properties If the excellent product can not be obtained, if the amount exceeds 20% by weight, the amount of the modifier is more than necessary, the viscosity of the product rises, the construction is not easy, and the cost of the product also rises, it is impossible to produce an economical product.

The aggregate is used to improve the durability of the product and to strengthen the sliding resistance performance and to ensure visibility, the type of silica sand, sand, crushed sand, glass beads, cala silica, alumina aggregate, blast furnace slag aggregate, dolomite, etc. It can mix and use 2 or more types, The size of 0.1-2 mm of particle diameter can be used individually or in mixture of 2 or more types. The reason for limiting the particle size is that the particle size is less than 0.1mm is too small particles for the aggregate, so the effect of improving the physical properties such as compressive strength is almost the same as the inorganic filler, it is difficult to expect the efficacy as an aggregate, if it exceeds 2mm Since the size is larger than the construction thickness, it is more likely to be damaged or detached due to more external impact, which in turn adversely affects the durability of the product. At this time, the aggregate is used as 20 to 40% by weight in the non-slip coating material, if the amount is less than 20% by weight, the amount is too small to ensure sufficient slip resistance after the construction of the product, and also exhibits sufficient compressive strength of the product. It is not possible to prevent the crushing and crushing after construction, and if it exceeds 40% by weight, the amount of use is so large that the sliding resistance increases, but the compactness of the product is insufficient, and durability and crack resistance are weakened. This is because problems such as cracks may occur.

The inorganic filler is used to improve the compressive strength of the product and to reduce the manufacturing cost, the kind of calcium carbonate, talc, silica, mica, clay, fly ash, etc. may be used alone or in combination of two or more. . At this time, the inorganic filler is used as 20 to 50% by weight in the non-slip coating material, if the amount is less than 20% by weight the amount is too small to ensure sufficient compressive strength of the product is pressed after construction There are problems such as phenomena and jungle phenomena, and the reduction of product cost can not be expected greatly. If it exceeds 50% by weight, the adhesive strength of the product as a result of the relatively lack of other materials such as resin for adhesive binder and elastic modifier. This is because the cracking resistance is lowered, the viscosity is also high, the construction is not easy, and there may be problems such as product dropping and cracking after construction.

The dispersant serves to uniformly disperse the product constituent materials when the product is melted, the type of calcium stearate, zinc stearate, PE wax, PP wax, amide wax, etc. alone or in combination of two or more Can be used. At this time, the dispersant is used as 1 to 10% by weight in the non-slip coating material, if the amount is less than 1% by weight is too small to use the dispersion effect of the material can not be expected to ensure the uniform physical properties of the product If the amount of dispersant used is more than 10% by weight, the amount of the dispersant used is more than necessary, which increases the cost of the product and loses the price competitiveness.

In addition, the pigment is a material for expressing the color of the product, and may be used as appropriate for each color required, and the kind thereof is not limited. At this time, the pigment is used as 2 to 10% by weight in the non-slip coating material, if the amount is less than 2% by weight of the pigment is too small to obtain a vivid color product, if more than 10% by weight is more than necessary This is because the cost of the product will rise due to high usage, and thus the price competitiveness will be lost.

Fusion type anti-slip coating material for the road surface color coating of the present invention configured as described above can be applied to a thickness of 1 to 2mm on the surface of the road in general, and due to its unique durability, abrasion resistance, and crack resistance, color and slip resistance for a long time It can be maintained, and the construction cost is not only low, but also the maintenance cost is greatly reduced.

Hereinafter, a method for manufacturing a fusion-slip coating material for road surface color coating according to the present invention will be described. Since the amount and properties of each composition have been fully described above, a detailed description thereof will be described below.

The fusion-resistant anti-slip coating material for road surface color coating according to the present invention, as a first step, the resin for the adhesive binder, the viscosity modifier, the elastic modifier is added to the mixing tank and stirred so that the viscosity modifier is the surface of the resin for the adhesive binder and the elastic modifier. Ensure uniform coating on

 When the first step is completed, a dispersant is added to the mixing tank in which the first step is completed as a second step, followed by stirring to uniformly disperse and apply the coated surface of the viscosity modifier of the adhesive binder resin and the elastic modifier. At this time, in the second step, the pigment may be added and stirred together with the dispersant to uniformly disperse and apply the coated surface of the viscosity modifier of the adhesive binder resin and the elastic modifier.

When the second step is completed, the aggregate and the inorganic filler are added and stirred to the mixing tank in which the second step is completed to uniformly disperse the production of the anti-slip coating material.

As described above, the reason for manufacturing the fusion-type anti-slip coating material for road surface color coating according to the present invention in three steps is as follows.

First, the reason that the viscosity modifier is uniformly coated on the surface of the resin for the adhesive binder and the elastic modifier in the first step is that when the viscosity modifier is added in the second and third steps, the dispersion is not easy and partial dispersion may occur. This is because there may be a problem in that the physical properties of each packaged product are different after packaging.

In the second step, the dispersant and the pigment are added, because the pigment and the dispersant are very important to disperse the pigment and the dispersant so that the dispersion is easily performed during the kneading process by absorbing the viscosity control agent to maximize the effect To bet.

In addition, the reason why the inorganic filler and aggregate is added to the third step is that the amount of the inorganic filler and the aggregate is high, so that when the first to second stages are added, it is difficult to efficiently disperse the viscosity modifier, the pigment and the dispersant, and thus, the product of uniform physical properties is produced. This is because it is difficult to obtain.

In addition, the time required for each step from the first step to the third step is 5 minutes to 20 minutes after completion of the first step, 10 minutes to 30 minutes for the second step, and 5 minutes to 20 minutes for the third step. It is also possible to produce a product in a short time as described above to maximize the productivity of the product can also be said to be an advantage of the present invention.

For the convenience of the description of the present invention it was described as applying the primer and melting the non-slip coating material for the road surface color coating, but it may be carried out at the same time, it is natural that the melting step may proceed first.

When the melting is completed, it is applied to the surface of the primer-coated package with a thickness of 1 to 2 mm using a fusion applicator. In addition, immediately after the coating is sprayed with a color aggregate or a mixture of color aggregates and glass beads to adhere to the construction surface. That is, by spraying the color aggregate or a mixture of the color aggregate and the glass bead immediately after the application of the anti-slip coating material, it is possible to further secure the slip resistance and night visibility of the package.

As used herein, the color aggregate or a mixture of the color aggregate and the glass bead is one having a particle diameter of 0.1 to 2.0 mm, as used for the fusion-resistant anti-slip coating material for the road surface color coating, and the color is also the fusion-slip for road surface color coating. Use the same color as the color of the barrier coating.
