Description

Ultra-fast curing surface coating agent and colored asphalt {ommited}

The present invention relates to a surface coating agent for color asphalt.

As the surface coating agent of the known color asphalt, the registration number 20-0364311-0000

The content of the surface coating agent for color asphalt maintenance and repair, which is prepared by dissolving synthetic resin in water (H 2 O), which is an aqueous solvent, and additionally adding a pigment as necessary, is known.

But in the above,

As water (H20) is used as a solvent according to the solute,

Due to the weakening of water resistance, the strength of adhesiveness, abrasion resistance, pollution resistance, weather resistance, etc. is lowered,

In particular, the water (H 2 O) used as a solvent has a high boiling point due to the disadvantages of fast drying properties.

Therefore, in the present invention, in order to provide a good quality surface coating agent for color asphalt overcoming the disadvantages of the above-described inorganic solvent,

To various synthetic resins or elastomers, alone or in combination

Organic solvent MC (Methylene Chloride) or 141b alone or

To further prepare a surface coating agent for a transparent or colored asphalt with improved workability and workability by further mixing the solvent or other solvents having higher chemical properties such as boiling point than MC and 141b to the solvent alone or mixed.

In addition, by adding one or more kinds of various physical admixtures and chemical admixtures as necessary, it is possible to produce a surface coating agent with improved physical properties.

The present invention

It is conceived for the purpose of reinforcing various disadvantages according to the organic solvent and the aqueous solvent,

To alleviate the disadvantages of odor, flammability, environmental hazard, human harmfulness, etc., which are disadvantages of solvents such as thinner, toluene, alcohol, MEK, petroleum solvent, etc.

By eliminating the disadvantages of water resistance, quick drying, strength, adhesiveness, which are disadvantages of water (H2O), which is an aqueous solvent,

In order to provide a surface coating agent that satisfies the properties of the color asphalt surface coating agent such as wear resistance, weather resistance, pollution resistance, water resistance, adhesiveness and quick-drying, which are excellent mechanical properties

One or more kinds of polymers or elastomers may be used alone or in combination.

It provides a surface coating agent for color asphalt prepared by dissolving in MC or 141b which is an oil solvent.

Hereinafter, the present invention will be described in detail.

In the present invention for the above,

To a variety of single or mixed synthetic polymers or elastomers

Methylene Chloride (MC) or 141b, a low-boiling ultra-high volatile organic solvent, can be used alone or in combination

Or a mixed solvent in which one or more other solvents having a relatively high boiling point compared to the above solvents is used.

Boiling point comparison table for each solvent

   Solvent   Rain point     MC     40 ℃    141b     40 ℃     Methanol     64.65 ℃     ethanol    78.32 ℃     Propanol    97.15 ℃     Water (H2O)    100 ℃     Ethylene glycol    197.7 ℃     Etc      -

Besides

As a boiling point solvent, boiling point is 100-150 degreeC, toluene, xylene, butyl alcohol, etc.

High boiling point solvent It is possible to add at least one of the high boiling point solvents containing boiling point 150 ℃ or more butyl cellosolve, butyl cellosolve acetate, pe glycol, etc.,

In addition to the examples described above, various solvents may be included and used as additional input solvents.

This is because MC and 141b according to the present invention have a very low boiling point.

As a result of the rapid volatilization of the surface coating agent on the surface of the colored asphalt, the rapid curing of the synthetic resin polymer and the elastomer resulted in the application of the coating agent even though the coating was applied at very short time intervals (about 10 seconds). Since this leads to the disadvantage of not exhibiting smooth adhesion,

As exemplified in the above table, the surface coating agent is prepared by additionally mixing a relatively high boiling point volatile solvent, and as a result, the boiling point of the solvent is increased, thereby lowering the volatilization rate, thereby enabling smooth adhesion between the coatings sprayed with a certain time difference. The workability and workability are greatly improved.

In addition, the MC and 141b does not emit a bad odor compared to other organic solvents,

In particular, it has a nonflammable property with respect to flammability which is a disadvantage of the organic solvent,

It is a product that is not classified as an environmental risk organic solvent by environmental risk assessment, so it is a relatively safe organic solvent to the environment and human body.

On the other hand, by the addition of various physical admixtures and chemical admixtures described below at the time of the preparation of the surface coating agent it is possible to manufacture a surface coating agent for color asphalt more preferably improved.

  5) UV absorbers: substances that prevent color discoloration (prevention of weakening of the coating)

  6) Thickener: of prepared by adding additional aqueous solvent (emulsion, latex, etc.)

             Add to increase the apparent viscosity (methylcellulose, carbon black,

              Calcium carbonate and the like).

  7) Surfactant: Smoothly mixes and reacts with each raw material.

  8) Hardening agent: Especially when manufacturing surface coating agent using urethane raw materials

             In that case

             HMDI (hexamethylene di isocyanate) as a hardener,

             Yellowing resistance by adding IPDI (isoprone diisocyanate)

             It gives advantages such as weather resistance.

  9) Antioxidant: It is put in the adhesive which contains rubber as the main ingredient

              This is due to the fact that the rubber-based adhesive seals with sunlight.

               Or in order to prevent deterioration by oxygen or the like.

 10) Defoamer: It is used for the adhesive which a bubble is easy to remove, and

           It also prevents them from forming (silicone oil, etc.).

 11) Colorant: Used to give the adhesive the desired color as needed.

          (Dyes / pigments).
