Description

Releasing material, manufacturing method of the same and road molding method of using the same

The present invention relates to a release agent composition, a method for producing the same, and a road molding method using the same, and more particularly, to a liquid type release agent composition, a method for preparing the same, and a road surface forming method using the same, which compensates for the disadvantages of the conventional powder type release agent.

Exposed concrete, including colored patterned concrete constructed by wet and dry methods, typically uses a molding mold for aesthetic relief molding. In general, such a relief molding process uses newly prepared concrete or mortar by using hydrophobic fine particles by applying stearic fatty acid coating to powder type paraffin or fine powder having color in order to obtain the three-dimensional appearance, color expression and release effect of the relief. After the slurry was laid, a release film was formed on the uncured plastering surface, and the target surface was molded using a desired relief mold mat.

Many problems have been pointed out for the powder type in the composition of the release film used for molding and color expression. Conventional prior art method has a problem due to the scattering dust in the use of powder type release film and the release agent discharged in the washing process for removal of the release film for the effect of the shadow of the concrete relief, there is almost no corrosion because of strong chemical resistance, namely If it is buried in the soil or discarded in a river or the like, it does not decay at all, and thus, it has become a major cause of very serious environmental pollution, which contaminates soil and water quality and damages the natural environment.

In today's world, research on natural biodegradable products is being actively conducted, and efforts to alleviate problems caused by the disposal of secondary by-products are being actively conducted in various fields, but they can be decomposed without environmental pollution in a natural state. The groundbreaking development of the product has not been achieved. On the other hand, the scope of applying exposed concrete, including wet-drying and colored-patterned concrete, serves as a collective site where a large number of the public communicate with the mobile passage. In recent years, it is urgent that measures to prevent the infectious environment to control the spread of infection paths through livestock, animals, and the like.

The batch process of exposed concrete and asphalt, including wet-drying method of color-patterned concrete limited to the prior art, prepares concrete or asphalt with a certain compounding strength on a designated road surface, and then subjects the surface to a standard level, and then Before the end of the asphalt, the gray surface concrete is overlaid with a hardener of the desired color, and the surface is re-polished to cause the supernatant. The overlay coat is then completed by spraying and plastering the premixed dry mortar or slurry for the overlay coat. The overlay coat process is followed by applying a release film intended for the release effect and the shade effect of the secondary color on the concrete or asphalt using a powder type release agent.

Continuously, the molding is completed by using a stamp mat, which is a relief molding tool, and the final sealing is cured through a process of removing the release film of the powder type secondary color by washing with water to express the primary color. Finally, the batch process is finished.

Therefore, the problem of using the powder type release agent as a release film in the batch process of the conventional method described above, and the invention of an environmentally friendly release agent is an urgent situation.

To summarize the shortcomings of the prior art, firstly, the release agent scattering in the process of spraying the powder type release agent on the unconsolidated concrete may contaminate the atmospheric environment, and second, the powder is washed with water to express the desired primary color concrete. The type of release agent can be removed to contaminate the ecosystem of rivers and the ground, and thirdly, since it is installed in a plurality of mobile passages, there is a fear that it will be spread as a carrier medium for breeding germs at the bottom of an exchange group.

Furthermore, conventional antimicrobials could exhibit antimicrobial activity by addition of silver antimicrobial compounds to water-based and oil-based polymer resins or any organic material known to those skilled in the art. However, for example, silver salts can be washed out of the coating material very rapidly under carrier conditions, or the oxidation of metals by the surrounding environment is easily performed. Therefore, these silver antimicrobial systems exhibit short-term effects rather than long-term durability. Could be

- vegetable oil

The vegetable oil is characterized in that it comprises 65.8 ~ 80.0 parts by weight of the main oil and 1.0 ~ 10.0 parts by weight of the auxiliary oil, the auxiliary oil may be soybean oil, the main oil may be canola oil. .

Further, the vegetable oil may include canola oil, palm oil, olive oil, corn oil, cottonseed oil, sunflower oil, sunflower oil, castor oil, soybean oil, castor oil, coconut oil, coconut oil, Flaxed oil (linseed oil) is characterized in that any one or a mixture of two or more.

An object of the present invention is to produce a vegetable mold release oil having a high moldability, mold release properties and a low pour point by blending and chemical reaction of vegetable oil that can be used as a release oil to provide an environment-friendly color release concrete mat release agent for the process .

The vegetable oil of the present invention is preferably a mixture of rapeseed oil and soybean oil. The reason is that in case of using only rapeseed oil, there is a problem in that the releasing oil flows to the relief bottom dead center in wettability that is all of the interface of the concrete relief shape due to the characteristics of the colored concrete mat method, and the distribution ratio of the top dead center release oil of the concrete relief shape in the flow is Not only is there a problem that the irregularity is significantly lowered, but there is also a problem in lubricity, so that the soybean oil is mixed to improve the pour point and the mutual stability with the concrete, and has the advantage of reducing the change in viscosity due to temperature changes.

As a release agent for the colored pattern concrete mat method of the present invention, it is preferable to use a material in which the soybean oil and the canola oil are blended in a ratio of 5 to 30: 60 to 90, without using petroleum mineral oil.

By properly blending the rapeseed oil and soybean oil, a very stable releasing oil mixture is achieved, while at the same time the polarity and viscosity of the rapeseed oil and soybean oil are very good by utilizing excellent viscosity / infiltration changes in the absence or increase in temperature over a wide temperature range. It acts as an oil that is well sprayed and forms a temporary release film on the concrete surface. Another reason for mixing rapeseed oil and soybean oil is that when the rapeseed oil is to be used alone, the releasing oil flows from the relief cross section to the bottom of the concrete relief bottom when forming concrete in the wettability which is the interface of the concrete relief shape. There is a problem, and there is a problem that the distribution ratio of the releasing oil is significantly lowered in the cross section of the relief when molding the concrete in the flow, and there is also a problem in the lubricity of the mold. The mutual stability of the and the mold is ensured and there is an advantage to reduce the change in viscosity with temperature changes.

In this case, when the content of soybean oil is 30% by weight or more, crystals are formed at low temperatures and solidification occurs at high temperatures, resulting in an increase in the pour point, which causes problems in winter use, and conditions for addition of a pour point regulator to control the pour point. Causes problems leading to lower biodegradability. In the case of using 5 parts by weight or less, the mixing ratio of mixed vegetable oil is preferably 5.0 parts by weight to 30.0 parts by weight of soybean oil and 65.0 parts by weight to 85.0 parts by weight of soybean oil, since the wettability of the release oil is not improved.

The rapeseed oil (Canola Oil) is an oil extracted from rapeseed (Rape seed) as a representative material of vegetable fats and oils obtained by extracting from natural plants having excellent moisturizing function and increasing the efficacy of the release, similar vegetable fats and oils canola oil (Canola Oil) ), Palm oil, olive oil, corn oil, cottonseed oil, sunflower oil, castor oil, soybean oil, castor oil, coconut oil, linseed oil, etc. Can be used alone or in combination of two or more types. If the vegetable oil is used in more than 90% by weight, it is difficult to dissolve other additives, there is a concern such as precipitation during storage, when using less than 45% by weight it is difficult to obtain the desired release properties and there is a disadvantage that is not economical.

-Antibacterial agents

The antimicrobial agent is Ag-Cu-CyD (Zn-polymer), wherein the CyD (cyclodextrin) derivative is α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin, sulfoalkylβ-cyclodextrin, and hydride. Hydroxypropylβ-cyclodextrin (HPCD), hydroxyethylβ-cyclodextrin, 2-hydroxypropylβ-cyclodextrin, etherβ-cyclodextrin, methylβ-cyclodextrin, dimethylβ-cyclodextrin, trimethylβ-cyclo And at least one selected from dextrin, glucosylβ-cyclodextrin, maltosylβ-cyclodextrin, ethylβ-cyclodextrin, and sulfobutyletherβ-cyclodextrin.

In the present invention, the antimicrobial agent comprises a binder polymer and zinc (ZnO) nanoparticles in a core in which alloy nanoparticles composed of silver (Ag) and copper (Cu) are enclosed in a cavity in a cyclodextrin (CyD). Shell layer is coated Ag-Cu-CyD (Zn-polymer) antimicrobial agent.

Ag-Cu-CyD (Zn-polymer) antimicrobial agent in the present invention is for road paving or flooring, it is made of spherical or polygonal particles consisting of a core-shell composite structure.

Ag-Cu-CyD (Zn-polymer) antimicrobial particles in the present invention is excellent in stability that the particle size of 1 ~ 300nm or less. If the particle diameter is larger than 300 nm, a phenomenon of spontaneous sedimentation due to its own weight occurs. If the particle size is less than 1 nm, the active antibacterial effect is reduced.

When the alloy nanoparticles and the metal nanoparticles themselves have an antimicrobial activity in the form of powders or colloids, the nanoparticles are aggregated or aggregated, resulting in uneven and weakened antimicrobial activity. This is because the amount of elution of antibacterial ions decreases.

However, since the Ag-Cu-CyD (Zn-polymer) antimicrobial agent according to the present invention is composed of the core-shell composite structure as described above, the antimicrobial nanoparticles are uniformly dispersed within the antimicrobial agent particle structure as well as preventing the aggregation between the antimicrobial agent particles so as to have a uniform particle spacing. Since it can be present as a sufficient amount of antibacterial activity can be obtained.

 In the Ag-Cu-CyD (Zn-polymer) antimicrobial agent according to the present invention, copper and silver of the core are the first active antimicrobial alloy, and zinc of the shell is the second active antibacterial metal to increase the antimicrobial ion dissolution output under various conditions, Contributes to strengthening the antimicrobial and antimicrobial properties of antimicrobial agents. The cyclodextrin of the core and the binder polymer of the shell act as a double protective film to perform the interaction to enhance the durability and stability of the antimicrobial agent, thereby improving the life of the antimicrobial agent is stored in powder or colloidal form. This is because even if the cyclodextrin is insufficient to stabilize the silver-copper alloy nanoparticles, the binder polymer can reinforce the stability. These Ag-Cu-CyD (Zn-polymer) antimicrobials have a high enough stability for use as commercially available products that are stable under various storage conditions.

The core is composed of a structure in which silver-copper alloy nanoparticles having an antimicrobial ability are eluted to be contained in a pupil of a cyclodextrin (CyD), which is a derivative. That is, the silver-copper alloy nanoparticles can be seen as a 'core in the core', the cyclodextrin can be seen as a 'shell in the core', Ag-Cu-CyD (Zn-polymer) antimicrobial agent according to the present invention Can be said to consist of a double protective film structure as a whole.

Cyclodextrin (CyD) and silver-copper alloy nanoparticles in the core may be composed of 1: 0.5 to 2 mol (mol) ratio. If the number of moles of silver-copper alloy nanoparticles to the number of moles of cyclonedextrin (CyD) is less than 50%, there is a problem of lowering the critical inclusion rate and deteriorating active antibacterial performance. Not only the antimicrobial activity is significantly reduced, but mechanical properties may decrease.

 The shell (shell) is a shell coating the core, the binder polymer is applied as a binder of the concrete instead of cement in the resin concrete, and the use of plating on the reinforcing steel to prevent cracking of the reinforcement corrosion and concrete of the metal having antibacterial activity It is composed of zinc (Zn), which is also used as a material, and serves to stabilize the core from corrosion, dissolution, decomposition, and expansion with antibacterial action.

In the present invention, the Ag-Cu-CyD (Zn-polymer) antimicrobial agent may be blended in concrete as a binder or added as a functional admixture. In either case, the binder polymer, which is the mold agent of the shell, contributes to strengthening the fastness and durability of the concrete. The effect on this can be inferred from Patent No. 0967654 (the superhard concrete composition containing the core cell polymerization acrylic polymer).

-Color indicator

Color indicators or dyes may be added to the release agents of the present invention. The function of the color indicator is to show the proper formulation of the release agent to the concrete surface when it is necessary or beneficial to visualize the development of secondary colors on the concrete or asphalt surface.

In general, the color indicator chosen is stable in oil-based media and is chemically compatible with the other ingredients in the release agent. On the other hand, in the release agent composition of the present invention, a commercially available fat-soluble dye can be used for enhancing the coloring effect and for the expression of a suitable secondary color.

The dye as a color indicator is dissolved in the form of metal complex dyes, azo metal complex salts and phthalocyanine dyes with organic solvents methanol, ethanol, alcohols, ketones, esters, glycols, ethers and binders. Can be used.

The color indicator used in this example is selected as Fantha Colors® (MF-Series) as a dye having excellent transparency and vivid color and no bleeding phenomenon, and the addition amount is based on the total weight of the release agent composition for the colored concrete mat method. 0.01-0.8 weight part, Preferably it mix | blends in the quantity of 0.1-0.5 weight%. When the amount of dye, the color indicator used, is less than 0.01% by weight, it is difficult to expect the expression of color, and when 0.5 parts by weight or more is used, the primary color of the premixed dry mortar or slurry for the overlay coat is turbid. Difficult to expect

-Emulsifiers

Preferred emulsifiers for use in the present invention are nonionic surfactants that optimize the antibacterial performance of Ag-Cu-CyD (Zn-polymer) and the releasability of plant oils.

The nonionic surfactant is an ethoxylate such as lauryl alcohol, oleyl alcohol, laurylamine, ethoxylate of oleylamine, Pluronic P123, P103, P85, P68, F68, F127, F98, It is selected from the amine salt of oleic acid and a sulfonate salt, and can use any.

In the examples of the present invention, it is selected as an exemplary Pluronic P68-BASF used for antimicrobial inclusions with heterogeneity of solution. For example, a typical block copolymer of a nonionic surfactant compound that is compatible with most Ag-Cu-CyD (Zn-polymer) may use a polyoxypropylene-polyoxyethylene block copolymer (Pluronic P68-BASF). The addition amount is 0.01 to 0.5% by weight, preferably in an amount of 0.05 to 0.3% by weight. If the amount is less than 0.01% by weight, it is difficult to dissolve other additives, so it is difficult to expect a stable releasability. If the amount is 0.3% by weight or more, the film phenomenon may be inhibited or foaming may occur.

-Plasticizer

The plasticizer used in the present invention is used to help dissolve or increase the solubility of the binder polyvinyl alcohol and polyvinylpyrrolidone, and can be plasticized and for the purpose of making its flexibility permanent. It is prepared by dissolving in a solvent.

Examples of plasticizers used in release polymer compositions for colored concrete mat processes include alkanediol, 1,3-propanediol, 1,6-hexanediol, triol, diglycol, triglycol, DMSO, polyethyleneglycol, and Polypropylene glycol, urea, glycerin, neopentyl glycol, polyol, ether, ethylene glycol, polyglycol, propylene glycol, triethanol glycol, sorbitol, xylitol and mixtures thereof can be selected and used.

The plasticizer applied to the binder used in this example is selected from glycerin. The amount of plasticizer added in the above is preferably 0.05 to 1.5% by weight relative to the weight of the binder.

When the amount of plasticizer added is less than 0.05% by weight, the binder material has insufficient solidification of the forming oil film forming the encapsulation of the Ag-Cu-CyD (Zn-polymer) antimicrobial agent, while the colored concrete mat when the amount added is 1.5% by weight or more. The release polymer compositions for the process adhere to each other, making it impossible to carry out a process to obtain the desired thickness for concentrating the antimicrobial inclusion compound in the concrete.

In addition, silicone oils used as release aids as auxiliary lubricity enhancers include polydimethylsiloxane oils, polymethylsiloxane oils, and cyclomethicone oils alone or mixed. Can be used.

The antifoaming agent used in this embodiment is selected from volatile and non-reactive polymethylsiloxane, and the amount of the antifoaming agent is 0.5 to 8.0% by weight, preferably 1.0 to 6.0% by weight, based on the total weight of the release agent composition for the colored concrete mat method. Blend.
