Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale and wherein like reference numerals in the various drawings refer to like elements.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flowchart showing a basic procedure for a method of manufacturing a high-adhesion, rubberized asphalt waterproofing material of the present invention.

1, the method for producing a high-adhesive-type rubberized asphalt waterproofing material of the present invention is characterized in that it comprises 46 to 71% by weight of asphalt, 5 to 18% by weight of rubber compounding oil, Preparing a base mixture by mixing 1 to 12% by weight of an asphalt modifier, 5 to 24% by weight of an asphalt modifier, and 11 to 36% by weight of a filler; heating the base mixture to 160 to 200 캜, To prepare a uniform compounding agent; And mixing the 90 to 95% by weight of the homogeneous compounding agent and 5 to 10% by weight of the synthetic rubber with a mechanical force mixer at a temperature of 160 to 200 DEG C to prepare a rubberized asphalt waterproofing material .

More specifically, the step of preparing the basic mixture includes a step of mixing 46 to 71% by weight of the asphalt, 5 to 18% by weight of the rubber compounding oil, 12 to 12 wt%, an asphalt modifier 5 to 24 wt%, and a filler 11 to 36 wt% are mixed to prepare a basic mixture for manufacturing an asphalt waterproofing material.

The asphalt is a petroleum-based asphalt, and it is preferable to use a general asphalt product which is solid at room temperature, which is not problematic for heating at 160 to 200 ° C.

The rubber compounded oil has a merit of good compatibility with natural rubber and synthetic rubber, good processability, good dispersibility as a compounding agent, and good affinity as a lubricant, so that uniform quality can be obtained at the time of molding, and resistance to moisture and aging And improves the physical properties of tensile strength, elasticity, extensibility, and abrasion resistance by imparting adhesiveness.

The tackifier may be any one selected from the group consisting of petroleum resin, rosin ester, rosin, and polybutene (PB), and the content thereof is limited to 1 to 12 wt%. In this case, when the tackifier is added in an amount exceeding the range, the viscosity of the product may be excessively felt and the workability may be deteriorated. If the tackifier is added in a very small amount, it may be difficult to maintain the tackiness.

In order to further improve the adhesive performance improving effect through the tackifier, 70 to 90% by weight of at least one of diethylene glycol and 2-hydroxypropyl ethylene glycol as rosin esters and α - 10 to 30% by weight of pine-ene as a tackifier. Ethyleneglycol abietate and 2-hydroxypropyleneglycol ethyleneglycol are excellent in tackiness among rosin esters and also have resistance to oxidation and aging, so they are suitable for use as an asphalt gel, and? -Pinene is a major component of pine rosin As a constituent component of the turpentine oil, it can serve as a solvent for the above-mentioned abietyl abietate and ethylene glycol 2-hydroxybutyric acid.

The asphalt modifier may be at least one selected from the group consisting of styrene-butadiene-styrene rubber (SBS), styrene-isoprene rubber (SIS) and polyisobutylene rubber (PIB) %. If the amount of the asphalt modifier is over the range, excessive viscosity may be excessively increased, resulting in deterioration of workability, excessive cost burden due to increase in unit price, and heat resistance It may not be able to fully demonstrate.

The filler may be any one selected from the group consisting of calcium carbonate, talc, slaked lime, clay, bentonite, and silica, and may be adjusted within the range of 11 to 36 wt% for viscosity control. There is a fear that the workability is lowered and the product is not dispersed smoothly, so that it may be difficult to uniformly mix the constituent materials.

After the basic mixture is prepared, the basic mixture is heated to 160 to 200 캜, followed by pulverization, melting and dispersion treatment to produce a uniform compounding agent. At this time, in the step of producing a homogeneous compounding agent, milling, melting and dispersing of the cutter are performed to reduce the size of the particles to increase the dispersibility and uniformly mix the materials, do.

After the step of producing the homogeneous compounding agent, 90 to 95% by weight of the homogeneous compounding agent and 5 to 10% by weight of the synthetic rubber are mixed and mixed in a mechanical forced mixer at a temperature of 160 to 200 DEG C to prepare a rubberized asphaltic waterproofing material Is performed.

At this time, the synthetic rubber to be mixed with the above-mentioned uniform compounding agent may be any one selected from the group consisting of butyl rubber (IIR), latex resin, regenerated latex and latex emulsion, It is preferable to use synthetic rubbers which can be easily softened and melted under the conditions, and it is also effective to further reduce the melting time by further refining the particle size.

The high-adhesive, rubberized asphalt waterproofing material produced by the above-mentioned method can be produced by modifying the asphalt in the same manner as above to produce a high-adhesion, flexible, gel state, thereby improving heat resistance, cold resistance, water tightness and adhesion performance. It is possible to provide a waterproof material capable of coping with the behavior and vibration of buildings and civil engineering structures.

In the above description, the filling material may be any one selected from the group consisting of calcium carbonate, talc, slaked lime, clay, bentonite, and silica. In order to increase the dispersibility, it is preferable that the particle size of the filler is made finer. Talc and silica are more suitable for particle refinement.

Therefore, in order to further satisfy the dispersibility in the material in addition to the viscosity control function through the filler, 30 to 70% by weight of the talc pulverized to a diameter of 0.1 to 50 μm and 30 to 70% by weight of colloidal silica having a diameter of 100 to 500 nm, May be used. This is a mixture of nano-colloidal silica and micro-milled talc, which contains many fine particles to increase the dispersibility in the material and satisfy the object of viscosity control.

In order to produce such a filler, a step of preparing the filler may be performed separately. The steps of preparing the filler including the crushed talc and the colloidal silica will be described in detail as follows.

Fig. 2 is a flow chart showing the step of preparing filler.

2, the step of preparing the filler comprises the steps of: pulverizing the talc to a diameter of 0.1 to 1 μm; adding sodium silicate to distilled water to prepare a silicate solution containing 3 to 10 wt% ; And 50 to 65% by weight of the silicate solution and 35 to 50% by weight of the cation exchange resin are mixed and stirred at a temperature of 20 to 40 ° C at 250 to 500 rpm for 3 to 10 minutes, Preparing a base solution comprising 1 to 10% by weight of silica by adding distilled water to the sodium silicate; And heating the base solution to 70 to 90 ° C, adding the silica sol at a rate of 6 to 7 times the weight of the base solution at 1 to 10 ml / min, maintaining the base solution for 4 to 8 hours to prepare colloidal silica And adding a polystyrenesulfonic acid resin to the colloidal silica to prepare colloidal silica from which residual sodium ions have been removed.

The step of pulverizing the talc to a diameter of 0.1 to 1 mu m is a step of pulverizing the talc particles into fine particles. Since there is no limitation in the pulverization method at this time, the talc is pulverized through the conventional method of crushing talc.

The step of preparing the silicate solution is a step of preparing a silicate solution for the production of active silica sol, wherein the silica weight range in the silicate solution is 3 to 10 wt% to facilitate the synthesis of the silica sol.

The silica sol is prepared by mixing 50 to 65% by weight of the silicate solution and 35 to 50% by weight of the cation exchange resin, stirring the mixture at a temperature of 20 to 40 ° C at 250 to 500 rpm for 3 to 10 minutes, Is in the range of 2 to 2.5, whereby the active agent of silica sol can be obtained simultaneously with the primary elimination of the sodium ions contained in the sodium silicate through the cation exchange resin.

The step of adding distilled water to sodium silicate to prepare a base solution containing 1 to 10% by weight of silica is a step of preparing a base solution for producing colloidal silica from the synthesized silica sol, wherein the silica weight range of the base solution Is 1 to 10% by weight, but it is more preferable to lower the weight ratio of silica to the above-mentioned silicate solution.

The step of preparing the colloidal silica may include heating the base solution to 70 to 90 ° C, adding the silica sol at a rate of 6 to 7 times the weight of the base solution at 1 to 10 ml / min, The colloidal silica is prepared by adding active silica sol to the base solution at a constant rate to obtain colloidal silica having excellent dispersion stability and hydrophilicity and having more uniform particle size.

The step of preparing the colloidal silica may include the step of adding polystyrene sulfonic acid resin to the colloidal silica to remove the residual sodium ions. When the sodium ion is remained, when the polymer is mixed with other materials of the waterproofing material, There is a possibility that the sodium ion may cause a chemical reaction to deteriorate the physical properties and waterproofing property. Therefore, colloidal silica in which residual sodium ions are removed is obtained through addition of a polystyrenesulfonic acid resin as a strongly acidic cation exchange resin.

The mixing of 30 to 70% by weight of the pulverized talc and 30 to 70% by weight of the colloidal silica is performed by mixing the pulverized talc and the colloidal silica prepared as described above in an appropriate weight ratio to prepare the filler of the present invention The process is performed. In this case, since the colloidal silica is dispersed in the aqueous solution, the pulverized talc is also dispersed in the aqueous solution, so that the colloidal silica and the talc can be uniformly dispersed, And no limitations are imposed.

The filler thus prepared is in the form of a dispersion in which colloidal silica and talc are dispersed in the aqueous solution. In the case of the filler, the filler is mixed with the other components in the production of the basic mixture and heated to 160 to 200 ° C for producing a uniform compounding agent. During the process, the water contained in the filler is dehydrated leaving only colloidal silica particles and crushed talc.

Therefore, through the thus prepared filler, not only the viscosity control effect through the pulverized talc but also the colloidal silica including the colloidal silica is improved and the colloidal silica is nano-sized, And thus the water-repellent property can be further increased because of the function of forming a dense film.

 Returning to the description of the waterproofing material, it has been described that the synthetic rubber, which is the material of the asphaltening waterproofing material of the present invention, can be any one selected from the group consisting of butyl rubber (IIR), latex resin, reclaimed latex and latex emulsion. In this case, the use of a latex emulsion is more effective in rapid softening and melting of a synthetic rubber, wherein either the latex or the regenerated latex is dispersed in an ethylene vinyl acetate (EVA) emulsion resin, and a chimney trophic index a latex emulsion having a thixototrophy index of 1.0 to 1.2 can be used.

This is a latex emulsion whose chisso trophy index is close to 1.0, and exhibits a low viscosity decreasing effect with increasing stirring speed. However, since the chewing gum trophic index tends to be lowered by heating, the problem can be canceled by assuming that the uniform compounding agent and the latex emulsion are mixed at a temperature of 160 to 200 ° C in the production of the waterproofing material of the present invention, It is needless to say that it is possible to compensate the fact that when the material has a high chisel trophy index even at room temperature, the physical properties as latex are poor. The process for producing such latex emulsion will be described as follows.

Figure 3 is a flow chart showing the steps for producing a latex emulsion.

Referring to FIG. 3, the step of preparing the latex emulsion comprises: preparing a ground latex by pulverizing bisphenol A type epoxy latex or bisphenol A type epoxy regenerated latex into 0.05 to 0.1 μm; Mixing 45 to 50% by weight of the pulverized latex with 45 to 50% of distilled water and 1 to 3% by weight of an emulsifier and then stirring at 500 to 1000 rpm for 3 to 5 minutes to prepare a latex dispersion; 40 to 70% by weight of an ethylene vinyl acetate (EVA) emulsion resin and 40 to 70% by weight of a latex dispersion are mixed and stirred at 1500 to 2500 rpm for 10 minutes to 15 minutes to prepare an emulsion mixture solution; Heating the emulsion mixture solution to 80 to 120 캜, and maintaining and stirring the emulsion mixture to obtain a latex emulsion having a moisture content of 10 to 25% adjusted in the emulsion mixture solution.

The step of preparing the pulverized latex is a step of pulverizing bisphenol A type epoxy latex or bisphenol A type epoxy regenerated latex to a particle size of 0.05 to 0.1 mu m to prepare a latex having a particle size suitable for emulsion production, In addition, bisphenol A type epoxy latex is preferably used for ease of emulsion production.

The latex dispersion is prepared by mixing 45 to 50% by weight of the pulverized latex with 45 to 50% of distilled water and 1 to 3% by weight of emulsifier and then stirring at 500 to 1000 rpm for 3 to 5 minutes to prepare a latex dispersion As a process, it is more effective to add an emulsifier in order to prepare a dispersion of bisphenol A type epoxy latex at this time, so that the efficiency of producing the dispersion is increased by adding 1 to 3% by weight of an emulsifier. At this time, there is no limitation on the kind of emulsifier.

The emulsion mixture is prepared by mixing 40 to 70% by weight of an ethylene vinyl acetate (EVA) emulsion resin and 40 to 70% by weight of a latex dispersion, and then stirring the mixture at 1500 to 2500 rpm for 10 minutes to 15 minutes to prepare an emulsion mixture In the case of the ethylene vinyl acetate emulsion resin, both the viscosity and the rubber elasticity are simultaneously exhibited, and the repeated bending strength and the impact strength are high. In addition, in the case of the ethylene vinyl acetate emulsion resin, since it is already emulsified, it has an advantage that it can be easily mixed with the above-mentioned latex dispersion.

The step of obtaining a latex emulsion is characterized in that the emulsion mixture is heated to 80 to 120 DEG C and then maintained and stirred to obtain a latex emulsion in which the moisture content in the emulsion mixture is adjusted to 10 to 25%, wherein the ethylene vinyl acetate emulsion resin and And the problem of bubbling that can occur due to excessive moisture contained in the waterproofing material by adjusting the water content contained in the latex dispersion.

Therefore, by mixing the synthetic rubber produced by the above-mentioned method with the above-mentioned uniform compounding agent, the viscosity and rubber elasticity of the waterproofing material can be further improved, and the properties of the adhesive force and the water resistance can be improved.
