Description

An eco-friendly water-proof root-proof composition for artificial greening with adhesion, chemical resistance, flexibility, impact resistance, and penetration resistance, and construction method using the same}

The present invention relates to an eco-friendly waterproof anti-reflective composition for artificial greening having adhesiveness, chemical resistance, flexibility, impact resistance, and penetration resistance, and a construction method using the same.

Recently, artificial greening of building structures has been actively implemented in terms of urban ecological restoration and differentiation of buildings, and such artificial greening is suggested as a method to solve problems such as environmental pollution, ecosystem destruction, and climate change in cities that are occurring at present. have. In addition, it provides emotional effects such as mental and physical relaxation through energy saving for cooling and heating of buildings, flower cultivation, improved rooftop aesthetics, comfortable exercise and relaxation space formation.

In general, it consists of a waterproof layer, a dustproof layer, a drainage plate, a filter layer, a soil layer, and a planting layer. Among them, the waterproof layer and the dustproof layer are important considering long-term durability and economical maintenance costs.

The waterproof layer for artificial greening plays a role of blocking water, and the main required performance is to protect the waterproof layer from the penetration of plant roots, but it is subjected to mechanical shock and damage by greening equipment and repair equipment, and contains moisture. It is damaged by continuous long-term load from the penetration of plant roots that have strong growth power that penetrates even in very small crevices. In addition, if water always stays on the upper part of the waterproof layer and is placed in a humid environment, it causes water pollution due to deterioration of the waterproof layer and the elution of harmful substances from the surface. This occurs, and planting management such as chemical fertilizer and control is carried out, and it is easy to be subjected to chemical erosion by microorganisms and chemical substances. Therefore, the waterproof layer and the anti-vibration layer must have the same durability as the life of the building.

In the artificial greening system that is currently spreading in Korea, a waterproof layer is installed alone or a waterproofing barrier layer is installed alone. In addition, a method of separately installing the waterproof layer and the anti-dust layer is applied, and the material of the anti-dust layer is a sheet made of copper, roofing of polyethylene terephthalate (PET), polyethylene (PE) film, and fiber made of densely woven chemical fibers. Sheets and barrier sheets containing a root growth inhibitory chemical have been proposed. However, in the case of the anti-corrosion construction method using a sheet or film having anti-corrosion properties while forming the waterproof layer and the anti-corrosion layer, various anti-corrosion materials are applied to secure the required performance. Because it is determined, it is difficult to ensure a uniform rooting quality. Moreover, there is a problem that it cannot fundamentally solve the inefficiency of the manufacturing process due to the complexity of the production and the inefficiency of work due to the lamination construction in the field or the complex installation process. In other words, as shown in Fig. 1, heat-sealing of anti-vibration materials having joints, separation of tape treatment, lack of behavioral response to cracks on the ground surface, loss of function of anti-vibration sheets due to joints, damage during construction of landscape facilities. There is a problem in that there is a possibility of concern. In addition, Fig. 2 shows a method of constructing a conventional anti-vibration sheet, in which a joint is formed at the interface of the sheet during the lamination construction of the anti-vibration sheet 100 on the base surface 200. In this case, the gap of the joint is formed over time. Accordingly, there is a problem that the roots can be penetrated, resulting in a decrease in the rooting performance, and an integrated rooting layer cannot be formed.

On the other hand, polyurea is a polymer compound having a urea bond in its molecular structure, and is synthesized with diamines having a chain extension and a low molecular weight to form a urea unit. Therefore, polyurea not only has excellent water resistance, chemical resistance, etc., but also has superior abrasion resistance, heat resistance and stability than polyurethane, which is an additional carbon (C) and nitrogen atom (N) of the carbonyl group (C=O) present in the urea bond. ) Is due to the combination of Such polyurea appears after its properties vary widely depending on various factors such as a selected substance, molecular weight, and reacted ratio.

In addition, polyurea has excellent compressive strength, excellent acid resistance and alkali resistance, withstands UV rays well, and has low temperature dependence, so that it can be constructed even in winter. In particular, polyurea has the advantage of easy construction because it uses spray construction equipment, short construction period due to super-fast hardening, and can secure a coating film of a certain thickness. In other words, the polyurea waterproofing material is a technology for mixing and spraying polymer materials having excellent chemical resistance in a high-pressure collision method, and has the advantage of being easy to construct by using a spray mechanization equipment and securing a constant coating thickness even in the wall part.

Therefore, the present inventors pay attention to the technical requirements as described above, and provide excellent anti-corrosion performance to the polyurea waterproofing material with excellent physical properties, enabling rapid construction and forming an integrated waterproof anti-dust coating film of a certain thickness, and laminated in the field. The present invention was completed by developing an eco-friendly waterproof anti-fogging material composition for artificial greening that fundamentally solves the problem of non-uniformity in room resistance performance due to construction and inefficiency of work due to a complex installation process.

Advantages and features of the present invention, and a method of achieving them will become apparent with reference to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various forms different from each other, and only these embodiments make the disclosure of the present invention complete, and those of ordinary skill in the art to which the present invention pertains. It is provided to fully inform the person of the scope of the invention. In addition, terms used in the present specification are for explaining embodiments, and are not intended to limit the present invention. In the present specification, the singular form also includes the plural form unless otherwise specified in the phrase.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. On the other hand, the illustrations and detailed descriptions of configurations, actions and effects thereof that can be easily recognized by those of ordinary skill in the art will be simplified or omitted, and will be described in detail focusing on the parts related to the present invention.

The eco-friendly waterproof anti-foam composition for artificial greening having adhesiveness, chemical resistance, flexibility, impact resistance, and penetration resistance according to the present invention is a two-component polyurea coating composition containing a main material and a hardener, and the volume ratio of the main material and the curing agent is 1 It is characterized in that it is ~5:1.

The subject includes 35 to 60 parts by weight of a polyamine mixture, 20 to 30 parts by weight of a crosslinking agent, 5 to 10 parts by weight of a glass milled fiber, 5 to 10 parts by weight of a metallic ceramic pigment, and 6 to 9 parts by weight of an additive.

And the curing agent is obtained by reacting 60 to 80 parts by weight of an isocyanate mixture and 20 to 40 parts by weight of epoxidized hydroxyl-terminated polybutadiene (EHTPB) at 60 to 100° C. for 2 to 3 hours.

It will be described in detail the subject and the curing agent according to the present invention.

First, the polyamine mixture of the subject matter imparts excellent mechanical properties such as elongation for formation of a flexible coating film, impact resistance, crack resistance, and abrasion resistance, and the polyamine mixture of the present invention comprises 30 to 40 parts by weight of polyoxypropylene diamine and It is characterized in that formed by mixing 5 to 15 parts by weight of polyoxypropylene triamine. For example, the polyamine mixture in the present invention may be Huntsman's Jeffamine series (Jeffamine T-5000, Jeffamine D-2000, Jeffamine D-230, Jeffamine D-400, Jeffamine T-403).

The content of the polyamine mixture is preferably 35 to 60 parts by weight.If the content is less than 35 parts by weight, the effect on physical properties such as flexibility and impact resistance of the coating film is insignificant, and if it exceeds 60 parts by weight, the viscosity increases and is relatively different. There is a disadvantage in that it is difficult to make a polyurea coating composition having a desired physical property because the content of the composition is small. In addition, the weight average molecular weight of the polyamine mixture is preferably 200 to 5000.

In addition, the crosslinking agent affects the curing time of the paint and increases the degree of crosslinking to improve durability such as tensile strength, tear strength, and abrasion resistance, while improving reaction speed and improving weather resistance. In the present invention, the crosslinking agent may be an aromatic or aliphatic amine compound used as a chain extender. It is preferably composed of 10 to 15 parts by weight of an aromatic diamine and 10 to 15 parts by weight of an aliphatic diamine. For example, in the present invention, Palmerholland's Unilink4200 can be used as the aromatic diamine, and Palmerholland's Clearlink1000, Huntsman's Jefflink754, and Basf's Polyclear136 can be used as the aliphatic diamine.

The content of the crosslinking agent is preferably 20 to 30 parts by weight.If the content is less than 20 parts by weight, the effect of the chain extender is insignificant, so it is difficult to expect improvement of mechanical properties, and if it exceeds 30 parts by weight, excessive hardness improvement and elongation decrease. It is not desirable because it causes.

In addition, the glass milled fiber included in the subject matter is a powder-type filler obtained by pulverizing glass fiber into a powder form to form short fibers. It increases the tensile force to prevent cracking, and has good dispersibility and fluidity, so it is possible to impart surface smoothness. It becomes excellent. Therefore, when included in the waterproof anti-fogging material of the present invention, it is possible to improve the durability of the waterproof anti-reflective coating film to improve resistance to impact, and to reinforce chemical properties such as corrosion resistance and heat resistance. That is, due to the tensile force and impact resistance reinforced by the glass milled fiber, the waterproof anti-reflective material of the present invention can exhibit excellent penetration resistance, thereby forming a waterproof anti-reflective coating.

Preferably, the glass-milled fibers may have an average fiber length of 10 to 100 μm, and preferably, an average fiber length of 10 to 50 μm may be used. If the average fiber length of the glass milled fiber is less than 10㎛, problems such as workability may occur due to the increase in the viscosity of the product, and if it is more than 100㎛, the tensile performance and surface performance due to lack of bonding (density) after curing the product. This is because a problem may occur in smoothness.

In addition, the glass milled fiber is included in an amount of 5 to 10 parts by weight. If it is less than 5 parts by weight, the effect compared to the amount of glass milled fiber added is insignificant, and if it exceeds 10 parts by weight, the problem of increasing the viscosity of the product may occur, and the increase in physical properties is relatively insufficient.

In addition, metal-based ceramic pigments are pigments made by combining metal compounds at high temperature to give the color of polyurea paints, which improves heat resistance, chemical resistance, chemical resistance, and solvent resistance to form a chemically stable coating film. It is preferably any one selected from the group consisting of cobalt, zinc, nickel, titanium, aluminum, lithium, and mixtures thereof. For example, Hanil's P120 (Co-Al-Li pigment), P521 (Co-Al pigment), P600 (Co-Ni-Zn-Ti pigment), etc. can be used.

The content of the metallic ceramic pigment is preferably 5 to 10 parts by weight, and may be appropriately adjusted within the above-described range in order to form a chemically stable coating film and express a color of a desired concentration.

The additives may be mixed or used alone within the range of 6 to 9 parts by weight of an adhesion promoter, an antifoaming agent, a UV stabilizer, and the like, which are usually used in the composition of the paint.

The adhesion promoter serves to reinforce the adhesion to the substrate and the strength of the paint composition, and for example, an epoxy functional silane manufactured by Momentive may be used.

The antifoaming agent is added to prevent the occurrence of air bubbles, and can be used by selecting one or more of a mineral oil-based antifoaming agent, a silicone-based antifoaming agent, and a non-silicone-based polymeric antifoaming agent. For example, BYK's BYK-054 product, a non-silicone-based polymeric antifoaming agent, is used. Can be used.

The UV stabilizer prevents premature deterioration caused by UV rays, and for example, Tinuvin 328 manufactured by Ciba can be used.

The additive is added in consideration of the physical properties of the paint composition, reinforcing adhesion to the substrate, reinforcing the strength of the composition, suppressing air bubbles, and preventing premature deterioration, etc., but if it is less than 6 parts by weight, the effect is insignificant, and 9 parts by weight If it is exceeded, the effect is not significantly improved anymore and there is a concern that other physical properties of the composition may be deteriorated, which is not preferable.

In addition, the curing agent of the present invention is obtained by reacting 60 to 80 parts by weight of an isocyanate mixture and 20 to 40 parts by weight of epoxidized hydroxyl-terminated polybutadiene (EHTPB) at 60 to 100° C. for 2 to 3 hours.

At this time, the isocyanate mixture is methylene diphenyl diisocyanate (MDI), toluene diisocyanate (TDI), hexamethylene diisocyanate (HDI), hexamethylene diisocyanate trimer (HDT), iso It may be obtained by mixing at least one selected from the group consisting of poron diisocyanate (Isophorone Diisocyanate, IPDI) and cyclohexylmethane diisocyanate (Cyclohexylmethane Diisocyanate, H _{12 MDI).}

The epoxidized hydroxyl-terminated polybutadiene (EHTPB) improves adhesion to various substrates and improves water resistance, chemical resistance, flexibility and impact resistance. Specifically, the hydroxyl-terminated polybutadiene resin can form a 3D network-structured solid with an extended chain solvent and an interchain solvent at room temperature or high temperature, so it has excellent dynamic performance and resistance to hydrolysis, acid and lye, crushing, and low temperature. It is equipped with and shows electrical insulation. That is, in the present invention, by further including a polybutadiene resin at the end of the hydroxyl in the curing agent, a network is formed during the curing process to remarkably increase adhesion, while exhibiting excellent ductility due to butadiene groups, and imparting chemical resistance, heat resistance, and electrical insulation. do. By introducing an epoxy group to epoxidation, the polarity of the large molecule is increased, and the introduced epoxy group becomes a reactive functional group, thereby enhancing the mechanical properties, adhesive strength, and heat resistance of the polyurea after curing. Accordingly, the waterproof anti-reflective composition of the present invention can exhibit excellent adhesion to various ground surfaces, and improve water resistance, chemical resistance, flexibility and impact resistance. Preferably, the epoxidized hydroxyl-terminated polybutadiene resin may include at least one compound from among the compounds represented by the following Structural Formula 1 or Structural Formula 2.

More preferably, the epoxidized hydroxyl-terminated polybutadiene is represented by the following formula (1) and has a molecular weight of 100 to 10,000. For example, it may be an epoxidized hydroxyl-terminated polybutadiene having a molecular weight of 1,000 to 2,000.

<Formula 1>

However, the one or more epoxy-containing repeating units described above and the one or more olefin-based repeating units described above are present in the range of 1 to 20 of each repeating unit, and x may be in the range of 2 to 150.

The waterproof anti-corrosive composition of the present invention is a polyurea paint, which is a polyurea paint completed by mixing the main material and a curing agent, and the gelation time varies depending on the type and composition of the polymer, crosslinking agent, and curing agent in the main material. The form of is distinguished. Polyurea is a high-molecular material with elastomer properties. Because of the rapid reactivity of amines and isocyanates, polyurea cannot be mixed at room temperature in general, and paintwork is carried out using special spray equipment. In other words, it is characterized in that it passes through a mixing collision-type device without a mixing process using a two-component high-temperature, high-pressure spray device, and the two solutions are combined and cured within a few seconds or minutes after spraying to form a solid and thick coating film.

Therefore, as another aspect, the present invention is a pre-treatment step (S 10) of removing foreign substances from the ground surface; Including a step (S 20) of mixing and spraying the base material of the waterproofing repellent composition and the curing agent described above on the pretreated base surface (S 20); and, when mixing the base material and the curing agent of the waterproofing repellent composition, the liquid temperature is 50 to 80 It relates to a waterproofing method using an eco-friendly waterproofing waterproofing material composition for artificial greening, characterized in that the uniform waterproofing waterproofing coating film is formed by spraying and applying with a sprayer pressure of 1500~3000psi at ℃ and a sprayer pressure of 1500~3000psi.

3 is a conceptual diagram showing the anti-corrosion property of the waterproof anti-corrosive coating film formed of the waterproof anti-corrosive composition of the present invention. As described above, a polyurea waterproof anti-fogging material that provides excellent anti-corrosion performance and excellent physical properties to a polyurea waterproof material having excellent physical properties as described above. The construction period is short due to super-fast hardening, while the construction period is short due to the use of spray construction equipment, and a waterproof anti-rust coating (10) of a certain thickness is formed on the base surface (20), and uniform waterproof anti-rust performance without any weak spots. Can represent.

Figure 4 shows the construction method of the present invention according to the present invention, after pre-treatment such as removing contaminants from the base surface, and then spraying and applying the above-described polyurea waterproof anti-fog composition to form a waterproof anti-fog coating film. If necessary, it is possible to apply a primer to the pretreated base surface and then form a waterproof anti-rust coating.

Conditions of the two-component high-temperature and high-pressure spray device in the construction according to the present invention are as follows. It is preferable to maintain the pressure of the spray sprayer at 1500-3000 psi when the resin mixture and the hardener are mixed and collided. When the pressure is lower than 1500 psi, there is a problem of deterioration of properties due to uncured due to poor mixing, and when the pressure is higher than 3000 psi, a smooth painted surface cannot be obtained.

On the other hand, it is preferable to maintain the temperature of the main agent and the curing agent at 50 to 80°C during a mixed collision. When the temperature is 50°C or less, a problem of poor mixing occurs, and when the temperature exceeds 80°C, the reaction rate of the main material and the curing agent is accelerated, which is not preferable because a smooth painted surface cannot be obtained.

Conventional urethane and epoxy-based paints are two-component products, and must be sufficiently mixed by accurately mixing the main material and the curing agent. Failure to comply with this or depending on the working conditions may result in deterioration of properties due to uncuring. There is a disadvantage that it takes more than 24 hours. On the other hand, in the case of construction using the polyurea-based waterproof anti-reflective composition of the present invention, the curing time is short within a few minutes, so it not only improves construction efficiency by shortening working time and reducing labor costs, but also mechanical properties and abrasion resistance than conventional paints. It is also excellent.

Hereinafter, the present invention will be described in more detail by examples, but the scope of the present invention is not limited by the examples.

Physical property test

A physical property test was performed on the waterproof anti-fog composition prepared in Examples 1 to 3 and Comparative Examples 1 to 2.

1. Test items, test methods, and test results related to mechanical properties are shown in Table 2 below. In particular, the test report according to the results of the piercing load test for confirming the anti-root performance of the waterproof anti-fogging material according to Example 1 is shown in FIG. 5.

Looking at the mechanical properties and anti-rust performance of the waterproof anti-rust coating film with reference to Table 2, Examples 1 to 3 and Comparative Example 2 all showed excellent results in tensile strength, elongation, and tear strength, and penetration resistance. Also showed excellent results. However, in the case of Comparative Example 1, the content of the aliphatic diamine as a crosslinking agent was high and the content of the glass milled fiber was low, so it was confirmed that the performance in terms of tear strength and piercing resistance was reduced to a moderate degree. In terms of crack response at -20°C and 20°C, it was found that the performance at -20°C was deteriorated only in Comparative Example 2. This is because the main chain of the polymer is extended by the aliphatic diamine, but the content of the glass milled fiber is low, so that tensile strength and impact resistance are not strengthened, and the reinforcing effect on chemical properties such as corrosion resistance and heat resistance cannot be exhibited.

In addition, referring to FIG. 5, it was confirmed that the waterproof anti-reflective coating film according to Example 1 has an average piercing load of 27.4 N, and it can be confirmed that it exhibits a piercing load of 20 N or more, which is required in the anti-root performance.

In addition, with respect to the adhesion strength, Examples 1 to 3 and Comparative Example 1 showed excellent adhesion strength, but in the case of Comparative Example 2 in which the content of the epoxidized hydroxyl-terminated polybutadiene was low, the adhesion strength was reduced to a normal level. In terms of chemical resistance, Examples 1 to 3 and Comparative Example 1 exhibited excellent performance, but in the case of Comparative Example 2, acid resistance was very poor, and alkali resistance was also found to be reduced to a normal level. . This is due to the low content of epoxidized hydroxyl-terminated polybutadiene, which improves adhesion to the base surface and improves water resistance, chemical resistance, flexibility and impact resistance, so it cannot provide adhesion during curing and has chemical resistance. It means that it did not improve.

Looking at the eco-friendliness with reference to Table 3, the waterproofing repellent according to Examples 1 to 3 did not detect any lead, cadmium, mercury, hexavalent chromium, etc., and did not contain a solvent, thus satisfying the emission standard of volatile organic compounds. In the meantime, it can be confirmed that volatile aromatic hydrocarbons are not detected, so that the eco-friendliness is satisfied.

As described above, the waterproof anti-reflective composition according to the present invention incorporates glass milled fibers while controlling the content of the crosslinking agent in the subject so as to reinforce the mechanical and chemical properties of the polyurea waterproofing material with excellent physical properties, and to improve the adhesive strength. , By including epoxidized hydroxyl-terminated polybutadiene in the curing agent, it can be applied as a waterproof anti-rotation material that imparts anti-rotation properties such as tear strength and perforation load. Accordingly, the waterproof anti-fogging composition of the present invention is a polyurea waterproof anti-fogging material, which is quickly and easily integrated and flattened by a mechanized construction.
