Description

Smart Eco Crack Repair and Base Preparation Material and Odorless Smart Ultra-Fast Waterproofing Floor System Using the Material The present invention relates to a smart eco crack repair and surface preparation material and an odorless smart ultra-fast curing waterproof floor system using the same. Generally, after civil engineering and construction projects such as parking lots, hospitals, factories, commercial buildings, offices, and restaurants are completed, flooring materials are installed to protect the interior concrete floors while enhancing the exterior aesthetics. As flooring materials, synthetic resin paint-type floor finishes such as epoxy resin, urethane resin, and vinyl resin, as well as cement-based floor finishes, are used as finishing materials applied to concrete floor surfaces. Among them, the most widely used concrete floor finishing materials currently are synthetic resin paint-type finishes based on epoxy resin, urethane resin, and vinyl resin. The above epoxy and urethane resins have excellent flexibility, elasticity, dust resistance, and stain resistance, as well as excellent workability and quick-drying properties. In addition, they have excellent water resistance and the advantage of allowing the use of large amounts of various fillers. However, in conventional technology, flooring materials had problems such as lifting due to reduced initial adhesion when installed on the slab floor surface and cracking due to external impact. In particular, epoxy resins, urethane resins, and vinyl resins have a problem in that the use of petroleum-based diluents during construction results in high levels of VOCs, which have a negative impact on the health of workers and residents. FIG. 1 is an exemplary cross-sectional view showing the layer structure of a floor system according to the present invention. Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings. The smart eco crack repair and surface finishing material according to the present invention is a three-component type consisting of an inorganic agent, a main component, and a hardener, and when using it, it is preferable to mix the inorganic agent, the main component, and the hardener in a weight ratio of 9-10:2:1. In this case, the above-mentioned surface finishing material is used for both crack repair and surface preparation. For instance, it includes crack filling. The inorganic material constituting this surface preparation material consists of 60% by weight of silicon dioxide and 40% by weight of Portland cement. In this case, silicon dioxide is a material corresponding to CAS number 7631-86-9, which strengthens bonding strength, increases scratch resistance of the coated surface, prevents settling to improve stability, and has thickening and anti-sagging properties. In addition, Portland cement is a material corresponding to CAS number 65997-15-1, which enhances water resistance and has excellent crack and gap filling properties, contributes to securing strength and durability, and is a key inorganic binder for improving structural bonding strength and strength. In addition, the main component constituting the above surface preparation material consists of 10-20% by weight of bisphenol A diglycidyl ether, 10-20% by weight of bisphenol A-bisphenol A diglycidyl ether polymer (DGEBA), and the remainder being water. Here, bisphenol A diglycidyl ether is a substance corresponding to CAS number 1675-54-3, a high-performance organic binder, and is a very important component in the filling properties of a surface preparation material that maximizes adhesion to strengthen bonding, and provides chemical resistance, water resistance, excellent mechanical strength and wear resistance, and a shortened curing time. And, the bisphenol A-bisphenol A diglycidyl ether polymer (DGEBA) is as described above. In addition, the curing agent constituting the above surface preparation material consists of 1-10% by weight of tetraethylenepentamine, 1-10% by weight of diaminopolypropylene glycol, 1-10% by weight of m-xylylenediamine, 1-10% by weight of 2,4,6-tris(dimethylaminomethyl)phenol, 1-10% by weight of methoxy-substituted alkane, and the remainder being water. In this case, tetraethylenepentamine is a substance corresponding to CAS number 112-57-2, an ethyleneamine-based organic compound used as a major curing agent and curing accelerator in floor waterproofing systems, and is a key component that chemically reacts with the previously described bisphenol A diglycidyl ether (epoxy resin) to form a strong waterproof film. In addition, diaminopolypropylene glycol is a substance corresponding to CAS number 9046-10-0, chemically known as polyoxypropylene diamine or commercially as the Jeffamine D series, and has the advantage of enhancing the curing power of epoxy resin in floor waterproofing systems while providing flexibility and impact resistance. In addition, m-xylyl
