Description

Technical Field

[0001] The invention relates to the technical field of building mortar materials, and in particular to an active, lightweight, moisture-proof, mildew-proof and powder-proof YTV moisture-proof and heat-insulating mortar and a preparation method thereof. Background Art

[0002] Basements, as a crucial component of modern architecture, are involved in commercial, residential, and transportation applications. Due to their humid, enclosed environment, basements have long faced numerous challenges, including moisture resistance, waterproofing, thermal insulation, mildew resistance, and powdering resistance. Currently, basement walls commonly utilize a layered construction process, including waterproofing, thermal insulation, bonding, and finishing layers. However, each layer relies on different materials, and due to differences in physical properties, the compatibility of the various layers is insufficient. In the enclosed and humid environment of a basement, problems such as mildew, powdering, bulging, and cracking are highly likely to occur, seriously impacting the basement's functionality and lifespan.

[0003] The invention patent with application number 202210351289.6 discloses an active, lightweight, fireproof, mesh-free YT inorganic active wall insulation material, which includes a bottom adhesive layer, a middle insulation layer, a hydrophobic layer, a breathable layer and a flexible surface layer from the inside to the outside. This patent uses a microbubble process to strengthen the stability of the insulation layer and the formation of the grid structure, uses a multi-faceted surface, a polymer cavity structure and a bubble structure to block the conduction of heat, and uses the interweaving of coarse and fine fibers and fiber ethers and the bubble structure to achieve the purpose of material flexibility gradient and self-curing, overcoming the shortcomings of existing thermal insulation mortars in terms of high temperature resistance, water resistance, crack resistance, and air permeability, and achieving the effects of mesh-free crack resistance, thermal insulation and energy saving, and breathable and comfortable. Although this patent also provides a thermal insulation mortar, the thermal insulation mortar provided by this patent has poor waterproof and moisture resistance.

[0004] Patent application number 201620385726.6 discloses a YT inorganic lightweight aggregate polymer mesh-free wall insulation material. The insulation material comprises, from the outside in, a finishing layer, an anti-crack protective layer, an insulation layer, and a waterproof cured layer. The finishing layer is a siliceous material layer that absorbs formaldehyde. The anti-crack protective layer comprises anti-crack and anti-seepage mortar and an elastic primer. The insulation layer is a layer of inorganic lightweight aggregate material that resists heat flow conduction and reflects heat sources. The insulation layer is provided with a porous cavity and a barrier material. A bonding layer is also provided between the insulation layer and the waterproof cured layer. The wall insulation material prepared by this patent is also not waterproof or moisture-proof, making it unsuitable for use in damp, enclosed basements.

[0005] Therefore, it is of great significance to provide a YTV moisture-proof and thermal insulation mortar that is active, lightweight, moisture-proof, mildew-proof, compression-resistant, and powder-proof. Summary of the Invention

[0014] Furthermore, the density of the ceramsite is 200-1000 kg / m 3 , thermal conductivity 0.2-0.55W / (m·K).

[0015] Furthermore, the particle size of the fly ash beads is 300-800 microns, and the density is 0.6-0.8 g / m 3 , thermal conductivity 0.11-0.25W / (m·K).

[0016] Furthermore, the yttrium powder is 5-10 mm.

[0017] Furthermore, the organic silicon water repellent is selected from any one of potassium methyl silicate or sodium methyl silicate.

[0018] Furthermore, the reinforcing agent includes a fluorine-containing emulsion. Preferably, the carbon number of the fluorine-containing emulsion is 3-10. More preferably, the fluorine-containing emulsion is perfluorohexylethyl methacrylate.

[0019] Furthermore, the preparation method of the modified graphene oxide is:

[0020] The graphene oxide was ultrasonically dispersed in an organic solvent for 3-8 minutes, followed by the addition of palmitamine and continued ultrasonic dispersion for 0.5-2 hours. The temperature was then raised to 70-85°C and stirred for reaction for 18-36 hours. After the reaction was completed, the mixture was cooled to room temperature and washed with an organic solvent and deionized water for 2-5 times, and then dried at low temperature to obtain modified graphene oxide.

[0021] Furthermore, the organic solvent includes but is not limited to anhydrous ethanol. Preferably, the organic solvent is anhydrous ethanol.

[0022] Furthermore, the mass volume ratio of the graphene oxide to anhydrous ethanol is 1-3:100-500. Preferably, the mass volume ratio of the graphene oxide to anhydrous ethanol is 1:400.

[0026] The active, lightweight, moisture-proof, mildew-proof and powder-proof YTV moisture-proof and thermal insulation mortar is prepared using a conventional method for preparing mortar in the art, including but not limited to mixing various raw materials to prepare the moisture-proof and thermal insulation mortar.

[0027] The composition of YTV is: an aggregate of inorganic rock (Yan) minerals, a high melting point substitute for trace yttrium elements (Yttrium); clay minerals (Tu) and tilleyite powder (Tilleyite); and cementitious materials (EVA). The important materials come from Y-, T- and V-head materials, so it is named YTV.

[0028] The moisture-proof and mildew-proof properties of the active, lightweight, moisture-proof, mildew-proof and powder-proof YTV moisture-proof and thermal insulation mortar provided by the present invention come from the synergistic effect of multiple raw materials. The anti-powdering property is that many cementitious materials act on the surface of the moisture-proof and thermal insulation layer to form a wear-resistant, weather-resistant and stable surface layer. In addition, the bubble chambers formed by the blending of EVA, structural materials and silicone hydrophobic agents in the mortar fill the grid, ensuring the stability of the frame structure. At the same time, the fly ash beads and ceramsite work together to further strengthen the firmness of the insulation layer frame while enhancing the heat barrier effect. By adding raw materials with water-retaining function to the mortar, the present invention can achieve the gradualness of the hydration reaction of the cement cementitious material, ensure a more balanced stress release during the formation of the thermal insulation layer, avoid the situation where the stress is released too quickly and causes local cracking, and realize the self-maintenance function of the YTV moisture-proof and thermal insulation mortar. It is also a manifestation of the multifunctional effects of activity, lightweight, moisture-proof, mildew-proof, pressure-resistant and powder-proof.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The invention solves the defects of layered construction and incompatible materials of each layer in basement projects, and provides a YTV moisture-proof and thermal insulation mortar which is lightweight, moisture-proof, mildew-proof and powder-proof.

[0031] The present invention forms a molecular film layer through a chemical reaction between the hydrophobic active group and the matrix material, which is adsorbed in the pores to present an "anti-capillary effect" that blocks the capillaries, helping to improve the moisture and mildew resistance of the mortar.

[0032] The present invention forms a fluorocarbon chain barrier in the mortar pores by introducing a fluorine-containing emulsion, blocking the water penetration path, thereby reducing the mortar's adsorption of liquid water and moisture, and improving the mortar's moisture-proof stability. However, although the introduction of fluorocarbon emulsion can improve the mortar's moisture-proof and water-resistant properties to a certain extent, it mainly solves the problem of surface waterproofing and cannot block the erosion of non-liquid water and structural water, resulting in the problem of wall mold easily occurring after construction. For this reason, the present invention adds stearic acid amide polyamine, modified graphene oxide and nano-silica to the moisture-proof and thermal insulation mortar formula. The addition of stearic acid amide polyamine, modified graphene oxide and nano-silica has the effects of extending the water vapor diffusion path, reducing the mortar porosity, and improving the mortar's bonding strength and compressive performance. The present invention further improves the mortar's moisture-proof and water-resistant properties by selecting specific raw materials and rationally compounding the raw materials used.

[0033] The YTV moisture-proof and thermal insulation mortar prepared by the present invention exhibits the lotus bead phenomenon in the dry powder state, which lasts for more than 96 hours. When the molded test block is completely dry, the lotus bead phenomenon appears on the side, which lasts for more than 24 hours. The fault can still maintain the lotus bead phenomenon for more than one hour after the capillaries are destroyed.

[0034] When the YTV moisture-proof and heat-insulating mortar prepared by the present invention is used in basements and confined spaces, condensation does not occur, mildew does not occur, and the surface has no sense of erosion or moistness. After long-term use, destructive tests are conducted, and the inner layer material has not undergone any changes, and the fault still has the lotus leaf bead water-repellent phenomenon.

[0035] The moisture-proof and heat-insulating mortar provided by the present invention can make the wall have a breathing function. Under the premise of being waterproof, it shows extremely strong air permeability, eliminating the stuffiness in the confined space. In addition, the air-permeable and water-tight wall can also regulate the humidity in the air and generate microcirculation, and the wall will not have condensation and mildew.

[0036] The YTV moisture-proof and thermal insulation mortar prepared by the present invention is easy to construct. Unlike other moisture-proof and thermal insulation mortar materials, the mortar of the present invention does not require multi-level operation and can achieve the desired effect through one-time molding. The construction cost is only one-fifth of that of other materials. DETAILED DESCRIPTION
