[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A waterproof, fireproof, heat-insulating, Xicai stone water-enclosed sand, characterized in that it is composed of the following raw materials in parts by weight:

[0007] Sand-containing base paint: 300-400 parts of water, 3-6 parts of dispersant, 1-3 parts of defoamer, 5-8 parts of film-forming aid, 1-2 parts of multifunctional additive, 200-300 parts of styrene-acrylic emulsion, 500-700 parts of colored sand, 100-150 parts of expanded vermiculite, 80-120 parts of hollow ceramic microspheres, and 30-50 parts of flame retardant;

[0008] Protective glue: 80-100 parts of water, 2-4 parts of cross-linking agent, 2-4 parts of thickener;

[0009] Continuous phase emulsion: 50-80 parts of water, 150-250 parts of styrene acrylic emulsion, 2-4 parts of propylene glycol, and 3-6 parts of film-forming aid.

[0010] As a preferred solution of the present invention, the preparation method of the sand-containing base paint comprises: adding water, dispersant, defoamer, film-forming aid, and multifunctional additive into a stirring container, stirring evenly at a speed of 500-800 rpm, then adding styrene acrylic emulsion, and continuing stirring for 15-20 minutes to make it evenly mixed; then, slowly adding colored sand, expanded vermiculite, hollow ceramic microspheres and flame retardant, increasing the stirring speed to 1000-1200 rpm, and stirring for 30-40 minutes until it is evenly dispersed.

[0011] As a preferred solution of the present invention, the preparation method of the protective glue comprises: slowly adding a crosslinking agent into water, stirring evenly at a speed of 300-500 rpm, then adding a thickener, and continuing stirring for 10-15 minutes.

[0012] As a preferred solution of the present invention, the method for preparing the continuous phase emulsion comprises: adding water, styrene acrylic emulsion, propylene glycol and film-forming aid into a stirring container, and stirring evenly at a speed of 600-800 rpm.

[0013] As a preferred solution of the present invention, its preparation method comprises the following steps: mixing the sand-containing base paint and the protective glue in a certain proportion, uniformly granulating, and finally adding the continuous phase emulsion, stirring at a speed of 800-1000 rpm for 20-30 minutes to obtain water-coated sand with waterproof, fireproof, thermal insulation and heat preservation.

[0014] As a preferred solution of the present invention, the coating formed by the water-coated sand after drying should have the following performance indicators: in terms of waterproof performance, it can withstand a water pressure of at least 0.5 MPa without leakage; in terms of fireproof performance, it can delay the spread of fire for at least 30 minutes under standard combustion test conditions; in terms of thermal insulation performance, the thermal conductivity should be no more than 0.06 W / (m·Kelvin).

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this solution, the water-based sand coating can withstand a water pressure of at least 0.5 MPa without leakage, which shows that it has excellent waterproof ability. In practical applications, this strong waterproof performance can effectively block the intrusion of rainwater, ensure that the interior of the building remains dry, avoid the impact of rainwater erosion on the structural stability of the building, and reduce structural damage and corrosion problems caused by water penetration, thereby extending the service life of the building.

[0017] 2. In this solution, under standard combustion test conditions, the coating can delay the spread of fire for at least 30 minutes, which provides valuable time for responding to fire. When a fire occurs, the barrier effect of the coating can slow down the spread of fire, buy more time for the evacuation of personnel, increase the chances of escape, and improve the protection of life safety.

[0018] 3. In this solution, the thermal conductivity of the coating is no more than 0.06 W / (m·Kelvin), which means that it has excellent thermal insulation properties and can effectively reduce the transfer of heat. In summer, it can block external heat from entering the room, lower the indoor temperature, and reduce the frequency of use and energy consumption of air conditioners, thereby achieving the goal of energy saving. In winter, it can reduce indoor heat loss, keep the room warm, reduce heating energy consumption, and save heating costs for users. This thermal insulation performance not only helps to improve the energy efficiency of buildings, but also reduces energy consumption to the environment, meets the requirements of energy conservation and environmental protection, and has positive significance for sustainable development. DETAILED DESCRIPTION

[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1

[0021] The present invention provides the following technical solutions:

[0022] A waterproof, fireproof, heat-insulating, Xicai stone water-enclosed sand, characterized in that it is composed of the following raw materials in parts by weight:

[0023] Sand-containing base paint: 300-400 parts of water, 3-6 parts of dispersant, 1-3 parts of defoamer, 5-8 parts of film-forming aid, 1-2 parts of multifunctional additive, 200-300 parts of styrene-acrylic emulsion, 500-700 parts of colored sand, 100-150 parts of expanded vermiculite, 80-120 parts of hollow ceramic microspheres, and 30-50 parts of flame retardant;

[0024] Protective glue: 80-100 parts of water, 2-4 parts of cross-linking agent, 2-4 parts of thickener;

[0025] Continuous phase emulsion: 50-80 parts of water, 150-250 parts of styrene acrylic emulsion, 2-4 parts of propylene glycol, and 3-6 parts of film-forming aid.

[0026] In a specific embodiment of the present invention, the water-enclosed sand with waterproof, fireproof, heat-insulating and thermal insulation properties is an innovative building material with multiple excellent properties.

[0027] In the sand-containing base paint, water is the main solvent, and its content is between 300-400 parts, providing a dispersion medium for each component. The function of the dispersant is to ensure that particles such as colored sand, expanded vermiculite and hollow ceramic microspheres are evenly dispersed in the system to avoid agglomeration. The content is 3-6 parts. The defoamer is used to eliminate bubbles generated during the production and use of the system to ensure the quality of the coating. The dosage is 1-3 parts. The film-forming aid helps the styrene-acrylic emulsion to form a continuous and uniform film during the film-forming process. The content is 5-8 parts. The multifunctional additive can adjust the pH value and other properties of the system. The dosage is 1-2 parts. Styrene-acrylic emulsion is the main binder, with a content of 200-300 parts. It can firmly bond the components together to form a stable coating. Colored sand gives water-coated sand rich colors and textures, and its dosage is 500-700 parts. Expanded vermiculite has good thermal insulation properties and can expand to form an insulation layer when heated. The content is 100-150 parts. Hollow ceramic microspheres also have the function of heat insulation and can reduce the weight of the material, with a dosage of 80-120 parts. The addition of flame retardant makes water-coated sand have fireproof properties, with a content of 30-50 parts.

[0028] The protective glue is composed of water, a crosslinking agent and a thickener. The water content is 80-100 parts, which is used as a solvent. The crosslinking agent can crosslink the components in the protective glue to improve its stability and performance. The dosage is 2-4 parts. The thickener is used to adjust the viscosity of the protective glue so that it can play a better role during use. The dosage is 2-4 parts.

[0029] In the continuous phase emulsion, the water content is 50-80 parts, which provides a dispersion medium for the styrene acrylic emulsion. As the continuous phase, the styrene acrylic emulsion has a content of 150-250 parts, which can wrap the sand-containing base paint and protective glue in it to form a stable water-in-sand system. Propylene glycol is used as an auxiliary agent to improve the stability and performance of the emulsion, and the dosage is 2-4 parts. The role of the film-forming aid is similar to that of the film-forming aid in the sand-containing base paint, which helps the styrene acrylic emulsion to form a continuous and uniform film during the film-forming process, and the content is 3-6 parts.

[0030] This water-packed sand integrates waterproof, fireproof, thermal insulation and other properties through a reasonable formula design, providing a high-quality material choice for building exterior wall decoration and protection.

[0031] Specifically in this scheme, the preparation method of the sand-containing base paint includes: adding water, dispersant, defoamer, film-forming aid, and multifunctional additive into a stirring container, stirring evenly at a speed of 500-800 rpm, then adding styrene acrylic emulsion, and continuing to stir for 15-20 minutes to make it evenly mixed; then, slowly adding colored sand, expanded vermiculite, hollow ceramic microspheres and flame retardant, increasing the stirring speed to 1000-1200 rpm, stirring for 30-40 minutes, until evenly dispersed.

[0032] In this embodiment: in the preparation process of the sand-containing base paint, water, dispersant, defoamer, film-forming aid and multifunctional additive are first added to a stirring container in sequence. These components are stirred in the stirring container at a speed of 500-800 rpm, and such a speed can ensure that the components are initially mixed uniformly, and will not cause insufficient mixing due to too slow stirring speed, nor will it generate excessive heat or cause splashing of components due to too fast speed.

[0033] After the above ingredients are stirred evenly, add styrene acrylic emulsion. Styrene acrylic emulsion is the main binder. Continue stirring for 15-20 minutes after adding it. This period of time allows the styrene acrylic emulsion to fully blend with the previous ingredients to form a relatively stable mixed system.

[0034] Next, slowly add the colored sand, expanded vermiculite, hollow ceramic microspheres and flame retardant. The reason for slow addition is to avoid uneven stirring or caking due to adding too much at one time. After adding these ingredients, increase the stirring speed to 1000-1200 rpm. A higher stirring speed can better disperse the granular colored sand and the specially shaped expanded vermiculite and hollow ceramic microspheres in the system, while also ensuring that the flame retardant is fully mixed with other ingredients. Stirring continues for 30-40 minutes. After such a long period of high-speed stirring, the various components in the sand-containing base paint can be evenly dispersed, thereby ensuring the quality and stable performance of the sand-containing base paint.

[0035] Specifically in this solution, the preparation method of the protective glue includes: slowly adding a crosslinking agent into water, stirring evenly at a speed of 300-500 rpm, then adding a thickener, and continuing stirring for 10-15 minutes.

[0036] In this embodiment: when preparing the protective glue, first prepare an appropriate amount of water and place it in a stirring container. Then, slowly add the crosslinking agent to the water. During the addition process, the stirring speed should be controlled to 300-500 rpm to ensure that the crosslinking agent can be evenly dispersed in the water to avoid agglomeration or excessive local concentration. After stirring evenly, add the thickener to the system and continue stirring for 10-15 minutes to allow the thickener to fully play its role and adjust the viscosity and stability of the protective glue.

[0037] During the entire stirring process, attention should be paid to the control of the stirring speed to ensure that the components can be fully mixed to form a uniform protective glue system. In addition, attention should also be paid to the order of adding raw materials and the stirring time, as these factors will affect the performance and quality of the protective glue.

[0038] Through the above detailed preparation method, a protective adhesive with stable performance and reliable quality can be obtained, which provides an important component for the preparation of water-coated sand for waterproofing, fireproofing, thermal insulation and heat preservation.

[0039] Specifically in this embodiment, the method for preparing the continuous phase emulsion comprises: adding water, styrene acrylic emulsion, propylene glycol and film-forming aid into a stirring container, and stirring evenly at a speed of 600-800 rpm.

[0040] In this embodiment: when preparing the continuous phase emulsion, water, styrene acrylic emulsion, propylene glycol and film-forming aid are added to a stirring container in a certain order. Water is added first to provide a basis for subsequent mixing. Then, styrene acrylic emulsion, propylene glycol and film-forming aid are added in sequence to ensure that each component is fully in contact.

[0041] During the process of adding raw materials, start the stirring device and control the stirring speed at 600-800 rpm. Such a stirring speed can effectively mix the components together to form a uniform emulsion system. The stirring time should be long enough to ensure that the components are fully dispersed and reach a uniform state.

[0042] In addition, during the mixing process, attention should be paid to the sealing of the mixing container to prevent the volatilization of raw materials or the entry of external impurities. At the same time, the normal operation of the mixing device should be ensured to ensure the mixing effect.

[0043] Through the above detailed preparation method, a continuous phase emulsion with stable quality and good performance can be obtained, which provides important support for the preparation of water-coated sand with waterproof, fireproof, thermal insulation and heat insulation.

[0044] Specifically in this scheme, the preparation method includes the following steps: mixing the sand-containing base paint and the protective glue in a certain proportion, uniformly granulating, and finally adding the continuous phase emulsion, stirring at a speed of 800-1000 rpm for 20-30 minutes to obtain water-coated sand with waterproof, fireproof, thermal insulation and heat preservation.

[0045] In this embodiment: First, before preparation, it is necessary to ensure that the quality and performance of the sand-containing base paint and the protective glue meet the requirements. The ratio of the sand-containing base paint and the protective glue should be determined according to the specific formula and test results to ensure that the performance of the final product is optimal.

[0046] Place the sand-containing base paint and protective glue in a suitable mixing container and start the stirring equipment. The speed of the stirring equipment should be controlled within a certain range to ensure that the two can be fully mixed and evenly mixed. During the stirring process, pay attention to the state of the mixture to ensure that there is no lumps or unevenness.

[0047] After uniform mixing, a uniform granulation step is performed. This step can use appropriate granulation equipment or methods to make the mixture into uniform granules. The size and shape of the granules should be controlled according to actual needs to ensure the subsequent processing and use effects.

[0048] Next, add the continuous phase emulsion to the granulated mixture. Start the stirring device again, adjust the speed to 800-1000 rpm, and stir. The stirring time is 20-30 minutes. During this process, the continuous phase emulsion can fully blend with the mixture to form a stable system.

[0049] During the mixing process, pay close attention to the mixing situation to ensure that the mixture is fully mixed and evenly mixed without stratification or separation. At the same time, pay attention to controlling the mixing time and speed to avoid product quality problems caused by over-mixing or under-mixing.

[0050] Finally, after the above steps, a water-in-sand product with waterproof, fireproof, heat-insulating and heat-insulating properties can be obtained. During the preparation process, the parameters and conditions of each link should be strictly controlled to ensure that the quality and performance of the product meet the requirements.

[0051] In addition, it should be noted that factors such as ambient temperature and humidity during the preparation process may also affect the performance of the product, so production should be carried out under appropriate environmental conditions as much as possible. At the same time, operators should have certain professional knowledge and skills and be familiar with the preparation process and equipment operation to ensure the smooth progress of the production process.

[0052] Specifically in this scheme, the coating formed by the water-coated sand after drying should have the following performance indicators: in terms of waterproof performance, it can withstand a water pressure of at least 0.5 MPa without leakage; in terms of fireproof performance, under standard combustion test conditions, it can delay the spread of fire for at least 30 minutes; in terms of thermal insulation performance, the thermal conductivity should be no more than 0.06 W / (m·Kelvin).

[0053] In this embodiment: In terms of waterproof performance, the water-in-sand coating can withstand a water pressure of at least 0.5 MPa without leakage, which means that it has excellent waterproof ability. When the coating is applied to the surface of a building, it can effectively prevent water penetration and protect the interior of the building from rain erosion. This high waterproof performance can extend the service life of the building and reduce the cost of repair and maintenance.

[0054] In terms of fireproof performance, the coating can delay the spread of fire for at least 30 minutes under standard combustion test conditions. This performance indicator is crucial for the fire safety of buildings. When a fire occurs, the coating can play a certain barrier role, slowing down the spread of the fire and buying precious time for evacuation and fire fighting. In addition, coatings with good fireproof performance can also reduce the losses caused by fire and improve the safety of buildings.

[0055] In terms of thermal insulation performance, the thermal conductivity of the coating should be no greater than 0.06 W / (m·Kelvin). This indicates that the coating has a low thermal conductivity and can effectively reduce the heat transfer between the interior of the building and the outside world. In summer, it can block external heat from entering the room and reduce the energy consumption of air conditioning; in winter, it can reduce the loss of indoor heat and save heating energy. This thermal insulation performance helps to improve the energy efficiency of buildings and reduce the impact on the environment.

[0056] In order to ensure that the water-based sand coating can achieve these performance indicators, the quality of raw materials, the proportion of the formula and the specifications of the construction process need to be strictly controlled during the production and construction process. At the same time, corresponding tests and inspections are also required to verify whether the performance of the coating meets the requirements.

[0057] In addition, with the continuous advancement of science and technology and the improvement of people's requirements for building performance, higher requirements may be placed on the performance indicators of water-based sand coatings in the future. Therefore, relevant research and development work should be carried out continuously to promote the continuous improvement and perfection of the performance of water-based sand products.

[0058] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
