[0002] In the construction industry, waterproofing construction is a key step in ensuring the durability and functionality of structures. Traditional waterproofing methods usually involve a multi-step process, including thorough cleaning of the base surface, application of multiple layers of different types of waterproofing materials, and maintenance at different stages. Although these methods can provide waterproof protection to some extent, they have the following major disadvantages:

[0003] The construction is complicated and time-consuming: Traditional waterproofing technology requires multiple stages of application and maintenance, and each stage must wait until the previous step is completely dry before proceeding, which greatly prolongs the construction period.

[0041] Figure 1 It is a process flow chart of the present invention. DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the specification 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.

[0043] Please see attached Figure 1 The embodiment of the present invention provides a composite waterproof material construction preparation process, which aims to solve the problem that traditional waterproof construction is time-consuming and multi-stage construction is prone to damage to the waterproof layer, and improve the integrity and durability of the waterproof layer.

[0044] Specifically, the process includes the following steps:

[0045] S1. Cleaning and treatment of the base surface

[0046] Before construction, first ensure that the base surface is dry and flat. Use a high-pressure water gun or a hard brush to thoroughly clean the impurities, dust, oil, etc. on the base surface. If necessary, use sandpaper or a grinder to grind it to make the base surface reach the ideal roughness and enhance the adhesion of subsequent materials. This step is the prerequisite for a good waterproof effect, which can significantly reduce the gap between the subsequent materials and the base surface and improve the sealing of the waterproof layer.

[0047] S2. Mix the penetrating crystallization waterproof coating and cement mortar in proportion.

[0048] The penetrating crystallization waterproof coating that meets the GB / T 18445-2011 standard is mixed with cement mortar that meets a certain water-cement ratio. The penetrating crystallization waterproof coating contains chemical components that can react with free calcium ions in the cement mortar to generate insoluble crystals, which can fill the capillary pores and prevent water from passing through. The mixing ratio is precisely controlled within the recommended dosage range of the coating to ensure the uniformity and reaction effect of the final mixture.

[0049] S3. Apply the mixed penetrating crystallization waterproof coating and cement mortar evenly on the base surface

[0050] Use a scraper, roller or spray equipment to evenly apply the mixture on the cleaned base surface. The coating thickness is usually 1-2mm, ensuring that all cracks and unevenness are covered. The penetrating crystalline waterproof coating in this step can penetrate into the tiny cracks inside the base surface, react with the cement component, and form a solid waterproof layer.

[0051] S4. Immediately lay the wet-laid waterproof membrane on the coated base surface

[0052] Before the applied penetrating crystal coating is completely cured, wet-laid waterproofing membrane should be laid immediately. The membrane should be laid tightly without gaps, and ensure that the overlap is sufficient to provide double-layer protection. This can take advantage of the wet state of the penetrating crystal coating to form a better bond with the bottom of the membrane, thereby increasing the integrity of the waterproof layer.

[0053] S5. Compact the laid waterproof membrane

[0054] Use professional compaction equipment such as a roller to roll on the laid membrane to ensure that there is no air between the membrane and the base surface and that it fits perfectly. This step is key to ensure that the waterproof membrane is firmly bonded to the base surface to avoid future water penetration and membrane blistering.

[0055] S6. Seal the joints and details of the rolls

[0056] The same penetrating crystallization paint and cement mortar mixture is used to seal the joints of the membrane, and special attention is paid to the treatment of complex parts such as pipe crossings and corners. These parts are often high-risk areas for leakage, and strengthening treatment can effectively prevent future leakage problems.

[0057] S7. Perform initial maintenance

[0058] After all construction is completed, the waterproof layer needs to be properly maintained. Keep the waterproof layer moist to prevent it from drying out too quickly and causing cracks. The maintenance period is usually 24 to 48 hours. During this period, avoid people walking or heavy objects pressing on it.

[0059] The composite waterproof material construction preparation process of the present invention significantly improves the durability and reliability of the waterproof effect by combining the dual protection mechanism of penetrating crystallization coating and wet-laid waterproof membrane. The construction steps are simplified, the construction time is reduced, and the waterproof performance of the overall structure is greatly improved through the dual action mechanism of chemistry and physics. In addition, by reducing the maintenance time and increasing the construction speed, this process can be applied to projects with urgent construction period requirements, providing a more economical and efficient waterproof solution for construction projects.

[0060] In a preferred embodiment of the present invention, the processing of the base surface comprises the following steps:

[0061] S11. Use a high-pressure water gun or a hard-bristle brush to thoroughly clean the construction surface.

[0062] Before waterproofing, it is crucial to thoroughly clean the construction surface. This step uses a high-pressure water gun or a hard-bristle brush to thoroughly remove all impurities on the surface, including dust, oil, loose particles, etc. The high-pressure water gun can effectively remove the accumulation of the surface and contamination that is difficult to clean manually, while the hard-bristle brush can be used for more stubborn stains or rougher surfaces. The thorough execution of this step creates ideal conditions for good adhesion of subsequent materials and prevents the waterproof layer from falling off or leaking due to impurities on the surface.

[0063] S12. Repair cracks and uneven areas on the base surface with repair mortar

[0064] Cracks and uneven areas on the base surface are potential water seepage points and must be repaired thoroughly to ensure the integrity of the waterproof layer. In this step, all cracks and potholes are filled and leveled using a repair mortar with a specific ratio. The repair mortar should be of a type with good adhesion and compressive strength to ensure durability and waterproofing of the repaired area. The repair mortar needs to be fully cured and dried to ensure good bonding with the penetrating crystalline waterproof coating and cement mortar.

[0065] S13. Apply base treatment agent on the base surface

[0066] After cleaning and repairing, applying a base treatment is a key step to improve the adhesion of the waterproof layer. Base treatments usually contain chemical components that promote adhesion, which can enhance the adhesion of subsequent waterproofing materials to the substrate. In this step, the base treatment is evenly applied to cover all repaired and unrepaired areas to form a uniform bonding layer. The base treatment not only improves adhesion, but also seals the tiny pores of the substrate to prevent moisture from passing through.

[0067] Through thorough cleaning and uniform repair, irregularities and potential weaknesses of the base surface are eliminated, laying a solid foundation for the integrity and durability of the waterproof layer. The use of base treatment agents enhances the adhesion between the waterproof material and the base surface, effectively avoiding the peeling of the waterproof layer due to poor bonding. At the same time, the standardized base surface treatment process ensures that each step of construction meets the expected quality standards, reducing the need for repairs and maintenance that may occur in the future.

[0068] In a preferred embodiment of the present invention, the coating amount of the base treatment agent is 0.1-0.2 kg / m 2 , 0.1-0.2kg / m 2 The coating amount is sufficient to form a continuous film covering all micropores and uneven surfaces of the substrate. This is the first line of defense to prevent moisture from penetrating into the substrate. This measurement is designed to optimize the performance of the substrate treatment agent, ensuring economic efficiency without sacrificing waterproofing effect.

[0069] In a preferred embodiment of the present invention, the mixing ratio of the penetrating crystalline waterproof coating and the cement mortar is 1.37kg-1.5kg / m 2 The penetrating crystalline waterproof coating is mixed with cement mortar with a water-cement ratio of 0.4-0.5.

[0070] Specifically, the principle of determining the mixing ratio

[0071] In the preferred embodiment of the present invention, the selection of the mixing ratio of the permeable crystalline waterproof coating and the cement mortar is of key significance to ensure that the waterproof layer has good physical and chemical properties. The setting of the mixing ratio is based on the following important considerations:

[0072] Effective chemical reaction: Penetrating crystalline waterproof coating contains active chemical components that can react with free calcium ions in cement to form insoluble crystals. These crystals fill the micropores in the cement mortar and prevent water from passing through. The recommended dosage of the coating is 1.37kg-1.5kg / m 2 It is based on calculations to achieve the best chemical reaction and coverage effect.

[0073] Optimized ratio of cement mortar: A water-cement ratio of 0.4-0.5 ensures that the mortar has sufficient fluidity and adhesion while maintaining structural stability. Too high a water-cement ratio will lead to a decrease in the strength of the mortar, while too low a ratio will affect the workability of the mortar and the uniform distribution of the waterproof coating.

[0074] In summary, the preferred embodiment of the present invention ensures the high performance of the waterproof layer and the economic efficiency of the construction through precise material ratio, and is suitable for various construction projects that require high-standard waterproofing treatment.

[0075] In a preferred embodiment of the present invention, the step of mixing the penetrating crystalline waterproof coating with the cement mortar comprises:

[0076] S21: Precisely meter the penetrating crystalline waterproof coating in proportion

[0077] Use precision weighing equipment to weigh the desired amount (1.37kg-1.5kg / m 2 ) Accurately meter the amount of penetrating crystalline waterproof coating. This step ensures that each square meter of the base surface receives enough coating to form an effective waterproof layer.

[0078] Accurate metering is a prerequisite for ensuring that the chemical reaction proceeds fully. Excess or insufficient metering may affect the final waterproofing effect and the economic use of the material.

[0079] S22: Add the measured penetrating crystallization waterproof coating into the cement mortar

[0080] Evenly sprinkle the measured penetrating crystallization waterproof coating into the prepared cement mortar. The water-cement ratio of the mortar should be controlled between 0.4-0.5 to maintain good fluidity and bonding strength.

[0081] The uniform addition in this step is to ensure that the paint particles are evenly dispersed in the mortar to avoid the formation of clumps, which is crucial for the chemical reaction of the paint and cement mortar.

[0082] S23: Use a mechanical stirring device at 300-500 rpm for 3-5 minutes to ensure uniform mixing

[0083] Use a mechanical stirrer to stir the penetrating crystallization paint and cement mortar at a speed of 300-500 rpm for 3-5 minutes. High-speed stirring helps to break up the paint particles and ensure the uniformity of the mixture.

[0084] Mechanical stirring can effectively disperse the paint particles and promote full contact and chemical reaction between the paint and cement mortar, which is the key to forming a dense and uniform waterproof layer. The precise control of stirring speed and time is to maximize the mixing efficiency while preventing the material from starting to solidify due to excessive stirring.

[0085] Through precise material metering and uniform mixing process, the waterproof layer can be guaranteed to have excellent sealing and durability. After the penetrating crystallization coating is evenly distributed in the mortar, it can effectively close the micropores of the base surface and improve the anti-penetration ability of the waterproof layer. And the precisely controlled mixing ratio and stirring process reduce the problems that may occur during construction, such as material lumps, uneven distribution, etc., thereby improving the reliability of construction and the overall quality of the waterproof layer.

[0086] In a preferred embodiment of the present invention, the coating thickness of the mixed penetrating crystallization coating and cement mortar is 1-2 mm.

[0087] A thickness of 1-2mm is enough to form a continuous and uniform waterproof layer. This thickness of coating can effectively seal the tiny cracks and pores on the substrate to prevent water from penetrating. This thickness range is enough for the active ingredients in the penetrating crystallization coating to fully react chemically with the ingredients in the cement mortar to form solid insoluble crystals and enhance waterproofness. Too thick a coating may cause uneven drying, increased internal stress, cracks or peeling. A thickness of 1-2mm can ensure that the coating dries evenly and reduce the risk of cracks.

[0088] In a preferred embodiment of the present invention, the laying steps of the wet-laid waterproofing membrane include:

[0089] S41: Lay the coil on the coated base surface to ensure that the coil is tightly bonded to the base surface.

[0090] Lay the roll on the base surface coated with the mixture of penetrating crystalline waterproof coating and cement mortar. Before laying, check whether the base surface is dry and the coating is even. Start from one end and gradually unroll the roll to ensure that the roll is flat and wrinkle-free. When laying, pay attention to the edge alignment to avoid excessive or insufficient overlap. Use appropriate adhesives or welding techniques to fix the edges and overlaps of the roll to enhance the sealing of the joints.

[0091] Tight bonding is the key to waterproofing effectiveness. Good adhesion between the membrane and the substrate can prevent moisture penetration and membrane movement.

[0092] S42: Use a compaction roller weighing 10-20kg to compact the roll 3-5 times per square meter to ensure complete adhesion between the roll and the base surface and to expel air.

[0093] Use a compaction roller with a specified weight (10-20kg) to roll from one end to the other on the laid roll. The compaction process needs to be carried out evenly, at least 3-5 times per square meter, to ensure that all parts of the roll are compacted. Pay special attention to the seams and edge areas of the roll to ensure that there are no air bubbles and unadhered parts in these areas.

[0094] Compaction is an important step to ensure that the membrane is fully adhered to the substrate. Through physical pressure, the bubbles in the membrane are expelled, and the membrane can better fit the coating to form a seamless waterproof layer. Proper compaction can also increase the friction of the membrane to prevent displacement or blistering of the membrane in subsequent use.

[0095] In a preferred embodiment of the present invention, the seam processing step of the coiled material comprises:

[0096] Before laying the roll, plan the location of the joints in advance to ensure that the overlap width of each roll is between 100-150mm.

[0097] During the membrane laying process, the mixed penetrating crystalline coating and cement mortar are applied to the predetermined joint areas, especially in the overlapping parts.

[0098] Apply the mixture precisely to ensure that the entire joint area is covered, taking care to prevent too thick or too thin a coat.

[0099] Using a mixture of penetrating crystallization paint and cement mortar for joint bonding can take advantage of the property of penetrating crystallization paint, which is the ability to form crystals inside the material after contact with water, filling gaps and cracks, thereby preventing further water penetration. The overlap width of 100-150mm provides enough area to form a strong bond, preventing cracks and leaks at the joints.

[0100] By using a mixture of penetrating crystallization coating and cement mortar at the joints, the various parts of the membrane can be effectively combined into a continuous waterproof layer. This method not only improves the mechanical strength of the joints, but also enhances the waterproof performance through chemical reactions. The joints are potential leakage points. Through scientific joint treatment methods, the possibility of leakage is greatly reduced, ensuring the integrity and effectiveness of the entire waterproof system.

[0101] In a preferred embodiment of the present invention, the processing step of the detail position includes:

[0102] S61: Use penetrating crystallization paint and cement mortar to strengthen the edges, corners, pipe roots and other details

[0103] Before working on these details, thoroughly clean and prepare the surface to remove any dust, grease or other substances that may affect adhesion. Mix the penetrating crystallization paint with cement mortar in the proportions determined previously. Use a brush or scraper to evenly apply the mixed material to details such as corners, internal and external corners and pipe roots, ensuring uniform coverage and a layer thickness that meets the design requirements.

[0104] Penetrating crystalline coatings react with cement components during the hardening process of cement mortar to form crystals, which can fill tiny cracks and pores and provide an additional waterproof barrier. These areas are prone to potential leakage points due to their complex shapes or connecting multiple structural components, so enhanced treatment is required to ensure the continuity and integrity of the waterproof layer.

[0105] S62: Add a layer of waterproof membrane with a width of 200-300mm to reinforce these details

[0106] In the detailed position where the mixture of penetrating crystallization coating and cement mortar is applied, an additional layer of waterproof membrane with a width of 200-300mm is laid. Ensure that the newly laid waterproof membrane is well connected and bonded to the existing waterproof layer, especially at the joints, appropriate adhesive materials or welding technology should be used to ensure sealing.

[0107] Adding an extra layer of waterproofing membrane can provide double protection, especially in areas with complex structures or prone to pressure concentration. The additional width of 200-300mm is enough to cover the edge of the original waterproofing layer, reducing the risk of leakage in joints and overlapping areas.

[0108] By using penetrating crystalline paint and cement mortar to strengthen the treatment and additional waterproofing membrane in the detailed locations, potential leakage points in these high-risk areas are effectively sealed. The additional waterproof layer can withstand more environmental stresses, such as temperature changes, physical wear, etc., extending the service life of the waterproofing system. This comprehensive waterproofing strategy ensures the consistency and continuity of the waterproofing system throughout the building structure, reducing the overall maintenance and repair costs.

[0109] In a preferred embodiment of the present invention, the initial curing step comprises:

[0110] S71. Keep the surface moist:

[0111] After the construction is completed, keep the surface of the waterproof layer moist by using a fine mist spraying device or covering with a wet cloth. This operation needs to avoid using too much water flow to avoid washing away the newly constructed waterproof layer. Special attention should be paid to not allowing water to accumulate in any area to prevent premature or uneven hardening of the penetrating crystallization coating and cement mortar layer.

[0112] S72. Initial maintenance time control:

[0113] The curing time is usually set at 24-48 hours, which is enough time for the chemical reaction between the penetrating crystallization coating and the cement mortar to be completely carried out, and the waterproof layer can achieve initial curing. During this period, it is necessary to regularly check the moisture status of the waterproof layer and adjust the moisture retention method appropriately according to weather conditions.

[0114] The effect of penetrating crystallization coating depends in part on its reaction with water in cement mortar to form insoluble crystals that fill the pores. Keeping the surface of the waterproof layer moist helps this chemical reaction proceed. Proper maintenance can prevent cracks in the waterproof layer due to rapid drying and improve the overall strength and durability of the final waterproof layer.

[0115] Adequate initial curing ensures that the chemical reaction within the waterproofing layer is fully carried out, enhancing the structural integrity and waterproofing performance of the material. By keeping the surface moist, shrinkage and cracking problems caused by rapid water evaporation are reduced, thereby reducing the need for future maintenance and repairs.
