Abstract
Description
Technical Field
[0001] The invention relates to the technical field of auxiliary equipment for repairing and reinforcing building surfaces, and in particular to a structural protection coiled material and a manufacturing method thereof. Background Art
[0002] Every year, a large number of roads, bridges, tunnels, sluices, underground pipe wells, ports and other buildings face surface peeling and reduced strength due to long service life and invasion of the natural environment, and thus face repair and reinforcement projects. The traditional method is generally to apply protective coatings on the structure multiple times.
[0003] In this kind of repair and reinforcement project, three layers of paint are generally required, such as one coat of primer, two coats of midcoat, and one coat of topcoat, which takes at least 5 days to complete. In addition, outdoor painting is easily affected by the weather. Sometimes the painting work cannot be carried out on time, and the paint cannot be fully dried, so the construction period is extended, resulting in increased construction costs. In addition, the painting quality is affected by the construction site environment (such as humidity, temperature) and film thickness, base surface roughness, water content, etc., and it is difficult to become stable. Therefore, professional operators are required to paint to improve the quality. Summary of the invention
[0004] The present invention relates to a structural protection coiled material and a manufacturing method thereof, and in particular to a coiled material which can effectively shorten the construction time of a structural protection layer and can protect the structure for a long time.
[0005] The technical solution of the present invention is achieved through the following solution: a structural protection coiled material, comprising a structural protection coiled material and a protective film, wherein the protective film is adhered to the surface of the structural protection coiled material; The structural protection coiled material comprises a polymer cement layer and a resin layer. The resin layer is laid on one side of the polymer cement layer, and the other side of the polymer cement layer is connected to a protective film through an adhesive.
[0006] Through the above technical scheme, the coating of the polymer cement layer and the resin layer is integrated to form a structural protection coil with stable performance. The polymer cement layer, as the main structural part of the coil, provides good durability and has strong toughness and stretchability. The addition of the resin layer for outer protection further enhances the corrosion resistance, weather resistance and chemical corrosion resistance of the coil, so that the coil can maintain stable performance even in harsh environments. The polymer cement layer can be easily compatible with the existing structural surface that needs to be maintained (such as concrete), so that it fits tightly with the existing structural surface, which not only ensures the close fit between the coil and the structure for protection, but also the structural protection coil can follow the changes of the structural surface even when cracks or expansion occurs in the structure.
[0007] Preferably, the polymer cement layer is made by mixing cement, silicon dioxide, aluminum oxide, titanium oxide, water, acrylic resin and acrylic emulsion; The resin layer is prepared by mixing acrylic rubber copolymer emulsion, acrylic silicone resin, titanium dioxide, iron oxide and carbon black. A method for manufacturing a structural protection coiled material comprises the following steps; S1, the mold release sheet is made in the factory and the structural protection coil is made; S2, preparing a composition for forming a polymer cement layer; S3, coating the composition onto a release sheet and drying the composition to form a polymer cement layer; S4, coating the polymer cement layer with a resin composition and drying the composition to form a resin layer; S5, the polymer cement layer and the resin layer are combined to form a structural protection roll material, and demoulding is performed; S6, adhere the protective film and wind it into a roll; S7, repeat S2 to S6, and continue production in the factory.
[0008] Preferably, in step S1, the release sheet is made of polypropylene laminated paper with a thickness of ≥130 μm, and the structural protection coil is coated on the release sheet and dried by a continuous coating and drying device in the factory.
[0009] Preferably, in step S2, the composition is an acrylic emulsion containing 45% by mass of cement mixture; The cement mixture contains at least 70±5 parts by mass of cement, 10±5 parts by mass of silicon dioxide, 2±1 parts by mass of aluminum oxide and 1-2 parts by mass of titanium oxide; The acrylic resin is 45±5 parts by mass, and the acrylic emulsion contains at least 53±2 parts by mass of an acrylic polymer obtained by emulsion polymerization of an acrylic ester monomer using an emulsifier, and 43±2 parts by mass of water.
[0010] Preferably, the specific coating steps of step S3 include: S301, stirring the composition into a coating state; S302, coating the composition on a release sheet through a continuous coating and drying device in the factory, and drying to form a polymer cement layer.
[0011] Preferably, the specific coating steps of step S4 include: S401, preparing a resin composition; S402, coating the resin composition on the polymer cement layer through a continuous coating and drying device in the factory.
[0012] Preferably, in step S401, the resin composition is an emulsion composition consisting of an acrylic rubber copolymer emulsion and an acrylic silicone resin; The acrylic rubber copolymer emulsion is an acrylic rubber copolymer prepared by polymerizing an acrylic monomer emulsion and a rubber monomer emulsion using a surfactant; The acrylic rubber copolymer emulsion accounts for 30 to 70% by weight; The acrylic silicone resin contains at least 60 parts by mass of acrylic silicone resin, 25 parts by mass of titanium dioxide, 10 parts by mass of iron oxide, and 5 parts by mass of carbon black. Preferably, the specific steps of step S6 include: S601, apply adhesive on the demoulding side of the structural protection coil; S602, adhesion protection film; S603, rolled into a stick by a factory roller.
[0013] In summary, the present invention has the following beneficial effects: 1. The present invention integrates the coating of the polymer cement layer and the resin layer to form a structural protection coiled material with stable performance. The polymer cement layer, as the main structural part of the coiled material, provides good durability and has strong toughness and stretchability. The addition of the resin layer for outer protection further enhances the corrosion resistance, weather resistance and chemical corrosion resistance of the coiled material, so that the coiled material can maintain stable performance even in harsh environments. The polymer cement layer can be easily compatible with the existing structural surface layer (such as concrete) that needs to be maintained, so that it fits tightly with the existing structural surface layer, which not only ensures the close fit between the coiled material and the structure for protection, but also the structural protection coiled material can follow the changes of the structural surface layer even when cracks or expansion occurs in the structure.
[0014] 2. The protective film can effectively isolate the adhesive part of the roll, prevent air debris and moisture from invading the adhesive part, ensure that the roll maintains the best adhesive state during transportation and storage, and avoid self-adhesion when rolling.
[0015] 3. Acrylic resin and acrylic emulsion have good waterproof properties and are strong and tough. Inorganic materials such as silica, alumina and titanium oxide have good weather resistance and durability. They can resist erosion by wind, sun, rain and other factors in the natural environment and extend the service life of the roll. Mixing with cement can enhance the adhesion with the surface of the existing structure, and cooperate with the subsequent adhesive to perfectly fit the existing structure. The addition of acrylic resin can effectively improve the fusion of the subsequent coating of the resin layer.
[0016] 4. Acrylic rubber copolymer emulsion and acrylic silicone resin have excellent elasticity, which can further give the coil good flexibility, improve the tear strength and wear resistance of the coil, enable it to adapt to the slight deformation of the base layer, and reduce the cracks caused by the deformation of the base layer. Carbon black effectively enhances the weather resistance and anti-aging properties of the coil.
[0017] 5. By adopting the self-adhesive form, while ensuring that the structure is dry and tidy, tear off the protective film of the roll and stick it directly to the surface of the structure, reducing the impact of environmental factors on the construction, saving construction time, improving construction efficiency, and saving labor costs. Since the thickness of the roll is uniform, a structural protective layer with small thickness deviation can be stably and quickly set on the surface of the structure without the need for professional operators.
[0018] 6. Compared with the traditional coating of structural protection sheets, the present invention can be directly pasted on the surface of the structure after the protective film is torn off, eliminating the process of coating the adhesive on the structure, and also avoiding the loose bonding caused by uneven coating of the adhesive or partial omission of the adhesive, thereby reducing labor and construction costs.
[0019] 7. Structural protection rolls can be produced and stored in a relatively stable indoor environment. During construction, the rolls only need to be laid in place. Compared with traditional paint coverings, the laying and adhesion of the rolls are less affected by the weather. Through industrialized production of rolls, the quality and performance of the rolls can be strictly controlled, which not only improves the stability of construction quality, but also reduces the rework and maintenance costs caused by quality problems.

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments.
[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. The present invention is further described in detail below in conjunction with the accompanying drawings.
[0024] Structure refers to prefabricated components, roads and bridges, floors, underground pipes, interior and exterior walls of buildings, wells, storage rooms, etc. made of engineering construction materials such as reinforced concrete, plain concrete, cement mortar, etc.
[0025] Embodiment 1: A structural protection coiled material, such as Figure 1 and Figure 2As shown, it includes a structural protection coiled material 1 and a protective film 5, and the protective film 5 is adhered to the surface of the structural protection coiled material 1; the structural protection coiled material 1 includes a polymer cement layer 2 and a resin layer 3, the resin layer 3 is laid on one side of the polymer cement layer 2, and the protective film 5 is connected to the other side of the polymer cement layer 2 by an adhesive. Due to the presence of cement components, the polymer cement layer 2 is easy for water vapor to pass through the original building structure. At this time, the water vapor permeability is about 10 to 50 g / m²·day, and the cement component has good compatibility with the cement component of the original building structure concrete, which can make it have excellent adhesion to the concrete surface. Since the polymer cement layer 2 is tensile, it can follow the changes of the concrete even when cracks or expansions occur in the structure. The protective film 5 protects the adhesive layer of the structural protection coiled material 1 to ensure that the adhesive layer does not lose its viscosity.
[0026] The polymer cement layer 2 and the resin layer 3 are both formed by multi-layer stacking. Considering the overall thickness, the functions imparted (durability, waterproofness, corrosion resistance, resistance to neutralization reactions, adhesion, water vapor permeability, etc.) and the production cost, the thickness of the polymer cement layer 2 and the resin layer 3 is set to 0.1 to 5 mm according to on-site requirements.
[0027] The resin layer 3 can adhere to the polymer cement layer 2 to prevent cracks or cracks therefrom, and can form excellent waterproofness, corrosion resistance, neutralization resistance and water vapor permeability. The resin layer 3 preferably uses a resin containing an elastic film-forming component. The protective film 5 is a plastic film that can protect the roll material when it is transported to the construction site. At the construction site, the protective film can be peeled off and the roll material can be pasted on the structural surface. The structural protection roll material 1 can be adhered to the existing structure through the adhesive provided by the structure. The protective film 5 can be any one of plastic films such as polyethylene film, polypropylene film, polystyrene (PS) film and polyvinylidene chloride (PVDC) film, and can be replaced based on economic cost. The polymer cement layer 2 has excellent workability and good compatibility.
[0028] The polymer cement layer 2 is made of a mixture of cement, silicon dioxide, aluminum oxide, titanium oxide, water, acrylic resin and acrylic emulsion. The cement can be selected according to the properties that the polymer cement layer 2 should have and the degree of affinity to the existing concrete structure. It is preferably silicate cement. The mixture is stirred into a coating and applied to the mold. The resin layer 3 is made of a mixture of acrylic rubber copolymer emulsion, acrylic silicone resin, titanium dioxide, iron oxide and carbon black to form a mixed coating liquid, which is coated on the polymer cement layer 2 to integrate it into one. Preferably, acrylic silicone resin with rubber properties is used.
[0029] Embodiment 2: A method for manufacturing a structural protection coiled material, such as Figure 1 to Figure 3 As shown, the following steps are included: S1, manufacturing a release sheet 4 and a structural protection coil 1 in a factory; In step S1, the release sheet 4 is made of polypropylene laminated paper with a thickness of ≥130μm. The structural protection coil 1 is coated on the release sheet 4 and dried by a continuous coating and drying device in the factory. The release sheet 4 provides a coating carrier for the structural protection coil 1. The polypropylene laminated paper is a composite material that combines the properties of polypropylene film and paper. It has excellent wear resistance, corrosion resistance, high temperature resistance and good demoulding performance, ensuring that the structural protection coil 1 can remain flat and stable during the curing process.
[0030] S2, preparing a composition for forming a polymer cement layer 2; In step S2, the composition is an acrylic emulsion containing 45% by mass cement mixture; The cement mixture contains at least 70±5 parts by mass of cement, 10±5 parts by mass of silicon dioxide, 2±1 parts by mass of aluminum oxide and 1-2 parts by mass of titanium oxide; the cement is preferably silicate cement, which provides the necessary strength and durability for the main component of the polymer cement layer 2. The addition of silicon dioxide helps to improve the physical properties of the cement mixture, improve its impermeability and wear resistance, and aluminum oxide can further enhance the chemical stability and thermal stability of the cement mixture. Its titanium oxide not only has excellent whiteness and hiding power, but also can improve the weather resistance and UV resistance of the cement mixture.
[0031] Acrylic resin 45±5 parts by mass, acrylic emulsion contains at least 53±2 parts by mass of acrylic polymer formed by emulsion polymerization of acrylate monomer using an emulsifier and 43±2 parts by mass of water. The actual proportion of acrylic emulsion needs to be adjusted according to the total mass to ensure that the cement mixture accounts for 45% by mass, dilutes the cement mixture and provides the required flexibility and adhesion. The emulsion helps the dispersion and coating of the polymer and evaporates during the drying process to form a tough polymer cement layer 2. When the acrylic resin is mixed and coated, it can interact with the cement mixture to form a strong bond, forming a whole, and improving the fusion of the subsequent coating of the resin layer 3.
[0032] S3, coating the composition onto a release sheet 4 and drying the composition to form a polymer cement layer 2; S301, stirring the composition into a coating state; S302, coating the composition on the release sheet 4 through a continuous coating and drying device in the factory, and drying to form a polymer cement layer 2.
[0033] The cement mixture and acrylic emulsion are fully mixed to form a coating-like substance that is easy to apply. During the stirring process, it is necessary to ensure that each component is fully dispersed and evenly mixed to avoid agglomeration or stratification. The stirring time should be adjusted according to the actual situation until a uniform and fine coating-like substance is formed. The polymer cement layer 2 is applied and dried layer by layer through a continuous coating and drying device until the required thickness of the project is reached.
[0034] S4, coating the resin composition on the polymer cement layer 2 and drying it to form a resin layer 3; S401, preparing a resin composition; In step S401, the resin composition is composed of an acrylic rubber copolymer latex and an acrylic silicone resin to form an emulsion composition; The acrylic rubber copolymer emulsion is an acrylic rubber copolymer prepared by polymerizing an acrylic monomer emulsion and a rubber monomer emulsion using a surfactant; The acrylic rubber copolymer emulsion accounts for 30 to 70% by weight; The acrylic silicone resin contains at least 60 parts by mass of acrylic silicone resin, 25 parts by mass of titanium dioxide, 10 parts by mass of iron oxide, and 5 parts by mass of carbon black.
[0035] As the surfactant, any of anionic, nonionic and cationic surfactants can be used.
[0036] S402, coating the resin composition on the polymer cement layer 2 through a continuous coating and drying device in the factory; The thickness of the resin layer 3 is consistent with the process of the polymer cement layer 2, and is also applied and dried layer by layer until the required thickness of the project is reached. After coating, the resin layer 3 has flexibility and can adapt to and adhere to the polymer cement layer 2, and further enhance the service life of the polymer cement layer 2.
[0037] S5, the polymer cement layer 2 and the resin layer 3 are combined to form a structural protection coiled material 1, and demoulding is performed; After drying, the resin layer 3 is integrated with the polymer cement layer 2 . The combined thickness of the resin layer 3 and the polymer cement layer 2 is ≤5 mm. If the thickness is greater than 5 mm, the air permeability is reduced, which affects the performance and service life of the structural protection coiled material 1 .
[0038] S6, adhering the protective film 5 and winding it into a roll; S601, applying adhesive to the demoulding side of the structural protection coiled material 1; S602, adhesion protection film 5; S603, rolled into a stick by a factory roller.
[0039] S7, repeat S2 to S6, and continue production in the factory.
[0040] The structural protection coil 1 can reduce the thickness distribution deviation and realize mass production through coating and drying processes on the factory production line, thereby achieving low cost, significant reduction in on-site operation time, and long-term protection of the structure. The structural protection coil is continuously produced in the factory and is wound into a roll in a manner including a protective film 5. After the coil is produced in the factory, it is transported to the structural construction site. After the surface base of the structure is cleaned, the protective film 5 of the coil is torn off, and the adhesive of the coil is used to manually stick the coil to the surface of the structure to complete the surface protection construction of the structure. The protective film 5 can effectively protect the viscosity and prevent the coil from sticking to itself when rolling.
