Description

Technical Field

[0001] This utility model relates to the field of coating technology for waterproof materials, and more specifically, to a coating system. Background Technology

[0002] Elastomer-modified bitumen waterproof membrane is a new type of waterproof material that uses polymer elastomers to modify bitumen. This type of waterproof membrane combines the durability of bitumen with the flexibility of polymers, making it widely applicable in waterproofing projects. Elastomer-modified bitumen waterproof membrane is made with polyester felt, fiberglass felt, or fiberglass-reinforced polyester felt as the base material, styrene-butadiene-styrene (SBS) thermoplastic elastomer as the petroleum bitumen modifier, and both sides covered with a release liner.

[0003] Currently, the main production process of elastomeric modified bitumen waterproof membrane is to first pre-impregnate the base material, and then coat the base material with a modified bitumen coating layer to improve the adhesion between the base material and the modified bitumen coating layer, thus giving the membrane both adhesion and waterproofing properties.

[0004] Applying a modified bitumen coating layer to the base material is called "oiling" in the waterproof membrane production industry. Because the base material still contains a small amount of air and moisture after pre-impregnation and squeezing, and the bitumen itself will evaporate oil at high temperatures, the air in the base material expands when heated, the moisture evaporates, and the light components of the bitumen evaporate. This can easily cause pores to appear in the coating layer after the modified bitumen coating layer is applied, resulting in poor membrane density, reduced waterproof performance, and in severe cases, water seepage points, causing the membrane to lose its waterproof effect. Utility Model Content

[0005] One objective of this invention is to provide a new technical solution for a coating system, which can at least solve problems such as poor compactness of roll materials and reduced waterproof performance of roll materials in the prior art.

[0010] Optionally, the hot air device includes: an air knife disposed above the tire base; and a hot air blower connected to the air knife to blow hot air onto the tire base through the air knife.

[0011] Optionally, the temperature of the hot air generated by the hot blower is 300-350℃, and the air velocity provided by the air knife is 2-4m / s.

[0012] Optionally, the oiling device is an oiling nozzle, and there are three oiling devices. The three oiling devices are spaced apart in the conduction direction of the tire base.

[0015] This invention discloses a coating system that employs multiple coating applications, improving the penetration of the coating layer into the tire substrate and enhancing the adhesion between the coating layer and the tire substrate.

[0033] The coating system according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] like Figure 1 As shown, the coating system according to an embodiment of the present invention includes a thickness roller 10, an oiling device 20, a negative pressure device 30, and a hot air blowing device 40.

[0035] Specifically, the thickness roller 10 is used to conduct the coating onto the tire base 52. Multiple oiling devices 20 are sequentially spaced apart along the conduction direction of the tire base 52 to apply multiple coats to it. A negative pressure device 30 is used to apply negative pressure to the tire base 52 after the first coat. A hot air device 40 is used to apply hot air to the tire base 52 after the second coat.

[0036] In other words, such as Figure 1As shown, the coating system according to this embodiment of the present invention is mainly used to improve the density of waterproof membranes (e.g., base material 52), reduce the permeability of the membrane, improve the waterproof performance of the membrane, extend the service life of the waterproof membrane in actual application, and enhance the waterproof effect of the waterproof membrane. The coating system according to this embodiment of the present invention mainly consists of a thickness roller 10, an oiling device 20, a negative pressure device 30, and a hot air blowing device 40. The thickness roller 10 is used to conduct the base material 52, which is conducted through the thickness roller 10. Multiple oiling devices 20 are installed in the conduction direction of the base material 52 and are distributed sequentially at intervals to achieve multiple coatings on the base material 52. By adopting a multiple coating method, the permeability of the coating layer to the base material 52 is improved, and the adhesion between the coating layer and the base material 52 is enhanced.

[0037] like Figure 1 As shown, the negative pressure device 30 is mainly used to perform negative pressure treatment on the base material 52 after the first coating. The negative pressure adsorption method of the negative pressure device 30 improves the compactness of the roll material. Since the base material 52 needs to be squeezed dry after pre-impregnation, the squeezed base material 52 has a certain degree of air permeability. After the first coating, by installing the negative pressure device 30 on both sides of the base material 52, the air and moisture in the base material 52 are promoted to be discharged. In addition, the negative pressure acting on the surface of the coating layer also improves the permeability of the coating layer to the base material 52 and improves the adhesion performance between the coating layer and the base material 52.

[0038] The hot air blower 40 is used to treat the base material 52 after the second coating with hot air. By using the hot air blower 40 to exhaust air, the density of the roll material is improved. After the second coating, hot air at a temperature much higher than the coating temperature acts on the surface of the roll material. Due to the rapid temperature rise, the thinner coating layer with poor density will be quickly destroyed, forming holes. This makes it easier for the coating material to fill the holes during the third coating, thereby improving its density.

[0039] Therefore, the coating system according to this embodiment of the present invention employs a multi-coating method, which improves the permeability of the coating layer to the base material 52 and enhances the adhesion between the coating layer and the base material 52. The negative pressure device 30 promotes the removal of air and moisture from the base material 52, further improving the permeability of the coating layer and the adhesion between the coating layer and the base material 52. The hot air device 40 rapidly breaks down the thinner, less dense coating layer, creating pores that facilitate subsequent filling with coating material during oiling, thus improving its density.

[0040] According to one embodiment of the present invention, the negative pressure device 30 includes a negative pressure box 31, an adsorption rack 32, and a negative pressure motor 33.

[0041] Specifically, the negative pressure chamber 31 is used to accommodate the conductive tire base 52. Adsorption racks 32 are disposed within the negative pressure chamber 31, and are located on opposite sides of the tire base 52. A negative pressure motor 33 is connected to the adsorption racks 32 to create a negative pressure within the negative pressure chamber 31.

[0042] In other words, such as Figure 1 As shown, the negative pressure device 30 mainly consists of a negative pressure chamber 31, an adsorption rack 32, and a negative pressure motor 33. The negative pressure chamber 31 houses the conductive tire base 52. The tire base 52 is subjected to negative pressure within the chamber 31, expelling air and moisture. This negative pressure also acts on the surface of the coating layer, improving the permeability of the coating layer to the tire base 52, enhancing adhesion, and reducing the presence of pores. The adsorption racks 32 are installed within the negative pressure chamber 31, positioned on opposite sides of the tire base 52. Each adsorption rack 32 is connected to a negative pressure motor 33, thereby creating negative pressure within the chamber 31.

[0043] In some specific embodiments of this utility model, such as Figure 1 As shown, the length of the adsorption rack 32 can be greater than 50mm, allowing the roll material to undergo negative pressure degassing for a longer period. The distance between the two opposing adsorption plates on the adsorption rack 32 can be 5-8cm, and the distance between the adsorption plates and the base material 52 is 1-5cm, achieving negative pressure treatment of the base material 52. The negative pressure adsorption method of the negative pressure device 30 improves the compactness of the roll material. Since the base material 52 needs to be squeezed dry after pre-impregnation, the squeezed base material 52 has a certain degree of air permeability. After the first oiling, by installing the negative pressure device 30 on both sides of the base material 52, air and moisture in the base material 52 are promoted to be expelled. Furthermore, the negative pressure acting on the surface of the coating layer also improves the permeability of the coating layer to the base material 52, thus improving the adhesion between the coating layer and the base material 52. Of course, the length of the adsorption rack 32, the distance between the adsorption plates, and the distance between the adsorption plates and the base material 52 can be specifically set according to actual needs, and will not be described in detail in this utility model.

[0044] In some specific embodiments of this utility model, the negative pressure generated by the negative pressure motor 33 can be 0.02-0.05 MPa, the cross-sectional width of the negative pressure box 31 is greater than the cross-sectional width of the base material 52, and the height of the negative pressure box 31 can be 10-20 cm, thus achieving effective treatment of the base material 52. The negative pressure adsorption method of the negative pressure device 30 improves the compactness of the roll material. Since the base material 52 needs to be squeezed dry after pre-impregnation, the squeezed base material 52 has a certain degree of air permeability. After the first oiling, by installing the negative pressure device 30 on both sides of the base material 52, the air and moisture in the base material 52 are promoted to be discharged. Furthermore, the negative pressure acting on the surface of the coating layer also improves the permeability of the coating layer to the base material 52 and improves the adhesion performance between the coating layer and the base material 52. Of course, the negative pressure value of the negative pressure motor 33 and the height of the negative pressure box 31 can be specifically set according to actual needs, and will not be described in detail in this utility model.

[0045] According to one embodiment of the present invention, the hot air device 40 includes an air knife 41 and a hot air blower 42.

[0046] Specifically, the air knife 41 is positioned above the tire base 52. A hot air blower 42 is connected to the air knife 41 to blow hot air onto the tire base 52 through the air knife 41.

[0047] In other words, such as Figure 1 As shown, the hot air blowing device 40 mainly consists of an air knife 41 and a hot air blower 42. The air knife 41 is installed above the tire base 52. The air knife 41 can blow hot air onto the tire base 52 (see [reference needed] for the direction of hot air blowing). Figure 1 (In the direction of the middle arrow). The hot blower 42 is connected to the air knife 41, and the hot blower 42 provides hot air to the air knife 41. After the base material 52 is treated by the negative pressure device 30, it is coated a second time using the oiling device 20 to complete the coating process of the second coating layer. This results in the presence of the second coating layer on the surface. The coating layer is then sheared and compressed by the thickness roller 10 to control its thickness, and then the surface pores are destroyed by the hot blower device 40, which consists of the hot blower 42 and the air knife 41. By applying hot air at a temperature much higher than the oiling temperature to the surface of the roll material, the thinner coating layer with poor density will be quickly destroyed due to the rapid temperature rise, forming pores. This allows the coating material to fill the pores during the third oiling process, improving its density.

[0048] In some specific embodiments of this utility model, the temperature of the hot air generated by the hot blower 42 can be 300-350℃, and the air velocity provided by the air knife 41 can be 2-4m / s, achieving efficient hot air treatment of the base material 52. By applying hot air at a temperature much higher than the oiling temperature to the surface of the roll material, the thinner coating layer with poor density will be rapidly destroyed due to the rapid temperature rise, forming pores. This facilitates the filling of the pores with coating material during the third oiling, improving its density.

[0049] According to one embodiment of the present invention, the oiling device 20 is an oiling nozzle, and there are three oiling devices 20. The three oiling devices 20 are spaced apart in the conduction direction of the tire base 52. In the conduction direction of the tire base 52, a negative pressure device 30 and a hot air blower 40 are sequentially provided between two adjacent oiling devices 20.

[0050] In other words, such as Figure 1 As shown, the oiling device 20 can be an oiling nozzle, and there can be three oiling devices 20, which can be spaced apart in the conduction direction of the base 52. In the conduction direction of the base 52, a negative pressure device 30 and a hot air blower 40 are sequentially arranged between two adjacent oiling devices 20. Through the three-stage coating process, the waterproof membrane coating layer has a shearing and defoaming effect. Multiple compressions drive away air bubbles generated during production, and the compression process improves the permeability of the coating layer to the base 52, thus improving the adhesion between the coating layer and the base 52. Of course, the specific number of oiling devices 20 can be set according to actual needs, and will not be described in detail in this utility model.

[0051] According to one embodiment of the present invention, such as Figure 1 As shown, the oiling device 20 applies oil multiple times to the base 52, forming a first coating layer 51, a second coating layer, and a third coating layer 53 on the base 52. The first coating layer 51 is the coating layer for the first construction surface, and the third coating layer 53 is the coating layer for the water-facing surface. After pre-impregnation and desqueezing, the base 52 undergoes its first oiling process via the oiling device 20, completing the initial coating layer application. This leaves the surface with the first coating layer. The coating layer is then sheared and compressed by the thickness roller 10 to control its thickness. Next, a negative pressure adsorption process is performed by a negative pressure device 30, consisting of a negative pressure motor 33, an adsorption frame 32, and a negative pressure box 31. By installing the negative pressure devices 30 on both sides of the base 52, air and moisture are expelled from the base 52. The negative pressure acting on the surface of the coating layer also improves the permeability of the coating layer to the base 52, enhances the adhesion between the coating layer and the base 52, and reduces the presence of pores. After being processed by the negative pressure device 30, the second oiling device 20 applies a second layer of oil to the tire base 52, completing the coating process of the second coating layer. This results in the presence of the second coating layer on the surface, which is then sheared, squeezed, and its thickness controlled by the thickness roller 10.

[0052] like Figure 1As shown, the surface pores are then broken by a hot air device 40 consisting of a hot blower 42 and an air knife 41. Hot air, at a temperature much higher than the coating temperature, acts on the surface of the roll material. Due to the rapid temperature increase, the thinner coating layer with poor density is quickly broken down, forming pores. This allows the coating material to fill the pores during the third coating, improving its density. After treatment by the hot air device 40, the third coating device 20 applies the final coating layer, leaving the surface with the third coating. The coating layer is then sheared and compressed by a thickness roller 10 to control its thickness. Finally, it is cooled and covered with a release material to obtain a complete roll material. This three-stage coating process has a shearing and defoaming effect on the waterproof roll material coating layer. Multiple compressions drive away air bubbles generated during production, and the compression process also improves the permeability of the coating layer to the base material 52, thus enhancing the adhesion between the coating layer and the base material 52.

[0053] According to one embodiment of the present invention, the thickness of the base 52 is 3-5mm, and the coating thicknesses of the first coating layer 51, the second coating layer and the third coating layer 53 are 10%-50% of the thickness of the base 52, respectively.

[0054] Specifically, the coating device 20 is suitable for the production of reinforced waterproof membranes with a thickness of 3 / 4 / 5mm. For 3mm thick waterproof membranes, the first coating thickness is 40-50% of the cover layer thickness, the second coating thickness is 30-40%, and the third coating thickness is 10-30%. For 4mm thick waterproof membranes, the first coating thickness is 30-40%, the second coating thickness is 40-50%, and the third coating thickness is 10-30%. For 5mm thick waterproof membranes, the first coating thickness is 20-30%, the second coating thickness is 50-60%, and the third coating thickness is 10-30%. By applying the coating material three times, the coating material layer of the waterproof membrane has a shearing and defoaming effect. The multiple extrusions drive away the air bubbles generated during the production process, and the extrusion process also improves the permeability of the coating material layer to the base material 52, thus improving the adhesion between the coating material layer and the base material 52.

[0055] In this invention, the coatings used in the three coats can be coatings with different properties. Specifically, the first coating layer can be a coating layer with strong adhesion and low viscosity, facilitating adhesion to the base layer 52 and the adsorption effect of the negative pressure device 30. The second coating layer can be a coating layer with high viscosity, high strength, and better heat resistance, improving the strength and flexibility of the waterproof membrane. It can withstand the action of hot air without affecting the performance of the waterproof membrane. The third coating layer can be a coating layer with low viscosity and good oil exudation. Its high fluidity and low viscosity allow it to effectively penetrate into the pores created by the hot air exhaust method, improving the density of the waterproof membrane and the subsequent construction performance. Of course, the specific coatings can be selected according to actual needs, which will not be described in detail in this invention.

[0056] In summary, the coating system according to this embodiment of the present invention employs a multi-coat application method, which improves the permeability of the coating layer to the base material 52 and enhances the adhesion between the coating layer and the base material 52. The negative pressure device 30 promotes the removal of air and moisture from the base material 52, further improving the permeability of the coating layer and the adhesion between the coating layer and the base material 52. The hot air device 40 rapidly breaks down the thinner, less dense coating layer, creating pores that facilitate subsequent filling with coating material during oiling, thus improving its density.

[0057] Of course, those skilled in the art will understand and be able to implement other structures and working principles of the coating system, which will not be described in detail in this utility model.

[0058] According to a second aspect of the present invention, a method for applying a coating material is provided, wherein the coating material application system described in the above embodiments is used for coating treatment, and the coating material application method includes:

[0059] S1. Place the tire base 52 on the thickness roller 10 so that the tire base 52 can be conducted relative to the thickness roller 10;

[0060] S2. Apply the first oil to the tire base 52 using the oiling device 20;

[0061] S3. After the first oiling, the tire base 52 is transmitted to the negative pressure device 30 for negative pressure treatment;

[0062] S4. After the negative pressure treatment is completed, the negative pressure device 30 is discharged and a second oiling is performed;

[0063] S5. After the second oiling, the tire base 52 is transferred to the hot air device 40 for hot air treatment.

[0064] S6. After the hot air treatment is completed, apply the third coat of oil.

[0065] S7. Complete the above steps at least once to obtain the oiled tire base 52.

[0066] In other words, such as Figure 1 As shown, according to the coating method of this utility model, the coating system described in the above embodiment is used for coating treatment. In the coating method of this utility model, firstly, the base material 52 can be placed on the thickness roller 10 so that the base material 52 can be conductive relative to the thickness roller 10. Then, the base material 52 is coated with oil for the first time by the oiling device 20. After the base material 52 has undergone the pre-impregnation and desqueezing process, it undergoes the first oiling process by the oiling device 20, completing the coating process of the first coating layer, so that the surface has the coating material after the first coating. The coating layer is then sheared and compressed and the thickness is controlled by the thickness roller 10.

[0067] After the first coat of oil is applied, the base 52 is transferred to the negative pressure device 30 for negative pressure treatment. By installing the negative pressure device 30 on both sides of the base 52, air and moisture in the base 52 are expelled, and the negative pressure acts on the surface of the coating layer, which also improves the permeability of the coating layer to the base 52, improves the adhesion between the coating layer and the base 52, and reduces the presence of pores.

[0068] After the negative pressure treatment is completed, the negative pressure device 30 is discharged, and a second oiling is performed. This completes the second coating layer process, leaving the surface with the second coating material. The coating material is then sheared and compressed by the thickness-fixing roller 10 to control its thickness. The tire base 52, after the second oiling, is transferred to the hot air device 40 for hot air treatment. After treatment by the hot air device 40, it passes through the third oiling device 20 for a third oiling, completing the final coating layer process. This leaves the surface with the third coating material, which is then sheared and compressed by the thickness-fixing roller 10 to control its thickness.

[0069] After the hot air treatment, a third coat of oil is applied. Finally, the membrane is cooled and covered with a release material to obtain a complete roll. This invention can use multiple oiling devices 20 to complete the above steps at least once, resulting in an oiled base 52. The three-coat application method achieves a shearing and defoaming effect on the waterproof membrane coating layer, repeatedly expelling air bubbles generated during production, and improving the permeability of the coating layer to the base 52 through extrusion, thus enhancing the adhesion between the coating layer and the base 52.

[0070] In summary, the coating method according to this embodiment of the present invention employs multiple coating applications, which improves the permeability of the coating layer to the tire base 52 and enhances the adhesion between the coating layer and the tire base 52. The negative pressure device 30 promotes the removal of air and moisture from the tire base 52, further improving the permeability of the coating layer to the tire base 52 and enhancing the adhesion between the coating layer and the tire base 52. The hot air device 40 rapidly breaks down the thinner, less dense coating layer, creating pores that facilitate subsequent filling with coating material during oiling, thus improving its density.
