Description

Technical Field

[0001] The invention belongs to the technical field of waterproof materials, and particularly relates to a non-bituminous root-resistant glue, a structure of a non-bituminous root-penetration resistant waterproof coil and a preparation method thereof. Background Art

[0002] With the update of the "General Code for Waterproofing of Buildings and Municipal Engineering" and various codes, new requirements are put forward for the durability of waterproof materials, emphasizing that the waterproof materials should have the same service life as the building. Among waterproof materials, bituminous materials are used as traditional main waterproof materials due to their excellent workability. However, the aging attenuation of bituminous materials is also a major drawback. The main components of bituminous materials are aromatic hydrocarbon components, naphthene hydrocarbon components, resins, and asphaltenes. It is found through research that resins will be transformed into asphaltenes during the aging process, making the material harden, its elasticity decrease, and its mechanical properties significantly decline. Moreover, with the expansion of the market for rooftop greening of buildings, there is a need for waterproof materials laid on rooftops to have root-penetration resistance to ensure the waterproof effect of the waterproof materials. At the same time, since there is no concrete protective layer above the waterproof materials for planted rooftops, thermo-oxidative aging is more serious, posing a high requirement for the aging resistance of the materials. However, most of the existing root-penetration resistant coils on the market are bituminous-based materials, and it is inevitable that the waterproof materials will age over time. Therefore, in combination with the requirements of durability and root-penetration resistance, it is particularly important to develop a non-bituminous root-penetration resistant waterproof coil. Summary of the Invention

[0003] In view of this, the present application provides a non-bituminous root-resistant glue, a structure of a non-bituminous root-penetration resistant waterproof coil and a preparation method thereof. In the rubber compound formula of the non-bituminous root-resistant glue, a root inhibitor is introduced to ensure that the material has a strong root inhibition effect. High-viscosity aromatic oil and low-viscosity aromatic oil are also selected as the main raw materials, and SBS is used in combination with SIS to construct a macromolecular skeleton, providing sufficient mechanical strength for the material, thereby improving the durability and safety of the waterproof material. In the structure of the non-bituminous root-penetration resistant waterproof coil, a combination of physical root inhibition and chemical root inhibition is adopted. Among them, for physical root inhibition, a copper tire base with more than one layer is designed, making the mechanical strength of the material higher. For chemical root inhibition, the above-mentioned non-bituminous root-resistant glue is used, and a root inhibitor is introduced into the rubber compound formula to ensure that the material has a strong root inhibition effect, greatly improving the overall durability and safety of the waterproof material, and thus ensuring the integrity of the planted rooftop structure.

[0038] (3) After preheating the non-bituminous root-resistant rubber compound to 165 - 175 °C, evenly coat it on the upper and lower surfaces of the copper tire base, and then adjust the thickness of the non-bituminous root-resistant rubber compound coated on the upper and lower surfaces of the copper tire base by rolling with a thickness-adjusting roller;

[0039] (4) Use the upper and lower pairs of traction rollers to respectively traction the PE film and the anti-aging PE isolation film to adhere to the upper and lower side surfaces of the non-bituminous root-resistant rubber compound coated on the upper and lower surfaces of the copper tire base and roll to form the waterproof coiled material;

[0040] (5) Send the waterproof coiled material with double-sided film covering into the water bed cooling system for cooling, and the water temperature of the cooling water is 30 - 35 °C.

[0041] 2. When the copper tire base layer is two layers, the preparation method includes the following steps:

[0042] (1) Dry the copper tire base, and the drying temperature is 160 - 170 °C;

[0043] (2) After heating the pre-impregnating oil to 195 - 205 °C, perform pre-impregnating treatment on the dried copper tire base with the pre-impregnating oil, and then remove the residual pre-impregnating oil on the surface of the copper tire base; the pre-impregnating oil is mainly composed of high-viscosity aromatic oil, low-viscosity aromatic oil, and styrene-butadiene-styrene copolymer mixed in a mass ratio of 40 - 50 parts : 40 - 50 parts : 5 - 10 parts, where the high-viscosity aromatic oil refers to an aromatic oil with a viscosity of 3000 - 12000 mPa·s, and the low-viscosity aromatic oil has a viscosity of 200 - 3000 mPa·s;

[0044] (3) After preheating the non-bituminous root-resistant rubber compound to 165 - 175 °C, evenly coat it on the upper and lower surfaces of the copper tire base, and then adjust the thickness of the non-bituminous root-resistant rubber compound coated on the upper and lower surfaces of the copper tire base by rolling with a thickness-adjusting roller;

[0045] (4) Use the upper and lower pairs of traction rollers to respectively traction another layer of copper tire base and a layer of film to adhere to the upper and lower side surfaces of the non-bituminous root-resistant rubber compound coated on the upper and lower surfaces of the copper tire base; the layer of film is one of the PE film and the anti-aging PE isolation film, and the other layer of copper tire base is first dried in step (1) and then pre-impregnated with the pre-impregnating oil in step (2) before adhesion;

[0046] (5) Then, after coating the upper surface of another copper tire base with a non-bituminous root-resistant rubber compound preheated to 165 - 175°C, another layer of film is laminated on the upper surface of the coated non-bituminous root-resistant rubber compound and rolled to form a waterproof coiled material; or, while laminating another layer of film on the upper surface of another copper tire base, the non-bituminous root-resistant rubber compound preheated to 165 - 175°C is injected into the gap between the upper surface of another copper tire base and another layer of film, and rolled to form a waterproof coiled material; the other layer of film is the other one of a PE film and an anti-aging PE isolation film;

[0048] In the present invention, high-viscosity aromatic oil and low-viscosity aromatic oil are selected as the main raw materials in the rubber compound formula. SBS is used in combination with SIS to construct a macromolecular framework, providing sufficient mechanical strength for the material. Since SIS is rich in unsaturated double bonds, it can provide a certain flexible space within the macromolecular framework. Subsequently, styrene-butadiene rubber is added to increase the density of the material's spatial structure. At the same time, due to the good viscoelasticity of styrene-butadiene rubber, it fills the role of asphalt colloid substances. Using this rubber compound as the coated rubber compound in the coiled material structure can improve the peeling effect of the material, making it more convenient for construction. Moreover, the small molecular components of the material are reduced, the structure density is greater, the aging migration is smaller, and the durability of the material is stronger. A root inhibitor is also introduced in the formula to ensure that the material has a strong root resistance effect; in the coiled material structure, a design of more than one layer of copper tire base is introduced, the mechanical strength of the material is higher, the ability to resist deformation is stronger, and the service life of the material is indirectly improved. The high-density copper foil is a dense physical barrier. When plant roots approach, it will slowly release copper ions, interfering with the permeability of the plant root cell membrane, inhibiting the activity of the plant root meristem, hindering cell division, and causing the roots to turn or stop growing; in the preparation method, pre-impregnated oil and multiple coatings of rubber compound are used, the compactness of the material is higher, the generation of bubbles is reduced, and from a microscopic perspective, the continuous phase of the material is compact, less damaged during the aging process, and the performance attenuation is lower. The waterproof coiled material structure of the present invention has excellent performance in terms of durability, root penetration resistance, and economy. Therefore, this type of waterproof coiled material has a very broad application prospect. Description of the Drawings

Due to the relatively low density and large oil absorption of light calcium powder, the material viscosity will be relatively thick. Therefore, the filler is preferably silica powder.

[0068] (2) The preparation method of the non-bituminous root-resistant rubber compound of the present invention is implemented as follows:

[0069] It includes the following steps:

[0075] (III) The implementation method of the non-asphalt-based root-resistant rubber waterproofing membrane structure of the present invention is as follows:

[0076] The non-asphalt-based root-resistant rubber waterproofing coiled material structure of the present invention comprises a PE film 7, one or more layers of a copper base 2, and an anti-aging PE isolation film 10. Figure 1 The structure diagram of the waterproof coiled material when a single-layer copper base is used is shown, wherein the top layer is a PE film 7 which is a water-facing layer, and ordinary PE type film materials are used. During the production process, the appearance is required to be smooth and easy to tear. The bottom layer is an anti-aging PE isolation film 8, which is a special coating treatment on the surface of the base PE film material to make the material more compact and form a good isolation layer with the surface of the material, further slowing down the viscosity attenuation caused by long-term storage or thermal oxygen erosion. The preferred Upers F901 anti-aging PE isolation film layer has a thickness of 0.035-0.045mm, a unit area mass of 35-45g / ㎡, and a width of 1055-1065mm. During the production process, the appearance is required to be smooth and free of holes.

The copper base is a copper foil, preferably a Xinrui sandwich copper foil, and its maximum tensile force should be not less than 800N and the moisture content should be not more than 2%. The elongation is not less than 40%, the mass per unit area is 70-90g / ㎡, the thickness is 1.2-1.6mm, and the width is 1005-1015mm; the non-asphalt-based root-resistant rubber material described in embodiment 1 prepared in embodiment 2 of the present invention is applied between the copper base 2 and the PE film 7, and between the copper base 2 and the anti-aging PE isolation film 8 to form a non-asphalt-based root-resistant rubber material layer 10.

[0077] like Figure 2 The figure shows the structure of the waterproof membrane when a double-layer copper base is used. Figure 1 The difference between the single-layer copper base is that a double-layer copper base 2 is arranged between the top PE film 7 and the bottom anti-aging PE isolation film 8, and the non-asphalt-based root-resistant rubber material described in embodiment 1 prepared in embodiment 2 of the present invention is applied between each layer to form a non-asphalt-based root-resistant rubber material layer 10.

After preheating the non-bituminous root-resistant rubber compound to 165 - 175 °C, it is evenly coated on the upper and lower surfaces of the copper matrix 2 through the upper oil coating roller 4 and the lower oil coating roller 3 respectively. Then, the thickness of the non-bituminous root-resistant rubber compound coated on the upper and lower surfaces of the copper matrix 2 is adjusted by rolling with the thickness-setting roller 6.

[0089] (4) The upper and lower sets of traction rollers 1 respectively pull another layer of copper matrix 2 and a layer of film to be laminated on the upper and lower surfaces of the non-bituminous root-resistant rubber compound coated on the upper and lower surfaces of the copper matrix; the layer of film is one of the PE film 7 and the anti-aging PE isolation film 8 (the anti-aging PE isolation film 8 is exemplified in the figure), and the other layer of copper matrix 2 is first dried in step (1) and pre-impregnated with oil in step (2) before lamination.

[0090] (5) Then, it is pulled by the traction roller 1 into another oil coating tank 5. After the non-bituminous root-resistant rubber compound preheated to 165 - 175 °C is coated on the upper surface of the other layer of copper matrix 2 through the upper oil coating roller 4, another layer of film is laminated on the upper surface of the coated non-bituminous root-resistant rubber compound and rolled to form a waterproof coiled material; or while another layer of film is laminated on the upper surface of the other layer of copper matrix 2, the non-bituminous root-resistant rubber compound preheated to 165 - 175 °C is injected into the gap between the upper surface of the other layer of copper matrix 2 and another layer of film ( Figure 4 not shown in the figure), and rolled to form a waterproof coiled material; the other layer of film is the other one of the PE film 7 and the anti-aging PE isolation film 8 (the PE film 7 is exemplified in the figure);

[0178]

[0179]

[0180] The non-bituminous root-resistant rubber compound of the present invention adopts a non-bituminous base system and internally adds antioxidants to overcome the drawback of the fast aging rate of bituminous materials, further improve the anti-aging performance of the material, and extend the service life of the material. And it does not add waste tire rubber powder and low-mesh mineral powder, reduces the generation of benzene series substances during the production process, improves the environmental protection performance of the material, and at the same time the material is softer and more delicate, and the construction odor is lower. It uses SBS plus SIS as the macromolecular skeleton, with both high strength and super flexibility, and is paired with styrene-butadiene rubber to provide the material with adhesiveness. The low temperature can reach -30°C, the low-temperature attenuation of the material is less than 2°C in 14 days, and at the same time, the aluminum plate peel exceeds 1.5 N / mm, and cold bonding construction can be adopted.

[0181] The waterproof coiled material of the present invention adopts double copper tire base plus root-resistant agent for chemical and physical double root resistance to ensure good root resistance performance of the material. At the same time, the double tire base structure improves the mechanical properties of the material, which can reach more than 2000 N, far exceeding the mechanical properties of conventional coiled materials of 800 N, and ensures the anti-deformation ability of the waterproof system.

[0182] The waterproof coiled material of the present invention has passed the artificial weather aging test for 720 hours. The cumulative radiation energy at a wavelength of 340 nm should not be less than 5040 KJ / (㎡·nm). After the test, no cracking, delamination, blistering, bonding, holes and other phenomena occur in the material, and it is applicable to the scenario of planting roof without concrete protection layer.

[0183] To verify the effectiveness of the composition ratio of the non-bituminous root-resistant rubber compound in the present invention, the following 12 comparative examples are set. All the comparative examples are prepared into corresponding 12 non-bituminous root-resistant rubber compounds according to the preparation method of Example 1, and the actual application effects are tested by changing the composition ratio. The composition components of each comparative example are as follows in fraction ratio:

[0184]

[0185] Twelve non-bituminous root-resistant rubber materials as described above were respectively used to prepare non-bituminous root-resistant rubber waterproof coiled materials according to the preparation method in Example 1, and then the waterproof coiled materials of these twelve cases were tested according to different test methods. The test results are shown in the following table:

[0186]

[0187] The following conclusions can be drawn from the results in the above table:

[0188] From Comparative Examples 1-2, it can be seen that the pour point of the high-viscosity aromatic oil is relatively low, which has an obvious impact on low temperature and peel effect. When the addition ratio is 18% (Comparative Example 1), its low-temperature performance is better than that of Example 1, but the peel index is unqualified; when the addition ratio is 26% (Comparative Example 2), the low-temperature limit before aging decreases significantly, and the low temperature after aging is unqualified.

[0189] From Comparative Examples 3-4, it can be seen that the pour point of the low-viscosity aromatic oil is high and the viscosity is low. When the addition ratio is 28% (Comparative Example 3), the low-temperature limit decreases and the low temperature after thermal aging is unqualified. When the addition ratio is 36%, the material viscosity is too thin, and both high temperature and peel are unqualified.

[0190] From Comparative Examples 5-8, it can be seen that if SBS is combined with SIS as the main modifier to construct a macromolecular framework, SBS has a large cohesive force to provide strength, and the SIS segment is relatively long and has better flexibility, which is more beneficial to low temperature. When the addition ratio of SBS is 0.5% (5 and 7), the strength of the material's macromolecular structure is relatively low, and the aging attenuation is serious. Even by increasing the addition amount of SIS, the low-temperature attenuation cannot be slowed down. When the addition amount of SBS is 4%, the strength of the material skeleton is too high, resulting in a straight-line decline in the peel effect and being unqualified; when the addition ratio of SIS is less than 6%, the low-temperature margin is small, and the low temperature before and after thermal aging is unqualified. Therefore, in order to ensure the viscosity and anti-aging ability of the material, SBS (2%) + SIS (8%) is the best ratio.

[0191] From Comparative Example 9, it can be seen that when the addition amount of styrene-butadiene rubber is less than 11% (Comparative Examples 9 and 10), the viscosity of the material decreases and the aluminum plate peel index is unqualified. As the ratio increases, the aluminum plate data improves significantly.

[0192] From Comparative Example 11, it can be seen that when the addition amount of the antioxidant is 0.7%, the low-temperature attenuation after thermal aging is serious, resulting in the low temperature after aging being unqualified.

[0193] From Comparative Example 12, it can be seen that when the addition amount of the root inhibitor is 0.8%, the root penetration resistance performance of the material decreases and the penetration test is unqualified.

[0194] As mentioned above, the above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes should be covered within the protection scope of the present invention.
