Description

TECHNICAL FIELD

[0001] The present application relates to the field of waterproofing membranes, more particularly, the present application relates to a production method of a flame-retardant waterproofing membrane. BACKGROUND

[0002] A waterproofing membrane is a sheet-like waterproofing material that can be rolled up. It is mainly made of asphalt or high polymer materials. It is mainly used in the roofing, basement, bathroom and other parts of buildings to prevent water penetration. It can effectively prevent the intrusion of liquid water such as rainwater and groundwater, protect the structure of the building from water erosion, and thus prolong the service life of the building.

[0003] Currently, the key steps in the preparation of flame-retardant waterproofing membranes are mixing and extrusion. However, the mixing effect is poor when mixing the raw materials of the flame-retardant waterproofing membrane with a mixer, which cannot guarantee the mixing effect well, and thus may affect the production quality of the flame-retardant waterproofing membrane. In addition, an extruder is used for extruding the flame-retardant waterproofing membrane, but it is not convenient to monitor the state of the extruder. When the state of the extruder is abnormal, it will affect the production quality of the flame-retardant waterproofing membrane, which has certain limitations.

[0004] In order to solve the above problems, a technical scheme is provided. SUMMARY

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present application provide a production method of a flame-retardant waterproofing membrane to solve the problems raised in the background art.

[0006] To achieve the above object, the present application provides the following technical scheme: A production method of a flame-retardant waterproofing membrane, comprising the following steps: S1: preparing a high polymer, a flame retardant, a smoke suppressant, a filler and an additive; S2: adding the high polymer, the flame retardant, the smoke suppressant, the filler and the additive into a mixing device for mixing treatment; S3: using an extruder to extrude the mixed material into a shape; S4: performing calendering, cooling and setting treatment on the extruded material to obtain a waterproofing membrane.

[0007] In a preferred embodiment, step S1 specifically includes the following contents: The high polymer is polyethylene, the flame retardant is a bromine-based flame retardant, the smoke suppressant is melamine cyanurate, the filler is talcum powder, the additive is a plasticizer and a stabilizer, the plasticizer is dibutyl phthalate, and the stabilizer is a phosphite antioxidant.

[0008] In a preferred embodiment, step S2 specifically includes the following: The flame retardant and filler are magnetized. A magnetic field generator is placed around the mixing equipment; Polymers, flame retardants, smoke suppressants, fillers, and additives are added to a mixing device and mixed under the influence of a magnetic field until the optimal effect is achieved.

[0009] In a preferred embodiment, the magnetic field strength generated by the magnetic field generator is set to M, and its value ranges from [value range missing]. The current magnetic field strength is marked as ; Set the mixing time to T, with a value ranging from... The current mixing time is marked as ; Let G be the label of the mixing uniformity, and its expression is: ; in, To adjust the coefficient, Viscosity under ideal mixing conditions The viscosity during the current mixing process. The temperature under ideal mixing conditions. The temperature during the current mixing process. This represents the force exerted on the particle by the current magnetic field. This represents the maximum force exerted by the magnetic field on the particle.

[0010] In a preferred embodiment, a mixing uniformity threshold is set, and the mixing uniformity is compared with the mixing uniformity threshold. If the mixing uniformity is less than the mixing uniformity threshold, adjust the magnetic field strength or mixing time until the mixing uniformity reaches the preset mixing uniformity threshold.

[0011] By adopting the above technical solution, setting a mixing uniformity threshold provides a clear standard for the mixing effect of the product, ensuring that the produced flame-retardant waterproof membrane has high performance consistency. This avoids local performance differences caused by uneven mixing, thereby improving the overall quality stability of the product. When the mixing uniformity does not meet the standard, the magnetic field strength or mixing time can be adjusted to reach the preset threshold, ensuring that the product is always produced under good mixing conditions and reducing the negative impact of poor mixing on product quality. In a preferred embodiment, step S3 specifically includes the following: Collect the extruder's equipment parameters, including screw wear rate, barrel deformation rate, internal heating temperature coefficient, and internal cooling temperature coefficient; The screw wear rate is labeled MSL, the barrel deformation rate is labeled BXL, the internal heating temperature coefficient is labeled GR, and the internal cooling temperature coefficient is labeled LQ. The range of values ​​for screw wear rate (MSL) is as follows: ; The range of values ​​for the barrel deformation rate BXL is: ; The range of values ​​for the internal heating temperature coefficient GR is as follows: ; The range of values ​​for the internal cooling temperature coefficient LQ is: ; After normalizing the screw wear rate, barrel deformation rate, internal heating temperature coefficient, and internal cooling temperature coefficient, the extruder condition coefficient is established, and the calculation formula is as follows: ;in, These are the weighting coefficients for screw wear rate, barrel deformation rate, internal heating temperature coefficient, and internal cooling temperature coefficient, respectively. This is the extruder condition coefficient.

[0012] By adopting the above technical solution, normalization processing makes different parameters comparable, unifying parameters at different scales under the same standard, which facilitates comprehensive analysis and weight allocation. The weighting coefficients can be flexibly adjusted according to the importance of each parameter to the extruder's condition, highlighting the influence of key parameters while not neglecting secondary parameters. An extruder condition coefficient is established, integrating multiple parameters into a single specific value, intuitively reflecting the current state of the extruder. Operators can quickly understand the extruder's operating status, providing a basis for timely maintenance or adjustment measures.

[0013] In a preferred embodiment, a large amount of operating data of similar extruders is collected, including parameters such as screw wear rate, barrel deformation rate, internal heating temperature coefficient and internal cooling temperature coefficient. These data are analyzed and statistically analyzed, and the extruder state coefficient threshold is set based on the results of the statistical analysis. If the extruder condition coefficient is greater than or equal to the extruder condition coefficient threshold, it indicates that the extruder is operating well. If the extruder condition coefficient is within the extruder condition coefficient threshold range, it indicates that the extruder is operating normally, but its changing trend needs to be closely monitored. If the extruder condition coefficient is less than the extruder condition coefficient threshold, it indicates that the extruder is in an abnormal operating condition and needs to be stopped immediately for maintenance.

[0014] By adopting the above technical solution, and analyzing and statistically determining the extruder condition coefficient threshold through the collection of a large amount of operational data from similar extruders, this method fully considers the diversity of actual operating conditions, making the threshold determination more scientific and accurate. It avoids the deviations that may arise from setting thresholds based solely on experience or limited data, providing a reliable standard for accurately judging the extruder condition. This enables refined management of the extruder, allowing for corresponding measures to be taken according to different conditions, thus improving the pertinence and effectiveness of equipment management. It also provides a scientific basis for rationally scheduling production plans, maximizing production efficiency and comprehensively improving the level of production management.

[0015] In a preferred embodiment, step S4 specifically includes the following: A calender is used to calender materials that have been extruded. Air cooling is used to cool and shape the calendered material.

[0016] The technical effects and advantages of the method for producing flame-retardant waterproof membrane according to the present invention are as follows: 1. By magnetizing the flame retardant and filler and mixing them with a magnetic field generator, the dispersibility and binding force of the material are enhanced, making the components more evenly distributed in the polymer. This avoids localized flame retardancy or poor reinforcement effects, improves the overall performance and quality stability of the product, and precisely controls the mixing process to ensure that the mixing uniformity reaches the preset threshold, avoiding local performance differences caused by uneven mixing, further improving product quality. Comprehensive monitoring of the extruder status allows for timely detection and handling of equipment abnormalities, ensuring the stability and consistency of the extrusion process, thereby improving the production quality of waterproof membranes. 2. Magnetic field-assisted mixing accelerates the mixing speed, reduces mixing time, and improves production efficiency. Simultaneously, it avoids over-mixing, saving time and energy, reducing production costs. Production plans can be rationally arranged based on the extruder's condition, increasing production when equipment is in good condition and promptly stopping for maintenance when abnormal conditions occur, thus avoiding production stoppages due to equipment failure and improving the flexibility and adaptability of production efficiency. 3. By collecting multiple equipment parameters to establish an extruder status coefficient and setting thresholds based on a large amount of operating data from similar extruders, refined management of the extruder status is achieved. Operators can take corresponding measures according to different statuses, improving the pertinence and effectiveness of equipment management. Real-time monitoring of the extruder status facilitates the early detection of potential problems and the implementation of preventive measures, extending the service life of the equipment and reducing maintenance costs. Clear mixing uniformity standards and adjustable mixing parameters make the production process more controllable and can be optimized according to different material batches and production environments, improving the scientific nature and stability of production management. Attached Figure Description

[0017] Figure 1 This is a schematic flowchart of a method for producing a flame-retardant waterproof membrane according to the present invention. Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 Figure 1 This invention provides a method for producing a flame-retardant waterproof membrane, comprising the following steps: S1: Prepare polymers, flame retardants, smoke suppressants, fillers, and additives; S2: Add the polymer, flame retardant, smoke suppressant, filler and additives into the mixing equipment for mixing; S3: The mixed materials are extruded and molded using an extruder; S4: The extruded material is calendered, cooled and shaped to obtain a waterproof membrane.

[0020] Step S1 specifically includes the following: The polymer is polyethylene, the flame retardant is a brominated flame retardant, the smoke suppressant is melamine cyanurate, the filler is talc, and the additives are plasticizers and stabilizers. The plasticizer is dibutyl phthalate, and the stabilizer is a phosphite antioxidant.

[0021] It should be noted that the polymer, flame retardant, smoke suppressant, filler, and additives can be composed of the following components: 120 parts polymer, 60 parts flame retardant, 45 parts smoke suppressant, 30 parts filler, and 14 parts additives. The polymer serves as the main material of the waterproof membrane, providing excellent waterproof performance. The addition of the flame retardant can significantly improve the flame retardant performance of the waterproof membrane, and the addition of the smoke suppressant can significantly improve the smoke suppression performance of the waterproof membrane. The filler is used to enhance the strength and stability of the waterproof membrane, and the additives can improve the processing performance and service life of the waterproof membrane.

[0022] Step S2 specifically includes the following: The flame retardant and filler are magnetized. A magnetic field generator is placed around the mixing equipment; Polymers, flame retardants, smoke suppressants, fillers, and additives are added to a mixing device and mixed under the influence of a magnetic field until the optimal effect is achieved.

[0023] The advantage of this method is that magnetized flame retardants and fillers are more easily and uniformly dispersed in the polymer during mixing. Due to the magnetic field, the interaction forces between particles change, reducing agglomeration and allowing them to be more widely distributed in the matrix, improving the overall uniformity of the material. This helps ensure that flame retardants and fillers play a more stable role in waterproof membranes, avoiding localized poor flame retardancy or reinforcement.

[0024] Magnetization treatment can alter the surface properties of flame retardants and fillers, increasing their affinity for polymers. This enhanced bonding can improve the mechanical properties and stability of the material, reducing the shedding or migration of flame retardants and fillers during use. For example, better bonding makes the material more resistant to tension, bending, and impact when subjected to external forces, extending the service life of waterproof membranes.

[0025] The magnetic field exerts forces on the magnetized flame retardants and fillers, promoting a more uniform distribution of them within the mixing equipment. This uniform mixing is crucial for the performance of waterproof membranes, as uneven distribution can lead to localized performance differences, affecting the overall quality of the product. Simultaneously, the magnetic field can also influence the flow behavior of the polymer molecules, further promoting the uniform mixing of the components.

[0026] Magnetic field-assisted mixing can accelerate the mixing speed and reduce mixing time. Compared with traditional mixing methods, the magnetic field can accelerate particle diffusion and interaction, making the mixing process more efficient. This not only improves production efficiency and reduces production costs, but also reduces energy consumption and equipment wear.

[0027] Magnetizing flame retardants and fillers, setting up a magnetic field generator, and mixing them under the action of a magnetic field can bring many benefits, such as enhanced dispersibility, improved binding force, precise control of the mixing process, promotion of uniform mixing, improved production efficiency, synergistic effect, optimized product performance, and environmental protection and energy saving.

[0028] In a preferred embodiment, the magnetic field strength generated by the magnetic field generator is set to M, and its value ranges from [value range missing]. The current magnetic field strength is marked as ; Set the mixing time to T, with a value ranging from... The current mixing time is marked as ; Let G be the label of the mixing uniformity, and its expression is: ; in, To adjust the coefficient, Viscosity under ideal mixing conditions The viscosity during the current mixing process. The temperature under ideal mixing conditions. The temperature during the current mixing process. This represents the force exerted on the particle by the current magnetic field. This represents the maximum force exerted by the magnetic field on the particle.

[0029] The advantage of this approach is that, by clearly defining the range of magnetic field strength and marking the current magnetic field strength, the magnetic field parameters can be precisely adjusted according to different material properties and mixing requirements. This makes the mixing process more controllable and allows for optimization of specific combinations of polymers, flame retardants, smoke suppressants, fillers, and additives.

[0030] The system allows operators to set a range for mixing time and mark the current mixing time, enabling them to flexibly adjust the mixing process duration based on actual conditions. Different materials may require different mixing times to achieve the desired uniformity, and this setting can meet diverse production needs.

[0031] By providing an expression for mixing uniformity and incorporating factors such as viscosity, temperature, and magnetic field forces, the mixing effect can be quantified more accurately. This allows operators to intuitively understand the degree of mixing, providing a basis for further adjustments and optimizations.

[0032] Set a mixing uniformity threshold and compare the mixing uniformity with the mixing uniformity threshold; If the mixing uniformity is less than the mixing uniformity threshold, adjust the magnetic field strength or mixing time until the mixing uniformity reaches the preset mixing uniformity threshold.

[0033] The advantage of this approach is that by setting a mixing uniformity threshold, an acceptable mixing quality standard can be clearly defined. This helps ensure high consistency in the performance of the produced waterproof membranes, avoiding localized performance differences caused by uneven mixing, thereby improving the overall quality stability of the product.

[0034] The process of comparing mixing uniformity with a threshold provides real-time feedback to the production process. Operators can adjust the magnetic field strength or mixing time in a timely manner based on this feedback, achieving precise control over the mixing process. This dynamic adjustment method can be optimized according to different material batches, production environments, and other factors to achieve the best mixing effect. For example, when the properties of the material change, parameters can be adjusted to adapt to the new situation, ensuring that the mixing uniformity always meets the requirements.

[0035] Unnecessary overmixing can be avoided by adjusting parameters in a timely manner to reach the threshold. Overmixing can waste time and energy, increase production costs, and may also have adverse effects on material properties.

[0036] Ensuring proper mixing uniformity can reduce localized performance deficiencies caused by uneven material distribution. This means that, while maintaining product quality, the excessive use of certain materials can be reduced, thereby lowering material costs.

[0037] Step S3 specifically includes the following: Collect the extruder's equipment parameters, including screw wear rate, barrel deformation rate, internal heating temperature coefficient, and internal cooling temperature coefficient; The screw wear rate is labeled MSL, the barrel deformation rate is labeled BXL, the internal heating temperature coefficient is labeled GR, and the internal cooling temperature coefficient is labeled LQ. The range of values ​​for screw wear rate (MSL) is as follows: ; The range of values ​​for the barrel deformation rate BXL is: ; The range of values ​​for the internal heating temperature coefficient GR is as follows: ; The range of values ​​for the internal cooling temperature coefficient LQ is: ; After normalizing the screw wear rate, barrel deformation rate, internal heating temperature coefficient, and internal cooling temperature coefficient, the extruder condition coefficient is established, and the calculation formula is as follows: ;in, These are the weighting coefficients for screw wear rate, barrel deformation rate, internal heating temperature coefficient, and internal cooling temperature coefficient, respectively. This is the extruder condition coefficient.

[0038] The advantage of this approach is that collecting multiple equipment parameters provides a comprehensive reflection of the extruder's operating status from various perspectives. Screw wear rate reflects the wear and tear on key components, barrel deformation rate relates to extrusion precision and stability, and internal heating and cooling temperature coefficients affect material processing performance and product quality. By integrating these parameters, a more comprehensive understanding of the extruder's overall condition can be obtained. This avoids the limitations of evaluating a single parameter and allows for the timely detection of potential problems. For example, focusing solely on screw wear rate might overlook issues such as barrel deformation or improper temperature control, while integrating multiple parameters provides a more accurate assessment of the extruder's condition.

[0039] The ranges of values ​​for different parameters can vary greatly. Normalization can unify them to the same scale, facilitating comprehensive analysis. For example, the screw wear rate may be between 0% and 10%, while the temperature coefficient may be between 0 and 1. Normalization allows the influence of these parameters to be considered within the same framework.

[0040] After normalization, the allocation of weighting coefficients becomes more intuitive and reasonable. The weighting coefficients can be flexibly adjusted based on the importance of each parameter to the extruder's condition, highlighting the impact of key parameters while not neglecting changes in secondary parameters.

[0041] The extruder condition coefficient, obtained through calculation, is a specific numerical value that directly reflects the current state of the extruder. This allows operators to quickly understand the extruder's operating status and take timely maintenance or adjustment measures.

[0042] Extruder condition coefficients can serve as an important basis for decision-making. For example, when scheduling production, appropriate production tasks can be selected based on the extruder condition coefficient, avoiding high-load production when the equipment is in poor condition. Furthermore, the condition coefficient can also be used to determine whether equipment maintenance or component replacement is necessary.

[0043] Collect a large amount of operating data from similar extruders, including parameters such as screw wear rate, barrel deformation rate, internal heating temperature coefficient, and internal cooling temperature coefficient. Analyze and statistically process this data, and set the extruder state coefficient threshold based on the results of the statistical analysis. If the extruder condition coefficient is greater than or equal to the extruder condition coefficient threshold, it indicates that the extruder is operating well. If the extruder condition coefficient is within the extruder condition coefficient threshold range, it indicates that the extruder is operating normally, but its changing trend needs to be closely monitored. If the extruder condition coefficient is less than the extruder condition coefficient threshold, it indicates that the extruder is in an abnormal operating condition and needs to be stopped immediately for maintenance.

[0044] The advantage of this approach is that, by considering various actual operating conditions, the set thresholds can adapt to different production environments and working requirements. Whether under high load, long-term operation, or with different process parameter settings, the operating status of the extruder can be determined relatively accurately.

[0045] When the extruder condition coefficient is greater than or equal to the threshold, it indicates that the extruder is operating well. This allows operators to carry out production with confidence, improves production efficiency, and also reduces unnecessary inspection and maintenance work, thereby lowering production costs. When the extruder's condition coefficient is within the threshold range, although the operation is normal, it is important to closely monitor its changing trend. This allows operators to identify potential problems early and take timely preventative measures to avoid further deterioration. For example, production plans can be adjusted, loads appropriately reduced, or maintenance can be scheduled in advance to extend the extruder's service life. When the extruder's condition coefficient falls below a threshold, it indicates an abnormal operating condition, requiring immediate shutdown and maintenance. This timely response prevents further damage from continued operation, reducing maintenance costs and downtime. Simultaneously, it ensures production safety and prevents accidents caused by equipment malfunctions.

[0046] By monitoring and classifying the extruder's status in real time, refined equipment management can be achieved. Operators can take appropriate measures based on different statuses, improving the targetedness and effectiveness of equipment management.

[0047] The proper functioning of the extruder is a crucial prerequisite for ensuring stable product quality. By promptly identifying and resolving extruder issues, the stability and consistency of the production process can be guaranteed, thereby improving the product quality pass rate.

[0048] Based on the condition of the extruder, production plans can be rationally arranged. When the extruder is in good condition, production can be increased; when its condition requires monitoring, the production schedule can be adjusted appropriately; and when its condition is abnormal, timely maintenance should be carried out to avoid excessive impact on the production plan. This improves the flexibility and adaptability of the production plan, maximizing production efficiency.

[0049] Step S4 specifically includes the following: A calender is used to calender materials that have been extruded. Air cooling is used to cool and shape the calendered material.

[0050] The advantage of this method is that calendering makes the extruded material more compact, increasing its density and uniformity. This helps enhance the physical properties of the waterproof membrane, such as strength, toughness, and abrasion resistance. Using a calender to calender the extruded material, followed by air cooling to cool and shape the calendered material, offers numerous benefits, including improved material properties, enhanced surface quality, increased production efficiency, rapid cooling, energy saving, environmental friendliness, and ease of operation.
