Description

Technical Field

[0001] The invention relates to the field of coating processing, in particular to a coating debugging processing control method. Background Art

[0002] The production process of coatings is mainly a physical mixing process. Its main raw materials include resin (film-forming substance) and solvent. In addition, an appropriate amount of additives needs to be added during the mixing process. The additives include emulsifiers, wetting and dispersing agents, defoaming agents and solid coating additives (such as cellulose, pigments), etc. During the physical stirring and mixing of the raw materials, the wetting and dispersing agents mainly play the role of stabilizing the dispersion of solid particles and preventing the tiny particles of solid coatings from aggregating together to form agglomerated particles. The defoaming agent is mainly used to eliminate tiny bubbles in the mixing process. Solid coating additives are mainly used for coating color adjustment, etc.

[0003] During the actual processing and debugging of coatings, the weight of various raw materials added to different types of coatings will also be different. Therefore, when studying new types of coating formulas, it is necessary to debug the amount and proportion of each basic raw material one by one. The current operation method is that people rely on their own operating experience and previous related coating formulas to gradually debug the raw materials that may change in addition in the new coating formula, and then record the added amount of the raw materials that have changed after debugging. If a coating with qualified performance is obtained, it is considered that the debugging is successful. If the coating performance is unqualified, it is considered that the debugging is unsuccessful.

[0004] The current coatings have the following drawbacks during the debugging process: 1. After the current coatings are debugged, the properties of different raw materials are not monitored item by item during the quality monitoring. If the coatings fail to meet the performance requirements at the same time, the addition ratios of the various raw materials need to be arranged and combined. During the debugging process, the target data of each raw material is difficult to find, and the direction of data adjustment is relatively vague.

[0005] 2. After the current paint is debugged, the amount of each raw material added will gradually change. The entire data change process needs to be recorded in real time. The current paint reactor is not equipped with a relatively complete monitoring system. Summary of the invention

[0006] The purpose of the present invention is to solve the defects of the prior art and provide a coating debugging and processing control method.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] The debugging and processing control method of the coating includes the following steps:

[0009] S1. Inject the resin raw material and solvent into the reactor and continue stirring, and record the injected mass of the resin raw material as m, and record the injected mass of the solvent as n;

[0010] S2. injecting an emulsifier into the reactor through the first feeding mechanism and continuously stirring, and recording the injection mass of the emulsifier as a;

[0011] S3. Injecting a wetting and dispersing agent into the reactor through a second feeding mechanism and continuing stirring, and recording the injection mass of the wetting and dispersing agent is b;

[0012] S4. The defoamer is injected into the reactor through a third feeding mechanism and continued stirring, and the injection mass of the defoamer is recorded as c;

[0013] S5. The pigment is injected into the reactor through the fourth feeding mechanism and continued stirring, and the injection mass of the pigment is recorded as d;

[0014] S6. The resin raw material, solvent, emulsifier, wetting dispersant, defoamer and pigment in the reactor are fully stirred and mixed to form a first debugging coating. The first debugging coating is sampled and applied on a sample. The first debugging coating layer on the sample is observed. After the observation is completed, the situation is recorded. The sample coated with the first debugging coating layer is sent to a baking room for a baking experiment. The baking time is 5-10 hours. Then, the appearance change of the first debugging coating layer is observed and the change is recorded.

[0015] S7. Analyze the changes of the first debugging coating layer fed back by S6 one by one;

[0016] S8. If the first debugging coating layer is applied to the surface of the sample, the color depth of the coating layer does not meet the standard, the control system controls the fourth feeding mechanism to intermittently inject pigment into the reactor, and the amount of pigment injected is recorded cumulatively, and the quality data recorded is d1, d2 ... dn;

[0017] Each time the pigment is injected, the reactor is fully stirred and the debug paint is exported. The exported debug paint is applied to a new sample and the color depth is observed. The pigment mass is gradually added many times. Each time the pigment is added, a coating experiment is performed until the color depth reaches the standard. The pigment mass data in the debug paint when the color depth reaches the standard is d k That is the target data;

[0018] S9. After the first debugging coating layer is coated on the surface of the sample, the sample coated with the first debugging coating layer is sent to the baking room for baking experiment. If cracks appear on the surface of the first debugging coating layer, the control system controls the first feeding mechanism to intermittently inject emulsifier into the reactor. When recording the injection amount of the emulsifier, it is cumulatively recorded, and the recorded quality data is a1, a2…an;

[0019] Each time the emulsifier is injected, the reactor is fully stirred, and the debug coating is exported. The exported debug coating is coated on a new sample and a baking test is carried out. The emulsifier is added gradually for many times. Each time the emulsifier is added, a coating test is carried out until the debug coating layer does not crack after the baking test. The quality data of the emulsifier in the debug coating when it meets the standard is a k That is the target data;

[0020] S10. After the first debugging coating layer is coated on the surface of the sample, the sample coated with the first debugging coating layer is sent to the baking room for baking experiment. If particle protrusions appear on the surface of the first debugging coating layer, the control system controls the second feeding mechanism to intermittently inject a wetting and dispersing agent into the reactor. The injection amount of the wetting and dispersing agent is recorded cumulatively, and the recorded quality data is b1, b2...bn;

[0021] Each time the wetting and dispersing agent is injected, the reactor is fully stirred and the debugging paint is exported. The exported debugging paint is coated on a new sample and a baking test is carried out. The wetting and dispersing agent is gradually added many times. Each time the wetting and dispersing agent is added, a coating test is carried out until no particles or protrusions appear in the debugging paint layer after the baking test. The quality data of the wetting and dispersing agent in the debugging paint that meets the standard is b k That is the target data;

[0022] S11. After the first debugging coating layer is coated on the surface of the sample, the sample coated with the first debugging coating layer is sent to the baking room for baking experiment. If there are pores in the cross section of the first debugging coating layer, the control system controls the third feeding mechanism to intermittently inject defoaming agent into the reactor. When recording the injection amount of the defoaming agent, it is cumulatively recorded, and the recorded quality data is c1, c2…cn;

[0023] Each time the defoamer is injected, the reactor is fully stirred and the debug coating is exported. The exported debug coating is coated on a new sample and a baking test is carried out. The defoamer is added gradually for many times. Each time the defoamer is added, a coating test is carried out until no pores appear in the cross section of the debug coating layer after the baking test. The defoamer quality data c in the debug coating that meets the standard k This is the target data.

[0024] According to the technical scheme, the method first injects basic weight portions of resin raw materials, solvents, emulsifiers, wetting and dispersing agents, defoaming agents, and pigments into a reaction kettle, and fully stirs and mixes them to form a first debugging coating. The various properties of the first debugging coating are monitored separately. When a certain property is unqualified, the corresponding raw materials are gradually added for the unqualified performance until the performance monitoring is qualified. Then, the raw materials corresponding to another performance are gradually debugged, and the cycle is repeated until the various properties of the coating are qualified. The method monitors the properties of different raw materials one by one, and the purpose of monitoring is strong. Moreover, the method of adding raw materials one by one can achieve high-precision adjustment of the raw material ratio.

[0025] In addition, this method adopts the synchronous monitoring of the appearance of the coating layer and the use environment, which can not only perform preliminary monitoring of the actual form of the coating, but also monitor the effect of the coating after use. This application combines the real-time performance monitoring of the coating with the coating debugging system. According to the changes in various performance properties of the coating, the addition amount of various raw materials in the coating is reversely changed. The performance monitoring and debugging systems of the coating complement each other, and the adjustment of the raw material addition amount is relatively clear.

[0026] Furthermore, the emulsifier quality data a k , wetting and dispersing agent quality data b k , defoamer quality data c k , Pigment quality data d k After confirmation, the raw materials in the reactor are cleaned. After cleaning, the resin raw material with a mass of m is injected into the reactor again, and the solvent with a mass of n is injected at the same time. At the same time, according to the mass data a k Inject emulsifier, according to quality data b k Injection of wetting and dispersing additive, according to quality data c k Inject defoamer according to quality data d k After the pigment and raw materials are injected, the temperature in the reactor is controlled by the temperature control system, and the temperature environment of the reactor is recorded respectively, and the temperature data are t1, t2…tn;

[0027] After each adjustment of the temperature data, the raw materials in the reactor are fully stirred, that is, a debugging coating is exported, the exported debugging coating is coated on a new sample and a baking experiment is carried out, and the temperature data is gradually adjusted many times. Each time the temperature data is adjusted, a coating experiment is carried out. When the debugging coating layer is in the best state after the baking experiment, the temperature data set in the reactor t k This is the target data.

[0028] Through the above technical solution, after the target data of the addition amount of the resin raw material, solvent, emulsifier, wetting dispersant, defoamer and pigment of the coating are found, the temperature control system gradually controls the temperature of the environment where the reactor is located. Under different temperature environments, the coating processed according to the target data is correspondingly monitored for performance. After the performance monitoring, when the coating layer reaches the optimal state, the temperature data t set in the reactor k That is the target data. The debugging process of raw material addition ratio is independent of the temperature debugging process. In this method, the target data of each raw material is first found through the debugging system, and then the target data of the temperature of the coating processing environment is found through the gradual debugging of the temperature control system. During the coating debugging process, the adjustment direction of each parameter is relatively clear.

[0087] S6. The resin raw material, solvent, emulsifier, wetting dispersant, defoamer and pigment in the reactor 1 are fully stirred and mixed to form a first debugging coating. The first debugging coating is sampled and coated on the sample 2. The first debugging coating layer on the sample 2 is observed. After the observation is completed, the situation is recorded, and the sample 2 coated with the first debugging coating layer is sent to the baking room 3 for baking experiment (the temperature in the baking room 3 can be set at 40-60 degrees), the baking time is 5-10 hours, and then the appearance change of the first debugging coating layer is observed and the change is recorded;

[0088] S7. Analyze the changes of the first debugging coating layer fed back by S6 one by one;

[0089] S8. If the first debugging coating layer is applied to the surface of the sample, the color depth of the coating layer does not meet the standard, the control system 50 controls the fourth feeding mechanism 40 to intermittently inject pigment into the reactor 1, and the amount of pigment injected is recorded cumulatively, and the quality data recorded is d1, d2 ... dn;

[0090] Each time the pigment is injected, the reactor 1 is fully stirred and the debugged paint is exported. The exported debugged paint is coated on a new sample 2 and the color depth is observed. The pigment mass is gradually added many times. Each time the pigment is added, a coating experiment is performed until the color depth reaches the standard. The pigment mass data d in the debugged paint when the color depth reaches the standard k That is the target data;

[0091] S9. After the first debugging coating layer is coated on the surface of the sample 2, the sample 2 coated with the first debugging coating layer is sent to the baking room 3 for baking experiment. If cracks appear on the surface of the first debugging coating layer, the control system 50 controls the first feeding mechanism 10 to intermittently inject emulsifier into the reactor 1. When recording the injection amount of the emulsifier, the cumulative record is made, and the recorded quality data is a1, a2…an;

[0092] Each time the emulsifier is injected, the reactor 1 is fully stirred, and the debug coating is exported. The exported debug coating is coated on a new sample 2 and a baking test is carried out. The emulsifier is gradually added for many times. Each time the emulsifier is added, a coating test is carried out until the debug coating layer does not crack after the baking test. The emulsifier quality data a in the debug coating that meets the standard k That is the target data;

[0093] S10. After the first debugging coating layer is coated on the surface of the sample 2, the sample 2 coated with the first debugging coating layer is sent to the baking room 3 for baking experiment. If particle protrusions appear on the surface of the first debugging coating layer, the control system controls the second feeding mechanism 20 to intermittently inject a wetting and dispersing agent into the reactor 1. When recording the injection amount of the wetting and dispersing agent, a cumulative record is made, and the recorded quality data is b1, b2…bn;

[0094] Each time the wetting and dispersing agent is injected, the reactor 1 is fully stirred, and the debug coating is exported. The exported debug coating is coated on a new sample 2 and a baking test is carried out. The wetting and dispersing agent is gradually added for many times. Each time the wetting and dispersing agent is added, a coating test is carried out until no particle protrusions appear in the debug coating layer after the baking test. The quality data of the wetting and dispersing agent in the debug coating when it meets the standard is b k That is the target data;

[0095] S11. After the first debugging coating layer is coated on the surface of the sample, the sample 2 coated with the first debugging coating layer is sent to the baking room 3 for baking experiment. If there are pores in the cross section of the first debugging coating layer, the control system controls the third feeding mechanism 30 to intermittently inject defoaming agent into the reactor. When recording the injection amount of the defoaming agent, it is cumulatively recorded, and the recorded quality data is c1, c2…cn;

[0096] Each time the defoamer is injected, the reactor 1 is fully stirred, and the debug coating is exported. The exported debug coating is coated on a new sample 2 and a baking test is carried out. The defoamer is added step by step for many times. Each time the defoamer is added, a coating test is carried out until no pores appear in the cross section of the debug coating layer after the baking test. The defoamer quality data c in the debug coating that meets the standard k This is the target data.

[0097] Furthermore, the emulsifier quality data a k , wetting and dispersing agent quality data b k , defoamer quality data c k , Pigment quality data d kAfter confirmation, the raw materials in the reactor are cleaned. After cleaning, the resin raw material with a mass of m is injected into the reactor 1 again, and the solvent with a mass of n is injected at the same time. At the same time, according to the mass data a k Inject emulsifier, according to quality data b k Injection of wetting and dispersing additive, according to quality data c k Inject defoamer according to quality data d k After the pigment is injected and the raw material is injected, the temperature in the reactor is controlled by the temperature control system 60, and the temperature environment of the reactor is recorded, and the temperature data are t1, t2 ... tn;

[0098] After each adjustment of the temperature data, the raw materials in the reactor 1 are fully stirred, that is, a debugging coating is exported, and the exported debugging coating is coated on a new sample 2 and a baking experiment is carried out. The temperature data is gradually adjusted many times, and each time the temperature data is adjusted, a coating experiment is carried out. When the debugging coating layer is in the best state after the baking experiment, the temperature data t set in the reactor k This is the target data.

[0099] After finding the target data for the amount of resin raw materials, solvents, emulsifiers, wetting and dispersing agents, defoaming agents, and pigments added to the coating, the temperature control system gradually controls the temperature of the environment where the reactor is located. Under different temperature environments, the coatings processed according to the target data are monitored for performance. After performance monitoring, when the coating layer reaches the optimal state, the temperature data t set in the reactor k That is the target data. The debugging process of raw material addition ratio is independent of the temperature debugging process. In this method, the target data of each raw material is first found through the debugging system, and then the target data of the temperature of the coating processing environment is found through the gradual debugging of the temperature control system. During the coating debugging process, the adjustment direction of each parameter is relatively clear.

[0137] Step 2. Manually input the minimum amount of emulsifier added through the function window on the control panel 80 (the amount is determined based on the worker's experience, and ordinary coatings have basic reference standards, and the specific data are not disclosed). After the command is input, the first execution module 501 of the control system 50 controls the first metering pump 103 to open, and the first feed pipe 102 injects the emulsifier into the reactor 1 and continues to stir, and the first recording module 509 of the control system records the injected mass of the emulsifier as a;

[0138] Step 3. Manually input the minimum amount of wetting and dispersing agent added through the function window on the control panel 80.

[0141] Step 6. Fully stir and mix the resin raw material, solvent, emulsifier, wetting dispersant, defoamer and pigment in the reactor 1 to form a first debugging coating after mixing. Sample the first debugging coating and apply it on the sample 2. Observe the first debugging coating layer on the sample 2. After the observation is completed, record the situation. Drive the trolley to send the sample coated with the first debugging coating layer into the baking room 3 for baking experiment. The baking time is 5-10 hours. Then observe the appearance changes of the first debugging coating layer and record the changes.

[0142] Step 7. Analyze the changes of the first debugging coating layer fed back in step 6 one by one;

[0143] Step eight. If the first debugging coating layer is applied to the surface of the sample, the color depth of the coating layer does not meet the standard, the control system controls the fourth feeding mechanism 40 to intermittently inject pigment into the reactor 1, and the amount of pigment injected is recorded cumulatively, and the quality data recorded is d1, d2 ... dn;

[0144] Each time the pigment is injected, the reactor is fully stirred and the debug paint is exported. The exported debug paint is applied to a new sample and the color depth is observed. The pigment mass is gradually added many times. Each time the pigment is added, a coating experiment is performed until the color depth reaches the standard. The pigment mass data in the debug paint when the color depth reaches the standard is d k That is the target data;

[0145] Step 9. After the first debugging coating layer is coated on the surface of the sample, the sample coated with the first debugging coating layer is sent to the baking room 3 for baking experiment. If cracks appear on the surface of the first debugging coating layer, the control system controls the first feeding mechanism 10 to intermittently inject emulsifier into the reactor 1. The injection amount of the emulsifier is recorded cumulatively, and the recorded quality data is a1, a2…an;

[0146] Each time the emulsifier is injected, the reactor is fully stirred, and the debug coating is exported. The exported debug coating is coated on a new sample and a baking test is carried out. The emulsifier is added gradually for many times. Each time the emulsifier is added, a coating test is carried out until the debug coating layer does not crack after the baking test. The quality data of the emulsifier in the debug coating when it meets the standard is a k That is the target data;

[0147] Step 10. After the first debugging coating layer is coated on the surface of the sample, the sample coated with the first debugging coating layer is sent to the baking room 3 for baking experiment. If particle protrusions appear on the surface of the first debugging coating layer, the control system controls the second feeding mechanism 20 to intermittently inject the wetting and dispersing agent into the reactor 1. The injection amount of the wetting and dispersing agent is recorded cumulatively, and the recorded quality data is b1, b2...bn;

[0148] Each time the wetting and dispersing agent is injected, the reactor 1 is fully stirred, and the debug coating is exported. The exported debug coating is coated on a new sample 2 and a baking test is carried out. The wetting and dispersing agent is gradually added for many times. Each time the wetting and dispersing agent is added, a coating test is carried out until no particle protrusions appear in the debug coating layer after the baking test. The quality data of the wetting and dispersing agent in the debug coating when it meets the standard is b k That is the target data;

[0149] Step 11. After the first debugging coating layer is coated on the surface of the sample, the sample coated with the first debugging coating layer is sent to the baking room 3 for baking experiment. If there are pores in the cross section of the first debugging coating layer, the control system controls the third feeding mechanism 30 to intermittently inject defoaming agent into the reactor 1. When recording the injection amount of the defoaming agent, it is cumulatively recorded, and the recorded quality data is c1, c2...cn;

[0150] After each adjustment of the temperature data, the raw materials in the reactor 1 are fully stirred, that is, a debugging coating is exported, and the exported debugging coating is coated on a new sample 2 and a baking experiment is carried out. The temperature data is gradually adjusted many times, and each time the temperature data is adjusted, a coating experiment is carried out. When the debugging coating layer is in the best state after the baking experiment, the temperature data t set in the reactor k That is the target data;

[0151] Step 12. The data recorded by each recording module is stored by the logic processing unit 508, and the data recorded by the recording module is reset to zero. The raw materials in the reactor 1 are cleaned. After the cleaning is completed, the resin raw material with a mass of m is injected into the reactor again, and the solvent with a mass of n is injected at the same time. At the same time, according to the mass data a k Inject emulsifier, according to quality data b kInjection of wetting and dispersing additive, according to quality data c k Inject defoamer according to quality data d k Inject pigment, the data of each raw material is recorded by the corresponding recording module. After the raw material is injected, the temperature control module 507 of the temperature control system 60 controls the heating time of the electric heater 605, so as to control the temperature in the reactor 1. The thermometer 603 monitors the temperature environment of the reactor 1. The data of each temperature node are t1, t2...tn. The temperature data of each node can be set on the control panel. At the same time, the seventh recording module 515 records the specific values ​​of t1, t2...tn respectively.

[0152] After each adjustment of the temperature data, the raw materials in the reactor 1 are fully stirred, that is, a debugging coating is exported, and the exported debugging coating is coated on a new sample 2 and a baking experiment is carried out. The temperature data is gradually adjusted many times, and each time the temperature data is adjusted, a coating experiment is carried out. When the debugging coating layer is in the best state after the baking experiment, the temperature data t set in the reactor k That is the target data;

[0153] Step 13: After the control system 50 obtains the target data of each raw material and the target data of the temperature, the logic processing unit 508 integrates the target data and sends it to the background system for the background technicians to review and archive.

[0154] In summary, when debugging the formula of the coating, when a certain performance is unqualified, the corresponding raw materials are gradually added for the unqualified performance until the performance monitoring is qualified, and then the raw materials corresponding to another performance are gradually debugged, and the cycle is repeated until all the properties of the coating are qualified. This method monitors the properties of different raw materials one by one, and the monitoring purpose is strong. Moreover, the method of adding raw materials one by one can achieve high-precision adjustment of the raw material ratio;

[0155] This method uses the synchronous monitoring of the appearance and the use environment of the coating layer, which can not only conduct preliminary monitoring of the actual form of the coating, but also monitor the effect of the coating after use. This application combines the real-time performance monitoring of the coating with the coating debugging system, and reversely changes the addition amount of various raw materials in the coating according to the changes in various properties of the coating. The performance monitoring and debugging system of the coating complement each other, and the adjustment of the raw material addition amount is relatively clear;

[0156] The control system gradually controls the addition amount of emulsifiers, wetting and dispersing agents, defoaming agents and pigments. The cumulative addition amount of each raw material is recorded in real time by the corresponding recording module. When the addition amount of each raw material changes, the coating formula data in this case can be integrated and exported in time, making data integration convenient.
