Description

Technical Field

[0001] The invention relates to the field of waterproof coiled material processing, in particular to a base oiling device and an oiling method for a modified asphalt waterproof coiled material. Background Art

[0002] When making modified asphalt waterproofing membranes, base and modified asphalt are used. During processing, the modified asphalt needs to be coated on the surface of the base, and then it is subjected to processes such as lamination and embossing to finally prepare the corresponding waterproofing membrane products. In the prior art, soaking the base with modified asphalt is very simple, that is, the base is sent into the asphalt pool so that its surface is soaked with modified asphalt. Such a process is simple, but for those who want to produce waterproofing membranes with better quality, such soaking and covering are not enough, because a single modified asphalt adheres to the surface of the base and there will be more or less certain defects. The prior art generally improves the base as much as possible through modification. There is a way to improve this defect, but there is a method that can skip the complicated modification process, and the performance of the modified asphalt waterproof membrane produced may be better than the further modified asphalt waterproof membrane. This method is to coat two complementary modified asphalts in layers on the surface of the base. At present, this method has not been seen. In order to use this method to make modified asphalt waterproof membranes, it is necessary to transform the existing production line of modified asphalt waterproof membranes. For this reason, this scheme proposes a base oil immersion device for modified asphalt waterproof membranes that can adapt to this method and a method for oil immersion using the same. Summary of the invention

[0003] The purpose of the present invention is to provide a modified asphalt waterproofing membrane base oiling device and oiling method to solve the problem that the existing modified asphalt waterproofing membrane base oiling device cannot complete the processing of covering the base surface with two different modified asphalts.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: A base oiling device for a modified asphalt waterproofing coiled material comprises a pre-impregnation tank and a main impregnation tank which are arranged in sequence, the asphalt input ports of the pre-impregnation tank and the main impregnation tank being connected to a first modified asphalt storage tank and a second modified asphalt storage tank respectively, the pre-impregnation tank and the main impregnation tank being arranged in a pre-impregnation box and a main impregnation box respectively, the pre-impregnation box and the main impregnation box being connected through a material transfer channel, spraying mechanisms being evenly arranged in the material transfer channel, the pre-impregnation tank and the main impregnation tank being both provided with a limiting roller type cloth feeding mechanism, a base heating roller being provided at the feed port of the pre-impregnation tank, the discharge end of the base heating roller being connected to the feed end of the limiting roller type cloth feeding mechanism in the pre-impregnation tank, and the discharge ends of the pre-impregnation tank and the main impregnation tank being provided with a redundant asphalt scraping mechanism.

[0005] The prepared tire base is sent to the pre-impregnation tank for pre-impregnation. The tire base needs to be heated before pre-impregnation. After the immersion is completed, the initial coating of modified asphalt in the No. 1 modified asphalt storage tank is coated on both sides. The excess asphalt is scraped off by the excess asphalt scraping mechanism in the pre-impregnation tank and then sent to the material transfer channel. When the initial coating passes through the material transfer channel, the spraying mechanism will selectively spray the compatibilizer according to the modified asphalt in the No. 1 modified asphalt storage tank and the modified asphalt in the No. 2 modified asphalt storage tank. After the initial coating passes through the material transfer channel, it enters the main immersion tank for secondary modified asphalt immersion. The secondary modified asphalt immersion After the soaking is completed, the excess asphalt scraping mechanism of the main immersion tank is used to scrape off the excess modified asphalt to complete the immersion of the tire base. In this way, two complementary modified asphalts can be coated on the surface of the tire base, so that it can achieve performance that ordinary waterproof membranes cannot achieve. The reason why excess asphalt scraping mechanisms are set at the discharge ends of the pre-immersion tank and the main immersion tank is because they themselves have to be coated with two layers of modified asphalt, so their thickness must be strictly controlled. The main purpose of heating the tire base before pre-immersion is to fully discharge the moisture in the tire base through heating, and to make the adhesion effect between the tire base and the modified asphalt better.

[0006] As a further preferred embodiment of the present invention, a prepreg box body temperature control system and a main impregnation box body temperature control system are respectively provided in the prepreg box body and the main impregnation box body.

[0007] Because different modified asphalts require different temperatures to achieve the best adhesion effect, a pre-impregnation box temperature control system and a main impregnation box temperature control system are set up here. By adjusting the temperature separately, the best adhesion effect can be achieved regardless of whether it is during pre-impregnation or main impregnation.

[0008] As a further preferred embodiment of the present invention, the spray head of the spraying mechanism is connected to the spraying tank through a pumping pipeline.

[0009] Common types of modified asphalt include SBS modified asphalt, SBR modified asphalt, APP modified asphalt, PE modified asphalt and PA modified asphalt. When different types of modified asphalt are mixed, compatibility and mixing ratio need to be considered, because different modified asphalts may repel or split each other. For example, when SBR modified asphalt and SBS modified asphalt are mixed, corresponding compatibilizers need to be selected to ensure that the mixed modified asphalt can meet the expected performance requirements. Therefore, the nozzle of the spraying mechanism can spray the corresponding preparation on the surface of the pre-impregnated modified asphalt after pre-impregnation, so that the material can be well coated with the second modified asphalt after entering the main immersion tank, so that the two modified asphalts can be more harmoniously integrated and used to form complementary performance. The feed channel and the spraying mechanism structure in the feed channel are necessary for the production of this mixed modified asphalt waterproof membrane, and are also unique to it.

[0010] As a further preferred embodiment of the present invention, the spray tank is provided with an electric heating mechanism.

[0011] The temperature of the sprayed preparation can be controlled, which is more conducive to its rapid combination reaction with modified asphalt.

[0012] As a further preferred embodiment of the present invention, a deviation correction mechanism is provided between the tire base heating roller and the limiting roller type cloth feeding mechanism in the prepreg tank and at the discharge port of the material transfer channel.

[0013] It can correct the deviation during production, because sometimes the tire base may shift during movement, and it needs to be corrected to ensure quality. The reason why the correction mechanism is set between the tire base heating roller and the limiting roller feeding mechanism in the pre-impregnation tank is because the correction before pre-impregnation is the most timely, and then a correction mechanism is also set at the discharge port of the feed channel. One is to enable more precise control during the main immersion, and the other is because the discharge port of the feed channel is far away from the pre-impregnation tank. At this time, the asphalt in the pre-impregnation tank has been relatively stably attached to the tire base surface, and it is not easy for the modified asphalt in the pre-impregnation tank to be rubbed off the tire base due to the correction mechanism.

[0014] As a further preferred embodiment of the present invention, the correcting mechanism includes a main support roller and a correcting roller. The correcting roller is obliquely arranged at the two ends of the main support roller, and the correcting roller is inclined upward from the inside to the outside. The two ends of the rotating shaft of the correcting roller are connected to the correcting roller base through a rotating seat, one end of the correcting roller base is rotatably connected to the fixed surface of the correcting mechanism, and the bottom surface of the other end of the correcting seat is hinged to the top of the telescopic rod of the hydraulic cylinder, and the hydraulic cylinder is hinged to the fixed surface of the correcting mechanism.

[0015] The inclination angle of the deviation correction roller can be adjusted through the telescopic rod of the hydraulic cylinder, so that it can better adapt to the tire base and better complete the deviation correction work.

[0016] As a further preferred embodiment of the present invention, the excess asphalt scraping mechanism includes an extrusion scraping roller and a scraping roller cleaning mechanism, the extrusion scraping roller includes an upper movable extrusion roller and a lower fixed extrusion roller, the upper movable extrusion roller can move in a vertical direction, and an excess asphalt scraping channel is left between the upper movable extrusion roller and the lower fixed extrusion roller, the scraping roller cleaning mechanism includes an upper cleaning rubber scraper and a lower cleaning rubber scraper, and the upper cleaning rubber scraper and the lower cleaning rubber scraper are respectively arranged close to the upper movable extrusion roller and the lower fixed extrusion roller.

[0017] The scraping thickness can be adjusted by adjusting the distance between the upper movable squeezing roller and the lower fixed squeezing roller, and the upper cleaning rubber scraper and the lower cleaning rubber scraper can keep the surfaces of the upper movable squeezing roller and the lower fixed squeezing roller clean.

[0018] As a further preferred embodiment of the present invention, the material transfer channel is "U"-shaped, and guide rollers are provided at the turning points in the middle of the material transfer channel.

[0019] The "U"-shaped material transfer channel not only serves to isolate the heat transfer between the prepreg box and the main prepreg box, but also avoids the problem that when feeding horizontally, the preparation sprayed by the spraying mechanism at the bottom cannot be well combined with the modified asphalt due to the effect of gravity. The material transfer channel adopts a "U"-shaped structure, so during transportation, the tire base is in a vertical state most of the time. At this time, the spraying mechanism is located on both sides of the material, and the sprayed preparation can be well combined with the modified asphalt on the surface of the material.

[0020] The method for oiling the base of the modified asphalt waterproofing membrane described in any one of the above-mentioned items comprises the following steps: A. sending the prepared base to a pre-impregnation tank for pre-impregnation, and the base needs to be heated before pre-impregnation; B. after the immersion is completed, the initial coating of the modified asphalt in the No. 1 modified asphalt storage tank is coated on both sides, and the excess asphalt is scraped off by the excess asphalt scraping mechanism in the pre-impregnation tank, and then sent to the material transfer channel. When the initial coating passes through the material transfer channel, the spraying mechanism will selectively spray the compatibilizer according to the modified asphalt in the No. 1 modified asphalt storage tank and the modified asphalt in the No. 2 modified asphalt storage tank; C. After the initial coating passes through the material transfer channel, it enters the main immersion tank for secondary modified asphalt immersion. After the secondary modified asphalt immersion is completed, the excess modified asphalt is scraped off by the excess asphalt scraping mechanism in the main immersion tank to complete the base immersion work.

[0021] It is a new method for producing modified asphalt waterproofing membrane. The modified asphalt waterproofing membrane produced by this method does not require excessive modification of the asphalt, is simpler, and uses improved production equipment for production. The modified asphalt waterproofing membrane produced is of high quality and good performance.

[0022] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. Send the prepared tire base into the pre-impregnation tank for pre-impregnation. The tire base needs to be heated before pre-impregnation. After the immersion is completed, the initial coating of modified asphalt in the No. 1 modified asphalt storage tank is coated on both sides. The excess asphalt is scraped off by the excess asphalt scraping mechanism in the pre-impregnation tank and then sent to the material transfer channel. When the initial coating passes through the material transfer channel, the spraying mechanism will selectively spray the compatibilizer according to the modified asphalt in the No. 1 modified asphalt storage tank and the modified asphalt in the No. 2 modified asphalt storage tank. After the initial coating passes through the material transfer channel, it enters the main immersion tank for secondary modified asphalt immersion. The secondary modified asphalt After the soaking is completed, the excess asphalt scraping mechanism of the main soaking tank is used to scrape off the excess modified asphalt to complete the tire base soaking work. In this way, two complementary modified asphalts can be coated on the tire base surface, so that it can achieve performance that ordinary waterproof membranes cannot achieve. The reason why excess asphalt scraping mechanisms are set at the discharge ends of the pre-immersion tank and the main soaking tank is because they themselves have to be coated with two layers of modified asphalt, so their thickness must be strictly controlled. The main purpose of heating the tire base before pre-immersion is to fully discharge the moisture in the tire base through heating, and to make the adhesion effect between the tire base and the modified asphalt better.

[0023] 2. Because different modified asphalts require different temperatures to achieve the best adhesion effect, a pre-impregnation box temperature control system and a main impregnation box temperature control system are set up here. By adjusting the temperature separately, the best adhesion effect can be achieved regardless of whether it is during pre-impregnation or main impregnation.

[0024] 3. The temperature of the sprayed preparation can be controlled, which is more conducive to its rapid combination reaction with modified asphalt.

[0025] 4. It can correct the deviation during production, because sometimes the tire base may shift during movement. In order to ensure quality, it needs to be corrected. The reason why the correction mechanism is set between the tire base heating roller and the limiting roller feeding mechanism in the pre-impregnation tank is because the correction before pre-impregnation is the most timely. Then a correction mechanism is also set at the discharge port of the feed channel. One is to enable more precise control during the main immersion, and the other is because the discharge port of the feed channel is far away from the pre-impregnation tank. At this time, the asphalt in the pre-impregnation tank has been relatively stably attached to the tire base surface, and it is not easy to rub the modified asphalt in the pre-impregnation tank off the tire base due to the correction mechanism.

[0026] 5. The inclination angle of the correction roller can be adjusted through the telescopic rod of the hydraulic cylinder, which can better adapt to the tire base and better complete the correction work.

[0027] 6. The scraping thickness can be adjusted by adjusting the distance between the upper movable squeezing roller and the lower fixed squeezing roller. The upper cleaning rubber scraper and the lower cleaning rubber scraper can keep the surface of the upper movable squeezing roller and the lower fixed squeezing roller clean.

[0028] 7. The U-shaped material transfer channel not only isolates the heat transfer between the prepreg box and the main impregnation box, but also avoids the problem that when feeding horizontally, the preparation sprayed by the spraying mechanism at the bottom cannot be well combined with the modified asphalt due to gravity. The material transfer channel adopts a "U"-shaped structure, so during transportation, the tire base is in a vertical state most of the time. At this time, the spraying mechanism is located on both sides of the material, and the sprayed preparation can be well combined with the modified asphalt on the surface of the material.

[0029] 8. It is a new method for producing modified asphalt waterproofing membrane. The modified asphalt waterproofing membrane produced by this method does not need to modify the asphalt excessively, which is simpler. In addition, it uses improved production equipment for production. The modified asphalt waterproofing membrane produced is of high quality and good performance. BRIEF DESCRIPTION OF THE DRAWINGS

After the initial coating passes through the material transfer channel, it enters the main immersion tank for secondary modified asphalt immersion. The secondary modified asphalt immersion After the soaking is completed, the excess asphalt scraping mechanism of the main immersion tank is used to scrape off the excess modified asphalt to complete the immersion of the tire base. In this way, two complementary modified asphalts can be coated on the surface of the tire base, so that it can achieve performance that ordinary waterproof membranes cannot achieve. The reason why excess asphalt scraping mechanisms are set at the discharge ends of the pre-immersion tank and the main immersion tank is because they themselves have to be coated with two layers of modified asphalt, so their thickness must be strictly controlled. The main purpose of heating the tire base before pre-immersion is to fully discharge the moisture in the tire base through heating, and to make the adhesion effect between the tire base and the modified asphalt better.

[0042] Because different modified asphalts require different temperatures to achieve the best adhesion effect, a pre-impregnation box temperature control system and a main impregnation box temperature control system are set up here. By adjusting the temperature separately, the best adhesion effect can be achieved regardless of whether it is during pre-impregnation or main impregnation. Specific embodiment 3: This embodiment further illustrates the spraying mechanism on the basis of the specific embodiment 1. The spray head of the spraying mechanism 6 is connected to the spraying tank through a pumping pipeline.

[0044] Common types of modified asphalt include SBS modified asphalt, SBR modified asphalt, APP modified asphalt, PE modified asphalt and PA modified asphalt.

For example, when SBR modified asphalt and SBS modified asphalt are mixed, corresponding compatibilizers need to be selected to ensure that the mixed modified asphalt can meet the expected performance requirements.

A correction mechanism 9 is provided between the tire base heating roller 7 and the limiting roller type cloth feeding mechanism in the prepreg tank 1 and at the discharge port of the material transfer channel 5.

[0048] It can correct the deviation during production, because sometimes the tire base may shift during movement, and it needs to be corrected to ensure quality.
