Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof coiled material performance detection, and specifically relates to a device for detecting overflow and deformation of self-adhesive waterproof coiled materials due to their own weight under normal temperature and high temperature environment during storage. Background Art

[0002] Self-adhesive waterproofing membrane is a cylindrical roll-shaped flexible building product formed by winding a sheet on a reel. The thickness of the sheet varies from 1 to 4 mm and the length varies from 10 to 20 meters. The rolled waterproofing membrane generally has dozens of layers. Generally, "roll" is used as the quantity unit of self-adhesive waterproofing membrane, and the weight of each roll ranges from several kilograms to dozens of kilograms. For the self-adhesive waterproofing membrane 1' stored horizontally, the side of the membrane is in contact with the storage plane. In the warehouse, it is generally stacked in 5 layers (see Figure 1 ), during transportation, there may be more than 5 layers of stacking, and the bottom surface of the bottom roll bears the weight of itself and the rolls stacked above. The adhesive layer of the self-adhesive waterproof roll is a soft and sticky substance with creep characteristics and temperature sensitivity. Within a certain temperature range, as the temperature rises, its molecular movement intensifies and the properties become softer. Under the above background, during the hot summer climate, the adhesive layer of the bottom roll will be squeezed out or overflow under the heavy pressure, resulting in the thickness of the adhesive of the bottom roll becoming thinner. The adhesion between the flattened and thinned adhesive layer and the base surface is reduced, and it may even result in the inability to bond. At the same time, the overflowing adhesive layer will also contaminate the surface of the roll. The existing standards and testing devices mainly test the high-temperature slip resistance, oil seepage, mechanics and dimensional changes of the main reinforcement layer of the self-adhesive waterproof membrane adhesive layer. There are no national, industry or group standards that require the overflow and deformation of the adhesive layer when the self-adhesive waterproof membrane is stored horizontally. There is also no corresponding device on the market to detect this phenomenon. Therefore, it is necessary to develop a device to measure the storage deformation of waterproof membranes. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a device for detecting the storage deformation of waterproof coiled materials, so as to fill the current gap in detecting the overflow and deformation state of waterproof coiled materials during storage.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A device for detecting storage deformation of waterproof coiled materials comprises a box body and a measuring system, a temperature control system and a monitoring and recording system installed in the box body; the measuring system comprises a load-bearing platform for holding a test piece, a support frame for pressing down the test piece and a pressure rod for applying pressure to the support frame.

[0006] The load-bearing platform is a metal dial arranged horizontally on the bottom plane of the box body, the surface of the metal dial has scales, and a pressure sensor and a pressure display gauge that can display the pressure value are installed below the load-bearing platform.

[0007] The structure of the support frame is a hard transparent high-temperature resistant plastic plate supported above the load-bearing platform by support rods at four corners. A spring is provided on each metal support rod. When in a non-stressed state, the transparent high-temperature resistant plastic plate maintains a reserved spacing with the load-bearing platform for loading and unloading specimens under the action of the spring.

[0008] The pressure rod includes a sleeve fixed to the top surface of the box body and opened up and down, and a rod member inserted in the middle of the sleeve and movable up and down. A spring is sleeved on the lower half of the rod member. Two discs are respectively connected to the upper and lower ends of the rod member. The diameters of the upper disc and the lower disc are larger than the opening diameter of the sleeve. The upper disc is used to place weights of different weights for counterweighting. The counterweighted rod member can overcome the action of the spring and be pressed downward under the action of gravity. A vertical electronic ruler is installed on one side of the pressure rod, and a stroke adjustment display meter for recording and displaying the downward stroke is installed under the box body.

[0009] The temperature control system includes a heater, a temperature sensor and a temperature adjustment controller. The heater is arranged on the side walls on the left and right sides of the box, one temperature sensor is installed on the top of the box, and the other temperature sensor is installed under the load-bearing platform.

[0011] After adopting the above technical solution, the utility model has the following advantages compared with the background technology:

[0012] 1. The utility model provides a detection device for the research and development of waterproof roll products. R&D personnel can test the storage deformation of waterproof rolls, especially in high temperature seasons, in the laboratory stage. It does not need to consume too much manpower and materials to simulate and observe the phenomenon of changes in the storage of rolls on site. It only needs to take partial samples in proportion and apply a fixed or 1 / 10 or even lower gravity of the total weight of the rolls. The deformation of the rolls after being compressed can be detected in the laboratory. It can provide a basis for material selection and formula debugging in the product development stage, optimize functions and costs through data, and can also test the storage performance of products before leaving the factory. It can also provide the optimal quantity selection for product storage and transportation deployment. The detection device can adopt a box structure, which is easy to carry and place, and simple to operate.

[0013] 2. The detection device of the utility model is the first to be developed in the waterproofing membrane industry, filling the gap in the device for detecting deformations such as overflow and deformation during the storage of self-adhesive waterproofing membranes. The detection device has multiple functions such as heating and temperature control, pressure sensing, stroke measurement, and image recording. The operation process is simple and intuitive, eliminating the need to simulate and observe the changes in the storage of membranes on site, saving manpower and material resources. At the same time, an image monitoring and recording system is used to record the detection process, and the deformation trend of the product can be predicted through accelerated thermal aging analysis. The detection data plays an important reference and guiding role in product development, material selection, storage and transportation. The detection device of the utility model shortens the research and development and testing cycle of waterproofing membrane products, reduces research and development costs by screening formulas, and provides a basis for the selection of raw materials for products. At the same time, detecting the limit deformation of the membrane storage can provide a basis for product stacking, making full use of space to save storage costs and ensure that the product quality is in a high-quality state.

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] Example

[0021] See also Figure 2 to Figure 5 As shown, the utility model discloses a storage deformation detection device for waterproof coiled material, which comprises a box body 1 and a measuring system, a temperature control system and a monitoring and recording system installed in the box body 1.

[0022] An observation window 14 is provided on the door of the box 1, and adjustable feet 11 are respectively installed at the four corners of the bottom of the box 1. A level 12 is installed on the horizontal surface in the box. The adjustable feet 11 are adjusted by observing the level 12 to keep the box level, thereby avoiding measurement errors caused by the specimen having a single direction trend due to non-levelness.

[0023] The measuring system includes a load-bearing platform 21 for holding the specimen, a support frame 32 for pressing the specimen, and a pressure rod for applying pressure. The load-bearing platform 21 is installed on the bottom plane of the box. The load-bearing platform 21 is a horizontally arranged metal dial. The metal dial is used to hold the specimen, and the scale on the surface is convenient for measuring the deformation of the specimen. A pressure sensor is installed below the load-bearing platform 21 to sense the pressure on the upper specimen and display the pressure value through the pressure display meter 22 below.

[0024] A support frame 32 is installed above the load-bearing platform 21. The structure of the support frame 32 is a transparent high-temperature resistant plastic plate 33 with a certain hardness, which is supported above the load-bearing platform 21 by support rods 34 at four corners. A spring 35 is provided on each metal support rod 34. When in a non-stressed state, the transparent high-temperature resistant plastic plate 33 maintains a distance of about 5 cm from the load-bearing platform 21 under the action of the spring. This distance is a reserved space for loading and unloading test pieces.

[0025] A pressure rod is installed on the top of the box body 1. Figure 5 As shown, the pressure rod includes a sleeve 41 fixed to the top surface of the box body and opened up and down, and a rod 42 that is inserted in the middle of the sleeve 41 and can move up and down. The upper and lower thicknesses of the rod 42 are inconsistent. A spring 43 is sleeved on the lower half of the rod 42. The upper and lower ends of the rod 42 are respectively connected with two large and small disks by threads. The diameters of the upper disk 44 and the lower disk 45 are larger than the opening diameter of the sleeve, and the area of ​​the upper disk 44 is larger, which is convenient for placing weights of different weights on the upper disk 44 for counterweighting. The counterweighted rod 42 can overcome the spring action and be pressed downward under the action of gravity. A vertical electronic ruler 46 is installed on one side of the pressure rod, and a stroke adjustment display meter 47 under the box body is used to record and display the downward stroke when subjected to force.

[0026] When testing, the test piece is placed on the load-bearing platform 21, and weights or forces are piled on the upper disc 44. The weighted pressure rod overcomes the elastic force of the spring 43 and extends downward, and the lower disc 45 is pressed on the transparent high-temperature resistant plastic plate 33. The pressed transparent high-temperature resistant plastic plate 33 overcomes the resistance of the spring 35 and is pressed on the surface of the test piece, and the gravity is evenly distributed on the test piece. The scale on the load-bearing platform 21 can measure the deformation amount of the test piece and the overflow amount of the adhesive layer very intuitively and conveniently.

[0027] The box is also provided with a temperature control system, which includes a heater 51, temperature sensors 52, 54 and a temperature control controller 53. The heater 51 can be an electric furnace wire, which is arranged on the side walls on the left and right sides of the box 1. Figure 2 As shown, the side walls on the left and right sides of the box body 1 are provided with an insulating layer 13 made of asbestos, a heater 51 and a metal partition 15 in sequence from the outside to the inside.

[0028] One of the temperature sensors 52 is installed on the top of the box 1, which is used to sense the air temperature in the box and feed back the signal to the temperature control controller. Another temperature sensor 54 is installed below the load-bearing platform 21, and the temperature of the test piece is detected by the metal dial, and the signal is fed back to the temperature control controller. The required temperature can be set on the temperature control controller, and the heater 51 is controlled to heat to the specified temperature. The heated air is transported to the box through the metal partition 15 for circulation under the action of the blower (not shown). The temperature sensor senses the temperature in the box and feeds back the signal to the temperature control controller. The display screen 53 below can also display the real-time temperature in the box and the surface temperature of the load-bearing platform. The temperature control system has the functions of heating, temperature control, constant temperature, and monitoring the temperature of the load-bearing platform, and can simulate different step temperature detections.

[0029] The utility model is also provided with a monitoring and recording system, which includes a camera 61 and an illuminator 63 installed on the top surface of the box body, which are used for shooting, recording and increasing the brightness during the detection process. The diagonally inclined lens has a more comprehensive coverage range, and a camera display 62 is also provided at the bottom of the box body.

[0030] The utility model obtains data on overflow and deformation of the rubber layer by testing small test pieces of self-adhesive waterproofing membranes. First, three small samples of 4cm×4cm in size are pre-taken from 1.8mm thick self-adhesive waterproofing membranes made of three different formulas A, B, and C as test pieces for testing. The size of the test piece needs to be larger than the diameter of the lower disc, and the pressure that the test piece is preset to bear is 10.0N. Before testing, two transparent films are placed on the upper and lower surfaces of the test piece respectively to prevent the test piece from overflowing and contaminating the device. Then the test piece is placed at the center of the load-bearing platform 21, the temperature is adjusted to 60°C, and the box door is closed to maintain a constant temperature. The upper disc 44 of the pressure rod is stacked with weights or the force is increased at a uniform speed, so that the pressure rod can overcome the spring resistance and extend downward under the action of external force, and the lower disc 45 is pressed down on the transparent high-temperature resistant plastic plate 33. From the observation window, it can be seen that the transparent high-temperature resistant plastic plate 33 touches the test piece. When the value of the pressure display meter 22 shows 10.0N, stop stacking weights or increasing force, return the electronic ruler 46 to zero, and start the camera to record. The deformation amount in the constant temperature environment for 1h to 5h is obtained through recording:

[0031] The specimen of formula A overflowed 0.1mm in 1h and had a stroke of 0.13mm. The adhesive layer overflowed 0.6mm in 2h and had a stroke of 0.22mm. The adhesive layer overflowed 2.8mm in 5h and had a stroke of 0.48mm.

[0032] The specimen of formula B overflowed 0.1mm in 1h and had a stroke of 0.21mm. The adhesive layer overflowed 1.25mm in 2h and had a stroke of 0.33mm. The adhesive layer overflowed 4.2mm in 5h and had a stroke of 0.67mm.

[0033] The specimen with formulation C had an overspread of 0.2mm and a stroke of 0.29mm in 1h, an overspread of 1.54mm and a stroke of 0.53mm in 2h, and an overspread of 5.6mm and a stroke of 0.91mm in 5h.

[0034] Through data screening, the deformation of the specimen with formula A is the smallest, and formula A is preferred.

[0035] The utility model can also detect the deformation of coils when the coils are in the hot climate of July in summer, and the coils are placed in a closed space of a container in multiple layers. The maximum temperature in the container is 65°C, the coil thickness is 1.5mm, the weight of each coil is 40kg, 5 layers of coils are stacked, the total bearing capacity of the adhesive layer of the bottom layer of coils in contact with the plane is 200kg, the side dimensions of the coils in a horizontal position (the area in contact with the ground or plane) are 100cm×12cm (length×width), and the pressure per unit area of ​​the bottom coil is calculated to be 200×9.8÷1200=1.63N / cm 2 , pre-take a 5cm×5cm (length×width) coil as a test specimen, and calculate the actual pressure the specimen bears to be 16.3×25 (specimen size)=40.75N. Before testing, place two transparent films on the upper and lower surfaces of the specimen respectively to prevent the specimen from overflowing and contaminating the device. Then put the specimen on the load-bearing platform, adjust the device to a constant temperature of 65°C, and close the device door. On the pressure rod, stack weights on the disc 44 or increase the force at a uniform speed. When the indication of the pressure display table 22 shows 40.75N, stop stacking weights or increasing the force, return the electronic ruler 46 to zero, and start video recording. The deformation amount at constant temperature for 1h to 8h was obtained through recording:

[0036] The adhesive layer of the test piece overflowed 2mm and the stroke was 0.32mm in 1h, 3.2mm and 0.42mm in 2h, 4.1mm and 0.53mm in 3h…, 6.9mm and 0.81mm in 8h. The test results met the internal indicators: adhesive layer overflow ≤8.0mm and ≤1.0mm in 8h.

[0037] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
