Description
Technical Field
The invention belongs to the technical field of aging tests, and particularly relates to an aging test device for a macromolecular elastomer coating protection system for simulating the actual environment of a hydraulic building.
Background
Seepage prevention measures for hydraulic engineering have been the focus of attention of researchers and designers. Test and monitoring data show that the water pressure promotes the micro-crack expansion of the hydraulic structure under the limit working condition due to the reasons of uniform settlement of the foundation, temperature effect and the like, and further generates direct threat to the stability of the structure. The cracks of the water conveyance building which are contacted with water all the year round have the characteristics of high inspection difficulty, difficult repair and the like, so in order to reduce the damage caused by leakage and improve the durability and the safety of the structure, effective engineering anti-seepage measures are necessary to be taken before water flows through the water conveyance building or during the maintenance period of the water conveyance building. The macromolecule elastomer based on the reaction spray molding technology, in particular to the polyurea elastic coating, has excellent corrosion resistance, hydrolysis resistance and freeze-thaw resistance, has good mechanical property, and can be widely applied to the seepage-proofing field of hydraulic buildings as a concrete durability protective coating material. However, investigation shows that in practical application, the polyurea impermeable protective elastomer coating of some hydraulic and hydroelectric engineering has different aging and deterioration phenomena of damage, performance reduction, breakage, shedding, hydrolysis, peeling, swelling, pulverization and the like during operation, and can not meet the requirement of durability specified by design. This indicates that the mechanical properties of the polyurea material exposed to the hydraulic environment are gradually aged by light, heat and moisture during the operation of the structure, and the time for the coating to maintain effective mechanical properties is closely related to the durability of the structure, so that the durability and life prediction of the polyurea material are receiving more and more attention from researchers.
The method is characterized in that the conventional durability test method and durability damage failure mode of the polymer coating and system aged by heat, oxygen and ultraviolet rays are simply used, critical parameters and critical values for initiating the anti-seepage protective coating and the aging damage of the system are enabled to be not in accordance with the damage failure rule of the polyurea anti-seepage system in the water-immersed environment, the dry-wet alternate environment, the water pressure action and the water flow scouring environment of the hydraulic building to a great extent, and the service life prediction model can not truly reflect the actual conditions of the environments. Therefore, from an objective perspective, the durability research of the polyurea anti-seepage system is required to be established on the basis of an aging acceleration test method adaptive to the use environment and a damage failure mode thereof, so that the actual condition can be approached, the service life prediction of the polyurea anti-seepage system can be accurate and effective, and the durability design of the anti-seepage protection structure of the hydraulic building can be realized according to the specified service life.
At present, most of polymer aging test devices are constant temperature aging boxes based on thermal oxidation aging (patent 201710619299.2, a device for testing the cracking resistance of rubber materials), or light aging boxes based on ultraviolet aging (patent 201720819057.3, an ultraviolet aging test box), or water bath constant temperature aging boxes based on water spraying environment aging) patent 201810839495.5, and a high-low temperature aging box with a spraying device. The above-described device has the following disadvantages in practical use:
(1) the number of test samples of the disposable device is small, and the disposable device cannot be suitable for test pieces with multiple sizes;
(2) cannot bear water pressure;
(3) the dry-wet alternation test cannot be carried out;
(4) the test under the action of high-speed water flow cannot be carried out;
(5) the test device is complex;
(6) the test efficiency is low;
(7) the device cost is high;
(8) the rapid accelerated aging test cannot be carried out on the test material, so that the test time is long, and the test result is difficult to visually show.

This ageing kettle 1 includes cylindric cauldron body 11, and this cauldron body 11 top is equipped with opening 12, and the diameter of this cauldron body 11 lateral wall top to this opening periphery reduces gradually, forms neck 13. The opening 12 is closed by a detachable top cover 14, the neck 13 is provided with an operation opening 15, and the operation opening 15 is closed by a sealing cover 16. The kettle body 11 is provided with a temperature control device and a pressure control device, so that the kettle has the heating and pressurizing functions. The temperature control device may be a jacket disposed on the sidewall of the kettle 11, and the pressure control device may be a pressurized air pump connected to the kettle 11.
The rotating structure 2 is located at the bottom of the kettle 11 and includes a rotating shaft 21 penetrating the middle of the upper cover 14, and the top of the rotating shaft 21 is located above the upper cover 14 and connected to a driving shaft 31 of the driving motor 3, and can rotate and move up and down synchronously with the driving shaft 31. The side of the aging kettle is provided with a mounting rack, and the driving motor 3 is fixed on the mounting rack. The bottom of the rotating shaft 21 is sequentially sleeved with a top plate 22 and a bottom plate 23 which are parallel, and the top plate 22 and the bottom plate 23 can rotate synchronously with the rotating shaft 21. The part of the rotating shaft 21 between the top plate 22 and the bottom plate 23 is sleeved with a shaft sleeve 211, the side surface of the shaft sleeve 211 is provided with a guide groove 212, and the guide groove 212 is vertical or forms an acute angle with the vertical direction. The shaft 213 extends outwards from the rotating shaft 21 corresponding to the circumference of the guide groove 212, and the shaft 213 is located in the guide groove 212 and has a distal end connected to the support rod 26 via a universal joint. A plurality of support columns 24 are disposed between the edges of the top plate 22 and the bottom plate 23, two support columns 24 are symmetrically disposed in the embodiment.

The end of the supporting rod 26 is connected to the outer end of the specimen holder 25 through a universal joint, and when the rotating shaft 21 moves from top to bottom, the shaft rod 213 drives the supporting rod 26 to push the specimen holder 25 outward, so that the specimen holder is unfolded to the unfolded position; on the contrary, when the rotating shaft 21 moves from bottom to top, the shaft 213 drives the supporting rod 26 to pull the specimen holder 25 inward, so that it is retracted to the folded position. The specimen holder 25 is in a grid shape to reduce fluid resistance, and is provided with a plurality of specimen holders 27 for holding specimens. Specifically, the test piece holder 25 has a rectangular longitudinal section and a cross section in a shape of a straight line, and is provided with a plurality of vertical columns 251 inside, and the test piece holder 27 is fixed on the side surfaces of the columns 251.

Conversely, when the specimen holder 25 needs to be retracted, the rotation shaft 21 is simply pulled upward to move the shaft 213 upward. Further, the bottom of the bottom plate 23 is provided with a conical stabilizing device 231, and the bottom end of the stabilizing device 231 is provided with a ball 232 for reducing the rotating friction on the bottom of the aging kettle. When the test piece rack 25 is subjected to force spreading, the sphere 232 is in contact with the bottom of the kettle body 11 of the aging kettle 1.
