The invention provides a waterproof sealing adhesive tape and the preparation method thereof, which relates to the technology field of the waterproof sealing adhesive tape and the preparation thereof. The waterproof sealing adhesive tape is composed of a waterproof sealing layer and two pieces of adhesive-proof oil paper attached to the both sides of the waterproof sealing layer, the waterproof sealing layer and the two pieces of adhesive-proof oil paper are produced through calendering and compounding, the waterproof sealing layer comprises the following components and contents (by weight): 100 parts of butyl rubber, 60 to 80 parts of silicon dioxide, 8 to 25 parts of polyolefine, and 70 to 120 parts of tackifier. The waterproof sealing adhesive tape has the raw materials which are easy to be acquired, low in cost and suitable for the industrialized production, the performance index thereof can fully exceed the technical level of the similar domestic products, the product has high tensile strength and peeling strength and good high and low temperature resistant performances, and can still play the role of waterproof sealing under the high temperature of 90 DEG C and the low temperature of minus 40 DEG C and under the pressure of 0.08 MPA.

The invention discloses an air conditioner and blower fan assembly bearing cap waterproof sealing structure thereof, for solving the problem of water penetration in a bearing chamber. By using the air conditioner and the blower fan assembly bearing cap waterproof sealing structure thereof, even if water is accumulated at a bearing cap, under the sealing effect of a double-layer O-shaped ring, the waterproof effect is exhibited, it is ensured that the inside of the bearing chamber is dry and dustproof, bearings can be prevented from being rusted, the reliability of the bearings is improved, and the operation safety and reliability of a modular dynamo-electric machine are improved; besides, clamps are arranged at the inner layer of the bearing cap, clamping grooves are arranged at the inner circular surface of a motor end cap, and when the bearing cap is forcefully pressed downwards, the clamps and the clamping grooves closely cooperate with each other, and thus a conventional screw screwing mode is replaced; and such a design of the bearing cap and the clamps replaces a bolt pretightening design, arrangement of a tightening moment is unnecessary, boring and tapping at the end cap are unnecessary, anti-loosening measures are reduced, the assembling is simpler and more reliable, and the man hours are greatly reduced.

The invention discloses a multifunctional towel rack, which belongs to the technical field of towel racks. The invention is provided with a disinfection rack body and a drying rack body. The disinfection rack body and the drying rack body respectively have the functions of sterilization, heating and drying, greatly improving The functionality of the towel rack is enhanced, and through the setting of the drying rack body, after the wet towel is placed on the drying rack tube, the intelligent controller can not only automatically start the carbon fiber electric heating tube to heat and dry the towel, but also After the towel is dried, the carbon fiber electric heating tube can be automatically turned off, so that the carbon fiber electric heating tube can be automatically turned on and off, which improves the convenience, and the towel after drying is not easy to fall off, which improves the practicability. The setting enables the user to independently select the installation sequence and quantity of the disinfection rack body and the drying rack body according to their own needs, which significantly reduces the limitation of the towel rack and further improves the practicability of the towel rack.

The invention discloses a sheet pile supporting structure with a water stopping function and a construction method. The sheet pile supporting structure with the water stopping function and the construction method are used for soil blocking and water stopping of the circumferential wall of a foundation pit. The sheet pile supporting structure with the water stopping function comprises sheet piles which are arranged along a positioning line for supporting of the foundation pit at intervals. Grooves are formed in the two side faces of each sheet pile respectively. A concrete splicing plate used for soil blocking and water stopping is arranged between the grooves of every two adjacent sheet piles. The two ends of each concrete splicing plate are embedded into the corresponding grooves. Rubber waterstops used for water prevention are arranged at the joints of the two ends of each concrete splicing plate and the corresponding grooves. According to the sheet pile supporting structure with the water stopping function and the construction method of the sheet pile supporting structure, assembly type construction is adopted, convenience and rapidness are achieved, the concrete splicing plates have the soil blocking and water stopping functions, and the rubber waterstops have the water preventing and sealing functions; the distance between the sheet piles can be properly increased, so that the pile insertion soil squeezing effect is relieved, the integrity of the supporting structure is guaranteed, the rigidity of the supporting structure is effectively improved, and finally the safety and stability of a foundation pit project are achieved; the sheet pile supporting structure is particularly suitable for relatively regular medium and small foundation pit projects.
