However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0029] Water-based asphalt coatings are water-emulsion or solvent-based waterproof coatings made from asphalt as a base material, with the addition of emulsifiers, water, rubber, stabilizers, plasticizers, tackifiers, and other components, processed through specific techniques. Water-based asphalt coatings are widely used in various waterproof applications, such as roofs of industrial and civil buildings, concrete basements, and bathrooms; they are also suitable for corrosion and seepage prevention of underwater steel structures and cement components; and for the protection of underground pipelines and the lower water tanks of gas storage tanks.

[0030] Water-based asphalt coatings require multiple tests during production and use to ensure their quality and performance meet standards. Preparing all test specimens for water-based asphalt coatings using existing tools is cumbersome and difficult. Furthermore, improper cutting can easily result in rough edges on the specimens, leading to poor sample uniformity and affecting test results.

[0031] To address the aforementioned technical problems, this application provides an apparatus for preparing water-based asphalt specimens, which can simultaneously produce multiple test specimens of different shapes, improving cutting efficiency, saving the tediousness and difficulty of cutting, simplifying the testing process, and ensuring high specimen consistency.

[0032] The following is in conjunction with the accompanying drawings in the instruction manual. Figures 1-9 Explain in detail the structure of the apparatus for preparing water-based asphalt specimens.

[0033] This application provides an apparatus for preparing water-based asphalt specimens, comprising: a support component 1, including an easy-release template 11 and a buffer plate 12, with one side of the buffer plate 12 and one side of the easy-release template 11 joined together; a water-based asphalt supply component 2, including a power component 21 and a water-based asphalt supply element 22, the water-based asphalt supply element 22 being located above the easy-release template 11, the power component 21 driving the water-based asphalt supply element 22 to move along the length direction of the easy-release template 11, the water-based asphalt supply element 22 spraying water-based asphalt of a preset thickness onto the easy-release template 11, and the asphalt film being laid on the buffer plate 12; and a specimen forming component 3, including a pressure application component 31, an adsorption component 32 and multiple molds 33, the pressure application component 31 being connected to the adsorption component 32, the adsorption component 32 being located above the buffer plate 12, the adsorption component 32 attracting multiple molds 33, and the pressure application component 31 being able to move along the height direction of the support component 1.

[0034] Specifically, the apparatus for preparing water-based asphalt specimens includes: a support component 1, a water-based asphalt supply component 2, and a specimen forming component 3. The support component 1 includes an easy-release template 11 and a buffer plate 12. The easy-release template 11 and the buffer plate 12 are at the same height, and one side of the buffer plate 12 is seamlessly joined to one side of the easy-release template 11, thus forming the support component 1. The water-based asphalt supply component 2 includes a power component 21 and a water-based asphalt supply element 22. The water-based asphalt supply element 22 is located above the easy-release template 11. The power component 21 drives the water-based asphalt supply element 22 to move along the length of the easy-release template 11. The water-based asphalt supply element 22 sprays water-based asphalt of a predetermined thickness onto the easy-release template 11. After the water-based asphalt of the predetermined thickness dries and forms a film, it detaches from the easy-release template 11, and the film-formed asphalt is laid on the buffer plate 12. The specimen forming component 3 includes a pressure applying component 31, an adsorption component 32, and multiple molds 33. The pressure applying component 31 is connected to the adsorption component 32, which is located above the buffer pad 12. The adsorption component 32 attracts multiple molds 33. The pressure applying component 31 can move up and down in the height direction of the support component 1. The pressure applying component 31 drives the adsorption component 32 to move up and down in the height direction of the support component 1, thereby driving the molds 33 to move towards the buffer pad 12. The pressure applying component 31 applies pressure to the adsorption component 32, and the adsorption component 32 applies pressure to the multiple molds 33. The multiple molds 33 press the film-like asphalt laid on the buffer pad 12 into multiple specimens, which can simultaneously produce specimens of various shapes, improve cutting efficiency, save the tediousness and difficulty of cutting, simplify the test process, and achieve high specimen consistency.

[0035] In some optional embodiments, the waterborne asphalt supply component 2 further includes a waste material recovery component 23, which is disposed on one side of the easy-release template 11 along its own length.

[0036] Specifically, the water-based asphalt supply element 22 includes a receiving component 221 and an on / off switch 222. The receiving component 221 carries water-based asphalt and is located on the power component 21. The on / off switch 222 is located at the end of the receiving component 221 facing the easy-release template 11. The power component 21 drives the receiving component 221 to move along the length of the easy-release template 11. The on / off switch 222 controls whether the water-based asphalt inside the receiving component 221 flows out. Before the water-based asphalt supply element 2 sprays towards the easy-release template 11, the residue recovery component 23 and the water-based asphalt supply element 2 are located on opposite sides of the easy-release template 11 along its own length. As the water-based asphalt supply element 2 moves towards the residue recovery component 23, it delivers water-based asphalt to the easy-release template 11, thereby spreading a preset thickness of water-based asphalt evenly across the easy-release template 11. Excess water-based asphalt flows to the residue recovery component 23.

[0037] Furthermore, the waste material recycling component 23 is a housing with a waste material recycling trough, and the open end of the waste material recycling component 23 faces the easy-to-remove template 11.

[0038] In some optional embodiments, a water-based asphalt thickness control component 4 is also included. The water-based asphalt thickness control component 4 includes a height adjustment component 41 and a scraper 42. The height adjustment component 41 is disposed on the water-based asphalt supply element 22, and the scraper 42 is disposed on the height adjustment component 41.

[0039] Specifically, the water-based asphalt supply element 22 includes a receiving component 221 and an on / off switch 222. The receiving component 221 carries water-based asphalt and is located on the power component 21. The power component 21 drives the receiving component 221 to move along the length of the easy-release template 11. The on / off switch 222 is located at the end of the receiving component 221 facing the easy-release template 11. The on / off switch 222 controls whether the water-based asphalt inside the receiving component 221 flows out. A height adjustment component 41 is located on the receiving component 221 and extends along the height of the support component 1. The height adjustment component 41 drives the scraper 42 to move along the height of the support component 1, thereby controlling the distance between the scraper 42 and the easy-release template 11. By adjusting the distance between the scraper 42 and the easy-release template 11, the thickness of the water-based asphalt is controlled. As the receiving component 221 moves toward the waste material recycling component 23, it sprays water-based asphalt onto the easy-release template 11. The scraper 42 then spreads the water-based asphalt sprayed onto the easy-release template 11 to form asphalt of a preset thickness.

[0040] In some alternative embodiments, the height adjustment component 41 includes a first lead screw 411 and a first lead screw nut 412, the first lead screw nut 412 being disposed on the water-based asphalt supply element 22, the first lead screw 411 being connected to the first lead screw nut 412, and a scraper 42 being disposed on the first lead screw 411.

[0041] Specifically, a first lead screw nut 412 is disposed on the receiving component 221, and a first lead screw 411 is threadedly connected to the first lead screw nut 412. A scraper 42 is disposed at the end of the first lead screw 411. In use, the first lead screw 411 is rotated to adjust the distance between the end of the first lead screw 411 and the easy-release template 11. The scraper 42 is then installed at the end of the first lead screw 411, thereby determining the distance between the scraper 42 and the easy-release template 11. By adjusting the distance between the scraper 42 and the easy-release template 11, the thickness of the water-based asphalt is controlled. As the receiving component 221 moves toward the residual material recycling component 23, it sprays water-based asphalt onto the easy-release template 11. The scraper 42 then spreads the sprayed water-based asphalt onto the easy-release template 11, thereby forming asphalt of a preset thickness.

[0042] In some alternative embodiments, the water-based asphalt supply element 22 includes a receiving component 221 and an on / off switch 222. The receiving component 221 is disposed on the power component 21, and the on / off switch 222 is disposed on the end of the receiving component 221 facing the detachable template 11.

[0043] Specifically, the receiving component 221 carries water-based asphalt inside, and the on / off switch 222 is a switch that controls whether the water-based asphalt inside the receiving component 221 flows out. The on / off switch 222 is set at the end of the receiving component 221 facing the easy-to-detach template 11. When the on / off switch 222 is turned on, the water-based asphalt inside the receiving component 221 is sprayed toward the easy-to-detach template 11.

[0044] In some optional embodiments, the apparatus for preparing waterborne asphalt specimens further includes a sliding support component 5, which extends along the length of the detachable template 11.

The power component 21 is fixedly connected to one end of the water-based asphalt supply element 22, and the other end of the water-based asphalt supply element 22 is slidably connected to the sliding support component 5. The sliding support component 5 is used to support the other end of the water-based asphalt supply element 22, so that the water-based asphalt supply element 22 can move smoothly along the length of the easy-release template 11.

[0046] In some alternative embodiments, the sliding support component 5 includes a guide rail 51 and a support ring 52, the support ring 52 being slidably connected to the guide rail 51 and connected to the water-based asphalt supply element 22.

[0047] Specifically, the guide rail 51 extends along the length of the easy-release template 11, and the power component 21 extends along the length of the easy-release template 11. The guide rail 51 and the power component 21 are respectively located on opposite sides of the width of the easy-release template 11. The power component 21 drives one end of the water-based asphalt supply element 22 to move along the length of the easy-release template 11, and the other end of the water-based asphalt supply element 22 is fixed to the support ring 52. The support ring 52 can move along the length of the guide rail 51, thereby enabling the water-based asphalt supply element 22 to move smoothly along the length of the easy-release template 11.

[0048] Furthermore, the guide rail 51, support ring 52, first base 53 and second base 54 are provided. The support ring 52 is slidably connected to the guide rail 51. The length direction of the guide rail 51 is consistent with the length direction of the easy-to-detach template 11.

[0050] Specifically, the length direction of the slide rail is consistent with the length direction of the easy-release template 11. The slider drives the water-based asphalt supply element 22 to move along the slide rail, thereby driving the water-based asphalt supply element 22 to move in the length direction of the easy-release template 11.

[0051] Optionally, the driving element 213 is a motor, and the transmission components include a second lead screw 214, a second lead screw nut 215, a bearing 217, and a fixing part 218.
