Description

Technical Field

[0002] As a material with good thermal insulation, aerogel has broad application prospects in aerospace, petrochemical, electric power metallurgy, shipbuilding and vehicle fields. In order to improve the thermal insulation effect, aerogel coatings are usually prepared, and the thermal insulation properties of aerogel are used to improve the overall thermal insulation capacity of the coating. Pigments can be added to the aerogel coating according to different usage scenarios to produce aerogel coatings of different colors.

[0003] In the prior art, when processing aerogel coatings, pigments of different colors are added and mixed according to the needs of use. After sufficient stirring, the device needs to be fully opened to fully expose the internal aerogel coating. The internal aerogel coating is then taken out to detect whether there is a large color difference to ensure that the product is qualified before filling.

[0004] When processing aerogel coatings of different colors in the prior art, it is necessary to first mix the aerogel coating and the pigment. After the stirring is completed, a small portion of the aerogel coating needs to be taken for color difference detection. In order to improve the accuracy of the test results and simultaneously detect the uniformity of the mixing of the pigment and the aerogel coating, it is necessary to sample and test both the upper aerogel coating and the lower aerogel coating. When sampling and testing aerogel coating in the prior art, the stirring barrel is generally fully opened, and then samples are taken from the liquid surface of the aerogel coating for testing. There may be color differences between the upper and lower aerogel coatings. At the same time, when testing the deep aerogel coating, the sampling tube needs to be extended from the liquid surface into the interior for sampling. During the process of extending the sampling tube from the liquid surface into the interior of the aerogel coating, the sampling tube is always in contact with the aerogel coating, which may lead to inaccurate sampling of the deep aerogel coating, thereby causing inaccurate test results.

[0040] Step 4: Take out part of the mixed paint in the mixing barrel 1 and apply it on the surface of the color test paper 24, then use the colorimeter 221 to detect the color of the mixed paint, adjust the amount of pigment added according to the detection result, until the color of the mixed paint is qualified, and use the colorimeter to detect whether there is a color difference between the mixed paint after stirring, and if the detection is qualified, the next processing step can be carried out. When a color difference is detected, the corresponding pigment can be added according to the detection result and the stirring is continued until the color detection is qualified;

[0041] Step 5: Fill the qualified mixed coating in the mixing barrel 1 to obtain a finished aerogel coating.

[0042] In step 4, when the aerogel coating in the mixing barrel 1 is tested, the mixed coating in different parts of the mixing barrel 1 is taken out for testing multiple times.

[0043] Embodiment 2

[0044] like Figure 1-Figure 4 As shown, an aerogel coating preparation device, which is suitable for the above-mentioned aerogel coating preparation method, comprises a stirring barrel 1, wherein a plurality of stirring blades are arranged in the stirring barrel 1 for stirring the aerogel coating, a rectangular shell 2 is fixedly connected to one side of the stirring barrel 1, and a detection device is arranged inside the rectangular shell 2, characterized in that: the detection device comprises a plurality of material taking components arranged on one side of the stirring barrel 1, the material taking component comprises a first cylinder 21 arranged on one side of the stirring barrel 1, the first cylinder 21 is connected to the inside of the stirring barrel 1, the first cylinder 21 is used for temporarily storing the aerogel coating, a cylindrical block 212 is slidably arranged in the middle of the first cylinder 21, a rectangular hole 215 is opened on one side of the first cylinder 21, a color test paper 24 is arranged on one side of the first cylinder 21, a detection component is arranged on one side of the inner part of the rectangular shell 2, and the detection component comprises a colorimeter 221 slidably arranged on one side of the rectangular shell 2.

[0051] Specifically, a rolled color test paper 24 is sleeved on the outside of the second cylindrical rod 23, and the end of the color test paper 24 is pulled out and fixed on the outside of the third cylindrical rod 231. When the aerogel coatings at different parts of the mixing barrel 1 are simultaneously sucked into the first cylinder 21, the third cylindrical rod 231 is driven to rotate, driving the color test paper 24 to slide along the rectangular hole 215, so that the aerogel coating inside the first cylinder 21 is applied to the surface of the color test paper 24. After a certain amount of aerogel coating is applied, the cylindrical block 212 is driven to slide toward the side close to the mixing barrel 1, so that the first cylinder 21 can be The aerogel coating in the cylinder 21 is pushed into the stirring barrel 1, and then the third cylindrical rod 231 is driven to rotate, and one side of the test paper 24 coated with the aerogel coating is rotated to the side of the colorimeter 221, so as to be parallel to the colorimeter 221. Then, the aerogel coating coated on the surface of each test paper 24 can be tested for color difference. When the test is completed, the third cylindrical rod 231 can be driven to rotate to rotate the test paper 24 coated with the aerogel coating to the outside of the third cylindrical rod 231, and the new test paper 24 can be pulled out to carry out a new round of testing.

By providing a rotating wheel 27 on one side of the test paper 24 to be close to the test paper 24, and the rotating wheel 27 is located on both sides of the rectangular hole 215, the test paper 24 can be pressed against both sides of the edge of the rectangular hole 215 to prevent the aerogel coating from flowing out from between the rectangular hole 215 and the test paper 24. When the test paper 24 is pulled, the rotating wheel 27 is driven to rotate to prevent the test paper 24 from being rubbed.

[0054] like Figure 3-Figure 4 As shown, a slide rail 22 is fixedly connected to one side of the interior of the rectangular shell 2, and the colorimeter 221 can slide on one side of the slide rail 22.
