[0002] Temperature-sensitive coatings are commonly used in clothing and luggage, primarily through coating or spraying fabric or leather coils, as well as custom printing. However, in actual applications, they often suffer from low temperature sensitivity.

[0003] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0004] In response to the problems in the related art, the present invention proposes a thermal insulation coating for temperature-changing coatings to overcome the above-mentioned technical problems existing in the existing related art.

[0005] To this end, the specific technical solutions adopted in the present invention are as follows:

[0007] The heat-insulating coating comprises the following components and their contents in parts by weight: 20-80 parts of resin, 0-1 part of pigment, 10-40 parts of solvent cyclohexanone, 10-40 parts of ethyl acetate, 1-20 parts of reinforcing agent, 0.2-0.8 parts of antioxidant, and 0.07-0.5 parts of ultraviolet absorber.

[0008] Preferably, the reinforcing agent is a hard reinforcing agent, which is a composition of hollow glass microspheres and a toughening agent in a mass ratio of 1-1.5:2-2.5. Preferably, the reinforcing agent is a flexible reinforcing agent, which is a foaming agent.

[0009] Preferably, the resin is any one of epoxy resin, PVB resin, TPU resin and PU resin.

[0010] Preferably, the antioxidant is any one of BASF1076, BASF245, BASF168, BASF136, and BASF1010.

[0011] Preferably, the specific model of the ultraviolet absorber is any one of UV-328, UV-5411, UV-531, UV-329, and UV-312.

[0012] As a preferred method, the preparation method is:

[0013] S1 Take a beaker, add ethyl acetate, turn on the precision power-boosting electric stirrer, set the speed to 70 rpm, and add cyclohexanone dropwise;

[0014] S2 is heated using a heating jacket, the temperature is set at 60°C, and antioxidant is added;

[0015] S3 After the antioxidant is fully dissolved, add the ultraviolet absorber;

[0016] After S4 is completely dissolved, add toughening agent;

[0017] Adjust the temperature of S5 to 120℃, add resin, and adjust the speed to 140 rpm;

[0018] S6: After the resin is fully dissolved, add the hollow glass microspheres in small amounts and multiple times. After all the microspheres are added, adjust the speed to 100 rpm and the temperature to 140°C until they are fully dispersed.
