The aqueous refrigeration coatings of examples 1-8 and comparative examples 1-8 were sprayed onto the surface of ABS substrates using the same spray coating process to form a coating layer having a thickness of 100 μm, and the performance of the coating layer was tested and the results are shown in tables 1 and 2.
TABLE 1
TABLE 2
As can be seen from tables 1 and 2, the pigment base designed by the invention is relatively low, and the coating has excellent flexibility, hand perspiration resistance, cosmetic resistance and other properties. The test data shows that the rutile titanium dioxide has strong solar reflectance, but the hemispherical emissivity is lower when the rutile titanium dioxide is singly used, and the addition of silicon oxide, silicon carbide, boron nitride and zinc oxide powder in the coating is beneficial to improving the hemispherical emissivity of the coating. In addition, the addition of talcum powder, mica, barium sulfate, calcium carbonate and other powder can also improve the partial reflectivity and emissivity, and the addition of surface hydrophobic auxiliary agent can help to improve the surface hydrophobic property of the coating.
The test standards for solar reflectance and near infrared reflectance were: the test criteria for JG/T235-2014, hemispherical emissivity are: T/ZZB2304-2021; the adhesion test criteria were: GB/T9286-1998; the water contact angle test criteria were: GB/T30693-2014; the bending test method comprises the steps of using a bending clamp to bend 120 degrees, and bending for 30 times; the cold and hot impact testing method comprises the following steps: placing the sample in a temperature impact test box, firstly, keeping the sample in a low-temperature environment of-40+/-2 ℃ for 0.5 hour, switching the temperature to a high-temperature environment of 80+/-2 ℃ within 5 minutes, and keeping the sample for 0.5 hour, and performing 48 cycles; the hand perspiration resistance test method comprises the following steps: the dust-free cloth soaked with sweat (PH=6.5) is stuck on the surface of the product and sealed by a plastic bag, and after the product is placed for 48 hours under the conditions of temperature (55+/-2 ℃) and humidity 95+/-5%RH, the sweat on the surface of the product is wiped clean and then the adhesive force is tested; the method for testing the absolute ethyl alcohol resistance comprises the following steps: the adhesion was tested after 1h immersion in absolute ethanol (99.8% strength); the hand cream resistance test method comprises the following steps: vaseline hand cream is coated on the whole appearance surface of the product, then the sample plate is placed in an incubator (55+/-2 ℃ and humidity 95+/-5% RH), and the adhesive force is taken out after 24 hours.
