The anti-cold feeling coatings prepared by the scheme 1, the scheme 2, the scheme 3 and the scheme 4 are respectively named as coating 1, coating 2, coating 3 and coating 4 in sequence, and the 4 coatings are respectively coated on 4 same aluminum plates by a roller and dried. And respectively roller-coating the transparent cold-feel-resistant coatings a, b, c and d provided in the embodiment 4 on the fluorocarbon coating 1, the fluorocarbon coating 2, the fluorocarbon coating 3 and the fluorocarbon coating 4, quickly drying, and then placing for 7 days at normal temperature.

From the above comparative experiments, the following conclusions were drawn:
1. comparing scheme 1, scheme 2 and scheme 3, when the content of the diatomite is increased, the heat conductivity coefficient of the whole aluminum plate is reduced, and the hand feeling is not cold when touching. When the content of diatomaceous earth reaches 10%, there arises a problem of a decrease in adhesion, and the cold feel resistant coating gives a noticeable granular feel. Therefore, scheme 2 is superior to scheme 1 and scheme 3 in use. Therefore, the content of the diatomite can be adjusted by those skilled in the art according to actual needs to achieve the best use effect.
2. Comparing scheme 2 with scheme 4, scheme 4 increases the content of the nano siloxane modified fumed silica, so that the aluminum plate 4 can achieve a better cold feeling resistant effect. However, the aluminum plate 4 had a significantly reduced gloss as compared with the aluminum plate 2. Therefore, according to actual needs, a person skilled in the art can adjust the content of the nano siloxane modified fumed silica in the cold-feeling-resistant coating to achieve the optimal use effect when the cold-feeling-resistant coating is roll-coated on the surface of the cold-feeling-resistant coating.
