Description

technical field [0001] The present application relates to the technical field of radiation refrigeration, in particular to an intelligent refrigeration artificial leather and a preparation method thereof. Background technique [0002] Artificial leather is a cloth-based synthetic material made of fabric as the base, coated with synthetic resin and various plastic additives. Natural leather is expensive, difficult to mass produce, and has uneven color quality. The base of artificial leather is prepared by using non-woven fabric or woven fabric, which not only overcomes the shortcomings of natural leather, but also has an appearance and feel comparable to natural leather, and is widely used in many fields such as the automobile industry. However, the heat dissipation of artificial leather is poor, covering the surface of the object will cause the heat to be unable to dissipate, resulting in damage to parts, aging and other problems; and the temperature of the leather itself c...
