Description
[0001] The disclosure relates to the field of artificial leathers, and more particularly, to a
temperature self-adjustment leather comprising phase change microcapsules and a
method for preparing the same.
[0002] Artificial leather is a kind of leather-like plastic products, usually based on
woven or non-woven fabrics, processed by foaming or laminating films of various
formulas such as PVC or PU, subsequently heated and plasticized, and then rolled or
embossed. Artificial leather may be made with characteristics of various colors, good
waterproof performance, high utilization rate, and low price according to requirements of
different strength, color, luster, and patterns. In addition, artificial leather is similar to
natural leather and has characteristics of softness and worn resistance.
[0003] Phase change materials (PCM phase change microcapsule additives) can absorb
and release a large amount of latent heat of phase change during the phase change
process, and can be widely used in the fields of energy storage and temperature control.
[0004] Temperature self-adjustment performance of artificial leather is an important
factor affecting comfort of leather products. Especially, in outdoor products, leather that
can effectively control the temperature can greatly improve use value and economic value
thereof.
[0005] At present, leathers in the market, especially for outdoor use and automotive use,
I do not have temperature self-adjustment performance. The foamed layer of leather is a porous carrier, which is easier to absorb and contain chemical materials than flat textile fibers, and appears as a spatial network with stronger adsorption and larger adsorption capacity. In view of this, the disclosure adds a special phase change material to artificial leather slurry, and prepares a leather fabric with self-temperature through a series of special production procedures, which fills the market vacancy.
[0006] Based on the above, temperature self-adjustment leather comprising phase
change microcapsules and a method for preparing the same are provided.

comprises:
[0013] 1) weighing the color paste, defoamer, thickener, PCM phase change
microcapsule additives and water-based polyurethane resin according to a formula for the
PU foam layer;
[0014] 2) adding the color paste, the defoamer, the thickener, the PCM phase change
microcapsule additives, and the water-based polyurethane resin into a clean bucket in
order, and uniformly stirring a resulting slurry with a vertical mixer for 30-35 minutes;
[0015] 3) pouring the slurry into an open mill and processing the slurry for 25-30 min;
[0016] 4) transporting the slurry processed in 3) to a calender, and evenly coating the
slurry onto a circulating release paper through a rotating belt roller of the calender;
[0017] 5) putting the release paper obtained in 4) into a first oven for pre-solidification;
[0018] 6) laminating the release paper with semi-solidified slurry to the base fabric
layer;
[0019] 7) putting the release paper with the base fabric layer in a second oven,
plasticizing or foaming the slurry at high temperatures, and removing the plasticized or
foamed slurry from the second oven to cool and dry; and
[0020] 8) peeling off the dried foam layer from the release paper, thereby obtaining a
temperature self-adjustment leather.
[0021] Further, in 3), the rotating speed of the drum of the open mill is 100-110 r/min,
and the temperature inside the open mill is 90-110°C.
[0022] Further, in 4), the temperature of the pressure roller of the calender is 140
160°C, and the rotating speed thereof is 110-130 m/min.
[0023] Further, in 2), the water-based polyurethane resin, the thickener, the defoamer,
