Embodiment 1

[0028] A ZSE 40 type twin-screw extruder (Leistritz company) with an aspect ratio of 52:1 was first used to prepare PCM polymer particles from the following raw materials:

[0029] -80wt% PCM material (Sasol GmbH's ether 12, long chain dialkyl ether, melting point is 32°C)

[0030] -10 wt% styrene block copolymer SEEPS (polystyrene-b-poly(ethylene-ethylene / propylene)-b-polystyrene; Kuraray Co.Ltd.'s 4055)

[0031] -5wt% hydroxy-terminated styrene block copolymer (Kuraray Co.Ltd.'s HG 252) - 5 wt% crystalline ethylene-butene copolymer (Typ 6201B from JSR Dynaron).

[0032] The extrusion die was connected to the cutting head of an underwater pelletizer (Gala underwater pelletizer, Gala Inc.) through an adapter plate. Particles with a diameter of 4-5 mm are obtained.

[0033] The obtained particles had a heat storage capacity of 215 J / g at the PCM phase transition temperature with a switching temperature of 32°C.

[0034] The PCM polymer particles were dried in a circula...

Embodiment 2

[0041] Similar to that described in Example 1, PCM polymer particles of the following composition were prepared in a ZSE 40 Leistritz twin-screw extruder with downstream underwater pelletizer:

[0042] -80wt% PCM material (Sasol GmbH's ether 12, long chain dialkyl ether)

[0043] - 10 wt% styrene block copolymer SEBS (polystyrene-b-poly(ethylene / butylene)-b-polystyrene; Septon 8004 by Kuraray Co. Ltd.)

[0044] -5wt% hydroxy-terminated styrene block copolymer (Septon HG 252 from Kuraray Co. Ltd.)

[0045] - 5 wt% crystalline ethylene-butene copolymer (Typ 6201B of JSR Dynaron),

[0046] After drying it is applied to a coarse mesh polyamide fabric in a single-screw extruder using a special casting tool.

[0047]The polymer fabrics with PCM polymer castings (rectangular or cylindrical) were then sprayed on both sides with a 5% by mass polyamide solution (composed of Ultramid 1C) and the excess solvent was evaporated at room temperature.

[0048] The polyamide coating has a ...

Embodiment 3

[0050] PCM polymer granules were also prepared in a ZSE 40 Leistritz twin-screw extruder and downstream underwater pelletizer similarly to that described in Example 1, which were dried in a single-screw extruder using a special casting tool Apply to coarse mesh polyamide fabric.

[0051] But here the composition of matter of the PCM polymer is changed:

[0052] -70wt% PCM material (Sasol GmbH's ether 16, long chain dialkyl ether)

[0053] -8wt% styrene block copolymer SEEPS (Septon4055 of Kuraray Co.Ltd)

[0054] -4wt% hydroxy-terminated styrene block copolymer (SeptonHG 252 from Kuraray Co.Ltd.)

[0055] -3wt% crystalline ethylene-butene copolymer (JSR Dynaron's Typ 6201B)

[0056] -15wt% zinc oxide powder

[0057] Prepared in a ZSE 40 Leistritz twin-screw extruder with a downstream underwater pelletizer, it is dried and coated onto a coarse mesh polyamide fabric in a single-screw extruder using a specific casting tool.

[0058] Zinc oxide not only increases thermal co...

Abstract

The present invention relates to flexible PCM fabrics with high potential thermal energy storage density for thermal management. The flexible PCM fabric is composed of a flexible support structure and a phase change material body arranged on the support structure in a special geometric shape. The phase change material body itself includes a geometrically defined structure of polymer bound phase change material. Flexible PCM fabrics are characterized by a high potential heat storage capacity and optimized thermal conductivity, which maintain shape stability even during temperature changes and after phase changes, and are easy to roll, fold, wrap or cut, and can be single-layer or Multi-layer transportation, storage, processing or use.

Description

technical field [0001] The present invention relates to flexible PCM fabrics with high potential thermal energy storage density for thermal management. The flexible PCM fabric is composed of a flexible carrier structure and a phase change material body arranged on the carrier structure in a specific geometric shape. The phase change material body itself comprises a geometrically defined structure of polymer bound phase change material. Flexible PCM fabrics are characterized by a high potential heat storage capacity combined with optimized thermal conductivity, are shape-stable even during temperature changes and after phase transitions, and can be rolled, folded, wound or cut without problems, either in single layers or Multi-layer transportation, storage, processing or use. Background technique [0002] From US20020164474 flexible heat regulating materials are known, which can be used in socks, shoe linings or other garments. To prevent loss of phase change materials (PC...
