Problems solved by technology

However, this prior art needs a composite spinning process in which light-absorbing particles are mixed into fiber filaments when fiber spinning is performed, so it requires relatively high preparation costs, and because the surface area of ​​light-absorbing particles is not large,

Embodiment 2

[0056] Such as figure 2 As shown in the lower part of , the carbon nanotube coating liquid prepared by the method of Example 1 above was applied to the No. 1 area of ​​the 10cm×10cm fiber sample, and the thermal storage fabric was prepared according to the same method as Example 1.

Embodiment 3

[0061] In order to prepare carbon nanotubes, a mixed solution of nitric acid and sulfuric acid (3:1) is used to oxidize the surface of single-walled carbon nanotubes prepared by the arc-discharge method to prepare single-walled carbon nanotubes with improved dispersion properties. Tube. 5% by weight of the acid-treated single-walled carbon nanotubes, 5% by weight of a dispersant (trade name: SDS), 0.2% by weight of an antifoaming agent (trade name: Surfynol 104H), and 43.3% by weight of distilled water were mixed, and mixed at 140W (70%) power to apply ultrasound for 1 hour to disperse the carbon nanotubes. 50% by weight of a water-dispersible polyurethane binder (trade name: Sancure 12954) and 1% by weight of a tackifier (trade name: Carbopol EP-1) were mixed in the above dispersion liquid , and stirred in a mixer for 30 minutes to prepare a coating solution. According to the method of Example 1, the coating solution was applied to a 10 cm x 10 cm fiber sample to prepare a ...

Abstract

According to the present invention, a carbon nanotube heat storage textile is prepared by a method in which one or both surfaces of a textile are coated with a coating solution containing a carbon nanotube. The coating solution comprises 0.1-15 wt% of a carbon nanotube (CNT), 0.01-5 wt% of a dispersant, 9.89-70 wt% of a resin binder, and 10-90 wt% of a solvent. 0.01-5 parts by weight of an additive can be further added on the basis of 100 parts by weight of the coating solution. Preferably, the carbon nanotube is surface-modified to improve the adhesion and dispersion with the resin binder. The carbon nanotube can be a single wall nanotube (SWNT), and can preferably be a multi-wall carbon nanotube such as a double wall nanotube (DWNT), a thin multi-wall nanotube (thin MWNT), a multi-wall nanotube (MWNT), and the like. The coated coating solution is cured while transferring the coated heat storage textile with a constant velocity at a room temperature or in a heated chamber.

Description

technical field [0001] The invention relates to a heat storage and heat preservation fabric. Specifically, the present invention relates to a heat storage and heat preservation fabric and a preparation method thereof. The above heat storage and heat preservation fabric is coated with a carbon nanotube composition liquid on the surface of the fabric, and because it contains carbon nanotubes, it can bring heat storage and heat preservation effects. Background technique [0002] If the fiber fabric absorbs heat and stores it inside, it can enjoy various advantages brought by the thermal insulation effect. In particular, if fabrics for clothing or household fabrics such as curtains and sofas have heat storage and heat preservation effects, it is possible to save various costs caused by heating and enjoy a comfortable life. For this purpose, continuous efforts are being made to develop fibers or fabrics having heat storage or heat retention functions. [0003] Korean Patent Pub...
