specific Embodiment approach 1

[0025] Specific implementation mode one: the preparation method of the inner filler of the ultra-light thermal clothing in this embodiment is implemented according to the following steps:

[0026] 1. Preparation of graphene oxide: Add natural flake graphite into strong oxidizing mixed acid, stir for 10min-60min at a stirring speed of 100r / min-800r / min, then add strong oxidant permanganate in 3-10 times Potassium to prepare mixture A, then put mixture A in a water bath at 30°C to 80°C, and stir at a constant temperature for 4h to 20h at a stirring speed of 200r / min to 800r / min to obtain mixture B, and then mix mixture B Adding it into ice water, and adding hydrogen peroxide with a mass fraction of 30% to the ice water to obtain a graphite oxide suspension, washing with suction, centrifugal washing and drying, to obtain graphene oxide;

[0027] 2. Preparation of graphene oxide dispersion: Add the graphene oxide obtained in step 1 into deionized water and stir evenly to obtain a ...

specific Embodiment approach 2

[0036] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the mass ratio of the volume of the strong oxidizing mixed acid described in step 1 to the natural flake graphite is (10mL-400mL): 1g. Other parameters are the same as in the first embodiment.

specific Embodiment approach 3

[0037] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the strong oxidizing mixed acid described in step one consists of phosphoric acid with a mass fraction of 10% to 85% and sulfuric acid with a mass fraction of 10% to 98% by volume Ratio (3~10):1 composition. Other parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention provides a preparation method for filling materials in ultra-light warm clothes and application of the filling materials in the ultra-light warm clothes, and relates to a preparation method for sponge materials of filling materials in warm clothes. The problem that the heat retention property and the attractiveness of filling materials, which are prepared by using the existing method, in the warm clothes are conflicting is solved. The preparation method comprises the following steps of (1), preparing oxidized graphene by using natural crystalline flake graphite; (2) preparing oxidized graphene dispersion liquid; (3) preparing dispersion liquid by using a carbon nano tube and surface active agents; (4) preparing oxidized graphene and carbon nano tube solution; (5) performing freeze drying on the oxidized graphene and carbon nano tube solution; (6) performing reduction on an oxidized graphene and carbon nano tube sponge; and (7) drying the sponge so that the preparation on the ultra-light sponge is finished. The application comprises that the prepared ultra-light graphene and carbon nano tube sponge is filled between an outer fabric and an interlining fabric of the warm clothes. The sponge has ultra-low density and ultra-low heat conductivity coefficient; and the thickness of the warm clothes is reduced, so that the warm clothes are light and attractive.

Description

technical field [0001] The invention relates to a preparation method and application of a sponge material which can be used as an inner filler of warm clothes. Background technique [0002] Warm clothing is the most important kind of cold-proof clothing for people in the long winter. It has excellent thermal performance under severe cold conditions and is easy to wear, so it has been welcomed by consumers. When people improve the ability of thermal clothing to keep out the cold, they often make thicker fleece liners. Although the thermal insulation properties of thermal clothing are improved to a certain extent, this also directly increases the quality of thermal clothing on the other hand. At the same time, too thick thermal clothing also destroys the aesthetics of thermal clothing, which does not meet people's increasingly higher requirements for thermal clothing. Therefore solving the coexistence of warmth and aesthetics of thermal clothing has become a difficult problem...
