Problems solved by technology

If a large-area fully-enclosed material is used to make aerogel-containing flat film capsules as clothing interlayers, although the powder drop phenomenon can be overcome, it will cause the clothing products to have no vapor permeability, stuffy, sweaty, and poor use effect; and Also unable to overcome serious safety hazards such as long-term use or powder leakage after accidental puncture
[0010] All of the above existing airgel clothing technical solutions are trying to use the excellent thermal insulation properties of airgel to make extremely thin textile materials or interlayers. This is certainly a direction worth striving for; but it has overlooked an important one. Problem: There will always be more or less air layers between the human skin and these extremely thin textile materials or interlayers; especially there are a large number of concave-convex curved structures such as human physiological curvature, trunk cross-section depression, joint surface, etc. These concave-convex curved structures and the space formed by the natural sagging of extremely thin fabrics or interlayers make it not close to the human body, resulting in a large number of free air layers
These free air laye

Embodiment 1

[0074] Weigh 3 kilograms of airgel large-particle monomers with a size of 0.6-1 mm and blow them into a sealed stacking machine, spray polyvinyl acetate fine droplets on the tumbling airgel large-particle monomers to prepare a wrapping layer, and control the wrapping The thickness of the layer is 3-8 μm, after these wrapping layers are dried or solidified, the airgel particles with the wrapping layer that will be made are poured in the cotton scooping machine, make the fiber that the cotton scooping machine outputs and described airgel powder Large particle monomers are mixed evenly. Select 3-5 square meters of cotton or polyester cloth with a gap between the fibers smaller than the above-mentioned airgel large particle monomer, and sew it into a quilt cover. During the sewing process, select an appropriate needle size or thread thickness, and control the needle size as the number System number 6 (that is, metric system number 55, imperial system number 022, and its needle bod...

Embodiment 2

[0076] Water-based adhesive droplets, that is, water-based polyurethane emulsion droplets, are dropped on the hydrophilically modified airgel small particle powder, and such droplets can be generated in large quantities at one time through a drip plate and / or a sprayer. The water-based binder droplets will bind together the small particles of water-based airgel powder they come into contact with. By controlling the size of the droplet (that is, the total amount of the binder in the unit droplet), the size of the aggregate of small airgel particles that can be bonded can be preliminarily controlled. After the aggregates of these small airgel particles are solidified or dried, they are blown violently or blown to a state of violent boiling to collide with each other for many times to peel off the small airgel particles that are not fast enough, and then blow them by wind. And / or the vibrating sieve sieves the airgel small particle aggregate of specified size, the part on the sie...

Embodiment 3

[0082] Weigh the airgel produced by other airgel material suppliers (such as Shenzhen Zhongning Technology Co., Ltd., Suzhou Tongxuan New Material Co., Ltd., Guangdong Allison High-tech Co., Ltd. and other domestic and foreign airgel material manufacturers) Slurry, add curing agent, mix evenly, dry and solidify into blocks. Then use a pulverizer or a mixer to pulverize the dried and solidified block. After being pulverized, it is firstly blown violently or blown to a state of violent boiling to collide with each other extremely many times to peel off the small particles of airgel that are not fast enough, and then sieve the airgel with a specified size through a pneumatic and / or vibrating sieve. Gel small particle aggregates, the part on the sieve is used to make the airgel filling part in the present invention, and the part under the sieve can be returned to the previous slurry mixing process and continue to participate in the airgel mixing together with the newly added slurr...

Abstract

The invention discloses an aerogel filled structure for bedding and clothing. The aerogel filled structure comprises a breathable fabric and/or breathable film and aerogel large particle monomers and/or aerogel small particle aggregates; the aerogel large particle monomers comprise aerogel large particles and coating layers coating the aerogel large particles; the breathable fabric and/or breathable film completely coats a plurality of aerogel large particle monomers and/or the aerogel small particle aggregates; the sizes of the aerogel large particle monomers and/or the aerogel small particleaggregates are greater than that of breathable gaps and needle holes of the breathable fabric and/or breathable film. The aerogel filled material disclosed by the invention is prepared into clothingand bedding to realize the advantages that excellent heat insulation performance and high body fitness are achieved; a free air layer inside clothing is reduced or even eliminated and further the insulation performance is improved; the phenomenon that powder falls from aerogel is avoided and health hazard to a user is avoided; in addition, the phenomenon that the heat insulation performance gets poorer due to the reduction of the aerogel caused by powder falling is prevented; besides, the clothing and bedding have the characteristics of breathability, no stuffiness and high comfortableness.

Description

technical field [0001] The invention belongs to the field of filling materials for clothing and bedding, and relates to a powder-free and vapor-permeable airgel filling structure and the prepared clothing and bedding, in particular to ultra-thin clothing, quilts, sleeping bags, hats and gloves containing airgel . Background technique [0002] Airgel is currently known as the solid with the best thermal insulation performance and the lowest density. It can lock a large amount of still air in a small space, has extremely low thermal conductivity, and is extremely light in weight. It has excellent performance as a thermal insulation material. However, airgel is a brittle material, and it cannot be directly applied to clothing and bedding as a whole or a whole piece of products that need to be repeatedly bent during use and / or storage; therefore, the airgel must first be made into particles or powders and then Make it attached or wrapped into other substrates for use.
