Description
Technical field
The present invention relates to dress materials preparation and application fields, more particularly, to a kind of high insulation garment material and its preparation
Method.
Background technique
Low temp operation needs staff to work in subzero even subzero tens degree of environment for a long time, generally
Fabric be unable to satisfy people for cold resistance.In this regard, someone selects extremely thick velveteen clothes, but its there are it is too fat to move not
Just, the disadvantage of flexibility difference；Also someone selects metal wool as heat insulating material, but its penetrability, wet guilding and flexibility are poor；
Somebody makes insulation garment using better built up membrane heat insulating material, but its airtight, not moisture-inhibiting, punching effect it is poor,
The disadvantages of skin sense is bad.
Aeroge is the product in the case where keeping gel skeleton structural integrity, after gel internal solvent is dried, and is
Amorphous state low density material with nano-porous structure.Aerosil is the material that thermal insulation property is best so far
Material.Since its intensity is low, brittleness is big, insufficient, the caducous phenomenon of particle that there are flexibilities causes the silica aerogel of the prior art
