Description

technical field [0001] The invention relates to a composite material, in particular to an airgel-containing composite material. In addition, the invention also designs a composite fabric made of the aerogel-containing composite material and a preparation method for the composite fabric. Background technique [0002] Airgel is a lightweight solid material with nanoscale pores accumulated by nanoscale particles. It has extremely high porosity, specific surface area, extremely low density and solid content, and is widely used in national defense and aerospace industries. and other fields. Existing hot-melt adhesive powder is widely used on clothing adhesive interlinings to change the hand feel of the original fabric, but it does not have waterproof and temperature-locking effects, and its air permeability is relatively poor. [0003] In view of the above-mentioned defects, the designer is actively researching and innovating, in order to create a composite material containing a...
