Abstract

The invention discloses a nano coffee carbon function film with windproof air-permeable heat-accumulating warm-keeping effects. Polyurethane resin, water, toluene, butanone, 1,6- diisocyanato-cyclohexan, N-methyl ethanolamine, nano coffee carbon particles, a dispersing agent and a waterproofing agent are weighed according to the proportion of 100:40:20:20:3:1.5:10:1:0.5. The water, the toluene and the butanone are sequentially injected into a reaction kettle to be mixed to form a first resin solution. The 1,6- diisocyanato-cyclohexan and the N-methyl ethanolamine are sequentially injected into a first main resin solution to form a second resin solution. The nano coffee carbon particles are placed into the second resin solution. The dispersing agent and the waterproofing agent are sequentially added into macromolecule inorganic substance composite size. Prepared macromolecule inorganic substance is compounded to prepare film size. The nano coffee carbon function film is provided with even and compact nanoscale micropores, film indexes can reach 8000mm of hydrostatic pressure and 22000g / m<2> / 24h of moisture permeability, and the film combines a natural honeycomb structure of coffee carbon and a far infrared function and has the heat-accumulating warm-keeping antibacterial mite-inhabiting and far infrared health-care effects.

Description

technical field [0001] The invention relates to a nano-coffee carbon functional film with wind-proof, vapor-permeable, heat-storing and warm-keeping functions, which belongs to the technical field of textile fabrics. Background technique [0002] The existing polyurethane film is composed of a single-component copolymer, and its performance only has the basic functions of waterproof, moisture permeability, and vapor permeability. requirements. Contents of the invention [0003] The purpose of the present invention is to provide a nano-coffee carbon functional film with windproof, vapor-permeable, heat-storing and warm-keeping effects. The nano-coffee carbon functional film has uniform and dense nanoscale micropores of 50-200nm, and the film index can reach 8000mmH2O hydrostatic pressure and 22000g / m 2 / 24h moisture permeability, which can fully meet people's requirements for dry and comfortable clothing. Combined with the natural honeycomb structure of coffee carbon and...
