Abstract

The invention relates to aquosity polyurethane, organic silicon, and organic fluorine copolymerization water proof gasper drenching antibiotic coating adhesive preparing method. It includes the following steps: using diisocyanate to react with diatomic alcohol compound, alkyl silicol, hydroxyl group fluoro-silicon oil, dioxy methyl propionic acid to produce performed polymer with -NCO end group, enlarging chain by 1, 4 butylene glycol; using amine to adjust pH value to neutrality; adding de-ionized water contains anti-bacterial agent to stir at high speed; adding water to adjust viscosity. It can be coated at the fabric surface to realize water proof gasper drenching, and kill mold.

Description

technical field [0001] The invention relates to a polyurethane waterproof, breathable, and moisture-permeable coating glue, in particular to a preparation method of a water-based polyurethane, organic silicon, and organic fluorine copolymerized waterproof, breathable, and moisture-permeable antibacterial coating glue. It belongs to the field of organic chemical technology. Background technique [0002] Polyurethane waterproof, breathable and moisture-permeable coating glue is widely used in textile and leather fields, and can endow the coating with special effects of waterproof and moisture permeability. At present, the coating glue of polyurethane is still mainly oily polyurethane, which releases a large amount of harmful organic solvents during production and coating, which is extremely unfriendly to the environment. The new waterborne polyurethane material has great market potential due to the use of non-toxic water as the dispersion medium. But water-based coating adhe...
