Abstract

The invention provides an antimicrobial thermal-insulation coating for fabrics and a preparation method thereof. The fabric coating has favorable thermal insulation property and is harmless to human bodies. The preparation method has the advantages of simple technique and low production cost, and is suitable for industrial production. The fabric with the composite coating is applicable to the fields of outdoor supplies, clothing, construction, military affairs and the like, and is widely applied to the occasions in need of heat preservation and thermal insulation. The coating comprises the following components in percentage by weight: 20-30% of ethanol, 5-10% of dioctyl phthalate, 0.6-0.9% of polyvinyl formal, 15-20% of zinc sulfide/magniferous aluminum oxide composite material, 5-12% of polyethyleneglycol and the balance of polyurethane.
