Abstract

The invention provides a thermal insulation composite coating and a preparation method as well as application thereof. The composite coating is used for coating fabrics, has good heat insulation property and is harmless to a human body. The preparation method is simple in technology, low in production cost and suitable for industrial production. The thermal insulation composite coating is applied to the fabrics and can be used for coating the multiple fabrics; and the obtained thermal insulation fabrics are suitable for the fields of outdoor goods, clothing, buildings, military and the like and are applied to occasions needing heat preservation and insulation in large quantities. The composite coating comprises the following components in percentage by weight: 20-30% of alcohol, 5-10% of dioctyl phthalate, 0.6-0.9% of phosphate ester, 15-20% of titaniferous silicate complex, 5-12% of polyacrylic resin and the rest of polyurethane.

Description

Technical field: [0001] The invention belongs to the technical field of coatings, relates to a heat-insulating composite coating and its preparation method and application, and belongs to the field of materials. Background technique: [0002] Patent No. CN200910056507.8 relates to a finishing method for solar heat insulation of dark-colored pure cotton and its blended fabrics in summer. The preparation process includes adding tetraethyl orthosilicate and ethanol, stirring evenly; adding ethanol, triethanolamine and water in sequence, and Stir evenly under temperature conditions; add the above mixed solution dropwise to the previous mixed solution. The specific method includes ①adding 1-30g tetraethyl orthosilicate and ethanol with a weight percentage of 50-95%, stirring evenly with a magnetic stirrer; ②adding 80-100ml ethanol, 2-5ml water and 6ml triethanolamine in turn. Under the temperature condition of ℃, stir evenly with a magnetic stirrer, in which triethanolamine is...
