Raw materials of the fabric back lining heat insulation coating comprise deionized water, a styrene acrylic emulsion, talcum powder, light calcium carbonate, ammonia water, polyvinyl chloride, an activator, an antioxidant, a foaming agent, a coloring agent, a coagulating agent, a filler, a thickener and zinc dimethyldithiocarbamate. The surface drying time of the above product is 10-30min, and the hard drying time of the product is 50-90min; the fire resistance time is 30-60s, and the fire resistance weight loss is 2-4g; the adhesion is 98-100%, the impact strength is 60-70cm, the levelability is extremely good, and a coating film can resist saturated calcium hydrate immersion for 10-20d; the coating film does not shed or mildew after being immersed in water for 20-30d; the gloss is 96-100%, the flexibility is 1-5mm, and the service life of the coating film is long; and the sagging resistance and the storage stability of the product are good.

Description

technical field [0001] The present application relates to a paint, in particular to a fabric-backed thermal insulation paint. Background technique [0002] Most of the existing heat-insulating coating products are used on the surface of concrete or metal structures to achieve heat-insulating effect. The flexibility, compactness and adhesion of this type of heat-insulating coating are generally poor, so it is not suitable to be painted on textiles for heat insulation. insulation. But along with the wide application of outdoor textiles and sunshade curtains, people's requirements for the thermal insulation performance of textiles are also getting higher and higher. Therefore, it is very necessary to design a fabric-backed thermal insulation coating with high bonding strength, fast drying, high tensile strength, high elongation at break and long flame-resistant time and its preparation method to meet market demand. Contents of the invention [0003] Technical issues solved:...
