Abstract

The invention discloses an environment-friendly bio-based high-shading flame-retardant composite material. The composite material comprises a fabric layer, a base fabric layer and a middle layer; environment-friendly bio-based macromolecules, various flame retardants, fillers and functional auxiliaries are adopted, a prepared bio-based shading film serves as the middle layer, and the middle layeris bonded with the fabric layer and the base fabric layer through flame-retardant PUR hot melt adhesives. According to the product high shading can be realized, high-efficiency carbon formation and flame retardance can also be achieved, and good biodegradability is also achieved; the composite product has the advantages of environmental friendliness, greenness, environmental protection, no peculiar smell, safety and health, can be widely applied to the fields of curtains, tents, curtains, shower curtains, sunshade curtains and partition curtains, and can play a role in flame retardance and shading in public places, vehicles, home places and the like.
