Problems solved by technology

[0014] Although the above patents have improved the design of various technical solutions for flame retardant fabrics, they do not involve bio-based materials, nor do they involve the content of environmentally friendly materials. Moreover, the technical solutions using polyester flame retardant black silk materials cannot achieve higher In other coating schemes, there is always a chemical layer on the back of the fabric. When consumers buy fabrics, they directly touch the chemical layer on the back, and the experience is not good.

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.

Description

technical field [0001] The invention relates to the field of flame retardant materials, in particular to bio-based flame retardant materials and their preparation methods and applications. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for product performance continue to increase. At present, more and more attention has been paid to the flame retardancy, environmental protection and environmental friendliness of materials, and relevant standards are constantly being formulated and improved. [0003] In terms of flame retardancy, a series of standards have been issued at home and abroad. For example, GB20286-2006 "Requirements and Marking of Flame Retardant Products and Components in Public Places", GB8624-2012 "Classification of Combustion Behavior of Building Materials and Products", BS5867-2:2008 "Specification for Curtains and Curtain Fabrics - Part Two: Flammability Requirements (2008), DIN 4102-1 "Fire...
