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 light-shielding and flame-retardant composite material, which comprises a fabric layer, a base fabric layer and an intermediate layer. The invention adopts environment-friendly bio-based macromolecules and various flame retardants, fillers and functional additives, and prepares the bio-based light-shielding film as the intermediate layer. Bonding of the backing layer. The product of the invention can not only achieve high shading, but also can achieve high-efficiency charcoal-forming and flame-retardant, and also has good biodegradability. The composite product has environmental friendliness, green environmental protection, no peculiar smell, safety and health, and can be widely used in curtains, tents, In the field of curtains, shower curtains, sunshades, and partition curtains, it can play a flame-retardant shading effect in public places, vehicles and family places.

Description

technical field [0001] The invention relates to the field of flame retardant materials, in particular to a bio-based flame retardant material and a preparation method and application thereof. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for product performance continue to increase. At present, the flame retardant, environmental protection and environmental friendliness of materials have received more and more attention, and relevant standards are constantly being formulated and improved. [0003] In terms of flame retardant, a series of standards have been issued at home and abroad. For example, GB20286-2006 "Flammability Requirements and Labeling of Flame Retardant Products and Components in Public Places", GB8624-2012 "Classification of Combustion Performance of Building Materials and Products", BS5867-2:2008 "Specifications for Curtains and Curtain Fabrics - Part II: Flammability requirements (2008), D...
