Flat textile substrate with at least partial fire protection coating, method for its production and uses thereof

The patent applies composite materials by combining multiple flame retardant substances (phosphorus-based, phosphorus-nitrogen-based, and inorganic flame retardants) with specific binders (starch-based and plastic-based binders) to create a coating composition that achieves fire class A2. This composite approach allows the synergistic interaction of different flame retardant mechanisms while maintaining coating integrity and adhesion to the textile substrate.

The patent employs parameter changes by precisely controlling the weight ratios of components in the coating composition (0.5-10% starch-based binder, 10-50% inorganic flame retardant, 0.5-20% phosphorus-based flame retardant, 1-20% plastic-based binder) and optimizing application parameters (coating weight, drying conditions) to achieve the specific fire class A2 performance requirement.

The patent merges multiple flame retardant components and binder systems into a single integrated coating composition that can be applied in one step. The combination of starch-based and plastic-based binders with multiple flame retardant types creates a unified system that simplifies the application process while achieving superior fire protection performance.

The patent achieves homogeneity by formulating a uniform coating composition where all components (binders, flame retardants, and additives) are distributed evenly throughout the aqueous medium. This homogeneous mixture ensures consistent flame retardant performance across the entire textile substrate surface and simplifies the coating application process.

The patent optimizes the concentration parameter of inorganic flame retardants within the specific range of 10-50% by weight, balancing flame retardant effectiveness with coating weight considerations. This parameter optimization ensures sufficient fire protection while avoiding excessive weight gain and potential stiffness issues that would result from higher concentrations.

The patent uses composite materials by combining inorganic flame retardants with organic binders (starch-based and plastic-based) to create a balanced coating system. The binders provide flexibility and adhesion while the inorganic flame retardants provide fire protection, achieving a harmonious balance between weight, flexibility, and flame retardant effectiveness.
