The T/ZZB 1945-2020 standard specifies the technical requirements and performance indicators of water-based flame retardant coatings for upholstered furniture. The standard aims to provide an environmentally friendly and effective flame retardant coating solution to ensure that upholstered furniture can delay the spread of fire and improve the safety of furniture in the event of a fire. The standard covers the composition, physicochemical properties, flame retardant performance and test methods of the coating, and requires the coating to have good adhesion, durability and environmental friendliness in practical applications. Compared with traditional solar-based paints, water-based paints have the advantage of low VOC emission, meet the requirements of green environmental protection, and are suitable for the painting and fire protection treatment of upholstered furniture. This standard provides a standardized technical basis for furniture manufacturers to help improve the mass and safety of products.
