Abstract

The invention relates to a flame retardant coating adhesive and application thereof. The flame retardant coating adhesive comprises hydrophobic modified ammonium polyphosphate M-APP, ylate emulsion, cyclic phosphates, pentaerythritol PER and a thickening agent. The flame retardant coating adhesive is applied to flame retardancy of polyester high-speed rail interior textiles; the back of a fabric is coated with the flame retardant coating adhesive in a scrapping mode and baked, and a finished product is obtained. By means of the flame retardant coating adhesive and application thereof, the technical problems that the polyester fabric is low in flame retard efficiency, low in melting and dense in smoke in the combustion process, a great quantity of toxic gas is generated, and the coating fabric absorbs moisture and is sticky are solved.

Description

technical field [0001] The invention belongs to the field of flame retardants, in particular to a flame retardant coating glue and its application. Background technique [0002] The great development in the era of high-speed trains and the advancement of localization have given high-speed rail a broad market prospect, so the diversified demand for environmentally friendly and functional interior textiles is more urgent. Passenger trains running at high speed, due to their closed internal space and relatively large and concentrated combustibles, once a fire breaks out, the fire will burn very fast, the fire smoke will spread rapidly, and soon fill the entire carriage, seriously threatening the lives of people and driving safety. . The poisonous smoke produced by combustion greatly reduces people's visibility and is the biggest threat to casualties. Therefore, the research and development of low-smoke, high-performance, flame-retardant and safe high-speed rail interior texti...
