Efficient low-smoke flame-retardant textile coating adhesive and preparation method thereof

Abstract

The invention discloses an efficient low-smoke flame-retardant textile coating adhesive which consists of the following raw materials in parts by mass: 50-70 parts of water-based acrylic emulsion, 25-40 parts of a phosphorus-nitrogen flame-retardant additive, 4-10 parts of a nitrogen flame-retardant additive, 3-8 parts of a flame-retardant synergist, 1-5 parts of a thickening agent and 10-20 parts of a solvent. The invention also discloses a preparation method of the efficient low-smoke flame-retardant textile coating adhesive, and the preparation method comprises the following steps of (1) adding the water-based acrylic emulsion and deionized water into a dispersion kettle, starting stirring and mixing; (2) adding the phosphorus-nitrogen flame-retardant additive, the nitrogen flame-retardant additive and the flame-retardant synergist into the dispersion kettle in sequence, and uniformly mixing and stirring; (3) adding the thickening agent into a reaction kettle, fully stirring uniformly, and filtering to obtain a finished product. The coating adhesive disclosed by the invention has the advantage of low release of corrosive gas and toxic gas, and has good flame retardant property and good storage stability.

Description

technical field [0001] The invention relates to a high-efficiency low-smoke flame-retardant fabric coating glue and a preparation method thereof. Background technique [0002] As the population of modern metropolises becomes denser and there are more and more high-rise and underground buildings, it becomes more and more difficult to put out fires. In order to reduce the occurrence of fires and reduce fire hazards, the development of flame-retardant products including flame-retardant textiles On the agenda, flame retardant finishing of textile materials is more important. [0003] my country's development of flame-retardant textiles is relatively late, and most traditional flame-retardant textiles are mainly based on bromine-antimony flame retardants. To meet the smoke density level and smoke toxicity level, Chinese Patent Application No. 200810204199.4 discloses a preparation method of high-performance flame-retardant polyester interior textiles, but the resulting product ha...
