Problems solved by technology

Although intumescent flame retardants have the advantages of being halogen-free, low-smoke, low-toxicity, anti-melt droplets and non-corrosive gases, they are not as good as bromine-antimony flame-retardant systems in terms of flame-retardant efficiency and water-washing resistance.

Abstract

The invention discloses a brominated epoxy resin-containing bromine-phosphorus synergistic flame-retardant coating composition which comprises the following raw materials in parts by weight: 20 to 50 parts of a film-forming agent, 2 to 15 parts of brominated epoxy resin, 3 to 10 parts of bromotriazine, 10 to 40 parts of a phosphorus-containing flame retardant, 1 to 15 parts of pigment filler, 0.5 to 10 parts of a water-based paint additive and 20 to 50 parts of water. According to the brominated epoxy resin-containing bromine-phosphorus synergistic flame-retardant coating composition provided by the invention, macromolecular bromotriazine and brominated epoxy resin are introduced into a traditional P-N intumescent composite flame-retardant system (IFR), so that flame-retardant synergy of Br, P and N is realized, and the water resistance and the flame-retardant effect are excellent.

Description

technical field [0001] The invention relates to a bromine-phosphorus synergistic flame retardant coating composition containing brominated epoxy resin, a method for preparing the flame retardant coating composition, and a flame retardant fabric prepared with the flame retardant coating composition. Background technique [0002] Public safety is the cornerstone of national security and social stability. Fire is one of the major disasters that threaten public safety, causing a large number of casualties and huge economic losses every year. Textiles are an integral part of everyday life and can be found, for example, in curtains, fabrics, furniture and car interiors, toys, packaging materials and many other applications. According to the investigation of fire accidents, a considerable part of the fires are caused by textiles and interior decorations. China is the largest textile manufacturer in the world. In 2013, China's total textile exports reached 284.1 billion US dollars...
