Environment-friendly flame-retardant textile printing coating and preparation method thereof

Abstract

The invention discloses an environment-friendly flame-retardant textile printing coating and a preparation method thereof. The coating comprises an adhesive, a cross-linking agent, a flame retardant and a catalyst; and the coating is prepared from the following components in parts by weight: 45 to 55 parts of the adhesive, 20 to 25 parts of the cross-linking agent, 15 to 20 parts of the flame retardant, 1 to 5 parts of reinforced fibers and 8 to 12 parts of the catalyst. The environment-friendly flame-retardant textile printing coating provided by the invention is simple in composition, environmentally friendly and good in flame retardant property, the oxygen index is remarkably improved, and after the coating is coated on the surface of a fabric, the fabric can have excellent self-extinguishing property, and is low in smoke amount and non-toxic in the combustion process.

Description

technical field [0001] The invention belongs to the technical field of textile coatings, in particular to an environment-friendly flame-retardant textile printing coating. Background technique [0002] Flame retardant coating is a kind of characteristic coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. The flame retardants of existing flame retardant coatings are halogen flame retardants, which will produce toxic and harmful substances such as dioxin during combustion, causing environmental pollution and gradually being restricted in use, and halogen flame retardants The decomposition temperature of the agent is relatively low, and the amount of smoke is large. When a fire breaks out, it will cause a large amount of dense smoke to suffocate people. China Railway Industry Standard TB / T3237-2010 Fire Retarda...

Problems solved by technology

The flame retardants of existing flame retardant coatings are halogen flame retardants, which will produce toxic and harmful substances such as dioxin during combustion, causing environmental pollution and gradually being restricted in use, and halogen flame retardants The decomposition temperature of the agent is relatively low, and the amount of smoke is large. When a fire breaks out, it will cause a large amount of thick smoke to suffocate people.

China Railway Industry Standard TB/T3237-2010 Fire Retardant Technical Conditions for Interior Materials for EMUs requires that the oxygen index of GB/T5454-1997 textile combustion performance test must reach more than 32%, and the textile fabrics for seat covers for EMUs are flammable. Therefore, it is necessary to coat the surface of the seat cover textile fabric with a flame retardant coating. Since the existing flame retardant coating has poor flame retardancy, in order
