Problems solved by technology

In the textile field, traditional intumescent flame retardants are not widely used. If traditional intumescent flame retardants composed of ammonium polyphosphate (APP) and pentaerythritol or dipentaerythritol and melamine (MEL) are used on fabrics, The fabric is not resistant to washing, blisters, and migration. Under the action of light, heat, humidity, and external mechanical forces, the flame retardant will be lost or degraded, and the flame retardant performance will easily decline.
[0003] In order to improve the water resistance of intumescent flame retardants, a large number of documents and patents have proposed various methods of coating modified ammonium polyphosphate, but ammonium polyphosphate is only one of the components of flame retardants, and coating modified ammonium polyphosphate Finally, for pentaerythritol and dipentaerythritol with certain water solubility and melamine that dissolves very slightly in water, there will still be problems of not being resistant to blisters and washing, and not resistant to migration

Abstract

The invention discloses an intumescent flame retardant coating gum and the application thereof on fabric finishing. When the traditional intumescent flame retardant is applied to fabric, the fabric is not resistant to water rinse, water immersion or transfer, the flame retardant can lose or degrade under the action of luminous rays, heat, moisture and mechanical external force, and the flame retardant properties are reduced. The intumescent flame retardant coating gum comprises a flame retardant coating base gum and a carbon source, and is characterized in that the flame retardant coating base gum is prepared by mixing ammonium polyphosphate, melamine and 4A zeolite, adding organic alcohol, coating the mixture by more than two silane coupling agents for modification, drying the mixture after removing the organic alcohol to obtain a composite flame retardant, adding water, a non-ionic surface active agent, a binding agent and a cross-linking agent to the composite flame retardant, and grinding and dispersing the mixture; the carbon source is aqueous polyacrylic ester containing hydroxyl groups or aqueous polyurethane containing hydroxyl groups or a modifier of the former two. The invention obviously improves the performance of the flame retardant coating gum on flame retardant fabric for resistance to water rinse, transfer, light, heat and friction.
