Expansion type flame-retardant coatings glue and use thereof in textile finishing

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.

Description

Technical field

[0001] The invention relates to the field of textile auxiliaries, in particular to an intumescent flame-retardant coating glue and its application in fabric finishing. Background technique

[0002] Intumescent flame retardants have been widely used in the field of coatings, and they have also been explored and promoted in plastics. In the textile field, traditional intumescent flame retardants are not widely used. If traditional intumescent flame retardants with ammonium polyphosphate (APP) and pentaerythritol or dipentaerythritol and melamine (MEL) as components are applied to fabrics, The fabric is not resistant to washing, blisters, and even less resistant to migration. Under the action of light, heat, humidity, and mechanical external forces, the flame retardant will be lost or degraded, and the flame retardant performance will easily decrease.
