Problems solved by technology

At present, many domestic and foreign products on the market can be applied in the field of plastics, rubber and coatings after silane modification or melamine modification, but the application of water-based flame-retardant coatings in textiles does not make the fabric obtain Very good resistance to washing or soaping, and the coating is also resistant to long-term blistering and moisture
[0004] Various methods of coating and modifying APP are mentioned in the existing published patent documents, but they are generally modified by single-layer coating, and the application fields are mainly concentrated in the fields of plastic rubber and coatings, and many of them involve improving their thermal stability. compatibility and even improve the mechanical properties of flame-retardant polymers, but it is still difficult to relate to the specific application of water-based flame-retardant coating adhesives in the textile field
In the textile field, the requirements for water resistance, blistering, and soaping are completely different from those in the fields of plastics, rubber, and coatings. The requirements for soft, dry, smooth and waxy handles are also not mentioned in the fields of plastics, rubber, and coatings. The application performance requirements in the field of textiles are not based on the general outlook of the literature that single-weight modified APP can be applied in the fields of papermaking, wood, textiles and other fields. Without strong chemical or physical forces, APP cannot Get good wash and foam resistance and durable flame retardant properties on fabrics without even a dry hand

Abstract

The invention discloses an aqueous coating adhesive containing multiple coating modified ammonium polyphosphate and applications thereof on fabric finishing. The single modified ammonium polyphosphate can not acquire excellent wash-resisting, immersion-resisting and durable fire retardant performance from the fabric, and can not even obtain dry and comfortable hand feeling. The invention is characterized in that the ammonium polyphosphate, which is modified by melamine, single silane or epoxy resin, is subjected to heating and backflow in an organic alcohol-like solvent, a silane coupling agent capable of being bonded with active groups in the modified ammonium polyphosphate is then added so that the surface of the ammonium polyphosphate experiences multilayer coating and has active hydrogen; the coated ammonium polyphosphate is added with a nonionic surfactant, water, a binder and aqueous closed polyurethane, the aqueous coating adhesive containing the multiple coating modified ammonium polyphosphate is obtained by means of dispersed grinding. The invention is coated on terylene or pure cotton fabrics, thus realizing the cross-linked film forming of the ammonium polyphosphate andthe aqueous closed polyurethane and the aqueous binder, and obtaining waterproof and durable environmentally-friendly fire retardant coating fabric.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a water-based coating glue containing multiple-coated modified ammonium polyphosphate and its application in fabric finishing. Background technique [0002] Ammonium polyphosphate (APP) is an environmentally friendly, halogen-free, high-efficiency and low-toxicity flame retardant. It has been launched in the flame retardant of plastics and coatings, and has certain applications in wood, paper, rubber, and textiles. However, ammonium polyphosphate has strong hydrophilicity and certain water solubility. It has migration ability in flame-retardant substrates, and it is prone to blooming, salting-out and other phenomena. The hydrolysis of ammonium phosphate (APP) leads to the decrease of flame retardancy. [0003] Currently, various technologies are used to modify or coat ammonium polyphosphate (APP), which is an effective way to reduce its water solubility and hygroscopicity, imp...
