Problems solved by technology

However, as an inorganic powder material, its application defects are also obvious, especially in the application of flame retardant textiles, polyphosphate amine has strong hygroscopicity, which will increase the water content of the flame retardant coating of the fabric, resulting in fabric weight increase, the surface is wet and sticky, thereby reducing the strength and other application properties of flame-retardant fabrics
[0004] In order to reduce the hygroscopicity of polyphosphate amine, the commonly used method is to microencapsulate polyphosphate amine, including melamine microencapsulation, isocyanate microencapsulation, silicone oil microencapsulation, melamine formaldehyde microencapsulation and other microencapsulation technologies , but the solubility of these microencapsulated polyamine polyphosphates (g / 100mlH 2 O, 25°C) index is still high, and generally can only be applied to flame retardant of wood, plastic, etc., and cannot meet the requirements of flame retardant finishing of textiles

Abstract

The invention discloses an antiflaming coating adhesive for textiles and a preparation method thereof. The microencapsulation polyphosphoric acid is prepared from the following raw materials in parts by weight: 100-102 parts of crystal phase II polyphosphoric acid amine, 4-4.5 parts of tripolycyanamide, 11-11.5 parts of diphenylmethane diisocyanate, 0.4-0.5 part of triphenyl methane three isocyanate, 5-5.5 parts of dicyclohexyl carbodiimide, 0.5-0.8 part of trimethylolethane, 120-125 parts of acetone and 27-29 parts of methylbenzene; and the antiflaming coating adhesive is prepared from the following raw materials in parts by weight: 200-300 parts of microencapsulation polyphosphoric acid amine, 600-800 parts of a solvent type coating adhesive, 20-30 parts of ring-shaped phosphate FR-CU, and 60-80 parts of antimonous oxide. The antiflaming coating adhesive provided by the invention has the advantage that the hygroscopicity is low, can resist washing and is environment-friendly and is efficient and antiflaming.

Description

technical field [0001] The invention relates to a microencapsulated polyphosphoric amine flame retardant, a flame retardant coating adhesive for textiles using the microencapsulated polyphosphoric amine flame retardant and a preparation method thereof. Background technique [0002] Flame-retardant textiles are commonly used functional textiles, and textile flame-retardant coatings are a common textile flame-retardant finishing technology. This finishing technology essentially uses adhesives to adhere flame retardant components to the surface of textiles. , so as to achieve the overall flame retardant effect of textiles. With the improvement of people's living standards, the requirements for flame-retardant textiles are getting higher and higher. Traditional textile flame-retardant coatings use a large number of halogen-containing flame retardants, and halogen-containing flame retardants will decompose in high temperature environments. Harmful fume, its application is more ...
