Abstract

Belonging to the technical field of coating adhesives, the invention in particular relates to a flame retardant coating adhesive and a preparation method thereof. The flame retardant coating adhesiveis prepared from the following raw materials by weight: 80-120 parts of a waterborne matrix emulsion, 20-35 parts of a polyurethane coating adhesive, 18-22 parts of cyclic phosphate, 10-15 parts of isocyanate, 10-16 parts of tripentaerythritol, 20-26 parts of antimony trioxide, 10-22 parts of ammonium polyphosphate, 8-16 parts of a flame retardant synergist, 5-10 parts of toluene, 5-8 parts of diphenylmethane diisocyanate, 3-8 parts of water-borne blocked isocyanate, 2-5 parts of triphenylmethane triisocyanate and 1-5 parts of trimethylolethane. The flame retardant coating adhesive provided bythe invention has the advantages of good elasticity, corrosion resistance, good flame retardance and the like.

Description

technical field [0001] The invention belongs to the technical field of coating adhesives, and in particular relates to a flame-retardant coating adhesive and a preparation method thereof. Background technique [0002] With the continuous development of the economy, industrial and civilian textiles are increasing rapidly, but at the same time, the fires caused by textiles are also increasing. Therefore, it is very important to carry out flame-retardant treatment on textiles. Therefore, flame-retardant textiles are becoming more and more popular. Flame-retardant coatings are a common flame-retardant finishing technology for textiles. Traditional textile flame-retardant coatings use more halogen-containing flame retardants, which will decompose a large amount of Toxic and harmful fumes. [0003] At present, polyester fabric itself has remarkable characteristics such as good elasticity, not easy to deform, corrosion resistance, and insulation. It is widely used in textiles and ...
