Abstract

The invention discloses a UV-cured flame-retardant waterborne polyurethane adhesive and a preparation method thereof. A formula of the UV-cured flame-retardant waterborne polyurethane adhesive is composed of isocyanate, dihydric alcohol, hydroxyethyl acrylate, a reactive diluent, a flame retardant, a photoinitiator, a catalyst, a polymerization inhibitor, an accelerant, triethylamine, a solvent and deionized water. The preparation method comprises the steps: step 1, selecting raw materials; step 2, preparing waterborne polyurethane acrylate; step 3, preparing waterborne flame-retardant polyurethane acrylate; and step 4, mixing and preparing the finished product; according to the invention, the UV curing technology is introduced into the adhesive industry, the curing efficiency is improved,the energy consumption is reduced, and the adhesive is an aqueous system and meets the requirements of the furniture industry on environmental protection and health; meanwhile, the reactive flame retardant is introduced into a polyurethane structure, stable flame retardance and heat resistance are formed, the prepared adhesive is high in bonding strength, the better the thermal stability and flame retardance of a cured film are, the better the storage stability is, and the wide application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of flame-retardant adhesives, in particular to a UV-cured flame-retardant water-based polyurethane adhesive and a preparation method thereof. Background technique [0002] With the rapid development of people's life, and the requirements for travel comfort are increasing. In the manufacture of various furniture, luggage, and seat cushions for travel vehicles such as airplanes, automobiles, high-speed rail, trains, and ships, the most commonly used resins such as sponges, plastics, wood, and leather are the most commonly used resins. Organic solvent glue. Water-based polyurethane adhesive is an adhesive that uses water instead of organic solvents as the dispersion medium. It retains the characteristics of high strength, low temperature resistance, and wear resistance of traditional solvent-based polyurethane adhesives, and is safe and non-toxic. Harmless and does not pollute the environment. [0003] Howev...
