Abstract

The invention discloses inflaming retarding water-tolerant polyurethane tackiness agent which is characterized by comprising following components by weight ratio: 88%-92% hydroxyl polyurethane resin, 5.5%-10% isocyanate group (NCO) enclosed type diisocyanate-trimethoprim (TMP), 1.5%-2.5% sodium dodecyl sulfate and 0.5%-1.5% phosphonolipid fire retardant thiamine pyrophosphate (TPP). The invention further discloses a preparation method of the inflaming retarding water-tolerant polyurethane tackiness agent. NCO enclosed type diisocyanate-TMP addition product aqueous dispersion is adopted, reaction of self de-enclosing NCO perssad with hydroxyl-terminated prepolymer is utilized to achieve solidification, and a strong chemical bond is formed to enable the tackiness agent to have the advantages of being strong in binding power, good in water tolerance, washable, free-falling, sun-proof, good in thermal endurance, endurable in chemical products and the like. Grade of products is greatly improved, simultaneously, the inflaming retarding water-tolerant polyurethane tackiness agent is simple in use, convenient to operate, environment-friendly, non-toxic, and environment-pollution-free, has inflaming retarding function and no volatile organic compounds (VOC) discharging, and is beneficial to protecting environment and health of using and production persons.

Description

technical field [0001] The invention relates to the technical field of chemical products used in textile manufacturing, in particular to a flame-retardant and water-resistant polyurethane adhesive and a preparation method thereof. Background technique [0002] There are many types of textile hot stamping products on the market, and there are many inferior products, which are not washable, have insufficient adhesion for patterns, and poor chemical resistance. After repeated washing or strong washing, the printing is easy to discolor and fall off; at the same time Textile products are generally flammable and other problems. [0003] With the improvement of people's living standards and the increase of environmental awareness, water-based polyurethane adhesives are widely used because they do not contain organic solvents, are non-polluting, safe, non-toxic, and environmentally friendly compared with oily polyurethanes. However, the current water-based polyurethane adhesives ge...
