Abstract

The invention relates to a liquid solvent-free environmental-protection nano macromolecular textile binding material. The composite binding material adopted in the prior textile industry contains a great amount of harmful organic solvents such as toluene, xylene and methyl ethyl ketone, thereby causing serious environmental pollution and doing harm to human body health. The binding material takes terminal hydroxyl vegetable oil acid performed polymer, vegetable oil and terminal hydroxyl polyatomic alcohol as a matrix, and inorganic nano material as a carrier so as to be reacted with isocyanate, thereby polymerizing the single-composition liquid solvent-free environmental-protection nano macromolecular textile binding material, wherein the terminal hydroxyl vegetable oil acid performed polymer is made through the reaction between terminal hydroxyl vegetable oil acid and small molecular polyatomic alcohol; and the terminal hydroxyl degree of functionality of the terminal hydroxyl vegetable oil acid is of between 2 and 3. The liquid solvent-free environmental-protection nano macromolecular textile binding material has the advantages that: renewable resources are under full utilization; the geometric and structural characteristics of the nano material are brought into play to obtain strong binding power, hydrolysis resistance, excellent heat resistance, ideal low-temperature dimensional stability and high flexibility; the bonding material is nontoxic and harmless and does not have volatile organic solvent, thereby doing no harm to a human body and the environment; and the binding material can realize cold curing, energy conservation and simple and convenient operation.
