Abstract

The invention provides a preparation process for polyurethane resin composite glue used for a reflective coat. The preparation process comprises the following steps: mixing a vinyl acetate-ethylene copolymerized emulsion with cationic polyester type waterborne polyurethane resin, then respectively adding bentonite, benzoate, a cationic thickening agent and a polyether antifoaming agent in above-mentioned parts by weight, and carrying out stirring until raw materials are completely mixed; then adding 4 to 5 parts of an isocyanate curing agent, setting a temperature to be 80 to 85 DEG C, carrying out a reaction for 1 to 2 h, adding 10 to 15 parts of an organic solvent, when the temperature is reduced to 75 DEG C after the organic solvent is added, adding an organic tin catalyst with a weightaccounting for 0.05 to 0.1% of the weight of polyurethane, and allowing remained isocyanate group to be completely reacted; after the reaction is stabilized, adding a stabilizing auxiliary agent; andcarrying out proofing and high-temperature washing testing.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a preparation process of polyurethane resin composite glue for reflective clothing. Background technique [0002] Reflective clothing is made of reflective materials embedded in the main part of clothes or vests. It is a personal safety product used at night or in bad weather, and it can better protect the staff in outdoor work. It is suitable for road workers, traffic and road administration departments, road command personnel, police, cleaners, etc. Its high reflective light plays a warning and eye-catching role to protect the safety of personnel. [0003] The polyurethane resin used in reflective clothing is a composite glue used to bond fabrics and reflective materials, and after bonding, the clothes should have super high temperature resistance and water washability. At present, the existing products in the market are difficult to achieve this performance index well...
