Abstract

The invention discloses a method for resourceful treatment of waste water from the production of Bic, comprising the following steps: S1: raising the temperature of the waste water containing by-products generated in the production process of Bick to 50°C, distilling under reduced pressure at -0.09MPa, and concentrating until the viscosity of the thick liquid is 500-1000mPa.s at 25°C, and cool down to 30°C; S2: Centrifuge the thick liquid obtained in step S1 to remove salts such as NaCl, and obtain a light yellow viscous polymer material, standby; S3: add light yellow viscous polymer, polyether polyol, crosslinking agent, surfactant, chain extender, catalyst, water in sequence according to the proportion, and mix evenly to obtain component A; S4: add Add a certain amount of curing agent to component A, stir it mechanically immediately, and pour it into the mold immediately after stirring evenly to start foaming, and finally obtain rigid polyurethane foam. The invention can effectively treat the waste water produced by Bick, and can also use its by-products to produce high-quality rigid polyurethane foam, thereby realizing turning waste into wealth and having good application prospects.
