preparation example Construction
[0016] The key to the preparation method of the furan nitrogen-free environmental casting resin adhesive is that the specific steps of the preparation method include:
[0017] a. Proportioning raw materials according to the following parts by mass, 60 parts of furan methanol, 30-35 parts of polyvinyl alcohol, 15-20 parts of butyraldehyde;
[0018] b. Add the above raw materials into the reaction kettle, and while stirring, add 15-20 parts of furan resin acid waste water with a concentration of 12% in the reaction kettle as a catalyst;
[0019] c. Turn on the heat source, and control the temperature at 38-45°C to react to generate alcohol prepolymerization products;
[0020] d. Further heat up to 48-58°C, and then add 60-70 parts of furan methanol to the reaction kettle;
[0021] e. Turn off the heat source, adjust the PH value to be neutral, add 0.1-0.2 parts of coupling agent when the temperature in the reaction kettle reaches room temperature and stir, and filter the impuri...
