| titleOfInvention | Preparation method for furan nitrogen-free environment protection casting resin adhesive |
| abstract | The invention relates to a preparation method for a furan nitrogen-free environment protection casting resin adhesive. The preparation method is characterized by comprising the specific steps: matching raw materials according to a certain mass part ratio, wherein the raw materials comprise, by mass, 60 parts of furfuryl alcohol, 30-35 parts of polyvinyl alcohol, and 15-20 parts of butyraldehyde; adding the raw materials to a reaction kettle; stirring while adding 15-20 parts by mass of furan resin acid waste water with a concentration of 12% to the reaction kettle, wherein the furan resin acid waste water is adopted as a catalyst; opening a heat source, controlling a temperature to 38-42 DEG C, and carrying out a reaction to generate an alcohol prepolymerization product; further heating to a temperature of 48-52 DEG C, and adding 60-70 parts by mass of furfuryl alcohol to the reaction kettle; closing the heat source, adjusting the PH value to a neutral PH value, adding a coupling agent when the temperature in the reaction kettle is close to 19-21 DEG C, and stirring; and filtering after 1-2 hours to obtain the product. The resin prepared by using the preparation method provided by the present invention has characteristics of good high temperature performance, high strength, low gas evolution, smooth casting surface, and energy source and heat energy saving, wherein solar energy hot water is adopted to heat, such that 100% energy source is saved. |
