| titleOfInvention | Modified delayed coagulation binder and preparation method thereof |
| abstract | The invention provides a modified slow-setting adhesive and a preparation method thereof, wherein the adhesive comprises the following components in parts by weight: 100 parts of bisphenol A epoxy resin, 5-15 parts of diluent, 10-20 parts of low molecular weight polyamide, 1-5 parts of modified fumed silica and 15-30 parts of cement, wherein the modified fumed silica is prepared by modifying the fumed silica by a high molecular surfactant. According to the invention, the gas-phase silica is modified by using the copolymer of the high molecular surfactant, namely acrylic acid or maleic anhydride and alkenyl amide, so that the thixotropic index retention rate of the retarding adhesive is improved, the problems of low-temperature viscosity, high-temperature viscosity and easiness in flowing of the retarding adhesive can be solved under the condition of ensuring that other properties meet the standard, the dosage of filler cement is reduced, and the toughness of the retarding adhesive is improved. Meanwhile, the modified fumed silica and the polysiloxane are unexpectedly found to have a synergistic effect, and the heat distortion temperature of the delayed coagulation binder can be improved by controlling the dosage of the modified fumed silica and the polysiloxane. |
