Synthetic method of single-component waterborne epoxy emulsion

The invention relates to the technical field of preparation of water-based epoxy emulsion, in particular to a synthetic method of single-component waterborne epoxy emulsion. The invention develops thewaterborne single-component epoxy emulsion with excellent properties in all aspects. The emulsion has nano particle size and high colloid dispersion stability, and can participate in paint grinding and dispersion. A waterborne single-component epoxy coating prepared by the scheme has excellent hardness, adhesive force, water resistance, salt fog resistance, acid and alkali resistance and the like, and the performance of the coating is far superior to that of foreign products of the same type; and the product has excellent bonding performance, so that the product can also be used in the fieldof bonding. 本发明涉及水性环氧乳液制备技术领域，具体地说，涉及一种单组份水性环氧乳液的合成方法。本发明开发一种各方面性比较优越的水性单组份环氧乳液。该乳液具有纳米粒径，高胶体分散稳定性，可参与涂料研磨分散。用此方案制得的水性单组分环氧涂料具有极佳的硬度，附着力，耐水性，耐盐雾性，耐酸碱等性能，性能远优于国外同类型产品；由于此类型产品具备优异的粘结性能，也可也用于粘接领域。
