Abstract

The invention is applicable to the field of coatings, and provides a waterborne composite resin and a preparation method thereof. The composite resin comprises components such as a resin monomer, modified nano montmorillonite, an organic silicon monomer, an initiator and water. According to the composite resin, multiple parallel layers formed filling the resin monomer by using the modified nano montmorillonite force gas to escape from a polymer through a 'tortuous channel', and then a complex blocking layer is formed for the gas and steam; meanwhile, an emulsifier with hydrophilic groups is not used, so that a demulsification effect of an acrylic emulsion under a high-speed shear force is solved, and the water resistance and corrosion resistance of a coating prepared from the resin are improved.

Description

technical field [0001] The invention belongs to the field of water-based paint, in particular to a water-based composite resin and a preparation method thereof. Background technique [0002] Traditional metal surface treatment often uses solvent-based coatings, which not only cause serious environmental pollution, but also cause great harm to human health. At the same time, there are safety hazards such as flammability and explosion during construction, storage, and transportation. Based on the awareness of energy saving and environmental protection, metal surface treatment is gradually developing in the direction of non-toxic and water-based. [0003] The market share of water-based anti-corrosion coatings in Japan, Europe and the United States has exceeded 60%, while the proportion in my country is obviously low. With the improvement of technology and formula, water-based metal protective coatings are the development direction and trend of the coatings industry . However,...
