The company won a national invention patent authorization
Recently, the invention patent "a waterborne epoxy resin emulsion containing graphene" and its preparation method have been authorized by the State Intellectual Property Office, and the patent number is ZL201710894372.7.
The invention uses in situ polymerization to prepare polyethylene glycol / graphene composite material, so that graphene can be dispersed evenly and anchored in polyethylene glycol matrix, which solves the problem of poor dispersion and poor compatibility of graphene in emulsion, and obtains waterborne epoxy emulsion with uniform dispersion of graphene. The waterborne epoxy resin emulsion containing graphene has good centrifugal, dilution and storage stability. Compared with the traditional epoxy resin, the emulsion has the advantages of low cost, safety, environmental protection, and innocuity, and is applied in anticorrosive coatings with stronger corrosion resistance and adhesion, good impact resistance and easy construction.
This national invention patent provides a new preparation method for the company's graphene application in the paint field, strengthens the existence of the company's reserve technology, provides the company with technology accumulation and valuable experience for the development of other graphene application products, further improves the protection of intellectual property rights, and has a positive impact on the consolidation of the company's core competitiveness. So far, Xiamen kaina has applied for more than 50 patents related to graphene and graphene, and has obtained 30 invention patents and 3 utility model patents.
