Abstract

The invention relates to an epoxy resin antirust paint and a preparation method thereof, belonging to the technical field of polymer materials. The epoxy resin antirust paint of the present invention comprises the following raw materials in parts by weight: 40-60 parts of E-51 epoxy resin, 10-20 parts of polybutadiene, 100-200 parts of cyclohexanone, silane coupling 3-5 parts of aluminum stearate, 5-12 parts of aluminum stearate, 2-9 parts of calcium chromate, 5-19 parts of diatomaceous earth, 12-21 parts of zinc phosphochromate, 3-10 parts of potassium polymethacrylate , 30-50 parts of titanium dioxide, 10-20 parts of pigment, 30-50 parts of curing agent. The epoxy resin antirust paint of the present invention adopts E-51 epoxy resin, cooperates with other components, can solidify well at room temperature, and curing speed is faster, and according to the characteristic of functional coating, climate characteristic, anticorrosion coating construction The characteristics of the performance requirements meet the requirements of the validity period of the anti-corrosion protection.

Description

technical field [0001] The invention relates to an antirust paint and a preparation method thereof. More specifically, the invention relates to an epoxy resin antirust paint and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] In the natural environment, metals such as steel are in an unstable state and are susceptible to corrosion. How to protect metals such as iron and steel so that they can function, prevent corrosion, and prolong service life is an important content of anti-corrosion research. Research and development, functional heavy-duty anti-corrosion coatings are more and more popular. [0003] The State Intellectual Property Office published an invention patent with the publication number CN103360909A on 2013.10.23 and titled "A Waterborne Epoxy Antirust Paint and Its Preparation Method". The patent relates to a waterborne epoxy antirust paint and its The preparation method, the antirust paint is a...
