Abstract

The invention relates to an acrylic acid modified chlorinated rubber waterborne coating suitable for a marine environment and a preparation method of the acrylic acid modified chlorinated rubber waterborne coating. The coating composition is prepared from a modified acrylic acid modified chlorinated rubber waterborne emulsion component and a color paste component, wherein the modified acrylic acid emulsion component is prepared from the following components in parts by weight: 34-40 parts of modified acrylic acid resin, 15-17 parts of closed type aliphatic isocyanate curing agent and 44-52.2 parts of deionized water. The coating provided by the invention is a waterborne double-component coating, is convenient to coat and environmentally friendly to use and is safe; a board surface is smooth and bright and is good in decorative effect; a coating layer has the advantages of excellent mechanical performance, acid resistance performance and alkaline resistance performance, very excellent weather resistance performance and corrosion resistance performance and can be used for protecting and coating the surface of a steel structure in a marine corrosion environment; the prepared coating is simple in preparation operation technology, uniform in dispersion of various components and good in stability.

Description

[technical field] [0001] The invention relates to an acrylic chlorinated rubber water-based paint, in particular to an acrylic modified chlorinated rubber water-based paint suitable for marine environments and a preparation method thereof. [Background technique] [0002] Low-carbon environmental protection is the trend that is being pursued in today's society. Water-based coatings and their products meet the requirements of low-carbon environmental protection, so there is great potential for development. Compared with traditional solvent-based coatings, water-based coatings have the characteristics of environmental protection and excellent performance, and have become the mainstream of the development of the coatings industry. The surface of the steel structure in the existing marine corrosive environment is coated with synthetic resin coatings. The disadvantages are that the salt spray resistance and light aging resistance are not good, and the coating is prone to corrosion...
