Abstract

The invention relates to the technical field of chemical paints, particularly relates to an electrostatic spraying type chlorinated rubber anticorrosive paint and a preparation method thereof. The electrostatic spraying type chlorinated rubber anticorrosive paint mainly comprises an anticorrosive paint and a dedicated electrostatic lacquer diluent which are uniformly mixed, wherein the anticorrosive paint comprises a chlorinated rubber solution which comprises chlorinated rubber with new solvent as a main raw material, and the dedicated electrostatic lacquer diluent comprises a conductive agent and a conductive solvent. The electrostatic spraying type chlorinated rubber anticorrosive paint disclosed herein can be used for electrostatic spraying in construction, thus paints are saved, the labor productivity is greatly raised, and safety and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to an electrostatically sprayable chlorinated rubber anticorrosion paint and a preparation method thereof. Background technique [0002] Chlorinated rubber anti-corrosion paint is a product obtained by chlorination after refining natural rubber. It has a regular molecular structure, saturated double bonds, low polarity, and high chemical stability. It can be thickly coated, and the paint film is resistant to acids, alkalis, and It has many advantages such as good corrosion resistance to salt, anti-permeation, quick-drying, construction is not limited by climate, durable and weather-resistant, and easy to maintain. It is widely used in the fields of ships, chemicals, steel structure products, and heavy anti-corrosion engineering. However, the existing chlorinated rubber anticorrosion paint is usually made in a strong polar alcohol solvent system, which has unstable performa...
