High-toughness rare earth modified aqueous chlorosulfonated polyethylene anticorrosive paint and preparation method thereof

Abstract

The invention discloses a high-toughness rare earth modified aqueous chlorosulfonated polyethylene anticorrosive paint and a preparation method thereof. The high-toughness rare earth modified aqueous chlorosulfonated polyethylene anticorrosive paint is characterized by being prepared through the following raw materials in parts by weight: 2-3 parts of asbestos fiber, 50-60 parts of chlorosulfonated polyethylene emulsion, 1-3 parts of linoleic acid, 3-6 parts of sodium dodecyl sulfate, 2-4 parts of lanthanum oxide, 20-30 parts of nitric acid solution, 1-2 parts of steel fiber, 3-5 parts of talcum powder, 6-9 parts of ammonium bicarbonate solution, 3-5 parts of titanium dioxide, 5-10 parts of conducting graphite, 3-6 parts of water-borne epoxy resin, 3-6 parts of polyacrylic acid, and 5-10 parts of silane coupling agent KH560. According to the high-toughness rare earth modified aqueous chlorosulfonated polyethylene anticorrosive paint, talcum powder and a rare earth compound are mixed, so that the corrosion resistance, the ageing resistance, the abrasion resistance and the glossiness of the paint can be improved; the static-conducting graphite is added to the paint, so that the paint is excellent in static conducting performance and electromagnetic interference preventing performance; the paint is applicable to protective coating of various equipment; the asbestos fibers, the steel fibers and the like are added, so that the toughness and the impact resistance of the paint are improved.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a rare-earth modified water-based chlorosulfonated polyethylene anti-corrosion coating with good toughness and a preparation method thereof. Background technique [0002] Chlorosulfonated polyethylene anti-corrosion coatings were popularized and applied in the 1980s. With the rapid development of modern industrial level, higher and stricter ability to withstand environmental corrosion has been put forward for anti-corrosion coatings. The anti-corrosion performance of coatings produced by traditional formulas is generally difficult to meet the requirements. In the past, most of the chlorosulfonated polyethylene anti-corrosion coatings were solvent-based, which not only caused a lot of waste of solvents, but also used toxic and volatile solvents, polluted the environment, and did not meet environmental protection requirements, while water-based coatings have clean pro...

The anti-corrosion performance of coatings produced by traditional formulas is generally difficult to meet the requirements

In the past, most of the chlorosulfonated polyethylene anti-corrosion coatings were solvent-based, which not only caused a lot of waste of solvents, but also used toxic and volatile solvents, polluted the environment, and did not meet environmental protection requirements, while water-based coatings have clean process, advanced technology, The advantages of low emission, low energy consumption, safety and harmlessness, therefore, the study of water-based chlorosulfonated polyethylene anti-corrosion coatings has great social and economic benefits

[0003] Cao Hongzhang made a kind of anti-corrosion coating by using rare earth additives and chlorosulfonated polyethylene in "Research on the Performance of Waterborne Chlorosulfonated Polyethylene Anti-corrosion Coatings Modified by Rare Earth Additives", but as an anti-corrosion coating for various equipment, it is still It has the disadvantages of lack of static conduction function and insufficient anti-corrosion performance
