Radiation-proof rare earth modified waterborne chlorosulfonated polyethylene anticorrosive paint and preparation method thereof

Abstract

The invention discloses radiation-proof rare earth modified waterborne chlorosulfonated polyethylene anticorrosive paint and a preparation method thereof. The radiation-proof rare earth modified waterborne chlorosulfonated polyethylene anticorrosive paint is characterized by being prepared from, by weight, 1-2 parts of nanosilicon dioxide, 50-60 parts of chlorosulfonated polyethylene emulsion, 1-2 parts of lead powder, 3-6 parts of sodium dodecyl sulfate, 3-5 parts of lanthanum oxide, 20-30 parts of salpeter solution, 2-4 parts of graphene oxide, 3-5 parts of talcum powder, 6-9 parts of ammonium bicarbonate solution, 3-5 parts of titanium dioxide, 5-10 parts of conductive graphite, 3-6 parts of waterborne epoxy resin, 3-6 parts of polyacrylic acid and 5-10 parts of silane coupling agent KH560. The talcum powder and a rare earth compound are combined, and the corrosion resistance, aging resistance, abrasion resistance and glossiness of the paint are improved; the static conductive graphite is added into the paint, so that the paint has excellent static conductive and electromagnetic interference resisting performance, and the obtained paint is suitable for protective coating of various kinds of equipment; by adding the lead powder and the like, the radiation-proof function of the paint is achieved.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a radiation-proof rare-earth modified water-based chlorosulfonated polyethylene anti-corrosion coating 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 process...

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
