Low-shrinking rate rare-earth modified waterborne chlorosulfonated polyethylene anticorrosive paint and preparation method thereof

Abstract

The invention discloses a low-shrinking rate rare-earth modified waterborne chlorosulfonated polyethylene anticorrosive paint and a preparation method of the low-shrinking rate rare-earth modified waterborne chlorosulfonated polyethylene anticorrosive paint. The low-shrinking rate rare-earth modified waterborne chlorosulfonated polyethylene anticorrosive paint is characterized in that the low-shrinking rate rare-earth modified waterborne chlorosulfonated polyethylene anticorrosive paint is prepared from the following raw materials by weight: 2-4 parts of a quartz powder, 50-60 parts of a chlorosulfonated polyethylene emulsion, 1-2 parts of a mica powder, 4-7 parts of sodium dodecyl sulfate, 2-4 parts of lanthanum oxide, 20-30 parts of a nitric acid solution, 2-3 parts of a silica gel powder, 3-5 parts of a talcum powder, 6-9 parts of an 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 a silane coupling agent KH560. The talcum powder and the rare earth compound are combined to improve the corrosion resistance, the ageing resistance, the wear resistance and the glossiness of the paint; the static electricity conductive graphite is added in the paint, so that the paint achieves the excellent properties of static electricity conduction and protection against electromagnetic interference, the obtained paint is suitable for the protective coating of various equipment; by adding the quartz powder and the like, the shrinking rate of the paint is reduced.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a low-shrinkage 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
