Example Embodiment

[0021] Example Preparation of water-based anticorrosive coating

[0022] Weigh 0.6 kg of SN-NXZ, 9 kg of sodium polyacrylate, 0.6 kg of polyvinyl alcohol, 0.8 kg of Add 20 kg of water, stir at 200 rpm for 20 minutes, then add 150 kg of AB-EP-20 aqueous epoxy resin emulsion, stir at 800 rpm for 20 minutes, and then transfer to a sand mill at 1200 rpm Sand mill at a rotating speed for 60 minutes, filter with a 100-mesh sieve, add Tego Glide B14841.6 kg to the filtrate, and stir at 100 rpm for 10 minutes to obtain.

Example Embodiment

[0023] Experimental example

[0024] Prepare the waterborne epoxy anticorrosive paint film prepared in Example 1 according to the requirements of the national standard GB 1727-79 "Paint Film Preparation Method". After the substrate is polished and rusted to make the surface clean, it is wiped with absolute ethanol and aired. Dry to keep it dry. When preparing the paint film, the prepared coating is evenly applied on the substrate with a wolf hair brush, and the painted coating is cured at room temperature, and various performance tests are performed after it is dried at room temperature.

[0025] The anti-corrosion performance of the coating is evaluated by visually checking the blistering and shedding of the sample after being immersed in the corrosive medium for a certain period of time under the specified corrosion conditions.

[0026] When conducting the corrosion-resistant medium immersion test, select 3 parallel test panels, and each test panel should be sealed with a 1:1 mixt...

Abstract

The invention relates to water-based anti-corrosion paint, which is prepared from the following ingredients in parts by weight: 120 to 180 parts of water-based epoxy emulsion, 0.2 to 0.8 part of defoaming agent, 5 to 15 parts of dispersing agent, 0.5 to 1 part of thickening agent, 1.5 to 2 parts of flatting agent and 0.6 to 1.5 parts of anti-corrosion agent. The invention also relates to a preparing method of the water-based anti-corrosion paint. The water-based anti-corrosion paint has the excellent anti-corrosion performance, and can be widely used for anti-corrosion effects of material surface layers.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular, the invention relates to a water-based anticorrosion coating and a preparation method thereof. Background technique [0002] my country's transportation, construction, energy and other industries are constantly growing and developing, and various materials are used in the process, and all materials will always be in long-term contact with corrosive or oxidizing air, which may cause Its surface is damaged, and when the material is exposed, its surface is likely to be eroded by sun, rain, ice, snow and fog. As a result, steel rusts, concrete pavements crack and crumble, and wood shrinks. Material corrosion is the most important cause of material waste and energy loss, which causes 20% of global energy and 4.2% of GNP (gross national product) loss every year, and in daily use, many materials will also be damaged In order to prevent or reduce the possibility of scratches, wear and imp...
