Abstract

The invention relates to the field of heavy anti-corrosion coatings, in particular to a water-based heavy anti-corrosion coating containing water-based modified chlorinated polyether emulsion and a preparation method of the water-based heavy anti-corrosion coating. In percentage by weight, a component A of coating comprises the following raw materials: 52-59% of water-based modified epichlorohydrin emulsion, 4-8% of superfine barium sulfate, 3-6% of mica powder, 2-6% of zinc phosphate, 1-3% of aluminum zinc orthophosphate, 0.1-0.5% of a thickening agent, 0.1-0.2% of a wetting agent, 0.3-0.5% of a defoaming agent, 0.1-0.4% of a dispersing agent, 0.01-0.05% of a flash rust inhibitor, 0.05-0.1% of an anti-settling agent, 0.05-0.1% of a flatting agent, 1-5% of a coalescing agent, 4-8% of filler 1-3% of silica powder, and with the remainder of water ; a component B comprises 50% of a curing agent and 50% of water; and the weight ratio of the component A to the component B is 1: (1-1.5). The water-based heavy anti-corrosion coating containing the water-based modified chlorinated polyether emulsion is prepared, the prepared water-based heavy anti-corrosion coating is high in flexibility and impact resistance, can be rapidly cured at normal temperature, is high in adhesive force with a base material, can keep a lasting salt spray resistance protection effect, and has a wide application prospect.

Description

technical field [0001] The invention relates to the field of heavy-duty anti-corrosion coatings, in particular to a water-based heavy-duty anti-corrosion coating containing a water-based modified chlorine ether emulsion and a preparation method thereof. Background technique [0002] Anti-corrosion coatings are generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, which are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; A type of anti-corrosion coating that achieves a longer protection period than conventional anti-corrosion coatings. The main difference between heavy-duty anti-corrosion coatings and conventional anti-corrosion coatings is that they have higher technical content and greater technical difficulty, involving technological progress and product development in many aspect...
