Problems solved by technology

[0006] Although water-based epoxy anti-corrosion coatings have many advantages, they also have disadvantages such as long drying time, poor weather resistance, and flash rust due to the water-based system used. Many measures have also been taken in the prior art, but they all have their own shortcomings. question

Abstract

The invention discloses a water-borne anticorrosion epoxy primer and a preparation method thereof. The water-borne anticorrosion epoxy primer comprises a component A and a component B, wherein the component A comprises the following subcomponents in parts by weight: 34-50 parts of water-borne epoxy resin, 0.2-0.5 part of a flash rust preventer, 0.2-0.5 part of an anti-settling agent, 0.2-0.5 part of a wetting agent, 0.5-1.5 parts of a stabilizer, 0.2-0.5 part of a defoaming agent, 0.2-0.5 part of a wetting dispersant, 4-9 parts of iron oxide red, 12-19 parts of micaceous iron oxide, 4-9 parts of composite phosphate, 7-12 parts of talcum powder, 8-15 parts of distilled water and 0.5-2 parts of a nano-sized inorganic filler; the component B comprises the following subcomponents in parts by weight: 43-59 parts of a water-borne epoxy curing agent, 1.5-3 parts of a flash rust preventer and 39-54 parts of distilled water; the component A and the component B are blended according to a weight ratio of (3-7): 1. The water-borne anticorrosion epoxy primer adopts a unique formula and a proportion design; compared with the prior art, the water-borne anticorrosion epoxy primer has the advantage as follows: the overall performance, especially the salt spray resistance, of the water-borne anticorrosion epoxy primer is effectively improved.

Description

Technical field [0001] The invention relates to a waterborne epoxy coating, in particular to an environmentally friendly waterborne epoxy anticorrosive primer; the invention also relates to a preparation method of the waterborne epoxy anticorrosive primer. Background technique [0002] At present, most domestic coating products are organic solvent-based coatings, especially heavy-duty coatings; although solvent-based coatings have superior performance, their VOC content is too high, and they are highly toxic and flammable, causing great damage to the atmosphere and human health. The threat of many cancers, such as skin cancer, has a lot to do with toxic paint. Water-based coatings replace organic solvents with water, greatly reducing the VOC content, and the construction process of water-based coatings has no fire hazard and low toxicity, which is one of the main development trends of anti-corrosion coatings. [0003] Waterborne epoxy resin has become a hot spot in recent years du...
