Abstract

The invention discloses a water-based heavy-duty single-component on-rust primer, and a preparation method and application thereof. The water-based heavy-duty single-component on-rust primer is composed of deionized water, a main conversion agent, an auxiliary conversion agent, a penetrant, a film forming assistant, an antifreezing agent, a preservative, a thickener, a filler, a defoaming agent, a dispersing agent, a pH regulator, a film forming material and a substrate wetting agent. The temperature of the used substrate can not be too high, the humidity can not be greater than 85%, the one-time spray coating can not be too thick, and the position for electric welding is reserved. The product is stored at 5-40 DEG C in a ventilating cool dry place, and the construction temperature is preferably 10-40 DEG C. The primer can be applied by brush coating, roller coating, air spraying or airless spraying, the particular mode can be selected according to the on-site construction environment and climate conditions, and brush coating and airless spraying are suggested if conditions permit.

Description

technical field [0001] The invention belongs to the field of chemical coatings, and in particular relates to a water-based heavy-duty anti-corrosion single-component rust-carrying primer and a preparation method and application thereof. Background technique [0002] The current use of water-based anti-corrosion coatings in the field of heavy-duty anti-corrosion is still very low. The reasons are complex and multifaceted: 1. Some users are more conservative and unwilling to try coating products based on new technologies. 2. The price of solvent-based coatings is relatively cheap, but the amount of VOC emissions is large, causing serious environmental pollution. However, there are few environmental protection regulations that restrict its use, which cannot effectively restrict its use. 3. The price of water-based coatings is high, and the performance in some aspects is not ideal, and there are certain limitations in use. However, the benefits of using water as a solvent and t...
