Abstract

The invention discloses a water-based asphalt anticorrosive paint which is prepared from the following raw materials in parts by weight: 65-90 parts of anticorrosive emulsified asphalt, 5-12 parts of acrylic emulsion, 5-12 parts of styrene-butadiene latex, 0.1-0.5 part of de-foaming agent, 1-3 parts of coalescing agents, 0.5-1 part of flatting agent, 0.1-0.2 part of anti-rusting agent and 0.3-1 part of thickening agent. The water-based asphalt anticorrosive paint has high stability, water resistance and weather fastness and has the characteristics of high drying speed, environmental protection and high efficiency.

Description

technical field [0001] The invention relates to a water-based asphalt anticorrosion paint. Background technique [0002] Petroleum asphalt has good adhesion, anti-aging and anti-corrosion capabilities, and has been used as an anti-corrosion material for a long time. It is one of the most widely used materials in anti-corrosion engineering at home and abroad because of its advantages of easy availability of raw materials and low price for anti-corrosion engineering. The loss caused by metal corrosion is very serious, and coating anti-corrosion coating is one of the main methods to prevent metal corrosion. [0003] At present, the vast majority of anti-corrosion coatings at home and abroad are mainly solvent-based coatings, which contain a large amount of organic volatiles, most of which are flammable and explosive toxic substances, which not only pollute the environment, waste energy, but also seriously It endangers the health of construction workers and brings multiple haz...
