Water-based antirust paint for steel structure as well as production method thereof

Abstract

The invention provides a water-based antirust paint for a steel structure. The water-based antirust paint comprises the following components in parts by weight: 25-35 parts of an acrylic emulsion, 3-15 parts of pigment, 5-15 parts of an antirust agent, 15-25 parts of filler, 0.15-0.25 part of a flatting agent, 0.15-0.25 part of a dispersant, 0.2-0.4 part of a defoamer, 1.0-1.5 parts of a film-forming agent, 0.3-0.4 part of an anti-flash rust agent, 10-20 parts of deionized water, 0.7-1.3 parts of a neutralizer and 0.3-0.45 part of a thickener. The water-based antirust paint provided by the invention is fast in drying speed: 5-10 minutes for surface dry and within 6 hours for hard dry, so that the coating production efficiency is enhanced. When a product is coated, the paint is just diluted by tap water, so that the coating cost is lowered. The VOC (Volatile Organic Compounds) content is not greater than 85, so that damage to human body during coating is reduced. The salt spray resistance property of the paint can reach over 500 hours, and the corrosion resistance of the paint is strong.

Description

technical field [0001] The invention belongs to the technical field of paints, and in particular relates to a water-based antirust paint for steel structures and a production process thereof. Background technique [0002] With the development of the economy, people pay more and more attention to environmental protection, especially for large-scale steel structure factories, the profit of steel structure is very low now, and the painting is harmful to the painter's body, which leads to a great increase in the cost of steel structure painting. At present, 90% of the steel structure factories in the market still use oily alkyd antirust paint for operation. Oily alkyd antirust paint has a strong smell, slow drying speed, poor salt spray resistance and artificial aging resistance. Larger, it is impossible to build a painting workshop with a better ventilation system, so the painting environment is very harsh, and the cost is still very high.
