Nanometer aluminum silicate composite powder-containing aqueous organic-inorganic hybrid anticorrosive coating and preparation method and using method thereof

Abstract

The invention relates to a nanometer aluminum silicate composite powder-containing aqueous organic-inorganic hybrid anticorrosive coating and a preparation method and a using method thereof, and belongs to the field of fine chemical engineering. The anticorrosive coating comprises the following components as raw materials in parts by weight: 20-35 parts of nanometer aluminum silicate composite powder, 25-42 parts of a hybrid emulsion, 15-32 parts of a pigment, filler and auxiliary agent component and the balance of water, wherein the nanometer aluminum silicate composite powder is prepared bymixing nanometer aluminum silicate powder, nanometer CaCO3 mineral powder, nanometer SiO2 mineral powder and molybdate; and the hybrid emulsion is prepared by mixing an aqueous emulsion, silica sol and triethanolamine. Due to use of various inorganic mineral powder materials in the anticorrosive coating, the cost of a coating product can be significantly reduced; and in addition, coating preparedfrom the coating provided by the invention has higher hardness, toughness, water resistance, heat stability, oxidation resistance and frost resistance than high molecular coating, and has stable performance and high repeatability.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and in particular relates to a water-based organic-inorganic hybrid anticorrosion coating containing nano-aluminum silicate composite powder and a preparation method and application method thereof. Background technique [0002] Water-based coatings have been widely used in the construction industry and home improvement industry due to their environmental protection. Because the VOCs emitted by oil-based paints pollute the atmosphere and harm human health, various relevant departments of the country have issued documents to restrict or prohibit the production and construction of oil-based paints, and actively encourage the production and use of environmentally friendly paints. Among them, water-based industrial coatings are the focus of promotion. However, some common technical bottlenecks of water-based industrial coatings are: poor water resistance, weak adhesion, anti-rust and anti-corrosion prop...

AI Technical Summary

Problems solved by technology

However, some common technical bottlenecks of water-based industrial coatings are: poor water resistance, weak adhesion, anti-rust and anti-corrosion properties are not as good as similar oil-based paints, and since most of the additives used need to be imported, their dosage is also larger than that of oil-based paint systems. The manufacturing cost of water-based industrial coatings is much higher than that of similar oil-based coatings, and they are not supported and accepted by users. Therefore, there is great resistance to the promotion of water-based industrial coatings.

These problems have seriously affected the transformation and healthy development of the waterborne industrial coatings industry
