Abstract
The invention discloses an inorganic zinc-rich anticorrosive paint. The zinc-rich paint is an anticorrosive powder paint which is high in content of zinc powder, thin in film and excellent in performance and is an excellent environment-friendly paint. The paint disclosed by the invention is mainly prepared from the following raw materials in parts by weight: 18-25 parts of solid sodium water glass, 10-15 parts of superfine slag powder, 15-25 parts of metakaolin, 2-5 parts of nano titanium dioxide, 1-5 parts of nano zinc oxide, 1-5 parts of nanosilicon dioxide, 0.5-1 part of a dispersant, 1.1-2.0 parts of a defoamer and 30-40 parts of zinc powder. By using an alkali-based geopolymer as a main film forming matter and the zinc powder as a sacrificial anode, the paint prepared by the invention is a dried paint which is packaged in dry powder. During use of the paint, water is just added in proportion to uniformly stir. The paint disclosed by the invention is abundant in source of raw materials, green and environment-friendly and advanced and pollution-free in preparation process. The prepared paint has the advantages of good water resistance and corrosion resistance, zero VOCs, zero hazardous air pollutants (HAPs), high solid content, low requirement on bottom treatment of metals, simple and convenient construction and the like.
Description
Technical field
What the present invention relates to is a kind of inorganic zinc-rich protective system, particularly be a kind of base ground polymers base inorganic zinc-rich protective system, belong to new material technology field.
Background technology
Along with greatly developing of China's industry, industrial coating usage quantity is increasing, ends 2013, nearly 10000 of coating industry enterprises of China, annual production exceedes 1,300 ten thousand tons, more than approximately 55% is wherein industrial coating, but major part belongs to traditional high low value-added product of environmental hazard.Traditional industry coating is high containing the toxic gas volume of volatile, not only has a strong impact on China's physical environment, also workmen's physical and mental health is caused to serious threat.Green, environmental protection, the abundant coating of raw material sources become the development trend of industrial antisepsis coating, " inorganic environment-friendly Water-borne modification " is the focus of paint development, zinc-rich paint is exactly one wherein, zinc-rich paint is a kind of anti-corrosive powder paint, zinc content is high, film is thin, and excellent performance is a developing direction of environmental protection coating material.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of inorganic zinc-rich protective system, this coating has the advantage such as high solids content, water-fast good, antiseptic property is good, the rich zinc industrial antisepsis of the aqueous inorganic coating of zero VOCs, zero hazardous air pollutants (HAPs), with low cost, not high to metal back layer processing requirements, easy construction, overcomes that the cost that present same type of material exists is higher, poor water resistance, substrate surface treatment require high, the unsettled problem of acid and alkali-resistance.
Above-mentioned technical problem is achieved through the following technical solutions: a kind of inorganic zinc-rich protective system, is mainly made up of following weight part proportioning: solid sodium silicate 18-25 part, slag micropowder 10-15 part, metakaolin 15-25 part, nano titanium oxide 2-5 part, nano zine oxide 1-5 part, nano silicon 1-5 part, dispersion agent 0.5-1 part, defoamer 1.1-2.0, zinc powder 30-40 part;
