Acid and alkaline resisting aqueous nano-paint and preparation thereof

Abstract

The invention relates to acid and alkali resistant water-based nanometer paint and a preparation method thereof. The paint comprises the following components by weight percentage: 20 to 25 percent of elastic emulsion, 0.5 to 1 percent of wetting agent, 0.7 to 1.2 percent of dispersant, 0.3 to 0.8 percent of foam killer, 5 to 10 percent of film forming additive, 3 to 6 percent of thickening agent, 25 to 30 percent of light calcium carbonate, 16 to 20 percent of talcum powder, 10 to 15 percent of titanium pigment, 0.25 to 0.3 percent of mildew preventive, 4 to 12 percent of rosin phenolic resin, 0.5 to 2 percent of sodium dihydrogen phosphate, and the balance being water. The paint can resist alkali, can also resist acid, and resist the erosion of acid and alkali substances inside and outside wall bodies.

Description

technical field [0001] The invention relates to a nano paint composition and a preparation method thereof, in particular to an acid and alkali resistant water-based nano paint and a preparation method thereof. Background technique [0002] With the development of industrialization, the pollution of the atmosphere is becoming more and more serious. The paint painted in the open air is easily corroded, and the life of the paint is short, so it needs to be painted frequently. At present, the paints used by people mainly include acid enzyme paint and nitro paint And baking varnish, can not achieve the purpose of acid and alkali resistance. Wall cement contains soluble alkaline components, such as calcium hydroxide, sodium carbonate, etc. During the maturation process of cement, the wall surface is strongly alkaline, even if it is a mature cement wall surface, due to the moisture in the wall If it exists, it will also slowly bring the alkaline substances in the cement out of the...

[0002] With the development of industrialization, the pollution of the atmosphere is becoming more and more serious. The paint painted in the open air is easily corroded, and the life of the paint is short, so it needs to be painted frequently. At present, the paints used by people mainly include acid enzyme paint and nitro paint And baking paint, can not achieve the purpose of acid and alkali resistance

Wall cement contains soluble alkaline components, such as calcium hydroxide, sodium carbonate, etc. During the maturation process of cement, the wall surface is strongly alkaline, even if it is a mature cement wall surface, due to the moisture in the wall If it exists, it will also slowly bring the alkaline substances in the cement out of the wall. Normally, the alkaline substances can easily penetrate the putty layer to the paint surface. Under the action of the alkaline environment, the paint surface will appear white flowers and discoloration , uneven gloss and other phenomena, and in severe cases, powder falling and powdering will occur; in addition, the paint surface is not only eroded by the inner layer of alkaline substances, but also by carbon dioxide and acid mist in the air, which can easily cause discoloration , blistering and shedding
