Abstract

A method for preparing an exterior wall paint using magnesium slag to absorb CO2, relates to a preparation method for an exterior wall paint, in which magnesium slag is sieved through a 200-mesh sieve, used as a filler for the paint, mixed evenly with other components of the paint, and prepared into CO2-absorbing exterior wall coatings; magnesium slag powder can be used alone as a filler for exterior wall coatings, or in combination with one or more of quartz powder, talcum powder, mica powder, and lithopone as a filler for coatings; such as preparing styrene-acrylic emulsion- Magnesium slag exterior wall coating, silicon acrylic emulsion-magnesium slag exterior wall coating, epoxy resin-magnesium slag exterior wall coating, water glass-magnesium slag exterior wall coating, hydrosol inorganic polymer-magnesium slag exterior wall coating, silica sol- Magnesium slag exterior wall coating, potassium silicate-magnesium slag exterior wall coating. The invention solves the problems that the pile of magnesium slag occupies a large amount of cultivated land, the enterprise pays a huge slag discharge fee, and the magnesium slag pollutes the environment. The use of magnesium slag to make coatings can save a lot of production costs, and can also fix CO2, bringing huge environmental and social benefits.

Description

technical field [0001] The invention relates to a preparation method of exterior wall paint, in particular to a method for absorbing CO by using magnesium slag 2 Preparation method of exterior wall paint. Background technique [0002] China is a country with large magnesium resources, and the reserves of high-quality magnesium smelting raw materials such as magnesite, dolomite and salt lake magnesium resources are very rich. According to the data, the amount of raw magnesium produced and exported by China has reached 85% of the world's raw magnesium production. The output of primary magnesium keeps growing at a rate of more than 10% year by year. At present, the domestic smelting of magnesium mainly adopts the silicon thermal reduction method, and the process is: dolomite (MgCO 3 ·CaCO 3 ) in a rotary kiln to produce calcined white (MgO·CaO) by calcining at 1100-1200°C, then grind the calcined white into powder, mix it with ferrosilicon and fluorite powder, and make balls...
