Problems solved by technology

However, due to the large temperature difference between the north and the south of our country, the elastic latex paint produced by most enterprises is only suitable for use in this area.
At the same time, it is generally required that the elongation of elastic latex paint is ≥ 350%, but with the increase of elasticity, the stain resistance of elastic latex paint will gradually decrease, and the technical requirements must be balanced between the two
At present, most of the elastic latex paints produced in my country can guarantee good elasticity, but the stain resistance is generally poor, so they cannot be popularized and used in large areas.

Description

technical field [0001] The invention relates to an emulsion paint, in particular to an elastic emulsion paint for interior and exterior walls. The invention also relates to a preparation method of the elastic latex paint. Background technique [0002] With the introduction of national energy conservation and environmental protection requirements, the requirements for the thermal insulation performance of building materials are getting higher and higher. There is a large difference between the north and the south of my country. The north is cold in winter and needs to be heated. However, the temperature difference between indoors and outdoors is large. The existing walls cannot effectively prevent the dissipation of heat. It is necessary to increase the supply and demand of heat and increase energy consumption. However, the summer weather in the southern region is relatively hot, which requires a large amount of power consumption to reduce the indoor temperature. Also due to...
