Problems solved by technology

Its disadvantages are small cracks after being applied to the wall, poor strength, poor stain resistance and low temperature performance; in addition, due to the presence of styrene in the coating, the smell is quite strong; when the exterior wall is coated, a large amount of smell is emitted in the atmosphere. In addition, the curing time of this type of coating is relatively long. Therefore, it is necessary to pay attention to weather changes when coating, and it cannot be constructed during the continuous rainfall process. Therefore, it has great limitations.

Abstract

The invention belongs to the technical field of coatings, and particularly relates to an environment-friendly type building exterior wall coating material which is characterized by comprising titanium dioxide, talcum powder, calcium carbonate, mica powder, 2wt% of cellulose thickening agent solution, 10wt% of polyphosphate dispersing agent solution, 50wt% of polyacrylic acid emulsion, a mildew preventive, a defoaming agent, propylene glycol, ethylene glycol and purified water. The environment-friendly type building exterior wall coating material is prepared by adopting the steps of weighing raw materials, grinding granular raw materials, dissolving and filtering. The environment-friendly type building exterior wall coating material has the beneficial effects of no pollution, simple preparation method, less required devices, short curing time, low requirement on a coated environment condition, excellent mildew preventing effect, and the like.

Description

Technical field [0001] The invention is the field of coating technology, especially an environmentally friendly building exterior wall coatings with anti -mildew and coating. Background technique [0002] In existing technologies, most of the outer wall coatings commonly used are coatings prepared by the styrene -acrylic emulsion, pure acrylic emulsion, or elastic acrylic.The disadvantage is that it produces small cracks after coating the wall, poor strength, stain resistance and low temperature performance; in addition, because the lycrylene is used in the coating, the smell is quite strong; when coating the exterior wall, the smell is exuded in the atmosphere in large quantities of the atmosphere.Among them, pollution is caused; and the curing time of this type of coating is relatively long. Therefore, it is necessary to pay attention to weather changes when coating. It cannot be constructed during the rainfall of the connection. Therefore, it has great limitations. Invention ...
