Abstract

The invention discloses a waterproof sun-proof outer wall coating and a preparing method thereof, and relates to the field of novel building coatings. The coating is prepared from polyethersulfone resin, polyphenylene oxide resin, pure acrylic emulsion, modified starch, aerated aluminum powder, calcium-magnesium powder, zeolite powder, tetrachloroisophthalonitrile emulsion, sodium bentonite, dodecyl oleate, N-hydroxy methyl acrylamide, an anti-irradiation agent, a wetting dispersant reagent, a film forming auxiliary, an antioxidant and a flatting agent. The preparing method of the waterproof sun-proof outer wall coating includes the steps that the raw materials are mixed and milled; water are added into the milled materials and mixed to be even, and the waterproof sun-proof outer wall coating can be obtained. The waterproof sun-proof outer wall coating is easy and convenient to prepare and low in raw-material cost, has the excellent waterproof and sun-proof performance, and is long in service life and suitable for application and popularization.

Description

technical field [0001] The invention relates to the field of novel architectural coatings, in particular to a waterproof and light-resistant exterior wall coating and a preparation method thereof. Background technique [0002] Coatings are widely used, and are used on exterior walls, interior walls and floors of buildings. At present, when coatings are applied to the exterior walls of buildings, there are some problems. For example, the waterproof performance and light resistance of coatings are not good. The coating on the outer layer will fall off and crack, which will seriously affect the appearance, service life and product value of the building. Therefore, there is a need for improvement. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a waterproof and light-resistant exterior wall coating and a preparation method thereof. The exterior wall coating is simple and convenient to prepare, has low raw ma...
