Abstract

The invention discloses a high-adhesion acrylic coating used for an outer wall. The coating comprises the following raw materials in parts by weight: 120-130 parts of major ingredients, 1-2 parts of triallyl isocyanurate, 1-2 parts of triethylene tetramine, 2-8 parts of medical stone powder, 1-5 parts of hard clay, 2-6 parts of coal ash, 1-5 parts of vermiculite powder, 1-3 parts of expanded perlite, 2-6 parts of ground calcium carbonate, 1-5 parts of quartz sand, 1-6 parts of aluminum oxide, 2-4 parts of a plasticizer, 1-2 parts of an anti-settling agent, 1-2 parts of a dispersing agent, 1-2parts of a flatting agent, 1-2 parts of a defoaming agent and 50-100 parts of deionized water. A nano-silica compound is prepared by the following process: mixing nano-silica, ethylene glycol, p-toluenesulfonic acid and adipic acid to obtain a mixture I, heating and stirring the mixture I under the protection of nitrogen, cooling to room temperature, adding epoxidized soybean oil and triphenylphosphine into the mixture I to obtain a mixture II, and continuously stirring the mixture II, so as to obtain the nano-silica compound.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an acrylic coating for exterior walls with high adhesion. Background technique [0002] Exterior wall coatings are used to paint building facades. Acrylic ester is a polymer material with strong adhesion and high film-forming properties. It has been widely used in the field of coatings. However, at present, acrylic coatings have poor adhesion and surface The disadvantage of poor gloss needs to be solved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a high-adhesion acrylic paint for exterior walls, which has high density, strong adhesion, and good compactness of the coating film, which not only prevents the transmission of corrosive media, but also is not easy to crack and has a glossy surface. High degree, high degree of decorative beauty. [0004] The present invention propo...
