Abstract

The invention discloses a waterproof paint used for building external walls, and a preparation method thereof. The waterproof paint used for building external walls comprises, by weight, 20 to 40 parts of light calcium carbonate, 10 to 20 parts of zinc sulfide, 5 to 10 parts of hollow glass bead, 5 to 12 parts of titanium dioxide, 10 to 20 parts of a water-absorbent resin, 8 to 14 parts of a filmforming aid, 5 to 12 parts of polyacrylonitrile fiber, 10 to 20 parts of a flocculating agent, 8 to 18 parts of polyvinyl alcohol, 4 to 12 parts of wood fiber, and 5 to 10 parts of hydrophobic white carbon black. The preparation method is simple; the obtained waterproof paint possesses excellent water resistance, thermal insulation performance, and cracking resistance; finished product construction is convenient; and bonding force and stretching resistance are high.

Description

technical field [0001] The invention relates to the technical field of preparation of waterproof coatings, in particular to a waterproof coating for building exterior walls and a preparation process thereof. Background technique [0002] Traditional waterproof materials mainly include flexible waterproof materials such as waterproof membranes, waterproof coatings, and sealing ointments, as well as rigid waterproof materials that are based on cement substrates and added with liquid medicine and other additives. Most waterproof projects in my country use traditional waterproof materials, which have disadvantages such as poor aging resistance, low tensile strength, and sensitivity to temperature. Traditional waterproof coatings are used to waterproof external walls, which are prone to aging, cracking, deformation, breaking, and delamination. Contents of the invention [0003] The object of the present invention is to provide a kind of exterior wall waterproof paint for build...
