Color steel waterproof heat-insulating coating and method for preparing same

Abstract

The invention provides a color steel waterproof heat-insulating coating and a method for preparing the same. The color steel waterproof heat-insulating coating is prepared from the following raw materials in part by weight: 15 to 20 parts of vitrified small ball, 3 to 5 parts of sepiolite, 20 to 30 parts of building waterproof glue, 0.2 to 0.5 part of polypropylene fiber, 5 to 10 parts of aluminate cement, 15 to 20 parts of white Portland cement, 2 to 4 parts of sericite, 0.5 to 1 part of dispersible polymer powder, 0.2 to 0.4 part of Dibutyl phthalate, 0.2 to 0.4 part of polyscrylamide, 0.3 to 0.5 part of preservative, 0.2 to 0.4 part of defoaming agent and 10 to 15 parts of water. The color steel waterproof heat-insulating coating is prepared by blending liquid materials and powder materials, and is a combination of organic and inorganic materials, and after stirring, emulsion and polymerization, the waterproof heat-insulating property is improved to over 98 percent; and when the coating is used for steel structural surfaces in steel products, chemical grouting and the like, the bonding force is strong, the environmental protection energy saving capability is improved by over 65 percent if the coating is 10mm in thickness, and the waterproof property is high, and the service life is as long as 30 years. Thus, the coating of the invention is a preferable color steel surface waterproof heat-insulating coating.

Description

technical field [0001] The invention relates to a color steel waterproof and thermal insulation paint and a preparation method thereof. Background technique [0002] At present, the commonly used color steel insulation materials in China are rock wool, glass wool, steel wire mesh, aluminum foil paper and other materials. These materials are not waterproof, easy to rust and fall off, and have a short lifespan. They are polluted by fibers and are not environmentally friendly and energy-saving. Contents of the invention [0003] The object of the present invention is to provide a color steel waterproof and heat-insulating coating made of materials with good water resistance and strong thermal insulation and its preparation method. [0004] In order to achieve the above object, the technical solution of the present invention is: a color steel waterproof and thermal insulation coating, characterized in that: it is made of the following materials in proportion by weight: 15-20 p...
