Abstract

The invention discloses an oil-resistant isolation primer, and a preparation method, a use method and a construction method thereof, and an obtained color-exposed composite waterproof coating layer. The oil-resistant isolation primer provided by the invention is composed of the following components in parts by weight: 50-90 parts of polymer latex, 1-10 parts of zinc oxide, 5-20 parts of a filler,1-12 parts of a reinforcing aid, 0.05-0.25 part of an anti-settling agent , 0.1-0.75 part of a dispersant, 0.01-0.25 part of a wetting agent, 0.3 -0.5 part of an antifoaming agent, 0.25-1.5 parts of an anti-oxidant, 0.25-1.0 part of a light stabilizer, 0.1-0.2 part of an anti-mildew auxiliary agent, 0-0.2 part of a pH value conditioning agent, 0.1-0.3 part of a thickening agent and 3-25 parts of deionized water, wherein the solid content of the polymer latex is 45-65%. The isolation primer disclosed by the invention can be used for effectively preventing oil from returning upwards and prolonging the color changing time of a colored elastic finish paint.

Description

technical field [0001] The invention belongs to the technical field of environmental protection materials, and in particular relates to an oil-resistant isolation primer, its preparation, use and construction methods, and the obtained colored exposed composite waterproof paint layer. Background technique [0002] For areas with cold winter and hot summer, spray quick-setting rubber asphalt waterproof coating and colored exposed elastic topcoat are used for waterproofing in exposed places. It is not only beautiful but also has good waterproof performance and high and low temperature resistance. However, at high temperature, the oil in the asphalt component of the sprayed quick-setting rubber asphalt waterproof coating will precipitate and return to the surface layer, resulting in discoloration of the surface layer, which limits the application of sprayed quick-setting rubber asphalt waterproofing materials. Studies have shown that the higher the temperature, the more intense ...
