Abstract
The invention discloses an oil-resistant isolation primer, a preparation method, a use method and a construction method thereof, and an obtained colorful exposed composite waterproof coating layer. The oil-resistant isolation primer disclosed by the invention comprises the following components in parts by weight: 50-90 parts of high polymer latex, 1-10 parts of zinc oxide, 5-20 parts of filler, 1-12 parts of reinforcing auxiliary agent, 0.05-0.25 part of anti-settling agent, 0.1-0.75 part of dispersing agent, 0.01-0.25 part of wetting agent, 0.3-0.5 part of defoaming agent, 0.25-1.5 parts of antioxidant, 0.25-1.0 part of light stabilizer, 0.1-0.2 part of mildew-proof auxiliary agent, 0-0.2 part of pH value regulator, 0.1-0.3 part of 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 effectively prevent the oil component from returning upwards, and the color change time of the color elastic finish paint is prolonged.
Description
Technical Field
The invention belongs to the technical field of environment-friendly materials, and particularly relates to an oil-resistant isolation primer, a preparation method, a use method and a construction method thereof, and an obtained colorful exposed composite waterproof coating layer.
Background
For areas cold in winter and hot in summer, the sprayed rapid-hardening rubber asphalt waterproof coating and the colored exposed elastic finish paint are used for preventing water on exposed occasions in a composite manner, and the waterproof paint is attractive, has good waterproof performance and also has high and low temperature resistance. However, at high temperature, oil in the asphalt component of the sprayed rapid-hardening rubber asphalt waterproof coating can be separated out and return to the surface layer, so that the surface layer is discolored, and the application of the sprayed rapid-hardening rubber asphalt waterproof material is limited. Research shows that the higher the temperature is, the more violent the molecular motion is, the shorter the time for the oil to analyze and penetrate through the color surface layer is, and the color change time of the surface layer is 20-45 days when the temperature is hotter in summer; in winter, the temperature is low, the molecular motion is slow, and the surface layer basically has no color change problem. In order to solve the problem that the color of a color surface layer is changed due to the fact that oil content returns upwards to penetrate through the color surface layer, the invention discloses an oil-resistant isolation primer.
