Method of preparing and constructing rubber asphalt waterproof paint without bulge defect

Abstract

The invention provides a method of preparing and constructing a rubber asphalt waterproof paint without a bulge defect. The method comprises the steps of removing laitance and sundries on the surface of a concrete base surface with a quality defect; aiming at the dried concrete base surface, taking the rubber asphalt waterproof paint as a component A, taking a curing agent as a component B, and separately spraying the component A to the concrete base surface; spraying the component A and the component B when the concrete base surface of the component A is sprayed, and adding a wetting agent and a coupling agent into rubber asphalt waterproof paint; aiming at humid concrete base surface or the concrete base surface with open water, taking the rubber asphalt waterproof paint as the component A, taking a curing agent as the component B, spreading a thin layer of base layer processing agent used for absorbing and storing moisture on the concrete base surface, and brushing until the base layer processing agent is uniform by either a brush or a roller; and simultaneously spraying the component A and the component B on the concrete base surface.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a method for preparing and constructing a rubber asphalt waterproof coating without bulging defects. Background technique [0002] Spraying quick-setting rubber asphalt waterproof coatings has developed rapidly in China in recent years, and there have been many construction cases, but many problems have been found in the application process, especially in the national conditions of China's construction, the quality of concrete sometimes does not It meets the requirements of spraying quick-setting rubber asphalt waterproof coating, but the sand is serious, and the concrete is not up to standard due to poor vibration. After the rainy season in the south, even if the concrete base surface meets the qualified requirements, it is always in a wet state. During the spraying process, it was found that after spraying, it was exposed to the sun and bulged seriously, which not only affect...

[0002] Spraying quick-setting rubber asphalt waterproof coatings has developed rapidly in China in recent years, and there have been many construction cases, but many problems have been found in the application process, especially under the national conditions of China's construction, the quality of concrete sometimes does not It meets the requirements of spraying quick-setting rubber asphalt waterproof coating, but the sand is serious, and the concrete is not up to standard due to poor vibration.

After the rainy season in the south, even if the concrete base surface meets the qualified requirements, it is always in a wet state. During the spraying process, it was found that after spraying, it was exposed to the sun and the swelling was serious, which not only affected the appearance, but also the coating film was damaged after the swelling. become thinner and become a weak spot for water leakage
