Waterproof paint directly used for water seepage surface

Abstract

The present invention discloses one kind of waterproof paint capable of painted directly onto water seeping concrete surface. The paint contains base material component including epoxy resin and curing agent component containing amine compound. The paint may be also applied directly in water and has simple application process, strong adhesion in the interface, high seepage resistance, less environmental pollution and other advantages.

Description

technical field [0001] The invention relates to a waterproof paint, in particular to a paint that can be directly cured on a water-permeable concrete surface. Background technique [0002] Current wet surface waterproof coatings are generally only suitable for building concrete bases with a moisture content of less than 8%. However, in practical applications, the construction environment is very humid and even seeps in many cases. In the case where the surface of the base layer is covered with water molecules to form an isolation layer, the polymer material cannot take root on the base layer or generate strong attraction with the solid molecules of the base layer, and it is impossible to have strong adhesion, and it is bound to be easy to peel and peel off, thus losing the waterproof function . [0003] The fifth issue of volume 23 of "Shanghai Chemical Industry" once reported the polyurethane waterproof coating that can be applied to the concrete base in the wet saturated...

AI Technical Summary

Problems solved by technology

This special reactive component can convert water into a polyurethane crosslinking agent, and the introduction of hydroxyl groups in component B increases the affinity between the coating and the base layer, so the coating does not foam on the wet surface. It has strong adhesion, but the adhesion of the coating film is significantly reduced when it is applied on the water seepage surface

In addition, other waterproof coatings such as cyanide also have the same problem.
