Problems solved by technology

The reasons for this problem are: On the one hand, it may be that the surface strength of the concrete base is small, which is lower than the bonding force between the waterproof coating and the concrete base, resulting in the failure to form a good bond between the waterproof coating and the concrete base. On the other hand, during the construction process, it is diffic

Abstract

The invention provides a method for preparing and constructing a primer of a waterproof coating and the primer of the waterproof coating. The primer of the waterproof coating is composed of a component A, a component B and a component C, wherein the component A is epoxy resin which comprises epoxy resin E51 or epoxy resin E44; the component B is a non-ionic emulsifier modified amine curing agent which comprises at least one of modified fatty amine and cycloaliphatic amine; the component C is water; when the component A is the epoxy resin E51, the primer comprises the substances in parts by weight: 15-20 parts of the component A, 25-30 parts of the component B and 50-60 parts of the component C; when the component A is the epoxy resin E44, the primer comprises the substances in parts by weight: 15-20 parts of the component A, 10-20 parts of the component B and 60-75 parts of the component C. According to the scheme provided by the invention, by using the primer of the waterproof coating, bubbling and stripping phenomena of constructed rubber asphalt waterproof coating are avoided.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a waterproof coating primer and a method for preparing and constructing the waterproof coating primer. Background technique [0002] In the waterproof construction project where the base material is concrete, in order to prevent water seepage on the concrete base, rubber asphalt waterproof coating will be sprayed on the concrete base. [0003] However, after the waterproof coating is sprayed, when the ambient temperature is high, the waterproof coating sometimes has a bulging phenomenon, especially in construction sites with high water content such as underground and foundation pits, the bulging phenomenon is more common. This is mainly due to the fact that there is always moisture in the concrete base. Under high temperature conditions, the free water molecules contained in the concrete base reach the base surface along the capillary channels and tiny cracks of the concrete to...
