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 difficult to clean the floating ash on the concrete base surface thoroughly. Due to the existence of floating ash, it hinders the bonding between the waterproof coating and the concrete base, and the connection between the waterproof coating and the concrete base There is no good contact between them, resulting in the detachment of the waterproof coating from the concrete base

Abstract

The invention provides a method for preparing and constructing a waterproof coating primer and a waterproof coating primer, the waterproof coating primer is composed of A component, B component and C component, and the A group Divided into epoxy resin, the epoxy resin includes epoxy resin E51 or epoxy resin E44, the B component is non-ionic emulsifier modified amine curing agent, including modified aliphatic amine and alicyclic At least one of the group amines, the C component is water; when the A component is the epoxy resin E51, the ratio of each substance in the primer is: the A component is 15 to 20 parts by weight , the B component is 25 to 30 parts by weight, and the C component is 50 to 60 parts by weight; when the A component is the epoxy resin E44, the ratio of various substances in the primer is: The A component is 15-20 parts by weight, the B component is 10-20 parts by weight, and the C component is 60-75 parts by weight. According to the solution of the present invention, the use of the waterproof coating film primer avoids the phenomenon of bulging and detachment after the construction of the rubber asphalt waterproof coating.

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...
