Description
Technical Field
The invention relates to the technical field of coatings, in particular to a multifunctional primer with consolidation and permeability.
Background
Most of putty layers for buildings are loose and low in strength, meanwhile, concrete has a porous structure, water and ions can permeate into the interior of the putty layers through the pores of the putty layers to corrode the putty layers, the service life of the buildings and the service life of finish paint are directly affected, and the loosening of base layers is one of the main reasons for causing quality defects of paint films.
Most of the building primers in the current market adopt acrylic polymers produced by common processes as film-forming substances, and the emulsion has poor permeability and no consolidation, so that a good base reinforcing effect cannot be achieved
Concrete is also a brittle material, and under the action of stress, the concrete is easy to crack and lose efficacy, so that huge economic loss and serious potential safety hazard are caused. Therefore, concrete protection is an important problem related to the national civilization and industrial construction, and the development of high-performance concrete protection materials is an important direction for prolonging the service life of concrete; therefore, how to add a reinforcing layer on the concrete to form a putty layer with effective protection function is a difficult problem.
