Problems solved by technology

Among them, the porous structure makes it highly water-absorbing, which makes the surface of the coating not smooth enough, which easily causes the coating film to wrinkle, and may cause the coating film to dry too quickly, causing the top coat to crack and waste the top coat; and strong alkalinity can cause the resin in the coating to chemical degradation, accelerate the aging of the coating film, and reduce the service life of the coating

Abstract

The invention relates to a water-based alkali-resistant seal primer which is composed of the following components in parts by weight: 300 parts of water, 3-5 parts of dispersing agent, 2-3 parts of wetting agent, 1-2 parts of multifunctional assistant, 50-70 parts of talcum powder, 180-200 parts of heavy calcium carbonate powder, 100-120 parts of emulsion for epoxy alkali-resistant primers, 200-250 parts of emulsion for waterproof paints, 1-3 parts of bactericide, 30-50 parts of titanium white, 20-30 parts of film-forming assistant, 1-2 parts of defoaming agent, 2-3 parts of thickener, 0.5-1 part of leveling agent and 20-30 parts of antifreezing agent. The water-based alkali-resistant seal primer has the advantages of favorable water resistance, favorable sealability, favorable alkali resistance, favorable antifreezing property, long service life and the like, and is harmless to the environment and human body.

Description

technical field [0001] The invention relates to a building exterior wall primer, in particular to a water-based alkali-resistant sealing primer. Background technique [0002] With the increasing number of buildings using exterior wall coatings, especially for external wall insulation systems, choosing coatings is one of the most ideal market materials. However, some walls will have problems such as peeling, blistering, bursting, and discoloration, which will affect the use effect of the external wall insulation system and exterior wall coating. The reason, in addition to the quality of the paint, is mostly caused by the lack of understanding of the primer or the incorrect use of it. The base material of building exterior wall is mostly cement mortar or concrete surface, which is characterized by many voids and strong alkalinity. Among them, the porous structure makes it highly water-absorbing, which makes the surface of the coating not smooth enough, which easily causes th...
