Abstract

The invention belongs to the field of building materials and discloses a water-based seal primer for a penetrative building wall surface. The water-based seal primer comprises the following raw materials in parts by weight: 40-60 parts of de-ionized water, 0.1-0.3 part of a wetting agent, 0.1-0.2 part of a defoamer, 30-50 parts of modified acrylic emulsion, 5-10 parts of organic silicon emulsion, 0.1-0.5 part of a microbicide, 1-3 parts of a film forming aid and 0.1-0.2 part of a thickener. According to the water-based seal primer, the organic silicon emulsion and the modified acrylic emulsion are used as basic materials, and organic silicon groups are introduced, so that the penetrability of the coating is remarkably improved, the adhesion on the basic materials is excellent, the coating hardness and density can be enhanced, the water absorptivity is reduced, the effect of effectively sealing the basic materials is achieved, and the alkali efflorescence phenomenon is prevented.

Description

[0001] technical field [0002] The invention belongs to the field of building materials, and relates to a primer for building walls, in particular to a permeable water-based sealing primer for building walls. Background technique [0003] The functions of the sealing primer are: sealing the base, penetrating into the internal structure of the base, blocking the capillary pores in the base, reducing the number of open pores in the base, increasing the number of closed pores, inhibiting the penetration of paint moisture, making the penetration uniform, and making the base The absorption of the upper coating becomes uniform; the sealing primer can prevent moisture, anti-alkali isolation, and effectively isolate the alkali of the base layer to prevent the seepage of alkali from damaging the coating; it can reinforce the loose and weak base, Reinforce the base. [0004] The sealing primer is directly attached to the substrate, on which is attached the middle coat and the top co...
