Problems solved by technology

[0004] The existing sealing primers commonly used in the market are mainly film-forming primers, but the film-forming primers only form a layer of resin coating on the surface of building materials, which do not protect the interior of building materials, resulting in During long-term use, various problems will still occur. Therefore, it is necessary to develop a paint that can effectively penetrate into the interior of the building during the painting process, protect the interior of the building well, and reduce the situation of building alkali return. Penetrating coatings, an urgent problem to be solved

Abstract

The invention relates to the technical field of architectural coatings, in particular to a nano high-permeability seal primer emulsion and a preparation method thereof.The nano high-permeability seal primer emulsion is high in permeability, can permeate into a building in the coating process, has a good protection effect on the building and is excellent in salt and alkali flooding resistance; the particle size of the nano high-permeability seal primer emulsion is 40-60 nm, and the nano high-permeability seal primer emulsion comprises 50-100 parts of deionized water; 10-30 parts of a hard monomer; 10-30 parts of a soft monomer; 5-20 parts of a crosslinking monomer; 1-5 parts of a special functional monomer; 3-6 parts of an emulsifier; 1-2 parts of an initiator; the preparation method is completed by adopting a unique gradient feeding method, so that the synthesized latex particles have a multi-layer structure inside, the particle size of the emulsion is small, the emulsion particles can permeate into the building material in the brushing process, the effect of sealing internal pores of the building material is achieved, and a base material can be reinforced and reinforced.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a nanometer high-permeability sealing primer emulsion and a preparation method thereof. Background technique [0002] Generally, the silicate concrete used in home buildings or engineering buildings will appear salt frost-like crystals on the wall after a period of time, the rough house will be directly precipitated, and the decorated, paint, etc. will swell, peel, and fall off. , This phenomenon does not fade for many years, which seriously affects the appearance. This phenomenon is called "back to alkali" phenomenon. [0003] In the reality of the continuous increase of urban population, cities and towns are faced with the problem of not only meeting the housing needs of residents, but also ensuring the living conditions and environmental comfort of housing buildings. Among them, architectural coatings can not only play the function of decorating and beautifying...
