One kind and a manufacturing method interior alkali primer

The present invention provides a method of manufacturing the interior alkali primer. Interior alkali primer of the present invention is a synthetic resin emulsion as a binder, adding pigments, fillers, various additives prepared from a synthetic resin emulsion coating, commonly known as latex paints. Interior alkali primer component of the present invention comprises a synthetic resin emulsion, a synthetic resin emulsion is 12.0-18.0% by weight of the synthetic resin emulsion and styrene-acrylic copolymer. Economic and environmentally friendly interior alkali primer of the present invention, can increase the adhesion of paint, some hiding power; closed and can have excellent on concrete buildings substrate, the substrate can be effectively closing the number of open pores, division of the substrate base can effectively isolate and prevent bleeding base points break in the coating to the substrate can be reinforced and the reinforcing effect.
