Multifunctional water-based white primer and preparation method thereof

Abstract

The invention discloses multifunctional water-based white primer, which comprises the following components: titanium dioxide, talcum powder and calcium carbonate, and is characterized by comprising acrylic emulsion A and acrylic emulsion B, wherein acrylic emulsion A is styrene-acrylate emulsion which is self-crosslinked at the room temperature, and acrylic emulsion B is modified acrylic emulsion. The multifunctional water-based white primer provided by the invention can be constructed on a variety of wood product substrates, but also can be constructed on a variety of plastic substrates, at the same time, can be applied on the copper sheets, breaks through the situation of the simplification of the water-based white primer, and the performances meet the various requirements water-based wood white bottom and water-based plastic white bottom.

Description

A kind of multifunctional water-based white primer and preparation method thereof technical field The invention relates to a multifunctional water-based white primer and a preparation method thereof. Background technique With the tightening of environmental protection regulations, oil-based coatings are facing more and more severe challenges in the industrial field (especially wood and plastic fields), and some oil-based coatings have found it difficult to meet the requirements of international regulations on the limit of harmful substances in export coating products Therefore, in recent years, many downstream customers have actively requested the use of environmentally friendly water-based paints instead of oil-based paints, resulting in unprecedented development of water-based paints, especially water-based wood coatings. , children's beds, photo frames and wooden toys, etc.) are widely used, and now in the plastic field (such as mannequins, etc.), some customers also re...
