Description
Technical field
The present invention relates to paint field, more specifically, it relates to a kind of water soluble acrylic acid paint added with titanium dioxide and
Its preparation method.
Background technology
Coating, is commonly called as " painting ", be it is a kind of can be coated in body surface by different construction technologies, form adhesion jail
Gu, the continuous solid-state film substrate with some strength, object can be played protection, decoration and characteristic functions effect.Tradition
Coating can discharge a large amount of volatile organic matters (VOC) after use, cause air quality to be deteriorated, human body is in the short time
The VOC of the interior a large amount of high concentrations of suction can make lung tissue forever be damaged, and Long Term Contact more damages respiratory system, liver, kidney
The function such as dirty, triggers organ failure.When these traditional coating are used as being applied to the paint on wall, these coating need
It can just volatilize completely for a long time, this will influence the health of user.With the enhancing of environmental consciousness, countries in the world are all made in succession
The limit standard and regulation of volatile organic matter (VOC) discharge are ordered.
At present, in each kind of environmental protection paint, water soluble acrylic acid paint is with its green (low VOC emission), energy-conservation
The features such as, developed rapidly in countries in the world.Application publication number discloses for CN104745028A Chinese patent
