Problems solved by technology

The acrylic emulsion paint film is soft, but it has good aging resistance; the two-component polyurethane emulsion needs to add a curing agent when it is used, which is inconvenient to use, and its aging resistance is poor, and it is easy to yellow, etc.
Some people compound water-based acrylic with polyurethane, but it cannot fundamentally solve the above problems

Abstract

The invention provides a preparation method of waterborne woodenware finishes emulsion and the waterborne woodenware finishes emulsion prepared by the method. The method is that a nano TiO2 sizing agent is added during the synthetic process of the emulsion and comprises the following raw materials of the weight portion ratio: TiO2: 1.5 to 4; surfactant: 0.04 to 0.08; water: 3 to 6. The invention adopts the nano TiO2 sizing agent to participate in the polyreaction of the emulsion to make the nano TiO2 sizing agent distribute evenly in the emulsion and not move during drying the paint film, therefore, the waterborne woodenware finishes prepared by the emulsion not only has good stability, that is, precipitate will not happen even if stored over 6 months, but also has good resistance to temperature fluctuations, phototropy resistance and antibacterial property.

Description

technical field [0001] The invention relates to a water-based wood lacquer emulsion and the water-based wood lacquer, in particular to an acrylic acid emulsion of the water-based wood lacquer, a water-based wood lacquer prepared therefrom and a preparation method thereof. Background technique [0002] Most of the wood paints currently on the market are still oil-based paints, but oil-based paints have problems such as pollution and a large demand for organic solvents. Compared with oil-based wood lacquers, water-based wood lacquers are non-toxic, tasteless, and non-polluting. Therefore, the development and maturity of water-based wood lacquers is an inevitable trend in today's environmental protection issues. [0003] The usual preparation method of the existing water-based wood lacquer is: adding water-based wood lacquer emulsion, deionized water, additives, color paste, etc. into a mixing kettle, stirring evenly and then thickening. The performance of the emulsion has the...
