Problems solved by technology

[0003] Even so, in the prior art, the diluent is selected to be environmentally friendly and green water, so that the prepared paint will not cause volatile organic compounds in the film drying process, and avoid environmental pollution; however, in the prior art, for the preparation of the paint The process is still relatively complicated, and the selection and matching of raw materials are unreasonable, resulting in high preparation costs of the obtained alkyd paint, unstable product quality, poor adhesion, poor anti-rust performance, low hiding power, and easy to fall off. Makes the anti-corrosion period of steel structure etc. shorter

Abstract

The invention relates to the technical field of oil paint and especially relates to a waterborne alkyd paint and a preparation method thereof. The waterborne alkyd resin, titanium dioxide flour, barium sulfate, ferrotitanium flour, waterborne dispersing agent, defoamer, antirust agent, thickener and water are selected and coordinated, so that the acquired waterborne alkyd paint has quality stability, high adhesive force, higher antirust capacity and higher covering capacity; the expulsion rate in the steel structure can be reduced; the anticorrosive period of the steel structure can be prolonged.

Description

technical field [0001] The invention relates to the technical field of paints, in particular to a water-based alkyd paint and a preparation method thereof. Background technique [0002] Most of the alkyd paints in the prior art use organic solvents as diluents, so that during the drying process of the paint film, a large amount of organic solvents are volatilized and released into the air, causing pollution to the environment and waste of raw materials. For this reason, there are a large number of researchers to use water as diluent, so that in the process of drying the paint film, release water vapor, avoid environmental pollution, and reduce the production cost of paint; The preparation method of modified alkyd resin coating uses water as the diluent, is non-toxic, non-flammable, and has no pollution to the environment, and can be applied to the field of metal anticorrosion; another example is "water-based acrylic modified alkyd enamel and Its preparation method "contains...
