High-coating-rate thick-film water-based roller-coating alkyd paint and preparation method thereof

The invention provides a high-coating-rate thick-film water-based roller coating alkyd paint and a preparation method thereof. The high-coating-rate thick-film water-based roller coating alkyd paint mainly comprises the following components in parts by weight: 20-30 parts of water-based resin, 1-2 parts of an assistant A, 2-5 parts of an assistant B, 0.5-1 part of a neutralizer, 20-40 parts of pigment and filler, 10-30 parts of distilled water, 0-2 parts of a thickener and 0-3 parts of a solvent. According to the roller-coating alkyd paint, the components are adjusted, the weight parts of theraw materials are adjusted, the performance of the high-volume solid filler is exerted to the maximum extent, and the thickness of a paint film after coating is increased, so that the salt fog resistance and the water resistance of the paint are improved. The roller-coating alkyd paint is used for coating equipment and has the advantages of good salt spray resistance and water resistance. 本发明提供了一种高涂布率厚膜水性辊涂醇酸涂料及其制备方法，主要包括
