The present invention relates to the technical field of water-based coatings, and in particular relates to good-weather and water resistance water-based alkyd resin, alkyd resin is obtained by fatty acid method, and by reaction of epoxy groups of epoxy organosiloxane and alcoholic hydroxyl groups and carboxyl groups of an alkyd resin molecular chain, organosiloxane chain segments are introduced into the water-based resin system for synthesis of the water-based epoxy organosiloxane-modified alkyd resin with excellent water resistance, stain resistance, weather resistance, smoothness and corrosion resistance. An epoxy organosiloxane monomer contains a methoxysilane inorganic active functional group, silicon hydroxyl formed by hydrolysis of the functional group may be condensed with inorganic material surface hydroxyl to improve the water-based alkyd resin adhesion to a metal, glass and plastic substrate, meanwhile by the introduction of the organosiloxane chain segments into the alkyd resin branched portion, the drying properties, weather resistance, heat resistance and water resistance of the water-based alkyd resin can be greatly improved.

The invention discloses water-based alkyd-acrylate dispersion as well as a preparation method and application thereof. The water-based alkyd-acrylate dispersion is prepared from the following raw materials: alkyd resin, an acrylate monomer, texanol, an initiator and a neutralizer, wherein the alkyd resin comprises the following raw materials: rosin, vegetable oil, polyol, phthalic anhydride, maleic anhydride, trimellitic anhydride, D40 solvent oil, an alcoholysis catalyst, an esterification catalyst and texanol. The water-based alkyd-acrylate dispersion is prepared from the raw materials through a chemical copolymerization method; wherein the particle size of the nano titanium dioxide is 178-188 nm, the Mw/Mn is 2.93 to 2.96, the grafting rate is 51-57%, the particle size is small and uniform, the stability is better, the grafting rate is high and the molecular weight distribution is more uniform; a molecular chain contains conjugated double bonds, carboxyl and other functional groups,so that the crosslinking density can be improved, the water absorption rate of a paint film is reduced, and the hardness, adhesive force, salt fog resistance and other properties of the paint film are improved.

The invention discloses one-step forming solvent type single-component quick drying hammer finish which comprises, by weight, 50-70 parts of alkyd resin, 13-17 parts of modified liquid resin, 12-15 parts of methylbenzene, 0.1-0.4 part of patent organic auxiliaries, 3-5 parts of non-floating aluminum paste, 4-6 parts of xylene, 0.2-0.4 part of hammer tone auxiliaries, 1.0-2.5 parts of polyethylene wax, 0.5-1.5 parts of compound driers and 0.1-0.3 part of anti-skinning agents. The invention further discloses a preparation method of the one-step forming solvent type single-component quick drying hammer finish. When in construction, the one-step forming solvent type single-component quick drying hammer finish can be formed only by one-step spraying without grounding or sagging, decorative patterns are clear, stereoscopic impression is high, diluting agents are no longer added in construction, construction can be performed through direct uncapping and uniform stirring by non-specialized persons, and construction difficulty is greatly reduced.
