A self-drying/bakeable dual-purpose hydrolysis-resistant alkyd resin according to claim 3, wherein the catalyst is one of antimony-based, organotin-based, hypophosphorous acid; the hydrophilic solvent is selected from one or more of ethylene glycol monobutyl ether, propylene glycol methyl ether, propylene glycol butyl ether, dipropylene glycol methyl ether, diethylene glycol butyl ether, ethylene glycol methyl ether acetate, ethanol, n-butanol, isopropanol and butanol.
9. A self-drying/bakeable dual-purpose hydrolysis-resistant alkyd resin according to claim 3, wherein the neutralizing agent is selected from one of ammonia, N dimethylethanolamine, diethanolamine, triethanolamine, triethylamine, 1-methyldiethanolamine, sodium hydroxide.
10. A method for preparing the self-drying/baking dual-purpose hydrolysis-resistant alkyd resin as claimed in any one of claims 1 to 9, which comprises the following steps:
(1) Mixing dimethylol propionic acid and allyl glycerol ether, heating and reacting to obtain a special monomer;
(2) Putting polyalcohol, polybasic acid, special monomer and fatty acid into a reactor, slowly heating to 100-120 ℃, putting a catalyst into the reactor, slowly heating to 130-150 ℃, and preserving heat for 1-1.5h;
(3) Continuously heating to 5-10 ℃ per hour until the temperature reaches 210-240 ℃, carrying out heat preservation reaction, observing the water yield of the reaction, starting to measure the acid value when the water yield is 88-93%, and cooling to 150-160 ℃ after the acid value is less than 5-20 mgKOH/g;
(4) Then adding an aqueous monomer, reacting for 0.5-1h, and then cooling to 60-80 ℃;
(5) Adding hydrophilic solvent and neutralizing agent, and stirring completely and uniformly to obtain alkyd resin.
