The silane coupling agent is especially gamma- (methacryloyloxy) propyltriisopropoxysilane selected, and has long-term stability in the presence of water as a solvent. The nonionic surfactant is not limited to polyethylene glycol diglycidyl ether or polypropylene glycol diglycidyl ether, and is used singly or in combination, and the dosage and the combination directly influence the hydrophilicity and also influence the physical performance after film formation.
Methyl methacrylate, isobornyl methacrylate, hydroxyethyl methacrylate, dicyclopentadienyl acrylate, acrylic acid, and the like, each function as follows: methyl methacrylate imparts high hardness to the coating film; isobornyl methacrylate endows the coating film with high gloss and high toughness; hydroxyethyl methacrylate provides hydroxyl groups for drying the coating film, so that the hydroxyl groups and silicon hydroxyl groups are subjected to crosslinking reaction and are cured to form a film; double bonds on the acrylic acid dicyclic pentadiene ester and oxygen are subjected to oxidative polymerization reaction, so that the strength of the coating film is improved; acrylic acid provides carboxyl groups to promote the crosslinking curing reaction under baking conditions.
The invention relates to a preparation method of stainless steel water-based resin, which comprises the following specific processes: firstly, adding a cosolvent and a reactive nonionic surfactant into a reaction bottle, and uniformly mixing other monomers, 80% of an initiator and a chain transfer agent to form a mixture. Introducing nitrogen into the reaction bottle, heating to 130-135 ℃ within 1 hour under stirring, keeping refluxing for 15 minutes, uniformly dropwise adding the mixture, finishing dropwise adding within 2-3 hours, continuously preserving heat and refluxing for 1 hour, then supplementing the remaining 20% of initiator twice, supplementing at an interval of 1 hour, continuously preserving heat and refluxing for 2 hours after the completion of supplementing, testing the acid value once every 1 hour, cooling to 75-85 ℃ within 1 hour when the acid value is reduced to be less than 5mgKOH/g, dropwise adding deionized water into the reaction bottle within the temperature range for 1 hour, and continuously stirring for 0.5 hour after the completion of dropwise adding, thereby discharging. Thus, the self-crosslinking aqueous resin is formed through free radical polymerization and esterification reaction in the presence of an initiator and a chain transfer agent. The resin is coated on a stainless steel plate, is heated to 160-180 ℃, can be further cured into an insoluble and infusible transparent coating film through a crosslinking reaction after being baked for 10-30 min, and is acid-base resistant, salt mist resistant, water-boiling resistant, free of yellowing at high temperature and excellent in performance.
